UNCLE looked at data across the 30 most populated cities in the UK to determine which homes have the best EPC ratings and which the worst.
The study found that more than 15 million homes have an EPC rating of D or below; the average EPC rating for UK homes is 68.
Just 0.4% of homes (99,000) have an EPC rating of A, with Milton Keynes ranking as the location where homes perform best, with 60% achieving C or above.
Blackpool ranks as the worst location for home energy performance, with 74% scoring D or below
The best areas for energy efficiency ratings
| Location | % of homes with EPC rating A-C |
| Milton Keynes | 60.3% |
| Peterborough | 55.6% |
| City of Westminster | 54.5% |
| Crawley | 54.4% |
| Cambridge | 54.1% |
| Swindon | 52.9% |
| Manchester | 52.0% |
| Slough | 50.5% |
| Warrington | 49.5% |
Ranking as the area with the highest percentage of high-energy efficient homes is Milton Keynes. Just over 60% of homes in the city have an EPC rating of C or above. This is likely down to the town having an influx of newly built homes over the past 10 years, with new developments continuing as plans for a further 3,500 homes have been proposed.
The worst areas for energy efficiency ratings
| Location | % of homes with EPC rating D-G |
| Blackpool | 74.1% |
| Southend-on-Sea | 69.7% |
| Bradford | 68.8% |
| Stoke-on-Trent | 64.1% |
