Put us to the test

Our Test Labs compare features and prices on a range of products. Try Which? to unlock our reviews. You'll instantly be able to compare our test scores, so you can make sure you don't get stuck with a Don't Buy.

Which? Gardening tested 11 compost bins to find the most effective for typical gardeners who want waste to rot down quickly without the hassle of turning their heap regularly. 

We only award Best Buy compost bin status to the bins that produce the best compost and are easy to assemble and use (we look at ease of filling and emptying the bin, and turning the compost).

The table below shows the score for each compost bin we've tested, and how we rate them for various criteria - Best Buys are in red and Don't Buys in grey. If you're not logged in, you'll see all the products listed in alphabetical order.

Members can log in to see the full table of test results, or if you're not a Which? member you can sign up for a £1 trial to get instant access to this and all our other reviews.
