10 Best Cordless String Trimmers 2025 in the UK

The Worx WG927E 40V Cordless Lawnmower and Trimmer Twin Pack is a great solution for medium-sized gardens (up to 230㎡). The kit includes a 34cm lawnmower and a 20V grass trimmer, making it versatile for both mowing and trimming tasks. The two 2.0Ah PowerShare batteries are interchangeable, which is convenient and means you only need one type of battery for both tools. This saves you money and reduces clutter.

The lawnmower features AUTO-IntelliCut technology, which adjusts the power according to the task, making it energy-efficient. Its six levels of cutting height adjustments allow you to tailor the cut to your garden's needs, and the electronically-controlled motor ensures a clean cut every time. However, at 17.6 kg, the kit is relatively heavy, which might make it less suitable for users with limited strength or mobility. The cordless design adds to the convenience but also means that you need to manage battery charging times.

The grass trimmer is ideal for hard-to-reach areas and maintaining edges, though its cutting width of 25 cm might be limited for larger areas. User-friendly features make this combo kit accessible even to beginners. Some limitations include its operation mode being manual, which may require more effort compared to self-propelled options. Despite these minor drawbacks, the Worx WG927E kit stands out for its environmental friendliness and cost-efficiency, making it a strong contender for those seeking a comprehensive garden maintenance solution.

The Bosch Cordless Grass Trimmer EasyGrassCut 18V-26 is designed for small to medium-sized gardens. Its lightweight build, weighing only 1.9 kilograms, makes it easy to handle, which is great if you're using this for extended periods. The trimmer features an 18V system; however, it’s important to note that the battery isn’t included, so you'll need to purchase that separately if you don't already own a compatible battery.

With a cutting diameter of 26 centimeters, it's suited for precision trimming in tighter spaces or smaller gardens. The automatic line feed system ensures continuous cutting without the hassle of stopping to adjust the line manually, adding convenience to your gardening tasks. Switching from trimming to edging is straightforward; a simple click and a twist allow you to make this change without bending over, which adds to user comfort.

The motor operates at a robust 9000 RPM, providing sufficient power for most light to medium trimming tasks, but it might struggle with thicker, more stubborn grass or weeds. Assembling the trimmer is not a concern, as it comes ready to use without any complex setup. Being battery-powered, it offers cord-free mobility, which is excellent for moving around the garden without being tethered to a power source. However, be mindful of the battery life depending on your garden size and the tasks you plan to undertake.

The noise level isn’t specified, but being a battery-powered model, it’s generally quieter than gas-powered alternatives, making it a more neighborhood-friendly choice. This trimmer is ideal for those who need a simple, effective tool for maintaining small to medium gardens, especially if you already have Bosch 18V batteries. If you're starting from scratch, consider the additional cost of purchasing batteries and a charger.
