What we loved
- The weight — at 15.4 kg with battery in, this is one of the lightest cordless mowers we\'ve tested. Carrying it over a 20 cm garden step is genuinely easy.
- The stripes — Gtech\'s rear comb design shouldn\'t produce stripes as well as it does. On our 200 m² semi test lawn, the cut is visibly directional.
- The British design feel — there\'s a friendliness to the way the handle folds, the way the battery clicks in, the cut-height lever. None of it is revolutionary; all of it is nicer than the rivals.
- Battery life is honest — Gtech claim 40 minutes, we measured 36–42 across 30 mowing sessions on dry grass. Holds up.
What we didn\'t love
- No mulching plug in the box — at £249 this is annoying. Plug is £19.99 extra.
- Proprietary battery — fits only other Gtech outdoor tools. If you want shared batteries with your drill, Ryobi or Bosch make more sense.
- 33 cm deck is small — fine for under-300 m² lawns, slow on bigger ones.
- Replacement battery cost — £80–£100 in 6–8 years. Not catastrophic, but Bosch Power for All packs are around £60.
How it compares
The most direct rival is the Bosch UniversalRotak 36-550 at £329. Bosch wins on grass-box size (50 L vs 30 L), 36V Power for All shared battery system, and lawns over 300 m². Gtech wins on weight, ergonomics and the friendlier user experience. The Ryobi RY18LMX40A at £269 is the value pick if you already own ONE+ batteries — bigger deck (40 cm), much wider tool ecosystem, but heavier and less polished.
Who should buy it
First-time cordless mower buyers with a small UK lawn (under 250 m²) who want a friendly, light, no-fuss mower with stripes. Anyone older or with back/arthritis trouble who finds heavier mowers tiring. Anyone who values build refinement over cross-tool compatibility.
Don\'t buy it if your lawn is over 350 m², if you already own Bosch / Ryobi / DeWalt batteries, or if you\'re building a complete cordless garden tool kit from scratch — in those cases the Bosch UniversalRotak or Ryobi 36V MAX are better-positioned.
Where to buy
The Gtech CLM 2.0 is sold mainly direct through gtech.co.uk and on Amazon UK. Pricing is consistent across both — Gtech direct often includes free delivery; Amazon often ships faster. We monitor both and update this review when there\'s a deal worth knowing about.
What real owners say
We trawled r/GardeningUK and r/lawncare for real owner opinions on the Gtech CLM and cordless mowers in this price bracket. Here\'s what keeps coming up.
"My parents have (I think) a GTech which has been going the last couple of years (at least) and manages their lawn really well on one charge (~15m x 20m)."
— u/knotmidgelet, r/GardeningUK
"They are much better than you\'d think. I bought the smallest Husqvarna last year and it\'s a monster for cutting through stuff. Only downside is the grass box is a bit small. Battery can also be used in strimmers, hedgecutters, blowers etc."
— u/UsefulAd8513on cordless mowers generally, r/GardeningUK
"After my petrol died and wouldn\'t start / stay started despite stripping it back and cleaning it out, I went electric. I\'d never go back to petrol. They\'re so convenient!"
— u/pspspsreddit, r/GardeningUK
"Swapped from self-propelled petrol to cordless last year and love it. It\'s so much lighter that I don\'t miss the self-propelling. No servicing, filling petrol cans, troubleshooting starting problems... just charge and go."
— u/GnirobSW, r/GardeningUK
The pattern across UK Reddit threads: people switching from petrol to cordless almost universally don\'t go back. The Gtech specifically gets praised for being light and easy — the battery ecosystem lock-in is the consistent caveat, which matches our review.
