Energy Efficiency Ratings for Washing Machines

Energy Efficiency Ratings for Washing Machines

Your washing machine power is measured in kilowatts per hour (kWh). When calculating energy efficiency, the kWh and energy consumption are measured over 100 cycles using a 40-60°C eco wash. An eco wash is the most efficient setting and washes everyday materials and stains – making it the most accurate way to test energy efficiency.

On top of choosing a washer with a high rating, here are more ways to make the appliance more efficient:

  • Don’t overload the machine drum
  • Select the most efficient setting (which might be a shorter cycle)
  • Stay on top of your washing machine maintenance

Why has the energy label changed?

With 'A' being associated with a good rating by consumers, the addition of A+, A++ and A+++ ratings made the old system less transparent as products moved up the scale due to improvement in product efficiency. The revised A-G system has reset the scale, making it easier to understand, as well as incentivising manufacturers to product even more efficient products.

What has changed on the new label?

The scale is now between A-G, with no extensions to A+ classes anymore. The label will also feature the Union flag as opposed to the EU version post-Brexit. Some new icons have been added, and older ones adapted, to provide a more transparent insight into the products.

Which product categories are changing?

Lighting, Fridges/Freezers, Washing Machines, Washer-Dryers, Dishwashers and Wine Storage are now on the new rating system. Changes to further product categories will occur in 2026, this will include Tumble Dryers, Range Cookers and Hoods.

What do we mean by energy efficient?

If an appliance is deemed energy efficient, it operates effectively using less energy. An energy-efficient appliance saves you money and helps you live sustainably. The formula to calculate energy efficiency considers how much power an appliance uses and produces. This means we look for the product that uses the least energy to provide the right amount of power.

How do energy ratings affect your appliances?

As your appliances are fit for different purposes, their energy efficiency is assessed differently.
