At a glance
Cordless lawn mowers have genuinely replaced petrol for the majority of UK gardens. Five years ago the honest answer to “should I buy a cordless mower?” was “only if your garden is small and flat.” In 2026 that answer has changed entirely: the best cordless platforms now deliver performance that matches or exceeds entry-level petrol mowers without the noise, fumes, annual servicing costs or fuel storage headache. For any lawn under 400m2 on reasonably flat ground, cordless is now the default recommendation without qualification.
We tested five of the most popular cordless mowers currently available in the UK – putting each through typical British garden conditions including long wet grass after a week of rain, the hardest real-world test any UK mower faces. The five cover a price range from around £130 to £449 and represent the most useful spread of performance levels for UK buyers in 2026.
How we tested. Each mower was used on the same lawn over multiple cuts across different conditions – freshly mowed weekly grass, 10-day growth and post-rain long grass. We scored each on cut finish, battery life under load, ease of use, manoeuvrability and value for money in UK conditions.
Quick verdict summary
All 5 cordless mowers ranked
The EGO LM1903E is the cordless mower we would recommend to most UK homeowners with a medium to large garden. The 56V 5Ah battery delivers genuine petrol-mower performance without the noise, fumes or annual servicing. On a typical UK semi-detached garden of 150-200m2 it handles a full cut with battery to spare, even in the long wet grass that accumulates after a week of British weather. The self-propelled drive makes light work of any slopes and the rear roller produces clean traditional stripes.
At £449 it is the most expensive in our test, but for a tool used weekly for a decade the cost-per-cut calculation is favourable. The 56V platform is compatible across the full EGO range including blowers, trimmers and hedgetrimmers – a meaningful benefit for anyone building an EGO toolkit. The 55-litre grass box is generous and the weather-sealing is noticeably more comprehensive than any of the cheaper options we tested.
The Bosch AdvancedRotak 36-660 sits in the sweet spot for most UK gardens: enough performance for lawns up to 250m2, a 36V platform available with various battery capacities, and a price substantially lower than the EGO. The 44cm cutting width covers ground efficiently, the collection system works well in both dry and damp conditions, and height adjustment is quick and precise across seven positions from 20-70mm.
In our wet grass test it handled moderately long growth without bogging down, though it required a slightly slower pace than the EGO. The 36V platform is shared across Bosch’s broader garden tool range including their cordless trimmers and blowers, which adds value for anyone already invested in the Bosch ecosystem. For most suburban gardens it represents excellent value and is the mower we would recommend if the EGO’s price is out of reach.
The Greenworks GD48LM41 punches above its price point with a 41cm cutting width on a 48V platform – a wider deck than you would typically expect at this price level. For gardens up to around 180m2 in good condition it performs reliably, and the build quality feels more solid than the price suggests. The grass box is a reasonable size at 45 litres and empties cleanly without jamming.
Where it shows its limitations is in demanding conditions – long wet grass slows it noticeably and the motor works harder than the premium options. Runtime on the included 2Ah battery is sufficient for a 100-150m2 lawn at one mowing but tight for larger areas. Buying a spare battery for £40-50 largely solves the runtime issue and makes this a strong choice at the price.
The Worx WG779E is a compact, lightweight mower well matched to small urban gardens up to around 100m2. It is noticeably lighter than the other mowers in our test which makes it easy to manoeuvre in tight spaces and around obstacles, and the 40V platform is shared with other Worx garden tools. The 34cm cutting width means more passes on a larger lawn but is perfectly scaled to a compact garden with regular mowing.
Performance on normal weekly-mowed grass is solid but it struggles in longer growth – reducing forward speed is needed to avoid stalling in anything over two weeks’ growth after a wet spell. The grass box at 35 litres fills quickly on a long-grass cut. For its intended use case – a compact garden mowed weekly – it does the job without complaint and the price is genuinely competitive.
The Flymo EasiMow 300R is a corded rotary mower included here as the most affordable option for anyone wanting a reliable basic mow on a small, flat garden. At around £130 it is significantly cheaper than any of the cordless options, but the trade-off is a mains cable – practical on a small, simply shaped garden close to a socket, genuinely limiting on anything larger or more complex.
The 30cm cutting width suits gardens up to 60-80m2, and on that scale it cuts efficiently with zero battery management overhead. Build quality is basic – the chassis is lightweight plastic and the grass box holds just 30 litres – but cutting performance on normal grass is perfectly adequate for its intended use. It is not a mower for anyone with a garden of meaningful size, but as an entry-level option for a compact urban garden it does exactly what it promises.
Head to head comparison
What to look for when buying
The single most important question when choosing a cordless mower is lawn size. Runtime on a single battery determines how much lawn you can cut per charge, and this varies enormously between models. As a rough guide: a 2Ah battery on a compact mower covers 80-120m2, a 4Ah battery on a mid-range model covers 150-200m2, and a 5Ah or 7.5Ah battery on a premium mower covers 250-400m2. If your garden is at or near the limit of a single charge, either buy a second battery or choose the next model up.
Cutting width is the other key specification. A wider deck covers more ground per pass and finishes the job faster, but a wider mower is harder to manoeuvre in tight spaces, heavier to lift over steps, and may not fit through a standard garden gate. Measure your narrowest access point before specifying a deck width – a mower that cannot reach the lawn is useless regardless of its performance rating.
Self-propulsion is genuinely worth the premium for anyone with a large lawn or any significant slope. A self-propelled mower drives its rear wheels from the motor, taking the effort of pushing entirely out of the equation and making mowing much less physically demanding over 200m2 or more. The EGO LM1903E is the only self-propelled model in our test and the difference is immediately noticeable on even a gentle gradient. Rear rollers – also exclusive to the EGO in this test – produce the light-and-dark lawn stripes that many UK gardeners value and are worth seeking out if appearance matters.
Battery platform compatibility matters more than it seems. Before buying any cordless mower, check whether it shares a battery platform with tools you already own. Compatible batteries from the same brand can be used across the full range of tools, which means a spare battery for the mower also serves as extended runtime for a leaf blower or trimmer. An incompatible platform means buying new batteries for every tool.
Final verdict
For most UK homeowners with a garden of 100-300m2, the Bosch AdvancedRotak 36-660 is the mower we would recommend first. It delivers reliable performance in typical British conditions, covers a sensible area per charge, and costs substantially less than the EGO without a meaningful performance gap for average weekly mowing on normal grass. It is the mower that best balances performance, practicality and price for the majority of UK gardens.
For larger gardens, anyone who mows less frequently and encounters longer grass, or anyone who simply wants the best tool available without compromise, the EGO LM1903E is the clear choice. The self-propulsion, larger cutting width, more powerful motor and bigger battery capacity justify the premium for regular use on a larger lawn. Nothing in this test comes close for performance on a garden over 200m2.
At the budget end, the Greenworks GD48LM41 offers a wide cut at a competitive price with the caveat of limited included battery runtime. The Worx WG779E handles small gardens well at its price point. The Flymo EasiMow 300R remains the right choice only where budget is the absolute priority and the limitation of a cable is acceptable.
Best overall: EGO Power+ LM1903E. Self-propelled, rear roller, 56V platform, 48cm cut. Nothing else in this test matches it for larger lawns.
Best value: Bosch AdvancedRotak 36-660. Excellent for gardens up to 250m2 at £200 less than the EGO.
Best budget: Worx WG779E. Lightweight and capable for small urban gardens mowed weekly.
The EGO LM1903E is the best cordless lawn mower available in the UK for most gardens with the budget to match. For everyone else, the Bosch AdvancedRotak 36-660 is the mower we would actually buy – it handles most UK gardens without compromise and leaves £200 in your pocket.
