Product Reviews
1. Worx WG779E.2 40V
Best for: Tight budgets and small-to-medium gardens
Key specs: 34cm cutting width, 40V lithium-ion (PowerShare, 2x 2.0Ah batteries and charger included), 6 cutting heights (20–70mm), 30L grass bag, 30–45 min runtime, 15kg, rated for gardens up to around 230m²
Pros: Excellent value at time of writing, PowerShare battery compatibility with other Worx 20V/40V tools, lightweight, foldable for storage, quiet operation
Cons: Batteries drain quickly in thick or long grass, best suited to lawns under 250m², no self-propulsion, modest bag capacity
The WG779E.2 remains the mower we point budget-conscious readers to first. It ships as a complete kit — two 2.0Ah batteries and a charger included — so there’s nothing extra to buy before you can start mowing, and the PowerShare system means those batteries also work across Worx’s wider 20V/40V garden tool range.
2. Greenworks GD24LM33K4 24V
Best for: Apartment dwellers and compact gardens
Key specs: 33cm cutting width, 24V lithium-ion (4.0Ah battery and charger included), 5-level cutting height adjustment, 30L mulching bag, rated for gardens up to around 300m², compact folding design
Pros: Strong affordability at time of writing, lightweight and easy to manoeuvre, quiet operation, compact for storage, largely maintenance-free
Cons: Entry-level 24V power output, shorter runtime than 36V+ machines, can struggle in thick or overgrown grass, no self-propulsion
Greenworks’ GD24LM33K4 kit is the current UK-market version of this entry-level 24V mower, and it’s the one we’d point smaller-garden owners towards — it comes bundled with a 4.0Ah battery and charger rather than sold bare, which keeps upfront cost and hassle down. Our EGO vs Greenworks comparison looks at the two platforms side by side.
3. Bosch AdvancedRotak 36V-44-750
Best for: Mid-sized gardens and consistent cutting quality
Key specs: 44cm cutting width, 36V lithium-ion (battery and charger sold separately), 6 cutting heights (20–70mm), 50L bag, 30–50 min runtime depending on battery size, 23kg, rated for lawns up to roughly 600–750m² depending on battery capacity
Pros: Professional-feeling cutting quality, 44cm deck is efficient for mid-to-large plots, anti-vibration handle, brushless motor, compatible with the wider Bosch 36V tool ecosystem, runtime extends well beyond 50 minutes with a larger battery fitted
Cons: Not self-propelled, battery and charger sold separately (factor this into your budget), heavier than the budget options here, coverage per charge depends heavily on grass thickness and battery size
This is the mower we keep recommending as the best all-rounder for a typical UK garden. It’s sold as a bare tool — no battery or charger in the box — so you’ll want to budget for at least one 36V Bosch battery, but that also means you can reuse existing Bosch Home & Garden batteries if you already own them, or scale up to a bigger pack for longer runtime.
4. Makita DLM432Z Twin 18V LXT
Best for: Larger lawns and serious gardeners valuing durability For really big lawns, consider a robotic mower or a ride-on.
Key specs: 43cm cutting width, dual 18V LXT (36V equivalent, batteries and charger sold separately), 13 cutting heights (20–75mm), 40L bag with grass-level indicator, 45–90 min runtime, 15.8kg body weight, three-in-one cutting/collecting/mulching function
Pros: Exceptional build quality and durability, twin 18V system lets you swap in a second pair of batteries for continuous mowing, strong cutting power through thick grass, wide 13-position height adjustment, LXT battery compatibility with hundreds of other Makita tools
Cons: Sold as a bare tool — batteries and charger add a further £100–£250 depending on the kit you choose, heavier than the lighter budget mowers here, twin-battery management has a small learning curve, no self-propulsion
The DLM432Z is still our pick for anyone with a genuinely large lawn who already has (or is willing to invest in) the Makita 18V LXT battery ecosystem. Buying it body-only keeps the base price down, and if you’ve already got LXT batteries from other Makita tools, this is one of the cheapest ways into a serious cordless mower.

5. Ego LM1702E-SP 56V Self-Propelled
Best for: Premium gardens and users wanting effortless mowing
Key specs: 42cm cutting width, 56V lithium-ion (4.0Ah battery and standard charger included), 6 adjustable cutting heights, self-propelled variable-speed wheel drive, poly deck, 5-year tool warranty and 10-year battery warranty
Pros: Self-propulsion removes almost all the physical effort of mowing, 56V power feels petrol-equivalent and handles dense, overgrown grass with ease, premium build quality, quiet for a machine this powerful, industry-leading warranty cover
Cons: Premium pricing at time of writing, heavier than push mowers due to the motor and drivetrain, still needs manual steering on turns, overkill for gardens under 150m²
If budget isn’t the deciding factor, the LM1702E-SP is still the mower to beat. It’s sold as a complete kit with a 4.0Ah battery and charger included, so there’s no extra outlay before you can start mowing, and the self-propelled drive makes it genuinely effortless on larger or sloped lawns.
Buying Guide
What to Look For
Cutting Width: 34cm for gardens under 200m²; 40–44cm for 300–600m²; 46cm+ for lawns exceeding 600m². Wider decks reduce the number of passes needed but add weight.
Battery Voltage & Capacity: Entry-level 24V systems typically offer 20–30 minute runtimes; 36–40V systems usually deliver 40–50 minutes; premium 56V systems can exceed 60 minutes. Higher amp-hour batteries extend runtime roughly proportionally.
Runtime Requirements: As a rough guide, a 34cm mower covers 150–200m² per hour, a 40cm mower covers 200–250m², and a 44cm mower covers 250–300m². Apply roughly a 1.5x time factor for thick or overgrown grass.
Self-Propulsion: Transforms the experience on slopes, larger gardens, or where physical effort is a concern, though it adds weight and cost.
Battery Ecosystem: Where possible, choose a mower brand that matches your existing cordless garden tools — it lets you share batteries and chargers and reduces your overall investment.
Cutting Height Adjustment: More positions (6–13) suit gardens with varied grass types; a single-lever adjustment mechanism is the most convenient in practice.
Types of Cordless Mowers
Push Mowers: Entry-level, lightweight and affordable; you supply the pushing force; best for small-to-medium gardens and budget-conscious buyers.
Self-Propelled Mowers: Feature wheel drive that powers the mower forward; you steer and control the speed; a clear step up for larger gardens, slopes, and anyone wanting to reduce physical effort.
Robotic Mowers: Not covered in depth here, but worth a mention — fully autonomous, scheduled mowing is available at a premium price, and can be a genuinely transformative option for the right garden.
Spending Guidelines
- Budget: Entry-level 24–40V push mowers, best suited to gardens under around 250m², with runtimes of roughly 20–45 minutes.
- Mid-Range: Quality 36–40V systems suited to 300–600m² gardens, with consistent performance and broader battery-ecosystem compatibility.
- Premium: Powerful 56V self-propelled systems suited to gardens exceeding 600m², minimal physical effort required, and comprehensive warranty cover.
Budget for additional costs too — spare batteries typically add £80–£150 each, and premium high-capacity batteries (5.0Ah+) can cost £100–£180 each.
FAQ
How long do cordless lawnmower batteries last?
Modern lithium-ion batteries typically retain 70–80% of their capacity after 5–7 years of regular use. Premium systems like Ego’s come with ten-year battery warranties. Most batteries handle 500–1,000 full charge cycles before noticeable degradation sets in. Storing batteries somewhere cool and dry, with a partial charge over winter, helps extend their working life.
Can I use one battery across multiple tools?
Yes, within the same brand’s ecosystem. Bosch 36V tools share batteries across the range; Makita’s LXT 18V system works across hundreds of tools; Ego’s 56V batteries work across their entire Power+ range. This cross-compatibility is one of the best reasons to stick with a single battery ecosystem as you build up your tool collection.
Is cordless power sufficient for thick or overgrown grass?
Budget 24V models can struggle; 36–40V systems manage most typical UK garden conditions; 56V premium systems match petrol-equivalent power. For genuinely overgrown grass (10cm or more), it’s worth running a strimmer over it first.
What battery capacity suits my garden size?
Under 300m²: a single 2.0–4.0Ah battery is usually enough. 300–500m²: look at a dual 4.0Ah setup or a single 6.0Ah battery. Over 500m²: consider multiple 5.0Ah+ batteries or a self-propelled system built around larger packs. If you mow twice a week, a spare battery is a sensible investment.
Final Verdict
For most UK gardeners with an average-sized lawn, the Bosch AdvancedRotak 36V-44-750 still offers the best balance of performance, reliability and value — just remember to budget for a battery and charger, since it’s sold as a bare tool. If your garden is larger, sloped, or you simply want the least physically demanding mow possible, the Ego LM1702E-SP self-propelled system is worth the extra investment.
