Best Cordless Lawn Mowers for Small Gardens UK 2026
For a small British garden - a courtyard, a front lawn, a back patch under about 200 m² - you do not need a big, heavy mower, and you certainly do not need petrol. What you want is light, compact, easy to store, and an 18V battery that cuts cleanly and tucks the mower away flat when you are done. These four cordless mowers fit a small space without taking it over.
Why a compact mower is the right call for a small garden
The mistake people make with a small lawn is buying too much mower. A 40 cm deck and a twin-battery system are wasted on 150 m²: you carry the extra weight every week, you fight to turn it around a flower bed, and you give up half your shed to store it. The whole point of a small-garden mower is that it disappears when you are not using it. Light enough to lift over the back step one-handed, a 30-34 cm deck that turns on a sixpence around borders, and a body that folds flat against a wall or onto a shelf.
On a lawn this size, an 18V battery is not a compromise - it is the right amount of power. Higher voltages exist to deliver torque for long, wet grass on bigger lawns. A small lawn that you cut weekly stays short, and 18V cuts it cleanly with charge to spare. Spending up for 36V or 40V on a tiny garden mostly buys you weight you do not want.
The best cordless mowers for small gardens
Four mowers we are happy to recommend for a small UK lawn, ordered by who each one suits best. Tap any pick to read the full review.
Bosch CityMower 18V-32
Bosch
For a courtyard, front lawn or a back garden under about 200 m², the CityMower is the one we point most people to. It weighs next to nothing, folds flat against a wall, and the 32 cm deck is the right size for a small space without being slow. Manufacturer runtime on a 4.0 Ah pack covers a typical 150-200 m² lawn on a single charge, and because it sits on Bosch Power for All the battery doubles up across the rest of your garden kit.
Pros
- + Just 8-9 kg - genuinely carry it one-handed
- + 32 cm deck folds flat for shed or cupboard storage
- + Runs on Bosch 18V Power for All - shares with strimmer and blower
Cons
- − 31 L grass box fills quickly on longer grass
- − Single 18V battery, so not for lawns much past 200 m²
Gtech CLM 2.0
Gtech
If you want the lawn to look striped without buying a petrol roller mower, the Gtech CLM is the easiest way to get there in a small garden. The rear roller flattens the grass behind the blade for that light-and-dark finish, the battery clicks out for charging indoors, and at this weight it is a pleasure to live with. The trade-offs are the price and the missing mulching plug, but on a tidy lawn under 200 m² neither is a deal-breaker.
Pros
- + Rear roller leaves proper stripes on a small lawn
- + Light and well balanced, easy to lift over a step
- + Click-out battery, simple single-platform system
Cons
- − No mulching plug in the box
- − Pricey next to supermarket own-brands
Flymo EasiStore 300R Li
Flymo
Flymo built the EasiStore range specifically around the problem of where to put a mower in a small home, and it shows: it folds and hangs flat in a way most rivals cannot. The 30 cm deck and compact wheels make it nimble in tight corners, and there is a rear roller for stripes. It is the budget pick rather than the refined one, but for a genuinely small lawn it does the job for less.
Pros
- + Designed to store flat against a wall - smallest footprint here
- + Rear roller for stripes on a budget
- + Light and simple, good first cordless mower
Cons
- − 30 cm deck is slow on anything near 250 m²
- − Build feels plasticky next to Bosch and Gtech
WORX WG779E 40V (2x20V)
WORX
If your small garden has the odd patch of rougher or damper grass that stalls an 18V mower, the WORX WG779E gives you more to work with. It runs two 20V PowerShare packs in series for 40V of cutting torque, the 34 cm deck is the widest in this small-garden group, and the batteries share with the wider WORX 20V range. It is a touch heavier and there are two packs to charge, but it handles a borderline 250 m² lawn that the lighter picks would find a slog.
Pros
- + Twin 20V batteries give more headroom on damp grass
- + 34 cm deck - top of the small-garden range
- + PowerShare batteries fit other WORX 20V tools
Cons
- − Heavier than the single-battery picks here
- − Two batteries to keep charged
How to choose for a small garden
Keep the deck to 30-34 cm
Deck width is the strip the blade cuts in one pass. On a small lawn, a 30-34 cm deck is the sweet spot: wide enough to finish quickly, narrow enough to steer around paths, trees and borders without scalping the edges. Anything wider just adds weight and turning radius you do not need.
Weight is the thing you will notice most
Every mower on this page sits in the 8-13 kg range, and the difference is felt every time you lift it over a step or onto a shelf. The Bosch CityMower and the lighter Flymo are the easiest to carry; the twin-battery WORX is the heaviest of the four. If the user is older, smaller or has back trouble, lean towards the lightest option.
Storage: fold-flat is a real feature
In a flat, a terrace or a small home, where the mower lives matters as much as how it cuts. Flymo's EasiStore design and the Bosch CityMower both fold compact and store flat against a wall. If your only space is a cupboard under the stairs or a slim gap down the side of the house, make fold-flat storage a hard requirement.
Battery platform: borrow it across your other tools
The Bosch CityMower (18V Power for All) and the WORX (20V PowerShare) both run on battery systems shared across strimmers, blowers and hedge trimmers. If you already own - or plan to own - other tools in those ranges, one battery does the lot, and that is real money saved. The Gtech and Flymo run their own packs, which is simpler but less cross-compatible.
Stripes or no stripes
A rear roller is the only way to stripe a lawn. The Gtech CLM 2.0 and Flymo EasiStore 300R Li both have one; the Bosch and WORX use rear wheels and cut cleanly without striping. Decide whether the striped finish matters before you choose, because it narrows the field straight away.
What if my garden grows past 200 m²?
If your lawn is closer to 300-400 m², step up to a 36-40 cm deck and 36V or more - see our main battery-powered lawn mower reviews for the medium-garden picks. For a large lawn with slopes, a self-propelled cordless mower earns its keep. And if you are still weighing up the power types altogether, our cordless vs petrol vs electric guide walks through the decision by garden size.
Brands worth shortlisting for a small garden
- Bosch - the CityMower is purpose-built for small lawns; 18V Power for All shares across tools.
- Gtech - light, single-platform system with a rear roller for stripes.
- Flymo - the EasiStore range is the storage champion for tight spaces.
- WORX - 20V PowerShare twin-battery for a bit more headroom on a borderline lawn.
How we choose
We don't run a test lab and we don't pretend to. Our recommendations are built from published manufacturer specifications, verified owner reviews on Amazon UK and retailer sites, and UK pricing data, cross-checked so the numbers on this page match the numbers you'll find on the box. Where a figure is the maker's claim rather than an independent measurement, we say so.
Rankings are based on cut quality, battery and runtime for the garden size in question, weight, build, and value at UK prices. We update picks when models are discontinued or superseded. We earn affiliate commission on some links, but it never decides the order of a list. More on our method.
