How Much Does It Cost to Run a Electric Lawn Mower (Corded or Battery) in the UK? (2026)
A corded mower draws 1,000 to 1,800 watts while cutting. Battery mowers use a similar amount per mow after charging losses. Weekly mowing of a typical lawn costs a few kWh a month.
A typical electric lawn mower (corded or battery) (1,200 W) costs £0.31 per hour, or about £7.02 per month at 0.75 hours a day in United Kingdom. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (800 W) | £0.21 | £0.16 | £4.68 | £56.94 |
| Typical (1,200 W) | £0.31 | £0.23 | £7.02 | £85.41 |
| High (1,800 W) | £0.47 | £0.35 | £10.53 | £128.12 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.75 h/day ≈ 328 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 electric lawn mower (corded or battery) costs £0.31 per hour and about £85.41 per year at 0.75 hours a day. Each £1.00 of electricity buys roughly 3.2 hours of use.
How to lower the cost of running a electric lawn mower (corded or battery)
- Keep the blade sharp. A dull blade makes the motor draw more and cuts worse.
- Mow when the grass is dry. Wet grass loads the motor.
- Raise the cutting height in summer to mow less often.
