products with high total test scores that perform consistently well in
our rigorous lab tests and excel in all key areas.
Energy Savers

products that our testing shows are very energy efficient, meaning
they'll cost you less to run.

The Which? Don't Buy logo alerts you
to the products that performed extremely poorly in one or more key
areas of our tests.

Older models may be harder to track down but you may find a bargain
Launch date
Older models may be harder to track down - but you may find a bargain. Test programmes and key features change over time but we re-evaluate results for older models to make them as comparable as possible with newer models.
Price
We check the availability of Best Buys at major high-street retailers and online. With other models, we show their availability at online retailers (many of these products will also be available in larger high-street chains or at independent retailers).
