10 Best Cordless Electric Mowers 2025 in the UK

The Worx WG737E 40V Cordless Lawnmower is a solid choice for those with medium to large gardens ranging from 300 to 550㎡. Its 37cm cutting width is ideal for maneuvering through narrow spaces and tackling sloped areas efficiently. Powered by two 20V 4Ah batteries, it offers a good balance of runtime and power, making it possible to complete most mowing tasks without frequent recharging. These batteries are part of the Worx PowerShare system, allowing them to be swapped with other tools, adding versatility and cost-effectiveness.

At 14 kg, this mower is relatively lightweight, making it easy to handle and store. The height adjustment feature provides flexibility in mowing preferences, which can be a boon for maintaining different types of grass. The IntelliCut technology is a standout, automatically adjusting power for thicker grass, which helps maintain performance and efficiency. However, the charging time for the batteries might be a point of consideration if you have a larger area or require frequent mowing sessions.

Despite the robust motor and technology, the mower remains quiet, which is a plus for noise-sensitive areas. Additionally, the 2-in-1 bag and mulch functionality offer practical lawn care options, although some might find the 37cm cutting width a bit narrow for extremely large gardens, necessitating more passes. The WG737E is user-friendly, offering a combination of lightweight design and smart technology, making it a viable option for those seeking convenience and efficiency in a cordless lawnmower.

The Greenworks 40V Cordless Lawnmower is designed for medium-sized lawns up to around 500 square meters, which is ideal for a typical suburban yard. It comes with two 40V 2Ah lithium batteries, allowing you to cover the full lawn without having to recharge in the middle. One battery powers the mower while the other charges, providing fairly consistent runtime. The 41cm cutting width is a good size—wide enough to cut grass efficiently but still manageable for careful edging or smaller spaces.

You can adjust the cutting height in five steps, from 25mm up to 80mm, with a simple lever, letting you tailor the grass length easily. The mower offers two ways to handle clippings: you can collect them in a large 50L bag or mulch them to feed nutrients back to your lawn. This flexibility is handy depending on whether you prefer a cleaner finish or want to naturally enrich your grass.

Weighing just over 20 kilograms (about 45 lbs), it’s light enough to push without too much effort and features large rear wheels that help it roll smoothly over uneven ground. The handle folds down for compact storage, which is useful if you have limited space. The battery capacity of 2Ah per battery is modest compared to some other models, so while it handles lawns up to 500m², it might struggle with larger areas or very thick grass. Although the mower is plastic-built, which helps keep weight down, it may not feel as robust as metal alternatives over many years of heavy use. Greenworks backs it with a 3-year guarantee and a 2-year battery warranty, reflecting confidence in its durability. For those seeking a quiet, eco-friendly alternative to petrol mowers for a medium lawn with easy handling and decent cutting options, this mower offers good value with two batteries included and the convenience of cordless operation.

The Greenworks 48V Self-Propelled Cordless Lawnmower is designed for those with large lawns up to 480 square meters. It features a generous 46cm cutting width, which means fewer passes to cover your lawn, saving both time and effort. Powered by two 24V 4Ah batteries, this mower promises a robust and efficient mowing experience without the noise and emissions associated with petrol mowers. The inclusion of a twin charger helps minimize downtime by charging both batteries simultaneously.

One standout feature is its self-propelled mechanism, which significantly reduces the physical effort needed, particularly beneficial for larger lawns or users who might find pushing a heavy mower challenging. The 27.5 kg weight is on the heavier side for a cordless mower, but the self-propulsion compensates for this during operation.

The mower boasts versatility with its 3-in-1 functionality—mulching, side discharge, and collection in a 55L grass bag. Users can adjust the cutting height across seven positions from 25mm to 80mm, catering to different grass lengths and personal lawn aesthetics. However, the mower's size and weight may pose storage challenges in smaller spaces, even with the foldable handlebar design. Additionally, while the battery system allows for good coverage without needing a recharge, charging the batteries fully takes some time, which might be a downside if you have larger areas to cover in multiple sessions.

The product comes with a reassuring three-year guarantee and a two-year warranty on the batteries, underlining Greenworks' confidence in its durability and performance. This mower will appeal to environmentally conscious users searching for a powerful, petrol-free solution for maintaining large lawns with convenience and ease.
