Heating & hot water

The big seasonal costs

Anything that makes heat directly from electricity uses power in kilowatts, not watts. These are the appliances that move a winter bill.

2kW heater running costPer hour, per evening, and against gas central heating.53p an hour at full power
Oil-filled radiator running costWhy thermostat cycling decides the real cost.£1.58 for a 6-hour evening at 50% on-time
Electric blanket running costHeat the bed, not the bedroom.1.3p to pre-heat the bed
Electric shower running costCost per shower for 7.5 to 10.5kW models.33p for 8 minutes at 9.5kW

How these figures are worked out

Every running cost here uses the same two steps: kWh = watts ÷ 1,000 × hours, then cost = kWh × unit rate. The unit rate is Ofgem's price cap average for Great Britain for customers on a standard variable tariff paying by Direct Debit. Ofgem's electricity figures for this period include no VAT: the government removed VAT from domestic electricity from 1 October 2026 to 31 March 2027. Gas figures include 5% VAT.

We leave out the daily standing charge (54.83p a day at the cap), because you pay it whether an appliance is on or off. The UK electricity price page explains the unit rate, the standing charge and how they make up a bill.

Wattages and kWh-per-use figures in the tables are examples within the usual range for each appliance, and are labelled as such. Your own appliance label, or a plug-in energy monitor, will always be more accurate. See our methodology.

Not in Great Britain? Northern Ireland is not covered by the Ofgem price cap. Use the electricity cost calculator with your own rate. For France, see nos pages en français.
