How Much Does It Cost to Run a Desk / Standing Fan? (UK 2026)
Based on the active UK Ofgem price cap of 24.5p per kWh (1 January 2026 – 31 March 2026).
A typical 45W desk / standing fan costs £0.01 per hour of continuous use at current UK electricity rates (24.5p/kWh). For typical daily usage (6 hours continuous cooling during summer afternoons/nights (~0.27 kWh/day)), it costs approximately £0.07 per day or £24.88 per year.

How to Save Money Running a Desk / Standing Fan
- Turn fans off when leaving the room; fans cool people via skin sweat evaporation (wind chill effect), not room air temperature.
- Place a bowl of ice or cold water directly in front of the fan to generate an evaporative cooling breeze.
- Point the fan out of a window in the evening to exhaust trapped daytime heat, pulling cool night air through opposite windows.
- Clean dust off the fan blades at the start of summer; dusty blades drag aerodynamically and reduce air movement by 20%.
Alternative Appliances Compared
vs. Portable Air Conditioner
View running cost →A fan draws 45W compared to 1100W for an air conditioner—meaning running an air conditioner costs roughly 25 times more.
vs. Dehumidifier
View running cost →In humid heat, lowering humidity with a dehumidifier (300W) improves comfort, but a fan (45W) provides instant personal relief.

Frequently Asked Questions: Desk / Standing Fan Electricity Costs
How much does it cost to run a desk fan all night (8 hours) in the UK?â–¾
A 45W fan running for 8 hours consumes 0.36 kWh. At 24.5p/kWh, that costs approx. 8.8p per night (around £2.65 per month of summer heat).
Does leaving a fan on in an empty room cool it down?â–¾
No! Fans do not change air temperature; the electric motor actually releases a tiny amount of heat into the room. Fans only create a wind chill effect on human skin.
Is a ceiling fan more efficient than a pedestal fan?â–¾
Ceiling fans move much larger volumes of air at lower rotational speeds, covering entire rooms for around 30W to 65W with superior efficiency.
How does the speed setting affect electricity use?â–¾
Running a fan on speed 1 (low) draws approx. 25W–30W, while speed 3 (high) draws 45W–55W—roughly half the running cost on low.
How much cheaper is a fan compared to an air conditioner?â–¾
A 45W fan costs around 1.1p per hour to run in the UK, whereas a 1100W portable air conditioner costs approx. 27p per hour—making the fan 95% cheaper.
