What can UK SMEs typically save?

UK small businesses spending around £8,000 per year on electricity can typically save between £800 and £2,400 annually - equivalent to 0.3 to 1.0 tonnes of CO2e - through a combination of LED lighting upgrades, smart energy controls, and off-peak scheduling. Businesses with higher energy use see proportionally larger returns.

On gas and heating, improving insulation and reducing thermostat settings by just 1°C typically cuts spend by 8-25% per year, with payback periods under 18 months for most behavioural measures. A business spending £3,000 per year on gas could realistically save £240 to £750 annually.

Business travel is often the fastest-payback area: flexible working policies and a shift from air to rail cost nothing to implement and can reduce travel emissions by 10-35%. A business spending £5,000 per year on travel could cut that by £500 to £1,750.

All estimates use the DESNZ 2024 greenhouse gas conversion factors and standard UK electricity and gas unit rates. Results are indicative - actual savings will vary based on your current contracts, equipment age, and operational patterns.
