How Much Does It Cost to Run a Well Pump in the UK? (2026)
A submersible well pump draws 750 to 2,200 watts and runs whenever the pressure tank drops. A typical household uses 1 to 2 hours of pump time a day, making it a noticeable but modest load.
A typical well pump (1,100 W) costs £0.29 per hour, or about £12.87 per month at 1.5 hours a day in United Kingdom. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (750 W) | £0.20 | £0.29 | £8.78 | £106.76 |
| Typical (1,100 W) | £0.29 | £0.43 | £12.87 | £156.59 |
| High (2,200 W) | £0.57 | £0.86 | £25.74 | £313.17 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 1.5 h/day ≈ 602 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 well pump costs £0.29 per hour and about £156.59 per year at 1.5 hours a day. Each £1.00 of electricity buys roughly 3.5 hours of use.
How to lower the cost of running a well pump
- Fix leaks and dripping taps. Every litre wasted is pump time.
- Check the pressure tank. A waterlogged tank makes the pump short-cycle.
- Water the garden in the morning when pressure and efficiency are best.
