Most and least reliable grass trimmer brands

We survey thousands of Which? members to find out which brands of grass trimmer are reliable. We ask members if their grass trimmers have developed any faults, what these faults are, and how long before they occurred. From this, we're able to answer definitively which brands you should choose and which you should avoid. 

Grass trimmers generally suffer from a great number of faults, particularly line-feed problems, and this is why the reliability score is so low overall. However, some brands score much more highly than others.

The table below reveals reliability ratings for a range of popular electric, cordless and petrol strimmer brands, based on the experiences of more than 1,000 grass trimmer owners. Our unique reliability ratings show at-a-glance how the brands of grass trimmer stack up against one another for reliability.

How grass trimmer brands compare

Several manufacturers make more than one kind of grass trimmer: electric, cordless or petrol. However, different brands top each category, and we have found this as well with our best grass trimmers.  

The most reliable grass trimmers seem to be cordless ones. However, cordless grass trimmers have typically been owned for only four years compared to six years for electric grass trimmers and eight years for petrol models. 

Many grass trimmers score poorly in our survey as they suffer from one very common fault: line-feed problems. Around two thirds of electric grass trimmer owners complain about the line-feed mechanism jamming, but only one third of cordless grass trimmer owners and half of petrol grass trimmer owners. To find out how to combat this, read our guide on how to avoid line-feed problems

This may be down to the amount owners are willing to pay for these tools. Which? members tell us they spend far less on electric grass trimmers than on cordless or petrol models. In our tests we have found grass trimmers that only cost £20-£30 do not give good value for money. 

Common grass trimmer problems

  • Line feed jams 48%
  • Line breaks easily 37%
  • Hard to replace line 32%
  • Not enough line fed out 27%

Through our survey we have seen just how many people find grass trimmers frustrating to use thanks to problems with the line feed mechanism. This can turn what should be a quick job into a much more lengthy task. 

Cordless grass trimmers often had battery problems as well, with a quarter of owners telling us their batteries would not hold charge.
