Energy-saving appliances: Energy costs calculators

  • Use our energy costs calculator to find the cheapest-to-run home appliances
  • Our in-depth testing shows you the most - and least - energy-efficient products
  • Includes fridge freezers, dishwashers, washer-dryers and more

Our energy running cost tools will help you work out how much an appliance will cost you to run over its lifetime, so you can buy energy-efficient products that won't drive up your bills.

How much do you think your fridge or dishwasher is costing you to run every year? The answer is probably more than you think - especially if the appliances you own are old or not very energy efficient.

If you’re planning on buying a new appliance, it’s not just the upfront price you should consider, but also the cost of running it. That's why we've created calculators that reveal the electricity costs of all the dishwashers, refrigeration products and washer-dryers that Which? has tested, so you can compare how much different models will add to your energy bills.

Our easy-to-use energy cost calculators allow you to search and compare different models so you can find the cheapest option for you.

We've created cost calculators for all of the biggest domestic energy guzzlers:

Once you've identified a cheap-to-run appliance or TV, Which? members can log in to see how it was rated by the experts in our independent lab tests. If you're not already a Which? member, you can sign up for a £1 Which? trial to get instant access to all our reviews and advice.

Save energy, save money

Did you know?

  • Annual fridge freezer running costs can vary by £47 a year, depending on the model you buy.
  • You could be £40 a year better off if you choose the most energy-efficient dishwasher over the least efficient.
  • Our tests have found that the annual running costs of washing machines can vary from £24 to more than £100.

Differences in running costs can be so great that sometimes a pricier model that's more energy efficient can work out cheaper to own in the long run than an energy guzzler that costs less to buy.

For example, the Zanussi ZDS2010 dishwasher costs £330 to buy and £56 a year to run. Over a lifetime (seven years) it costs £722.

Now compare that to another freestanding slimline dishwasher, the Beko DSFS6831W, which you can buy for £206 and will leave bills of only £33 a year. That's a lifetime cost of £434 - £288 less than the Zanussi.
