Study Reveals Energy Efficiency Ratings Of UK Homes

  • 4.5 times as many domestic buildings receiving A ratings in the last ten years, however they still only account for 0.6% of all home ratings

  • 48% decrease in the amount of G rated domestic homes in the last decade

  • South of England has the highest number of A rated domestic buildings

  • Renewable heat experts offer advice on improving energy efficiency through home heating solutions

Renewable heat experts Abode Heat, highlight the improvement of energy efficiency in domestic buildings, as it reveals the latest figures on ratings. 

Abode Heat has analysed more than ten years of historical government data from the Energy Performance of Buildings Certificates (EPC) register, and it can today reveal the huge progress in UK homes receiving A ratings, and identify which areas of the UK have the most energy-efficient domestic buildings. 

The study revealed that there has been a significant improvement in the overall scores of the 16.6 million EPCs recorded in the last decade. In 2013, there were 2,297 domestic buildings, or homes, in England and Wales achieving the highest A rating for their energy performance. Fast forward a decade later, and there were 10,353 in 2022 with a highest A rating; a significant 350% decrease and a huge milestone for the property industry with its improved approach to energy efficiency and the environment.

Ben Hodges, Director at Abode Heat comments: “It’s great to see this energy efficiency improvement on a domestic scale. 2022 itself was a record year for homes receiving an A rating on the EPC register, with a 74.7% increase from 2021 to 2022 figures. Whilst this is great for the environment, the UK’s net zero targets, and the buildings’ performance, it is worth noting that there is still a way to go as most buildings are receiving a C rating, with 39.4% of the 1.76 million rated domestic properties in 2022 scoring C. 

“The EPC register tracks ratings of buildings, but these are only required when sold, rented or built, so it’s unlikely to be a truly accurate representation of the UK domestic building stock as a whole right now for energy efficiency. What it does indicate though is a steady increase year-on year on homes receiving higher ratings, which is extremely positive for the building industry. There has been a notable 48% decrease in the amount of G-rated domestic homes in the last decade (since 2013), to highlight this too.”

Energy Performance Certificates are important for UK homes to measure efficiency and ensure they are meeting current standards and regulations. For domestic buildings in the study, here is how they fare with the latest data from the last 12 months:

Rating

No. of buildings with the rating

% of overall domestic buildings

A

10,353

0.6%

B

270,959

15.4%

C

694,775

39.4%

D

585,956

33.3%

E

157,789

8.9%

F

30,960

1.8%

G

10,464

0.6%

“There are many measures homeowners, developers and builders can take to improve energy efficiency ratings. Committing to upgrades or installation of best possible products like double-glazing, and renewable energy sources like heat pumps or solar power are good practices. We’ve experienced an excess of 100% increase year-on-year in heat pump sales over the last four years, as more customers are seeking energy or heat solutions that are better for the environment. We only expect this to increase as gas boilers are no longer installed in new builds from 2025, and UK regulations and government focus on carbon reduction and net-zero goals become a greater focus,” says Ben Hodges.

Where in England has the most energy efficient homes?

The EPC ratings also record a regional breakdown, and when analysing the data, Abode Heat looked into the total number of A-G ratings in homes since 2008. Here is how each region in England fared and who had the highest number of A ratings from 2008-2022:

1. South West - 8733
2. South East - 7952
3. East of England - 7380
4. London - 4814
5. Yorkshire and the Humber - 4804
6. West Midlands - 4491
7. East Midlands - 4139
8. North West - 3726
9. North East - 2094 

Ben Hodges says: “As a heat pump specialist in the South West, we are delighted to see our region receive the most A ratings in the EPC register. The south of England has an abundance of new builds and homes sold in the last few years as the pandemic and coastal factors make it a more idyllic settlement choice, so this could be contributing to the higher number of new builds or homes with high energy efficiency ratings. It also will be in part due to the number of providers in other areas that make choices such as solar PV panels, or a heat pump, a practical solution for homeowners and developers. With the South West currently having more than 4 times as many A rated domestic buildings than the North East since 2008, we hope this will level out over the coming years as adoption of energy-efficient measures around the whole UK increases.”
