How to lower the cost of running an electric kettle

Electric kettles are one of the most efficient ways to boil water because the element sits directly in the water and the kettle switches off as soon as it boils. A full 1.7-liter kettle uses roughly 0.15–0.2 kWh per boil. Our default assumes about 6 minutes of boiling a day.

  • Boil only the water you need — overfilling is the biggest waste.
  • Use a variable-temperature kettle for tea and coffee that don't need a full boil.
  • Descale regularly; mineral build-up slows heating.
