The UK’s copper telephone network is being retired in phases. For many SMEs, that means more than a technical upgrade — it is a deadline to review how you buy voice services, how resilient your connectivity is, and whether your contracts still make sense when the underlying network changes.
Why Openreach is retiring copper
Copper lines were designed for voice decades ago. Fibre and digital services deliver higher capacity, lower maintenance and a clearer path for future demand. Openreach’s programme to stop selling copper-based products and migrate premises to fibre-based alternatives is already under way; the exact timeline for your building depends on exchange and cabinet rollout in your area.
If you still rely on a traditional phone line for alarms, lift lines or card machines, treat the switch-off as a procurement project — not a last-minute IT ticket.
What to check first
Start with an inventory: which services still use PSTN or ISDN lines, which broadband products are copper-backed, and which suppliers have notified you of a migration. Finance and operations teams should align on renewal dates so you are not forced into expensive interim fixes when copper products are withdrawn.
Planning your next step
In many cases, full fibre or SOGEA-style broadband plus a modern VoIP platform replaces legacy voice cleanly. Where fibre is not yet available, interim wireless or hybrid options may apply — but lead times vary, so early planning beats emergency spend. If you are comparing business energy and connectivity together, ask your broker how contract end dates line up so you can avoid paying twice for overlapping services.
