* Typical use shown under each figure, 30 days, at the Ofgem price cap (26.32p/kWh). Typical means the seller does not publish the power, so we use a typical figure for that kind of appliance. Recalculated every update.
- Running cost: What each one costs per hour and per month at the Ofgem price cap (26.32p/kWh). Watt for watt, every electric heater costs the same to run: the one that saves money is the right size and switches itself off.
- Controls: Thermostats, timers, weekly schedules, eco modes and Wi-Fi score highest: they are what actually cuts the bill.
- Safety: Tip-over and overheat protection, and splash protection (IP24) for bathrooms.
- What buyers say: Amazon UK sales and what buyers repeat in their reviews, summarised in our own words. Newer models with few reviews score lower until they have them.
We don't test products at home: we combine manufacturers' specifications, Amazon UK listings and buyer feedback with the running-cost maths. How we compare.
