Understanding What You Are Actually Paying For
Before diving into models, it helps to know what drives cost in a lawn mower. Three things matter: the power source, the cutting width, and the build quality of the deck.
Corded electric mowers remain the most affordable category. Which? testing has found capable corded models selling for between £120 and £150, with some Best Buys dipping below £100 during seasonal promotions. They plug into the mains, weigh less than their petrol cousins, and require almost no maintenance beyond blade sharpening. The trade-off is the cable, which limits range to roughly 30 metres from a socket unless you invest in an outdoor-rated extension lead. For the typical British terraced or semi-detached garden, however, this is rarely a real constraint.
Cordless mowers have dropped in price significantly over the past few years. BBC Gardeners' World Magazine's 2026 review roundup found well-rated models under £300, with the Ryobi RLM18X33B50C (£220) and Einhell RASARRO 36/34 (£284) both earning strong scores from their testing panel. Battery technology has improved enough that even entry-level cordless mowers can now handle 250 to 350 square metres on a single charge, covering the vast majority of UK gardens.
Petrol mowers sit at the higher end. They make sense for lawns above 400 square metres, or for anyone dealing with thick, damp grass on uneven ground. Prices for a dependable petrol model from brands like Mountfield or Hyundai tend to start around £350 and climb quickly. For most suburban gardens, they represent overkill.
A Closer Look at Budget-Friendly Models
The Bosch Rotak range has become something of a default recommendation in the UK affordable mower space, and with reason. The Bosch Rotak 34R, widely available from retailers like B&Q and Argos, typically sells for around £130. Its grass combs, small plastic prongs at the front edge, pull upright the blades of grass along borders and fences that most mowers miss. The 40-litre grass box is generous for a machine of this size, meaning fewer trips to the compost heap.
The Flymo EasiStore 340R offers a different approach. At around £120, it features a collapsible handle that lets the whole unit fold vertically for storage. If your shed or garage already competes for space with bicycles and camping gear, this design matters. Flymo, a brand with deep roots in the UK, also produces hover mowers like the EasiGlide 330V, which float on a cushion of air and make light work of slopes. These tend to cost under £100, though grass collection on hover models can be patchy.
McGregor, a brand sold through Argos, sits at the very bottom of the price ladder without tipping into disposable territory. Their 34cm corded rotary mower can be found for around £90, and a bundled set including a grass trimmer adds only about £30 more. These are simple machines with fewer features, but for a small, flat lawn they do the job.
For those who can stretch towards £250, the Worx WG743E.1 impressed IndyBest reviewers with its cut-to-edge design, which positions the blade off-centre to reach closer to borders and reduce the need for follow-up strimming. Seven cutting height settings let you handle both the first spring growth and the tighter summer trim with one machine.
| Model | Type | Typical Price | Cutting Width | Best For | Strengths | Limitations |
|---|
| Bosch Rotak 34R | Corded Electric | £130 | 34cm | Small to medium lawns | Grass combs, 40L box, reliable brand | Corded range limited |
| Flymo EasiStore 340R | Corded Electric | £120 | 34cm | Small lawns, tight storage | Vertical folding, lightweight | Basic features |
| Ryobi RLM18X33B50C | Cordless | £220 | 33cm | Medium lawns | Battery included, lightweight | Single battery runtime |
| Einhell RASARRO 36/34 | Cordless | £284 | 34cm | Medium lawns | Ease of use rated highly | Higher upfront cost |
| McGregor 34cm 1400W | Corded Electric | £90 | 34cm | Small flat lawns | Very low price | Fewer features, basic build |
| Worx WG743E.1 | Cordless | £250 | 40cm | Medium lawns, neat edges | Cut-to-edge design, 7 heights | Slightly heavier at 13.9kg |
| Hyundai HYM 480 SPER | Petrol | £505 | 48cm | Large lawns | Self-propelled, powerful | Heavy, needs fuel storage |
Where British Shoppers Actually Buy
Argos, B&Q, and Homebase form the high-street backbone of lawn mower retail in the UK, each offering click-and-collect and home delivery. Screwfix carries brands like Greenworks and Hyundai, with free standard delivery on orders above £50. For a wider selection, specialist online retailers such as MowDirect and World of Mowers stock dozens of brands and often run seasonal discounts that undercut the generalists.
Timing matters. Prices tend to dip in late summer, around August and September, when retailers clear stock ahead of autumn. Spring, by contrast, sees demand peak and discounts thin out. If your current mower can limp through one more season, buying in late summer can save 20% or more on the same model.
Tom, a homeowner in Leeds with a 160-square-metre lawn, replaced a temperamental petrol mower with a cordless Ryobi last year. His local B&Q had a display model at £190, and he has not looked back. The silence of the electric motor means he can mow on Sunday mornings without annoying the neighbours, and the absence of petrol fumes and pull-cord frustration has turned a chore into something closer to pleasant.
What to Check Before You Buy
Cutting width deserves more attention than it gets. A 32cm mower on a 200-square-metre lawn means more passes and more time. A 40cm model cuts that time noticeably. The trade-off is storage: wider mowers take up more shed space and feel heavier to push. For most UK gardens between 100 and 250 square metres, a 34cm to 37cm width hits the balance.
Grass collection boxes vary hugely. A 30-litre box on a medium lawn will have you emptying it every few minutes, which grates. Look for 40 litres or above if your lawn is larger than a badminton court. Some models now include mulching plugs that chop clippings finely and return them to the soil as natural fertiliser, eliminating collection altogether.
Warranty length signals how much a manufacturer trusts its own product. Bosch and Hyundai typically offer two to three years on their mowers. Ryobi provides three years on many cordless models when registered online. A longer warranty on an affordable mower suggests the internals, particularly the motor, are built to last beyond the first season.
Blade quality separates a satisfying cut from a ragged one. Pressed steel blades are standard on budget models and work fine if sharpened annually. Forged or hardened steel blades hold their edge longer and produce a cleaner cut that leaves grass less vulnerable to disease, though they add to the cost. A local mower service shop can sharpen blades for a modest fee, usually within a day or two, and this single act of maintenance transforms the performance of even the cheapest machine.
For those with sloped gardens, common in parts of Wales, Scotland, and the Pennines, a self-propelled mower removes the physical strain of pushing uphill. These add roughly £50 to £100 to the price of an equivalent push model. The Hyundai HYM 480 SPER, while at the upper end of the affordable bracket at around £505, offers self-propulsion and a wide 48cm cut for larger sloping lawns.
A Few Words on Robot Mowers
Robot mowers have crept into the affordable conversation. The Yard Force EasyMow 260B sells for around £400, and while that is hardly pocket change, it undercuts most competitors by several hundred pounds. These machines suit regular, uncomplicated lawns without too many obstacles. Installation involves laying a boundary wire, which takes an afternoon. Once set, they maintain the grass at a consistent height with almost no human involvement. For anyone with mobility challenges or simply a strong dislike of mowing, the time saved may justify the higher initial outlay.
Corded electric mowers remain the practical default for most British households. They are light enough to carry up steps, powerful enough for damp grass, and cheap enough that replacing one after five or six years does not sting. Cordless models have closed the gap in both price and performance, and for gardens under 300 square metres they now make a compelling case. Petrol still has its place for the largest lawns, but the maintenance, noise, and emissions push it out of contention for the average suburban plot.
A good lawn mower is the one that fits your garden, your storage, and your patience for maintenance. The British market offers genuinely capable options under £150, and spending more than £300 should only happen if your lawn size or terrain genuinely demands it. Visit a local stockist, feel the weight of the machine in your hands, and check the grass box clips and height adjustment levers before committing. A machine that is awkward to adjust or empty will gather dust in the shed regardless of how well it cuts.
