How Much Does It Cost to Run a Electric Fireplace in the UK? (2026)
An electric fireplace is a 1,500 watt space heater with a flame effect. The flame display alone uses 10 to 20 watts, so running it for ambience without heat costs almost nothing.
A typical electric fireplace (1,500 W) costs £0.39 per hour, or about £46.80 per month at 4 hours a day in United Kingdom. Expensive to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (750 W) | £0.20 | £0.78 | £23.40 | £284.70 |
| Typical (1,500 W) | £0.39 | £1.56 | £46.80 | £569.40 |
| High (1,500 W) | £0.39 | £1.56 | £46.80 | £569.40 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 4 h/day ≈ 2,190 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 fireplace costs £0.39 per hour and about £569.40 per year at 4 hours a day. Each £1.00 of electricity buys roughly 2.6 hours of use.
How to lower the cost of running a electric fireplace
- Use the flame effect without the heater when you only want the look.
- Set the built-in thermostat so the heater cycles.
- Close doors to keep heat in the room it is warming.
In standby it draws about 1 W, which adds roughly 9 kWh (£2.28) per year if it is never unplugged.
