Testing & research

We've been testing and investigating products and services for 60 years. Find out more about how we test, and how through continuously questioning the everyday we can tackle consumer detriment

We put more than 3,600 products to the test every year through our test labs, user trials and taste tests, to help you make the right buying decision.

From hidden cameras to fake website listings, we go to great lengths to get to the bottom of a consumer issue.

Find out how we select products and services to test and why we sometimes stop covering these.

Our lab tests and investigations give us independent assessments, but your views are just as important in shaping our work.

From Which? Recommended Provider to Best Buy, we explain the ratings, logos and symbols you'll see on our website.

We work entirely on behalf of you, the consumer. Read our statement of editorial independence.
