In-Depth Reviews
1. Bosch ROTAK18V-32 Cordless Lawn Mower
~Β£185.00 | Cutting width: 32cm cutting width | Small to medium lawns
The Bosch ROTAK18V-32 is the cordless lawn mower that keeps popping up in UK garden sheds for good reason. It's light enough to carry one-handed (just 13kg with battery), starts instantly at the press of a button, and delivers a clean, even cut across small to medium lawns up to about 300mΒ².
"I bought this after my old Flymo finally gave up. It's noticeably lighter and the battery lasts long enough to do my 80mΒ² front and back lawn on one charge," reports one Verified Amazon purchaser. Another says: "The mulch plug is brilliant β no more emptying the grass box mid-mow. My lawn looks greener since I started mulching."
Where it falls short: the 32cm cutting width means more passes on larger lawns, and taller grass can bog it down if you let things get overgrown. But for weekly cuts on a typical UK semi-detached garden, it's near-perfect.
β Pros
- β Lightweight and easy to manoeuvre
- β Battery and charger included
- β Mulch plug for grass recycling
- β Easy fold-flat storage
β Cons
- β 32cm deck is narrow for larger lawns
- β Struggles with very long/overgrown grass
- β Grass bag could be bigger
2. Flymo Speedi-Mo 360VC Electric Rotary Mower
~Β£110.00 | Cutting width: 36cm cutting width | Value and reliability
Flymo's Speedi-Mo 360VC has been a British garden staple for years, and the current model keeps the formula that works β 1500W of reliable cutting power, a generous 40L grass box, and a price that won't make your eyes water. It's a simple, no-nonsense electric rotary mower for anyone with a lawn under 200mΒ².
"Bought this to replace a 15-year-old Flymo. Same great cut, modern design, still takes up hardly any shed space," says a long-term customer. Another reviewer notes: "The 1500W motor doesn't flinch on slightly damp grass β my old mower would clog constantly."
The trade-offs are minimal: you're tethered to a mains cable (so factor in a good extension lead), and the cutting height adjustment is a manual lever rather than the tool-free systems on pricier mowers. But at this price, you're getting brilliant value for money.
β Pros
- β Very affordable for an electric mower
- β 1500W motor handles damp grass well
- β Large 40L grass box
- β Folds flat for easy storage
β Cons
- β Requires mains power cable
- β No mulch function
- β Plastic deck less durable than steel
3. Greenworks 40V Cordless Mower (41cm)
~Β£259.99 | Cutting width: 41cm cutting width | Medium to large lawns
If your lawn tips into 'proper job' territory β say 200-500mΒ² β the Greenworks 40V 41cm mower is where cordless gets serious. With a 41cm cutting deck and two 40V batteries in the box, it'll tackle the average British garden on a single charge, with a spare ready to go for the next session.
"I can do my entire lawn (roughly 300mΒ²) on one battery and still have plenty of charge left," shares an Amazon reviewer. "The 50L grass bag is massive β I can finish the whole garden without emptying once."
The 40V system gives noticeably more torque than 18V rivals, which means it handles thicker grass and slightly overgrown lawns without the blade slowing down. The steel cutting deck adds durability, though it does make the mower heavier than the Bosch. If you've got a larger lawn and don't want petrol, this is the sweet spot.
β Pros
- β Excellent battery life (2 included)
- β 41cm deck covers ground quickly
- β 50L large grass collection bag
- β Steel deck for durability
β Cons
- β Heavier than 18V models
- β No self-propel option
- β Battery charger is basic
4. Hyundai 196cc Petrol Self-Propelled Mower
~Β£350 | Cutting width: 51cm cutting width | Large lawns (500mΒ²+)
For the big lawns β think 500mΒ² and above β a petrol self-propelled mower is the only sensible choice. Hyundai's 196cc model brings proper grunt with a 51cm cutting deck that chews through grass without breaking a sweat. The self-propel drive means you're guiding, not pushing, which makes a huge difference over a long afternoon.
"This mower is a beast. My lawn is roughly 600mΒ² and it cuts through the whole thing in about 40 minutes without a single complaint," reports an Amazon reviewer. Another says: "The 70L collector is enormous β I can do the entire front lawn without stopping to empty it."
Downsides: it's heavy (around 30kg), requires petrol and oil maintenance, and is louder than electric alternatives. But nothing else delivers this speed and power for larger UK lawns. If you've got a big garden and want the job done fast, this is your mower.
β Pros
- β Powerful 196cc engine
- β Self-propelled β saves effort on slopes
- β 51cm wide cutting deck
- β Huge 70L grass bag
β Cons
- β Heavy and needs storage space
- β Regular maintenance (oil, fuel, spark plug)
- β Louder than electric mowers
- β Emissions from petrol engine
5. Ryobi 18V ONE+ OLM1833B Cordless Mower
~Β£130 (tool only) | Cutting width: 33cm cutting width | Small gardens & ONE+ ecosystem users
If you're already invested in Ryobi's ONE+ battery system (and who isn't β there are over 200 tools in the range), the OLM1833B is a no-brainer. It's compact, lightweight, and shares batteries with your strimmer, hedge trimmer, and drill. For small lawns under 150mΒ², it's surprisingly capable.
"Perfect little mower for my tiny London garden. I already had the batteries from my Ryobi strimmer so this was a cheap add-on," says one happy customer. Another notes: "The EasyEdge combs let me cut right up to the lawn edge β no need for separate edging shears."
The main limitation is the 33cm width β it's narrow, so larger lawns mean many more passes. And it doesn't come with a battery or charger, so factor in that cost if you're new to the ONE+ ecosystem. But for small gardens with existing Ryobi gear, it's excellent value.
β Pros
- β Shares Ryobi ONE+ battery platform
- β Very lightweight (under 10kg)
- β Edge trimming combs included
- β 5-position height adjustment
β Cons
- β Narrow 33cm deck
- β Battery and charger sold separately
- β Not for lawns over 150mΒ²
- β Plastic deck feels less robust
6. LawnMaster OcuMow Robot Lawn Mower
~Β£299.00 | Cutting width: No boundary wire needed | Set-and-forget convenience
Robot mowers have traditionally been the preserve of tech enthusiasts willing to bury boundary wires around their lawn. The LawnMaster OcuMow changes that with camera-based navigation that maps your garden without any wires at all. Drop it on the lawn, pair it with the app, and let it do the work.
"I was sceptical about a robot mower but the OcuMow is genuinely brilliant. It navigates around my flower beds and trees without getting stuck," marvels an Amazon reviewer. The 24V battery handles up to 150mΒ², returning to its charging dock automatically when juice runs low.
The trade-off: at Β£500 it's a significant investment, the 150mΒ² limit means bigger gardens need multiple units, and the cutting quality doesn't quite match a traditional mower's striped finish. But for the convenience of a perfectly maintained lawn without lifting a finger, early adopters are loving it.
β Pros
- β No boundary wire installation
- β Automated mowing schedule via app
- β Returns to charger automatically
- β Quiet operation
β Cons
- β Β£500 is a big investment
- β Limited to 150mΒ² lawns
- β Cut quality not as good as manual mowers
- β Camera-based nav can struggle in low light
How to Choose the Right Lawn Mower for Your UK Garden
With so many options on the market, choosing the right mower comes down to three things: your lawn size, your storage space, and your willingness to perform maintenance.
Lawn Size
This is the single biggest factor. For lawns under 200mΒ², a cordless electric mower like the Bosch ROTAK18V-32 or the Ryobi OLM1833B (if you're already in the ONE+ ecosystem) will be perfect. Between 200-500mΒ², step up to high-capacity cordless models like the Greenworks 40V 41cm with its twin batteries. Over 500mΒ², it's time to seriously consider petrol self-propelled mowers like the Hyundai 196cc.
Corded vs Cordless vs Petrol
Corded electric mowers like the Flymo Speedi-Mo are the cheapest option with unlimited runtime, but you're tied to a mains socket. Cordless offers freedom of movement with the convenience of push-button starting β just keep an eye on battery life. Petrol delivers the most power and runtime but requires regular maintenance (oil changes, spark plugs, fuel stabiliser) and is significantly louder.
Storage
Most modern mowers fold flat for vertical storage, but check the dimensions. The Bosch and Ryobi cordless models are the most compact, while the Hyundai petrol mower needs proper garage or shed space.
Special Features
Look for mulching capability (returns finely chopped grass to the lawn as fertiliser), adjustable cutting heights, and grass bag capacity. If convenience is your priority, robot mowers like the LawnMaster OcuMow are becoming increasingly capable and don't even need boundary wires.
Frequently Asked Questions
Final Verdict
For the vast majority of UK gardens, the Bosch ROTAK18V-32 is the lawn mower we recommend most often. It strikes the perfect balance of weight, power, battery life, and build quality for small-to-medium British lawns β all at a price that won't break the bank.
If you're on a tighter budget, the Flymo Speedi-Mo 360VC is a superb value corded mower that's been a British garden staple for good reason. And if you've got a bigger patch of grass to manage, the Hyundai 196cc petrol will save you hours over the growing season.
Whichever you choose, a good lawn mower is an investment in your garden that pays back every single cut. Read our Summer Lawn Care Guide for tips on keeping your lawn in top shape all season long.
