Energy-efficient fridge freezers

A fridge freezer is probably one of the few appliances in your home that uses electricity 24 hours a day, so it makes sense to buy one that's as efficient as possible. Use our energy calculator and recommendations below to buy a fridge freezer that won't rack up your energy bills.
Although fridge freezer energy labels give an indication of which ones are the cheapest to run, our in-depth testing has found that even models that have the same energy label can cost different amounts to run each year.
When we test fridge freezers, we work out exactly how much power every model uses, as well as the likely annual cost it will add to your bills.
But cheap chilling and frugal freezing are only worth having if the fridge freezer can cool quickly and maintain a stable temperature. Otherwise, you may find that you're while you're saving money on your energy bills, you're spending more at the supermarket, because a poor fridge freezer could reduce the lifespan of your food.
Check out our list of the best fridge freezers to help keep your food fresher for longer.

Fridge freezer efficiency tips
- Don’t leave the door open for longer than necessary or the fridge freezer 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 around the compartments, and the appliance will use more energy to keep cold.
Best Buy fridge freezers
When we test fridge freezers, we measure how much energy they use to keep cool, as well as the amount they use up when chilling and freezing fresh items, and we calculate how much they're likely to add to your yearly electricity bills - so you can factor in that cost when you're buying one.
Of course, a great fridge freezer must be able to chill and freeze fast, and stay evenly cool around the clock, even when the temperature in your kitchen changes. To see which models make the grade as the best – and the worst – on the market, head to our fridge freezer reviews.
