EPC bands in Monmouthshire, July 2025 to June 2026
| Rating | Certificates | Share |
|---|---|---|
| Band A | 82 | 4.3% |
| Band B | 195 | 10% |
| Band C | 868 | 45% |
| Band D | 517 | 27% |
| Band E | 186 | 9.7% |
| Band F | 52 | 2.7% |
| Band G | 8 | 0.4% |
40% below C (bands D to G) against 42% in Wales and 40% across England and Wales. Monmouthshire ranks 176 of 318 local authorities for the share below C (1 = highest share). Since 2008, 38,419 EPCs have been lodged for existing homes in Monmouthshire and 60% of them were below C — recent certificates run better than the long-run stock because newer and improved homes transact more.
The deeper problem here is the bottom of the scale. 13% of recent certificates in Monmouthshire were E, F or G — against 9.3% in Wales. F and G have been unlettable since the 2018–2020 minimum-E rules unless an exemption is registered, and an E-rated home has two bands to climb, not one; check the register before any new tenancy and budget for the cap being reached.
Is Monmouthshire moving towards C?
Little movement year on year in Monmouthshire: 39% of certificates were below C in July 2024 to June 2025 and 40% in July 2025 to June 2026 (+1.4 points; England and Wales −2.5 points). The area is 262nd of 318 for the size of its year-on-year change, so the picture here is stable rather than shifting.
The homes certified here are larger than typical — an average of 103.6 m² against 87.1 m² across England and Wales — and insulation, glazing and heating measures scale with floor area, so a D-to-C job here tends to sit at the upper end of any national cost guide.
What the 2030 rule costs in Monmouthshire
Privately rented homes need band C from 1 October 2030, with a £10,000 cap on what a landlord must spend before an exemption can be registered; the rules, exemptions and what counts towards the cap are on the EPC C for rentals by 2030 guide.
Put the £10,000 cap in local terms: average private rent in Monmouthshire is £993 a month (ONS, July 2026), so the cap is roughly 10.1 months of rent — and every month a property stands empty for works costs another £993 on top of the bill. The area’s rents, prices and yields are on Monmouthshire: rents, house prices and yield.
Whether the certificate and the works are deductible is on EPC, gas and electrical certificates: deductible? — revenue repairs come off the year’s rent, improvements that add capital value do not (allowable expenses guide).

Asked about EPCs here
Of EPCs lodged for existing homes from July 2025 to June 2026, 60% were band C or better and 40% were D to G; band D alone was 27%. (MHCLG live table EB1.)

From 1 October 2030 under the government's EPC consultation response, with a £10,000 spending cap before an exemption. Until then the minimum for a new letting is band E.
40% below C against 42% in Wales — a smaller share needing work.
No — only homes with an EPC lodged in the period (sold, let or built). Since 2008 the cumulative share below C is 60%, higher because older certificates and unimproved homes sit in that total.
