NP7 is around the national average for energy efficiency.
7.1% of homes are rated F or G — above the national average of 2.9%.
When it comes to energy performance, NP7 in Monmouthshire manages an average of 64 out of 100, placing it around the national average. Compared to the national average of 67, that puts NP7 around the norm for England and Wales. The most common rating band is C, with 14.6% of homes rated A or B and 63.4% in the C or D bands. Meanwhile, 7.1% of homes sit in the F or G bands — the least efficient categories. In practical terms, a C rating suggests reasonably efficient homes, though there is still room for improvement on heating and insulation.
The area is characterised by houses. Around 65% of properties are owner-occupied and 19% are social housing. Gas central heating is the main fuel source for 75% 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 64 to 81 — a 17-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 NP7?
Homes in NP7 have an average EPC rating of D, scoring 64 out of 100 for energy efficiency. That figure comes from 8,801 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 NP7 are rated F or G?
7.1% of homes in NP7 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
That means NP7 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.
