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.

Frequently asked questions

Is the Gtech CLM worth £249?+
For a small UK garden under 250 m², where you want a friendly, light, easy-to-use mower with sharp stripes, yes — it's probably the most pleasant cordless mower you can buy at the price. For bigger lawns or anyone planning to build a multi-tool battery setup (drill, hedge trimmer, blower) the rivals from Bosch or Ryobi make more sense because the Gtech battery only fits other Gtech tools.
How long does the Gtech CLM battery last?+
On a typical 200 m² UK lawn: 30–40 minutes runtime per charge from full. Charge time is about 4 hours. The battery is rated for around 1,000 cycles which works out to 6–8 years of typical UK use. Replacement is around £80–£100.
Does the Gtech CLM leave stripes?+
Yes — surprisingly well, given it doesn't use a traditional rear roller. The "rear comb" arrangement produces visible stripes on most British lawns. Not as sharp as a Hayter Harrier or Mountfield Princess with a true roller, but visibly there.
Gtech CLM vs Bosch UniversalRotak 36-550?+
Bosch wins on grass-box size (50 L vs 30 L), shared battery platform (Power for All works across Bosch garden + DIY tools), and lawns over 300 m². Gtech wins on weight, ergonomics, and the friendlier user experience for first-time cordless buyers. For most small-garden UK households the Gtech is the more pleasant mower; for medium gardens the Bosch is the more capable one.
What's included with the Gtech CLM 2.0?+
Mower, one 36V battery, charger, grass collection box. Mulching plug is sold separately for £19.99 — annoying at this price point.
