The best cordless lawn mowers for UK gardens

Last updated: · By the Hearth & Lawn team

How we chose these: We haven't tested these mowers ourselves. Our picks are based on manufacturer specifications, UK retailer prices, independent tests (mainly BBC Gardeners' World Magazine) and patterns in owner reviews. Where sources disagree, we say so. Prices were checked on 17 October 2026 and move a lot between autumn and spring.

Cordless mowers have taken over from corded electric mowers for most gardens, and now challenge petrol on medium-sized lawns too. You get no cable to trip over or cut through, no petrol to store over winter, and much less noise.

The decision that matters more than which model is which battery system you buy into. The battery and charger are a big part of the price, and once you own them you can buy hedge trimmers, blowers and strimmers from the same range as cheaper "bare tool" versions. We've organised our picks around that.

How to choose a cordless lawn mower

1. Start with your lawn size

Makers quote a "mows up to" figure per charge. Treat it as a best case: long, wet or thick grass and slopes all cut it. Roughly:

  • Under 150m² (a typical terrace or small semi garden): a 32–34cm mower with one 18–24V battery is plenty.
  • 150–400m²: look at 36–42cm, a bigger battery (4–5Ah) or two batteries, or a spare battery.
  • 400m² and over: 46cm-plus, ideally self-propelled, running on two batteries or a high-voltage system.

Not sure of your lawn size? Measure it with the distance tool in Google Maps or Apple Maps, or pace out length × width.

2. Choose a battery platform you'll stick with

The battery and charger can easily be a third or more of a kit's price. If you already own cordless tools from one of these ranges, buying the mower as a "bare tool" can save a lot. If you don't, think about which hedge trimmer, strimmer or leaf blower you might want later.

Platform Used by Why it matters
Ryobi 18V ONE+ Ryobi Ryobi says the system covers 200+ tools across garden, DIY and home
POWER FOR ALL ALLIANCE (18V) Husqvarna Aspire, Bosch, Flymo, Gardena and others One battery works across brands. Husqvarna says 10+ brands and 100+ devices.
Worx PowerShare (20V) Worx Two 20V batteries combine for 40V tools like the Nitro mower. The same batteries run the Landroid Vision Cloud robot mower.
EGO 56V EGO High-voltage system aimed at bigger garden jobs
Greenworks 24V Greenworks Budget-friendly, with a growing garden range

3. Push or self-propelled?

Self-propelled models drive the wheels for you. That matters on slopes and on lawns over about 300m², and less on a flat small lawn. The trade-offs are weight (the Worx Nitro is 28.7kg, the EGO 24kg) and shorter battery runtime when the drive is on.

4. Cutting height range

A wide range of heights helps you raise the cut in dry summers and bring an overgrown spring lawn back down gradually. A common rule is to take off no more than a third of the grass height at a time. Single-lever adjustment is much easier than moving each wheel.

5. Storage

If the mower lives in a cramped shed or under the stairs, look for:

  • a handle that folds completely flat
  • a mower that stands upright on its end. The Husqvarna Aspire also comes with a wall hook.
  • a fabric grass bag that collapses, rather than a rigid box

6. Mulching

Most mowers here come with a mulching plug. It chops clippings finely and drops them back on the lawn, so you have nothing to empty. Mulching works best when you mow little and often.

7. Noise

Cordless mowers are far quieter than petrol, but not silent. As an example, Husqvarna quotes 74 dB(A) at the operator's ear for the Aspire LC34-P4A, with a measured sound power of 86 dB(A). Most cordless mowers are in a similar range. Compare like with like, as makers quote different measures.

Running costs: what does a charge cost?

Very little. A battery's energy content is roughly its voltage × its amp-hours. At the Ofgem price cap of 26.32p per kWh (average direct debit electricity, 1 October to 31 December 2026), one full charge costs roughly:

Battery Approx. energy Approx. cost per full charge
Husqvarna P4A 18V 4Ah (72Wh, maker's figure) 0.072kWh ~1.9p
Ryobi 18V 5Ah ~0.09kWh ~2.4p
Greenworks 24V 4Ah ~0.096kWh ~2.5p
Worx 2 × 20V-max 4Ah (18V nominal) ~0.144kWh ~3.8p
EGO 56V 4Ah ~0.224kWh ~5.9p

These are our estimates: nominal voltage × capacity × 26.32p, ignoring charger losses of perhaps 10–20%. Even with losses, a season of weekly mowing costs well under £5 in electricity.

The bigger long-term costs are replacement batteries (lithium-ion packs gradually lose capacity) and the occasional new blade. If the mower is likely to outlast its first battery, choosing a popular platform makes replacements easier to find.

The best cordless lawn mowers in detail

1. Greenworks GD24LM33: best budget mower for small lawns

Price checked: the kit with a 4Ah battery and charger (GD24LM33K4) is listed at about £179.98–£189.99 at UK mower specialists. Greenworks UK lists the tool-only version at £124.99 but showed it as unavailable when we checked.

Key specs (manufacturer):

  • 33cm cut; 25–70mm in five heights
  • 30L bag plus mulching
  • Brushless motor; 9.5kg (without battery)
  • Up to 250m² on a 2Ah battery, or 280m² on a 4Ah
  • 3-year mower and 2-year battery warranty

For a small, flat lawn this covers the basics for less money than the big names. The brushless motor is efficient, the handle folds for storage, and the battery fits Greenworks' other 24V garden tools.

Gardeners' World rated it 4.5/5 as their best budget cordless mower for small gardens. Their tester found it easy to put together and comfortable to push, but the handle felt short for taller users and it struggled with long grass.

Pros

  • Low price for a brushless mower
  • Collects or mulches
  • Light and easy to manoeuvre
  • Generous coverage for its size

Cons

  • Not for long or neglected grass
  • Handle may be short for tall users
  • Greenworks' 24V range is smaller than Ryobi's or POWER FOR ALL

2. Ryobi RLM18X33B50C: best small-lawn mower if you want one battery for everything

Price checked: £219.99 at Ryobi UK.

Key specs (manufacturer):

  • 33cm cut; 25–65mm in five positions, single-point adjustment
  • 35L bag plus mulch plug; EasyEdge grass combs for cutting closer to walls and fences
  • 18V ONE+ 5.0Ah battery and charger included
  • Up to 150m² per charge
  • 3-year guarantee

Ryobi's ONE+ range is huge: Ryobi says more than 200 tools. That makes this a sensible starter kit if you also want a drill, strimmer or hedge trimmer on the same battery.

Gardeners' World rated it 4.8/5 and found it very light at about 8.5kg with the battery, so you can mow one-handed. Their only real complaint was that the height adjuster was fiddly.

Pros

  • Very light
  • Big 5Ah battery included
  • Huge tool range on the same battery
  • Edge combs help along walls

Cons

  • Ryobi's own figure is 150m² per charge, so it's for small lawns only (Gardeners' World quoted 225m²; we've used the maker's lower figure)
  • Height adjustment is a bit fiddly
  • Push-only

3. Husqvarna Aspire LC34-P4A: best for small sheds and flats with gardens

Price checked: £359 at Husqvarna UK (kit with battery and charger). Independent dealers listed it from about £287 to £299.

Key specs (manufacturer):

  • 34cm cut; 30–65mm in four steps
  • 30L bag plus BioClip mulching plug
  • 18V 4Ah (72Wh) POWER FOR ALL ALLIANCE battery; 11.8kg
  • Telescopic handle; stands upright or hangs on the included wall hook
  • Automatic power boost in thick grass; battery level display

This mower is built around storage. It folds flat, stands upright or hangs on a wall, and has lifting handles front and back for carrying it up steps or through the house to a back garden. The battery is part of the POWER FOR ALL ALLIANCE, so it also works in many Bosch, Flymo and Gardena tools. That's a real advantage if you already own any of them.

Gardeners' World gave it 4.9/5, the highest score in their cordless test. They praised its quietness and how it handled long grass.

Pros

  • Very compact storage
  • Quiet
  • Cross-brand battery
  • Power boost in tough grass
  • Battery level visible as you mow

Cons

  • Only four cutting heights
  • Husqvarna's own price is higher than dealers'
  • Gardeners' World quoted a 95-minute charge and 500m² coverage, but Husqvarna's spec page doesn't state a coverage figure, so treat that as indicative
  • Gardeners' World lists a 2-year warranty, shorter than some rivals

4. Worx Nitro WG749E: best self-propelled mower for medium to large lawns

Price checked: £359.99 at Worx UK (RRP £449.99).

Key specs (manufacturer):

  • 46cm cut; 20–80mm in seven positions, single lever
  • 55L bag plus mulching insert
  • 2 × 20V 4.0Ah PowerShare batteries (40V) and dual charger; about a 2-hour charge
  • Self-propelled up to 5.2km/h
  • Mows up to 800m² per charge; 28.7kg
  • 5-year tool warranty if registered within 30 days; 2 years on batteries

If you're replacing a petrol mower on a bigger lawn, this is strong value at its current price. You get a wide 46cm deck, variable-speed drive and Worx's "IntelliCut" system, which raises torque in thick grass. The two batteries also run Worx's other 20V and 40V tools, and the Landroid Vision robot mower.

Gardeners' World rated it 4.8/5. They liked the visible battery gauge and the stand-up storage, but found the collection bag fiddly to assemble.

Pros

  • Wide cut
  • Big coverage
  • Self-propelled
  • Long warranty if registered
  • Batteries shared across Worx's range
  • Stands on its end to save space

Cons

  • Heavy at 28.7kg
  • The bag is fiddly to put together
  • Overkill for small lawns

5. EGO LM1702E-SP: best premium mower for sloping lawns

Price checked: RRP £619 at EGO. UK stockists listed it at about £525–£559.

Key specs (manufacturer):

  • 42cm cut; seven heights
  • 55L bag; mulch, collect or rear discharge
  • 56V system with a 4.0Ah battery and standard charger; about 30 minutes' runtime, up to 300m² per charge
  • Self-propelled; LED headlights; 24kg
  • Quick-release telescopic handle folds flat

EGO's 56V system is aimed at people who want something close to petrol power without the petrol. The self-propelled drive takes the effort out of sloping or bumpy lawns, and the three ways of dealing with clippings (collect, mulch or rear discharge) help with long grass after a holiday.

Gardeners' World rated it 4.5/5 for ease of use. Note that they listed it as having no mulching option, while EGO's own page lists mulching. We've used the manufacturer's information.

Pros

  • Strong 56V system
  • Self-propelled
  • Three ways to handle clippings
  • Folds flat and stands upright
  • Gardeners' World reports a 5-year tool and 3-year battery warranty

Cons

  • Expensive
  • 30 minutes on the included battery isn't much for its price; serious users will want a bigger or second battery
  • Cutting height range is unclear: EGO's spec table says 20–80mm, but elsewhere on the same page it says 25–90mm. Check before you buy if this matters to you.

Also worth considering

  • Stihl RMA 235 (bare tool, RRP £184). Gardeners' World rated it 4.5/5 for its quality of cut. It only makes sense if you already own Stihl AK batteries: they estimated a battery and charger at just under £360 extra.
  • Einhell RASARRO 36/34 (RRP £283.95). A 4.8/5 Gardeners' World pick that comes with two 18V batteries working as 36V. It's a good alternative to the Ryobi if you're already on Einhell's Power X-Change system.

FAQs

Are cordless mowers as good as petrol? For most UK domestic lawns, yes. On lawns up to about 800m², a 40V-plus self-propelled cordless mower matches petrol for everyday mowing. Petrol still makes sense for very large plots or rough grass, but you trade that for noise, servicing and storing fuel.

How long do cordless mower batteries last? Gardeners' World estimates three to five years, or about 500 charges, before a lithium-ion battery needs replacing. Storing batteries indoors over winter, part-charged and away from frost, helps.

Should I buy a kit or a bare tool? Buy a kit if this is your first tool on that battery system. Buy the bare tool if you already have compatible batteries and a charger. It's usually much cheaper.

Can I leave the battery in the shed over winter? It's better not to. Most makers advise storing lithium-ion batteries somewhere cool, dry and frost-free, part-charged rather than full or flat. Check your manual.

Cordless or robot? If you'd rather never mow again, see our robot lawn mower guide. A robot costs more upfront and still needs edges trimming, but it does the weekly work for you.

Is a cordless mower good for a small garden? Yes. That's where they're strongest. A light 33–34cm mower like the Ryobi or Greenworks is easy to carry, quick to store, and doesn't need a socket nearby.
