Best cordless mulching lawn mower for a UK lawn

Updated: October 2026

You want the best cordless mulching lawn mower, and you want a reason to walk away from each name. Magazine pages this year often test a different machine, including a self-propelled Worx that is not in this amazon.co.uk capture, so their winner is not a score you can paste onto these eleven rows. Here, best means a listing that states mulch, with a condition on lawn size, kit and who should skip it. The full table, prices in GBP and review counts sit on the [cordless mulching lawn mower comparison](/hub/lawn-and-garden-equipment/cordless-mulching-lawn-mower). Peter F. compared listings and review signals in October 2026. A qualifying purchase can earn a commission at no extra cost to you.

What best can mean on this shelf

There is no lab score in this set. The number beside each mower is the amazon.co.uk star line, and a 4.5 from 54 reviews is not the same evidence as a 4.3 from 7,288 when the listing also contradicts itself. None of these titles says the mower is self-propelled. A driven mower in a magazine round-up is a different product. The practical domestic machine can mulch fine clippings and can still collect. Warwickshire treats a collect-and-mulch deck as a compromise. Rows that never mention mulch are not the answer to this search. Seller area claims, from 50 m² to 550 m², stay claims. The buying guide teaches those forks.

Mulch and bag for a medium lawn

The Worx WG737E is the mulch-and-bag kit when the lawn is more than a courtyard. It is about £229.00, 37 cm, with a stated mulch plug, a grass bag and two 20 V 4.0 Ah packs, at 4.5 from 207 reviews. The up to 550 m² line is the seller’s figure. One reviewer still calls 4 Ah packs small on a large lawn. Skip it if you need drive, which is not stated. It is our top pick inside this set, not a laboratory win. The Bosch Rotak 18V-32 kit is about £181.00, 32 cm, with a plug, a 35 litre bag and one 4.0 Ah battery, at 4.5 from 54 reviews. One reviewer covers about 60 m² in 20–25 minutes and wants a second pack. The battery release is fiddly. Skip it when you want the spare pack in the carton. A lawn you carry is a different fork. The Greenworks G40LM41, about £269.16 and 20.8 kg, belongs only if you can lift it.

A small lawn, and the listing to treat carefully

The Swift EB122C is the pick only when the lawn is about the stated 50 m² and you do not need a box. It is about £134.99, 22 cm and 5.2 kg, at 4.5 from 330 reviews, with a super-mulch blade. The 2.0 Ah pack is the complaint. If you also want to bag the spring cut, this is the wrong fork. The Einhell GE-CM 18/33 Li is 4.3 from 7,288 reviews at about £149.95, with a 4.0 Ah pack. It is the best value full kit on price and review volume, and it is not automatically the mulching pick. The bullet calls side discharge the mulching function and says there is no bag. A highlight mentions a 30 litre box and up to 20 m², against up to 200 m². Keep both figures. One unit bought in May 2026 stopped and was refunded. The Hyundai at about £125.99 states a plug and a bag, at 3.9 from 51 reviews. It should not outrank the WG737E on price alone.

Rows that do not state mulch

If mulch is why you are here, skip three listings. The Worx WG779E at about £203.99 does not state a plug, and the width prints both 30 cm and 34 cm. The Yard Force LM G32 at about £159.99 has a rear roller and a 30 litre bag, at 4.1 from 1,707 reviews. Buy it for stripes on a short lawn. Do not buy it as a mulcher. The Litheli at about £239.99 names two 4.0 Ah batteries and does not name a charger or a mulch plug. It is 3.8 from 24 reviews. Re-check the live amazon.co.uk page. Wet grass is still the usual reason to collect.

Common questions

When is the Bosch 32 cm kit enough?
The Bosch kit is enough when one 18 V 4.0 Ah pack covers the lawn and you want a plug plus a 35 litre bag at about £181.00. A review describes about 60 m² in 20–25 minutes. It is the wrong kit if you want a second battery included, or if the grass is already long.
Why is a 7,288-review listing not automatically the pick?
The Einhell’s 4.3 from 7,288 reviews is a large sample, and about £149.95 includes a 4.0 Ah pack. The mulch wording is side discharge, and the page disagrees on the bag and on 200 m² versus 20 m². Review volume does not repair that conflict.
Who should buy the 22 cm Swift instead?
Buy the Swift if the lawn is around the stated 50 m², you can live with 5.2 kg and no bag, and you want 4.5 from 330 reviews at about £134.99. Skip it if you need to collect. The 2.0 Ah pack is the limit reviewers mention.
Which rows should you skip if mulch is the reason you are here?
Skip the WG779E, the Yard Force and the Litheli, because mulch is not stated. The Yard Force can still be a striped collector. The Litheli also leaves the charger unnamed. Side discharge on the Einhell is not the same statement as a rear plug.
Is a magazine best cordless the same mower?
Often it is not. BBC Gardeners’ World cordless round-ups have featured a self-propelled Worx Nitro that is not these ASINs. Use those pages for what a driven mower costs elsewhere. Do not copy their verdict onto the WG737E.
