How we worked out the cost

We use a typical figure of 1 kWh per hour for a typical 2.4 kW steam iron, with the thermostat cycling. At 26.32p per kWh, that is 1 × 26.32p = £0.26. Over a week of 2 hours it is £0.53, and over a year £27.37.

These are typical estimates rather than lab measurements. Your appliance may use more or less, so adjust the kWh in the calculator for your own.

25p per kWh£0.25£26.00

40p per kWh£0.40£41.60

How to reduce the cost

  • Iron in batches so the iron is only heated once.
  • Wash at 30°C or 40°C with full loads, as heating water uses most of the energy.
  • Use the highest spin speed to wring out more water, then dry outside or on a rack when you can.
  • Run appliances in an eco mode where available.

Based on the Ofgem price cap of 26.32p per kWh for 1 October to 31 December 2026. Ofgem states these figures do not include VAT from 1 October 2026 to 31 March 2027, because the Government has removed VAT from electricity bills for that period. The standing charge is not included. Source: Ofgem.

How accurate are these figures?

They are estimates for a typical modern appliance. Age, model, settings and how you use it all change the real cost, so treat them as a guide and check your appliance’s energy label for a precise figure.
