The best mulch mowers, compared.
Top pick: Swift EB122C Best value: Forte MEB1637E – Lowest saved price among kept mulch-plug listings with at least 30 reviews, about £79.99, at 4.1 from 33 reviews. Updated 23.10.2026.
A mulch mower is a walk-behind rotary that chops clippings and drops them on the lawn, usually with a plug that closes the chute to the grass box. In the UK you buy one for a lawn you already mow often, so less grass goes in the bin, and you still need a way to collect when growth is long, wet or diseased. Judge a listing by a stated plug or mulch mode, the cutting width, and whether a lead or a battery matches the garden. A plug is not the same as a shaped mulching deck, and cut-and-drop is not fine mulch. A corded mower needs an outdoor-rated lead, fully unwound, on a fused UK 3-pin plug, with an RCD. Read the cutting height in millimetres, and do not take more than about one third off in one pass. Do not assume the wheels are driven. Width, the plug and the power source are set out in our [mulch mower buying guide](/hub/lawn-and-garden-equipment/mulch-mower/sub/mulch-mower-buying-guide).

Personal buying guide
Question 1 of 2
How will you power it?
The Swift EB122C is £134.99, a 40 V 22 cm mower at 5.2 kg, with a 2.0 Ah pack and fast charger, mulch rather than a stated box, and three heights from 30 to 50 mm. The area bullet is up to 50 m². The listing line is 4.5 from 330 reviews. One saved review says the trigger failed at 13 months and the mower would not switch off until the pack was removed.
Pros
Cons
Best for: You want the lightest mower in this set for a very small or sloping lawn and you are happy to mulch.
Less suitable: You need a grass box, a cut below 30 mm, or a wide deck.
Specifications
Common questions
Does the Swift 22 cm collect grass?
A box volume is not stated. The bullet says a super-mulch blade leaves chopped clippings on the lawn. Reviewers describe little or nothing to pick up.
How many height settings does it have?
The bullets and the technical fields say three, from 30 to 50 mm. A highlight line says five heights. The three-step figures are the ones that match the fields.
What battery is in the box?
The bullet says a 40 V 2.0 Ah battery and a fast charger, up to 35 minutes, for lawns up to 50 m². One reviewer ran out halfway on a lawn of about 4 m by 8 m.
The WORX WG737E is £229.00, a 37 cm brushless mower powered as 40 V by two 20 V 4.0 Ah packs, with a charger, a mulch plug and a bag, and heights from 20 to 70 mm. The area bullet is up to 550 m². The weight field is 15.3 kg. The listing line is 4.5 from 207 reviews. Bag litres are not stated. Reviewers describe it as lighter than the petrol mowers they retired.
Pros
Cons
Best for: You already use WORX PowerShare and want a 37 cm mower with two 4.0 Ah packs in the box.
Less suitable: You need a roller, a known bag volume, or the lowest price.
Specifications
Common questions
How does the WORX make 40 V?
The bullets say two 20 V 4.0 Ah PowerShare packs together. A charger is included in that bullet. The stated area is up to 550 m².
Does it mulch?
Yes. The bullet says you switch between a mulch plug and a grass bag. Bag litres are not stated. The collection rate is stated as up to 90%.
Will the packs fit other WORX tools?
The bullet says the packs and charger work with WORX PowerShare 20 V, 40 V and 80 V tools. That only helps if you already use that system.
The Greenworks 40 V mower, model 2504707UC, is £269.16, with two 2 Ah packs and a charger, a 41 cm cut, mulch or a 50 L bag, and a stated area up to 500 m². The weight field is 20.8 kg. The listing line is 4.4 from 1,182 reviews, the highest star line in this set among listings with at least 500 reviews. Height figures conflict. Drive is not stated. An 18-month review says both packs failed.
Pros
Cons
Best for: You want the widest deck here, two packs in the box, and the strongest large review sample.
Less suitable: You need a light mower to lift, a 4 Ah pack, or a single agreed height range.
Specifications
Common questions
Why does this listing take the top-pick badge?
Among kept mowers with at least 500 amazon.co.uk reviews, 4.4 from 1,182 is the highest star line. The score is that star rating times 20, which is 88. The badge is a sort rule, not a lab test.
What batteries are in the box?
The included line lists two 2 Ah batteries and one charger. The bullet says each pack cuts 250 m² and the mower is for up to 500 m². Reviewers often say 2 Ah is the limit.
What is the cutting height?
Five positions are stated. The bullet says 25 to 80 mm. The maximum field says 70 mm. The minimum field says 25 centimetres. Those three figures are not combined into one range.
The Litheli is a 20 V cordless mower at £109.99 with a 33 cm cut, a stated 5.0 Ah pack, up to 30 minutes in the bullet, and mulch or a 35 L box. The listing line is 4.3 from 684 reviews. The height field of 25 cm conflicts with the 25 mm bullet. A charger is not named. One saved review received a dead battery.
Pros
Cons
Best for: You want a low-priced 33 cm cordless mower with a large stated pack for a small lawn.
Less suitable: You need a named charger in the listing, or a documented folding handle.
Specifications
Common questions
Is a charger in the Litheli listing?
The title includes a 5.0 Ah battery. The bullets do not name a charger, and there is no included-components line. Saved reviews disagree with each other about the charger, so the charger stays unknown.
What is the lowest cut?
The bullet says 25 to 65 mm across five positions. The technical field says a minimum of 25 centimetres, which conflicts with that bullet and with the 65 mm maximum.
Can it mulch?
Yes. The bullet says mulch mode or collection in a 35 L box.
The Hyundai HYM3800E is £158.31, a corded 1600 W mower with a 38 cm cut, a 10 m cable, a rear roller, a 40 L box and a mulch plug in the bullets. The area line is about 225 m². The listing line is 4.2 from 3,914 reviews, the largest sample here. Weight is 12.5 kg in the bullet and 13.8 kg in the field. Reviewers split on whether the plug is real mulch, and one review says a warranty repair was refused.
Pros
Cons
Best for: You want a corded roller mower with a huge review sample and a socket within 10 m.
Less suitable: You need cordless mowing, or you expect the plug to hide clippings on long grass.
Specifications
Common questions
Does the HYM3800E mulch?
The bullets describe a mulching plug that returns cuttings. The included-components line names the 40 L collector, the mower and a manual, and does not name the plug. Reviewers disagree on whether the result is fine mulch.
Is it self-propelled?
No. Drive is not stated. One reviewer wishes it were self-propelled. You push it.
Does the rear roller stripe the lawn?
The bullet says the roller can leave stripes. One saved review says the roller is light and the stripes do not last.
The Swift EB132CP2 is £139.99, a 40 V 2 Ah brushless mower with a stated 32 cm cut, mulch and a 30 L box, five heights from 20 to 60 mm, and a charger in the included line. The area bullet is up to 200 m². The listing line is 4.2 from 1,287 reviews. The width field says 13 inches. Saved complaints include a loose body part, a lost handle bolt, and a battery that died after three weeks.
Pros
Cons
Best for: You want a 32 cm Swift with the charger listed, for a lawn the bullet puts at up to 200 m².
Less suitable: You need a roller, a wide deck, or a mower that does not bounce on bumps.
Specifications
Common questions
Is the Swift 32 cm self-propelled?
The listing asks the question. The bullets do not say it is driven. The operation-mode field says Manual.
What comes in the box?
The included line lists one battery, one charger, the mower and a manual. The mulch bullet also describes a 30 L box.
Will the battery run other Swift tools?
Several reviewers say the 40 V pack also runs a Swift strimmer, blower or hedge trimmer. A compatibility table is not in the technical rows.
The Greenworks 24 V mower is £219.99, with a 4 Ah pack and charger, a stated area up to 260 m², mulch and a 30 L bag, and a title width of 33 cm. The weight field is 8 kg. The listing line is 4.1 from 145 reviews. The model number disagrees between title and technical rows. Saved reviews mention cut-out in dense grass, clogging when wet, and a handle that is short over 6 ft.
Pros
Cons
Best for: You want a light 33 cm Greenworks with a 4 Ah pack in the box for a smaller stated lawn.
Less suitable: You are tall and need a high handle, or the grass is often wet and thick.
Specifications
Common questions
Is a 4 Ah battery included?
Yes. The title and the bullets say a 24 V 4 Ah battery and a charger. The area bullet is up to 260 m² on one charge.
Which model number is it?
The title says MO24L411-01. The technical rows say MO24L411-00. A saved review writes M024L411-01. Both numbers are kept.
Is it self-propelled?
The listing asks. The bullets do not say the wheels are driven. The operation-mode field says Automatic, which is not read as self-propelled.
The Forte MEB1637E-04 is a corded 1600 W mower at £79.99, with a 37 cm cut, a stated mulch plug, a 40 L box, a rear roller and six heights from 20 to 70 mm. The listing line is 4.1 from 33 reviews, so the sample is small. It is the lowest saved price among kept mulch mowers with at least 30 reviews. Saved complaints include a blade that would not turn after two uses, broken side clips, and a stone chipping the blade.
Pros
Cons
Best for: You want a corded mulch plug and a roller, and the lawn is within 10 m of a socket.
Less suitable: You need a large review sample, or you do not want a lead across the lawn.
Specifications
Common questions
Does the Forte include a mulch plug?
Yes. The bullets say to use the supplied mulch plug so clippings are cut and returned, or to use the 40 L collector instead.
Does it have a rear roller?
Yes. The title and bullets state a rear roller for stripes. One saved review says the stripes do not last and the roller feels light.
How long is the cable?
The bullets state a 10 m cable and a 1600 W motor. A voltage figure is not printed in the technical rows.
The Hyundai HY20CLM33 is £125.99, a 20 V brushless 33 cm mower with collect, drop or mulch, a 32 L bag, and the battery and charger named in the title. Amp-hours are not stated. The runtime field says 40 minutes. The listing line is 3.9 from 51 reviews. Saved issues include an unthreaded assembly bolt and a grass box that is hard to seat.
Pros
Cons
Best for: You want a light 33 cm Hyundai with a plug and a named charger, and you can accept a short review history.
Less suitable: You need a stated amp-hour figure or a rear roller.
Specifications
Common questions
Does the HY20CLM33 include a battery?
The title says the battery and charger are included. An amp-hour figure is not in the bullets or the technical rows.
What are the three modes?
The bullets say cut and collect, cut and drop, or cut and mulch, and that a mulching plug is included. The bag is 32 L.
What do the grass combs do?
The bullet says combs on the deck edges guide grass into the blade so you can mow closer to walls and borders.
The Murray MU-BAT-LM33-KIT is £141.56, a 20 V 4 Ah 33 cm mower with rear discharge, collection or mulch, and a bullet height range of 25 to 75 mm. The bag is 32 L in the title and 30 L in the bullet. The listing line is 2.7 from six reviews. One UK review says the battery would not charge. A charger is not itemised.
Pros
Cons
Best for: You specifically want rear discharge as well as a mulch mode, and you accept a six-review listing.
Less suitable: You want a review history you can lean on, or a charger named in the box list.
Specifications
Common questions
Can the Murray mulch?
Yes. The bullets say rear discharge, grass collection or mulching. The title also says mulching and rear discharge.
Is a charger listed?
No included-components line is in the saved listing. The model name contains KIT and the bullet states a 20 V 4 Ah motor. A charger is not itemised.
What do the six reviews say?
One UK review says the battery would not charge after two hours. Another UK review only says great lawnmower. A third saved review is in Spanish. The 2.7 line is too small to treat as a pattern.
Ten amazon.co.uk listings are scored from the snapshot saved with this set, dated 19 October 2026. The score is the star rating multiplied by 20. That figure is the whole numeric score. It is not a laboratory mow. The top pick is the highest star line among kept listings with at least 500 reviews. Best value is the lowest saved price among kept listings that state a mulch plug or mulch mode and have at least 30 reviews.
Amazon stars
100%The amazon.co.uk star rating multiplied by 20. That is the whole numeric score. It is not a laboratory mow. The score note publishes no other criterion percentage, so this weight is 100 and it was not rescaled.
Choose the lawn before the badge. A lawn you already mow often is a different buy from wet or over-long grass, and a lead only works if the socket is within the cable.
A mulch mower is a walk-behind rotary that chops clippings and drops them, usually by fitting a plug that closes the path to the grass box. You buy one in the UK for a lawn you already mow often, so less grass goes in the green bin. You still need a way to collect when growth is long, wet or diseased. Warwickshire County Council treats a shaped mulching deck as a different machine from a collecting mower that only blocks the chute. Cut-and-drop is not fine mulch.
Mow dry grass, and do not take more than about one third of the height at once. The Royal Horticultural Society says not to mow in frost or on waterlogged soil. Warwickshire County Council says mow before the grass is about 8 cm if you will leave 4–5 cm. A plug does not retire the box when the grass is long, wet or diseased.
Height belongs in millimetres. A technical field that says 25 centimetres against a 25 mm bullet is a unit error, not a cutting height you can set. Do not combine a conflicting bullet, a maximum field and a minimum field into one range. If the figures do not agree, treat the height as unsettled.
No listing in this set states self-propelled drive. “Automatic” on an operation-mode line is not driven wheels. You push the mower. A 1600 W lead left coiled is a separate mistake: unwind it, use a fused UK 3-pin plug and an RCD, and stop if the lead, plug or charger is damaged or hot.
The mulch method is the first thing that decides whether a listing belongs in this comparison. Confirm a plug, a named mulch mode, or cut-and-mulch wording. Cut-and-drop is not fine mulch. Warwickshire County Council treats a shaped mulching deck as different from a collecting mower that only closes the chute with a plug, and reviews disagree on how fine the returned cuttings are. A hover, or a mower-and-trimmer pack with no mulch line, is a different product.
After the plug, read width, power and height, in that order. Narrow decks, from about 22 cm, suit a small or broken lawn and need more passes. A 37–41 cm deck suits a more open lawn. Corded models of this type are 1600 W with a 10 m cable, so the socket has to be within that lead. The cable must be outdoor-rated, fully unwound, on a fused UK 3-pin plug, and used with an RCD, and you mow dry grass. Cordless models are 20 V, 24 V or 40 V.
Three typical situations, each with a recommendation from this comparison.
You want a mower you can lift, and you will accept a narrow cut. The Swift EB122C is the lightest weight field in the set, 5.2 kg, with a 22 cm mulch blade and no stated box, at about £134.99. The listing line is 4.5 from 330 reviews. One reviewer ran out of the 2.0 Ah pack on a small lawn.
You have a socket within about 10 m and you want a roller plus a plug. The Forte MEB1637E is a corded 1600 W mower with a 10 m cable, a stated mulch plug, a rear roller and a 40 L box, at about £79.99. The listing line is 4.1 from 33 reviews, so the sample is small.
You want two packs and a wider deck, and you can lift the weight. The Greenworks G40LM41 is the 41 cm listing, with two 2 Ah packs, a charger and a 50 L bag, at about £269.16. The weight field is 20.8 kg. The listing line is 4.4 from 1,182 reviews. Height figures on the card do not agree.
The top pick is the Greenworks G40LM41. Among kept listings with at least 500 amazon.co.uk reviews, 4.4 from 1,182 is the highest star line, so the score is 88. It is about £269.16, with a 41 cm cut, mulch or a 50 L bag, and two 2 Ah packs. The weight field is 20.8 kg, and the height figures do not agree. Best value is the Forte MEB1637E at about £79.99, the lowest saved price among kept mowers that state a mulch plug and have at least 30 reviews, at 4.1 from 33 reviews. That sample is small. The score is the star rating times 20. It is not a laboratory mow.
