Don’t Buy freezers are slow at cooling, power-hungry and can’t keep a stable temperature when the room temperature fluctuates.

Our expert and independent lab tests expose the Don’t Buy freezers that will leave you with food that isn’t as fresh and nutrient-rich when you come to defrost it.

Don’t Buy freezers are everything a good model isn’t. They take ages to freeze fresh food, can’t keep a stable temperature inside the freezer when the room temperature outside changes, and are difficult to use. They’re power-hungry, too, so even though the freezer might cost less than others upfront, you’ll pay the price over its lifetime in higher energy costs.

Our lab tests will help you to avoid these substandard freezers. You can use our expert reviews to choose a model which chills quickly and won’t cost a lot to run.

Finding a freezer that is great at its job can be tricky, but our tests have uncovered some fantastic freezers that won't leave you out of pocket or disappointed.

Every year, we test and review the latest freezers from all the big brands, including Samsung, Hisense, Hotpoint and John Lewis. We don’t want you to end up with a shoddy appliance, so our lab experts put freezers through an exhaustive series of tests, including investigating how effective and quick each model is as freezing, and how energy efficient they are. 

All our tests go towards calculating the Which? test score. There's no room for unconscious bias, so you can trust our results and easily compare the best and worst freezers. We're not influenced by third parties and we don't accept freebies from product manufacturers or retailers. We buy all the products that we test ourselves, so our advice helps you to make the right choice first time and avoid costly mistakes.
