Best Cordless Lawn Mowers UK 2026: Six Picks Compared
Cordless has quietly taken over the British lawn. A battery mower starts on a button in any weather, makes a fraction of the noise of a petrol machine, needs none of the fuel, oil, filters or winter servicing, and has no cable to slice through or trail around trees. For the average UK garden the only real question left is which one, and the honest answer depends far more on the size of your lawn and the battery platform you want to live with than on any single headline number.
This guide explains the three things that decide whether a cordless mower suits your garden, then compares six mowers genuinely sold on Amazon UK right now, from compact machines for small courtyard lawns up to self propelled mowers that will handle a big family garden on one charge. No invented run times, no fake tests, just the trade offs laid out plainly.
The Three Things That Actually Matter
Ignore the marketing and match these three things to your actual garden.
- Cutting width against lawn size. This is the master decision. A narrow 32 to 34cm deck is nimble and light for a small lawn but tedious on a big one; a 37 to 43cm deck clears a large garden in far fewer passes but is heavier and needs more battery. As a rough guide, up to around 200 square metres suits a 32 to 37cm mower, 200 to 400 square metres suits a 37 to 40cm mower, and beyond that you want a wide deck and ideally self propulsion. Buying too small for your lawn is the most common regret.
- Battery platform and run time. The battery is the expensive part and it usually fits the maker's other garden and power tools, so choosing a mower means choosing a platform. Run time depends on battery size in amp hours and how thick your grass is, and makers quote best case figures on short dry grass, so plan for less. For medium and large lawns look for a mower that takes two batteries, either for double the run time or so you can charge one while using the other and never stop mid cut.
- Brushless motor and cutting features. A brushless motor runs cooler, pulls more work from each charge and lasts longer, and is worth seeking out above the budget tier. Beyond that, look for a large easy to empty grass box, a wide range of cutting heights set by a single lever, and a rear roller if you want the striped finish a roller leaves on a formal lawn. Mulching, where the clippings are chopped fine and dropped back to feed the lawn, saves emptying the box and is a genuinely useful option to have.

Our Six Picks for 2026
Bosch CityMower 18 Cordless Lawn Mower
Best for small lawns and Bosch owners
Bosch's green Power for All 18V system is one of the most widespread home battery platforms in Britain, sitting behind everything from drills to hedge trimmers, and the CityMower 18 is its neat small lawn mower. With a roughly 34cm deck it is light, quiet and easy to steer around beds and paths, and if you already own Bosch Power for All batteries the bare cost is very reasonable. Considerations: it is designed for small to medium lawns and will feel slow on anything large, the single battery run time suits a courtyard or modest back garden rather than a paddock, and the grass box is compact so you empty it more often. For a tidy urban lawn, especially in a Bosch household, it is the sensible, quiet choice. Typical band is around £130 to £190.
View on Amazon UKGreenworks 48V Cordless Lawn Mower
Best value for a mid size lawn
Greenworks has made its name giving keen gardeners a lot of cordless capability for sensible money, and its 48V mowers (run by two 24V batteries) are the value benchmark for a mid size British lawn. A deck around 41cm clears a family garden in far fewer passes than the small machines, the twin battery setup gives useful run time and lets you charge one while cutting with the other, and the wider Greenworks range means the batteries earn their keep across other garden tools. Considerations: it is a bigger, heavier machine than the compact mowers, storage takes more room, and the platform, while good value, is less universal than Bosch or Makita in a typical shed. For most ordinary UK lawns it is the smart money. Typical band is around £180 to £280.
View on Amazon UKEGO Power+ LM2130E Cordless Lawn Mower
Best for power and big lawn range
EGO's 56V platform is the closest a cordless mower gets to petrol performance, and the LM2130E is its popular self propelled machine for larger gardens. The wide deck around 52cm eats up a big lawn, the self propulsion saves your back on slopes and long runs, and EGO's arc lithium batteries are among the best in the business for both power and longevity. It folds compactly for storage, which large mowers often do not. Considerations: it is the most expensive option here, it is a substantial machine that needs the space to match, and a single large battery on very long grass will still need a spare for the biggest gardens. For someone with a genuinely large lawn who wants to leave petrol behind without losing capability, it is the standout. Typical band is around £350 to £550.
View on Amazon UKFlymo EasiStore 340R Cordless Lawn Mower
Best for small lawns and easy storage
Flymo is the name most British gardeners grew up with, and the EasiStore 340R is built around a problem the others ignore: where do you put the thing. It folds compactly and hangs flat on a wall or garage hook, which in a small shed or a flat with limited storage genuinely matters. The roughly 34cm deck and rear roller suit a small to medium lawn and leave a tidy striped finish, and the controls are refreshingly simple for anyone who just wants to cut the grass and put it away. Considerations: the battery and deck size suit smaller gardens, run time is modest, and the Flymo battery platform is narrower than the big tool ecosystems if you want to share batteries around. As an uncomplicated mower for a small British garden, it is a friendly, familiar choice. Typical band is around £150 to £220.
View on Amazon UKMakita DLM382 Cordless Lawn Mower
Best for Makita LXT owners with a mid size lawn
Makita's LXT 18V system is the most widespread trade battery platform in the country and increasingly common in home sheds too, and the DLM382 lets those batteries mow the lawn. Running on two 18V batteries for 36V of power, with a deck around 38cm, it is a well built, reliable mid size mower with Makita's usual solid engineering, and if you already own LXT tools the batteries you have for the drill and strimmer run the mower too. Considerations: it is priced as a quality machine rather than a bargain, you need a pair of decent capacity LXT batteries to get sensible run time, and the deck size suits medium rather than very large lawns. For an LXT household that values build quality and one battery system across the whole garden, it is the natural pick. Typical band is around £250 to £380.
View on Amazon UKWORX WG779E Cordless Lawn Mower
Best value for a small to mid lawn
WORX built its reputation on clever, keenly priced cordless kit, and the WG779E is one of the most bought budget mowers in the UK for a straightforward reason: it comes as a complete package with batteries and charger for less than many rivals cost bare. The roughly 34cm deck, single lever height adjustment and included batteries make it an easy, complete first cordless mower for a small to medium lawn, and the WORX PowerShare battery fits a wide range of other affordable WORX garden tools. Considerations: it is built to a price, so the deck and construction are lighter duty than the premium machines, run time suits smaller lawns, and it is happier on a regularly cut lawn than on long neglected grass. As a complete, ready to mow package that removes the battery guesswork, it is excellent value. Typical band is around £150 to £220.
View on Amazon UKWhich One Should You Buy?
Small lawn? The Flymo EasiStore and WORX WG779E are the easy answers: light, keenly priced and simple to store. The Bosch CityMower joins them if you are already on Bosch Power for All.
Average family lawn? The Greenworks 48V is the value pick with its wider deck and twin battery run time, and the Makita DLM382 is the one to buy if your shed already runs on LXT.
Large lawn or slopes? The self propelled EGO Power+ LM2130E is the machine that genuinely replaces a petrol mower, with the deck width and battery power to match a big garden.
Frequently Asked Questions
Is a cordless mower powerful enough, or do I still need petrol?
For the vast majority of UK gardens, cordless is now more than enough. Modern brushless motors and 36 to 56 volt batteries cut ordinary lawn grass easily, and only change the game on very large areas or rough, long, damp grass cut infrequently, where a big self propelled cordless like the EGO, or occasionally still a petrol machine, earns its place. For a normal weekly cut, petrol's noise, fumes and servicing are a cost with little benefit left.
How big a lawn can one battery charge handle?
It depends on battery size and grass condition, and makers quote best case figures, so plan conservatively. As a rough guide a single mid size battery suits small to medium lawns, while medium to large lawns are far more relaxing with a two battery mower so you can swap or run both. If your lawn is near the top of a mower's stated range, buy a spare battery from the start rather than stopping halfway through the cut.
What cutting width should I choose?
Match it to lawn size. Up to roughly 200 square metres, a 32 to 37cm deck is nimble and light. From 200 to 400 square metres, a 37 to 40cm deck saves passes. Beyond that, choose a wide deck of 40cm or more and ideally self propulsion. Going too narrow for a big lawn turns mowing into a chore; going too wide for a tiny lawn just makes the mower heavier to handle around beds.
Should I mulch or collect the clippings?
Both have their place. Collecting keeps the lawn tidy and is best for the first cuts of spring and any long grass. Mulching chops the clippings finely and drops them back to feed the lawn with nitrogen, which saves emptying the box and helps the grass in dry spells, and works best when you cut little and often so the clippings are short. Many mowers here offer both, which gives you the choice through the season.
How do I care for the battery so it lasts?
Lithium batteries last longest stored around half charged in a cool, dry place, not left flat or fully charged for months, and never left in a freezing shed all winter or a baking greenhouse in summer. Charge after use rather than leaving the pack empty, bring it indoors over winter, and avoid completely draining it every time. Treated this way a good battery commonly lasts several years and often outlives cheaper mowers entirely.
