An energy-efficient fridge freezer can help cut your bills
After central heating, cooling appliances such as fridge freezers are the biggest contributor to your energy bill because they’re left switched on all the time. Choosing an energy-efficient model can help reduce the impact of these appliances.
Top energy-saving fridge freezers
Energy labels give a good indication of which models are cheaper to run than others, but they won’t tell you how much you'll actually pay to power your fridge freezer. As part of our in-depth fridge freezer testing, we calculate exactly how much electricity each model uses and how much it will add to your energy bill. Our fridge freezer energy costs calculator reveals exactly how much each model costs to run.
We also award our Energy Saver logo to the Best Buy fridge freezers that are also the most energy efficient. These models are quick to chill fresh food and will maintain a constant temperature if your kitchen heats up or cools down. They also have low running costs based on the amount of usable storage space you’re paying to power.

Fridge freezer energy efficiency
Every fridge freezer you see in the shops will have an energy label and rating to indicate how energy efficient it is – find out more in our fridge freezer energy labels guide. The most efficient models are rated A+++.
To comply with new EU energy-efficiency targets, manufacturers stopped making models rated lower than A+ in July 2012. However, if your last fridge freezer was bought before September 1999, it could have anything up to a G rating, with no limit on how much energy it uses.
