The best cordless lawn mowers for small gardens, compared.
Top pick: SEYVUM RLLM40D380-03 Best value: Litheli U20LM00-4U120-QL-UK-002 – Lowest shelf price among listings with at least 4.2 stars and 200 ratings, at about £109.99, with 4.3 from 684 reviews. Updated 22 October 2026.
A cordless lawn mower for small gardens is a battery rotary you push, so you can cut a terrace, a front lawn or a modest back garden without trailing a mains lead. You are usually replacing a petrol mower you do not want to store fuel for, or a corded mower whose cable catches on the path. Tell a sound one from a weak one by the cutting width, the battery capacity in amp-hours, and whether it boxes the clippings or mulches them on purpose. A wider deck finishes an open rectangle faster and is clumsier in a tight space. The up-to square metres on a listing is the seller's ceiling on favourable grass, not a measurement of your lawn. About 22–25 cm suits a strip or a pitch, about 32–34 cm a typical small front and back, and 37–40 cm an open lawn. Ordinary UK summer lawns sit around 13–25 mm, and these rotaries often bottom around 20–30 mm. What to check on the listing is in the [cordless lawn mower buying guide](/hub/lawn-and-garden-equipment/cordless-lawn-mower-for-small-gardens/sub/cordless-lawn-mower-for-small-gardens-buying-guide).

Question 1 of 2
How will you move it?
The SEYVUM RLLM40D380-03 is £159.98 with a 40 cm cut, also written as 16 inch, two 4.0 Ah packs, a claimed runtime of up to 45 minutes and a brushless motor claimed at 1,800 W. Across 13 reviews the line is 4.8, which looks high beside a thin sample, and the listing score stays at 62. The seller area is printed as 645 ft². Reviewers say it cuts well, including damp grass at a 1.5 inch setting, that an owner aged 80 could carry the 13 kg mower, and that the batteries covered a 20-minute mow. Only seven UK reviews are noted, mostly one line, against that listing count of 13. A 45 L bag is stated, but one UK review says you remove a pillar fitting before it collects, and the grass-box handle has to be assembled even though assembly required is listed as No. Height is 25–75 mm in six positions. No repeated mechanical failure appears in those seven UK reviews.
Pros
Cons
Best for: You want a 40 cm deck and two packs, and you treat 13 reviews as a starting note rather than a record.
Less suitable: You are choosing from star ratings alone, or you need a bag that collects without a fitting removed.
Specifications
Common questions
Does this listing say the mower is self-propelled?
No. The listing does not state a driven axle. Treat it as a push mower unless a later listing states one.
What cutting width and clippings setup does the listing give?
The listing gives a 40 cm cut, also written as 16 inch, and a 45 L bag. One review says a pillar fitting must come off before it collects.
Are the battery and charger in the box?
The listing includes two 4.0 Ah batteries and a charger. It does not state a BS 1363 plug.
The swift EB122C is a 22 cm mulch-only rotary at £134.99, listed for up to 50 m², with a 40 V 2.0 Ah pack, a fast charger and a claimed runtime of up to 35 minutes. Across 330 amazon.co.uk reviews the line is 4.5, which is why the listing score is 88 and why this row is the top pick in this set. Reviewers describe it as very light on slopes and usable with one hand, at 5.2 kg, and one review says it cut a small lawn that had been left long. Assembly is described as a few minutes, and the listing says it stands upright when the handle is pushed forward. Cutting height is only 30–50 mm in three positions, so a short summer sward sits outside that range. Mulch means there is no box to empty, which is a problem if you need the clippings taken away. One owner reported a control that broke after about 13 months of light use and called the mower fragile.
Pros
Cons
Best for: You have a lawn around the seller’s 50 m² figure, you can live with mulch, and you want the lightest full kit in this set with a large review sample.
Less suitable: You need a grass box, a cut below 30 mm, or more than about 50 m² on one charge.
Specifications
Common questions
Does this listing say the mower is self-propelled?
No. The listing does not state a driven axle. Treat it as a push mower unless a later listing states one.
What cutting width and clippings setup does the listing give?
The listing gives a 22 cm cut and mulch, with no grass box. Height is 30–50 mm in three positions.
Are the battery and charger in the box?
The listing includes a 40 V 2.0 Ah battery and a fast charger. It does not state that the charger has a BS 1363 plug.
The WORX WG737E is £229.00, the highest shelf price here, with a 37 cm cut, two 20 V 4.0 Ah PowerShare packs making 40 V, a charger, a bag and a mulch plug. Across 207 reviews the line is 4.5. The seller area is up to 550 m², and the bullets also say medium gardens, so this is a wide claim on a page about small lawns. Height is 20–70 mm in six positions, tool-free in the bullets, and the weight is 15.3 kg. Reviewers say it replaces a heavy petrol mower, cuts longer and damp grass, and that two packs leave charge in hand on modest lawns. Assembly is described as basic, the first charge is slow, and reviews treat it as more mower than a tiny lawn needs. A design niggle on the grass path is noted, the sampled UK reviews do not repeat a single breakage, and a runtime in minutes is not stated.
Pros
Cons
Best for: Your lawn is closer to the seller’s medium claim than to a 50 m² patch, and you want two packs, a bag and a mulch plug.
Less suitable: You have to lift the mower up steps, or the lawn is a small strip that a 22–25 cm deck would cover.

Does this listing say the mower is self-propelled?
No. The listing does not state a driven axle. Treat it as a push mower unless a later listing states one.
What cutting width and clippings setup does the listing give?
The listing gives a 37 cm cut, a bag and a mulch plug. The seller area is up to 550 m², and the bullets also say medium gardens.

The Bosch Rotak 18V-32, model 06008B9P70, is £181.00 with a 32 cm cut in the title, an 18 V 4.0 Ah pack and the AL 18V-44 charger on the POWER FOR ALL system. Across 54 reviews the line is 4.5. The bullets say small to medium-sized lawns and do not print a square-metre figure. The title includes a 35 L fabric bag and a mulch plug, height is 25–65 mm, and the weight is 14.3 kg. Reviewers say it is enough for a small front and back, praise the mulch plug, and like moving it without a cable. One review says the battery lasted an hour on their lawn, which is one lawn rather than a listed runtime. The battery release is stiff, one handle clamp would not tighten, and one owner disliked the lowest cut. Long thick grass, in those reviews, needs more frequent mowing or a second pack.
Pros
Cons
Best for: You already use Bosch 18 V POWER FOR ALL tools and you want a bag plus a mulch plug on a small front and back.
Less suitable: You need a printed area, a light mower, or a second pack already in the box for thick grass.

The DEKO DKPGLMB40VB2-K1BS-GGAZ-UK-S5 is £159.98 with a 38 cm cut, two 20 V 4.0 Ah packs described as making 40 V, a charger and a claimed runtime of up to 30 minutes. Across two reviews the line is 4.5, and the listing has that star line with no review text, so there is no praise or fault to quote. A 40 L rear bag is in the box list, the handle folds and assembly is required. The motor is claimed brushless at 3,300 rpm with no load. Height is 25–70 mm in the bullets and 25–75 mm in the table, both with six positions. Weight is not usable: the table says 350 g and the bullets say 12.5 kg, so this comparison leaves the weight as n/a. Two reviews and that clash are why the listing score is 55. Seller area and warranty are not stated.
Pros
Cons
Best for: You are comparing the printed kit on a 38 cm bagging mower and you accept that two ratings are not a trial.
Less suitable: You want owner reports, a weight you can lift with confidence, or a single height range.

The Einhell GE-CM 18/33 Li, model 3413260, is £149.95 with a 33 cm cut, an 18 V 4.0 Ah Power X-Change pack and a system charger, sold for up to 200 m². Across 7,288 reviews the line is 4.3, the largest sample in this set, and the listing score is 84. Reviewers say it suits a small irregular lawn better than a cable, that it feels light if you already use Power X-Change, at 11.2 kg, and that one charge is enough for a modest garden. Long grass needs another battery in those reviews, one unit stopped even though the battery tested fine, and some buyers doubt the build. The bullets say it is supplied without a collection bag and with side discharge, while an item highlight mentions a 30 L grass box, so whether a box is in this carton is unresolved. Height is 25–65 mm in five central positions. The warranty line is two years, plus one extra year on registration, as listed.
Pros
Cons
Best for: You already own Power X-Change tools, the lawn is nearer 200 m² than 50 m², and you can confirm the bag on the live page.
Less suitable: You need a grass box you can count on from the bullets, or a single charge through long grass.

Common questions
Does this listing say the mower is self-propelled?
No. The listing does not state a driven axle. Treat it as a push mower unless a later listing states one.
What cutting width and clippings setup does the listing give?
The listing gives a 33 cm cut. The bullets say it is supplied without a collection bag, while a highlight mentions a 30 L box, so the bag is not settled.
Are the battery and charger in the box?
The listing includes an 18 V 4.0 Ah Power X-Change battery and a system charger. It does not state a BS 1363 plug.
The Litheli U20LM00-4U120-QL-UK-002 is £109.99 with a 33 cm cut, a stated 20 V 5.0 Ah pack and up to 30 minutes in both the bullets and the table. Across 684 reviews the line is 4.3, which is why this row is the best value in the folder at that price. You can mulch or use a 35 L bag, and the bullets include a spare blade. Reviewers say it is light enough for a small garden at 11.1 kg, easy to assemble, and that about 25–30 minutes covers a modest front and back. The lowest setting is not low enough for some owners, and the bag needs regular emptying. The height bullet is 25–65 mm in five levels, while the table prints a minimum of 25 centimetres, so that range is not settled. Charging is a separate complaint: reviews describe many hours, including 9.4 hours and an overnight charge, a battery dead on arrival, and a charger lead with no mains adapter. The listing does not state a BS 1363 plug.
Pros
Cons
Best for: You want a 33 cm mower that can bag or mulch, around £110, with a review count in the hundreds.
Less suitable: You need a settled millimetre height, a fast charge, or a charger whose UK plug is stated on the listing.

Does this listing say the mower is self-propelled?
No. The listing does not state a driven axle. Treat it as a push mower unless a later listing states one.

The title includes a 5.0 Ah battery. Reviews dispute the charger lead, and the listing does not state a BS 1363 plug.
The Forte CLMF2434F-04 is £99.99 with a 34 cm cut, a 21.6 V 4.0 Ah battery, a charger described as one hour, and a 32 L grass box with a full indicator. Across 82 reviews the line is 4.3. It is the only mower in this set whose bullets include a rear roller, and the listing says the handles fold, the box folds flat and it can be stored upright. Height is 20–70 mm in 10 mm steps in the bullets and 22–72 mm across six positions in the table. Reviewers with limited mobility found it manageable and said it coped with a long, damp first cut, and some called it reliable over a year. Others found the grass-box lid springs off, the box fiddly to build, the cut not close enough, and the charge nearer two hours than the one hour on the listing. One owner called it a little heavy at 11.4 kg, a mowing time is not stated, and the warranty line is one year on the mower and the battery, with a UK helpline in the bullets.
Pros
Cons
Best for: You want a bag and a rear roller around £100, and you can live with a small review sample of 82.
Less suitable: You need a stated runtime, a mulch plug, or a lid that stays on the box without fuss.

The Greenworks 2516107UA, also listed as GD24LM33K2, is £199.99 with a 33 cm cut, a 24 V 2 Ah pack and charger, and a claim of up to 140 m² on a single charge. Across 1,544 reviews the line is 4.2. You can use a 30 L bag or mulch, height is 25–70 mm in five positions, and the weight is 10.8 kg, which reviewers call light for a 33 cm mower. The table prints battery average life as 150 metres rather than a time, so there is no minute figure to quote from that cell. Some reviews say it is enough once a larger pack is used, and that it replaces a cable. The supplied 2 Ah pack runs out quickly in other reviews, including one owner who reported about seven minutes, with cut-outs until a second charge or a 4 Ah pack. Handle assembly is fiddly, and an earlier unit had a faulty switch and was returned. The bullets state a three-year product warranty and a two-year battery warranty.
Pros
Cons
Best for: You want bag or mulch on a 33 cm deck, you can add a larger 24 V pack, and you want a review count in the thousands.
Less suitable: You expect the included 2 Ah pack to finish a lawn without a second charge.

The LIGO GY2150 is the lowest shelf price here, £81.19, with 33 cm in the title, a 25 L grass bag, and two 20 V 2.0 Ah packs plus a fast charger. Across 89 reviews the line is 4.2. The bullets say small gardens under 300 m², about 35 minutes and a one-hour charge for each pack, while the table prints a one-hour runtime, so those times are not the same claim. Cutting height is unresolved: the bullets say 30 cm to 60 cm, the table says about 0.98–2.17 inches, the title says three heights and the table says five. Width is 33 cm in the title and 13.39 inches in the table. An older reviewer replacing a cabled mower called it light, at 8 kg, and reviews say it folds. Owners say it does not cut short enough, including grass several inches high, and that it struggles unless the lawn is small, flat and smooth.
Pros
Cons
Best for: You want two small packs and a bag at the bottom of this price list, and you can check the height figures on the live page before you rely on them.
Less suitable: You need a settled cutting height, a short cut, or a lawn that is not small, flat and smooth.

Common questions
Does this listing say the mower is self-propelled?
No. The bullets say it glides like a self-propelled mower, which is not a driven axle. Treat it as a push mower.
What cutting width and clippings setup does the listing give?

Are the battery and charger in the box?
The listing includes two 20 V 2.0 Ah batteries and a fast charger. It does not state a BS 1363 plug.
The Gtech SLM50 is £129.00 with a 25 cm cut, also written as 10 inch, and the title states 30 minutes of runtime on 18 V. Across 282 reviews the line is 4.0. Reviewers who mention a bad back or shoulder say they can lift it with one hand, and the bullets put the assembled weight at 3.5 kg while the table prints 3.2 kg. The listing gives only two cutting positions, and the table prints them as 2–10 cm. Several owners say it will not cut short enough, that the safety button is hard to keep pressed, and that it stops or cuts out in longer grass. Reviews describe mulch with no box to empty, and they say a battery pack and plug are in the box even though the bullets do not itemise the pack. One unit stopped after about a year, one first unit had a faulty handle catch and was replaced, and the battery is described as dying on longer grass.
Pros
Cons
Best for: You must lift the mower with one hand, the lawn is a very small patch, and you are happy to mulch rather than box the clippings.
Less suitable: You want a short summer cut, a grass box, or a mower that keeps going in grass left long.

The Murray MU-BAT-LM33-KIT is £141.56 for a 33 cm, 20 V 4 Ah brushless mower, with 2,900 rpm in the bullets and 40 minutes in the table. Across only six reviews the line is 2.7, the lowest star line in this set, so the listing score is 48. One UK review says only “Great lawnmower”, with no feature named, and no second UK review names something that worked. The title says a 32 L catcher with mulch and rear discharge, while the bullets say a 30 L net catcher, so the box size is not one figure. Cutting height is 25–75 mm in five positions, and the weight is 12.3 kg. Assembly required is listed as No. A defect note says the battery would not charge after two hours on the mower. Six reviews cannot tell you how a second summer goes.
Pros
Cons
Best for: You already know this kit and you are only checking the printed modes, not looking for a review record.
Less suitable: You want a star line you can lean on, or a single agreed figure for the catcher.

Twelve amazon.co.uk listings are on this page. Shelf prices, stars and review counts are the figures already on those listings. This is not a lab test. Each score is a sort key from the star line, the review count and a small-lawn fit flag. No percentage split is published for those checks, so the buying order below is unweighted. The top pick is the listing with at least 4.3 stars, at least 200 ratings, and a seller area at or under 100 m² or a cutting width at or under 25 cm. The best value is the lowest shelf price among listings with at least 4.2 stars and 200 ratings.
Lawn area and cutting width
30%Your lawn in square metres comes first. The seller's area is only a ceiling. About 22–25 cm suits a strip or a pitch, about 32–34 cm a typical small front and back, and 37–40 cm an open lawn.
Watt-hours and runtime
25%Energy is watt-hours, not the voltage on the carton. Roughly 72 Wh for 18 V 4.0 Ah, 48 Wh for 24 V 2.0 Ah, and 160 Wh for two 20 V 4.0 Ah packs. An up-to minutes line is a light-grass ceiling, not a measurement.
Clippings
20%A box suits a clear lawn. A mulch plug suits little-and-often cutting. If one line says no bag and another mentions a box, the carton is unresolved.
Cutting height
15%These rotaries often bottom around 20–30 mm. The RHS puts ordinary lawns at 13–25 mm in summer and up to 40 mm in spring and autumn. Fine lawns at 6–13 mm need another tool.
Weight
10%About 3–6 kg is a mower you can lift or use one-handed. About 11–15 kg is a normal 33–37 cm rotary. A table and a bullet that disagree stay unresolved.
Battery kit
%Look for a battery, a charger, and a platform you already own. These listings do not print BS 1363. A 40 V badge does not by itself mow more than an 18 V 4.0 Ah pack.
Review volume
%Hundreds of ratings are not the same fact as 4.5 from two ratings. A thin sample does not outrank a thick one on stars alone.
Drive
%No listing in this set states a driven axle. Automatic, or a line that says the mower glides like a self-propelled mower, is not drive.
Match the lawn first, then the width, then watt-hours, then a box or a mulch plug. A seller's square metres and an up-to minutes line are ceilings, not measurements.
A cordless lawn mower for small gardens is a battery rotary you push. You cut a terrace, a front lawn or a modest back garden without a mains lead across the path. People usually buy one to replace a petrol mower they do not want to store fuel for, or a corded mower whose cable catches. Three types cover the category. Narrow mulchers, about 22–25 cm and under about 6 kg, suit tiny areas and leave clippings down. Standard push rotaries, about 32–34 cm and about 8–14 kg, box, mulch, or both.
A 37–40 cm deck finishes an open rectangle faster and is clumsier in a tight space. A seller area up to 550 m² is a medium-lawn claim, even when the search was for a small garden.
Up to 45 minutes, and a seller's square metres, are ceilings on favourable grass. A 2 Ah pack can run out in a few minutes in other owners' reviews. Which? saw cordless runtimes from about 10 minutes to more than 40.
No listing in this set states a driven axle. A line that says the mower glides like a self-propelled mower is still a push mower. If the bank is too steep, stop.
Your lawn in square metres comes first. The seller's area is only a ceiling. Ceilings in this kind of set run from about 50 m² to 200 m², and a 37 cm listing can still be written for medium gardens up to 550 m². Cutting width is the next check. About 22–25 cm suits a strip or a pitch. About 32–34 cm suits a typical small front and back. Choose 37–40 cm only if the lawn is open. A wider deck finishes an open rectangle faster and is clumsier in a tight space.
Watt-hours, not the voltage badge, are the energy comparison. Roughly 72 Wh for 18 V 4.0 Ah, 48 Wh for 24 V 2.0 Ah, and 160 Wh for two 20 V 4.0 Ah packs. Which? averaged 22 minutes across tested cordless mowers, from about 10 to more than 40. Up to 45 minutes is a light-grass ceiling. A box suits a clear lawn. A mulch plug suits little and often. No bag and a 30 L box on one listing is unresolved, so do not pick a figure. These rotaries often bottom around 20–30 mm.
Three typical situations, each with a recommendation from this comparison.
You have a tiny area and you may have to lift the mower with one hand. The Gtech SLM50 is the light listing here, about 3.2 kg in the table or 3.5 kg in the bullets, and it mulches. Several owners say the short setting is still too long.
You want about 32–34 cm and a way to bag or mulch. The Litheli is the best value row, at about £109.99, with 4.3 from 684 reviews, a stated 5.0 Ah pack and a 35 L bag or mulch. The height lines do not agree.
Stay on a voltage you already use. The Einhell GE-CM 18 takes an 18 V 4.0 Ah Power X-Change pack and has 4.3 from 7,288 reviews. The bullets say no collection bag, while a highlight mentions a 30 L box, so confirm the carton.
The top pick is the swift EB122C, listing score 88, at about £134.99, with 4.5 from 330 amazon.co.uk reviews. It is a 22 cm mulch-only rotary listed for up to 50 m², with a 40 V 2.0 Ah pack, and the height only runs 30–50 mm. The best value is the Litheli U20LM00-4U120-QL-UK-002 at about £109.99, listing score 79, with 4.3 from 684 reviews, a 33 cm cut and a 35 L bag or mulch. The height bullet and the table do not agree, and reviews describe long charge times. These are the shelf prices on these listings, not a promise of the next price.
