🏆 Our Top Picks
Here are the best cordless lawn mowers for UK gardens, based on real-world performance, battery systems, brand trust, and overall value.
⭐ #1 Pick – Best Cordless Mower Overall
If you want the strongest cordless mower on this list and are happy to spend more for a trusted tool brand, the Makita DLM432Z / DLM432 18V LXT Cordless Lawn Mower is my new top pick. It costs more than budget cordless mowers, especially if you need batteries and a charger, but it has the brand trust, cutting width and battery-system appeal that many UK buyers look for.
The important thing with Makita is to check what is included. Some listings are body-only, which is ideal if you already own compatible Makita 18V LXT batteries. Other retailers may let you add batteries and a charger, which gives a fairer comparison against all-in-one cordless mower bundles from Worx, Ryobi or Bosch.
- 43 cm cutting width for quicker mowing than smaller 32–37 cm cordless models
- Runs on Makita’s widely used 18V LXT battery platform
- Strong choice if you already own Makita batteries or other LXT tools
- Better suited to larger or more demanding lawns than compact cordless mowers
- Trusted premium tool brand with strong long-term battery-system appeal
Best for: UK gardeners who want a more premium cordless mower, especially if they already own Makita 18V batteries or are happy to build around the Makita LXT system.

Best Cordless Lawn Mowers for UK Gardens
Cordless lawn mowers have reached the point where most UK gardens no longer need petrol. They are quieter, easier to start, and far simpler to live with — especially on the damp, uneven lawns common across Britain.
The real advantage is not just convenience. It is flexibility. You can mow earlier without upsetting neighbours, stop when the weather turns, and avoid dealing with fuel, fumes or stubborn pull-cords altogether.
This guide compares cordless lawn mowers for different garden sizes, budgets and battery systems, from compact models for small lawns to more powerful options suited to medium and larger gardens. We have focused on real-world usability, brand trust, what is included in the box, and long-term ownership value — not just headline specs.
For a broader look at how cordless tools fit together across the garden, see our guide to Garden Tools and Equipment.
Below, you’ll find our detailed reviews of each mower, starting with the strongest overall pick, then moving through mid-range, value and compact options.
Best Overall if Budget Allows
Makita prices vary depending on batteries and charger options. Compare the Makita price at Tooled-Up .
If you want the most powerful mower on this list and budget isn’t the main concern, the Makita DLM432Z delivers the strongest cutting performance here. Its twin 18V LXT battery setup (36V combined) provides strong cordless cutting power without the noise, fumes or maintenance of petrol.
The wider 43 cm deck makes it more efficient on larger lawns, reducing the number of passes needed compared to 33–37 cm models. In typical UK conditions, it’s best suited to larger gardens of up to 575 m², especially where grass can grow thicker or more uneven.
Because it runs on Makita’s professional-grade LXT system, it’s also part of one of the most extensive cordless tool ranges available — making it a strong long-term investment if you already use Makita tools.
Key Features
- Twin 18V Makita LXT battery system, giving 36V combined power
- 43 cm cutting deck for quicker mowing than smaller 32–37 cm cordless models
- 13 cutting height settings from 20–75 mm
- 50 L grass collector for fewer emptying stops
- Suitable for medium to larger lawns, especially if you already own Makita 18V batteries
- Often sold as a bare tool, so batteries and charger may need to be bought separately
- 1-year standard warranty, extendable to 3 years when registered within 30 days, subject to Makita’s terms
Best for: Larger lawns (500-575 m²) where cutting power and deck width matter most.
Why buy: Strongest cutting performance in this guide and compatible with Makita’s extensive LXT tool range.
Why skip: Often sold as a bare tool — batteries and charger may need to be purchased separately.
⚠ Buyer warning: The Makita DLM432Z is frequently sold as a bare unit. If you don’t already own Makita LXT batteries and a charger, the total cost rises significantly once added. It offers excellent value mainly for those already invested in the Makita ecosystem.
Best Mid-Range Battery System
If you want a cordless mower from a recognisable tool brand but do not want to spend Makita money, the Ryobi RY18LM37A-140 18V ONE+ Cordless 37cm Mower is one of the strongest mid-range choices on this list.
The 37 cm cutting width puts it in the same practical garden-size category as the Worx, making it well suited to typical small-to-medium UK lawns. The difference is the Ryobi ONE+ battery system, which gives it stronger long-term appeal if you might add other cordless garden tools later.
It is also a simpler buy than bare-tool mowers because this starter kit usually includes a 4.0Ah battery and charger. That makes the real price easier to understand, especially when comparing it with Makita models that are often sold without batteries.
Key Features
- 37 cm cutting width for small-to-medium UK lawns
- 18V ONE+ battery platform
- Usually supplied with 1 × 4.0Ah battery and charger
- 45 L grass catcher capacity
- 6-position cutting height adjustment from 25–75 mm
- EasyEdge grass comb for mowing closer to borders
- Folding handles and collapsible grass catcher for easier storage
- 3-year warranty available when registered, depending on retailer terms
Best for: Medium lawns around 300–500 m² where you want a recognised cordless battery system without paying full premium-brand prices.
Why buy: Stronger brand trust than many budget cordless mowers, with a useful 37 cm deck and the Ryobi ONE+ battery ecosystem behind it.
Why skip: Not as powerful or wide-cutting as the Makita, and still fairly expensive compared with cheaper cordless mower bundles.
Best Value Cordless Mower Bundle
⚠️ Stock note: Amazon availability for the Worx WG737E has been patchy recently, and the link may occasionally redirect to a different Worx mower model. Check the model number carefully before buying, or compare availability with other retailers.
The Worx WG737E is designed for medium-sized UK lawns where you want a complete cordless mower bundle without stepping into premium-brand pricing. Its 40V setup, using two 20V PowerShare batteries, gives it enough cutting power for regular weekly mowing and typical seasonal growth.
In real-world use, it handles uneven patches and typical British grass conditions without fuss. The 37 cm deck is well suited to fenced suburban gardens, offering a good balance between coverage and manoeuvrability.
Because it’s part of Worx’s PowerShare system, the same batteries can be used across compatible strimmers, hedge trimmers and other garden tools. If you’re building a cordless setup over time, that flexibility makes long-term ownership more economical.
Key Features
- Dual 20V batteries, giving 40V combined power
- 37 cm cutting width for medium UK lawns
- 6 cutting height settings from 20–70 mm
- 30 L grass collection box
- Foldable handle for easier shed or garage storage
- Part of the Worx PowerShare battery system
- 2-year standard warranty, extendable to 3 years when registered within 30 days, subject to Worx terms

Tester’s note: We’ve used the Worx WG737E for over a year on a larger-than-average UK lawn with uneven patches and seasonal growth. It’s handled regular mowing without fuss.
Best for: Medium UK lawns (300–500 m²)
Why buy: Strong balance of performance, run-time and battery ecosystem flexibility.
Why skip: Heavier than entry-level 18V models and more than small lawns typically require.
Best for Small Lawns
For very small UK lawns and tight urban spaces, the Bosch CityMower 18V-32 keeps things simple. It’s lightweight, quiet, and easy to manoeuvre — making it well suited to courtyards and compact gardens where storage space is limited.
It runs on Bosch’s Power for All Alliance battery system, meaning the same 18V battery can be shared across compatible Bosch, Gardena and select Flymo tools — a practical advantage for smaller sheds.
In real UK conditions, it’s best suited to lawns under around 200–300 m² (depending on the exact 18V-32 model variant) . It’s not designed for tackling long or neglected grass, but for regular, light mowing in compact spaces, it delivers neat results with minimal effort.
Key Features
- 18V Power for All battery system
- 32 cm cutting deck for small UK lawns
- ErgoFlex handles for improved comfort
- 3 cutting height settings
- Lightweight, compact design for easier storage
- Best suited to lawns under around 300 m²
- 2-year standard Bosch guarantee, extendable to 3 years when registered within 4 weeks; batteries, chargers and wearing parts may be excluded
Best for: Lawns under 300 m² and small urban gardens.
Why buy: Lightweight, compact and easy to store.
Why skip: Limited power and run-time for thicker or overgrown grass.
Best Compact Storage Option
If storage space is your biggest constraint, the Flymo SimpliStore 340 Li earns its place on this list. It folds flat for compact storage, making it ideal for sheds, cupboards, and smaller garages where space is limited.
This isn’t a power-focused mower. Instead, it’s built for light, regular mowing on small to medium UK lawns that are already kept under control. For quick weekly cuts, it’s simple to handle and easy to manoeuvre.
Unlike Bosch or Makita, it doesn’t sit within a large shared battery ecosystem — the 18V battery is Flymo-specific — so it’s best suited to buyers who just want a straightforward standalone mower rather than building a cordless tool system.
Key Features
- Two 20V Li-ion batteries, giving 40V combined power
- 34 cm cutting width for small to medium UK lawns
- 5 cutting height settings from 20–60 mm
- 35 L grass collection box
- Close-edge cutting design for mowing nearer borders and flowerbeds
- Folding handles and vertical storage design for compact sheds or garages
- Lightweight body with carry handle for easier moving and storage
- Standard 1-year manufacturer warranty, usually extendable to 2 years when registered within 3 months, subject to Flymo terms
Best for: Quick weekly cuts on small to medium lawns.
Why buy: Excellent for tight storage spaces and simple, fuss-free mowing.
Why skip: Limited battery compatibility and not designed for heavy or overgrown grass.
Battery Systems Explained
Most cordless mowers belong to wider battery ecosystems, meaning you can reuse batteries and chargers across multiple tools. If you plan to build a cordless setup over time, choosing into one system can save money and reduce clutter.
| Brand | System | Shared With | Notes |
|---|---|---|---|
| Makita | LXT 18V (twin-battery for 36V mowers) | Makita LXT cordless power tools and garden tools | Premium, heavy-duty platform; best if you already own Makita batteries |
| Ryobi | ONE+ 18V | Ryobi ONE+ DIY, home and garden tools | Strong mid-range ecosystem with wide tool compatibility |
| Worx | PowerShare 20V / 40V | Worx DIY and garden tools | Good value ecosystem, especially for mower bundles with batteries included |
| Bosch | Power for All Alliance 18V | Bosch, Gardena and selected other compatible tools | Useful cross-brand compatibility for smaller garden tool setups |
| Flymo | Flymo 18V system | Mainly selected Flymo cordless garden tools | More of a standalone choice than a broad cordless tool ecosystem |

🌿 How to Choose the Best Cordless Lawn Mower for Your Garden
When choosing the best cordless lawn mower for a UK garden, focus on the practical details that affect real mowing: lawn size, battery setup, storage space and what is actually included in the box.
1. Match the mower to your lawn size
Be realistic about your lawn size. Damp grass, uneven patches and fast spring growth can all reduce real-world battery life.
- Very small lawns and courtyards: Bosch CityMower 18V-32
- Small lawns where storage is tight: Flymo SimpliStore 340 Li
- Medium lawns: Ryobi RY18LM37A-140 18V ONE+
- Medium lawns where value matters most: Worx WG737E 40V
- Medium to larger lawns: Makita DLM432Z 36V
Tip: If your grass gets long, raise the cutting height and mow in stages. Cordless mowers cope far better when they are not asked to take everything in one pass.
2. Check what is included
Cordless mower prices can be misleading because some models are sold as complete kits, while others are sold as bare tools.
- The Makita DLM432Z is often sold body-only, so batteries and charger may need to be bought separately.
- The Ryobi RY18LM37A-140 starter kit usually includes a 4.0Ah battery and charger.
- The Worx WG737E usually includes batteries and charger, making it easier to compare as a complete bundle.
- The Bosch and Flymo options are often sold as complete small-lawn kits, but always check the listing carefully.
This matters because a mower that looks cheaper at first can cost much more once batteries and charger are added.
3. Check battery capacity
Battery capacity matters just as much as voltage. A higher Ah rating usually means longer run-time, although wet grass, thick growth and uneven lawns can drain batteries faster.
- 4.0Ah+ is useful for many medium UK gardens.
- Smaller batteries are fine for compact lawns and quick weekly cuts.
- Wider mowers cut faster, but they also need enough battery capacity to support the larger deck.
4. Think about battery ecosystems
If you plan to buy other cordless tools, such as a strimmer, hedge trimmer or blower, choosing a shared battery platform can save money and storage space.
- Makita LXT: best premium ecosystem, especially if you already own Makita tools.
- Ryobi ONE+: strong mid-range system with wide DIY and garden tool compatibility.
- Worx PowerShare: good value ecosystem, especially for cordless garden bundles.
- Bosch Power for All Alliance: useful cross-brand compatibility with Bosch, Gardena and selected other tools.
- Flymo 18V: simpler standalone choice if you just want an easy mower.
5. Storage and weight matter
If you need to lift the mower into a shed, cupboard or garage, do not ignore weight and folding design.
- Lighter models like the Bosch and Flymo are easier to live with in compact gardens.
- Fold-flat handles make a big difference in small sheds and garages.
- Larger models like the Makita cut faster, but need more storage space and are heavier to move.
For small UK gardens, the easiest mower to store is often the one you will actually use most often.
🌻 Final Thoughts
Cordless lawn mowers have matured to the point where most UK gardens no longer need petrol power. Modern battery models are quieter, cleaner and far easier to live with, while still delivering a neat, even cut.
If you want the strongest overall mower and are happy to spend more, the Makita DLM432Z is the best pick in this guide. It has the widest cutting deck, strong brand trust and excellent long-term appeal if you already use Makita 18V LXT batteries.
For a more affordable recognised battery system, the Ryobi RY18LM37A-140 is the strongest mid-range choice. It gives you a 37 cm cut, a trusted ONE+ platform and a battery and charger included.
If you want a value cordless bundle, the Worx WG737E is still a very good option for medium UK lawns, especially when it is in stock at a competitive price.
For small lawns, the Bosch CityMower 18V-32 keeps things simple, light and easy to store. If storage space is your biggest concern, the Flymo SimpliStore 340 Li is the most practical compact option.
Whichever model you choose, switching to cordless mowing makes garden care quieter, cleaner and significantly easier without sacrificing results for most UK lawns.

⚡ Best Cordless Lawn Mowers UK – Frequently Asked Questions
Do cordless mowers work on damp grass?
They can, but you’ll get the best results once the lawn surface is mostly dry. Wet grass drains batteries faster and can clog the blades.
How long do the batteries last?
Most modern lithium packs provide 30–45 minutes per charge and last 3–5 years with proper care.
Can a cordless mower cut long grass?
Yes, but it’s best to raise the cutting height first and mow in stages. Most cordless models cope well if the grass isn’t damp or over 15 cm long. For overgrown lawns, a strimmer pass first helps prevent clogging.
Are cordless mowers powerful enough for large lawns?
Modern 36–40 V systems such as Worx PowerShare and Makita LXT easily handle 300–500 m² gardens. The key is using high-capacity batteries (4.0 Ah or higher) and keeping blades sharp for efficient cuts.
How many square metres can a 4.0Ah battery mow?
Rough guide: ~100–150 m² per 18–20V 4.0Ah pack in average conditions. Wet/long grass reduces this; sharp blades increase it.
