CF61 Vale of Glamorgan
Vale of Glamorgan Rating D Score: 67 / 100

CF61 is around the national average for energy efficiency.

3.3% of homes are rated F or G — above the national average of 2.9%.

Data from 2,931 property assessments shows CF61 averaging 67 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so CF61 is around that benchmark. The most common rating band is D, with 15.4% of homes rated A or B and 71.0% in the C or D bands. Meanwhile, 3.3% 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 CF61 and you will mostly see houses. Around 69% of properties are owner-occupied . Gas central heating is the main fuel source for 91% 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 67 to 83 — a 16-point jump that would lift the typical rating to B. That is a substantial gain, suggesting many homes are missing basic efficiency measures.

Frequently asked questions

What is the average EPC rating in CF61?

Homes in CF61 have an average EPC rating of D, scoring 67 out of 100 for energy efficiency. That figure comes from 2,931 certificates issued across the district.

This is broadly in line with the national average of 67 — neither particularly efficient nor particularly wasteful. A D rating typically means higher-than-necessary heating bills, especially in older properties without adequate insulation.

What percentage of homes in CF61 are rated F or G?

3.3% of homes in CF61 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.

That means CF61 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.
