What are the best lawn mowers to buy in the UK?
Our top pick for Lawn Mowers in the UK is the KraftSense 43cm Self-Propelled Cordless Lawn Mower 40V.
For UK homeowners with medium to large lawns who want to move away from a corded mower, the KraftSense 43cm Self-Propelled Cordless 40V is the top pick — self-propulsion is a genuine quality-of-life upgrade for sloped British gardens, and 40V cordless handles up to 45 minutes of continuous cutting.

The UK lawn mower market has shifted dramatically towards cordless electric models over the past five years, and for good reason. Britain's relatively compact garden sizes (the average UK garden is around 90–180 m²) sit squarely within the capability of 40V cordless mowers, which handle these areas comfortably on a single charge. 40V brushless motors now deliver cutting performance that matches petrol mowers for most UK lawns, without the maintenance burden — no oil changes, no seasonal carburettor cleaning, no fuel storage concerns. Brushless motors are the critical specification: they are quieter, last longer, and run cooler than brushed motors. Combined with dual-battery setups (increasingly common), they can handle even the largest UK suburban lawns without stopping. Cutting width is the other key variable: 32–37cm suits smaller gardens and manoeuvrability around beds; 43cm reduces passes on medium-to-large lawns. This guide covers the best cordless lawn mowers available on Amazon UK right now.
Buying guide
What should you look for in Lawn Mowers?
1Brushless vs brushed motor: Always choose brushless for a cordless lawn mower. Brushless motors are more efficient (more runtime per charge), quieter, and last significantly longer than brushed equivalents.
2Voltage and capacity: 40V with at least 4.0Ah provides adequate runtime for a typical UK garden. Dual-battery kits extend runtime to 400 m² — necessary for larger gardens.
3Cutting width: 32–33cm suits small gardens and tight spaces. 37–43cm significantly reduces mowing time on medium-to-large lawns. More than 43cm starts to feel heavy and unwieldy for most UK users.
4Cutting height range: Look for at least 5 height settings between 25mm and 65mm. UK lawns are typically cut to 30–50mm; the ability to set a taller height in autumn and spring prevents scalping.
5Mulching function: Mulching returns clippings to the lawn as fertiliser — the RHS recommends it for most UK lawns. Useful in the fast-growing UK spring and summer, though you will need the grass box for autumn leaf cleanup.
Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise the strongest independent evidence — current Amazon UK listings, verified-buyer feedback, published specs and UK pricing — into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We only shortlist products actively listed and in stock on Amazon UK, checked against live catalogue data — not last year’s models.
Publicly visible buyer feedback
We look at how each product is received by UK shoppers — its overall rating standing and the praise or complaints that recur in public reviews — rather than relying on a single reviewer’s opinion.
Published specs & value
We compare manufacturer specifications, typical UK price bands, warranty and running costs so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage, plug/fitting standards, CE/UKCA marking and Consumer Rights Act cover — details that generic global lists miss.
The KraftSense is the top pick for medium-to-large UK gardens with slopes or thick grass. The self-propelled drive removes most of the physical effort from mowing, and the dual 5.0Ah batteries give the highest total runtime in this guide. The Z-fold storage design is a genuinely practical feature for UK garden sheds where space is always at a premium.
The NETTA 43cm is the best choice for larger UK gardens where mowing time matters. The dual fast-charger means both batteries can charge simultaneously, effectively halving your waiting time between sessions. The 50L grass box with fill indicator is a practical touch that prevents the overflowing box problem that interrupts many mowing sessions.

–14 kg weight is heavier than smaller-width alternatives
The NETTA 37cm is the better choice for average UK semi-detached gardens where manoeuvrability around borders and raised beds matters more than sheer speed. The smaller width and lighter weight make it meaningfully easier to handle, particularly on UK lawns with tight corners and ornamental features.

Yard Force 40V Cordless Lawn Mower 32cm with Rear Roller
The Yard Force is the only mower in this guide with a rear roller — a feature prized by UK gardeners who want classic striped lawn patterns. The 32cm cutting width makes it exceptionally manoeuvrable around trees and borders in small UK gardens. If lawn aesthetics matter as much as efficiency, this is the pick.

The VonHaus 40V is a reliable choice for smaller UK gardens up to around 150 m². The 25-minute runtime suits a typical terrace or semi-detached back garden in a single session. The mulching feature is a useful bonus and the VonHaus brand's UK customer support record is strong.

–Single battery included; no dual-battery option at this price
The Ryobi OLM1833B makes sense almost exclusively for existing Ryobi ONE+ users who already own compatible batteries. For them, it is excellent value — the lightest mower in this guide with a useful edge comb feature. For those starting fresh, the 40V options above offer better performance and included batteries.

What we like
+Part of Ryobi ONE+ ecosystem — battery shares with 100+ other Ryobi tools
+Lightest mower in this guide at 7.7 kg (without battery)
+Edge grass comb mows right to the perimeter without a separate trimmer
Worth noting
–Battery not included — additional cost if you don't already own Ryobi ONE+
–18V delivers less torque than 40V models on thick UK summer grass
UK lawn care follows a predictable seasonal rhythm that should influence your mower choice. From March to May, grass grows fastest — you may need to mow twice a week — so runtime and cutting width matter most. From June to August, growth slows; once per week at 35–50mm is standard. September and October see another growth surge before winter dormancy. Most cordless mowers perform better cutting little and often rather than tackling long, overgrown grass in a single session — this is especially true in the UK's wet climate where grass can be dense and damp. For UK lawns with clay-heavy soil (common in much of the South East and Midlands), keeping the grass at 40–50mm height provides better drought resistance in dry summers and reduces the risk of scalping on the slightly uneven ground that clay creates.
Our Take
UK weather is unpredictable — garden tools and furniture need to survive rain, frost, and the occasional heatwave. The KraftSense 43cm Self-Propelled Cordless Lawn Mower 40V is our top recommendation. If that's out of budget, the Ryobi 18V ONE+ 33cm Cordless Lawn Mower offers solid performance at a lower price point. The NETTA 43cm Cordless Lawnmower 40V is worth considering if you want a step up in build quality or features. Avoid the cheapest unbranded options on Amazon UK — they rarely survive past six months of regular use and UK consumer protection only helps if the seller is still trading.
Questions & answers
Frequently asked questions
Is a cordless lawn mower powerful enough for a UK garden?
Yes, for the vast majority of UK gardens. A 40V brushless cordless mower provides cutting performance comparable to petrol mowers on lawns up to 400 m². The typical UK semi-detached garden is 90–180 m², well within the capability of a single battery charge. Where cordless falls short is on very thick, overgrown grass — in those cases, a single pre-pass with a petrol strimmer before mowing helps.
How often should I mow my lawn in the UK?
For a well-kept UK lawn, mow every 7–10 days from March to October, reducing to once per fortnight in mild winters. In the peak UK growing season (April–June), twice weekly at 30–40mm produces the best results. Never remove more than one-third of the grass blade length in a single mow — cutting too short stresses UK lawns and encourages moss and weed growth in the damp climate.
What cutting height should I set my lawn mower for a UK lawn?
For a standard UK decorative lawn, 25–40mm in summer is ideal. In spring and autumn, cut at 40–50mm to allow the grass to photosynthesise more effectively and build root strength before winter. Avoid cutting below 20mm in the UK climate — this scalps the lawn and creates bare patches that are vulnerable to moss invasion, particularly in the shaded conditions typical of UK north-facing gardens.
