Which? tests reveal cheap to run freezersThree models score top marks for energy use

The latest batch of freezers to hit the Which? test lab show that some models are far more thrifty than others when it comes to electricity consumption.

And it's not necessarily the smallest models that are the cheapest to run, either.

Three of the freezers on test scored top marks for energy use, but one particularly inefficient worktop-height model eats up as much electricity as a full-height model. In this instance, choosing the taller appliance would allow you to freeze twice as much food for the same annual running cost.

You can read our in-depth reviews of more than 170 freezers and fridges, to find out which counter-height, built-in and freestanding models were good enough to be awarded a Which? Best Buy recommendation.

Freezer energy and insulation

All of the models we tested this time have an A or A+ energy label, but we've found in the past that the official energy labels on products aren't always accurate. We run our own energy tests and list the actual running costs for every model we review. 

According to our calculations, an efficient freezer can cost under £20 a year to run.

The best of the current batch of freezers will also keep your food safe for more than 25 hours – provided you can resist the temptation to open the door and take a look inside. A well-insulated freezer will ensure that your food stays safely frozen inside the freezer in the event of a power cut or loss of electricity.

By contrast, food began to thaw in less than 12 hours in the worst performing model, which could make all the difference if you accidentally switch the plug off overnight.

Latest freezers on test

Our latest batch of freezers includes worktop-height models from Bosch, Indesit, Lec, Whirlpool and Zanussi, and tall, freestanding frost-free models from Beko and Frigidaire.
