How Much Does It Cost to Run a Electric Kettle in the UK? (2026)
Kettles draw a lot of power but for only a few minutes. Boiling a litre of water takes about 0.1 kWh regardless of kettle wattage; a higher wattage kettle just does it faster.
A typical electric kettle (2,000 W) costs £0.52 per hour, or about £2.34 per month at 0.15 hours a day in United Kingdom. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (1,500 W) | £0.39 | £0.058 | £1.75 | £21.35 |
| Typical (2,000 W) | £0.52 | £0.078 | £2.34 | £28.47 |
| High (3,000 W) | £0.78 | £0.12 | £3.51 | £42.70 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.15 h/day ≈ 110 kWh per year.
In the UK, with electricity at £0.26 per kWh (source: Ofgem price cap 1 Jul–30 Sep 2026, 2026-07), a typical electric kettle costs £0.52 per hour and about £28.47 per year at 0.15 hours a day. Each £1.00 of electricity buys roughly 1.9 hours of use.
How to lower the cost of running a electric kettle
- Boil only the water you need. Filling the kettle for one cup doubles or triples the cost.
- Descale regularly. Limescale on the element slows heating.
- A kettle with a keep-warm function can use more over a day than boiling twice.
- Kettles are more efficient than boiling water on an electric stovetop.
