How we work it out
Cost per hour = watts ÷ 1,000 × share of time at full power × price per kWh. For a 1,200W halogen heater at 100%: 1,200 ÷ 1,000 × 1 × 26.32p = 32p.
The wattage on this page is our estimate from typical models on sale, as we couldn't find an independent published figure. Your own appliance may differ, so check its rating plate or energy label for the most accurate figure.
