Consumers could save hundreds of pounds thanks to a new label that will show how much electricity everyday appliances use over a lifetime.
The Department for Energy and Climate Change (DECC) and John Lewis will introduce a product-labelling trial next year that shows the lifetime running costs of household appliances.
For example a fridge freezer could cost an extra £500 to run over ten years but a more efficient model will cost just £350.
Trials in Norway have shown that when consumers see the running costs as well as the initial cost of a product they are more likely to buy energy efficient models – and save money over the long term.
John Lewis will roll out the trial in their shops from next year, beginning with washing machines, washer dryers and tumble dryers.
It is estimated that the more efficient models could cost up to £900 less over a lifetime.
