EPC bands in Isle of Anglesey, July 2025 to June 2026
| Rating | Certificates | Share |
|---|---|---|
| Band A | 43 | 2.3% |
| Band B | 263 | 14% |
| Band C | 562 | 30% |
| Band D | 528 | 28% |
| Band E | 312 | 17% |
| Band F | 115 | 6.2% |
| Band G | 36 | 1.9% |
53% below C (bands D to G) against 42% in Wales and 40% across England and Wales. Isle of Anglesey ranks 29 of 318 local authorities for the share below C (1 = highest share). Since 2008, 38,221 EPCs have been lodged for existing homes in Isle of Anglesey and 73% 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. 25% of recent certificates in Isle of Anglesey 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 Isle of Anglesey moving towards C?
The share below C in Isle of Anglesey rose year on year, from 50% (July 2024 to June 2025) to 53% (July 2025 to June 2026) — up 3.3 points against −2.5 points across England and Wales. A rise usually says more about which homes happened to sell or let — older, unimproved stock coming to market — than about homes getting worse; what it does mean is that more of what is on the market here needs work before it can be let after 2030.
The homes certified here are larger than typical — an average of 96.3 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 Isle of Anglesey
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 Isle of Anglesey is £710 a month (ONS, July 2026), so the cap is roughly 14.1 months of rent — and every month a property stands empty for works costs another £710 on top of the bill. The area’s rents, prices and yields are on Isle of Anglesey: 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).
