Battery-powered lawn mowers have crossed a critical threshold. Models from EGO, Makita, and Greenworks now match petrol mowers for cutting power, outlast corded electrics without the trip hazard, and produce zero fumes — a genuine advantage when mowing in enclosed spaces or near children and pets. In 2026, if you have a garden up to around 500 square metres, a battery mower is not just a viable alternative to petrol: for many UK homeowners it is the better choice outright.
This guide covers nine current models suited to a range of garden sizes and budgets. We have paid particular attention to battery voltage, runtime, the interchangeability of batteries across tool ecosystems, and real-world cutting performance on the damp, often coarse grass that typifies UK lawns.
| Model | Approx. Price | Voltage | Runtime (per charge) | Cutting Width | Best For |

Prices are approximate UK RRP as of early 2026. Runtime varies with grass conditions, terrain, and cutting height selected. Always check current retailer pricing.
One of the biggest decisions when buying a battery mower is not just which mower to buy, but which battery ecosystem to buy into. Batteries from one brand rarely work in another brand's tools. If you already own cordless drills, hedge trimmers, or leaf blowers from a particular brand, you may be able to buy the mower as a bare tool (without battery) and use the batteries you already own — saving £50–£150 on the purchase price.
Here is a breakdown of the main battery platforms available in the UK:
EGO's 56V platform is purpose-built for garden power tools and is the most powerful ecosystem on this list. The 56V system is exclusive to EGO — you cannot use EGO batteries in other brands' tools. However, EGO's range is comprehensive: chainsaw, hedge trimmer, leaf blower, string trimmer, and ride-on mower all run on the same battery. If you are building a complete garden tool kit from scratch, EGO's ecosystem is arguably the best starting point in 2026. Batteries range from 2.5Ah to 10Ah; for mowing a garden of 300–500 sq. metres, a 5Ah or 7.5Ah battery is recommended.
Makita's LXT 18V platform is one of the most widely used cordless systems in the UK, with over 300 compatible tools. The lawn mowers in Makita's range use two 18V LXT batteries in series to achieve an effective 36V — giving genuine cutting power without needing a proprietary high-voltage battery. If you already own Makita LXT batteries from other tools (drills, saws, etc.), the DLM432Z or DLM461Z bare tools represent outstanding value. Makita also offers a 40V Max XGT system for higher-demand applications.
Bosch's ProCORE 18V batteries are among the most popular in the UK, compatible with hundreds of Bosch blue (professional) and green (DIY) tools. Many Bosch mowers use two 18V batteries. However, note that Bosch Green (DIY) and Bosch Blue (professional) batteries are not cross-compatible — check which range your existing tools belong to. The AdvancedRotak range targets the serious home gardener; the UniversalRotak range suits lighter use.
Ryobi's ONE+ platform is the most accessible entry point into battery garden tools. The ONE+ 18V system alone offers over 130 tools, and Ryobi's mowers typically use dual 18V batteries to deliver 36V. The key advantage is price: Ryobi batteries and tools are generally cheaper than EGO, Makita, or Bosch equivalents. Quality has improved significantly and for gardens up to 400 sq. metres, the Ryobi 36V mowers perform well. Ryobi also offers a separate 40V HP system for heavier-duty work.
Stihl's AK system is a 36V platform covering trimmer, blower, hedge cutter, chainsaw, and mower. Stihl build quality is exceptional, and the AK system's build-in safety and thermal management is superior to cheaper alternatives. AK batteries are interchangeable across all Stihl AK tools. The premium is significant — Stihl tools typically cost more than equivalent EGO or Ryobi products — but the quality and dealer support justify this for many buyers.
Higher voltage does not always mean more power in the garden. A well-engineered 36V system with high-quality cells can outperform a cheaply built 40V product. EGO's 56V ARC Lithium, for example, is consistently benchmarked as one of the most powerful battery mowers available despite some competitors offering nominally higher voltages. Focus on brand reputation, tested performance, and Ah (ampere-hour) capacity rather than voltage alone.
The EGO LM1702E-SP is the battery mower we would recommend to most UK homeowners in 2026. It combines EGO's class-leading 56V ARC Lithium platform with a 42 cm cutting deck, brushless motor, and self-propelled drive — the full specification you need for gardens up to around 400 square metres. The 4.0Ah battery included in the kit is sufficient for a 300 sq. metre lawn; upgrading to a 5.0Ah or 7.5Ah battery (sold separately) extends this meaningfully.
The brushless motor delivers outstanding cutting power on damp, thick grass — a scenario that defeats many cheaper battery mowers. EGO's 6-position height adjustment (25–95 mm) and 55-litre grass bag round out a very capable package. Runtime on the supplied 4.0Ah battery is approximately 35–40 minutes under normal conditions.
EGO's larger self-propelled model steps the cutting width up to 50 cm and typically ships with a larger capacity battery, extending runtime to around 55–60 minutes per charge under normal conditions. That translates to effective coverage of 500 sq. metres — enough for many UK gardens that would otherwise require petrol. The wider deck reduces mowing time significantly compared to the 42 cm model.
As with all EGO tools, the LM2024E-SP uses EGO's 56V ARC Lithium batteries — if you already own EGO tools, the bare tool version is considerably cheaper and well worth considering.
Greenworks has built a strong reputation in the UK for capable, affordable battery garden tools. The GD60LM46SP runs on Greenworks' 60V platform and delivers self-propelled drive across a 46 cm deck — a practical choice for gardens between 300 and 500 sq. metres. Runtime of around 45 minutes per charge positions it well against the EGO 42 cm model at a lower price point.
The 60V Greenworks system is separate from its 24V and 40V ranges — batteries are not cross-compatible across these sub-platforms. If you are starting fresh with Greenworks, the 60V range is the one to invest in for larger garden tools.
If you already own Makita LXT 18V batteries from a drill, circular saw, or other tool, the DLM432Z bare tool is one of the best value battery mowers you can buy. It uses two 18V LXT batteries in series for a combined 36V output, driving a 43 cm steel deck with brushless motor. Cutting performance is excellent, particularly with two 5.0Ah or 6.0Ah batteries fitted.
The DLM432Z does not include a self-propelled drive — it is push only. For flat gardens up to around 400 sq. metres, this is rarely an issue. For sloping gardens, consider the DLM461PT2 which includes a larger deck and self-propelled option.
The AdvancedRotak 36-750 uses two Bosch 18V batteries and is compatible with Bosch's broad ecosystem of green (home and garden) 18V tools. The 44 cm cutting width, 55-litre collector, and six cutting height settings (20–70 mm) cover the essentials well. Runtime on two 4.0Ah batteries is approximately 35–40 minutes.
The Bosch's strong suit is ecosystem integration: if your shed already contains Bosch 18V hedge trimmers, leaf blowers, or string trimmers, the mower becomes very cost-effective when purchased as a bare tool. Bosch's quality control and after-sales support in the UK is well-regarded.
Ryobi's 36V HP (High Performance) mower uses two 18V ONE+ batteries and delivers a step up in power over earlier Ryobi models. The 46 cm deck handles medium-sized lawns comfortably, and the 50-litre collector keeps emptying trips reasonable. The brushless motor manages damp, heavy grass better than older Ryobi brush-motor alternatives.
If you own Ryobi ONE+ tools — and millions of UK homeowners do, given the platform's strong presence in DIY retailers — the RLM36X46HP50 bare tool price represents excellent value. Ryobi's extensive service network and widely stocked spare parts are a practical advantage.
Stihl's RMA 443 TC runs on the AK 36V system and is the premium option in this guide. The build quality is exceptional — Stihl has a long history of producing professional-grade outdoor power tools, and it shows in the RMA 443 TC's components and finish. The 43 cm deck, brushless motor, and variable-speed self-propelled drive handle UK lawn conditions confidently, including on damp grass where cheaper motors struggle.
Runtime of up to 50 minutes per charge on a 4.0Ah AK battery is competitive, and Stihl's AK range includes hedge trimmers, strimmers, and blowers — so investment in the ecosystem pays dividends across the garden. The price is higher than most alternatives, but Stihl's dealer network and parts availability are second to none.
For smaller gardens and those new to battery mowers, the Greenworks 40V G40LM41K2 is the most accessible entry point in this guide. The 41 cm cutting width and 30-minute runtime (on the supplied 4.0Ah battery) are suitable for lawns up to around 250 sq. metres — think a typical UK semi-detached garden. Push-only operation keeps the price down.
Do not expect it to match EGO or Stihl for heavy-duty cutting, but for regular maintenance of smaller lawns it is capable and reliable. The Greenworks 40V battery is compatible with the brand's 40V hedge trimmer and leaf blower, making it a sensible starting point for a budget battery tool ecosystem.
Honda's HRG466XBE is the premium walk-behind battery mower for homeowners who prioritise cut quality above all else. Honda's IzyMow battery platform drives the 46 cm deck via a brushless motor, and Honda's engineering pedigree shows in the finish of the cut — particularly on fine or ornamental lawns where striping and consistent height matter.
Runtime of up to 50 minutes per charge is competitive. The 46-litre rear collector and Honda's NeXiTE composite deck material keeps weight manageable. At around £699, it costs more than EGO, but for a fine lawn or a gardener who values Honda's long-term reliability, it justifies the premium.
Voltage determines peak power; ampere hours (Ah) determine how long the battery lasts. A 56V 5.0Ah battery stores significantly more energy — and thus gives longer runtime — than a 56V 2.5Ah battery. For gardens over 300 sq. metres, opt for at least a 4.0Ah battery, and consider whether you can run a second battery to swap mid-mow without waiting for a charge.
All the mowers recommended in this guide use brushless motors. Brushless motors are more efficient (more cutting time per charge), run cooler, require less maintenance, and last longer than older brushed-motor designs. Avoid any battery mower without a brushless motor if you are spending over £200.
Self-propelled mowers drive themselves forward at a pace set by the operator, reducing physical effort significantly — particularly on slopes or over a large area. For gardens over 300 sq. metres, or for anyone with mobility concerns, self-propelled drive is strongly recommended. For small, flat gardens, push models are cheaper and lighter.
The right cutting width depends on your lawn size. A 41 cm deck suits gardens up to 200 sq. metres. A 43–46 cm deck handles up to 400 sq. metres. A 50 cm deck is the most efficient choice for gardens approaching 500 sq. metres. Wider is not always better if your garden has narrow passages or complex borders.
A 40–55 litre rear collector is standard for walk-behind battery mowers. On a 400 sq. metre lawn, expect to empty the collector two to three times per session. Many models also offer side-discharge or mulching modes, which can reduce or eliminate the need to empty the collector entirely.
Standard chargers typically recharge a 4.0Ah battery in 60–90 minutes. Rapid chargers (available for EGO and some other brands) can halve this. If your garden is too large to complete in a single charge, a rapid charger or a second battery is worth the additional investment.
| Factor | Battery Mower | Petrol Mower |
|---|---|---|
| Garden size suitability | Up to ~600 sq. m (with dual batteries) | Unlimited |
| Running cost | Very low (electricity only) | Higher (fuel, oil, spark plugs) |
| Maintenance | Minimal (no oil changes, carburettor issues) | Annual service required |
| Noise | Significantly quieter | Louder |
| Emissions | None at point of use | CO and NOx exhaust |
| Start-up | Instant button start | Pull-cord or electric start |
| Weight | Heavier (battery weight) | Varies; often similar or lighter |
| Purchase price | Higher (battery included) | Can be lower at entry level |
| Winter storage | Remove battery, store cool and dry | Drain fuel or use stabiliser |
Runtime varies significantly by model, battery capacity, grass height and thickness, and terrain. Entry-level 40V mowers with a 2.0Ah battery may last only 20–25 minutes. Premium models like the EGO 56V with a 7.5Ah battery can exceed 60 minutes. Check the battery Ah rating carefully — it is a more reliable guide to runtime than the voltage alone.
Only if the tools share the same battery platform from the same brand. Makita 18V LXT batteries work in all Makita LXT tools, including the DLM432Z mower. Ryobi ONE+ 18V batteries work across all Ryobi ONE+ tools. EGO 56V batteries are specific to EGO tools. Bosch 18V batteries work within the Bosch 18V range (green or blue, separately). Do not attempt to use batteries across brands — even if connectors appear similar, voltage and cell specifications differ.
Battery mowers are safe to use in light drizzle, but it is never advisable to cut soaking wet grass — this is true for petrol mowers too, as wet clippings clump, block the collector, and can lead to an uneven cut. Most modern battery mowers are sufficiently weather-resistant for UK conditions. Check the IPX water resistance rating if you are concerned; most quality models achieve IPX4 or better.
Lithium-ion batteries in quality brands like EGO, Makita, and Bosch typically last 500–1,000 charge cycles before capacity drops noticeably. For a homeowner who charges the battery 30–50 times per year (i.e., each mowing session), that equates to 10–20 years of use. Proper storage — keeping the battery at around 40–60% charge over winter, in a dry, temperate environment — significantly extends cell life.
For gardens under 200 sq. metres, the Greenworks 40V G40LM41K2 at around £249 is an excellent starting point. If you want to invest in a platform you can grow, the EGO LM1702E-SP is worth the additional outlay — the 56V ecosystem includes tools that will serve you for years.
Yes, if they include a rear roller. Several models in this guide — including the Bosch AdvancedRotak — incorporate a rear roller for striping. EGO also offers an optional rear roller attachment for some models. Without a rear roller, all mowers produce a cut lawn, but the classic alternating dark and light stripes require that roller to bend the grass in alternating directions.
Not with current technology in a single charge. One acre is approximately 4,000 square metres — eight to ten times what a single battery charge in most walk-behind mowers can cover. If you have an acre to mow, a petrol mower or ride-on tractor remains the practical choice. The exception is EGO's battery ride-on range, though these remain expensive and are best suited to flat terrain.
Makita's 18V LXT system boasts over 300 compatible tools and is widely regarded as the most extensive professional-grade ecosystem. Ryobi ONE+ covers over 130 tools at a more accessible price point. EGO offers the most capable garden-specific ecosystem. For the broadest general coverage across both garden and workshop tools, Makita or Bosch 18V are the strongest choices.
The EGO LM1702E-SP is our top recommendation for most UK homeowners in 2026. It combines the most powerful and reliable battery platform in the consumer garden tool market with a practical self-propelled 42 cm design. For gardens up to 400 sq. metres, it is competitive with petrol on every meaningful measure and superior on noise, emissions, and maintenance.
Step up to the EGO LM2024E-SP if your garden stretches toward 500 sq. metres, or invest in a second battery for back-to-back sessions without waiting for a recharge.
Already deep in a battery ecosystem? The Makita DLM432Z (for LXT owners), Bosch AdvancedRotak 36-750 (for Bosch 18V owners), and Ryobi RLM36X46HP50 (for ONE+ owners) are all excellent bare-tool options that leverage batteries you already own.
For the best cut quality on ornamental or fine lawns, the Honda HRG466XBE earns its premium. And for those who demand the absolute best build quality and dealer support, the Stihl RMA 443 TC on the AK 36V platform is in a class of its own.
