Energy Ratings
The more energy efficient an appliance is that you buy the more money you can save in the long run, whilst helping the environment. Energy efficiency doesn't mean you have to compromise on performance.
Energy consumption and running costs
This shows how much electricity is used under standard operating conditions, measured in kWh / year "kilowatt hours" for refrigeration or kWh/cycle for washing and other appliances.
You can work out the average annual running cost and saving by multiplying the KWh consumption figure by 9p (which is the average unit price of electricity - your actual savings will depend upon the exact consumption figure).
Performance in other areas
Laundry and dishwashing labels also have ratings for washing, spin and / or drying performance. The A-G indicators here are similar to the main efficiency ratings, and are based on standard industry testing - the test cycle used is on the label. ("A" rating is the best).
