Line rental, installation fees, monthly costs, early termination charges, and total cost of ownership for UK business broadband.
Standard business broadband: £25-60/month for speeds 50-100Mbps (FTTC - fibre to cabinet). Typical UK small business package: 80Mbps download, 20Mbps upload for £35-45/month including line rental. Residential broadband cheaper (£20-30/month) but breaches business use terms and lacks SLA guarantees.
Full-fibre (FTTP): £40-80/month for symmetric speeds 100-1000Mbps. Example: 300Mbps symmetric connection £50-65/month. Upload speeds match download (critical for cloud backups, VoIP, video conferencing). Premium for symmetry justified if uploading large files daily or running 10+ video calls simultaneously.
5G business broadband: £30-50/month for 50-150Mbps average speeds. No installation needed (plug-and-play router). Good for temporary sites, pop-up shops, or locations without fibre infrastructure. Data caps common (500GB-unlimited/month). Speed varies by network congestion and location (test signal strength first).
Standard FTTC installation: £0-100 depending on provider and promotion. Engineer visit usually included if activating new line. Existing line reactivation often free. Installation timeline: 10-15 working days from order to activation. Can be faster (5-7 days) if infrastructure already in place.
Full-fibre (FTTP) installation: £100-300 standard charge, often waived on 24-36 month contracts. Requires fibre cable run from street cabinet to premises. Internal wiring and router installation included. Timeline: 3-6 weeks if fibre available at cabinet, 8-12 weeks if new fibre build required to reach your premises.
Civil works (non-standard installs): £500-2,000+ if extensive digging/drilling needed. Example: fibre run across car park, through concrete walls, underground duct installation. Get written quote before committing. Some providers absorb civil works cost on long contracts (36 months+). ROI calculation: £1,500 civil works ÷ 36 months = £42/month effective cost increase.
Static IP addresses: £5-10/month per IP. Essential for remote access to office servers, CCTV systems, VPN connections. Dynamic IPs (free) change regularly, breaking remote access configurations. Most businesses need 1 static IP minimum. Multiple IPs (£8-12/month each) needed for hosting multiple services or separate network segments.
Router rental vs purchase: Rental £5-10/month (£60-120/year), purchase £100-300 one-time. Break-even 10-30 months. Rental advantage: free replacement if fails, automatic upgrades. Purchase advantage: better quality routers available, no ongoing cost, keep when switching providers. Business-grade routers (£200-500) offer VPN, advanced firewalls, traffic shaping - worth investment for 10+ users.
Out-of-hours support: £10-25/month for 24/7 technical support. Standard support: 9am-6pm weekdays. Premium support: 24/7/365 with faster response times. Worth it for businesses operating evenings/weekends or highly dependent on connectivity (e.g. hospitality, retail, e-commerce). Some providers include 24/7 support on premium packages.
12-month contracts: Early exit fee typically £150-250 or remaining months × monthly cost (whichever lower). Example: 6 months remaining on £50/month contract = £300 or capped fee £200 = you pay £200. Some providers pro-rate (6 months × £50 = £300 ÷ 2 = £150 if leaving halfway through).
24-36 month contracts: Higher exit fees £300-600. Calculate: remaining months × £40/month. 18 months left = £720 potential fee. Some providers cap at £500. Always check exit terms before signing long contracts. Only justify long lock-in if significant discount (15-25% off standard pricing) or waived installation costs (£300+ saving).
Rolling monthly contracts: 30 days notice, zero exit fees. Pay premium (10-20% more monthly) for flexibility. Example: 12-month £45/month vs rolling monthly £52/month. Extra £7/month (£84/year) buys flexibility to switch anytime. Worth it for businesses with uncertain location (short-term lease, expansion planned, relocation possible).
3-year TCO example - Standard broadband: Monthly £40, installation £0 (waived), static IP £8/month, router rental £7/month. Total: (£40 + £8 + £7) × 36 months = £1,980. Add potential downtime costs: 4 hours/year @ £200/hour revenue loss = £800 lost revenue/year × 3 years = £2,400. True TCO: £4,380 over 3 years (£122/month effective cost including downtime).
3-year TCO example - Premium full-fibre: Monthly £65, installation £200, static IP £8/month, router purchase £250. Total: £200 + £250 + (£65 + £8) × 36 = £3,078. Higher upfront but better SLA reduces downtime: 1 hour/year @ £200/hour = £600 lost over 3 years. True TCO: £3,678 (£102/month). Premium connection actually cheaper when factoring downtime reduction.
Break-even calculation: Premium costs £18/month more (£65 vs £47 standard with IP + router). Saves 3 hours downtime/year = £600/year. Break-even: £18 × 12 months = £216/year extra spend vs £600/year downtime savings = net £384/year benefit. Premium justified if connectivity critical to operations. Not worth it for businesses tolerating occasional 4-hour outages without major revenue impact.
Mid-contract price rises: Most providers can increase prices mid-contract (RPI + 3.9% formula common). £50/month contract with 6% RPI = £53/month after year 1, £56.18/month after year 2. On 36-month contract, year 3 costs 12-18% more than year 1. Factor this into TCO calculations.
Fixed-price guarantees: Some providers offer price-lock for contract duration (rare, usually 10-15% premium). Example: £55/month fixed vs £50/month with annual increases. Year 1: pay £5/month extra = £60/year. Year 2-3: save vs increases. Total 3-year comparison: fixed £1,980 vs variable £1,882 year 1 + £1,996 year 2 + £2,116 year 3 = £5,994. Fixed saves £1,014 over 3 years on this example.
Contract renewal timing: Negotiate new contract 60-90 days before expiry to avoid out-of-contract rates (30-50% premium). Out-of-contract £50/month becomes £65-75/month. Set calendar reminder 120 days before contract end to start comparison shopping. Leverage competitor quotes to negotiate retention deals (10-20% discount common for loyal customers).
We'll compare providers and calculate your true total cost of ownership including installation, add-ons, and potential downtime costs.
Get Quote →Technology comparison, speed differences, reliability metrics, contention ratios, and cost analysis for each connectivity type.
Technology: Fibre optic from exchange to street cabinet, copper phone line from cabinet to premises. Maximum speed limited by copper distance - longer copper run = slower speeds. Typical: 50-80Mbps download, 10-20Mbps upload. Asymmetric speeds (download much faster than upload).
Availability: 95%+ UK business premises. Most common business broadband type. Installation quick (10-15 days) if phone line exists. Copper infrastructure ageing - being phased out by 2027 (PSTN switch-off). Not recommended for new contracts longer than 24 months due to phase-out timeline.
Cost: £25-45/month for 50-80Mbps. Installation usually free or £50-100. Contention ratio 20:1 or 50:1 (shared bandwidth with 20-50 other businesses). Performance degrades during peak hours (9am-5pm). Suitable for: small offices (under 10 users), basic internet use, limited cloud application usage.
Technology: Fibre optic cable direct from exchange to premises (no copper involved). Symmetric speeds - upload matches download. Typical packages: 100/100Mbps, 300/300Mbps, 1000/1000Mbps (1Gbps). Maximum potential 10Gbps+ (future-proof infrastructure). Distance doesn't degrade speed unlike copper.
Availability: 50-60% UK business premises (growing rapidly). Check postcode availability before signing office lease. New builds almost always have FTTP. Older buildings may need civil works (£500-2,000). Government targeting 85% UK coverage by 2025, 99% by 2030. Worth waiting 3-6 months for FTTP if coming to your area rather than settling for FTTC.
Cost: £40-80/month depending on speed tier. 300Mbps symmetric typically £50-65/month. Installation £100-300 (often waived on 24-36 month contracts). Contention ratio usually 20:1 or better (some providers offer 10:1 on premium packages). Best for: cloud-heavy businesses, video conferencing, large file transfers, VoIP phone systems, 10+ users.
Technology: Mobile 5G network provides internet connectivity via cellular router. No cables required (plug-and-play setup). Speeds 50-300Mbps typical (variable based on network congestion and signal strength). Latency higher than fixed-line (20-40ms vs 5-15ms fibre). Not suitable for latency-sensitive applications (VoIP can be problematic).
Availability: 40-50% UK coverage currently (major cities well covered, rural areas patchy). Test signal strength at exact premises location before committing - performance varies dramatically within same street. Indoor signal weaker than outdoor (thick walls block 5G signal). External antenna may be needed (£100-300 extra).
Cost: £30-50/month for 500GB-unlimited data. Router included (£200-400 value). No installation costs or delays (plug in and go). Data caps common - unlimited plans £45-60/month. Best for: temporary sites (pop-ups, construction offices, event venues), backup connectivity (automatic failover), locations without fibre access. Not recommended as primary connection for mission-critical businesses.
Technology: Dedicated fibre circuit exclusively for your business (uncontended 1:1 ratio). Symmetric speeds guaranteed 24/7. Common speeds: 10Mbps, 100Mbps, 1Gbps, 10Gbps. SLA guarantees 99.9-99.99% uptime. Fix time guarantees 4-6 hours (vs 24-48 hours standard broadband). Enterprise-grade reliability.
Availability: Available anywhere fibre infrastructure exists but requires bespoke installation. Installation survey required (£200-500, usually refunded on order). Lead time 60-90 days from order to activation (vs 10-20 days standard broadband). Distance from nearest exchange affects installation cost - longer run = higher cost.
Cost: £300-1,500/month depending on speed and location. 100Mbps leased line typically £400-600/month. Installation £1,000-5,000 (often waived on 36-60 month contracts). Worth it for: multi-site businesses needing reliable inter-office connectivity, data centres, businesses where 1-hour downtime costs £1,000+ in lost revenue. Overkill for most small businesses under 50 employees.
Downloading 1GB file: FTTC 80Mbps = 102 seconds. FTTP 300Mbps = 27 seconds. 5G 150Mbps = 54 seconds. Leased line 1Gbps = 8 seconds. For businesses downloading large datasets, CAD files, or video content daily, FTTP or leased line saves significant time.
Uploading 500MB backup: FTTC 20Mbps upload = 204 seconds. FTTP 300Mbps upload = 14 seconds. 5G 50Mbps upload = 82 seconds. Leased line 1Gbps upload = 4 seconds. Upload speed critical for cloud backups, sending large files to clients, video conferencing quality. FTTC's slow upload (10-20Mbps) problematic for modern cloud-based workflows.
10-person video conference: Bandwidth needed: 10 users × 3Mbps = 30Mbps upload minimum. FTTC 20Mbps upload = struggles with 10 simultaneous calls. FTTP 300Mbps upload = handles 100 simultaneous calls easily. 5G variable upload (20-80Mbps) = risky for critical meetings. Leased line guaranteed bandwidth = perfect quality always. Video-heavy businesses need minimum 100Mbps symmetric for reliable performance.
FTTC/FTTP uptime: Typical SLA 99-99.5% uptime (43-87 hours downtime/year allowed). Fix time target 24-48 hours. No compensation for most outages under consumer/standard business contracts. Better uptime on business-grade packages with enhanced SLA (99.5-99.9% uptime, fix within 12 hours, compensation for breaches).
5G uptime: No SLA guarantees on most consumer-grade 5G broadband packages. Network congestion during peak hours reduces speeds 30-50%. Weather affects signal (heavy rain degrades 5G performance). Power cut = no internet (vs fibre which often continues working if router on UPS battery backup). Reliability insufficient for mission-critical operations.
Leased line uptime: SLA guarantees 99.9-99.99% uptime (8.76 hours to 52 minutes downtime/year). Fix time guarantees 4-6 hours with financial penalties for breach. Compensation £100-500 per hour down depending on contract. Diverse routing options (two separate physical paths) for 99.999% uptime. Enterprise-grade reliability justifies 5-10x cost premium for critical connectivity.
Choose FTTC if: Small office (under 10 users), basic internet browsing/email, limited budget (£25-45/month), short-term office (under 24 months), FTTP not available. Warning: PSTN switch-off by 2027 means FTTC being phased out - don't sign contracts beyond 2026.
Choose FTTP if: Cloud-based business applications (Office 365, cloud ERP), regular video conferencing (5+ calls daily), large file uploads/downloads, VoIP phone system, 10+ users, long-term office (36+ months). Best value for most modern businesses. Futureproof technology - speeds can be upgraded to 1Gbps+ without infrastructure changes.
Choose 5G if: Temporary site (construction office, pop-up shop, event venue), backup connectivity alongside primary fibre, remote location without fibre access, need instant setup (plug-and-play). Not recommended as sole connection for businesses with 10+ employees or heavy cloud usage. Consider dual-WAN setup (FTTP primary + 5G backup) for business continuity.
Choose leased line if: Multi-site business needing reliable inter-office connectivity, business where 1-hour downtime costs £1,000+ revenue, hosting on-premise servers requiring public access, guaranteed symmetric speeds non-negotiable, enterprise SLA required. Only justified if connectivity downtime genuinely costs your business £400-600/month+ in lost revenue or opportunity cost.
We'll assess your business requirements and recommend the right connectivity technology based on your usage, budget, and growth plans.
Get Recommendation →Business upload needs, cloud backup speeds, video conferencing bandwidth, VoIP requirements, and symmetric vs asymmetric speeds.
Download vs upload usage: Consumer internet (streaming Netflix, browsing websites) = 90% download, 10% upload. Business internet (cloud apps, video calls, file sharing) = 40% download, 60% upload. Residential broadband optimized for download (80Mbps down / 20Mbps up). Business needs balanced or symmetric speeds (300Mbps down / 300Mbps up).
Common upload bottlenecks: Cloud backup taking 8 hours overnight instead of 2 hours. Video calls freezing when multiple staff join (upload maxed out). Email with large attachments taking 5 minutes to send. Cloud-based accounting software laggy when saving invoices. All caused by insufficient upload bandwidth - 20Mbps upload shared across 15 users = 1.3Mbps per user (too slow for modern workflows).
Upload-heavy business activities: Cloud backups (sending data to cloud storage), video conferencing (sending your video/audio to others), VoIP calls (sending voice data), uploading files to clients/suppliers, cloud application saves (CRM, accounting, design software auto-saving to cloud), CCTV uploading to cloud storage, remote desktop (sending screen updates to remote workers).
Email & web browsing: 1-2Mbps per user sufficient. Basic office work (sending emails, browsing websites, online banking) very low bandwidth. 10 users × 2Mbps = 20Mbps total needed. Even basic FTTC 50/10Mbps package adequate for simple email/web use. Upload need minimal unless sending large email attachments frequently.
Cloud applications (Office 365, cloud ERP): 3-5Mbps per active user. Example: accountant using Xero needs 4Mbps download + 4Mbps upload for responsive performance. 20 staff on cloud apps = 80Mbps download + 80Mbps upload minimum. FTTC 80/20Mbps insufficient (only 1Mbps upload per user - laggy experience). Need FTTP 100/100Mbps minimum for smooth cloud app performance.
Video conferencing (Teams, Zoom): 2-4Mbps per video call (both download AND upload). 10-person team meeting = 10 callers × 3Mbps upload = 30Mbps upload needed. FTTC 80/20Mbps = struggles with 7+ simultaneous callers. FTTP 300/300Mbps = handles 100+ callers easily. HD video calls (1080p) need 5-8Mbps each - calculate users × 6Mbps for sizing.
Backup time calculation: Uploading 100GB nightly backup on 20Mbps upload = 11 hours (2.5MB/second × 40,000 seconds). Same backup on 300Mbps upload = 44 minutes (37.5MB/second × 2,667 seconds). Faster upload = backup completes before staff arrive next morning. Slow upload = backup still running during business hours, consuming bandwidth needed for productive work.
Incremental vs full backups: Daily incremental backups (only changed files) typically 5-20GB. Weekly full backup (entire dataset) 100-500GB. 20Mbps upload handles 20GB incremental (2.2 hours overnight) but struggles with 500GB full backup (56 hours - takes entire weekend). 300Mbps upload: 20GB = 9 minutes, 500GB = 3.7 hours (completes Friday night to Saturday morning).
Real-time sync (OneDrive, Dropbox): Files auto-uploading throughout day. Marketing team saving 500MB video file to OneDrive: 20Mbps upload = 3.3 minutes (blocks their PC while uploading). 300Mbps upload = 13 seconds (barely noticeable). Fast upload improves staff productivity - no waiting for files to sync before continuing work.
Per-call bandwidth: Standard VoIP call uses 80-100kbps (0.1Mbps) upload + 80-100kbps download. 10 simultaneous calls = 1Mbps upload + 1Mbps download. HD voice (wideband audio) uses 150kbps per direction = 1.5Mbps for 10 calls. VoIP bandwidth minimal BUT quality highly sensitive to congestion - dedicate bandwidth using QoS (Quality of Service) router settings.
Jitter and latency impact: VoIP needs consistent bandwidth (not just fast speeds). 50Mbps connection with variable latency (jitter) = choppy calls. 30Mbps connection with stable latency = perfect call quality. Upload speed matters less than upload stability for VoIP. Business broadband (20:1 contention) gives stable upload. Residential broadband (50:1 contention) = variable upload = poor VoIP quality.
Concurrent usage impact: VoIP alone needs minimal bandwidth (10 calls = 1.5Mbps). Problem: large file upload consuming all bandwidth (80Mbps file upload + 1.5Mbps VoIP on 20Mbps upload connection = calls fail). Solution: QoS prioritization - router reserves 2Mbps upload for VoIP, remaining 18Mbps available for other traffic. Configure QoS or upgrade to FTTP 300/300Mbps where VoIP impact negligible.
Asymmetric (FTTC): Download much faster than upload. Example: 80Mbps download / 20Mbps upload. Designed for consumer use (downloading content, streaming video). Problematic for business (uploading files, video calls, cloud apps all need upload bandwidth). Only acceptable for very small offices (under 5 users) doing basic email/web browsing.
Symmetric (FTTP, leased line): Upload equals download. Example: 300Mbps download / 300Mbps upload. Designed for business use. Handles cloud-heavy workflows, video conferencing, real-time collaboration. Premium costs £10-20/month more than asymmetric BUT eliminates upload bottlenecks worth £100s/month in staff productivity.
When symmetric justified: Cloud-based business (Office 365, cloud accounting, cloud CRM), video-heavy business (regular Teams meetings, client video calls), creative business (uploading large design files, video editing), multi-site business (uploading to head office servers), any business where upload bottlenecks costing 30+ minutes daily staff time (30 min × £15/hour × 20 staff × 260 days = £39,000/year lost to slow uploads - £600/year FTTP upgrade obvious choice).
Formula: (Number of users × average usage per user) + overhead buffer. Example office: 15 users, cloud-based (5Mbps/user), 5 concurrent video calls (3Mbps each). Download: (15 × 5) + (5 × 3) = 90Mbps. Upload: (15 × 5) + (5 × 3) = 90Mbps. Add 30% buffer for spikes = 120Mbps download/upload needed. FTTP 150/150Mbps or 300/300Mbps appropriate.
Peak vs average usage: Average usage may be 50Mbps but peak usage (10am Monday when everyone logging in + downloading emails + joining team meeting) hits 150Mbps. Size connection for peak usage not average. Undersized connection = slow performance exactly when staff need it most (peak productivity hours). Oversized connection wastes money. Monitor actual usage first month then right-size.
Growth planning: Bandwidth needs grow 20-30%/year typically (more cloud apps, higher quality video, larger files). Buy connection with 50% headroom for growth. Choosing 100Mbps when currently need 80Mbps = upgrade needed in 12 months. Choosing 200Mbps when need 80Mbps = good for 3+ years. Connection upgrades take 4-8 weeks (can't instant-upgrade when maxed out). Plan ahead or suffer slow performance waiting for upgrade.
Choosing residential broadband: "300Mbps for £30/month!" - looks great compared to business 100Mbps for £50/month. Problem: 300Mbps download / 30Mbps upload (asymmetric), 50:1 contention (shared with 50 homes), no SLA, consumer T&Cs (can be terminated for business use). Business 100/100Mbps actually faster for upload-heavy work + reliable + protected.
Ignoring upload requirements: "80Mbps is loads!" - looking only at download speed. Upload 20Mbps = 1.3Mbps per user in 15-person office. Video calls fail, cloud saves lag, backups incomplete by morning. Always check upload speed and calculate per-user upload (total upload ÷ number of users). Need minimum 2Mbps upload per user for modern workflows.
Not testing before committing: Sales demo on provider's WiFi showing 300Mbps speeds. Your office gets 50Mbps actual (poor signal, cabinet distance, old internal wiring). Ask for try-before-buy or money-back guarantee. Test actual speeds at your premises before signing 36-month contract. Wired speed test (ethernet cable to router) shows true connection speed, WiFi test shows WiFi performance (often WiFi bottleneck not broadband speed).
We'll assess your business usage and recommend the right speed tier based on number of users, cloud applications, and upload requirements.
Get Assessment →Static vs dynamic IPs, remote access requirements, server hosting, CCTV systems, costs (£5-10/month), and when you actually need one.
Static IP: Fixed internet address that never changes. Your business gets assigned 82.45.123.45 and keeps this address permanently. Like having a fixed postal address - people/systems can always find you at the same location. Essential for remote access, hosting servers, CCTV cloud upload, VPN connections.
Dynamic IP: Internet address changes regularly (every few days or weeks when router reboots). Your business gets different address each time: today 82.45.123.45, next week 82.45.200.12, following week 82.45.98.203. Like changing postal address monthly - impossible for remote systems to reliably connect to you.
How it works: Every device connecting to internet needs IP address (like phone number for internet). Your router gets public IP from internet provider. Static IP = same number always. Dynamic IP = provider assigns different number from pool each connection. Most residential broadband = dynamic IP (free). Business broadband can add static IP (£5-10/month).
Remote access to office systems: Accessing office computer/server from home requires knowing office IP address. Dynamic IP changes = remote access breaks every few days (must reconfigure connection each time). Static IP = configure once, works forever. Remote desktop, file server access, cloud accounting access all need static IP for reliability.
Hosting on-premise servers: Running email server, website server, database server at office = need static IP for external access. Customers/clients connecting to your server need consistent address. Dynamic IP = your website offline every time IP changes (few days to few weeks). Static IP = uninterrupted service. Cloud hosting eliminates need (server in cloud has static IP, you don't need one at office).
CCTV cloud upload: Security cameras uploading to cloud storage need static IP for initial configuration and ongoing access. Dynamic IP = reconfigure cameras every IP change (cameras can't find upload destination). Modern cloud CCTV services use outbound connections (cameras call home to cloud) eliminating static IP need - check with CCTV provider before ordering static IP.
Cloud-only businesses: Using Office 365, cloud accounting (Xero, QuickBooks Online), cloud CRM (Salesforce), cloud file storage (Dropbox, OneDrive) = no static IP needed. All systems hosted in cloud with their own static IPs. You're connecting OUT to cloud services (outbound connection works fine with dynamic IP). Static IP only needed for services connecting IN to you (inbound connections).
VPN with dynamic DNS: Some VPN systems support dynamic DNS (automatically updates when your IP changes). Router updates DNS record each IP change, VPN clients use DNS name instead of IP address. Example: office.yourcompany.dyndns.org always points to current IP even if changes daily. Check if VPN supports DDNS before paying £120/year for static IP you don't need.
Standard internet use: Browsing websites, sending emails, making VoIP calls, using cloud applications = all outbound connections. Dynamic IP perfect for these. 80% of businesses don't need static IP but pay for it anyway (£10/month × unnecessary = £120/year waste). Only order static IP if specific system/service requires it - ask IT provider first.
Single static IP: £5-10/month typical cost. One fixed address for your router/office. Sufficient for most business needs (remote access, VPN, single server hosting). Example pricing: BT £5/month, TalkTalk £7/month, Virgin £10/month. Often bundled free on premium business broadband packages (check before paying separately).
Multiple static IPs (IP block): £15-30/month for 5-16 IP addresses. Needed if hosting multiple public servers (web server, email server, FTP server each needing own IP). Most businesses don't need this - single static IP with port forwarding handles multiple services. Only order IP block if networking specialist confirms requirement.
IPv4 vs IPv6: IPv4 = traditional IP format (82.45.123.45). IPv6 = newer format (2001:0db8:85a3:0000:0000:8a2e:0370:7334). IPv4 addresses scarce (running out globally) = cost increasing. IPv6 addresses abundant = usually free. Problem: many old systems don't support IPv6 yet. Get both if available (IPv4 for compatibility, IPv6 for future). Most providers include IPv6 free, charge for IPv4.
Increased attack surface: Static IP = hackers can target your business consistently. Dynamic IP = target moves regularly (harder to attack). Static IP without firewall = constant port scanning, brute force attempts, vulnerability probes. Essential: business-grade firewall (£100-300) mandatory with static IP. Never use static IP with basic consumer router (inadequate security).
Port forwarding risks: Static IP enables port forwarding (external access to internal servers). Each forwarded port = potential security hole if server compromised. Only forward essential ports. Close unused ports. Update server software regularly (unpatched servers on public IP = hacked within hours). Consider VPN instead of port forwarding (more secure, encrypted access).
Firewall configuration: Static IP requires proper firewall rules. Allow: VPN (1194), remote desktop (3389), web server (443) only from known IPs if possible. Block: all other inbound traffic. Enable logging (track connection attempts). Review logs monthly (identify attack patterns). Misconfigured firewall on static IP = business network exposed to internet (ransomware, data theft risk high).
Dynamic DNS (DDNS): Free/cheap service updating DNS record when IP changes. Router detects IP change, updates DynDNS automatically. You connect using youroffice.dyndns.org (always points to current IP). Works well for VPN, remote desktop, camera systems. Limitations: 5-10 minute lag during IP change (brief outage), not suitable for high-uptime requirements (99.9%+ needed). Cost: free (basic) to £25/year (premium).
Cloud-based solutions: Instead of hosting server at office (needs static IP), host in cloud (AWS, Azure, cloud provider handles static IP). Remote access via cloud instead of direct office access. Example: cloud-hosted remote desktop server (users connect to cloud, cloud connects to office via VPN). More expensive (£50-200/month cloud hosting) but more reliable and secure than office-based static IP setup.
Zero Trust / SD-WAN: Modern approach eliminating static IP need. Devices connect outbound to cloud orchestrator, orchestrator brokers connections. No inbound connections to office = no static IP required. Works for remote access, multi-site connectivity, CCTV upload. Higher initial cost (£50-100/month SD-WAN service) but eliminates £10/month static IP + improved security + better management.
Ordering process: Contact broadband provider, request static IP add-on. Provisioning takes 1-5 working days (IP assigned remotely, no engineer visit). Provider emails your new static IP address + subnet mask + gateway details. You configure router with static IP settings (replacing dynamic DHCP). Most business routers auto-configure when provider assigns static IP (plug-and-play).
Router configuration: Log into router admin panel, navigate to WAN/Internet settings. Change from DHCP (dynamic) to Static IP. Enter: IP address (provided by ISP), subnet mask (usually 255.255.255.0), gateway (usually x.x.x.1), DNS servers (ISP provides). Save settings, router reboots with static IP. Test: visit whatismyip.com, confirm shows your static IP (not changing on reboot).
DNS records: Point domain name to static IP for services. Example: hosting email server on 82.45.123.45, create MX record pointing mail.company.com to 82.45.123.45. Web server: A record pointing www.company.com to static IP. Changes take 4-48 hours to propagate (DNS caching). Use low TTL (300 seconds) during migration for faster updates if problems occur.
We'll assess your requirements and recommend whether static IP necessary or if cloud-based alternatives better suit your needs.
Get Advice →Shared bandwidth explained, peak-time slowdowns, business (20:1) vs residential (50:1) ratios, and uncontended leased lines (1:1).
Shared bandwidth concept: Internet providers don't give every customer dedicated connection to internet backbone. Instead, multiple customers share connection infrastructure. Contention ratio = number of customers sharing same bandwidth pool. 20:1 means your business shares with 19 others. 50:1 means sharing with 49 others. Lower ratio = less sharing = better performance.
How it works: Street cabinet has 1Gbps connection to internet exchange. With 50:1 contention, provider sells this to 50 homes/businesses at 80Mbps each (4,000Mbps total if everyone maxed out simultaneously). Reality: not everyone uses internet at once. Average usage: 10-20% of sold capacity. Provider gambles on statistical usage patterns - works well most of time, fails during peak hours when everyone online.
Impact on your business: 80Mbps broadband on 50:1 contention might deliver 80Mbps at 3am (nobody else online) but only 20Mbps at 10am Monday (everyone using internet). Speed advertised = maximum possible, not guaranteed. Contention ratio determines real-world performance during business hours. Business broadband 20:1 = better peak-hour performance than residential 50:1.
Residential broadband 50:1: Designed for consumer use (evenings/weekends peak usage). Daytime performance good (households at work/school, low usage 9am-5pm). Evening performance degrades (6pm-11pm everyone streaming Netflix, gaming, browsing). Cost: £20-35/month for 50-100Mbps. Fine for very small businesses (1-3 people) with flexible working hours avoiding peak times.
Business broadband 20:1: Designed for business use (daytime peak usage). Daytime performance stable (9am-5pm guaranteed bandwidth when businesses need it). Evening performance less relevant (most businesses closed). Cost: £35-60/month for 50-100Mbps. Worth extra £15/month for businesses relying on stable daytime connectivity.
Real-world example: Residential 80Mbps (50:1 contention): 3am = 78Mbps actual, 10am = 35Mbps actual, 2pm = 45Mbps actual, 8pm = 25Mbps actual. Business 80Mbps (20:1 contention): 3am = 78Mbps actual, 10am = 65Mbps actual, 2pm = 62Mbps actual, 8pm = 70Mbps actual. Business contract delivers 2x better performance during working hours despite same headline speed.
Dedicated bandwidth: Leased line provides uncontended 1:1 connection - your business gets dedicated circuit not shared with anyone. 100Mbps leased line delivers 100Mbps 24/7/365 regardless of time or network load. No contention, no slowdowns, no peak hour degradation. Guaranteed symmetric speeds (100Mbps upload + 100Mbps download always).
Cost comparison: Standard FTTP 100Mbps (20:1) = £45/month. Leased line 100Mbps (1:1) = £400-600/month. 10-13x cost premium for uncontended bandwidth. Worth it for mission-critical businesses (e-commerce sites losing £1,000/hour during outages, financial trading, medical facilities). Overkill for most small businesses where occasional slowdown acceptable.
When justified: Multi-site business needing reliable inter-office connectivity (head office to 5 branches), data centre hosting customer-facing services, business where 30-minute outage costs £500+ in lost revenue/reputation. For £350/month leased line premium over standard broadband, calculate: do speed/reliability issues currently cost £4,200/year in lost productivity? If no, stick with contended broadband.
Identifying peak-time slowdowns: Run speed test (speedtest.net) at different times: 7am, 10am, 1pm, 4pm, 7pm, 10pm. Consistent speed = good contention management. Variable speed (50% drop during peak) = oversubscribed connection. Document results over 1 week. If business-hours speed consistently 40-50% below advertised, complain to provider or switch.
Common peak hour symptoms: Video calls freezing 10am-2pm (peak contention period). Cloud applications loading slowly mid-afternoon. File uploads taking 3x longer during business hours vs overnight. VoIP calls dropping/choppy during lunch hour (everyone online simultaneously). These symptoms indicate contention ratio issue not bandwidth shortage.
Solutions: Upgrade to business-grade contract (50:1 → 20:1 improves peak performance). Upgrade to FTTP where available (higher capacity infrastructure = better contention handling). Schedule bandwidth-heavy tasks off-peak (large backups midnight, not midday). Split critical systems onto separate connection (primary FTTP for general use + secondary 4G for VoIP only = guaranteed VoIP bandwidth even when FTTP congested).
Finding contention ratio: Most providers don't advertise contention ratio prominently. Check: product name ("business broadband" usually 20:1, "standard broadband" usually 50:1), terms & conditions (buried in small print), call sales team and ask directly. If provider refuses to disclose contention ratio, assume worst (50:1 or higher). Reputable business providers transparent about contention (good sign).
Misleading marketing: "Up to 100Mbps" technically accurate even if only delivers 30Mbps peak hours. "Ultrafast broadband" says nothing about contention. "Business-grade" doesn't guarantee 20:1 (some providers use 30:1 or 40:1 for "business" packages). Always ask: "What is guaranteed minimum speed during peak business hours?" and "What contention ratio?" Don't accept vague answers.
Trial periods: Request 30-day money-back guarantee. Test speed during peak business hours before committing to 24-month contract. Document actual speeds (run tests 9am-5pm for 2 weeks). If consistently below expectations, return within trial period and try different provider. Better to spend 2 weeks testing than stuck 24 months with poor performance.
QoS (Quality of Service) configuration: Business routers support QoS - prioritize critical traffic over non-critical. Example: VoIP gets 3Mbps guaranteed (highest priority), video conferencing gets 10Mbps (medium priority), general browsing gets remaining bandwidth (low priority). During congestion, router ensures VoIP works perfectly even if web browsing slows. Requires business-grade router (£150-400) and technical setup.
Bandwidth scheduling: Schedule non-essential bandwidth usage off-peak. Cloud backups run midnight-6am instead of 2pm. Large file transfers scheduled 7pm (after business hours). Software updates overnight instead of mid-morning. Leaves peak-hour bandwidth available for staff productivity (cloud apps, email, calls). Simple scheduling saves £30/month broadband upgrade costs.
Dual-WAN setup: Two separate internet connections from different providers. Primary FTTP (general use) + secondary 4G/5G (automatic failover). Load balancing: split traffic across both connections (50% via FTTP, 50% via 4G). Effective bandwidth doubles (80Mbps FTTP + 50Mbps 4G = 130Mbps total). Cost: £45 FTTP + £35 4G = £80/month for better performance than single £80/month leased line (though without same reliability guarantees).
We'll test your actual peak-hour performance and recommend solutions - whether that's better contention ratio, dual-WAN, or QoS configuration.
Get Help →Survey fees (£50-150), engineer visits (£0-100), civil works (£500-2,000+), lead times (2-12 weeks), and waived installation deals.
Installation cost: £0-100 typically. Most providers waive installation fee on 12-24 month contracts. New line activation (no previous broadband): £50-100 engineer visit charge. Existing line reactivation (previous broadband at address): usually free (remote activation, no engineer needed). Promotional periods: completely free installation common (check provider websites).
Timeline: 10-15 working days from order to activation. Breakdown: Order placed → 2-3 days provider processes → 5-7 days Openreach schedules engineer → Engineer visit (2-4 hours) → Service activated. Can be faster (5-7 days) if infrastructure ready and slots available. Delays possible (20+ days) in rural areas or during peak demand periods (September, January).
What's included: Engineer activates line at cabinet (street-side work), tests signal to premises, installs master socket if needed, provides modem/router, connects and tests connection. Internal wiring usually customer responsibility (ethernet cables, WiFi setup). Engineer won't move furniture, drill walls, or run cables - just basic connection from BT socket to router.
Installation cost: £100-300 standard charge. Often waived on 24-36 month contracts. Premium for difficult installs (£300-500 if complex routing needed). Includes: fibre cable run from street cabinet to premises, internal termination point installation, Optical Network Terminal (ONT) unit, router connection and testing. Much more invasive than FTTC (physical cable installation vs remote activation).
Timeline: 3-6 weeks if fibre available at cabinet, 8-12 weeks if new build required. Breakdown: Order → Survey (1-2 weeks to schedule, 1 hour onsite) → Design (1 week route planning) → Installation (2-4 weeks to schedule, 4-8 hours onsite) → Testing and handover. Survey determines feasibility and installation method. Some addresses impossible/uneconomical (rural locations, listed buildings with restrictions).
Installation process: Survey engineer checks route from cabinet to premises. Installation day: Fibre cable run (usually overhead via telegraph poles OR underground via ducts). External cable termination at building wall. Internal cable route (surface-mounted trunking OR hidden in walls if customer arranges). ONT installation (wall-mounted box where fibre terminates). Router connection. Testing. Takes 4-8 hours total (schedule full day).
When needed: Fibre run across car park (requires trenching), through thick stone walls (drilling), underground duct installation (no overhead poles available), listed building restrictions (specific installation methods required), multi-floor buildings (internal riser ducting). Survey identifies civil works requirement - get written quote before proceeding.
Cost range: £500-2,000 typical, can exceed £5,000 for complex jobs. Example costs: Simple trench 10m across tarmac = £500-800. Underground duct 50m across car park = £1,200-1,800. Core drilling through 3 walls = £300-600. Scaffolding for high building access = £400-800. Internal riser duct 4 floors = £1,000-1,500. Always get multiple quotes (Openreach, provider, independent contractor).
Who pays: Standard rule: customer pays civil works costs upfront. Some providers absorb on long contracts (36-60 months). Negotiate: "Will you waive £1,500 civil works if I sign 48-month contract?" Sometimes works (provider recoups over contract term). Alternative: delay installation until fibre naturally expands to your area (avoid civil works entirely but may wait 1-2 years).
Site survey: Required for FTTP, leased lines, complex installs. Engineer visits to assess route feasibility. Checks: cabinet to premises distance, obstacles (roads, railways, private land), existing duct availability, internal routing options, power requirements. Takes 30-90 minutes. Provides: feasibility report, installation method, cost estimate, timeline.
Survey fees: £50-150 for FTTP survey (usually refunded if you proceed with order). £200-500 for leased line survey (often refunded on installation). Free surveys during promotional periods or on enterprise contracts. Get survey before committing to office lease - discovering £2,000 civil works needed after signing lease = unpleasant surprise.
Survey outcomes: Best case: Standard installation, no civil works, proceed immediately. Medium case: Civil works required, quoted £500-1,500, decide if acceptable. Worst case: Installation impossible/uneconomical (£5,000+ cost), need alternative (5G broadband, wait for natural fibre expansion, relocate office). Survey de-risks before committing to property/contract.
Lead time by technology: FTTC reactivation = 5-10 days. FTTC new line = 10-20 days. FTTP standard = 3-6 weeks. FTTP with civil works = 8-12 weeks. Leased line = 60-90 days. 5G broadband = 0 days (instant). Plan accordingly when moving offices - order FTTP 2 months before move-in date to ensure ready on day 1.
Delays and contingencies: Engineer no-show (reschedule adds 1-2 weeks). Survey identifies unexpected issues (adds 2-4 weeks). Wayleave permissions needed (crossing private land adds 4-8 weeks). Council permits required (road crossing adds 6-12 weeks). Always add 30% buffer to quoted timeline. Critical office move? Order broadband 3 months early, accept temporary overlap costs (paying old + new for 1 month) to guarantee connectivity.
Temporary solutions during installation: 5G broadband (plug-and-play while waiting for fibre). Mobile hotspot (4G tethering for skeleton crew). Temporary FTTC (cheaper quick install, upgrade to FTTP when ready). Work from home (staff remote during 2-week delay). Co-working space rental (£20-40/day/desk while waiting). Budget £500-1,000 contingency for temporary connectivity if main install delayed.
When offered: Promotional periods (September, January), new customer acquisition campaigns, 24+ month contracts, business broadband packages (not residential), competitive pressure (provider matching competitor offers). Ask: "Can you waive installation fee?" Often works even if not advertised. Providers prefer waiving £200 installation to losing £50/month × 24 months = £1,200 contract.
Contract trade-off: Free installation usually requires 24-36 month contract. Calculate: £200 installation saving ÷ 12 months extra commitment = £16.67/month saved. Worth it if you're staying at premises 24+ months anyway. Not worth it if might relocate within 18 months (early termination fees £300-500 exceed installation savings). Match contract length to office lease length.
What's NOT usually waived: Civil works costs (£500-2,000+) rarely waived except on multi-year enterprise deals. Non-standard equipment (mesh WiFi systems, business routers) usually paid separately. Additional wiring/sockets beyond standard install = customer cost. Survey fees sometimes refundable on order but not waived upfront. Static IP setup fees (£25-50) rarely waived. Realistic expectation: standard installation free, everything else paid.
Access requirements: Someone onsite full installation duration (4-8 hours for FTTP). Keys to all areas (engineer needs roof access for overhead cables, basement for underground entry). Clear route for cable run (move furniture, remove obstacles). Power socket near termination point. Parking space for engineer van. Mobile number for engineer to call (confirm before appointment day).
Decision points during install: Cable entry point (where fibre enters building - usually near BT master socket but flexible). Internal cable route (surface trunking visible OR hidden in walls if you drill). ONT location (wall-mounted box - needs power socket nearby). Router placement (near ONT unless you run long ethernet). Make decisions before engineer arrives (speeds up install, avoids suboptimal choices made under pressure).
Post-installation tasks: Test connection (speed test, browse websites, test email). Configure WiFi (change default SSID/password). Connect devices (PCs, phones, printers). Configure VoIP if applicable. Test phone system. Update staff on new WiFi password. Document setup (router admin password, static IP if applicable, provider support number). Schedule WiFi optimization if needed (mesh network, access point placement).
We'll coordinate surveys, negotiate waived installation fees, and ensure broadband ready on move-in day. No unpleasant surprises.
Get Help →99.9% uptime meaning (8.76 hours downtime/year), compensation calculations, fix-time guarantees (4-24 hours), and downtime cost analysis.
99% uptime: Sounds good but equals 87.6 hours downtime per year (3.65 days total). That's 7.3 hours/month average downtime. For business operating 250 days/year, that's potentially 21 minutes downtime per working day. Unacceptable for most businesses. Consumer broadband typically 95-99% uptime (18-43 hours down/year).
99.5% uptime: 43.8 hours downtime per year (1.8 days total). Equals 3.65 hours/month. Still problematic - that's half a working day monthly. Standard business broadband typically offers 99-99.5% uptime. Acceptable for very small businesses (1-5 people) with flexible schedules who can work around occasional outages.
99.9% uptime: 8.76 hours downtime per year (just over 1 day total). Equals 43 minutes/month. Premium business broadband target. Acceptable for most SMEs. Realistically: 2-3 outages yearly lasting 2-4 hours each. Not perfect but manageable with backup plans (mobile hotspot, work from home during outage).
99.99% uptime: 52 minutes downtime per year total. Equals 4.3 minutes/month. Enterprise-grade SLA. Leased line territory (costs £400-1,000/month). Realistically: 1 outage yearly lasting 30-60 minutes. Essential for businesses where every hour of downtime costs £1,000+ in lost revenue (e-commerce, call centres, financial services).
Consumer/basic business (no fix time): "We'll fix it as soon as possible" = could be 24 hours, could be 7 days. No guarantees, no penalties for delays. Typical repair: 24-72 hours if simple (cabinet issue), 3-7 days if complex (requires engineer callout, parts ordering). Weekend/evening faults often wait until next business day for attention.
Standard business (24-48 hour fix time): Fault reported, provider targets fix within 24-48 hours. Not guaranteed - just a target. Typical cost: included in standard business package (no extra fee). Realistically: simple faults fixed 12-24 hours, complex faults 48-72 hours. Weekends excluded from SLA (fault Friday 5pm might not be fixed until Tuesday).
Enhanced business (8-12 hour fix time): Guaranteed fix within 8-12 business hours or compensation paid. Extra cost: £10-25/month premium. Includes: priority engineer dispatch, escalation to senior technical team, out-of-hours contact number. Worth it for businesses moderately dependent on connectivity (12 hours down = £500-1,000 lost productivity acceptable but not ideal).
Premium/leased line (4-6 hour fix time): Guaranteed fix within 4-6 hours including weekends/evenings. Part of enterprise packages (£300-1,000/month total cost). Includes: dedicated account manager, 24/7 phone support, engineer on standby. Financial penalties for breach (£100-500/hour compensation). Only justified for businesses where 6+ hour outage costs £2,000+ in immediate lost revenue.
Typical compensation structure: 1 day service credit per 1 hour of downtime beyond SLA. Example: £50/month service, 99.9% SLA allows 43 minutes/month downtime. Actual downtime 5 hours in a month = 4.28 hours breach. Compensation: 4.28 days × (£50 ÷ 30 days) = £7.13 credit. Minimal compensation relative to business impact.
Maximum compensation caps: Usually capped at 100% of monthly fee (one month free service). 20-hour outage on £50/month package = maximum £50 compensation even though business lost £2,000 in revenue. SLA compensation covers provider's service cost NOT your business losses. Providers explicitly disclaim liability for consequential damages (lost revenue, lost customers, reputation damage).
Claiming compensation: Not automatic - must submit claim with fault reference number. Deadline typically 30-90 days from incident. Evidence required: fault report confirmation, duration logs, impact statement. Processing time: 4-8 weeks for credit to appear on bill. Small businesses often don't bother claiming (£5-20 credit not worth admin hassle). Set reminder to claim or lose entitlement.
Revenue loss calculation: E-commerce business £50,000/month revenue ÷ 30 days = £1,667/day ÷ 8 hours = £208/hour revenue. 4-hour outage = £833 lost revenue. Can staff do alternative work during outage? If yes, reduce impact 50% (£416 actual loss). Can sales be recovered later? If yes, reduce further 30% (£291 final loss). Compare against SLA compensation (probably £10-20) - massive gap.
Productivity loss calculation: Office 15 staff @ £15/hour average = £225/hour total payroll cost. 4-hour outage = £900 payroll spent with zero productivity. Can staff do offline work (paperwork, phone calls)? If 50% productive offline, actual loss = £450. Realistic: complete outage 2-3 times yearly × £450 each = £900-1,350 annual productivity cost from downtime. Compare against SLA upgrade cost (£25/month = £300/year) - upgrade justified.
Customer impact calculation: Call centre handling 200 calls/day. 4-hour outage = 100 missed calls. Recovery rate 60% (customers call back) = 40 lost calls permanently. Value per call £50 average = £2,000 immediate revenue loss. Reputation damage harder to quantify but customers switching to competitors after poor service experience = ongoing revenue impact. Businesses with direct customer-facing connectivity needs can't afford frequent outages.
Standard SLA upgrade: £10-25/month extra for enhanced SLA (99.9% uptime, 8-12 hour fix time, 24/7 support). Includes: faster response, dedicated support team, proactive monitoring, priority engineer dispatch. ROI calculation: £20/month = £240/year. If prevents one 8-hour outage worth £1,000 productivity loss, paid for itself 4x over. Worth it for businesses with 10+ staff or customer-facing operations.
Managed service add-ons: £50-150/month for comprehensive managed connectivity. Includes: enhanced SLA + proactive monitoring + remote troubleshooting + router management + security patches + monthly reporting. Best for businesses without in-house IT staff. Provider monitors connection 24/7, often fixes issues before you notice. Expensive but cheaper than hiring IT staff (£50/month vs £2,000/month employee).
Dual-supplier redundancy: Two separate connections from different providers (automatic failover if primary fails). Cost: £45 primary FTTP + £35 secondary 4G = £80/month total. Effective uptime 99.99%+ (both fail simultaneously extremely rare). More reliable than single expensive leased line. Best for businesses where uptime critical but budget doesn't stretch to £500/month leased line.
Exclusions from SLA: Planned maintenance (usually 2am-6am, provider gives 7 days notice). Customer equipment failure (your router dies - not provider fault). Internal wiring issues (office network problems). Power outages (your office loses power - connection works but you can't use it). DDoS attacks on your systems. Third-party network issues (e.g. Google services down - your connection fine but websites unreachable). Read exclusions carefully - SLA narrower than it appears.
Force majeure events: Natural disasters, flooding, fires, vandalism to infrastructure, strikes, terrorism, government action. Provider not liable for compensation during force majeure. Example: flood damages street cabinet, 50 businesses lose connectivity for 3 days. SLA compensation: £0 (force majeure). Businesses lose thousands but no recourse. Insurance gap: business interruption insurance might not cover infrastructure failures outside your premises.
Proving SLA breach: Burden of proof on customer. Provider claims 30-minute outage, you experienced 8 hours. Without monitoring logs proving duration, provider's data prevails. Solution: implement independent monitoring (Pingdom, UptimeRobot - £10-20/month) generating timestamped logs. When claiming compensation, provide third-party evidence of outage duration. Significantly increases successful claim rate.
Low dependency businesses: 1-5 staff, basic email/web use, can work offline during outages. Standard SLA sufficient (99-99.5% uptime, 24-48 hour fix). Cost: £0 extra. Acceptable: 2-3 outages yearly lasting 4-8 hours each. Mitigation: mobile hotspot backup (£30/month 4G SIM unlimited data) provides emergency connectivity at £360/year vs £240-300/year enhanced SLA cost.
Medium dependency businesses: 10-20 staff, cloud-based operations, VoIP phone system. Enhanced SLA recommended (99.9% uptime, 8-12 hour fix, 24/7 support). Cost: £15-25/month extra. Justification: 12-hour outage costs £1,500 in lost productivity (20 staff × £15/hour × 5 hours affected = £1,500). Enhanced SLA £300/year prevents most extended outages - ROI positive if prevents just one long outage annually.
High dependency businesses: Customer-facing operations, e-commerce, financial services, call centres. Premium SLA essential (99.99% uptime, 4-6 hour fix). Cost: £300-1,000/month (leased line or dual-provider setup). Justification: 1-hour outage costs £2,000+ in lost revenue. Spending £500/month on connectivity insurance (robust SLA) cheaper than £2,000 loss from single outage. Non-negotiable for mission-critical connectivity.
We'll assess your business dependency on connectivity and recommend the right SLA level - avoiding both under-protection and overpaying for unnecessary guarantees.
Get Assessment →100kbps per call, jitter under 30ms, latency under 150ms, QoS settings, codec selection (G.711 vs G.729), and call quality troubleshooting.
Standard voice call (G.711 codec): 87kbps bandwidth per direction (87kbps upload + 87kbps download = 174kbps total per call). 10 concurrent calls = 870kbps (0.87Mbps) upload + 870kbps download. Minimal bandwidth BUT consistency critical. Variable connection = choppy calls even with adequate average speed. G.711 uncompressed = best quality, higher bandwidth.
Compressed voice (G.729 codec): 31kbps bandwidth per direction (31kbps upload + 31kbps download = 62kbps total per call). 10 concurrent calls = 310kbps (0.31Mbps) each direction. 3x less bandwidth than G.711 BUT slightly lower call quality (compressed audio). Use when bandwidth constrained - acceptable quality for most business calls. Not recommended for customer-facing call centres (quality matters).
HD voice/wideband (G.722 codec): 64-100kbps per direction. Higher quality audio (fuller frequency range, clearer speech). Premium VoIP systems support HD voice. Requires both parties on HD-capable systems. Often not worth extra bandwidth - standard G.711 sufficient for business calls. Reserve HD for conference call systems where audio quality critical.
Latency (delay): Time for voice data to travel from speaker to listener. Target: under 150ms one-way. Acceptable: 150-300ms (noticeable delay but usable). Unacceptable: over 300ms (conversation difficult, people talk over each other). Satellite internet = 500-700ms latency (terrible for VoIP). FTTC/FTTP typically 5-30ms (excellent). 5G variable 20-80ms (usually acceptable). Test latency: ping google.com, check average response time.
Jitter (variation in delay): Inconsistent packet arrival timing. Target: under 30ms jitter. High jitter symptoms: choppy audio, words cutting out, robotic sound. Causes: network congestion, WiFi interference, poor quality router. Solution: QoS (Quality of Service) prioritization, wired connection (not WiFi for VoIP phones), business broadband (lower contention = stable latency). Jitter more important than latency for call quality.
Packet loss: Voice data packets fail to arrive. Target: under 1% packet loss. 1-3% packet loss = occasional audio glitches (tolerable). 3-5% = frequent dropouts (poor quality). Over 5% = calls unusable. Causes: overloaded connection, faulty equipment, line quality issues. Test: run ping test with 100 packets (ping -n 100 google.com), check % loss. If consistently over 2%, investigate with provider.
Why QoS matters: Without QoS: large file download consuming 18Mbps upload on 20Mbps connection = 2Mbps left for everything else. VoIP needs 1Mbps for 10 calls but only gets 2Mbps shared with email, cloud saves = calls suffer. With QoS: router reserves 2Mbps upload exclusively for VoIP (highest priority), remaining 18Mbps available for other traffic. File downloads slow slightly BUT calls perfect quality.
Setting up QoS: Requires business-grade router (consumer routers often lack proper QoS). Configure priority levels: Highest (VoIP), Medium (video conferencing), Low (general browsing, downloads). Identify VoIP traffic by: IP address range (VoIP provider's servers), port numbers (typically UDP 5060-5090), or DSCP markings (VoIP system tags packets). Reserve 10-15% more bandwidth than calculated need (safety margin for spikes).
QoS vs bandwidth upgrade: Example: 20Mbps upload, experiencing VoIP issues during large uploads. Option A: QoS configuration (£0 cost, 2 hours setup) reserves 2Mbps for VoIP. Option B: Upgrade to 50Mbps upload (£20/month extra = £240/year). QoS solves problem free. Only upgrade bandwidth if QoS insufficient (very heavy concurrent usage). Try QoS first before paying for unnecessary speed upgrade.
Minimum connection: 5Mbps download + 2Mbps upload for 10-15 concurrent calls (with QoS). Realistically: 10Mbps download + 5Mbps upload safer (headroom for spikes). Basic FTTC 40/10Mbps adequate for small office VoIP (10 staff, 5 concurrent calls typical). Don't need ultrafast broadband just for VoIP - quality matters more than speed. 30Mbps stable connection better than 300Mbps congested connection.
Recommended connection: FTTP 100/100Mbps symmetric for VoIP-heavy businesses (call centres, customer service teams). Upload speed critical (sending your voice to caller). Asymmetric FTTC 80/20Mbps problematic for high call volumes (20Mbps upload = only 20 concurrent calls maximum before congestion). Symmetric FTTP 100/100Mbps = 100+ concurrent calls possible (plus normal internet use). Future-proof for growth.
Connection quality indicators: Business broadband (20:1 contention) better than residential (50:1) for VoIP. Dedicated upstream preferred over shared. Wired connection better than wireless. Ping test: under 30ms latency, under 20ms jitter, under 1% packet loss = VoIP-ready. Run tests during peak business hours (10am-4pm) not middle of night. Peak performance matters for business calls.
One-way audio: You hear caller but they can't hear you (or vice versa). Cause: firewall blocking VoIP ports, NAT configuration issues, SIP ALG interference (router feature that "helps" VoIP but often breaks it). Fix: Open UDP ports 5060-5090 in firewall, configure port forwarding, disable SIP ALG in router settings. Test after each change. Requires technical knowledge or IT support.
Choppy/robotic audio: Words cutting in and out, robotic sound. Cause: jitter (inconsistent packet timing), insufficient bandwidth during peak usage, WiFi interference. Fix: Check jitter (should be under 30ms), implement QoS, use wired connection for desk phones (not WiFi), upgrade to business broadband if on residential. Test connection quality with VoIP provider's diagnostic tools.
Echo/delay: Hear your own voice echoing back, long delay between speaking and being heard. Cause: high latency (over 200ms), acoustic echo (speakerphones), line echo (network issue). Fix: Check latency (ping test), use headsets instead of speakerphones, contact VoIP provider to check for line echo cancellation settings. Satellite/3G connections often unusable due to inherent latency (500ms+).
G.711 (uncompressed): 87kbps per call, best quality, highest bandwidth. Use when: adequate bandwidth available (10Mbps+ upload for 50 concurrent calls), call quality critical (sales calls, customer service), no bandwidth constraints. Most VoIP systems default to G.711. Don't change unless bandwidth problems occur. "If it ain't broke, don't fix it."
G.729 (compressed): 31kbps per call, good quality, lower bandwidth. Use when: bandwidth constrained (limited upload speed), many concurrent calls on slower connection, remote sites with poor connectivity. Trade-off: slightly lower quality but 3x more calls on same bandwidth. Acceptable for internal calls, adequate for most customer calls. Not ideal for premium customer service lines.
Mixed codec strategy: Configure VoIP system for G.711 primary, G.729 fallback. System uses best quality codec available, switches to compressed if bandwidth constrained. Best of both worlds: high quality when possible, degrades gracefully when network busy. Requires VoIP system supporting adaptive codec selection. Check with VoIP provider if supported.
Pre-deployment testing: Before committing to VoIP system, test line quality. Free tools: VoIP provider's speed test (tests latency/jitter/packet loss), DSLReports Speed Test (includes BufferBloat test showing VoIP suitability). Run tests during peak business hours over 1 week. Document results. If consistently showing: latency under 150ms, jitter under 30ms, packet loss under 1% = VoIP-ready connection.
Ongoing monitoring: VoIP quality degrades over time (network congestion increases, equipment ages). Monitor: call quality reports from VoIP system (most systems log metrics), user feedback (staff reporting quality issues), periodic speed tests. Set monthly reminder to check statistics. Early warning of degradation = fix before customers complain.
Troubleshooting workflow: Issue reported (poor call quality) → Run speed test (check latency/jitter/packet loss) → Check router utilization (bandwidth maxed out?) → Check concurrent calls (exceeded capacity?) → Test wired vs WiFi (isolation test) → Check with VoIP provider (line issue?). Systematic approach identifies root cause faster than random fixes. Document findings for future reference.
We'll test your line quality, configure QoS if needed, and recommend VoIP-optimized broadband if current connection insufficient.
Get Help →SD-WAN explained, site-to-site VPN (£50-150/month), MPLS vs internet VPN, cloud-managed networking, and connecting multiple office locations.
Business scenarios requiring multi-site: Head office + 3 branches needing shared file server access. Retail chain with central inventory/POS system accessed by 10 shops. Manufacturing with office + factory floor requiring production data sharing. Professional services (accountants, solicitors) with multiple offices sharing client databases. Any business where staff at different locations need to access same systems as if in same building.
Without proper connectivity: Each site operates independently. File sharing via email (version control nightmare). Cloud storage with constant uploads/downloads (slow, expensive data transfer). Remote desktop to head office (laggy, inefficient). VPN per-user (complex management, security risks). Central applications unusable from remote sites (too slow over internet). Effectively multiple separate businesses not one unified company.
With multi-site connectivity: All sites connected as single network. Shared file servers accessible from any location at LAN speeds. Centralized applications (ERP, CRM, accounting) accessed seamlessly. VoIP calls between sites free (internal extension dialing). Centralized security (single firewall policy across all sites). Simplified IT management (one network to manage not five separate ones). Business operates as cohesive unit regardless of physical location.
How it works: Router at each site creates encrypted tunnel over internet to other sites. Head office router connects to Branch A router, Branch B router, Branch C router. All inter-site traffic encrypted and routed through tunnels. Sites appear as single network (Head Office 192.168.1.x, Branch A 192.168.2.x, Branch B 192.168.3.x - all interconnected). Standard business broadband sufficient (no special connection type needed).
Cost structure: Hardware: business router with VPN capability £200-600 per site. Setup: £500-1,500 initial configuration (network engineer designs topology, configures routers, tests connectivity). Ongoing: £0 monthly (uses existing broadband, no special fees) OR £50-150/month if using managed service provider to monitor/maintain. Total 3 sites: £1,800 hardware + £1,000 setup = £2,800 upfront, then £0-450/month ongoing.
Limitations: Performance dependent on internet quality (if Branch A broadband slow, VPN slow). Single point of failure (router fails = site offline). Complex management (configure each router individually, troubleshooting requires technical expertise). Doesn't intelligently route traffic (always uses same path even if congested). Acceptable for small deployments (2-3 sites) but becomes unwieldy at scale (10+ sites = 45 VPN tunnels to manage).
Modern approach: Cloud-managed networking replacing traditional VPN. SD-WAN appliance at each site (similar cost to VPN router £300-800). Central controller (cloud-based) manages all sites from single dashboard. Automatic mesh connectivity (all sites interconnected automatically, no manual tunnel configuration). Intelligent traffic routing (chooses best path in real-time based on performance). Zero-touch deployment (ship appliance to site, plug in, auto-configures).
Key advantages: Multiple connection support (FTTP primary + 4G backup, automatic failover if primary fails). Application-aware routing (Microsoft 365 traffic via cheapest connection, ERP via fastest connection). Bandwidth aggregation (combine multiple connections for higher throughput). Centralized management (IT team manages 50 sites from single interface). Built-in security (firewall, threat prevention integrated). Performance visibility (real-time monitoring of all sites, proactive issue detection).
Cost comparison: SD-WAN appliance £400-800 per site (vs VPN router £200-600). Cloud management subscription £30-80/site/month (vs £0 for self-managed VPN). Total 5 sites: £3,000 hardware + £150-400/month subscription. Premium over traditional VPN BUT dramatically easier management, better performance, automatic failover. ROI justified for 5+ sites or businesses where connectivity critical (downtime costs exceed £500/hour).
MPLS (Multi-Protocol Label Switching): Private network provided by carrier (BT, Virgin, etc.). Dedicated connections between sites (not over public internet). Guaranteed bandwidth and latency (SLA-backed performance). Expensive: £200-500/month per site for 10-50Mbps. Installation lead time 60-90 days. Legacy technology being replaced by SD-WAN. Only justified for highly regulated industries (finance, healthcare) or businesses requiring guaranteed sub-20ms latency between sites.
Internet VPN: Uses public internet (standard business broadband). No dedicated infrastructure (traffic shares internet with everyone). Performance varies (congestion affects speed/latency). Cheap: £0 extra (just broadband cost £40-80/month per site). Instant setup (configure routers, working same day). Modern encryption (AES-256) makes security equivalent to MPLS despite public internet. Sufficient for 90% of businesses - MPLS overkill unless specific requirement.
Hybrid approach: SD-WAN supporting both MPLS + internet VPN simultaneously. Critical traffic (voice, real-time applications) via MPLS (guaranteed performance). Bulk traffic (backups, file transfers) via internet (cheaper bandwidth). Best of both worlds BUT adds complexity and cost. Alternative: dual internet connections (FTTP + 4G) with SD-WAN intelligent routing achieves similar resilience at fraction of MPLS cost.
Rethinking multi-site: Traditional model: sites connect to head office (hub-and-spoke). All traffic routes through central location (even site-to-site traffic goes via head office). Head office broadband becomes bottleneck. Modern model: sites connect directly to cloud (Microsoft 365, AWS, Salesforce). Inter-site communication via cloud orchestration. No traffic hairpinning through head office. Eliminates central bottleneck.
Example transformation: 10-person branch accessing file server at head office. Traditional: 10 users × 5Mbps each = 50Mbps upload from head office (exceeds typical 20Mbps upload capacity = slow performance). Cloud-first: migrate file server to SharePoint Online. 10 users access SharePoint directly (Microsoft's infrastructure handles load). Head office upload freed for other uses. Branch gets faster access (Microsoft CDN closer than head office). Lower cost than upgrading head office to leased line.
When site-to-site still needed: Legacy applications that can't migrate to cloud (custom ERP, manufacturing systems, specialized software). On-premise file servers too large to migrate affordably (10TB+ data = expensive cloud storage). Compliance requirements preventing cloud migration (data sovereignty, industry regulations). Real-time site-to-site collaboration (VoIP extension dialing, shared printers, local file locking). Evaluate cloud-first before investing in multi-site infrastructure.
Calculating site-to-site traffic: Head office with 50 staff + 3 branches (10 staff each). Without multi-site: each location needs bandwidth for own users only. Head office: 50 users × 5Mbps = 250Mbps. With multi-site: add branch traffic accessing head office resources. 30 branch users × 3Mbps remote access = 90Mbps additional upload at head office. Total head office upload requirement: 250Mbps (local) + 90Mbps (branches) = 340Mbps minimum. Standard FTTC insufficient - need FTTP or leased line.
Symmetric speeds critical: Multi-site traffic bidirectional (head office sends to branches, branches send to head office). Asymmetric FTTC 80/20Mbps = only 20Mbps upload (bottleneck for multi-site). Symmetric FTTP 100/100Mbps much better (100Mbps each direction). Example: file transfer head office to branch. FTTC: limited by 20Mbps upload = 2.5MB/second. FTTP 100/100: limited by 100Mbps = 12.5MB/second. 5x faster transfers justifies FTTP premium for multi-site businesses.
Branch bandwidth sizing: Small branch (5 staff): 50Mbps download + 30Mbps upload sufficient (local use + site-to-site). Medium branch (15 staff): 100Mbps symmetric recommended. Large branch (50+ staff): 300Mbps symmetric or consider leased line. Don't skimp on branch bandwidth - slow branch connection makes entire multi-site network feel slow (weakest link determines performance). Budget minimum FTTP 100/100 per site regardless of staff count.
Perimeter security vs zero trust: Traditional: strong perimeter at head office (enterprise firewall, IDS/IPS), weak security at branches (basic router firewall). Once inside network via branch, full access to everything. Modern: zero-trust model - authenticate and authorize every connection regardless of source. Branch user accessing head office server requires authentication same as external user. Prevents lateral movement if branch compromised.
Encryption requirements: All site-to-site traffic MUST be encrypted (AES-256 minimum). Public internet transmission = vulnerable to interception without encryption. VPN and SD-WAN both provide encryption (ensure enabled in configuration). MPLS traditionally unencrypted (private network assumption) but modern deployments add encryption anyway. Never run multi-site connectivity unencrypted over internet - security breach waiting to happen.
Segmentation strategy: Don't create flat network (all sites see all resources). Segment by function: Production network (manufacturing systems, isolated from office network). Guest WiFi network (customers/visitors, no access to internal resources). Management network (routers/switches/servers, admin-only access). Apply segmentation at all sites consistently. SD-WAN makes this easier (centralized policy application) vs manual configuration per site.
Phased rollout: Don't deploy all sites simultaneously. Phase 1: Pilot (head office + 1 branch, test for 2-4 weeks). Phase 2: Expand (add 2-3 more sites, validate performance). Phase 3: Complete (remaining sites, apply lessons learned). Phased approach identifies issues early at small scale vs discovering problems after full deployment (expensive to fix). Budget 3-6 months total for multi-site rollout 10+ sites.
Failover planning: Every site needs backup connectivity (primary FTTP + backup 4G minimum). SD-WAN automatically fails over if primary fails (seamless, users don't notice). Traditional VPN requires manual intervention (IT team reconfigures during outage = 1-4 hour downtime). Test failover regularly (quarterly test: disconnect primary, verify backup works). Untested backup = false sense of security.
Documentation requirements: Network topology diagram (all sites, connections, IP addressing). Configuration backup (router configs stored securely, version controlled). Contact list (provider support numbers, escalation contacts, on-call IT staff). Runbook (step-by-step recovery procedures for common issues). Without documentation: staff turnover = knowledge loss = can't troubleshoot issues. Invest 10 hours documenting properly saves 100 hours troubleshooting later.
We'll design the right topology for your locations, recommend VPN vs SD-WAN, and ensure reliable site-to-site connectivity.
Get Help →Notice periods (30-90 days), early termination fees (£300-600), switching timeline (10-30 days), overlap costs, and seamless migration process.
Contract end approaching: Best time to switch = 60-90 days before contract expiry. Gives time to compare providers, negotiate deals, schedule installation without rushing. Out-of-contract pricing brutal (30-50% premium). Example: £50/month in-contract becomes £65-75/month out-of-contract. Staying beyond contract end costs £180-300 extra annually. Set calendar reminder 120 days before expiry to start shopping.
Poor performance: Persistent speed issues (consistently 40-50% below advertised), frequent outages (more than 3-4 times yearly), poor customer service (hours on hold, unresolved complaints). Document issues: speed test results over 2 weeks, fault reference numbers, call recordings. Use as leverage with current provider (threaten to switch unless improved). If no improvement, justified switching mid-contract despite early termination fees.
Better technology available: FTTP newly available at your address (upgrade from FTTC 80/20 to FTTP 300/300). New provider offers symmetric speeds your current provider can't match. 5G coverage improved enabling wireless backup option. Technology upgrade often worth early termination fee: £300 exit fee ÷ 24 months remaining = £12.50/month effective cost. If new service £15/month cheaper or significantly faster, ROI positive.
Calculation methods: Method 1: Remaining months × monthly cost. 12 months left on £50/month contract = £600 early exit. Method 2: Capped fee regardless of remaining time (e.g. maximum £300 even if £600 calculated). Method 3: Sliding scale (100% first year, 70% second year, 40% third year). Check your specific contract terms - varies by provider. Get written quote of exact exit fee before committing to switch.
When fees waived: Provider breach (persistent service failure, SLA violations). Moving premises outside provider's coverage area (must prove with new address confirmation). Provider increases prices beyond contract terms (some contracts allow exit if price rise exceeds inflation + 3.9%). Negotiate: "I'm switching to [competitor] - will you waive exit fee to keep my business?" Sometimes works (losing £1,200 over 24 months hurts more than waiving £300 exit fee).
New provider contributions: Some providers offer "switch incentives" - contribute £100-300 toward early termination fees if you switch to them. Usually requires 24-36 month contract (recouping their contribution over time). Calculate total cost: New provider £45/month × 24 months = £1,080, minus £200 switching contribution = £880 net. Current provider £50/month × 12 months remaining = £600 exit fee + £50/month × 12 months = £1,200 total. Switching saves £320 despite exit fee.
Cease & re-provide method (traditional): Give current provider notice (30-90 days depending on contract). Schedule cancellation date. New provider installs on same day as cancellation. Requires coordination (if cancellation 15th March, new install must be 15th March or you have downtime). High risk approach - timing slips = offline. Avoid unless necessary (moving premises, changing phone number).
Simultaneous provide (recommended): New provider installs while current service active. Run both connections simultaneously for 1-2 weeks (overlap period). Test new connection thoroughly before cancelling old. Give notice to old provider only after confirming new connection working perfectly. Costs extra (paying both for overlap) but eliminates downtime risk. Overlap cost: £50 old + £50 new × 2 weeks = £50 extra. Worth it for business continuity.
Timeline breakdown: Day 1: Order new service. Day 7-10: New provider surveys (if FTTP). Day 15-20: New installation completed, test thoroughly. Day 21: Give 30-day notice to old provider. Day 51: Old service cancelled, new service primary. Total process: 50-60 days from decision to completion. Don't rush - proper testing during overlap prevents discovering issues after old connection cancelled.
Geographic numbers (landlines): Fully portable - can keep number when switching providers. Process: request number port from new provider (not old provider - common mistake). New provider contacts old provider with port request. Port completes on switchover day (number moves to new service). Important: don't cancel old service before port completes or number lost permanently. Port timeline: 10-15 working days from request to completion.
VoIP numbers (cloud-based): Different process than landlines. May or may not be portable depending on how obtained. VoIP provider owns number (you lease it) = can't port to different VoIP provider usually. Workaround: keep minimal VoIP service with old provider (£5-10/month) just for number, forward to new number. Alternative: accept new number, update all stationery/website/directories. Budget 3-6 months transition period for customers adapting to new number.
Number porting failures: Incorrect account details provided (name/address doesn't match old provider records exactly). Old account has outstanding balance (pay before porting). Old provider delays/blocks port (anti-competitive but happens - escalate to regulator). Port fails on switchover day (emergency: activate call forwarding from old to new number as temporary fix, resolve port issue). Always have backup plan for number porting - don't assume it'll work perfectly.
Router ownership: Rented router (£5-10/month) must return to old provider within 14 days of cancellation or charged full value (£100-200). Own router = keep it, potentially use with new provider (if compatible). New provider supplies new router (£0-100 depending on package). Plan: keep old router connected until new router fully configured and tested. Return old router promptly to avoid charges (tracked delivery, photograph serial number as proof).
Static IP migration: Static IP from old provider = can't take to new provider (IP addresses provider-owned). New provider assigns different static IP. Impact: update DNS records (A records, MX records pointing to old IP must change to new IP). Update firewall rules (allow new IP through corporate firewalls). Update static IP references in applications. Timeline: DNS changes take 4-48 hours to propagate. Schedule migration over weekend to minimize business impact.
Network reconfiguration: Internal network likely configured for old router (DHCP range, DNS servers, port forwarding rules). Document current configuration before switching (screenshot all router settings). Replicate configuration on new router (same internal IP ranges prevents need to reconfigure all devices). Test methodically: internet connectivity, internal network access, VPN, VoIP, printers. Expect 2-4 hours reconfiguration work even with good planning. Budget £200-500 IT support if no in-house expertise.
Not checking availability first: Order new FTTP service, discover your address not actually covered (sales rep wrong, system error, building restrictions). Now locked into contract you can't fulfill. Always verify: independent postcode checker (Openreach website), request site survey before committing, get written confirmation of availability. Don't sign contract based on verbal availability claims.
Forgetting email/domain dependencies: Business email hosted by broadband provider (common with older setups). Cancelling broadband = losing email access = disaster. Migrate email to independent provider (Microsoft 365, Google Workspace) BEFORE switching broadband. Check: domain registration (is domain registered via broadband provider? Transfer to independent registrar first). Web hosting (website hosted by broadband provider? Migrate to separate hosting first). Never tie business-critical services to broadband provider.
Inadequate testing period: New connection installed Friday, cancel old connection Monday. Discover issue Tuesday (too late, old connection gone). Always allow 1-2 week overlap for thorough testing. Test checklist: speed tests (peak hours), all staff devices connecting, VoIP quality, VPN connectivity, file server access, printer connectivity, video conferencing. Find problems during overlap = switch back temporarily, resolve issues, then complete switch. Rush migration = expensive problems.
When to negotiate: 90 days before contract end, call current provider: "I'm considering switching to [competitor] offering £40/month for 300Mbps. What can you offer to keep me?" Retention team (different from sales) has authority to discount. Typical offers: 20-30% discount, free speed upgrade, waived fees. Don't accept first offer - "Competitor also includes free static IP, can you match?" Push for best possible terms.
Comparing total value: Retention offer: Stay for £45/month (down from £60), 12-month contract, free router upgrade (£150 value). Competitor offer: £40/month, 24-month contract, £100 installation fee, £50/month router rental avoided. Calculate: Retention = £540/year. Competitor = £480/year + £100 install - £50 saved = £530 first year, then £480 ongoing. Competitor better financially BUT consider: service quality reputation, hassle of switching, tested reliability vs unknown. Sometimes worth £60/year to avoid switching headaches.
When retention deals insufficient: Provider can't match competitor technology (you want FTTP, they only offer FTTC). Repeated service failures (no amount of discount compensates for unreliability). Better SLA available elsewhere (enhanced support worth more than price discount). Don't stay for small saving if fundamentally better service available. £10/month saving (£120/year) not worth it if competitor offers superior uptime, speed, and support.
We'll manage the entire process - calculate exit fees, coordinate installation timing, handle number porting, and ensure zero downtime.
Get Help →PSTN shutdown by 2027, ISDN phase-out, impacts on landlines/fax/alarms, migration to VoIP/FTTP, and transition planning timeline.
PSTN (Public Switched Telephone Network) shutdown: Traditional copper phone network being decommissioned by January 2027. Analog phone lines (landlines) cease working. ISDN lines (business phone systems) discontinued. Forced migration to digital alternatives (VoIP over broadband, mobile). Affects: landline phones, fax machines, alarm systems, PDQ machines using phone lines, legacy systems relying on copper connectivity.
Why it's happening: Copper infrastructure ageing (installed 1960s-1980s, expensive to maintain). Declining usage (90% reduction in landline calls since 2000 peak). Digital alternatives superior (better quality, lower cost, more features). BT Openreach saving £1 billion+ annually by decommissioning copper network. Investment redirected to FTTP rollout. Inevitable technological transition - like analog TV to digital switchover.
Timeline: 2023-2025: New PSTN/ISDN orders stopped (can't get new copper lines). January 2027: Complete PSTN shutdown (all copper lines cease functioning). Regional rollout: some areas migrated earlier (2025-2026) as pilots. Check your area: Openreach provides switchoff dates by postcode. Don't wait until 2026 - plan migration now (avoid last-minute rush when engineers/equipment scarce).
Analog landlines: Traditional desk phones plugged into wall socket (BT master socket). Post-2027: completely non-functional (no dial tone, can't make/receive calls). Must replace with: VoIP desk phones (digital phones using broadband connection), softphones (computer/mobile app for calls), cloud phone system. Cost: £50-150 per desk phone replacement + £20-50/user/month cloud phone system. Budget accordingly for fleet replacement.
ISDN systems (PBX): Business phone systems with multiple extensions, call routing, voicemail. ISDN30 (large offices, 30+ lines) and ISDN2 (small offices, 2 lines) both discontinued. Legacy PBX hardware worthless post-2027. Options: Replace with cloud PBX (Teams Phone, RingCentral, 3CX - £15-30/user/month). Hybrid approach (keep PBX, add SIP trunks for connectivity). Full replacement (rip out old system, install new). Most businesses choosing cloud PBX (lower upfront cost, scalability, remote working support).
Fax machines: Still common in legal, medical, construction sectors. Traditional fax over phone line = stops working 2027. Alternatives: VoIP fax adapter (£100-200 device converting analog fax to digital), cloud fax service (eFax, RingCentral Fax - £10-20/month), eliminate fax entirely (DocuSign, email with encryption). Reliability warning: VoIP fax problematic (jitter/latency causes transmission failures). Consider cloud fax service or phasing out fax completely.
Alarm systems: Fire alarms, security alarms, lift emergency phones often use analog phone lines for monitoring/alerts. Post-2027: monitoring fails (alarms trigger but monitoring company not notified). Compliance risk: fire safety regulations require monitored alarms. Solutions: Cellular alarm communicators (4G/5G connectivity instead of phone line - £150-300), IP alarm panels (broadband connection - £200-400), hybrid (keep analog alarm, add cellular backup). Audit all alarm systems now - identify dependencies on copper lines.
Payment terminals (PDQ machines): Older card machines using phone line dial-up. Slow (30-60 seconds per transaction) but reliable. Post-2027: completely non-functional. Replacement: IP-connected card machines (broadband/WiFi connectivity - faster, modern features). 4G card machines (mobile network connectivity - good for mobile businesses). Cost: £0-50/month depending on payment processor deal. Opportunity: upgrade brings contactless, faster processing, better reporting. Turn forced migration into business improvement.
Telecare & medical alarms: Elderly care pendants, medical alert systems. Often rely on landline to call monitoring centre. Post-2027: life-threatening if system fails during emergency. Government mandates suppliers provide migration path but responsibility on user to upgrade. For business: office first aid systems, lone worker alarms check connectivity method. For personal: elderly relatives/staff using telecare must upgrade before 2027. Don't assume supplier will automatically upgrade - verify explicitly.
Broadband dependency: VoIP requires reliable broadband (analog landlines work during power cuts - VoIP doesn't). Power outage = no broadband = no phones. Mitigation: UPS battery backup (£100-300) powers router/phones during outage (2-4 hours runtime). 4G backup connection (automatic failover if broadband fails). For critical businesses: consider hybrid (VoIP primary + mobile phones backup). Don't migrate blindly - plan for broadband dependency.
Bandwidth requirements: 10 staff × 2 concurrent calls average = 20 calls × 100kbps = 2Mbps bandwidth needed. Plus normal internet use (cloud apps, email, browsing) = 5-10Mbps per staff. Total: 50-100Mbps recommended for 10-staff office migrating to VoIP. Current FTTC 40/10Mbps may be insufficient (especially upload - VoIP needs upload bandwidth). Consider broadband upgrade concurrent with VoIP migration. Don't just replace phones - ensure infrastructure supports it.
Quality of Service (QoS): VoIP traffic must be prioritized over other internet use. Without QoS: large file download consumes all bandwidth = choppy calls. Configure router to reserve bandwidth for VoIP (highest priority), general browsing (low priority). Requires business-grade router (£150-400). Consumer routers often lack proper QoS. Budget router upgrade as part of VoIP migration - essential for call quality.
12-18 months before switchoff (NOW): Audit current systems (list all devices using phone lines: phones, fax, alarms, PDQ, door entry, lift phones). Assess broadband adequacy (speed test, calculate VoIP bandwidth needs). Research VoIP providers (get 3 quotes, compare features/pricing). Budget for migration (phones, system, installation, training). Don't rush decisions - thorough planning prevents expensive mistakes.
6-12 months before: Select VoIP provider, place order (lead times increasing as 2027 approaches - equipment/engineer shortages). Upgrade broadband if needed (move to FTTP, increase speed tier). Install UPS backup power. Test pilot (install VoIP for 2-3 users, validate quality before full rollout). Identify issues early while time to resolve. Phased approach reduces risk vs big-bang migration.
3-6 months before: Full VoIP deployment (all users migrated). Port phone numbers (keep existing business numbers - 10-15 days process). Train staff (new phone features, softphone apps, troubleshooting). Run parallel (keep old PSTN lines active 30-60 days alongside VoIP as safety net). Test thoroughly (call quality, voicemail, call routing, emergency services). Cancel PSTN only after VoIP proven reliable. Better to pay overlap costs than discover issues after old system gone.
One-time migration costs: 10-person office example. VoIP desk phones: 10 × £80 = £800. Business router with QoS: £250. UPS backup power: £150. Installation/configuration: £500. Broadband upgrade (FTTC to FTTP): £200 install. Total upfront: £1,900. Painful BUT mandatory (no choice - copper lines stopping). Spread cost: many VoIP providers offer phone rental (£5-10/month per handset) reducing upfront cost (rent vs buy decision).
Ongoing cost comparison: Current ISDN2: £45/month line rental + £0.05/minute calls = £45-80/month typical. VoIP replacement: £20/user/month cloud phone system × 10 users = £200/month. Looks more expensive BUT includes unlimited UK calls (vs per-minute ISDN charges). Plus: no call charges, international calls cheaper (£0.01-0.05/min vs £0.15-0.40/min ISDN), mobile apps included (staff can take calls on mobiles using business number). TCO often similar or cheaper despite higher base price.
Hidden savings: Reduced wiring costs (new office fit-out: VoIP uses existing network cables vs dedicated phone cabling - £500-1,500 saving per office). Easier moves/adds/changes (add new user in 5 minutes via web portal vs engineer callout £100+). Remote working support (staff work from home using business phone system - no forwarding charges). Unified communications (integrate phone with email, Teams, CRM - productivity gains). Forced migration creating opportunities for business improvement beyond just replacing phones.
Bundled vs separate: Broadband provider offering VoIP (BT, TalkTalk, Virgin) = convenient, single bill, integrated support. Independent VoIP provider (RingCentral, 8x8, Vonage) = more features, better reliability, specialized support. Consider: bundled works for simple needs (10 users, basic calling). Specialist provider better for complex requirements (call centre, integration with CRM, advanced routing). Get quotes from both before deciding.
Key features to check: Number porting (can you keep existing business numbers?). Emergency services access (999/112 working correctly with address location). Call recording (legal requirements in some industries). Mobile apps (iOS/Android for remote working). Integration (Teams, Salesforce, Xero connectivity). Auto-attendant (professional greeting, routing menu). Voicemail-to-email (voicemails sent as audio files). Make list of must-have features before shopping - not all providers offer everything.
Trial periods: Request 30-day trial or money-back guarantee. Test: call quality (make test calls, check clarity). Mobile apps (test remote working capability). Support responsiveness (call support, check hold times/knowledge). Integration (test CRM/Teams connectivity if relevant). Don't commit to 36-month contract without thorough testing. Switching VoIP providers difficult once established (number porting, retraining staff) - choose carefully first time.
We'll audit your current systems, recommend VoIP solutions, coordinate broadband upgrades, and manage the entire migration before the 2027 deadline.
Get Help →Price differences (£15-25/month premium), SLA guarantees, contention ratios (20:1 vs 50:1), support quality, and terms of service restrictions.
Residential broadband: Designed for home use (streaming, browsing, gaming). Priced aggressively (£20-35/month for 50-100Mbps). Evening/weekend peak performance (when households online). Minimal support (automated chatbots, long hold times). No SLA guarantees (best-effort service). 50:1 contention ratio (shared with 49 other homes). Terms prohibit business use technically (rarely enforced but grounds for termination).
Business broadband: Designed for commercial use (daytime reliability, consistent performance). Premium pricing (£35-65/month for similar speeds). Daytime peak optimization (9am-5pm when businesses need it). Dedicated support (phone support, faster response, technical expertise). SLA guarantees (99-99.9% uptime, fix-time commitments). 20:1 contention ratio (better daytime performance). Terms explicitly allow business use (invoices for tax purposes, VAT registration).
Real-world impact: Small business (5 staff) on residential broadband saves £15/month = £180/year. Risk: service terminated for T&C breach, daytime performance poor (50:1 contention), outages unfixed for days (no SLA), support unhelpful for business needs. One 8-hour outage costing £400 in lost productivity exceeds annual saving 2x. False economy for most businesses - business broadband worth premium.
Like-for-like pricing: Residential 67Mbps FTTC = £28/month. Business 80Mbps FTTC = £45/month. Difference: £17/month = £204/year premium. What you get: Better contention ratio (faster daytime speeds), SLA guarantee (99.5% uptime minimum), business support (phone support 9am-6pm), static IP often included, invoicing/VAT for accounting. ROI: If prevents one 4-hour outage yearly (worth £200+ productivity), premium justified.
Hidden residential costs: Advertised £28/month becomes £35/month after promotional period (12-18 months). Price rises mid-contract (RPI + 3.9% annually = compound increases). Out-of-contract penalty (£28 → £38-45/month if forget to renegotiate). Static IP extra (£8-10/month if needed). Total: £35-55/month after year 1. Business broadband pricing more transparent (fixed prices, clear terms, professional invoicing).
When residential acceptable: Solo trader working from home (1 person = low impact if outage), very small business (2-3 people, can work elsewhere during outage), startup on tight budget (prioritizing cash flow short-term), temporary arrangement (planning upgrade within 12 months). Not acceptable: 5+ staff dependent on connectivity, customer-facing operations (calls, e-commerce), VoIP phone system, cloud-based business applications. Size of business matters.
Residential support experience: Fault reported Friday 6pm. Automated chatbot (can't resolve). Phone support (45-minute hold, offshore call centre, reading scripts). Engineer scheduled Tuesday (4 working days away). Fault fixed Wednesday. Total downtime: 5 days. No compensation (no SLA). Impact: business offline full working week. Lost revenue: 5 days × £500/day = £2,500. Saved £17/month = not worth it.
Business support experience: Fault reported Friday 6pm. Direct phone line (5-minute hold, UK-based technical team). Remote diagnostics attempted immediately. Engineer scheduled next working day (Monday 9am) if needed. SLA: 24-hour fix time guaranteed. Fault fixed Monday 2pm. Total downtime: 68 hours (mostly weekend). Compensation: SLA breach = credit applied. Impact: minimal business disruption (weekend), swift resolution, financial recourse for breach.
Proactive vs reactive: Business providers monitor circuits (identify issues before customer notices, often fix remotely before impacting service). Residential providers reactive only (wait for customer complaints, minimal proactive monitoring). Example: business provider detects degrading signal Friday night, dispatches engineer Saturday morning preventatively. Residential provider waits until Monday customer complaint, schedules engineer Wednesday. Different service philosophy reflected in pricing.
Peak time performance: Residential 67Mbps (50:1 contention). Speed test 3am = 65Mbps (excellent, nobody online). Speed test 2pm Wednesday = 28Mbps (57% reduction, many working from home). Business 80Mbps (20:1 contention). Speed test 3am = 78Mbps. Speed test 2pm Wednesday = 68Mbps (13% reduction, much more stable). Same headline speed but vastly different daytime experience when businesses need it.
Upload speed consistency: Critical for business (video calls, cloud backups, VoIP). Residential FTTC 67/18Mbps. Upload 3am = 17Mbps. Upload 11am = 7Mbps (61% reduction - unusable for multiple video calls). Business FTTC 80/20Mbps. Upload 3am = 19Mbps. Upload 11am = 16Mbps (16% reduction - still functional). Consistent upload performance worth premium for cloud-heavy businesses.
Testing before committing: If considering residential for business use, test during business hours over 2-week period. Run speed tests every hour 9am-5pm. Document results. If speeds consistently 50%+ below advertised during working hours, residential unsuitable. If speeds remain 80%+ of advertised, might be acceptable for low-demand business. Don't assume evening/weekend test results reflect daytime performance.
Residential T&Cs prohibition: Most residential broadband contracts explicitly prohibit commercial use. Clause typically: "Service for domestic and private non-commercial use only. Commercial use prohibited and grounds for immediate termination without refund." Enforcement rare (providers don't actively monitor) BUT legal ground for cancellation. If provider suspects business use (high daytime usage, static IP request, multiple devices), can investigate and terminate.
Tax and accounting implications: Residential broadband = personal expense (not business expense for tax purposes without proving portion used for business). Business broadband = legitimate business expense (100% tax deductible, proper VAT invoicing). For £45/month business broadband as 20% taxpayer, net cost £36/month (£9 tax relief). Residential £28/month no tax relief = net £28. Effective difference £8/month not £17/month when accounting for tax treatment.
Insurance and liability: Business insurance policies may require business-grade services for coverage. Using residential broadband for business = potential insurance claim rejection if connectivity failure causes loss. Example: e-commerce site offline due to residential broadband failure, losing £5,000 sales. Business interruption insurance may not pay out (T&Cs breach - using non-business-grade infrastructure). Check insurance policy requirements before choosing residential.
Residential asymmetric: Download-optimized (streaming, downloading). Typical: 67Mbps download / 18Mbps upload. Ratio 3.7:1. Works for consumer use (downloading content) but problematic for business (uploading to cloud, video conferencing, VoIP). 10-person office on 18Mbps upload = 1.8Mbps per person (too slow for video calls + cloud apps simultaneously).
Business symmetric options: FTTP business packages often symmetric (100/100Mbps, 300/300Mbps). Upload matches download (essential for modern cloud workflows). Premium £10-20/month over residential equivalent BUT eliminates upload bottleneck. ROI: If upload bottleneck costs 30 minutes daily staff productivity (waiting for cloud saves, choppy video calls), £20/month justified for 5+ person team. Upload performance critical for business - don't focus only on download speed.
Calculating upload needs: List upload activities: Cloud backups (how much data nightly?), video calls (how many concurrent?), VoIP (how many lines?), file uploads (how frequent?). Calculate total upload bandwidth needed. If exceeds 50% of residential package upload speed, asymmetric insufficient. Example: Need 15Mbps upload, residential offers 18Mbps = operating at 83% capacity (no headroom for spikes). Business 100/100Mbps or symmetric FTTP essential.
Choose residential if: Solo trader/1-2 people, working from home occasionally (not primary workspace), low connectivity dependency (can work offline or elsewhere during outages), very tight budget (every £20/month matters), backup plans in place (mobile hotspot, nearby coworking space). Understand risks and have mitigation strategies. Don't choose residential by default to save money without considering consequences.
Choose business if: 5+ employees, dedicated office premises, cloud-dependent operations (Office 365, cloud ERP, cloud backup), VoIP phone system, customer-facing connectivity (e-commerce, call centre), professional reputation matters (can't tell customers "our internet is down"), downtime costs significant (more than £200/day lost productivity). Business broadband insurance against expensive disruptions.
Hybrid approach: Some businesses use residential primary + business backup (or vice versa). Example: Residential FTTP 300Mbps (£35/month) for general use + business 4G (£30/month) for VoIP/critical apps with automatic failover. Total £65/month = similar cost to business FTTP alone but better resilience. SD-WAN manages traffic routing. Creative solution balancing cost and reliability. Consider all options before committing.
We'll assess your business needs and recommend whether business broadband worth the premium or residential sufficient for your use case.
Get Advice →4G/5G backup (£30-50/month), dual-WAN configurations, automatic failover, mobile hotspots, and business continuity planning.
Single point of failure risk: Business with one broadband connection = complete dependency. Fibre cable cut by roadworks = entire office offline. Router failure = no connectivity until replacement arrives. Even 99.9% SLA allows 8.76 hours downtime yearly. For businesses where 4-hour outage costs £1,000+ in lost revenue, backup connectivity essential insurance. Don't wait for outage to discover you needed backup.
Downtime cost calculation: 10-person office, average £20/hour staff cost = £200/hour payroll. During 4-hour broadband outage: £800 payroll spent with zero productivity. Add lost revenue (e-commerce offline, calls missed, deliveries delayed) = easily £1,000-2,000 total impact. Backup 4G connection costs £30-50/month = £360-600/year. Single prevented outage pays for entire year of backup. ROI obvious for connectivity-dependent businesses.
Types of businesses needing backup: E-commerce (every hour down = direct revenue loss). Call centres (can't handle calls = customers to competitors). Professional services with deadlines (solicitors, accountants missing filing deadlines = regulatory penalties). Medical facilities (appointment systems, prescription systems offline = patient safety). Any business where connectivity outage causes immediate £500+ impact. If outage costs less than £500, backup may not justify expense.
Dedicated 4G/5G router: Separate business-grade mobile router (£150-400 hardware). Dedicated data SIM (unlimited or high-cap plan £30-50/month). Sits alongside primary router on separate network. Only activates when primary fails (manual or automatic switchover). Advantage: Always ready, independent of primary connection. Disadvantage: Monthly cost regardless of whether used. Best for: businesses where guaranteed backup essential (monthly cost justified by risk mitigation).
Bonded/hybrid connections: SD-WAN or bonding device combining primary FTTP + 4G simultaneously. Normal operation: all traffic via FTTP (fastest). Primary fails: instant automatic switchover to 4G (usually under 1 second - users don't notice). Primary restored: automatic failback. Seamless user experience. Cost: £50-150/month for bonding service + 4G data. More expensive but zero manual intervention needed. Ideal for: businesses requiring true zero-downtime connectivity.
Pay-as-you-go mobile hotspot: Keep mobile phone or MiFi device with PAYG SIM (£0 monthly cost when unused). During outage: activate hotspot, connect critical devices, top-up data as needed (£10-20 for temporary use). Advantage: £0 ongoing cost, simple solution. Disadvantage: Manual activation (staff realizing outage, configuring hotspot = 10-30 minute delay), limited performance (5-10 devices max, slower speeds), requires staff training. Best for: small businesses with occasional short outages (2-3 times yearly).
Active/passive failover: Primary connection (FTTP) active, backup connection (4G) passive. Router monitors primary constantly (ICMP pings every 10 seconds). Primary fails (3 consecutive ping failures = 30 seconds detection) → router switches all traffic to backup. Primary restored → automatic failback after stability confirmed (5 minutes consecutive uptime). Downtime during failure: 30-60 seconds (acceptable for most businesses, critical apps may timeout).
Active/active load balancing: Both connections active simultaneously. Traffic distributed across both (50/50 split or weighted by speed). Advantage: utilizing backup connection's bandwidth even when primary working (effectively faster combined speed). Disadvantage: some applications problematic with changing IP addresses (VPN, banking, some cloud apps). More complex configuration. Best for: high-bandwidth businesses wanting maximum throughput, not just failover protection.
Router requirements: Business-grade dual-WAN router essential (£150-600 depending on features). Consumer routers lack proper failover capability. Key features needed: automatic failover detection, failback capability, WAN health monitoring, per-application routing rules (critical apps via primary, bulk downloads via backup). Don't cheap out on router - poor quality failover unreliable (defeats purpose of backup). Recommend: Draytek, Cisco, Ubiquiti, or similar business-grade brands.
4G backup: Coverage: 90-95% UK premises. Speed: 20-80Mbps typical. Latency: 30-50ms (acceptable for most business apps). Cost: £25-40/month unlimited data. Best for: urban/suburban locations with good 4G signal. Test signal strength at exact office location before committing (mobile networks vary dramatically street-to-street). Adequate for: VoIP, cloud apps, email, browsing during outage. Won't match FTTP speed but keeps business operational.
5G backup: Coverage: 40-50% UK (mainly cities). Speed: 100-300Mbps possible. Latency: 20-40ms (better than 4G). Cost: £35-60/month unlimited. Best for: locations with confirmed 5G coverage, businesses needing higher backup speeds (large file transfers continue during outage). Warning: 5G coverage patchy - indoor penetration worse than 4G (thick walls block signal). External antenna often needed (£100-300 additional). Future-proof choice but verify coverage thoroughly first.
Second fixed-line (FTTC/FTTP): Ultimate redundancy: two separate physical connections from different providers. Primary: FTTP Provider A. Backup: FTTP Provider B or FTTC Provider C. True diversity (different infrastructure = unlikely both fail simultaneously). Cost: £45 primary + £40 backup = £85/month total. Expensive but enterprise-grade reliability. Best for: mission-critical businesses (data centres, call centres, financial services), businesses where even 1-hour downtime costs £2,000+. Overkill for most SMEs.
Automatic failover advantages: Instant switchover (30-60 seconds typical). No manual intervention needed (works outside business hours, when IT staff unavailable). Users unaware outage occurred (seamless experience). Critical for: businesses operating evenings/weekends, businesses without technical staff onsite, high-uptime requirements (can't tolerate 30-minute manual switchover delay). Additional cost: dual-WAN router (£150-600) + configuration (£200-500 setup).
Manual failover process: Primary fails → staff notice (5-30 minutes depending on what they're doing) → call IT support → IT remotely reconfigures or talks staff through switching cables → backup operational (total 30-60 minutes from failure to restoration). Acceptable for: small businesses with IT support available, businesses where 1-hour downtime tolerable, budget-conscious businesses saving dual-WAN router cost. Requires: clear documentation (step-by-step failover procedure), staff training (who does what), backup connectivity pre-configured and tested.
Hybrid approach: Automatic failover for critical systems (VoIP phones, POS terminals, servers), manual failover for general office (staff PCs, WiFi). Protects revenue-generating systems immediately while avoiding expensive network-wide automatic failover infrastructure. Example: VoIP phones connected to dual-WAN router with auto-failover (£400 investment protecting £50,000/year phone revenue). Office PCs on single connection with manual failover instructions (acceptable for email/browsing). Targeted protection maximizes ROI.
Regular testing schedule: Monthly: disconnect primary connection, verify backup activates correctly, test critical applications on backup (VoIP calls, cloud apps, payment processing), document results. Quarterly: full business operations test on backup for 2-4 hours (simulate extended outage), measure performance vs primary, identify applications that don't work on backup. Annual: review backup adequacy (has business grown? Need higher capacity backup?), review costs vs alternatives, verify failover automation still working correctly.
Common testing discoveries: Backup 4G speeds insufficient for video conferencing (works for VoIP but not Teams meetings = adjust expectations or upgrade to 5G backup). Automatic failover not triggering (configuration error discovered during test = fix before real outage). Cloud apps requiring static IP don't work on backup (dynamic 4G IP = apps fail = need static IP 4G or different backup solution). Testing reveals issues in controlled environment vs discovering during actual emergency outage.
Data allowance monitoring: If using capped backup plan (e.g., 100GB/month), monitor monthly usage even when not failed over. Some backup connections used for testing, software updates, background traffic can consume allowance. Exceeding cap during actual outage = expensive overage charges or speed throttling (defeats purpose). Recommendation: unlimited data plans for backup connectivity (£10-15/month premium over capped plans, eliminates surprise costs during extended outage).
Simple backup (mobile hotspot): Cost: £0 monthly (PAYG SIM kept for emergencies). One-time: £30 MiFi device. Annual cost: £0 (plus £10-20 data during actual outage). Suitable for: 1-5 person businesses, very occasional outages (1-2 times yearly lasting under 4 hours), downtime cost under £200. Limitation: manual activation delay, limited device support, staff training needed. Break-even: If saves one £200 productivity loss yearly, justified.
Automatic 4G backup: Cost: £300 router + £40/month 4G unlimited = £300 + £480/year = £780 first year, £480 ongoing. Suitable for: 10-20 person businesses, downtime cost £500-1,000/hour, outages 2-4 times yearly. Limitation: still slower than primary (video conferencing may struggle). Break-even: Prevents one 4-hour outage worth £2,000 annually = 2.5x ROI first year, 4x ROI ongoing years.
Dual FTTP connections: Cost: £50 primary + £50 backup + £400 dual-WAN router = £1,600 first year, £1,200 ongoing. Suitable for: mission-critical businesses (call centres, e-commerce, financial services), downtime cost £2,000+/hour, zero-downtime requirement. Limitation: expensive for small businesses. Break-even: Prevents single 8-hour outage worth £16,000 annually = 10x ROI. Only justified for businesses where downtime genuinely catastrophic.
We'll calculate your downtime costs, recommend appropriate backup solution (4G/5G/dual-WAN), and configure automatic failover.
Get Help →Cloud PBX (£15-30/user/month), desk phone setup, mobile apps, auto-attendant, call routing, voicemail-to-email, and Teams integration.
Cloud PBX (hosted): Phone system runs in provider's data centre, accessed via internet. Monthly subscription per user (£15-30/month typical). No hardware to buy (just desk phones/headsets). Instant scalability (add users in minutes via web portal). Automatic updates (new features deployed by provider). Disaster recovery built-in (calls route to mobiles if office offline). Best for: most modern businesses, especially those with remote workers or multiple locations.
On-premise PBX: Phone system hardware installed at your office. Large upfront cost (£3,000-10,000 for 10-50 users). You manage and maintain (IT expertise needed). Difficult to scale (adding capacity requires hardware upgrades). Your responsibility for backups and redundancy. Best for: very large businesses (100+ users where per-user cloud cost exceeds on-premise TCO), specific regulatory requirements preventing cloud, locations with unreliable internet. For most SMEs, cloud PBX superior option.
Hybrid solutions: On-premise PBX with cloud connectivity (SIP trunks). Keeps existing hardware investment while gaining cloud benefits (remote workers, DR, lower call costs). Transition strategy: use hybrid while planning full cloud migration. Cost: existing hardware + £10-20/user/month cloud services. Acceptable for businesses with recent PBX investment (under 3 years old) wanting cloud features without replacing entire system immediately.
VoIP desk phones: Physical phones on desks (look/feel like traditional phones). Cost: £80-200 per handset (buy) or £5-10/month (rent). Advantages: Familiar for staff, better audio quality than PC speakers, work during PC crashes, professional appearance for reception/customer-facing roles. Disadvantages: Physical hardware to manage, tied to desk location, can't take calls when away from desk. Best for: receptionists, sales teams making heavy calls, staff preferring traditional phones, professional office environments.
Softphones (PC/mobile apps): Software application on computer or smartphone. Cost: usually included in cloud PBX subscription (£0 extra). Advantages: Ultimate flexibility (take calls anywhere on any device), no hardware costs, easy remote working, click-to-dial from CRM/email. Disadvantages: Audio quality dependent on PC speakers/headset, distractions from other PC apps, battery drain on mobiles. Best for: remote workers, mobile staff, modern tech-comfortable teams, businesses minimizing hardware costs.
Hybrid approach (recommended): Desk phones for heavy phone users (reception, sales, support), softphones for everyone else (management, back-office, field workers). Optimize costs while maintaining professional phone capabilities where needed. Example 20-person business: 5 desk phones (£400 buy or £25/month rent) + 15 softphone-only users (£0 extra hardware). Balances professionalism, flexibility, and cost control.
Auto-attendant (IVR): Automated greeting menu ("Press 1 for Sales, 2 for Support"). Eliminates receptionist answering every call (reduces staffing or frees receptionist for other tasks). Professional image for small businesses (sounds like large company). Cost: usually included in business VoIP plans. Setup: record professional greeting (£50-100 voice artist or DIY), configure routing rules (which extensions for which menu options), test thoroughly before going live. Essential for: businesses with multiple departments, businesses wanting professional image, high call volumes.
Call routing & queuing: Intelligent call distribution (calls routed based on time, caller ID, agent availability). Queue management (hold music, estimated wait time, callback option). Overflow routing (calls to mobiles if all desk phones busy). Example: Sales calls route to sales team round-robin, support calls route based on customer tier (priority customers to senior team), after-hours calls to voicemail or mobile. Improves customer experience and operational efficiency. Usually included in mid-tier business plans (£20-25/user/month).
Voicemail-to-email: Voicemails sent as audio files to email inbox. Listen to voicemails anywhere (don't need to dial into mailbox). Visual indication of new messages (email notification). Archive/search voicemails (email search tools). Essential for: remote workers, mobile staff, anyone who doesn't want to check voicemail separately. Usually standard feature. Some systems offer transcription (voicemail converted to text £5-10/user/month extra) - accuracy 70-80%, useful for quickly scanning messages.
Microsoft Teams integration: VoIP provider integrates with Teams (calls via Teams interface using business phone number). Benefits: Single app for chat + calls + meetings, familiar interface for Teams users, call history/recordings in Teams. Cost: £5-15/user/month addon to Teams license. Popular providers: RingCentral, Zoom Phone, 3CX (all offer Teams integration). Best for: businesses already using Teams heavily, wanting unified communications without separate phone app.
CRM integration (Salesforce, HubSpot, Zoho): Click-to-dial from CRM (click customer phone number, VoIP automatically dials). Pop-up caller information (incoming call displays customer record). Call logging (all calls automatically logged in CRM with recording/notes). Sales productivity boost: no manual dialing, instant customer context, automated activity tracking. Setup: usually API integration (£100-500 setup or DIY with provider documentation). Essential for: sales teams, customer service teams, businesses tracking all customer interactions.
Accounting software (Xero, QuickBooks): Less common integration but valuable for some businesses. Use case: Click client name in accounting software → automatically dial their number. Call tracking per client (hours spent on calls billable to that client). Mostly for: professional services (solicitors, accountants, consultants) billing time by client. Check integration availability before choosing VoIP provider if this matters to your workflow.
Week 1-2: Planning & ordering: Define requirements (how many users, which features needed, desk phones vs softphones). Get 3 provider quotes (compare pricing, features, contract terms). Check broadband adequacy (speed test, calculate VoIP bandwidth needed). Order VoIP service and any hardware (desk phones, headsets). Port existing phone numbers (initiate number porting process 10-15 days lead time). This planning phase critical - rushing leads to wrong provider choice or inadequate infrastructure.
Week 3: Installation & configuration: Hardware arrives (desk phones, any additional routers if needed). Provider provisions service (creates user accounts, assigns numbers). Configure auto-attendant (record greetings, set up routing rules). Test pilot users (2-3 staff test service before full rollout). QoS configuration on router (prioritize VoIP traffic). Identify and fix any issues while limited impact (better than discovering problems after full rollout).
Week 4: Rollout & training: Deploy to all users (configure desk phones or install softphone apps). Staff training (how to make/transfer calls, voicemail access, mobile app use). Run parallel with old system 1-2 weeks (safety net if issues discovered). Number porting completes (business numbers moved to new system). Switch off old system. Post-implementation support (dedicated time for user questions first week). Total timeline: 4-6 weeks from decision to full operation (don't expect instant migration).
Inadequate bandwidth planning: Calculate VoIP needs after signing contract, discover broadband insufficient. Fix requires broadband upgrade (delays VoIP rollout, additional cost). Avoid: test broadband before ordering VoIP, calculate bandwidth requirements (number of concurrent calls × 100kbps), upgrade broadband first if needed. Example mistake: 20-person office on FTTC 40/10Mbps (only 10Mbps upload). VoIP needs 3Mbps for 15 concurrent calls + normal internet use = insufficient. Upgrade to FTTP 100/100 should precede VoIP deployment.
Poor QoS configuration: Install VoIP without configuring router QoS, calls work initially but become choppy during large file downloads/uploads. Users blame VoIP quality when actually router configuration issue. Fix: configure QoS before going live (reserve bandwidth for VoIP, test under load). Many businesses skip this step thinking modern fast broadband doesn't need QoS - wrong. Even 100Mbps connection needs QoS to prioritize real-time traffic over bulk transfers.
Insufficient training: Deploy VoIP with 10-minute group training, expect staff to figure it out. Result: calls not transferred correctly (hung up on customers), voicemail not checked (messages missed), mobile apps not used (defeats remote working purpose). Solution: Hands-on training per user (30 minutes individual time showing their specific use case). Quick reference cards at desks. Dedicated support week 1 (someone available immediately for questions). Training time investment prevents user frustration and ensures adoption.
We'll recommend the right VoIP provider, configure auto-attendant and routing, handle number porting, and ensure proper QoS setup.
Get Help →Keeping business numbers (10-15 days process), port requirements, avoiding number loss, temporary vs permanent forwarding, and porting failures.
Timeline: Standard UK number port takes 10-15 working days from request to completion. Breakdown: Port request submitted → Old provider validates (2-3 days) → Port scheduled (5-10 days notice) → Port completes on scheduled date (usually midnight). Cannot be rushed - regulatory process with mandated timelines. Plan accordingly when switching providers or moving to VoIP. Don't expect instant number transfer.
Who initiates: New provider initiates port (NOT old provider - common mistake). You request port from new VoIP provider, they contact old provider with porting authorization. Never cancel old service before port completes or number lost permanently. Old provider cannot refuse legitimate port request (Ofcom regulations prevent anti-competitive blocking). If old provider delays beyond regulatory timeline, escalate to Ofcom.
Information needed: Exact account holder name (must match old provider records exactly - company name, not trading name). Account number from old provider. Billing address registered with old provider. Porting Authorization Code (PAC) for mobile numbers or equivalent for landlines. Small discrepancy (e.g., "Ltd" vs "Limited") can delay port 5-10 days while corrected. Get accurate information from old provider before starting port request.
Geographic numbers (01/02): Traditional UK landlines fully portable. Can port to any provider (another landline provider or VoIP). Number stays with you regardless of technology or provider. Geographic number indicates location (0161 = Manchester, 020 = London) - businesses often keep for local presence even when moving offices. Port success rate high (95%+) if information correct.
Non-geographic numbers (0800, 0300, 0845): Freephone and national-rate numbers portable between providers. More complex porting (involves number range holder coordination). Timeline: 15-30 days typical (longer than geographic numbers). Worth effort for established business numbers with brand recognition. Cannot port to residential service (business account required with new provider).
Mobile numbers (07): Fully portable between mobile providers. PAC code system (text "PAC" to 65075, receive code instantly). Faster porting (1 working day typical vs 10-15 for landlines). Business mobile numbers same process as personal mobiles. Keep business mobile numbers when changing from one mobile provider to another.
Account mismatch: Most common failure reason. Port request submitted with "ABC Trading" but old provider account under "ABC Limited" = port rejected. Also: wrong address, wrong account number, outstanding balance. Prevention: Contact old provider, request exact account details as registered, use those details precisely. One character difference can fail port. Double-check everything before submitting port request.
Service cancelled too early: Customer cancels old service before port completes = number released back to pool = permanently lost. Never cancel old service yourself. New provider cancels old service automatically as part of porting process. If you cancel early, port fails and number unrecoverable. Wait for port completion confirmation before touching old account.
Number already ported elsewhere: Sometimes business has multiple locations/accounts, number already moved to different account. Or number ported years ago and requesting from wrong provider. Verify: who currently provides service to this number? That's who you port from. Call the number, check who answers/bills, confirm current provider before requesting port.
Temporary forwarding: While port in progress, forward old number to new temporary number or mobile. Ensures no missed calls during transition. Example: Old number 0161-123-4567 porting to VoIP. New provider gives temporary number 0161-987-6543. Forward old → temp during 10-15 day port process. Cost: £5-15/month forwarding fee (old provider charges). Remove forwarding once port completes.
Permanent forwarding (if port fails): Number cannot be ported (rare cases: very old numbers, specific technical limitations, provider disputes). Alternative: keep minimal service with old provider (£10-20/month cheapest line rental), forward permanently to new number. Update website/stationery with new number but keep old number forwarding for 12-24 months (customer transition period). Eventually retire old number once all customers using new number.
Conditional forwarding: Forward only when busy or unanswered (not all calls). Example: VoIP system as primary, mobile as backup. If VoIP unavailable (internet down), calls auto-forward to mobile. More sophisticated than simple forwarding, requires compatible phone system. Useful for: businesses wanting redundancy without dual-WAN expense. Set up during VoIP deployment as safety net.
Bulk porting: Business with 5-20 numbers can port all simultaneously. Request all numbers together (single port order). They complete on same date (coordinated cutover). Advantage: single migration event. Disadvantage: if one number fails validation, entire batch delayed. Consider: pilot single number first (validate process works), then port remaining numbers. De-risks bulk migration.
Phased porting: Port 2-3 numbers first (test numbers or less critical lines), verify process successful, then port remaining numbers. Timeline longer (spread over 4-6 weeks) but lower risk. Example: Port direct lines first, keep main reception number on old system as safety net. Once direct lines working perfectly on VoIP, port main number. Reduces business impact if issues discovered.
Number rationalization opportunity: Migration good time to audit which numbers actually needed. Many businesses accumulate unused numbers over years. During porting: identify active vs inactive numbers, port only active numbers, save £15-25/month per unused number eliminated. Example: Company has 10 numbers, audit reveals only 6 actively used. Port 6, let 4 die = £60-100/month saving ongoing.
New provider charges: Many VoIP providers include porting free (competitive market). Some charge £10-25 per number porting fee. Ask explicitly before ordering - "Is number porting included or extra?" Get written confirmation. Porting fee usually one-time (not recurring). If provider charges porting fee, often waived on 24+ month contracts (negotiating point).
Old provider charges: Cannot legally charge for releasing number (Ofcom rules). May charge early termination fee if leaving mid-contract (separate from porting). May charge final month line rental (must pay until port completion date). Warning: some providers claim "admin fees" for porting - usually illegal, challenge these charges. Number is your asset, not provider's.
Hidden costs: Temporary forwarding during port process (£5-15/month for 1-2 months). Overlapping service charges (paying both old and new for 2-4 weeks during transition). Stationery updates if changing from landline to VoIP (letterhead, business cards showing new number format). Budget £100-200 total incidental costs for number porting beyond service fees. Small compared to keeping established business number.
We'll manage the entire porting process, coordinate with providers, handle the paperwork, and ensure your business numbers transfer without issues.
Get Help →Business firewall requirements (£150-600), port security, VPN encryption, DDoS protection, WiFi security (WPA3), and threat prevention strategies.
Consumer router inadequacy: ISP-provided routers have basic firewalls (block unsolicited inbound connections, nothing more). No application-layer filtering, no intrusion detection, no threat intelligence, minimal logging. Adequate for home use (browse websites, stream Netflix) but insufficient for business (customer data, financial systems, intellectual property protection). Breached consumer router = entire network exposed.
Business firewall capabilities: Application-aware filtering (block malicious websites by category - gambling, malware, phishing). Intrusion prevention (detect and block attack patterns automatically). VPN server built-in (secure remote access for staff). Advanced logging (audit trail for compliance/investigations). Content filtering (restrict non-work websites during business hours). Worth investment: £150-600 hardware protects £50,000+ business assets.
Real attack scenarios: Ransomware delivered via email attachment, spreads across network encrypting all files (£10,000-50,000 ransom + days of downtime). Phishing email tricks staff into revealing banking credentials (fraudulent transfers, direct financial loss). Brute-force attack guesses VPN passwords (attacker gains full network access, steals customer database). All preventable with proper firewall configuration + security policies. Insurance against catastrophic loss.
Entry-level business (£150-300): Brands: Draytek Vigor, Ubiquiti EdgeRouter, TP-Link Business. Features: Stateful firewall, basic VPN server, VLAN support, QoS. Good for: 5-20 users, basic security needs, limited budget. Limitations: No subscription threat intelligence (static rules only), limited intrusion prevention, minimal reporting. Setup: DIY with technical knowledge or £200-400 IT consultant setup. Adequate for low-risk businesses (retail, hospitality, basic services).
Mid-range unified threat management (£300-600): Brands: WatchGuard, SonicWall, Fortinet FortiGate. Features: Next-gen firewall, intrusion prevention, antivirus gateway, content filtering, VPN, detailed reporting. Subscription: £100-250/year for threat intelligence updates. Good for: 20-100 users, compliance requirements (GDPR, PCI-DSS), moderate risk (professional services, finance). Setup: Professional installation recommended (£400-800). Protects against sophisticated threats small businesses typically can't defend against alone.
Enterprise cloud-managed (£50-150/month): Brands: Cisco Meraki, Fortinet FortiGate Cloud, Sophos XG. Features: All UTM features + cloud management dashboard, automatic updates, AI threat detection, 24/7 monitoring. No hardware purchase (rented as service). Good for: Businesses wanting enterprise protection without hardware investment, multiple locations (centrally managed), non-technical businesses needing managed security. Total cost higher over 3-5 years but includes ongoing management and updates.
Default deny inbound: Block ALL unsolicited inbound connections by default. Only allow specific services you've explicitly opened (e.g., VPN port 1194, web server port 443). Never "allow all" inbound - massive security hole. Example bad config: "Allow all traffic from internet to office" = anyone can access anything. Example good config: "Block all inbound except VPN from known IPs" = only authorized connections permitted. Review rules quarterly (remove unused ports, tighten IP restrictions).
Geo-blocking: Block traffic from countries you don't do business with. If UK-only business, block connections from China, Russia, Nigeria, etc. (common attack sources). Reduces attack surface 80-90% immediately. Implementation: firewall geo-IP rules (included in most business firewalls). Exceptions: If you have legitimate international customers/suppliers, whitelist their specific IPs while blocking rest of country. Balances security with business needs.
Outbound filtering: Don't just filter inbound - also control outbound. Block access to known malware command-and-control servers (subscription threat feeds provide lists). Restrict non-work websites (social media, streaming, gambling during work hours). Prevent data exfiltration (limit outbound file uploads to approved cloud services only). Example: Staff PC infected with malware tries contacting attacker server - outbound filter blocks connection, malware can't function. Defence in depth approach.
Strong authentication: Require certificate-based VPN authentication (not just username/password). Password alone = vulnerable to brute force attacks (attacker tries 10,000 passwords until one works). Certificate + password = two-factor authentication (attacker needs both certificate file AND password). Issue unique certificates per user (revoke individual access easily). Setup: 2-4 hours initial configuration, £300-600 IT consultant if no in-house expertise. Essential for remote access security.
Split-tunnel vs full-tunnel: Split-tunnel: Only business traffic goes through VPN, general internet direct (faster, less bandwidth). Full-tunnel: ALL traffic through VPN including general browsing (slower but more secure). Recommendation: Full-tunnel for businesses handling sensitive data (ensures all remote worker traffic monitored/filtered). Split-tunnel acceptable for low-security environments wanting better performance. Configure per-user based on role and data access level.
VPN logging and monitoring: Enable detailed VPN logging (who connected when, from where, what they accessed). Review logs weekly for anomalies (connections from unexpected countries, unusual hours, excessive data transfer). Alerts for failed login attempts (5+ failures = potential brute force attack, block that IP). Compliance requirement for many industries (GDPR, PCI-DSS require access audit trails). Logging costs nothing but provides invaluable security visibility and incident investigation capability.
WPA3 encryption mandatory: Never use WEP (crackable in minutes) or WPA (vulnerable). WPA2 minimum, WPA3 preferred (latest standard, strongest security). WiFi password requirements: 16+ characters, mix of upper/lower/numbers/symbols, changed quarterly. Example bad: "Company2024" (easily guessed). Example good: "Tr4nS!tG@teWay#2024" (complex, unique). Don't write password on whiteboard visible to visitors - issue temporary guest access instead.
Separate guest network: Never let visitors/customers on main business WiFi. Create isolated guest network (separate SSID, different password, changed weekly). Guest network restrictions: Internet access only (can't access internal servers, printers, file shares). Bandwidth limits (prevent guest streaming consuming business bandwidth). Time limits (4-hour session maximum, automatic disconnect). Protects business network from untrusted devices (visitor laptop with malware can't spread to business systems).
WiFi access control: MAC address filtering (whitelist approved devices only). Device registration process (IT approves device before granting WiFi access). Hidden SSID (network name not broadcast - reduces casual connection attempts). 802.1X authentication (certificate-based WiFi login - enterprise-grade security). Overkill for 5-person office but essential for 50+ users or high-security environments (legal, medical, finance). Scale security to business risk level and compliance requirements.
What is DDoS: Distributed Denial of Service attack - thousands of compromised computers flood your internet connection with junk traffic. Your connection becomes saturated (all bandwidth consumed by attack traffic), legitimate users can't access your services. Common targets: e-commerce sites (take offline during attack), professional services websites (reputation damage), competitive businesses (sabotage). Attack costs attacker £50-200, costs victim thousands in lost revenue + mitigation.
Basic DDoS mitigation: Enable SYN flood protection on firewall (drops malicious connection attempts). Rate limiting (maximum connections per IP per second). ISP-level filtering (contact provider during attack, they can block attack traffic upstream). Cloud-based DDoS protection (Cloudflare £20/month, AWS Shield - traffic filtered before reaching your connection). Most small businesses don't need dedicated DDoS protection (attacks rare, ISP help sufficient). E-commerce/online businesses should consider cloud protection (attacks more likely, downtime costly).
Bandwidth abuse prevention: Even without deliberate attacks, poorly configured systems waste bandwidth. Prevent: Unlimited cloud backup during business hours (schedule overnight), staff streaming video (content filter or QoS limits), malware uploading files (outbound monitoring), poorly configured software auto-updates consuming full bandwidth. Monitor bandwidth usage (graphs showing GB per day), investigate spikes (sudden 10x increase = problem). PRTG, LibreNMS (free monitoring tools) identify bandwidth hogs before impacting business operations.
GDPR network security: If processing customer personal data (names, addresses, payment details), GDPR requires "appropriate technical measures". Means: Firewall protecting customer database, encrypted VPN for remote access, logging access to personal data, regular security updates. Non-compliance fines: up to 4% annual turnover or £17.5M (whichever higher). Audit question: "Show us your firewall logs proving only authorized access to customer database." Can't answer = compliance failure. Business firewall + proper logging = evidence of compliance.
PCI-DSS for card payments: Take card payments online/in-person = PCI-DSS compliance required. Requirement 1: "Install and maintain firewall configuration to protect cardholder data." Requirement: Firewall between internet and payment systems, no direct access to payment terminal network, quarterly firewall rule reviews, penetration testing. Many small businesses ignore this (until breach occurs, then face fines + card scheme penalties + customer lawsuits). Proper network segmentation (payment systems isolated on separate VLAN) essential.
Cyber insurance requirements: Business cyber insurance increasingly requires security controls. Application questions: "Do you have business-grade firewall? Updated within 30 days? VPN with strong authentication?" Answer "no" = higher premiums or coverage denial. Claim denied if breach resulted from inadequate security (no firewall, default passwords, no updates). £300 firewall investment enables £50,000 cyber insurance coverage. Insurance providers audit security controls annually - maintain evidence (firewall config backups, update logs, penetration test reports).
We'll recommend the right firewall for your business, configure security rules, set up VPN access, and ensure compliance with GDPR/PCI-DSS requirements.
Get Help →4G/5G backup routers, automatic failover configuration, mobile data plans for backup, bonded connections, and testing backup connectivity.
4G backup advantages: 90%+ UK coverage, reliable indoor signal, mature technology, affordable hardware (£150-300), stable speeds (20-80Mbps), works on battery power during office power cuts. Cost: £30-50/month unlimited data. Best for: Most businesses, reliable backup solution, proven technology. Adequate speeds for essential operations during primary outage (email, cloud apps, VoIP all functional).
5G backup advantages: Faster speeds (100-300Mbps), lower latency (20-40ms vs 30-50ms), future-proof. Disadvantages: Limited coverage (40-50% UK), poor indoor penetration (thick walls block signal), requires external antenna (£100-300 extra), less mature. Cost: £40-70/month unlimited. Best for: Locations with confirmed 5G coverage, businesses needing high-speed backup (video conferencing must continue during outage), future expansion plans.
Recommendation: 4G for most businesses (reliability > speed for backup). 5G if confirmed excellent signal and business requires high-bandwidth backup. Test signal strength thoroughly before committing - walk around office with phone, check 4G/5G speeds in different rooms. Signal varies dramatically within same building.
Dual-WAN router setup: Primary connection (FTTP) + backup connection (4G) both connected to dual-WAN router. Router monitors primary constantly (ping test every 10 seconds). Primary fails → automatic switch to 4G within 30-60 seconds. Primary restored → automatic failback after stability confirmed. Users experience brief interruption (like WiFi reconnection) not complete outage. Essential for: Call centres, e-commerce, businesses where even 10-minute outage costly.
Router recommendations: Business dual-WAN routers: Draytek Vigor (£200-400), Ubiquiti EdgeRouter (£150-250), Peplink Balance (£400-800). Features needed: Automatic health checking, configurable failover sensitivity, per-application routing (critical apps via primary, bulk downloads via backup). Don't use consumer routers with "backup WAN" feature - unreliable failover, poor monitoring. Invest properly or failover won't work when needed.
Testing failover: Monthly test essential - disconnect primary, verify backup activates, test critical applications (VoIP calls, payment processing, cloud apps), measure failover time. Common issues discovered during testing: Backup SIM not activated (sits dormant for months, fails when needed), router firmware outdated (bugs in failover logic), 4G signal strength inadequate (works sometimes, not reliably). Test reveals problems in controlled environment vs discovering during real emergency.
Unlimited vs capped plans: Unlimited (£40-60/month) = no overage risk, use freely during outage. Capped (100-200GB for £25-35/month) = cheaper but risky (extended outage consuming full allowance = expensive overage or throttling). Recommendation: Unlimited for backup (£10-15/month premium worth peace of mind). Backup activated during 8-hour primary outage, heavy use during that period - don't want to worry about data limits during emergency.
Business vs consumer plans: Business mobile data includes better support, static IP options (some providers), priority network access during congestion. Consumer plans cheaper but no SLA, no business support. For backup connectivity: consumer plan usually adequate (not using daily, just emergency). Save £10-20/month on consumer plan vs business equivalent. Only choose business plan if need static IP for backup or want support SLA.
Total backup cost analysis: Hardware: £250 dual-WAN router + £200 4G router = £450 one-time. Monthly: £40 unlimited 4G = £480/year. Total year 1: £930. Ongoing: £480/year. Protects against: 2-3 outages yearly averaging 4 hours each = 12 hours downtime prevented. If downtime costs £200/hour = £2,400/year saved. ROI: 2.6x first year, 5x ongoing. Justified for most connectivity-dependent businesses.
We'll configure automatic failover, test your 4G/5G signal strength, and ensure seamless backup connectivity.
Get Help →Calculate your business bandwidth needs: retail, professional services, e-commerce, call centres, creative agencies, and scaling calculations.
Typical usage: POS terminals (5-10 devices), inventory management, email, cloud accounting, light web browsing. Peak usage: 10-20 concurrent processes. 50Mbps handles small retail (1-5 staff), 100Mbps comfortable for 10-20 staff. Upload speed: 10-20Mbps sufficient (cloud backup overnight, occasional large file uploads).
Calculation: POS system: 2Mbps per terminal × 5 terminals = 10Mbps. Cloud accounting: 3Mbps. Email/browsing: 10 staff × 1Mbps = 10Mbps. CCTV upload: 5Mbps. Overhead/buffer: 30%. Total: (10 + 3 + 10 + 5) × 1.3 = 36.4Mbps minimum. Recommendation: 50-80Mbps connection for comfort margin during peak Christmas trading.
Accountants, solicitors, consultants: Heavy cloud app usage (Office 365, Salesforce, cloud accounting), video conferencing (Teams/Zoom), large file sharing (client documents), secure remote access. 20-50 staff typical. 100Mbps minimum, 300Mbps recommended for 40+ staff. Upload critical: 50-100Mbps for video conferencing quality and large file uploads.
Calculation: Office 365: 30 users × 5Mbps = 150Mbps. Video conferencing: 10 concurrent calls × 3Mbps = 30Mbps. Cloud storage sync: 20Mbps. VoIP: 20 users × 0.1Mbps = 2Mbps. Total: 202Mbps + 30% buffer = 263Mbps. Symmetric 300Mbps connection ideal for professional services with heavy cloud dependency.
Online retailers: Website hosting (if on-premise), order processing systems, inventory updates, payment gateway, customer service, warehouse management. Upload speed critical: product images, database backups, real-time stock updates. Downtime = lost sales. 300Mbps symmetric minimum, 500Mbps-1Gbps for high-volume operations (1,000+ orders/day).
Peak demand planning: Black Friday/Christmas peak: 5-10× normal traffic. If baseline 100Mbps, provision 500Mbps-1Gbps for peaks. Burst capacity essential. Consider: Cloud-hosted website (scales automatically) + leased line for office operations (guaranteed speeds). Cost: Leased line £400-800/month but zero downtime risk vs £150/month business broadband with potential peak slowdowns.
VoIP bandwidth calculation: Each agent: 100kbps per active call. 10 concurrent calls = 1Mbps. 50-agent call centre with 80% concurrent usage: 50 × 0.8 × 0.1Mbps = 4Mbps for voice. Add CRM/systems: 50 users × 3Mbps = 150Mbps. Total: 154Mbps. Provision 200-300Mbps with QoS prioritizing VoIP traffic. Upload: 50-100Mbps for outbound calls and cloud recording.
Quality of Service (QoS) essential: Prioritize VoIP packets over other traffic. Without QoS: staff downloading files slows all calls. With QoS: calls maintain quality even during heavy downloads. Configuration: VoIP priority 1 (highest), CRM priority 2, general browsing priority 3. Business routers (£200-500) include QoS. Consumer routers don't - invest in proper equipment for call centre operations.
Video production, design studios: Massive file transfers (4K video, RAW images), cloud rendering, client presentations, collaborative editing. Individual project files: 50-500GB. Daily uploads/downloads: 200-500GB. 100Mbps upload = 2.2 hours for 100GB file. 500Mbps upload = 26 minutes same file. Time = money in creative industries.
Symmetric speeds essential: Download for assets, upload for deliverables. 1Gbps symmetric: £150-300/month full-fibre vs £800-1,500/month leased line. Full-fibre adequate for most agencies. Leased line justified only if: mission-critical deadlines (broadcast TV), 20+ staff all transferring large files simultaneously, client work requiring guaranteed speeds 24/7. Calculate: will 1Gbps save 10+ hours/week? If yes, worth £200-300/month investment.
Monitoring usage: Most business routers show bandwidth utilization. Target: peak usage 60-70% of capacity. If consistently hitting 80%+, upgrade needed. Free tools: GlassWire (Windows), Activity Monitor (Mac), router admin interface. Check: average usage vs peak usage vs capacity. Sustained 90%+ usage = degraded performance for all users.
Upgrade path: Start 50-100Mbps → grow to 100-300Mbps → eventually 500Mbps-1Gbps. Upgrade triggers: consistent 80%+ usage, video quality complaints, slow cloud app performance, new staff additions. Provider flexibility matters: choose providers offering easy upgrades without engineer visits or £200+ fees. Best: upgrade via phone call, active within 24 hours, £10-30/month cost increase per speed tier.

Get Help →Office 365, Salesforce, cloud accounting bandwidth needs, QoS configuration, and performance optimization.
Microsoft recommends 5Mbps per user for optimal Office 365 experience. 20 concurrent users = 100Mbps minimum. Teams video calling requires 3-5Mbps per participant. OneDrive sync: 5-10Mbps upload for document collaboration. SharePoint: 2-3Mbps per user accessing files simultaneously.
Salesforce bandwidth: 3-5Mbps per concurrent user. 10 sales staff using CRM simultaneously = 30-50Mbps. Upload speed critical for file attachments, document updates, report generation. Poor upload = slow CRM saves, frustrated staff, reduced productivity.
Xero, QuickBooks, Sage Cloud: 2-4Mbps per user. 5 accounting staff = 10-20Mbps. Bank reconciliation, invoice processing, report generation all cloud-based. Slow connection = delays in financial reporting, month-end close takes longer.
Quality of Service (QoS) prioritizes business-critical cloud traffic. Configure router to prioritize: Priority 1 (highest): VoIP, video conferencing. Priority 2: Cloud CRM, accounting. Priority 3: Email, general browsing. Priority 4: Downloads, updates. Without QoS: one staff member downloading large file slows Office 365 for entire team.
We'll diagnose slow cloud apps and recommend bandwidth upgrades or QoS configuration.

Get Help →VoIP international rates vs traditional ISDN costs. Massive savings for exporters and international businesses.
Traditional ISDN international: Europe £0.15-0.35/min, USA £0.20-0.40/min, India/Asia £0.30-0.70/min. VoIP international: Europe £0.01-0.03/min, USA £0.01-0.02/min, India/Asia £0.02-0.05/min. Savings: 80-95% on international calls. Business making 500 international minutes/month saves £75-200/month switching to VoIP.
VoIP providers offer unlimited international bundles: £10-20/month covers 60+ countries. Includes USA, Canada, Europe, Australia. Perfect for businesses with regular international calls. Calculate: if making 100+ international minutes/month, unlimited bundle pays for itself.
12 vs 24 vs 36 month contracts, early exit fees, rolling monthly options, price increase clauses, and auto-renewal terms.
12-month contracts: Standard term, moderate early exit fees (£150-250). Flexibility to switch annually. 24-month contracts: Better pricing (10-15% discount), higher exit fees (£300-500). 36-month contracts: Best pricing (20-25% discount) but long commitment, exit fees £400-600. Match contract length to office lease term.
Most providers include RPI + 3.9% annual price increases mid-contract. £50/month can become £60+ by year 3. Fixed-price contracts rare but worth seeking. Read small print: some providers cap increases at 5-10% annually, others unlimited.
30 days notice, zero exit fees. Premium pricing: 10-20% more than fixed contracts. Worth it for: short-term office space, uncertain business future, likely relocation. Flexibility costs £7-15/month extra but avoids £300-600 exit fees if circumstances change.
We'll review contract terms and recommend optimal length for your situation.
Get Help →Uptime percentages, fix times, compensation clauses, SLA exclusions, and what to look for in business broadband contracts.
99% uptime = 87 hours down/year (7.2 hours/month). 99.9% = 8.7 hours down/year (43 minutes/month). 99.99% = 52 minutes down/year (4 minutes/month). Residential broadband: no SLA. Business broadband: 99-99.9% typical. Leased lines: 99.9-99.99% guaranteed.
Standard business: 24-48 hours fix time. Premium business: 6-12 hours fix time. Leased line: 4-6 hours fix time. Measured from fault reporting to resolution. Missed SLA targets trigger compensation (usually service credits, not cash).
Read exclusions carefully: Planned maintenance (often excludes overnight), force majeure (weather, strikes), customer equipment failures, power cuts. Some SLAs exclude weekends/holidays from fix time calculations. Best SLAs: minimal exclusions, 24/7/365 coverage, proactive monitoring.
FTTP vs FTTC, copper phase-out 2027, choosing scalable solutions, planning for growth, and avoiding technology dead-ends.
FTTC (fibre to cabinet): Uses copper for final connection, speeds 80Mbps max, being phased out. FTTP (fibre to premises): Pure fibre, speeds 100Mbps-10Gbps, future-proof. Always choose FTTP when available. Copper network shutting down 2027 - don't invest in dying technology. FTTC contracts ending after 2027 problematic.
If you need 100Mbps today, provision 150Mbps connection. Headroom allows for: Business growth, new applications, unexpected usage spikes. Easier to use existing capacity than upgrade mid-contract. Cost difference minimal: £5-10/month extra prevents future bottlenecks.
Traditional broadband: asymmetric (100Mbps down, 20Mbps up). Cloud-first businesses need symmetric speeds (100Mbps both ways). Uploads crucial for: Cloud backups, video conferencing, VoIP, file sharing. Invest in symmetric connection now to avoid upgrade later.
2027: Copper network shutdown complete. All businesses must migrate to FTTP/5G/leased line. VoIP mandatory (ISDN discontinued). Plan migration now: test VoIP quality, provision FTTP, update systems. Don't wait until 2027 deadline rush. Early adopters get better deals, avoid installation delays.
