Fan Running Cost UK: How Much Electricity Do Fans Use?
Fan running cost UK is a common question for people trying to stay cool without increasing their electricity bills. If you live in a studio flat or small apartment, fans are one of the cheapest appliances you can run during warm weather.
With energy prices still high in the UK, many people wonder whether running a fan all day will noticeably increase their electricity bill. If you live in a studio flat or small apartment, fans are often one of the most affordable ways to stay cool during warmer months.
The good news is that fans are extremely cheap to run compared with air conditioners or heaters. In this guide, we’ll break down exactly how much it costs to run a fan in the UK and compare the running costs of different fan types.
Understanding fan running cost UK helps you estimate how much electricity a cooling fan will add to your monthly energy bill.
How Much Electricity Does a Fan Use?
Most electric fans use between 20 watts and 75 watts of power depending on their size and design.
Typical power usage:
- Small desk fan: 20–35 watts
- Tower fan: 40–60 watts
- Large pedestal fan: 50–75 watts
For comparison, portable air conditioners often use 900–1500 watts, which is dramatically higher.
This is why fans are one of the most energy-efficient cooling options for small flats. When comparing appliances, the fan running cost UK is dramatically lower than running heaters or portable air conditioners.
Average Electricity Cost in the UK
According to Ofgem, the UK energy price cap determines the maximum electricity rates suppliers can charge households.
As of 2026, the UK electricity price cap is roughly:
£0.28 per kWh
Electricity cost is calculated using:
Power (watts) × hours used ÷ 1000 × electricity price
Let’s look at a practical example.
Example: Cost to Run a Desk Fan
A typical 30-watt desk fan running for 8 hours per day.
Calculation:
30W × 8 hours = 240Wh
240Wh ÷ 1000 = 0.24 kWh
0.24 × £0.28 = £0.067
Daily cost:
≈ 7p per day
Monthly cost (30 days):
≈ £2.01 per month
This makes desk fans one of the cheapest appliances you can run in your home.
You can also estimate electricity usage using the Energy Saving Trust electricity calculator.
Cost to Run Different Types of Fans
| Fan Type | Average Power | Daily Cost (8 hours) | Monthly Cost |
|---|---|---|---|
| Desk Fan | 30W | ~7p | ~£2 |
| Tower Fan | 50W | ~11p | ~£3.36 |
| Pedestal Fan | 70W | ~16p | ~£4.70 |
Even larger fans usually cost less than £5 per month when used regularly.
If you’re choosing a cooling solution for a studio apartment, fans remain one of the most cost-effective options available.

Fan vs Air Conditioner Running Cost
Fans are dramatically cheaper to run than air conditioners.

|---|---|---|
| Desk Fan | 30W | ~7p |
| Tower Fan | 50W | ~11p |
| Portable Air Conditioner | 1200W | ~£2.68 |
This means a portable AC unit can cost 20–40 times more to run than a fan.

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 studio flats, fans work best when:
- windows are open to allow airflow
- used during evening or night cooling
- positioned near windows or doorways
