DY12 is below average for energy efficiency — most homes here have room to improve.
7.6% of homes are rated F or G — above the national average of 2.9%.
Data from 3,452 property assessments shows DY12 averaging 60 out of 100, placing it below the national average. For reference, the England and Wales average is 67 — so DY12 is below that benchmark. The most common rating band is D, with 6.9% of homes rated A or B and 66.1% in the C or D bands. Meanwhile, 7.6% of homes sit in the F or G bands — the least efficient categories. In practical terms, a rating of D means many homes here lose more heat than average — potentially adding £200-400 per year to energy bills compared to a C-rated home.
Walk through DY12 and you will mostly see houses. Around 73% of properties are owner-occupied . Gas central heating is the main fuel source for 77% of homes, which is typical for urban areas across England.
There is genuine room for improvement here. If every recommended upgrade were carried out, the average score could climb from 60 to 80 — a 20-point jump that would lift the typical rating to C. That is a substantial gain, suggesting many homes are missing basic efficiency measures.

Frequently asked questions
What is the average EPC rating in DY12?
Homes in DY12 have an average EPC rating of D, scoring 60 out of 100 for energy efficiency. That figure comes from 3,452 certificates issued across the district.
That is below the national average of 67, which means there is real scope to improve energy efficiency here. A D rating typically means higher-than-necessary heating bills, especially in older properties without adequate insulation.
What percentage of homes in DY12 are rated F or G?
7.6% of homes in DY12 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
That means DY12 has a higher-than-average proportion of poorly insulated homes. On the positive side, many of these properties may qualify for free improvements through government schemes like ECO4 or the Great British Insulation Scheme. Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
