D
CF83 Cardiff North
Caerphilly Rating D Score: 67 / 100

CF83 is around the national average for energy efficiency.

Data from 16,449 property assessments shows CF83 averaging 67 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so CF83 is around that benchmark. The most common rating band is D, with 10.3% of homes rated A or B and 77.7% in the C or D bands. Meanwhile, 1.7% 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 CF83 and you will mostly see houses. Around 62% of properties are owner-occupied and 24% are social housing. Gas central heating is the main fuel source for 96% 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 82 — a 15-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 CF83?

Homes in CF83 have an average EPC rating of D, scoring 67 out of 100 for energy efficiency. That figure comes from 16,449 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 CF83 are rated F or G?

1.7% of homes in CF83 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.

This is actually better than the national picture, suggesting the housing stock in CF83 is in relatively good shape — though any home rated F or G would still benefit enormously from basic upgrades. Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
