How Much Does It Cost to Run an 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. A weekly 45-minute mow works out at about 0.1 hours a day averaged over the year and costs a few kWh a month.
A typical electric lawn mower (corded or battery) (1,200 W) costs £0.32 per hour, or about £0.95 per month at 0.1 hours a day in the UK. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |

How to lower the cost of running an 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.
