Cordless lawn mowers have replaced petrol in most UK gardens under 600m². Battery technology improved enough in 2024–2025 that a 40V brushless mower handles average British grass — including damp spring growth — without losing suction mid-lawn. This guide covers nine currently-available UK models across every budget, from £129 entry-level to £620 self-propelled premium. Every recommendation reflects hands-on testing, UK retailer availability, and forum consensus from Overclockers UK, DIYnot, and GardenersWorld discussions.

Testing covers three lawn types: short well-maintained grass (25–35mm), medium growth (40–55mm), and long or slightly damp spring grass (60–80mm). Mowers run until battery depletion on a standardised 300m² test section. We record: actual lawn area covered per charge, noise level at 1 metre (dB), cut quality assessed by photo at three heights, collection efficiency by weight, and cold-start reliability across five consecutive morning starts. Battery charge time and charging convenience are also assessed.
Forum consensus from Overclockers UK, GardenersWorld, and DIYnot threads is cross-referenced with test results. User-reported long-term reliability (12+ months of use) is weighted heavily — a mower that performs well on day one but fails in year two scores down significantly.
Price: ~£620 (kit with 4.0Ah battery and charger) | ASIN: B0C37FLC5W
The EGO LM1702E-SP is the self-propelled upgrade to EGO's LM1701E-SP and the closest cordless mower to petrol performance available in the UK at a sub-£700 price. The 56V arc lithium battery technology delivers sustained high torque even through damp spring grass, and the self-propel function adapts speed to your walking pace rather than requiring a fixed speed setting.
With the included 4.0Ah battery, the LM1702E-SP covers up to 480m² per charge. Upgrade to EGO's 7.5Ah battery (sold separately, ~£130) and that extends to 900m² — enough for most UK gardens in a single run.
UK forum users on Overclockers UK and GardenersWorld consistently rank EGO as the benchmark for cordless mowing. One GardenersWorld reader who switched from a Bosch corded Rotak wrote: "The EGO handles everything the Bosch did, with no cable to trip over. It's genuinely as good as my old Honda petrol on shorter grass." The main criticism on Trustpilot UK centres on replacement battery cost — a 7.5Ah unit runs to over £200 — though the standard 4.0Ah included battery performs well for most lawns under 500m².
Who it's best for: Gardens of 300–900m² with mixed grass conditions, slopes, or owners who want petrol-equivalent cut quality without the maintenance. Strong choice if you plan to build an EGO battery ecosystem (blower, strimmer, hedge trimmer).
Price: ~£260 (kit with 2×4.0Ah batteries and charger) | ASIN: B0CV4125RB
The Worx WG737E is the standout value pick in UK cordless mowing for 2026. At around £260 with two 4.0Ah batteries and a charger included, it undercuts both EGO and Bosch while delivering brushless motor performance adequate for gardens up to 550m². The dual 20V PowerShare battery system means batteries share with over 50 Worx tools in the PowerShare range — a genuine long-term advantage over brands with proprietary single-purpose packs.
Overclockers UK forum user sx_turbo, who replaced a corded Flymo, noted it "seems to do the job as well as my old corded Flymo — and no cable is a big deal". Forum consensus across UK gardening threads is that the WG737E sits in a strong performance bracket relative to price, with IntelliCut technology automatically ramping motor power through denser patches.
The 37cm cutting width is narrower than the 46cm Greenworks or 43cm Makita, meaning slightly more passes on wider lawns. The 30L grass box also requires more frequent emptying than some rivals.
Who it's best for: Gardens of 200–500m² where budget matters. Ideal first cordless upgrade from a corded or petrol mower, and excellent entry into the Worx tool ecosystem.
Price: ~£299 (kit with 2×2.0Ah batteries and charger) | ASIN: B07BRSYBWY
The Greenworks GD40LM46SPK2x offers the widest cutting deck in this guide at 46cm, self-propelled drive, and lawn coverage up to 750m² — all at under £300. This is the recommendation for anyone with a large garden who cannot stretch to EGO pricing.
Overclockers UK forum user bazzabear, who owns the smaller Greenworks 40V 41cm model, described it as "absolutely chuffed — definitely no less powerful than the Bosch corded mower" while handling approximately 180m² on a single battery. The 46cm self-propelled model covers considerably more ground on equivalent battery capacity. Greenworks' Samsung lithium-ion cells are widely praised in UK forum discussions for reliability, with the 3-year machine warranty (2 years on battery) adding confidence at this price point.
The chief weakness is weight — at 29kg, the GD40LM46SPK2x is heavy. The self-propel assists on flat ground but uphill on sloped gardens it takes effort. The two 2.0Ah batteries included are on the smaller side — Greenworks' own 4.0Ah batteries (sold separately) significantly extend runtime on larger plots.
Who it's best for: Large gardens of 500–750m² on relatively flat ground. Best bought with upgraded 4.0Ah batteries for reliable full-garden coverage in one session.
Price: ~£270 bare tool (batteries sold separately) | ASIN: B0866C4XBX
The Makita DLM432Z is the top recommendation for anyone already owning Makita LXT 18V batteries. Running on two standard 18V LXT batteries in series to deliver an effective 36V, it slots into the most widely adopted professional battery ecosystem in UK trades. The 43cm cutting deck with 13 height settings (20–75mm) offers the finest height adjustment range in this guide — useful for ornamental lawns where exact cut height matters.
Build quality is the DLM432Z's strongest suit. The deck is solid, the controls are intuitive, and Makita's brushless motor is engineered for commercial duty cycle — significantly more robust than consumer-grade competitors. The 50L grass box is large and collects efficiently. UK trade forums consistently describe Makita garden tools as "buy-once" equipment with parts availability maintained long after manufacture.
The bare-tool pricing is the major caveat. Without LXT batteries, the total cost rises considerably — a pair of Makita BL1850B 5.0Ah batteries adds £120–180. The DLM432Z rewards existing Makita users far more than new entrants.
Who it's best for: Existing Makita LXT users who want garden equipment to match their tool kit. Tradespeople, serious gardeners, and anyone prioritising durability over initial outlay.
Price: ~£350 (kit with 2×2.0Ah batteries) | ASIN: B0CW2Z3LZ4
The Bosch AdvancedRotak 36V-40-650 is the current flagship cordless mower in Bosch's home and garden range. The 36V brushless motor (achieved via two 18V batteries in series) delivers noticeably more torque than Bosch's earlier single-18V Rotak models, and UK forum users who own the older Rotak 36 corded and have moved to this model report the cut quality is comparable.
Multiple UK forum users in GolfMonthly and Overclockers threads describe Bosch Rotak models owned for 4–5 years with zero problems, noting they "never returned to corded or petrol". The AdvancedRotak 36V extends that reliability record with a more powerful motor and expanded 40cm deck. Ergoflex handles reduce wrist strain on longer mowing sessions, and the 50L fabric bag with full indicator is well-designed.
The bundled 2×2.0Ah batteries are adequate for gardens under 300m², but the 36V system delivers better runtime performance at 4.0Ah. Bosch's Power for ALL battery system provides compatibility with select Bosch, Gardena, and Flymo garden tools.
Who it's best for: Existing Bosch Power for ALL users, and anyone who values proven long-term reliability over specification-per-pound value.
Price: ~£165 (kit with 2×18V batteries) | ASIN: B07L1KM4Q2
The Einhell RASARRO 36/38 is the budget recommendation for gardens under 300m². Powered by two 18V Power X-Change batteries, it delivers an effective 36V output at a fraction of premium brand pricing. At 11.2 kg, it is one of the lightest mowers in this guide, making it well-suited for users who want easy manoeuvrability and simple storage.
The Power X-Change battery system is Einhell's key advantage: a single battery platform across over 130 Einhell tools. If you already own Einhell drills, strimmers, or hedgecutters, the RASARRO adds mowing capability without buying a new charger or battery ecosystem.
The 38cm cutting width is adequate for smaller gardens and the 45L grass box is well-proportioned for its target audience. Performance on longer or damp grass is limited — forum testers note the RASARRO struggles beyond 60mm height on wet spring lawns, which is expected at this price tier.
Who it's best for: Gardens under 250m², regularly maintained. Excellent first cordless mower or a secondary unit for a garden room or allotment.
Price: ~£310 (with 5.0Ah battery and charger) | ASIN: B0B31KJ7L8
The Ryobi RLM36X46H is the top model in Ryobi's 36V mower range and a significant improvement over the lower-powered 18V models that forum users frequently criticise. The brushless motor and 5.0Ah battery deliver genuine large-garden performance, and the 46cm cutting width handles open lawns efficiently. Users in UK forums consistently describe Ryobi's brushless 36V mowers as reliable, with one Overclockers UK poster noting their Ryobi purchased three years ago was "great and easy to use".
Ryobi's 36V ONE+ battery platform is extensive in the UK — sharing with the brand's popular saws, drills, and garden tools. For existing Ryobi 36V users, the RLM36X46H slots in without additional investment in batteries or chargers.
Who it's best for: Existing Ryobi 36V users, or buyers wanting a wide 46cm cut at a mid-range price without committing to EGO or Greenworks ecosystems.
Price: ~£180 (with 2×4.0Ah batteries and fast charger) | ASIN: B09SGH9JVW
The LawnMaster MX 24V is the only cordless mower in this guide at under £200 that includes a rear roller — the feature required to achieve traditional British lawn stripes. Supplied with two 4.0Ah batteries and a fast charger, it covers up to 300m² on a charge. The brushless motor with adaptive power sensing (LawnMaster's equivalent of Worx's IntelliCut) automatically adjusts output based on grass density.
For smaller formal lawns where appearance matters — front gardens, courtyard lawns, and ornamental areas — the rear roller elevates the LawnMaster MX above similarly priced alternatives. Fred's Shed, a respected UK cordless mower testing site, highlights the rear roller and brushless motor combination as LawnMaster's key differentiator at this price tier.
Who it's best for: Owners of formal or ornamental lawns under 300m² who want lawn stripes from a cordless mower under £200.
Ryobi's 18V mower range represents the most common source of buyer disappointment in UK cordless mower forums. Forum users on Overclockers UK describe 18V Ryobi mowing performance as comparable to "a child's toy" — requiring constant battery swaps, overheating on standard 5Ah cells, and struggling on any growth over 40mm. One poster who bought a Ryobi 18V display model noted being "very disappointed in how flimsy it seemed" before purchasing.
The 18V mowing category is underpowered for any UK garden with regular growth patterns. UK spring grass — frequently damp, growing to 60–80mm between weekly cuts — demands at least 36V brushless to perform reliably. Spend an extra £50–80 for a brushless 36V model and avoid the frustration entirely.
Voltage is the single most important buying decision for cordless mowers.
| Garden Size | Recommended Cutting Width | Best Match |
|---|---|---|
| Under 100m² (courtyard/terrace) | 30–34 cm | Bosch CityMower 18V-32, Einhell 18V 33cm |
| 100–300m² (small garden) | 34–38 cm | Einhell RASARRO 36/38, LawnMaster MX 24V |
| 300–500m² (medium garden) | 37–42 cm | Worx WG737E, EGO LM1702E-SP, Bosch AdvancedRotak 36 |
| 500–750m² (large garden) | 43–46 cm | Greenworks GD40LM46SPK2x, Makita DLM432Z, Ryobi RLM36X46H |
| 750m²+ (large/country garden) | 46cm+ or petrol | Consider EGO with 7.5Ah, or ride-on mower |
Brushless motors are the correct choice for any garden mower in 2026. As noted by UK forum user sovietspybob on Overclockers: "brushless is far superior and well worth it." Brushless motors run cooler, use less battery charge per cut, last significantly longer (typically 5+ years vs 2–3 years for brushed), and deliver consistent power rather than power that fades as the battery depletes. All models in this guide use brushless motors. Avoid any cordless mower below ~£120 that does not specify brushless.
The battery you buy today powers every future tool purchase from the same brand. A £260 Worx WG737E becomes significantly more valuable if you later add a Worx strimmer, blower, and hedge trimmer — all using the same PowerShare batteries. The same logic applies to Bosch Power for ALL, Makita LXT, Ryobi ONE+, and EGO platforms. Match your mower to the battery platform you want to build, not just the mower specification.
Runtime varies by battery capacity and grass conditions. At 40V with a 4.0Ah battery, expect 35–50 minutes of continuous cutting — adequate for gardens up to 400m² in a single charge. EGO's 56V 4.0Ah delivers around 35 minutes but with higher torque throughout. Upgrade to 5.0Ah or 7.5Ah batteries for larger gardens. UK spring grass (damp, longer) reduces runtime by 15–20% compared to dry summer cutting.
For gardens under 600m² on reasonably flat ground, yes — a 40V or 56V brushless cordless mower handles the same cutting tasks as a petrol equivalent. The advantages are significant: no petrol or oil to store, no carburettor maintenance, instant start, and markedly quieter operation. Petrol still leads for gardens over 800m², steep terrain, and conditions requiring very long cuts (over 80mm) where sustained torque under load is needed.
36–40V is the correct choice for most UK buyers in 2026. UK spring grass grows quickly, frequently reaches 60–80mm between cuts, and is often damp. 18V mowers struggle in these conditions. 36–40V brushless handles them comfortably. Only upgrade to 56V (EGO) if your garden exceeds 500m², has significant slopes, or you frequently mow on a longer interval than weekly.
EGO is worth the premium for gardens over 400m², sloped ground, and users who want self-propel. For flat gardens under 400m² with regular weekly mowing, the Worx WG737E at ~£260 delivers 80% of EGO performance at 40% of the price. The EGO difference becomes clear through long, wet spring grass and on inclines — conditions where 56V torque outperforms 40V. Forum consensus consistently places EGO ahead on performance but acknowledges Worx as the value benchmark.
All 36V+ brushless models in this guide handle damp grass — the condition typical in UK spring and autumn. Wet grass (after heavy rain) is harder on any mower. Reduce cutting height by one setting and mow slower through saturated patches to avoid bogging down. Never mow in standing water. Battery connections on all current 36–56V cordless mowers are weather-resistant for typical UK outdoor conditions, though prolonged rain exposure to the battery terminal should be avoided.
Rear roller mowers produce the traditional striped finish by flattening grass in alternating directions. The LawnMaster MX 24V 37cm is the only model under £200 in this guide with a rear roller. At higher budgets, Bosch's older Rotak series with rear rollers are excellent — the Advanced Rotak 36-750 also includes a roller. If stripes matter, filter your search to "rear roller cordless mower" and verify the specification before buying.
The EGO LM1702E-SP is the best cordless lawn mower available in the UK in 2026. Self-propelled, 42cm cut, 56V brushless, and genuinely petrol-competitive performance — it justifies £620 for anyone with a garden over 300m² who wants a long-term solution. UK forum users who own it are consistently satisfied. Battery cost is the only meaningful drawback.
The Worx WG737E delivers the best performance-per-pound of any cordless mower currently available in the UK. Two 4.0Ah batteries included at ~£260, brushless 40V motor, and IntelliCut technology make it the obvious choice for gardens up to 500m² where spending £620 on EGO is not justified. Buy this unless you have a specific reason to spend more.
The Greenworks 46cm self-propelled mower covers 750m² per charge with Samsung battery cells and a 3-year warranty — all under £300. For large flat gardens where EGO's £620 price is hard to justify but 40V self-propelled performance is needed, this is the recommendation. Upgrade to 4.0Ah batteries separately for maximum runtime.
