An energy-efficient fridge freezer can help cut your bills
After central heating, cooling appliances like fridge freezers are the biggest contributor to your energy bill because they’re left switched on round the clock. 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 keep 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. The most efficient models are rated A++.
To comply with new EU energy efficiency targets, manufacturers voluntarily removed all models from the market that rated less than A in July 2010. From July 2012 this will extend to models rated less than A+. However, if your last fridge freezer was bought before September 1999, it could be anything up to a G rating, with no limit on how much energy it uses.
