Best Cordless & Battery Lawn Mowers UK 2026
Cordless has quietly become the default mower for British gardens. For anything under about 600 m², a good battery mower now out-cuts a cheap petrol one: quieter, lighter, push-button start, no fuel or servicing. Below are the nine cordless and battery lawn mowers we rate most highly for 2026, compared on the specs that actually matter - voltage, cutting width, battery, runtime, weight and price - and ranked by who each one is for.

How we chose these mowers
We don't run a test lab and we don't pretend to. Our recommendations are built from published manufacturer specifications, verified owner reviews on Amazon UK and retailer sites, and UK pricing data, cross-checked so the numbers on this page match the numbers you'll find on the box. Where a figure is the maker's claim rather than an independent measurement, we say so.
Rankings are based on cut quality, battery and runtime for the garden size in question, weight, build, and value at UK prices. We update picks when models are discontinued or superseded. We earn affiliate commission on some links, but it never decides the order of a list. More on our method.

EGO Power+ LM2122E-SP
EGO
The closest a cordless mower gets to the feel of a petrol self-propelled. The 56 V motor powers through long, damp grass that smaller batteries stall on, and the variable-speed drive makes a 600 m² lawn easy work. If your garden is over 400 m² and you want to ditch petrol, this is the one to beat.
Pros
- + 56 V delivers genuinely petrol-like power
- + Variable-speed self-propelled drive
- + IPX4 weather-resistant; folds flat for storage
Cons
- − Expensive
- − Soft stripes vs a rear-roller mower
Bosch UniversalRotak 36-550
Bosch
If you already own Bosch garden kit, the shared 36 V Power for All battery makes the UniversalRotak the obvious pick - one battery runs the hedge trimmer, blower and strimmer too. The 50 L box and 40 cm deck are class-leading under £350.
Pros
- + Quiet ProSilence motor
- + 36 V Power for All battery shared across Bosch garden tools
- + 50 L grass box is huge for the class
Cons
- − Plastic deck flexes on rough ground
- − Heavier than a compact 18 V mower
Gtech CLM 2.0
Gtech
The cordless we recommend most to first-time buyers. It cuts cleanly, the wide 42 cm deck clears a 400 m² lawn on a charge, and the 50 L box means less stopping to empty. Note it uses a rear comb rather than a roller, so it will not leave defined stripes.
Pros
- + Light enough to carry one-handed
- + Huge 50 L grass box for the class
- + Simple, foolproof to live with
Cons
- − No rear roller, so no defined stripes
- − No mulching plug in the box
Makita DLM382 (2× 18V LXT)
Makita
For the huge number of UK households with Makita LXT drills and drivers, the DLM382 is the cheapest route to a serious 38 cm cordless - buy bare and add the batteries you own. Brushless, well built, and quietly one of the best-value picks if the ecosystem fits.
Pros
- + Runs on two standard 18 V LXT packs you may already own
- + Brushless motor, trade-grade build
- + Twin-port keeps cutting when one pack drains
Cons
- − Bare tool only at the best prices
- − No self-propelled option
Ryobi RY18LMX40A-150
Ryobi
If you already own a Ryobi drill or strimmer, the RY18LMX40A is the cheapest sensible cordless going - buy bare-tool and you are under £160 for a real 40 cm self-propelled deck. Not the most powerful here, but on a dry, regularly mown lawn it is more than enough.
Pros
- + Slots into the 18 V ONE+ ecosystem (200+ tools)
- + Self-propelled drive on this model
- + Brushless motor for a long life
Cons
- − Single 18 V pack works hard on damp grass
- − Cut-height lever is fiddly
Mountfield Princess 34 Li-48
Mountfield
A proper Italian-built striping mower for a fraction of a petrol Princess. If you care about stripes more than acreage, this is the cheapest way to get them from a battery mower with a metal deck.
Pros
- + Steel deck feels solid
- + True rear roller for sharp stripes
- + 48 V system with decent torque
Cons
- − Only a 34 cm cut
- − Battery sold separately at some retailers
Greenworks G40LM41
Greenworks
A lot of deck and grass box for around £300. If you have a 400-500 m² lawn and do not want to spend EGO money, the Greenworks 40 V (G40LM41) ships with two batteries and covers a lot of grass per session. The current UK model that replaced the older 45 cm version.
Pros
- + Big 41 cm deck and 50 L box for the money
- + 40 V platform shared across Greenworks garden range
- + 2-in-1 mulch or collect, twin batteries included
Cons
- − Build is functional rather than premium
- − Heavier to manoeuvre in tight spots
WORX WG730E (2× 20V PowerShare)
WORX
A lot of cordless for the money - twin 20 V packs in the box means no second purchase to get going. Best for a tidy 200-300 m² lawn where value matters more than a wide deck or stripes.
Pros
- + Two batteries included at a low price
- + PowerShare packs run other WORX tools
- + Intellicut dial trades power for runtime
Cons
- − 34 cm deck is modest for the weight
- − No self-propelled drive
Bosch CityMower 18V-32-300
Bosch
The best small-garden battery mower under £200. Light, quiet, simple, and it shares the 18 V Power for All pack with Bosch drills and trimmers. For a courtyard or front lawn, you do not need more.
Pros
- + Very light - easy to lift and store
- + Shares the 18 V Power for All battery
- + Cheapest way into a quality brand platform
Cons
- − 32 cm deck is small for over 200 m²
- − Modest 31 L grass box
How to choose: the five specs that matter
1. Match cutting width to your lawn
The cutting width is how wide a strip the blade clears per pass - wider finishes faster but is heavier to steer. Rough guide: 30-34 cm for gardens under 150 m², 36-40 cm for a typical 150-400 m² semi, 41-46 cm for 400-800 m², and 48 cm+ (usually twin-battery, self-propelled) for the largest lawns.
A wider deck clears more grass per pass but is heavier to steer in tight spots.
2. Voltage drives torque
The bigger the battery number - 18 V, 36 V, 40 V, 56 V - the more torque the motor delivers, and torque is what stops a mower stalling in long, damp grass. A weekly-mown front lawn is happy on 18 V; a back lawn that goes feral over a holiday wants 36 V or more. Our buying guide explains voltage, runtime and brushless motors in full.
Higher voltage means more torque, so the blade keeps cutting in long, damp grass.
3. Battery: single, twin, and brushless
Single-battery mowers are lighter and cheaper; twin-battery models double the runtime for roughly £100 more and suit lawns over 500 m². Almost every mower here uses a brushless motor - quieter, more efficient and longer-lived than the brushed motors in cheap supermarket mowers. Crucially, the battery is a platform decision: a Bosch, Ryobi or Makita pack also runs that brand's hedge trimmer, blower and strimmer.
4. Self-propelled or push?
Self-propelled mowers drive their own wheels so you steer rather than shove - worth the £80-£150 premium on a slope, on lawns over 400 m², or if a 20 kg push is uncomfortable. For a flat lawn under 200 m², a push mower is lighter, cheaper and simpler.
5. Weight and stripes
Manufacturer weights often omit the battery; budget 1-2 kg more than the spec sheet, and knock 5 kg off your limit if you lift the mower over a step each week. For the classic striped finish you need a rear-roller mower - wheeled mowers leave no stripe.

What owners actually say about our top picks
Recurring feedback drawn from real owner reviews and forums. Attributed to source, not our own testing.
EGO Power+ LM2122E-SP
Owners rate it the closest cordless to petrol: the wide 52 cm deck and 56 V motor power through long grass, with a charge lasting close to the claimed runtime. The recurring gripe is ergonomics, not cutting.
- LIKED
"Ploughs into overgrown grass without slowing; the motor ramps up power to cope rather than stalling." Trusted Reviews
- LIKED
"Big wheels make straight lines and stripes easy, and one charge gives close to 50 minutes of real mowing." Trusted Reviews
- GRIPE
"The grass bag sticks out so you can kick it on every step at higher drive speeds, and there is no bag-full indicator." Trusted Reviews
- GRIPE
"The variable drive-speed controller is finicky to set to a comfortable pace." Lawn Care Forum
Bosch UniversalRotak 36-550
Owners rate it well overall (around 3.9 / 5 across UK reviews) for its genuinely quiet ProSilence motor and ~50 minute runtime. The common niggles are a fiddly grass box and casing, not the cut.
- LIKED
"The ProSilence motor is noticeably quieter than rivals, and one charge covers a lawn up to about 550 m²." Which?
- LIKED
"One-touch height adjustment and the LeafCollect blade make it easy to live with day to day." EasyLawnMowing
- GRIPE
"The grass box can be tricky to empty and the plastic casing is stiff to open." Which? owner reviews
- GRIPE
"A single 4.0 Ah battery is more than a small garden needs; it suits medium lawns better." Owner reviews
Gtech CLM 2.0
Owners love the 50 L box and how simple it is to live with, but two complaints recur: it can cut out on the lowest height settings, and real runtime falls well short of the claim on long or damp grass.
- LIKED
"The 50 L grass box is far bigger than most cordless rivals, so far less stopping to empty it." EasyLawnMowing
- LIKED
"Hard to fault for the price; build quality and reliability hold up well." Ideal Home
- GRIPE
"It keeps cutting out on the lowest cutting height when the ground is uneven and the blade catches." Owner reviews, EasyLawnMowing
- GRIPE
"Real runtime is closer to 20 minutes than the headline figure once the grass is long or wet." Owner reviews, EasyLawnMowing
Makita DLM382
Owners rate it highly on Amazon for being quiet, light and sturdily built, with the twin-battery setup giving a long cut. The limits are large or steep lawns and long wet grass.
- LIKED
"Quiet, lightweight and cuts even high grass with ease, then drops low for a clean finish." Amazon UK owner reviews
- LIKED
"Twin 18 V LXT batteries mean it cuts for ages, and the build is sturdy as you expect from Makita." eBay owner reviews
- LIKED
"The 40 L box has a fill-level indicator and pops off easily to empty." Which?
- GRIPE
"It can struggle on long grass, especially when wet, and is not the one for very large or steep lawns." Which? owner reviews
- GRIPE
"No self-propelled option, and buying the kit with batteries rather than body-only pushes the price up." Amazon UK owner reviews
Ryobi 18V ONE+ mower
Owners praise how light it is and the value of the ONE+ ecosystem, but the single complaint dominates every review: battery life. A second pack quickly goes from nice-to-have to essential.
- LIKED
"Ultra-light, easy to store, and the mulching function works well for a small lawn." DIY Garden
- LIKED
"Slots into the 18 V ONE+ system, so the battery runs your other Ryobi tools too." The Review Guy
- GRIPE
"A genuine 5.0 Ah pack gives roughly 15 to 20 minutes, best kept to lawns under about 150 m²." The Gadgeteer
- GRIPE
"A spare battery stops being a luxury and becomes a necessity for anything but a small garden." DIY Garden
Mountfield Princess 34 Li-48
Owners buy it for the rear roller and the classic British stripe, and on that it delivers. The honest caveat from reviewers: being lightweight, the stripes are not as deep or long-lasting as a heavy petrol mower.
- LIKED
"The integrated rear roller leaves neat classic stripes with no extra effort." Mountfield owner reviews
- LIKED
"A solid steel deck and proper roller at a fraction of a petrol Princess." EasyLawnMowing
- GRIPE
"Being lightweight, the stripes it presses in do not last as long as a heavier mower would manage." Paul's Mower Reviews
- GRIPE
"The 34 cm model ships with a single 2 Ah battery; the 38 cm version adds a second for bigger lawns." Owner reviews
