Small lawn, lead or a pack
You have a small lawn and you can use a lead or a 5.0 Ah pack. The Litheli 20 V 33 cm is a 2-in-1 with a 35 L box and the battery in the carton, at about £109.99. Treat the 30-minute bullet as a claim.
Mulching lawn mower comparison 2026
The best mulching lawn mowers, compared.
Top pick: Swift EB122C Best value: LawnMaster MEH1633M-01 – Lowest shelf price in this set, about £69, for a 33 cm hover that mulches and does not collect. The sample is only 48 reviews. Updated 23 October 2026.
A mulching lawn mower is a rotary that recuts clippings and drops them back into the sward. You buy one in the UK when you would rather return a fine layer of grass than bag every cut. The Royal Horticultural Society describes that layer as a way to return some nutrients and help the soil hold moisture, if you mow little and often and take off no more than about a third of the leaf. A useful listing names a mulch plug, a wedge or a mulching deck. Rear discharge on its own is not a mulch plug. Match the cutting width to the lawn and to the gates you must pass, and treat a maker's square-metre line as a claim. Corded machines for UK mains are 230 V with a BS 1363 plug and an RCD. A cordless carton should include the battery if there is no lead. Hover mulchers do not collect, and you should not mow wet grass. The cutting habit is set out in the [how to mulch guide](/hub/lawn-and-garden-equipment/mulching-lawn-mower/sub/mulching-lawn-mower-how-to-mulch).

How big is the lawn?
The best mulching lawn mowers in detail
Our view
The Swift EB122C is £134.99 with 4.5 from 330 amazon.co.uk reviews. Bullets state a 22 cm super-mulch deck, a 40 V 2.0 Ah battery and fast charger, about 35 minutes and lawns up to 50 m², 5.2 kg, and three heights from 30 to 50 mm. There is no grass-box capacity because the design is mulch, not collect. An item highlight mentions five heights while a bullet says three, so the height count is inconsistent on the page. Reviewers describe it as light enough for a small patch, a caravan awning or a steep bank, and they like not emptying a box. A minority report the trigger failing or having to scrape mulch off the deck. The 50 m² and 35-minute lines are listing claims. It is the right odd tool for a tiny lawn. It is pointless on a wide rectangular lawn where a 33–38 cm deck finishes in fewer passes.
Pros
- 22 cm super-mulch deck, no box to empty
- 40 V 2.0 Ah battery and fast charger included
- 5.2 kg and a listing area up to 50 m²
- 4.5 from 330 reviews, often from small or awkward patches
Cons
- 22 cm means many passes on anything but a tiny lawn
- Height count disagrees on the page (bullet says three, highlight says five)
- A few reports of the trigger failing
- Mulch builds under the deck and needs scraping
Best for: A very small, awkward or sloping patch, or a second mower for edges the big deck misses, where mulch and 5.2 kg matter more than width.
Less suitable: A normal rectangular lawn where 22 cm is just slow, and anyone who must collect clippings.

Common questions
Does this mulch, or only collect?
The bullets state a 22 cm super-mulch deck and there is no grass box, because the design is mulch rather than collect. That is the listing claim, not a measured mulch fineness.
What power does it use, and is a battery in the box?
It is cordless 40 V. The bullets include a 2.0 Ah battery and a fast charger. About 35 minutes and lawns up to 50 m² are listing claims.
How wide is the cut, and how many height steps are listed?
The cut used here is 22 cm. A bullet says three heights from 30 to 50 mm, while an item highlight says five, so the count is not clean. Weight is 5.2 kg. Brushless is stated.
Our view
The Worx WG737E is £229.00 with 4.5 from 207 amazon.co.uk reviews. The highlight states a brushless IntelliCut motor, 2-in-1 mulch and bag, six height steps, two 4.0 Ah batteries and a charger, a 37 cm cut and a maker claim of up to 550 m². No grass-box litre figure appears in the bullets read for this comparison. Reviewers talk about the motor picking up on thicker grass, about finishing a lawn on one charge, and about the mulcher spreading clippings. The grass-box handle falling off is a repeated concrete complaint, and long or wet grass is where the deck clogs. Two hundred and seven reviews is a real sample but much smaller than the Einhell 43 cm listing. Choose it for a 37 cm cordless mulch-or-bag cut with batteries included. Skip it if you need a stated box capacity before you buy.
Pros
- 2-in-1 mulch and bag, six heights, 37 cm cut
- Two 4.0 Ah batteries and a charger in the highlight
- 4.5 from 207 reviews
- Reviewers describe the motor picking up in thicker grass
Cons
- No litre capacity stated for the grass box
- Grass-box handle reported falling off
- Clogs when grass is long or wet
- 207 reviews is a smaller sample than several rivals
Best for: A lawn that suits a 37 cm cordless deck with two 4.0 Ah packs and a mulch-or-bag deck, if you do not need a stated box volume.
Less suitable: Buyers who will not purchase without a litre figure for the box, and lawns that are often long and wet.

Common questions
Does this mulch, or only collect?
The highlight states 2-in-1 mulch and bag. No litre figure for the bag appears in the bullets read here. That is the listing claim, not a measured mulch fineness.
What power does it use, and is a battery in the box?
It is cordless, and the highlight states two 4.0 Ah batteries and a charger. The up to 550 m² line is the maker's claim. 207 reviews is a smaller sample than several rivals.

The cut used here is 37 cm, with six height steps. Brushless is stated. Weight is 15.3 kg. Reviewers report clogs when the grass is long or wet.
Our view
Einhell's 36 V cordless mower, style name 34 cm, is £237.99 with 4.4 from 2,005 amazon.co.uk reviews. A bullet recommends it for up to 300 m² with a 34 cm cut, a 30 L basket and five heights, and the title includes two batteries and two chargers. A technical-details line on the same page says 36 cm, so width is not clean. The bullets do not use the word mulch, but UK reviews describe a mulching plug fitted in the carton and complain that the instructions do not explain it. Praise clusters on weight, battery duration and folding. Criticism clusters on fiddly assembly and plastic parts. Buy it when you want two 36 V packs and a mulch option on a 34 cm deck. Do not buy it expecting the plug to be obvious on day one.
Pros
- Two batteries and two chargers in the title
- 30 L basket, five heights, bullet area up to 300 m²
- 4.4 from 2,005 reviews
- UK reviews describe a mulching plug in the carton
Cons
- The bullets never say mulch; the plug is described in UK reviews
- Instructions for the plug are criticised
- 34 cm in the bullet and 36 cm in the attribute line
- Plastic assembly complaints
Best for: Someone who wants two 36 V batteries included and a 30 L basket, and who has read that the mulch plug is real but poorly explained.
Less suitable: Buyers who need the word mulch in the bullet list before they trust the feature, and anyone put off by fiddly plastic assembly.

Common questions
Does this mulch, or only collect?
The bullets do not use the word mulch. UK reviews describe a mulching plug in the carton and say the instructions do not explain it. There is a 30 L basket. That is not a measured mulch fineness, and this row is not a bullet-listed mulcher.
What power does it use, and is a battery in the box?
It is cordless 36 V. The title includes two batteries and two chargers. Model number on the listing is 3413222.
How wide is the cut, and how many height steps are listed?
The cut used here is 34 cm, from the bullet. An attribute line on the same page says 36 cm, so do not average them. Five height steps are listed. Weight is 13.9 kg.
Our view
Litheli's 20 V cordless mower is £109.99 with 4.3 from 684 amazon.co.uk reviews. The title states a 33 cm cut, five heights from 25 to 65 mm, a 35 L box and a 5.0 Ah battery in the carton, and a bullet states a 2-in-1 mulch or collect choice. The model line is U20LM00-4U120-QL-UK-002 and the weight line is 11.1 kg. Reviews most often call it light and easy, with a smaller cluster mentioning a quiet cut or a battery that lasted their session. Assembly and a plasticky feel are the repeated reservations, and short runtime is mentioned but is not the main theme in the UK reviews read here. The bullet's up to 30 minutes is a listing claim, not a stopwatch result here. It suits a small lawn if you want mulch or collect on one cheap cordless deck. It is the wrong tool for a large, thick, wet sward.
Pros
- 2-in-1 mulch or 35 L collect, 5.0 Ah battery in the box
- 33 cm cut and five heights from 25 to 65 mm
- 4.3 from 684 reviews, often called light
- Bullet claims up to 30 minutes, which you should treat as a claim
Cons
- Runtime is a listing claim, and some reviews find the pack short
- Assembly and plastic build are the repeated doubts
- Not the tool for long, wet grass
Best for: A small lawn and a buyer who wants mulch or collect, a 5.0 Ah pack in the box, and a price under £110.
Less suitable: Large, thick or regularly wet lawns, and buyers who need a rear roller.

The Hyundai HYM3800E is listed at £158.31 with 4.2 from 3,914 amazon.co.uk reviews, a 38 cm cut, a rear roller, a 40 L box and a stated mulching feature. The bullets give 1,600 W, five heights and a 10 m cable. Reviewers often describe it as light enough for a sloping, uneven small garden and they mention the roller when they want stripes. Assembly and the height or wheel hardware come up as the practical annoyances, not a failed motor. The listing does not include a measured noise figure, so the outdoor-equipment label on the machine is what you should read, not a neighbour promise. Choose it when you want a corded mulching rotary with a roller and a large UK review sample. Skip it if you refuse to manage a mains lead.
Pros
- Rear roller plus a stated mulching feature
- 40 L box, 1,600 W, 10 m cable, five heights
- 4.2 from 3,914 amazon.co.uk reviews
- Often described as manageable on a sloping small garden
Cons
- You are tied to a mains lead
- Assembly and wheel or height hardware draw complaints
- No measured noise figure in this comparison
Best for: A small or sloping lawn where a rear roller, a mulch setting and a 40 L box matter, and a mains lead is acceptable.
Less suitable: Cordless-only buyers, and anyone who needs collection without learning a mulch setting.

Common questions
Does this mulch, or only collect?
The listing states a mulching feature and a 40 L grass box. It also has a rear roller, which is for stripes rather than for the mulch itself. That is the listing claim, not a measured mulch fineness.
What power does it use, and is a battery in the box?
It is corded 230 V, 1,600 W, with a 10 m cable in the bullets, so there is no battery. Use an RCD and one outdoor extension, fully unwound. Do not daisy-chain leads.
How wide is the cut, and how many height steps are listed?
The cut used here is 38 cm, with five height steps. Weight is 13.8 kg. This file has no measured noise figure, so read the label on the machine.

Greenworks lists the GD24LM33, model 2516107UA, at £199.99 with 4.2 from 1,544 amazon.co.uk reviews. The title pairs a 33 cm cut and a 30 L bag with a 24 V 2 Ah battery and charger, and a bullet states five heights from 25 to 70 mm plus 2-in-1 mulch or collect for lawns up to 140 m². Weight is 10.8 kg. Reviewers dwell on how light it is, on battery life for a small lawn, and on the folding handle. A minority mention wheels, plastic or assembly. The 140 m² figure is the maker's claim on the listing. It fits a smaller UK lawn where you already like the idea of a 24 V family and you will mulch in dry weather. It is less convincing if your grass is routinely left long, which is where reviewers say cordless decks struggle.
Pros
- 2-in-1 mulch or 30 L collect, 24 V 2 Ah battery and charger included
- 33 cm, five heights 25–70 mm, listed to 140 m²
- 4.2 from 1,544 reviews
- Folding handle and a light deck in the reviews
Cons
- Listed for smaller lawns up to 140 m², not a large garden
- Only a 2 Ah pack in this SKU
- Wheels, plastic and assembly appear as secondary complaints
Best for: A smaller lawn within the listing's 140 m² claim, with mulch or a 30 L bag on a 24 V deck.
Less suitable: Lawns well beyond 140 m² on this 2 Ah SKU, and anyone who wants a roller stripe.

The Swift 40 V 2 Ah cordless mower is £139.99 with 4.2 from 1,287 amazon.co.uk reviews. Bullets state a 32 cm cut, a 30 L box, mulching, five heights from 20 to 60 mm, and a battery plus charger. An attribute line also says 13 inches, which does not match 32 cm, so treat the title and bullet as the cut you are buying and the inch line as unresolved. The highlight claims about 200 m². Reviewers call it light and are glad to drop the mains lead; several say the grass box is awkward and at least one reports the box missing on arrival. Battery life is praised for small lawns and criticised when the lawn is larger than the pack. One review says the battery would not charge after eight months, which is a single report, not a failure rate. It is a mid-price 40 V mulch-or-collect mower for a small lawn. It is a weak choice if you need a documented runtime beyond the listing.
Pros
- 32 cm cut, 30 L box and a stated mulching function
- 40 V 2 Ah battery and charger included
- Five heights listed from 20 to 60 mm
- 4.2 from 1,287 reviews and often praised for dropping the cable
Cons
- 32 cm in the title versus 13 inches on an attribute line
- Grass box assembly, and a report of a missing box
- Battery complaints once the lawn outgrows the 2 Ah pack
Best for: A small to medium patch where 32 cm, a 30 L box and a 40 V 2 Ah pack are enough, and you can live with the inch and centimetre clash on the page.
Less suitable: Anyone who needs one unambiguous cut width, or a lawn that has already outrun a 2 Ah pack in these reviews.

The Einhell 43 cm cordless mower, highlight GE-CM 43 Li M, is £239.94 with 4.1 from 6,758 amazon.co.uk reviews, the largest sample in this set. Bullets state 36 V, two 4.0 Ah batteries, two fast chargers, a 63 L bag, six heights, a mulching wedge and a maker area of up to 600 m². One reviewer quotes 90 dB(A) off the box; this comparison did not remeasure it. The dominant complaint is assembling the plastic grass box, including snapped clips, and several people say it dislikes anything but dry grass. It is also described as quiet and light compared with an old petrol mower. The mulching wedge is praised when people use it. This is the wide-deck cordless option when you will collect a lot and mulch on dry weeks. It is a frustrating buy if you hate clipping a large plastic box together.
Pros
- 43 cm cut, 63 L bag, six heights, mulching wedge included
- Two 4.0 Ah batteries and two fast chargers
- 4.1 from 6,758 reviews, the largest sample here
- Reviewers often call it quiet versus an old petrol mower
Cons
- Grass-box assembly is the main complaint, including snapped clips
- Poorly suited to wet grass in the reviews
- Highest price in this set at £239.94
Best for: A larger lawn in this set, up to the listing's 600 m² claim, where a 63 L bag and a mulching wedge are both useful and you will assemble the box patiently.
Less suitable: People who hate clipping a large grass box together, and anyone mowing wet grass as the normal condition.

Common questions
Does this mulch, or only collect?
The bullets state a mulching wedge and a 63 L bag. Reviewers praise the wedge when they use it. That is the listing and the reviews, not a measured mulch fineness.
What power does it use, and is a battery in the box?
It is cordless 36 V. The bullets state two 4.0 Ah batteries and two fast chargers. The up to 600 m² line is the maker's claim. Model number on the listing is 3413130.
How wide is the cut, and how many height steps are listed?
The cut used here is 43 cm, with six height steps. Weight is 16 kg. One reviewer quotes 90 dB(A) off the box. This comparison did not remeasure it, and that figure is not the regulatory sound-power cap.

The LawnMaster MEH1633M-01 is £69.00 with 4.1 from only 48 amazon.co.uk reviews. The title is a 1,600 W, 33 cm corded hover mower, non-collect, and the bullets say clippings are mulched back onto the lawn. Item type on the listing is Mulching Lawnmower. Four heights run from 12 mm to 33 mm and weight is 7.5 kg. Reviewers who have used it mention a light machine on a slope and a mulch that does not leave a box to empty. The sample is small, so the 4.1 is not a large-N result. There is no roller and no collection. It is the budget mulching hover for a small, bumpy lawn where you will cut often. It is the wrong mower if you need to remove clippings, stripe the lawn, or trust a review count in the hundreds.
Pros
- Hover mulch with no box, 33 cm, 1,600 W
- Four heights from 12 mm to 33 mm
- 7.5 kg and a low shelf price of £69.00
- Listing item type is Mulching Lawnmower
Cons
- Only 48 reviews
- Cannot collect clippings or stripe with a roller
- Hover decks need a narrower pass in long grass, per RHS guidance on hover mowers generally
- Mains lead, and a very low 12 mm setting that can scalp bumps
Best for: A small bumpy lawn where you will mulch with a light hover and you do not need a grass box.
Less suitable: Anyone who must remove clippings, stripe with a roller, or rely on hundreds of reviews.

Common questions
Does this mulch, or only collect?
The title is a non-collect hover, and the bullets say clippings are mulched back onto the lawn. There is no grass box. That is the listing claim, not a measured mulch fineness.
What power does it use, and is a battery in the box?
It is a corded hover, listed at 1,600 W, so there is no battery. It needs a UK 230 V supply and an RCD. This file does not show whether your outdoor socket already has one.
How wide is the cut, and how many height steps are listed?
The cut used here is 33 cm, with four heights from 12 mm to 33 mm. There is no rear roller. The 12 mm setting can scalp bumps. Weight is 7.5 kg.

Across 1,315 amazon.co.uk reviews the Murray 1600 W corded mower sits at 4.0 and £152.65, with a 38 cm cut, five heights from 25 to 65 mm and a 45 L box. The bullets describe a 2-in-1 choice: collect, or rear-discharge clippings. Reviewers who mention the mulching attachment often call it awkward to fit, and several say the grass box comes off in use. The same reviews still credit a useful cut on a modest lawn and a fairly light push. The listing claims lawns up to 500 m², which is the maker's figure, not a timed test in this comparison. You get a 10 m cable in the bullets and a BS 1363 plug problem if you only have a short indoor lead. It is a sensible corded mulch-or-collect mower when you will mow little and often; it is a poor fit if you wanted a plug that clicks in without a fight.
Pros
- 2-in-1 collect or rear discharge on a 38 cm, 1,600 W deck
- 45 L box and five heights from 25 to 65 mm in the bullets
- Reviewers credit a useful cut and a fairly light push
- Large UK sample: 4.0 from 1,315 reviews
Cons
- Mulching attachment described as awkward to fit
- Grass box reported falling off in use
- Mains lead to manage on a 10 m cable
- Maker's 500 m² claim is not a test in this comparison
Best for: A modest lawn where you want 1,600 W corded power, a 45 L box, and the option to drop clippings, and you will fit the mulch plug carefully.
Less suitable: Anyone who wants a mulch plug that reviewers found easy, or who will not manage a cable.

Common questions
Does this mulch, or only collect?
The listing describes a 2-in-1 choice: collect into a 45 L box, or rear-discharge the clippings. Reviewers who mention the mulching attachment often call it awkward to fit. That is the listing and the reviews, not a measured mulch fineness.
What power does it use, and is a battery in the box?
It is corded 230 V, 1,600 W, so there is no battery. The bullets include a 10 m cable. You still need a UK outdoor socket with an RCD. This file does not show whether your socket already has one.
How wide is the cut, and how many height steps are listed?
The cut used here is 38 cm, with five heights from 25 to 65 mm. A rear roller is not stated. Brushless is not stated. The listing's lawns-up-to-500 m² line is the maker's claim.
Our view
Hyundai's 20 V brushless cordless mower is £125.99 with 3.9 from 51 amazon.co.uk reviews. The title states 33 cm, 3-in-1 collect, drop and mulch, a 32 L bag, five heights, and a battery and charger, plus a three-year warranty line. The attribute width is 330 mm, which matches 33 cm. Fifty-one reviews is a thin sample next to the corded Hyundai on 3,914. In the UK reviews read here, people mention a light, quiet push and a battery that sometimes runs short. Plastic and assembly appear, but not as a flood. Treat the star line as early, not settled. It is a reasonable 3-in-1 if you want all three discharge modes at this price and can accept a small review count. It is a weaker pick than the £109.99 Litheli if you mainly want more reviews on a similar 33 cm cordless deck.
Pros
- 3-in-1 collect, drop and mulch
- 33 cm, 32 L bag, five heights, battery and charger included
- Three-year warranty line on the listing
- Light and quiet in the small review set
Cons
- Only 51 amazon.co.uk reviews
- 3.9 stars, the lowest in this set
- Some comments on short runtime
- Less review evidence than the Litheli at a similar width
Best for: A buyer who specifically wants collect, drop and mulch on a 33 cm cordless mower and accepts a 51-review sample.
Less suitable: Buyers who want a large review sample before they trust a 3.9-star line.

Common questions
Does this mulch, or only collect?
The title states 3-in-1 collect, drop and mulch, with a 32 L bag. That is the listing claim, not a measured mulch fineness. The review sample is 51.
What power does it use, and is a battery in the box?
It is cordless 20 V brushless, and the title includes a battery and a charger. Fifty-one reviews is a thin sample next to the corded Hyundai on the same brand.
How wide is the cut, and how many height steps are listed?
The cut used here is 33 cm. An attribute width of 330 mm matches that. Five height steps are listed. Weight is 10.3 kg.
How we compared
Eleven amazon.co.uk listings were scored on 22 October 2026 from the star rating, the review-sample band, the stated specification and the shelf price. Those four parts add up to 100. A thin review count cannot outrank a large UK sample on stars alone, and a higher shelf price scores less on value. This is not a laboratory cut test.

Mulching lawn mower buying guide
Choose the clipping path first, then the width, then whether the carton is a 230 V lead or a battery that is actually in the box. Square-metre lines from the maker stay claims. Nothing below is a laboratory cut.
What is a mulching lawn mower?
A mulching lawn mower is a walk-behind rotary that chops clippings again and drops them into the lawn. Some machines only mulch. Others keep a grass box, so you collect when the grass is long or wet and mulch when it is short and dry. The Royal Horticultural Society treats that fine layer as a way to return some nutrients and help the soil hold moisture. The condition is little and often, on dry grass, taking off no more than about a third of the leaf.
Best for
- Small lawns that can take a lead or a battery pack
- Larger patches that want a wide cordless deck and two batteries
- Bumpy small lawns where you will mulch and will not collect
Not ideal for
- A collection-only mower bought from a mulching search
- Steep banks beside water, or wet grass as the normal condition
Mistakes to avoid
- 1
Buying a collector from a mulching search
A grass box or rear discharge is not a mulch plug. Read the title, the bullets or a clear UK review for a plug, a wedge or a mulching deck. If the bullets never say mulch, say so, even when reviews describe a plug.
- 2
Trusting a square-metre claim
Which? and The English Garden do not give the same width bands, and a maker's up to 600 square metres line is not a test in this comparison. Measure the lawn and the gates, then treat the area figure as a claim.
- 3
Mulching long or wet grass
Mulch little and often, on dry grass, and do not take off more than about a third of the leaf. Long or wet grass belongs in the box, or it should wait. Do not mow in the wet, and do not daisy-chain extension leads.
What to weigh up
Mulch mode
HighStart with the clipping path. A dedicated mulcher, a 2-in-1 collect-or-mulch machine and a 3-in-1 collect, drop and mulch machine are different tools. Rear discharge is not a plug. If the bullets never say mulch, do not treat the search title as proof. UK reviews may still describe a plug in the carton, and the honest line is that the evidence is those reviews, not the bullet list. Hover mulch means no box and no roller. Fit a plug only on dry, short grass.
Width and supply
HighWidth against the lawn and the gates comes before voltage. Under about 35 cm is the small-lawn band in one consumer guide, and about 35 to 45 cm is the band that guide gives for about 50 to 150 square metres. Another guide stretches 30 to 35 cm much further. Do not merge them into one rule, and do not treat a maker's area line as a test. Then choose the supply. Corded 230 V needs a BS 1363 plug, an RCD and usually one fully unwound outdoor extension.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
Wider cordless deck
You want a 37 to 43 cm cordless deck and two batteries. The Einhell GE-CM 43 Li M states a 43 cm cut, a 63 L bag, a mulching wedge and two 4.0 Ah packs. The up to 600 m² line is the maker's claim, and the plastic box is the main complaint.
Bumpy lawn, no box
You have a small bumpy lawn, you will mulch, and you will not collect or stripe. The LawnMaster MEH1633M-01 is a 33 cm corded hover at about £69. The sample is 48 reviews, so the 4.1 is not a large result.
Common questions about mulching lawn mowers
What is a mulching lawn mower?
A mulching lawn mower is a rotary that recuts clippings and drops them back into the lawn. The Royal Horticultural Society describes that fine layer as a way to return some nutrients and help the soil hold moisture, if you mow little and often on dry grass and take off no more than about a third of the leaf. Rear discharge is not automatically a mulch plug. Look for a plug, a wedge or a mulching deck in the title, the bullets or a clear UK review.
How wide a cut do I need?
Match the cutting width to the lawn and to your gates. Which? suggests under 35 cm for lawns up to about 50 square metres and about 35 to 45 cm for 50 to 150 square metres. The English Garden suggests 30 to 35 cm up to about 250 square metres. Those guides disagree, so use them as orientation. A maker's up to 600 square metres line is a claim, not a timed test. Decks in this set run from 22 cm to 43 cm, including one 33 cm hover.
Should I buy corded or cordless?
Corded machines here are 230 V with a BS 1363 plug. A 10 m lead often still needs one outdoor extension. Do not daisy-chain leads, use an RCD, unwind the reel, and do not mow wet grass. A cordless listing should include the battery if there is no lead. Do not compare volts across brands as if they were the same runtime. Battery-only decks in the same family are on the cordless mulching lawn mower comparison.
What noise limit applies to these mowers?
Lawnmowers with a cutting width of 50 cm or under have a permissible guaranteed sound power level of 96 dB under the Noise Emission in the Environment by Equipment for use Outdoors Regulations 2001, Schedule 3. That figure is the label on the machine, not a measurement at a neighbour's window. This comparison did not take its own noise readings. A reviewer's figure quoted off a box is not our measurement and is not that regulatory cap.
Does every listing in a mulching search actually mulch?
No. A collection-only rotary can appear in a mulching search. Check for a plug, a wedge or a mulching deck. One 34 cm cordless listing in this set never uses the word mulch in the bullets. UK reviews describe a plug in the carton and poor instructions, so do not treat that row as a bullet-listed mulcher. Hover machines in this set mulch and do not collect.
What should I pay on amazon.co.uk?
Shelf prices in the files dated 19 October 2026 sort this basket, not the whole market. Entry sits about £69 to £140, the middle about £150 to £200, and the upper band about £229 to £240. The score uses stars, sample size, specification and price. It is not a cut trial, and a one-point gap is not a measured difference in the grass. A qualifying purchase through our links can earn a commission at no extra cost to you.
When should I stop and call someone?
Call an electrician for a new outdoor socket or a missing RCD. Stop if the cable, the deck or the battery pack is damaged. Do not mow wet grass, and do not take a pedestrian mower onto a steep bank beside water. Unplug, or remove the pack, before you clear the deck. Lithium packs show a crossed-out wheelie bin and do not go in household rubbish.
Our verdict
The top pick is the Murray LE380, at 85 out of 100 on stars, review sample, specification and shelf price. It is a corded 230 V, 38 cm, 2-in-1 mower at about £152.65, with 4.0 from 1,315 reviews, a 45 L box and five heights. Reviewers who mention the mulching attachment often call it awkward to fit, and several say the grass box comes off in use. The best value is the LawnMaster MEH1633M-01 at about £69, a 33 cm corded hover that mulches and does not collect, at 4.1 from 48 reviews. That sample is thin. The corded Hyundai HYM3800E sits one point behind the Murray, with 4.2 from 3,914 reviews and a rear roller. The score is not a cut trial.
