Which lawn mower brand to buy in 2022

We survey owners of lawn mowers from the likes of Cobra, Flymo, Gtech, Honda and John Deere to find out the reliable brands that customers are happiest with

Selection of lawn mower brands

Power issues are the most common faults across all lawn mower types, with cordless-mower batteries failing to hold charge, electric mowers suffering electrical failures and petrol-mower engines failing to turn over.

Problems with handle controls breaking are also common with around 10% of reported issues across all mower types – all of which could render your lawn mower unusable until it's fixed.

Knowing which brands develop the most faults and how quickly is vital when buying a new lawn mower. That’s why each year we ask more than 2,000 Which? members to tell us whether they're happy, or have experienced problems, with their lawn mowers in our unique reliability and customer satisfaction survey.

Our survey data takes into account the reported fault rates, the severity of these faults and the speed with which they occurred. In our latest analysis, we've looked at the performance of the biggest manufacturers – including Cobra, Flymo, Gtech, Honda, John Deere – and have calculated a reliability rating and customer score for each, so you know which brands to choose and which to avoid.

Best vs worst lawn mower brands compared

We’ve found huge differences between how satisfied owners are with their lawn mowers.

Our Best Buy lawn mowers will help ensure that you buy a lawn mower that will meet your expectations.

The most reliable lawn mower brands

The table below summarises our latest reliability results. Brands are ranked by their customer score, which relates to whether their customers would recommend that brand. The higher the percentage score for reliability, the fewer the problems reported.

The data is based on a survey conducted with 2,656 Which? members in January 2020. We gathered feedback from 2,656 lawn mower owners on the percentage that remained fault-free after six years and the estimated lifetime in years of each brand and type of lawnmower - cordless, electric or petrol. (-) Brands with insufficient sample sizes not included and the results from corded, cordless and petrol hedge trimmers are combined.

How long will my lawn mower last?

There is some variation among lawn mower types as to the time they last. On average, a cordless mower will last 9.1 years, an electric mower 8.9 years and a petrol mower 11 years. That's according to the experience of Which? members who told us how long they kept their previous appliance from a brand, before they had to replace it, either due to a fault or because it wasn’t working as well as when they first bought it.

As you can see from the results in the table, there’s a big difference between how long the best and the worst lawn mower brands last.

Common lawn mower problems

Although each type of lawn mower is very different in terms of the mechanics that make them run, the most common issues owners of all types of lawn mowers face relate to power outages.

These can be caused by Li-ion batteries in cordless mowers struggling to retain a charge, or by key elements of the engines in electric and petrol mowers rusting or wearing away over time. Moist or cold storage environments can often exacerbate or accelerate these problems.

Thankfully, in most cases these issues are solvable, either by replacing the battery (in the case of cordless mowers) or by having your mower serviced.

Top-three common cordless lawn mower faults

  1. 11% - Battery would not hold charge. Lithium-ion batteries always lose their ability to hold charge eventually. That's why you should always buy a mower with a replaceable battery.
  2. 10% - Battery failed to charge. Correct storage can help extend the life of your battery - remove it from the mower after use and store it in a dry place at a moderate temperature.
  3. 9% - Electrical failure. Key functioning elements may be rusted or worn away. If you aren't confident you can spot what's wrong, it's best to get your mower serviced.

Top-three common electric lawn mower faults

  1. 14% - Electrical failure. The fuse or wiring inside your mower may be damaged - make sure you switch off and unplug your mower before inspecting it.
  2. 11% - Handle controls broke. If the handles are removable, they should be replaceable - but if they're snapped or worn away they probably can't be repaired.
  3. 10% - Blades broke. Replacement blades are widely available to buy for most mowers, and over time they'll eventually need replacing anyway as they will become blunt and rusted.

Top-three common petrol lawn mower faults

  1. 12% - Engine would not turn over. The spark plug might be disconnected, or the air filter in the engine could be dirty or clogged. A routine servicing every two years for your mower should avoid most engine problems.
  2. 11% - Starter rope jammed or broke. Make sure the brake lever, sometimes called the 'dead man's handle', is held down while you pull the cord, otherwise it can prevent the starter rope from being pulled freely.
  3. 10% - Handle controls broke. If the handles are removable, they should be replaceable - but if they're snapped or worn away they probably can't be repaired.

You might expect cheaper lawn mower brands to have the lowest ratings for reliability, but our survey shows that this isn’t always the case. 

The cheapest electric lawn mower brand, on average, in fact scored the highest for reliability and the most expensive brand came bottom of the list for petrol mowers. This proves you don’t always need to pay the highest price for the most reliable lawn mower.

See our Don't Buy lawn mowers to take note of the models you should make sure to avoid.

How we measure faults and reliability in lawn mowers

Our data takes into account minor, major and catastrophic faults:

  • Minor faults don't affect the product's performance significantly, or only occur occasionally with minimal impact. This issue may be irritating or annoying, but isn't frequently problematic and you can easily work around it.
  • Major faults have a noticeable effect on the product’s performance. They affect how you use the product and can be problematic.
  • Catastrophicfaults will render the product unusable, with the fault needing to be repaired or parts replaced before it can be used again.

How we calculate the best and worst brands

Which? has a wealth of information on the UK’s favourite garden product brands. Every two years, we ask Which? members to tell us about the garden products they own - from how likely they would be to recommend a brand, to how reliable the products are once you get them home. This year, almost 5,000 members told us about more than 11,000 products. We calculate a brand's reliability and its customer score based on the results of our bi-annual survey.

Our reliability surveys, combined with our extensive lab tests, mean we can recommend the best lawn mower you should buy.

This data is crucial for our testing, too. If a brand falls far below the category average, we take away the manufacturer’s Best Buy recommendations and won’t recommend any of its products unless a marked improvement in reliability is shown.
