How to use less electricity Buying energy-efficient appliances
Few of us could function without a fridge or washing machine, and that Sunday roast won't cook itself - but there are still ways of cutting back how much energy your appliances use.
Running appliances such as fridge freezers, tumble dryers and washing machines makes up a significant percentage of your bills. In fact, fridges and freezers are the biggest contributors to your home energy bill after central heating - they account for 20% of electricity used in the average UK home.
It therefore makes sense to invest in energy-saving products when you come to upgrade your goods.
Buy energy efficient
Most white goods and common kitchen appliances have an energy-efficiency rating on the label (usually between A and G). Since July 2012, all new fridges, freezers and fridge-freezers must have a minimum rating of A+.
With so many appliances now rated A or above, it can be difficult to decide between them. New energy labels make this clearer, showing each appliance's annual energy consumption in kWh.
Did you know you could save up to £88 a year by choosing the most efficient frideg-freezer?
How much do appliances cost to run?
Appliances can vary a lot in the amount of energy they guzzle. For example, the most energy-efficient fridge-freezer in our tests costs just £14 per year to run. The most expensive to run would set you back £102.
Even models that have the same energy-efficiency rating can have very different annual running costs. Our tests found that two A++ rated washing machines can vary in energy cost by 30%, or £130, over five years. And if you bought your appliances before September 1999, they could have much lower efficiency ratings and guzzle far more energy than they are allowed to today.
Testing energy efficiency
Which? tests appliances to find out how energy efficient they are, so we can show you exactly how much they will cost you to run. We look beyond the energy labels and test appliances the way you actually use them. Then we work out how much they will add to your energy bill.
