How Much Does It Cost to Run a Ceiling Fan in the UK? (2026)
Ceiling fans do not cool the air, they cool people through air movement. At 15 to 90 watts they cost a tiny fraction of an air conditioner, which is why the best strategy is to run both and raise the AC thermostat.
A typical ceiling fan (50 W) costs £0.013 per hour, or about £3.12 per month at 8 hours a day in United Kingdom. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (15 W) | £0.004 | £0.031 | £0.94 | £11.39 |
| Typical (50 W) | £0.013 | £0.10 | £3.12 | £37.96 |
| High (90 W) | £0.023 | £0.19 | £5.62 | £68.33 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 8 h/day ≈ 146 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 ceiling fan costs £0.013 per hour and about £37.96 per year at 8 hours a day. Each £1.00 of electricity buys roughly 76.9 hours of use.
How to lower the cost of running a ceiling fan
- Turn the fan off when you leave the room. It only helps if someone is there to feel the breeze.
- Set the blades to spin counterclockwise in summer and clockwise at low speed in winter.
- DC motor fans use about 70 percent less power than older AC motor models.
- Fans with built-in lights add 10 to 40 watts when the light is on.
