How Much Does It Cost to Run a Air Compressor in the UK? (2026)
A workshop compressor draws 1,000 to 2,500 watts while filling the tank, then sits idle until pressure drops. Intermittent use makes it cheap; leaks that keep it cycling are the hidden cost.
A typical air compressor (1,500 W) costs £0.39 per hour, or about £2.93 per month at 0.25 hours a day in United Kingdom. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (1,000 W) | £0.26 | £0.065 | £1.95 | £23.73 |
| Typical (1,500 W) | £0.39 | £0.098 | £2.93 | £35.59 |
| High (2,500 W) | £0.65 | £0.16 | £4.88 | £59.31 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.25 h/day ≈ 137 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 air compressor costs £0.39 per hour and about £35.59 per year at 0.25 hours a day. Each £1.00 of electricity buys roughly 2.6 hours of use.
How to lower the cost of running a air compressor
- Fix air leaks. A hissing fitting can run the compressor for hours a day.
- Drain the tank regularly so it holds its rated volume.
- Switch it off when leaving the workshop.
