All hedge trimmers are tested in the same way, so that we can get a proper comparison between models. First, we start by unpacking and, if required, assembling each model. While this job may only need to be done once, it’s essential to understand how easy (or not) a trimmer is to get started with.

For battery-powered hedge trimmers, we ensure that the batteries are fully charged before we start work, using the size of battery recommended by the manufacturer.

Handling is essential for all hedge trimmers, so our reviews tell you how well balanced each model is, how comfortable the controls are, and how easy the trimmer is to move. We test cutting at different angles, the tops of hedges, and we test how far we can comfortably reach with each trimmer.

To test performance, we cut sections of different types of hedges and growth, including box hedging, conifer, trailing ivy, and thick blackberry brambles. With each hedge trimmer, we note how easily it cuts through each type of growth and the thickest diameter branch it can cut through.

For battery-powered hedge trimmers, we use them until the batteries run out, to tell you how far they can cut on a charge. And, we tell you how long each battery takes to recharge.
