Top five freezers for 2020

By Patrick Gallagher

Whether you’re looking for a tall freezer, a small freezer or a chest freezer, our round-up of the top five on test will help you find the best.

Put us to the test

Our Test Labs compare features and prices on a range of products. Try Which? to unlock our reviews. You'll instantly be able to compare our test scores, so you can make sure you don't get stuck with a Don't Buy.

The best freezers will freeze food quickly to keep it in the best condition, and are cheap to run. The worst we've seen are sluggish at freezing, can guzzle energy, and be a pain to use and keep clean.

Whether you tend to buy frozen food, freeze fresh food or do a bit of both, you want whatever you put in the freezer to come out in the best possible condition. Food needs to be kept below -16°C to preserve it, and the quicker it gets down to that temperature the better.

When the best freezers cool more than twice as quickly as the worst in our tests, it’s easy to see which are likely to keep your food as nutrient-rich as possible and give you better value for money.

Fire-risk freezers and safety

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.

Best tall freezer


Quite simply, this freezer is one of the best we’ve ever seen. It’s lightning-quick to cool and it never fails to stick to a safe and steady temperature, regardless of whether the room temperature rises or falls. It’s also very spacious and extremely efficient for its size, so it won’t cost the earth to run. The only slight flaw is that it’s a bit of a chore to clean.

Best small integrated freezer


We tested this freezer several years ago, so the results aren't directly comparable with the other freezers on this list, but don't let that put you off. This is still the best small integrated freezer we've seen. It didn't do poorly in any of our tough tests and it particularly impressed in our energy efficiency and temperature stability tests.

Best tall integrated freezer


It may be among the most expensive freezers we've tested, but it's also one of the most efficient, so you'll be doing your bit for the environment if you invest in it. You'll also be getting an exceptional freezer that didn't do poorly in a single one of our tough tests and will help to preserve your food in great condition.

Best cheap freezer for your garage


This tall freezer is a bargain, not least because it’s one of very few freezers available that’s designed to work in a garage. It didn’t do poorly in any of our tough tests and we were really impressed by how little the temperature fluctuated inside when we changed the room temperature. It’s frost-free, too, so you’ll never need to defrost it by hand.

Best chest freezer


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.

Which? freezer reviews

Not only do we test freezers more rigorously than anyone else, but we’re completely independent, too, so you can have complete confidence in our test results.

While fast freezing is the most important factor we look for, it takes a lot more than that to become a Best Buy. We also test how much the temperature in the freezer fluctuates when the room temperature changes, as well as how effective the manufacturer’s-recommended thermostat setting is at getting the freezer down to the perfect temperature.

When you add our energy efficiency, noise and ease-of-use tests to the mix, you can see that we do everything we can to wheedle out the best freezers money can buy.
