Which? reveals the best new cordless grass trimmers

Which? has reviewed ten new grass trimmers, including eight cordless models from top brands including Bosch, Black & Decker, Gtech and Stihl. Some were excellent and won us over with their mix of power and precision, while others left us underwhelmed.

Cordless grass trimmers have some fundamental advantages over corded electric and petrol models. There’s no danger of cutting through an electrical cord and you won’t have to drag the cord behind you or find an extension cord to get to the end of the garden. Compared to petrol models they are a breeze to start, lighter, less noisy and vibrate less.

Be careful when looking for a bargain as some cordless garden tools are sold without a battery and charger.

Otherwise, you will have to add the cost of both the battery and the charger, making that ‘bargain’ a lot more expensive. Find out more in our guide to cordless grass trimmers.
