New data shows that over half (55%) of homes in England and Wales hold an energy rating of ‘D’ or below.
This means that out of a total score of 100, homes have been rated as either:
D – Score of 55 to 68 (the home has average energy efficiency, but that there are still significant improvements that could be made to the property);
E – Score of 39 to 54 (a property has below-average energy efficiency, often found in homes that are poorly insulated and have outdated heating systems. Currently, this is the minimum energy efficiency threshold for rented properties);
F – Score of 21 to 38 (reflects a poorly performing home in terms of energy efficiency and is likely to have inefficient heating and little insulation) or
G – Score of 1 to 20 (thelowest rating and reflects a home with very poor energy efficiency. Homes that fall under this rating may have old single-glazing, very inefficient heating systems, and inadequate insulation.)
The data from local authorities, analysed by Emperor Paint ,has ranked the areas which have the highest proportion of homes with an energy rating of ‘D’ or below:
1. Isles of Scilly: Taking the top spot is the Isles of Scilly, where 84.97% of homes have an energy rating of ‘D’ or below. This equates to 1,102 homes out of a total of 1,297;
2. Gwynedd: Ranking in second is Gwynedd, where 74.32% of homes hold an energy rating of ‘D’ or below. This equates to 42,721 homes out of a total of 57,483;
3. Pendle: Closely following in third is Pendle at 74.05%, with 35,686 homes out of a total of 48,193 rated as ‘D’ or below for their energy performance.
EPC ratings are set to be overhauled, with four new metrics to measure energy performance: fabric performance, heating system, smart readiness, and energy cost, which will be introduced this year and become compulsory in October 2029.
Rental properties in England and Wales will be expected to have an equivalent minimum EPC rating of C (rising from E), which will apply to tenancies from October 2030. It could be harder to achieve this rating equivalent under the new system.
