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.

Your fridge is using electricity 24 hours a day, so it's a good idea to buy an energy-efficient model if you want to keep running costs as low as possible. Use our energy calculator and recommendations below to pick out a fridge that won't drive up your energy bills.

Refrigeration appliances notch up a staggering £2bn in electricity bills each year in the UK because they're switched on around the clock.

And although all new models must have an energy label rating of at least A+, we've found that models with the same energy label can cost different amounts to run each year. Our rigorous expert testing calculates the true running costs of every fridge we review.

See our energy calculator and table below to find your perfect energy-efficient fridge.

To see the top-scoring models that excel at the main task of chilling, take a look at our Best Buy fridges.

We give star ratings to all fridges based on their energy efficiency. But the best fridges are also able to chill cheaply and quickly, to help keep your food fresher for longer. The five fridges we've selected below are cheap to run, but also performed well in our tough performance tests, which could mean you waste less food and save money at the supermarket, too.

Built-in fridges tend to be more expensive than freestanding models - the average price of the tall built-in fridges we’ve reviewed is around £600, and we haven’t tested any that cost less than £300. That means this built-in Best Buy is cheaper than most to buy, and it’s even more economical when you consider lifetime costs, because it’s very energy efficient for its size. It performed well in our tough chilling tests and it’s very quiet as well, so you’ll definitely want to consider it if you’re looking for a tall, integrated fridge.

You’ll struggle to find a more energy-efficient fridge than this one. Even though it will be working to chill your food all day every day, you’ll hardly notice the effect on your electricity bills. It just missed out on a Best Buy because the temperature can fluctuate when the outside temperature rises. However, if you’re looking for an economical small fridge, you should still consider this one as it did well in our crucial chilling speed test.

Fridge energy-efficiency tips

  • Don’t leave the door open for longer than necessary or the fridge will be filled with warm air and have to work to cool down again.
  • Defrost frozen food in your fridge - it acts like an ice pack to help cool the fridge, meaning that your fridge uses less electricity.
  • Avoid putting warm food in your fridge - let it cool down first.
  • Clean the condenser coils at the back or underneath your fridge - thick dust can reduce their efficiency by up to 25%.

Best Buy fridges

When we test fridges, we measure how much energy they use to chill and to keep consistently cool. We then work out how much each model will add to your yearly energy bills and calculate whether it's pricey to power for the amount of food you can actually fit inside. 

The best fridges use energy sparingly, working out as ultra-cheap to run for their size.

Of course, it's essential that a fridge is good at its core task of chilling food, so we investigate how quickly each fridge can chill (speedy cooling helps keep your food fresher for longer) and whether it can keep evenly cool during both scorching summer and chilly winter months.
