Freezers: Freezer energy costs

Freezers, along with other domestic cooling appliances, use the most electricity of all appliances in your kitchen because they are left switched on around the clock.

So the energy running costs of a freezer can really affect how much it will cost you over its lifetime. One that’s cheap to buy but costly to power could work out more expensive in the long run than a model that’s more expensive to buy but has lower running costs.

We have created the running costs tool below to help you work out how much a freezer will cost to run – and once you checked the cheapest to run using our tool below, head to our full freezer reviews area for reviews and more buying advice.

Energy-efficient freezers

Which? Best Buy freezers are fast at chilling food and keep a constant temperature throughout – even if your kitchen temperature changes. The most energy efficient freezers we find are awarded our Energy Saver logo – these models are Best Buys whose energy use is in the top 20% of models we have tested.

All freezers have EU energy labels which help you to see at a glance which models are more energy efficient. All new freezers must be rated A+ or above but if you have an old appliance it could have a power-hungry G rating – with no limit on the electricity it uses.

But the ratings don’t tell the whole story – and they don’t reveal how much a freezer will cost you to run. Only Which? tests can tell you exactly how much a freezer will add to your electricity bill.

An energy efficient freezer with low running costs won’t save you money if it breaks down after a few years. The cost of repairing or replacing it will soon outweigh any savings. Choosing a reliable freezer is important so we’ve built freezer reliability profiles of the top 20 brands – including Bosch, Beko and Hotpoint – based on the experiences of thousands of Which? members.
