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 Ryobi OLM1833B 18V ONE+ Cordless Lawnmower is a lightweight and maneuverable option for small to medium-sized gardens. Weighing just 7.7 kilograms, it offers ease of handling, which is especially beneficial for users who might struggle with heavier equipment. The 33cm cutting width is designed to efficiently navigate around obstacles and tight spaces, making it suitable for gardens with intricate layouts.

This model is part of the Ryobi ONE+ system, which means it operates with a single 18V battery that can also be used across other Ryobi tools, offering convenient battery interchangeability. However, the mower is sold as 'body only,' so the battery and charger need to be purchased separately if you don't already own them.

One of its appealing features is the easy edge grass comb, allowing you to mow right up to the garden's edge, reducing the need for additional trimming. The height of the grass cut can be adjusted across five levels (from 25mm to 65mm), providing flexibility based on your lawn's condition and your preference. The mower's autonomy, with a compatible 5.0 Ah battery, allows it to cover approximately 250 m² per charge, which is decent for its class but may require additional batteries for larger areas. The device also supports mulching, adding versatility by returning nutrients to your lawn.

The absence of a potentially dangerous mains cable or the need for petrol simplifies operation. In summary, the Ryobi OLM1833B is a practical choice for those seeking the convenience of a cordless mower that can handle small to mid-sized gardens efficiently. Its lightweight build and alignment with the Ryobi ONE+ ecosystem make it a flexible addition for those already invested in Ryobi tools.

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.
