Which? tests

We base most of our product recommendations on lab tests, because we believe it’s the best way for you to know how a product performs before you buy it.

Our tests find you the best

We test products in the lab for how you'd use them in real life, and we test thousands every year - from smartphones to mattresses, washing machines to pushchairs, coffee machines to car seats and everything in between.

Know how products perform

In a world awash with fake reviews and product misinformation, our tests find you the facts and our reviews tell the truth. This means you choose a product with confidence, and we don't want you wasting time and money on products that don't cut it.

We're 100% impartial

We buy pretty much every product we test so our recommendations can't be swayed by third parties, and we use the same consistent tests for each particular category of products. You can trust our product reviews because they're based on our independent test results.

We're proven test experts

We've been testing, reviewing and recommending products for more than 60 years, so you can be confident that we know exactly what we're doing.

We make choosing easier

Our test results and overall scores make it easy for you to see at a glance how a product performs, so you can readily separate the good products from the bad, and the bad from the downright dangerous.

Our recommendations

Choose a Which? Best Buy - it's a high scorer in our tests and we recommend it with confidence. But before you buy, read the full review and check the test results so you know it's the right product for you.

Our warnings

Avoid any product that gets our Don't Buy verdict - our test results tell us it's not up to the job. Products that do well in some of our tests but fail our safety tests automatically get our Don't Buy verdict because we want you to stay safe.

Stay safe - when we find an unsafe product we tell you why, and we go public with our warning.

Be aware - we point out the brands that should be taking product safety more seriously.
