Dishwashers

Some dishwashers use less water than washing by hand

Not only do dishwashers stop you having to get your hands dirty, but a dishwasher can actually use less water than washing by hand - great news if you're on a water meter. Our table below reveals the energy efficient dishwashers that will also keep your energy bills low.

Using special energy-saving programs, some dishwashers use as little as 6.2 litres of water to wash a full load of 130 items. That’s less than a standard washing-up bowl. But models can vary drastically as to how much electricity they consume.

We've got reviews of more than 400 dishwashers on our website. See the ones that combine great cleaning, with ease-of-use and effective energy saving by checking out all our Best Buy dishwashers.

Top energy-efficient dishwashers

Though most dishwashers are A-rated for energy efficiency, our tests show there can be significant differences in the amount of electricity and water they use - in fact, you could save up to £40 a year on your electricity bill by opting for an energy-saving dishwasher.

We've awarded our Energy Saver logo to models that combine Best Buy performance with low energy and water consumption to help you choose the best model for you.

Falling dishwasher energy use

Back in 2001, our dishwasher tests revealed that the average energy consumption for full-sized dishwashers that hold 12 place settings was 1.42kWh. Today, that amount has been reduced by 13% to 1.23kWh for the same size of dishwasher - that's almost £10 a year.

And if you use your machine's eco program, you'll reduce your energy use by an average of 20% compared to the regular setting.

Dishwasher energy saving tips

  • Use the energy-saving eco program - it may take longer but it cleans plates just as well and uses around 35% less water and 30% less electricity than the main program.
  • Don’t pre-rinse or soak your plates before putting them in the dishwasher - this wastes water.
  • Fully load your dishwasher - they're most efficient when they're full. In fact, similar amounts of water get used no matter how many items are in there, so you may as well make the most of it.
