The labels mark a return to the simpler A-G scale for energy efficiency replacing the A+, A++ and A+++ scale. The scale is stricter and designed so that very few products will initially able to achieve the "A" rating, leaving space for more efficient products to be included in the future.

At the end of February, over 90% of products were labeled either A+, A++ or A+++.

The new labels also have a QR code that allows consumers to access additional data on dimensions, features or test results.
