Hedge trimmers should take the hard work out of cutting your hedge. But we've found some that don't have the power to cut through even thin branches, leaving you with a messily-cut hedge. Find out how our expert lab tests separate the hedge trimmers you should avoid from those recommended as Best Buy hedge trimmers . 

Join Which? to find out which hedge trimmers we've named as Don't Buys.

Hedge trimmers are designed with one simple job in mind - to cut through a hedge quickly, efficiently and neatly. But we see too many hedge trimmers that either can't cut even the thin stems of a hedge or take a very long time to do this. On top of this, too many are awkward and uncomfortable to hold, or heavy and noisy. 

On the plus side, we've also found many hedge trimmers that make light work of even tough hedges with thick branches. They have the power to cut through stems rapidly, meaning you spend less time cutting your hedge. They also cut cleanly, leaving your hedge looking neat and reducing the risk of disease entering through the cut stems. 

We've tested all the most popular hedge trimmers, including models from Bosch, Black & Decker and Stihl, to help you find the best one for your garden. Our rigorous tests mean we can recommend hedge trimmers that will cut quickly and efficiently, leave a neat finish and be a joy to use.
