The overall Which? test score is made up of the following star ratings, all determined by our rigorous lab tests.

How we test fridges

14 May 2025

Cooling power

How we test cooling power

We test cooling power by seeing how quickly a fridge chills, as the faster food cools the longer it will last, the more nutrients it will retain and the less chance there is for harmful bacteria to thrive.

Accuracy of thermostat setting

How we test accuracy of thermostat setting

To see whether you can rely on a fridge's thermostat to create perfect temperatures for storing chilled food, we set the fridge up following the manufacturer's recommended thermostat setting. Models scoring five stars have reliable thermostats that are spot on, whereas for models scoring two stars or less you would need to set the temperature using a separate fridge thermometer.

Energy efficiency

How we test energy efficiency

How energy-efficient the fridge is for the amount of usable space it offers. Fridges are switched on 24/7, so it's important to choose one that won't cost a fortune to run. The best fridges score four or five stars and use a minimal amount of energy to cool food. You can spot the real energy guzzlers as they're awarded a poor one or two stars in this test.

Quietness

How we test quietness

We assess how noisy each fridge is when the compressor's running and when it switches on and off.

Ease of use

How we test ease of use

To see whether a fridge is easy to use, we rate aspects such as how sturdy the shelves and drawers are, how smoothly the drawers slide in and out, whether there are enough door racks and shelves for the size of the fridge, whether the fridge is easy to programme and whether the thermostat is easy to adjust.

Ease of cleaning

How we test ease of cleaning

We spray cherry juice inside each fridge, let it dry to a sticky mess and then rate how easy it is to clean, to see how likely food and drink spills are to seep into hard-to-reach spots and crevices.
