A typical use is an evening of 4 hours, a night of 8 hours or 5 hours to dry a load of washing, and a month is one typical use a day. Heating oil isn't capped, so it uses a national average price, and standing charges are left out.

Heating the whole house with a gas boiler for the same evening costs £1.90 in our Index, and £5.26 with electric heaters or an electric boiler. If you're the only one at home, warming yourself rather than the whole house costs far less.” - > “At this quarter's prices, an air source heat pump costs 44.9p an hour to heat the house in our Index and a gas boiler 47.4p. Last quarter it was the other way round. The gap is 2.5p an hour, and a well set-up system of either kind can do better than these averages.” - > “Whole-house gas heating rose by 3.8p an hour this quarter (8.7%). For the 5kW house in our Index, that's 15p more for a 4-hour evening with the heating on.” ## Releases - **Q4 2026: October to December**, published 15 October 2026. Electricity 26.11p to 26.32p per kWh, gas 7.33p to 7.97p.
