Energy-saving appliances Energy-efficient fridge freezers
Storing fresh food is an energy-intensive task, with fridge freezers using electricity 24 hours a day to keep your groceries cool. Choosing an energy-efficient fridge freezer can make a positive impact on your bills.
Top energy-saving fridge freezers
EU energy labels give a good indication of which fridge freezers are cheapest to run (to find out more read our guide on fridge freezer energy labels). But with all new fridge freezers having to meet at least an A+ rating, it can be hard to choose between models.
Also, while EU energy labels provide a good starting point, Which? tests have found huge differences in the running costs of similar-sized fridge freezers with the same energy label. You can use our fridge freezer energy costs calculator to compare a model’s annual running costs with how much it costs to buy to help you find the best-value fridge freezers overall.
We award our Energy Saver Logo to the Best Buy fridge freezers which are also the most energy efficient. These models are quick to chill and freeze fresh food, maintain a constant temperature inside and have low running costs based on the amount of usable storage space you’re paying to power.
We reveal our pick of the best energy-saving fridge freezers we've tested in the table below. Which? members can log in to see our recommendations. If you're new to Which?, you can sign up for a £1 Which? trial to unlock the table and gain instant access to the rest of our fridge freezer reviews.
Fridge freezer efficiency tips
- Don’t leave the door open for longer than necessary or it will be filled with warm air and have to work to cool down again.
- Avoid putting warm food in your freezer - let it cool down first.
- Keep your fridge freezer at least three quarters full - don’t overfill though, or you’ll stop air from circulating round the compartments and the appliance will use more energy to keep cold.
