Water efficient appliances
The amount of water consumed by dishwashers and washing machines varies greatly. All new dishwashers and washing machines have a European (EU) energy label, which tells you how efficient the appliance is at using water and energy. A is most efficient and G is least efficient, so choosing carefully can save you money, water and energy. You could also:
look for a washing machine that uses less than 50 litres per wash
look for a dishwasher that uses less than 15 litres per wash
try to use your appliances only when full - half load cycles use much more than half the energy and water of a full load
