How to Choose the Best Cordless Lawn Mower for Your Garden
Choosing the best cordless lawn mower for UK gardens makes lawn care quicker, easier, and more enjoyable. So, to help you compare options with confidence, here’s what to focus on:
Battery Power, Voltage & Run-Time
Most cordless lawn mowers in the UK use batteries ranging from 18V to 80V. Higher voltage generally means more cutting power for thicker or longer grass, while battery capacity (measured in amp hours, Ah) controls how long the mower can run. For most small and medium gardens, a 36V 4Ah battery strikes a good balance between power and runtime.
Also see our guide to the best garden batteries and chargers for tips on extending mower run-time.
Budget Cordless Lawn Mower for Small UK Gardens
If you’ve got a smaller lawn, you don’t need to overspend on a high-voltage model. A compact 30–34cm cordless mower with a modest 18–20V battery is usually enough to keep the grass tidy without draining your wallet. These lighter, budget-friendly options are also easier to store in tight garden sheds.
Quiet Cordless Mower Options for Urban Gardens
Cordless mowers are naturally quieter than petrol models, making them perfect for urban or suburban gardens. If noise is a concern, look for models marketed as “low-decibel” or “quiet cut” which often feature insulated decks and smoother brushless motors. You’ll keep the neighbours happy while still getting a clean, efficient cut.

Cutting Width and Height Adjustment
Next, check the cutting width. Smaller decks (30–34cm) work well for compact or mid-sized gardens. If your lawn is larger, a wider deck (36cm or more) helps you get the job done faster. Also, go for a mower with adjustable cutting heights — it makes seasonal mowing much easier.
Weight and Manoeuvrability
Weight matters more than you might think. A lighter mower is easier to carry, turn, and store — especially useful in tight spaces or uneven areas. If you’ll be lifting it up steps or around obstacles, double-check the weight before buying.
Grass Collection and Mulching
Most cordless models come with a grass box, which makes clean-up simple. Some also offer mulching, which finely chops clippings and returns them to the lawn for a natural boost. If you don’t want to empty a box every few minutes, mulching might be a bonus worth having.
Maintenance and Noise
Cordless mowers are refreshingly low-maintenance. There’s no petrol, oil, or tangled cords to mess with. Go for models with easy battery access and quieter motors — ideal if you want to mow early or avoid disturbing your neighbours.
Garden Size Suitability
Lastly, choose a mower based on the size of your lawn:
- Small gardens: Look for compact, lightweight models with a 30–34cm cutting width
- Medium gardens: Aim for 34–38cm decks with solid battery life
- Large gardens: Consider mowers with dual batteries and 40cm+ cutting widths
When you match the mower to your garden’s size and your needs, you’ll avoid wasting money — and make lawn care feel a lot less like hard work.

Best Cordless Lawn Mower for Large Gardens UK – The Greenworks 48V
If you’ve got more than 300 m² to cover, you’ll want dual-battery power, a wide cutting deck, and solid run-time. The Greenworks 48V (2×24V) cordless lawn mower is widely rated as one of the best cordless mowers for large UK gardens, combining power with efficiency.
Best Self-Propelled Cordless Lawn Mower UK Models
A self-propelled cordless lawn mower takes the strain out of mowing sloped or large gardens. These UK models combine long battery life with smooth handling, giving you petrol-like performance with far less effort.
The Greenworks 48V is designed for medium to large lawns (≈ 200–400 m²). With the standard 2Ah batteries you can expect around 14 minutes / ~210 m² coverage, while larger 4Ah batteries stretch this toward 28 minutes / ~420 m², depending on grass length and conditions. This makes it a premium option among the best battery lawn mower UK picks.
Greenworks 48V Cordless Lawn Mower – Key Highlights

Cordless vs Petrol Lawn Mowers – Which Is Better for UK Gardens?
When choosing between a cordless lawn mower and a petrol model, the decision often comes down to convenience, cost, and your garden size. Here’s how they compare:
Power & Performance
- Petrol mowers are traditionally more powerful, handling very long or wet grass with ease.
- Cordless mowers have improved massively in recent years. Models with 40V+ batteries and brushless motors now deliver performance that’s more than enough for small to medium UK gardens.
Noise & Vibration
- Petrol engines are loud and can be disruptive in built-up areas.
- Cordless models run much quieter, making them ideal if you like to mow early mornings or evenings without annoying the neighbours.
Maintenance
- Petrol machines need fuel, oil, spark plugs, and regular servicing.
- Cordless mowers are almost maintenance-free — just charge the battery and clean the blades.
Cost Over Time
- Petrol mowers often cost less upfront, but fuel and servicing add up.
- Cordless mowers have a higher initial price but cheaper long-term running costs, especially if the batteries work across other garden tools.
Environmental Impact
- Petrol models emit fumes and greenhouse gases.
- Cordless mowers are cleaner, eco-friendly, and align with the UK’s push towards sustainable gardening.
👉 Verdict: For most small to medium UK gardens, cordless is now the smarter choice. Petrol is still useful if you’ve got a very large or rough lawn, but for everyday mowing, cordless wins on simplicity, cost, and convenience.

Not every garden needs a big, heavy mower. The best small cordless mower models are lightweight, easy to manoeuvre, and ideal for tight corners or townhouse gardens. They make quick work of smaller lawns while still offering a professional-looking finish.

Cordless Lawn Mower FAQs – What UK Buyers Want to Know
They’ve come a long way — and yes, many cordless mowers now offer impressive cutting power, especially those with 40V+ battery systems. While they might not match the raw torque of high-end petrol models, they easily handle everyday mowing with far less noise, hassle, and maintenance.
It depends on the mower and your lawn conditions, but most cordless models give you 30–45 minutes on a full charge. That’s usually enough for a small to medium garden. Keep in mind that thick or wet grass can drain the battery faster.
Absolutely — and it’s one of the biggest perks. Many brands use shared battery systems, so you can power multiple tools with just one battery type. For example:
– Worx batteries work with all tools in their PowerShare range
– Einhell uses the Power X-Change system across their entire lineup
– Greenworks offers compatibility across dozens of garden and power tools
This makes building your cordless tool kit easier — and saves money over time.
Technically, yes — but it’s not ideal. Wet grass clumps more easily, which can clog the deck and strain the motor. If you do need to mow after rain, choose a model with strong power output and clean the blades afterward to keep it running smoothly.
Definitely. Most models include safety keys, two-hand start systems, and quick-start buttons — no more yanking cords or dealing with fuel. They’re also quieter and lighter than petrol mowers, which makes them perfect for beginners, older users, or anyone who just wants a simpler mow.
Check out my top picks to find the best cordless lawn mower for UK gardens based on your needs and budget.
Most lithium-ion batteries will give you 500–1,000 charge cycles, which usually means 3–5 years of use before capacity drops noticeably. With proper care (avoiding overcharging, storing indoors during winter), some batteries can last even longer. Replacement packs are widely available from major brands, and many ranges let you share one battery across multiple tools.
Yes — modern cordless mowers handle the damp, variable UK weather surprisingly well. While wet grass can drain the battery faster and may clog the deck, higher-voltage models (40V+) cut effectively even in less-than-perfect conditions. For small to medium UK gardens, cordless mowers are more than capable year-round, and their quiet motors mean you can mow whenever the weather allows.
They do — but choose carefully. Lightweight models are easier to push over bumps, while wider, heavier decks can struggle on steep slopes. If your lawn has lots of uneven ground, look for:
– Low weight (under 12kg) for easy handling
– Large wheels that glide over rougher areas
– Adjustable cutting heights so you don’t scalp the grass
For steep or very uneven gardens, a self-propelled cordless mower is worth considering.
Yes — for most UK gardens, cordless mowers are worth it because they’re cleaner, quieter, and more convenient than petrol or corded models. They’re especially practical for gardens under 500m² where run-time is rarely an issue.
A quality lithium-ion battery should last 30–60 minutes per charge depending on voltage and capacity. With proper care, you can expect 3–5 years of use before replacement is needed.
Most cordless mowers can handle slightly damp grass, but performance drops in heavy wet conditions. For the best results, wait for the lawn to dry, or mow at a higher cutting height if you need to tackle wet growth.
Look for models with 46 cm+ cutting decks, dual batteries, and self-propelled drive — like the Greenworks 48V.
Budget models like the Einhell GE‑CM 18/30 Li are highly rated and affordable.
The best cordless lawn mower depends on your garden size, terrain, and storage space. For small lawns, a compact mower with a 30–34 cm deck is ideal, while larger lawns benefit from self-propelled options with dual batteries.
Look for models with at least 30 minutes of runtime per battery and adjustable cutting heights. Brands like Worx, Bosch, and Hyundai remain top choices for cordless lawn mowers UK gardeners who want reliability and value.
