Best Cordless Strimmers UK 2026 - Battery Grass Trimmers Compared

A cordless strimmer beats a corded one for most UK gardens because you are not fighting a cable around flower beds, fences and furniture. The Bosch UniversalGrassCut 18V-26 is the best all-round choice for most people: it feeds line automatically, adjusts to your height, and runs long enough to finish a medium garden without swapping batteries. If you already own Ryobi, Makita or Einhell 18V tools, the best pick is the one that shares your existing battery system.

Cordless Strimmers at a Glance

Best Overall: Bosch UniversalGrassCut 18V-26

The Bosch UniversalGrassCut 18V-26 is the strimmer we would buy if we could only pick one. The standout feature is IntelliFEED, an automatic line-feeding system that advances the nylon line as you work. No bumping the head on the ground, no stopping mid-trim to pull out more line. For anyone who has spent five minutes wrestling with a jammed spool, this alone justifies the price.

The telescopic shaft adjusts from 120cm to 140cm, so it fits both tall and short users without hunching. The V-shaped secondary handle keeps your wrists in a neutral position, which matters more than you think after 30 minutes of edging along a 20-metre border.

It runs on the Bosch 18V Power for All system, which covers pressure washers, drills, and garden tools. The included 2.5Ah battery gives roughly 25-35 minutes of continuous trimming, enough for most UK gardens under 200 square metres.

Price: ~£150 with battery and charger. Best for: anyone who wants the least fuss. The automatic feed saves real time over a season.

Best Value: Ryobi OLT1832 ONE+

The Ryobi OLT1832 is the best pick if you already own Ryobi ONE+ tools, or if you want the cheapest entry point into a massive cordless ecosystem. The ONE+ range covers over 200 tools, from drills to workshop saws to garden blowers, and every single one uses the same 18V battery.

The trimmer itself is straightforward: a quick-twist head switches between trimming and edging modes, the boom telescopes from 110cm to 140cm, and the 25-30cm cutting width handles borders and lawn edges without drama. It uses standard nylon line with a manual bump-feed head, which is the one area where the Bosch pulls ahead.

The body-only version costs around £67. With a 2.5Ah battery and charger kit, expect to pay £80-100. If you have a ONE+ battery from a drill or paint sprayer, skip the kit and save the difference.

Price: ~£67 body only, ~£80-100 with battery. Best for: Ryobi ONE+ owners, or anyone building a budget cordless workshop.

Best for Makita Users: Makita DUR181Z

The Makita DUR181Z is the trimmer to get if your workshop already runs on Makita 18V LXT batteries. Makita makes some of the most reliable cordless tools on the market, and the DUR181Z follows that pattern: solid build, bump-feed head that actually works, and a weight (2.3kg) that does not leave your arms aching after the first pass.

The 26cm cutting width sits in the sweet spot for UK gardens, and the adjustable loop handle gives you good control around tight corners and flower bed edges. It is body only, so you need an existing Makita 18V battery or budget for one separately.

Makita batteries are not cheap, but they last. The 3.0Ah BL1830B typically runs this trimmer for 30-40 minutes, which covers most domestic gardens in a single charge. If you already have a Makita angle grinder or drill, you have the battery covered.

Price: ~£75 body only. Best for: anyone already in the Makita 18V LXT system.

Budget Pick: Einhell Power X-Change GE-CT 18 Li

The Einhell GE-CT 18 Li is the cheapest way into a decent cordless strimmer. It uses disposable plastic blades rather than nylon line, which means cleaner cuts on thicker grass and zero spool jams. The trade-off is that you replace the blades when they wear out rather than feeding more line, but a pack of 20 replacement blades costs under £10.

The 24cm cutting width is the narrowest here, which makes it easy to manoeuvre around tight borders and raised beds. The rotatable motor head lets you switch between trimming and edging without flipping the tool upside down. At 2.1kg it is one of the lightest cordless strimmers available.

The Einhell Power X-Change system has over 300 tools in the range, from lawnmowers to workshop equipment. If you are starting from scratch and want the cheapest way into cordless garden tools, this is the one.

Price: ~£65 body only. Best for: tight budgets, or anyone who hates nylon line jams.

Lightest Option: Karcher LTR 18-25

The Karcher LTR 18-25 weighs under 2kg without battery, making it the lightest option in this roundup. If you have a small garden with lots of tight corners, narrow borders, and paths between flower beds, the low weight makes a real difference over a full session.

The twisted cutting line runs at 9,500rpm, which gives a cleaner cut than basic straight-line trimmers. The 25cm cutting width is compact but sufficient for small to medium UK gardens. Karcher also sells this as part of their 18V battery system, which covers pressure washers and garden tools.

The main compromise is power: it handles regular lawn edges and light weeds well, but it will struggle with overgrown patches or thick-stemmed weeds. For a tidy garden that gets regular attention, it is perfectly capable.

Price: ~£70 with battery. Best for: small gardens, or anyone who wants the lightest tool possible.

How to Choose a Cordless Strimmer

The most important factor is not the strimmer itself but the battery system it belongs to. If you already own cordless tools from Bosch, Ryobi, Makita, Einhell or Karcher, buy the strimmer that shares your batteries. A new battery and charger costs £40-80, so a body-only strimmer at £65 suddenly becomes £130 when you factor that in. If you already have the battery, the body-only version is the smarter buy.

Cutting width matters more than most people think. A 25cm head fits comfortably along narrow paths and between fence posts. A 30cm head covers more ground but is harder to control in tight spots. For most UK gardens, 25-28cm is the sweet spot.

Nylon line versus blades is a genuine choice, not a gimmick. Line trimmers are lighter and cheaper but jam on thick weeds. Blade trimmers like the Einhell cut through tougher vegetation cleanly but need blade replacements. If your garden has mostly lawn edges and soft grass, line is fine. If you regularly clear brambles, nettles or thick-stemmed weeds, blades save time.

Battery capacity (measured in amp-hours, Ah) determines how long you can work between charges. A 2.0Ah battery gives 20-25 minutes. A 2.5Ah battery gives 25-35 minutes. A 5.0Ah battery can run for over an hour. For gardens under 200 square metres, 2.5Ah is sufficient. For larger gardens or dense overgrowth, step up to 5.0Ah.

Frequently Asked Questions

What is the difference between a strimmer and a grass trimmer?

They are the same thing. "Strimmer" is a brand name that became generic in the UK, like Hoover for vacuum cleaners. Grass trimmer is the generic term. Both refer to a handheld garden tool that uses a spinning line or blade to cut grass along edges, borders, and tight spots your lawn mower cannot reach.

How long does a cordless strimmer battery last?

Most 18V cordless strimmers run for 20-40 minutes on a single charge with a 2.0-2.5Ah battery. Larger 5.0Ah batteries can push that to 60+ minutes. For a typical UK garden (under 200 square metres), a 2.5Ah battery comfortably handles a full session of edges and borders.

Can a cordless strimmer cut thick weeds?

Line trimmers handle grass and soft weeds easily. For thick, woody weeds like brambles, you need a brush cutter with a metal blade rather than a nylon line. Some strimmers accept blade attachments, but for serious clearing work, a dedicated brush cutter is safer and more effective.

Should I buy a strimmer with a battery or without?

If you already own cordless tools from the same brand, buy the body-only version and use your existing batteries. If this is your first cordless tool, buy the kit with battery and charger. The kit usually saves money compared to buying everything separately.

What cutting width do I need?

25-28cm is fine for most UK gardens with borders and paths. A 30cm+ cutting width covers more ground faster but is harder to manoeuvre in tight spaces. For small gardens with lots of flower beds, stick to 25cm.
