Best Energy Efficient Standard & Slimline Dishwashers 2023.

Posted by Lorraine on 27th Mar 2023

Are you looking for a new dishwasher? Struggling to work out which is the most affordable option when it comes to running costs? We're here to help!

Finding a balance between the initial cost of the appliance and energy efficiency is important. Trusted, quality brands bring extra peace of mind and, for some, paying a little more for a brand they trust outweighs other factors.

All the dishwashers we have chosen include an eco setting and the figures are based on using the eco programme. Did you know that using an eco cycle to wash dirty dishes can save around 20% energy.

Be mindful of your needs. Do you often fill a dishwasher? Do you plan to load large dishes and delicate glass wear in the dishwasher? Questions like these will help you determine what you need from your dishwasher. Full Size Dishwashers are 600mm wide and are actually more economical to run as they can clean more place settings in one go making them a great choice for families. If you live alone or have limited space in your kitchen, a slimline dishwasher is a good option.

To help you find a good energy efficient dishwasher to suit your budget and requirements, we've picked a small selection of dishwashers that vary in price and efficiency. We've compared efficiency ratings, capacity, water usage and more for both full size and slimline models.

One Place Setting Includes (Around 10 items)

  • 1 Dinner Plate
  • 1 Dessert Plate
  • Soup Bowl
  • Glass
  • Tea Cup & Saucer
  • Cutlery: Knife, fork, teaspoon, spoon

It includes a 6th sense cycle which uses sensors to automatically adjust the water and cycle dependant on the load. This clever technology helps to save energy and uses less water without compromising on cleaning power.
