We've pulled out our top three impact and roller shredders from our tests in the table below. We also reveal the shredders to avoid.

    A top-of-the-range roller shredder with a turbine cutter, designed to prevent blockages, this powerful machine will make short work of woody and green debris. It's quiet to use and still churns through a hefty amount of material in a few minutes.

    This is a great little impact shredder for lighter loads - it whizzes through material very quickly, plus blockages are easy to clear so won't slow you down too much. The robust temper helps to push softer waste and stray pieces of branch through the machine, and it copes well with soft, fibrous waste such as stringy perennials.

    Despite having a few handy features, this garden shredder disappoints on performance. It's heavy, awkward to move and doesn't do a great job of shredding all the different material in your garden.

Why Which? garden shredder reviews are better

When clearing up garden prunings, you want a reliable and quick shredder that will help you whizz through the job - not one that's constantly blocking up, struggling with certain materials or making a racket. We put garden shredders through their paces in our tough tests so you can choose one that will make your gardening chores that bit easier.

Each shredder has material fed through it for 30 minutes. We rate how easy it is to put branches into the machine, then weigh the material produced to see how much it shredded. We put a variety of garden debris into each shredder to see how good it is with different types of material, including:

  • Straight, fresh branches, up to 20mm in diameter
  • Prunings from an overgrown conifer hedge
  • Spiny and woody branches with side-shoots growing at awkward angles
  • Soft, fibrous plants
  • Dead branches up to the maximum diameter specified for the shredder (typically 30-40mm).

We rate how fine the shreddings are and how much the machine blocked in the process, plus how easy it was to clear out when it did. 

The shredders are assessed for speed and efficiency, as well as noise and vibration, and how easy they are to move and store. 

We also look at overall ease of use as well as safety, so we get an idea of how user-friendly they are for experienced and novice shredder users alike.
