What to Look for in a Cordless Lawn Mower
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 and Run-Time
Let’s start with battery life. Look for lithium-ion batteries that provide at least 30–45 minutes of run-time. In most cases, higher voltage (like 40V or 48V) means more power — which comes in handy when mowing thick or damp grass.
📏 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.

Greenworks 48V Cordless Lawn Mower – Best for Large Gardens
If you’ve got a wide, open lawn to tackle, the Greenworks 48V brings serious power and reach. Thanks to its 46cm cutting width and dual battery setup, it makes quick work of larger lawns without compromising on cut quality.
Why It Stands Out:

- Great for big, open gardens
- Consistent power with long run-time
- Soft-grip handle makes mowing more comfortable
- Heavier than most cordless models (27.5kg)
- Takes up more space in the shed or garage

If you’re on a budget or have a small garden to maintain, the Einhell GE-CM 18/30 Li is a smart pick. It’s lightweight, affordable, and perfect for straightforward mowing jobs where simplicity beats bells and whistles.

Frequently Asked Questions
Are cordless mowers as powerful as petrol ones?
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.
How long do the batteries last?
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.
Can I use the same battery across other tools?
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.
Can I mow wet grass with a cordless mower?
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.
Are cordless mowers safe and easy to use?
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.

Final Thoughts
Choosing the best cordless lawn mower really comes down to what matters most to you — whether that’s power, price, weight, or just plain simplicity.
After testing a wide range of models, I keep coming back to the Worx WG779E as my top pick for 2025. No matter your garden size or budget, this guide should help you find the best cordless lawn mower for UK gardens with confidence. It’s reliable, lightweight, and delivers great results for small to medium gardens — all without the noise, maintenance, or fumes of petrol mowers.
But if you’ve got a larger lawn and want more power, the Greenworks 48V gives you impressive performance and a wider cutting deck to match. On the other hand, if you’re sticking to a budget or only need to tidy up a small lawn, the Einhell Power X-Change gets the job done without cutting corners.
