Energy-efficient fridges

Want a fridge that's cheap to run? We've rounded up the Best Buy fridges that will help you save on your energy bill.

Your fridge is using electricity 24 hours a day, and so to keep running costs low it's a good idea to buy a fridge that's energy efficient. 

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+, our rigorous expert testing calculates the true running costs of every one.

See the table below for our pick of the best energy-efficient fridges around.

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

Cheap-to-run fridges

We give star ratings to all fridges based on their energy efficiency. Best Buy fridges that also have low energy running costs compared with their size are awarded our prestigious Energy Saver logo. You can click the ‘Energy Saver’ box when you compare fridge features and prices to filter your results so they only contain top-performing, eco-friendly models.

Fridge energy-efficiency tips

  • Keep your fridge at 0-5°C and use a fridge thermometer to check your thermostat is accurate. Lower temperatures increase energy use but your food will spoil if it’s too warm.
  • Defrost frozen food in your fridge - it acts like an ice pack to help cool the fridge, meaning that your fridge uses less electricity.
  • 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.
