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 40V Cordless Lawnmower is designed for medium-sized lawns up to 400m², boasting a 35cm cutting width and a 40L grass collection bag. This model comes equipped with two 40V 2Ah lithium batteries, which offer a comparable performance to traditional petrol mowers but with less noise and no emissions. These batteries are also compatible with other Greenworks 40V tools, providing versatility and convenience.

One of the mower's strengths is its adjustable cutting heights, ranging from 25mm to 70mm, which can be easily modified with a single lever. It also offers the flexibility to either collect grass clippings or mulch them to return nutrients to the lawn. Weighing 15 kg, the mower is fairly lightweight, and its 18cm rear wheels contribute to smooth navigation across various terrains. Additionally, the handle folds down to save space during storage, which is a practical touch for those with limited storage room.

However, the mower's 35cm cutting width means it may require more passes for larger areas, which might not be ideal for those with extensive lawns. The 2Ah batteries are adequate for the specified lawn size, but users who desire longer runtime without recharging may find this limiting. While it offers a manual operation mode, some may prefer more automated features for ease of use.

In terms of warranty, Greenworks provides a reassuring 3-year guarantee on the mower and a 2-year warranty on the batteries, which highlights confidence in their product's durability and customer service. This mower is well-suited for individuals who have medium-sized gardens and value eco-friendliness alongside performance.
