Chest freezers are invaluable when it comes to freezing large amounts of food. While the best chest freezers we've tested are reliable and easy to clean, the worst are slow to freeze, which means vital nutrients from food could be lost. We also have safety concerns with certain chest freezers.

If a lack of storage space is stopping you from taking advantage of BOGOF offers at the supermarket, a chest freezer will help. With a chest freezer, you can buy in bulk from the butchers and still have room for large loads of fresh produce.

Keep scrolling for more details on the best chest freezers to pass through our test lab. Each one has scored well for freezing speed, temperature stability and energy use.

Top 5 chest freezers


This is our best chest freezer on test. There's a respectable 98 litres of space on offer (equal to 5 supermarket bags), and it's also one of the fastest we've seen - it gets down to a safe temperature in lightning-quick time.


Small but powerful, this impressive chest freezer sailed through out tough tests. Its ability to maintain a stable internal temperature, whatever the conditions outside, is particularly impressive. It's well-priced and is energy efficient, too.


Worth considering if you want a mid-sized chest freezer that doesn't cost a fortune, this model scored well in our lab. With 197 litres of space inside (equal to around 10 supermarket bags), it's energy efficient (running costs are low) and should keep your food perfectly preserved.


This chest freezer ticks all of the important boxes: it keeps food perfectly preserved in changing room temperatures, it does a decent job of freezing fresh food, it's cheap to run for its size, you can rely on the recommended thermostat setting to create perfect freezing conditions. It doesn't come cheap, though.


This chest freezer does what you need it to do: it keeps food consistently frozen, until you're ready to defrost it. It's also cheap to run and keeps food shielded from the thawing effects of a power cut for ages.

Chest freezer safety concerns

At Which? we aim to recommend the best products for you to buy. With this in mind, we continually monitor and vary the assessments that underpin our reviews to take account of changing standards and areas of concern. 

Our tests have revealed that plastic backing can be highly flammable. We are therefore not recommending any refrigeration appliances that have flammable plastic backing.  

All our freezer reviews highlight the type of backing each model has.

How to buy the best chest freezer

Our tests prove that spending big on a new chest freezer doesn't always guarantee you a great product. When shopping for a new chest freezer, keep an eye out for these key features:

  • Storage baskets Handy for storing open packets of food, these hang above the snacks at the bottom of your chest freezer.
  • Counterbalanced lid This will save you from propping up the lid of the freezer while you're digging around for food.
  • High temperature warning Some chest freezers will warn you when there's a drastic change in temperature due to a fault.
  • Lock If you keep your chest freezer in your garage, a lock will keep your food safe.
