Sources and assumptions

  • Prices use the Ofgem price cap for 1 July to 30 September 2026: 26.11p per kWh, the average for Direct Debit customers in England, Scotland and Wales. Northern Ireland is not covered by the cap.
  • Energy use comes from Which? lab tests of typical models. Your own model may use more or less.
  • The daily standing charge (57.19p a day) is paid whatever you use, so it is not included.

These are estimates. Your bill depends on your tariff, your region and how you use the appliance.
