The tracker did not include the A rating as the volume of A-rated properties in the UK is currently too low to give a reliable average. Ratings G through to B were looked at, and similar property types were directly compared.

When you contrast the highest-rated properties with the lowest ones, the disparity in energy costs is stark. For example, a G-rated 1-bed flat has an average annual energy bill of £6058, while a property upgraded to band B saw average energy costs of only £695. This is a considerable difference, saving the resident or owner of this property thousands of pounds a year.
Significant differences in annual energy costs were also observed rating-to-rating, suggesting substantial savings of hundreds of pounds can be made by upgrading just one EPC band. In some cases, these savings are in the thousands. Looking at 3-bed detached properties, the average annual energy bill is £10,052 for a G-rated property. However, this jumps down to £5539 per year for households rated F.
