Equipment Upgrades That Pay Back

Brochures quote double-digit savings; installed projects often land in the middle. This guide shows how to sanity-check payback on chillers, ovens and other kit using conservative assumptions.

Next step: If you use under about 50,000 kWh a year, you can get a quote in under 90 secs online — fast, no obligation. Bigger supply, half-hourly metering, or prefer chat? Use the contact page.

High-ROI Upgrades

Upgrade payback depends on run-hours, tariff and how tired the old kit is—warehouse drives, extraction fans and kitchen plant often top the list for SMEs. Cross-check with behavioural savings, hospitality loads and lighting projects so you fund the right job first.

1. Variable Speed Drives (VSDs) on Motors

• Energy saving: 20-50%
• Payback: 2-4 years
• Best for: Motors running continuously or with varying loads

2. High-Efficiency Refrigeration

• Energy saving: 30-40% vs 10+ year old units
• Payback: 3-5 years
• Critical for: Cafes, restaurants, shops with chillers

Lower Priority

Solar PV for small businesses:

• Typical cost: £4,000-£8,000 for 4kW system
• Annual generation: ~3,400 kWh
• Annual saving: £550-£750
• Payback: 7-12 years (too long for most small businesses)

Battery storage: Rarely pays back for under 50k kWh businesses. Skip it.

The ROI Test

Before any equipment upgrade, calculate:

Payback (years) = Upgrade Cost / Annual Energy Saving

Under 3 years: Usually worth it
3-5 years: Consider it
Over 5 years: Probably skip unless equipment needs replacing anyway
