Best Cordless Electric Lawnmowers UK 2023 🔋 Top Picks

Do you need a reliable cordless lawn mower? If so, then check out our top picks for the best cordless lawn mowers which are available in the UK at present. Cordless lawn mowers have long been the favourite of many gardeners, and with many models cutting-edge lithium ion technology, you can now own a battery-powered mower that’s compact, powerful and incredibly easy to manoeuvre. Go anywhere and reach anywhere in your garden with the help of a cordless lawn mower. From cutting grass on hills to manoeuvring down slopes, a battery lawn mower allows you to reach all areas of the garden without the restriction of a power cable.

Due to their lightweight and easy to carry design, you can carry them to even the most difficult places to mow the lawn. You’ll never have the inconvenience of buying, storing and adding petrol to your mower ever again when you buy a battery lawn mower. You’ll get all the benefits of a petrol machine but without all the fuss or hassle of handling fuel. Battery powered lawn mowers aren't just easy to use though - they’re also better for the environment as they’re quieter and produce no direct fuel emissions.

Don't be fooled by their size - battery lawn mowers are powerful machines that really pack a punch! Making mowing the lawn effortless from start to finish, they can cut up to 250m2 (the size of the average tennis court) with one full charge. They come with all the benefits of a cordless lawn mower too but without the hassle of handling and storing petrol.

Buying Tips and Safety Tips

• Electric mowers are definitely on the rise. They still can’t reach the same power levels as gas mowers for the most part. But they are very much relevant because of their eco-friendliness and low maintenance. So, the first thing you need to know is that the electric mowers – and this pertains to cordless mowers too – are a green and maintenance-free option. This is their biggest selling point
• But, what makes a cordless mower special? The answer – they don’t use a power cord. Instead, they have a rechargeable battery that allows them to run. Thus, cordless mowers are much more convenient than corded models. Corded machines rely on an outlet and an extension cord. They can be very hard to manoeuvre around the lawn with the cable trailing behind you. That is especially true if there are trees, shrubs or flower gardens to entangle the cord. Such machines also have a much shorter range due to cord length. A cordless mower can move around unimpeded.
• However, there are a couple of things that might deter some people from buying a battery-powered mower. First off, you should know that such mowers have a very limited run time. You can only use the mower as long as the battery allows it. You will need to stop and recharge the battery (or have a spare battery) to continue. This could lead to some frustration. If you don’t manage to finish the mowing in one go, you will have to stop and recharge. Or you may have to spend extra cash on another battery, if you have only one, so you can switch out the one that’s been spent. It is definitely best to have two batteries fully charged before beginning.  Fortunately, many of the mowers come with two batteries.
• Also, cordless mowers in the past were known for producing uneven results. With the older lead acid or Ni-Cad batteries, as the battery charge dropped so did the power of the motor, and the mower could not cut the grass as well. Fortunately, most all cordless mowers these days use lithium-ion batteries which allows the mower to run without a power drop until it is virtually fully discharged.
• If you’re dealing with thicker or longer grass, or wet grass, the mower will require more energy, leading to faster depletion of the battery charge.  Many electric mowers just don’t cut well in these conditions, either.  Their blades often get caught on the grass and the mowers simply stall. It is best to keep the blades very sharp, the lawn trimmed frequently and mow only when the grass is dry. There are, however, very powerful and notable mowers that can go through such grass, although such models are more expensive.
