Energy saving dishwashers
When we test and review dishwashers we calculate the annual energy running costs – as well as how good they are at getting your plates sparkling clean – to make it easy for you to identify the cheapest-to-run machines.
Although most dishwashers have an official A-rating for energy efficiency, We test of hundreds of dishwashers we've have found significant differences in electricity and water use.
Which? gives each model a star rating of one to five for energy and water use. The most inefficient dishwasher we've tested would add £72 to your yearly energy bills, while the best just £32.
Look out for dishwashers with a Which? energy efficiency rating of four stars or more.
