Typical rating and how we worked this out
This page uses a typical rating of 1.2kW for a electric lawnmower; published figures for this appliance range from 1kW to 1.6kW. A corded electric lawnmower typically draws 1,000–1,600W; because most gardens only need mowing once a week through the growing season, the annual running cost is small even at that wattage. The running cost follows the same formula used across this site: watts ÷ 1,000 × hours × unit rate. Typical use is modelled as 1 mow a week through the growing season, which is how the per-day, per-week and per-year figures above were calculated — see the cost-to-run calculator to change the wattage, hours or region yourself.
Rate used: Ofgem price cap, 1 October to 31 December 2026, GB average electricity — 26.32p/kWh (excl. VAT, removed 1 Oct 2026–31 Mar 2027).

Three practical ways to cut the cost

- Mow more often when grass is growing fast rather than letting it get long, which takes more power in one pass
- Choose the correct cutting height for the season
