Cracked or broken drawers and flap lids, a build up of ice in a frost-free model, and not maintaining the correct temperature are some of the most common freezer faults, according to our survey of nearly 2,400 owners.
Worryingly, we also found catastrophic faults, such as a broken compressor, are far more common in some freezer brands than others. For the very worst brands, 10% develop a fault within the first year of use.
Knowing which brands develop the most faults, and how quickly, is vital when you're buying a new freezer. That's why we asked nearly 2,400 Which? members to tell us whether they are happy, or have experienced problems, with their freezer in our unique reliability and customer satisfaction survey.
Our survey data takes into account the reported fault rates, severity of these faults, and the speed with which they occurred. In our latest analysis we've looked at the performance of the biggest freezer manufacturers – including Beko, Hotpoint, Indesit, John Lewis, Miele and Samsung – and have calculated a reliability rating and customer score for each so you know which brands to choose – and which to avoid.
As you can see, there's a big difference between the most and least reliable freezer brands, and the satisfaction score reported by customers.
The table below summarises the reliability results. Brands are ranked by their customer score, which relates to whether their customers would recommend it. The higher the percentage score for reliability, the fewer problems reported.
But bear in mind that a freezer can be reliable without being safe. Some brands in the table below are still selling freezers with flammable plastic backing. Every model with this type of backing has been made a Don't Buy, regardless of how it performed in our freezing tests, because our research reveals that flammable plastic-backed freezers can dramatically accelerate the spread of flames in the event of a fire. While the use of flammable plastic-backing is legal and the risk of fire remains low, we think all freezers should have flame-retardant backs. Find out more about .

The most common problem people experience with their freezer is cracked or broken drawers or flap lids.
Other common problems include a build up of ice in a frost-free model and a freezer not maintaining the correct temperature, each accounting for 14% and 10%, respectively, of all the freezer faults reported in our survey.
The graph above shows how the freezer brand that stays free of faults for longest compares to the worst brand and the overall average. Which? members can see how brands compare for faults over an eight-year period in the table below.

Our reliability score takes into account minor, major and catastrophic faults:
Which? has a wealth of information on Britain's favourite appliance brands. Every year we ask Which? members to tell us about the home appliances products they own – from how likely they would be to recommend a brand, to how reliable the products are once they get them home. This year nearly 10,000 Which? members told us about more than 34,000 devices. We calculate a brand's reliability and its customer score based on the results of our annual survey.
Our reliability surveys, combined with our extensive lab tests, mean we can recommend the best freezers you should buy.
This data is crucial for our testing, too. If a brand falls far below the category average, we take away the manufacturer’s Best Buy status and won’t recommend any of their products unless a marked improvement in reliability is shown.
