Washing Machine Energy Ratings
If you’re thinking about upgrading your washing machine to a newer model, it’s worth getting clued up on energy efficiency ratings. Appliances with a good energy rating save you money on electricity and water bills, as well as helping you look after the environment.
EU energy efficiency ratings can be a little confusing at first, but we’ve put together this guide to answer all your questions.
Why Do We Need Energy Labels?
All appliances these days have an EU energy efficiency label.
This means you can easily compare different models to check running costs and get an idea how green they are. It also forces manufacturers to take more responsibility for the environment.
Energy efficiency ratings are shown on the label and take the form of a letter – much like the grade you’d get on a test.
Washing Machine Energy Labels Explained
Since 2014, washing machines can only be rated A+++ (most energy efficient), A++, A+ or A (least energy efficient). However, you may still find older models for sale with B to D ratings.
You’ll also find other information on washing machine energy labels, including annual water consumption (in litres), capacity (in kilograms), spin drying efficiency (rated from A to G) and noise emission (in decibels). This is really useful if you’re struggling to choose between two models.
The most energy efficient washing machines are endorsed by the Energy Saving Trust. The easiest way to find these models is to look for the Energy Saving Recommended logo.
How Are Energy Ratings Calculated?
Washing machine ratings are based on the kilowatt hours used annually for full and partial 60°C cotton loads and a 40°C partial cotton load.
It’s worth keeping in mind that the label may not provide a true reflection of the energy efficiency of the machine if you use different cycles to those used for the test.
What about Water Consumption?
The EU energy rating doesn’t take water usage into account, only electricity. The water consumption is shown elsewhere on the label but doesn’t contribute to the overall rating.
The average washing machine uses up to 11 litres of water for every kilogram of cottons washed using a standard 40°C programme. The 40°C synthetics program is less efficient however – using over 15 litres per kilogram to help avoid creasing.
