Power Ladder
Drag a slider from a firefly to a supernova and see what uses or produces that much power, from a kettle to a power station.
Open the Power LadderHow the costs are worked out
Cost = kilowatts × hours × price per kWh
One kilowatt running for an hour costs 26.3p at 26.32p per kWh. For example, a 3 kW kettle running for 2 minutes uses 0.10 kWh, which costs 2.6p.
Yearly figures assume the typical use shown for each appliance, so your own bill depends on how often you use it. Every appliance page has sliders to change the power, the time and the rate.
Electricity rate: Ofgem energy price cap, 1 October to 31 December 2026, Great Britain average, Direct Debit, default tariff: 26.32p per kWh. Your own tariff and region may differ, so change the rate on any appliance page to match your bill. Appliance figures are typical estimates; your appliance's energy label or manual is more accurate.
