Previously, appliances had energy labels from A+++ which are highly efficient appliances,
down to G, which is a less efficient appliance.
Over the past 5 - 10 years, new innovations in technology have led to products being much
more efficient, and this has led to ratings at the A+++ level being overpopulated. The
energy label scale has been reset to clearly show the difference in efficiency between
products sold today, to make it easier to decide which product is best for you.
