Overview
- New coverage highlights a Which? graphic showing kettles draw about 3,000W, far more than many common appliances.
- A full kettle of roughly 1.5 litres can take up to five minutes to boil, creating short but significant power spikes.
- Which? estimates typical kettle use costs around £39 per year, based on specific daily boiling assumptions.
- Households are urged not to exceed about 3,000W from one socket because overloading can overheat plugs and risk fires.
- Advice to cut use includes boiling only what you need and regular descaling, while Currys says some models claim up to 20% less energy per boil with features like rapid boil or keep-warm.
