A fan’s wattage shows how much electrical power it uses while operating. To convert watts into kilowatt-hours, divide the wattage by 1,000 and multiply it by the number of hours the fan runs.
Use this calculation:
Fan wattage ÷ 1,000 × hours used = electricity used in kWh
For example, a 45W fan running for eight hours uses:
45W ÷ 1,000 × 8 hours = 0.36kWh
You can usually find your fan’s wattage on a label underneath or behind the appliance, on the power adaptor, in the instruction manual or within the manufacturer’s product information.
The wattage shown may represent the fan’s maximum rated power. Running it at a lower speed may use slightly less electricity, while features such as heating or cooling elements can increase consumption significantly. For the most accurate fan running cost UK estimate, use the wattage displayed on your specific model rather than relying only on the general averages above.

🌀 How Much Does a Tower Fan Cost to Run in the UK?
A typical 50W tower fan costs approximately 1.31p per hour to run, based on an electricity rate of 26.11p per kWh.
Our guide to the best tower fans for studio flats UK compares slim models designed to provide strong airflow without occupying much floor space.
That works out at around:
- 5.22p for four hours
- 10.44p for eight hours
- 31.33p for 24 hours
- £3.13 per month when used for eight hours every day
- £9.40 per month when operated continuously

❄️ Fan vs Air Conditioner Running Cost
Fans and portable air conditioners work differently. A fan moves air around the room and helps you feel cooler, while an air conditioner actively lowers the air temperature.
Our portable AC vs cooling fan comparison explains when the stronger cooling of an air conditioner may justify its considerably higher running cost.
This difference has a major effect on electricity use.
| Appliance | Example Power | Cost Per Hour | Cost for 8 Hours |
|---|---|---|---|
| Desk fan | 30W | 0.78p | 6.27p |
| Tower fan | 50W | 1.31p | 10.44p |
| Portable air conditioner | 1,200W | 31.33p | £2.51 |
The fan running cost UK households face is therefore substantially lower than the cost of operating a portable air conditioner for the same period.
Based on these example wattages, a 1,200W portable air conditioner costs approximately 40 times more to run than a 30W desk fan.
For a small flat or studio flat, a fan is usually the cheaper option when air movement is enough to make the room comfortable. A portable air conditioner may provide stronger cooling during extreme heat, but its higher power consumption makes it considerably more expensive to use for long periods.
🏠 Are Fans Efficient for Cooling a Studio Flat?
Fans don’t actually lower the room temperature. Instead, they circulate air and increase evaporation from your skin, which makes you feel cooler.
For a broader choice of compact models, see our guide to the best cooling fans for studio flats UK.
For studio flats, fans work best when:
- windows are open to allow airflow
- used during evening or night cooling
- positioned near windows or doorways
In a compact home, the low fan running cost UK users typically pay makes regular fan use practical throughout warmer periods.
💡 Tips to Reduce Fan Running Costs
Although fans are already cheap to run, a few small adjustments can help reduce energy usage even further.
Use the lowest effective speed
Higher speeds use slightly more electricity.
Position fans correctly
Place fans near windows to improve airflow across the room.
Use fans with timers
Many modern tower fans include timers that automatically shut the fan off during the night.
