Energy Efficiency Bands

SEDBUK efficiencies are expressed as a percentage, and an A to G scale of percentage bands was also in use until October 2010. This has been withdrawn to avoid confusion with the proposed European energy label using similar ratings based on different principles. The meaning of the SEDBUK bands was as follows:

Band SEDBUK range
90% and above
86% - 90%
82% - 86%
78% - 82%
74% - 78%
70% - 74%
below 70%
