‘Remember that central heating is a lot cheaper to run than an electric heater,’ says John Lawless, a heating expert at BestHeating (opens in new tab). Similarly, an example 3kW convector heater would cost £1.02 per hour to run on full power, £4.08 an evening and £28.56 a week, which shows how a more powerful heater can cost almost £10 extra over a week. Over a four-hour evening, this would be £2.72 (68p x 4 hours), and over a week, £19.04 (£2.72 x 7). For example, a 2kW fan heater would cost 68p an hour to run on full power (34p x 2kW). We've used this figure in the calculations below to illustrate the highest amount it could cost to run an electric heater from October 2022.Įlectric heaters show how much energy they use as their heat output. However, this is set to rise from October when the energy price cap increases the price per pence/kWh of energy to 34p. In November 2021, the national average price per pence/kWh of electricity was 20.33p, according to the Energy Saving Trust (opens in new tab). Electricity prices have gone up drastically in the last year.
