EPC bands in Isles of Scilly, July 2025 to June 2026
| Rating | Certificates | Share |
|---|---|---|
| Band A | 0 | 0.0% |
| Band B | 0 | 0.0% |
| Band C | 2 | 2.6% |
| Band D | 16 | 21% |
| Band E | 23 | 30% |
| Band F | 26 | 34% |
| Band G | 9 | 12% |
97% below C (bands D to G) against 44% in the South West and 40% across England and Wales. Isles of Scilly ranks 1 of 318 local authorities for the share below C (1 = highest share). Since 2008, 1,238 EPCs have been lodged for existing homes in Isles of Scilly and 89% 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. 76% of recent certificates in Isles of Scilly were E, F or G — against 12% in the South West. 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 Isles of Scilly moving towards C?
The share below C in Isles of Scilly rose year on year, from 90% (July 2024 to June 2025) to 97% (July 2025 to June 2026) — up 7.1 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.
Average floor area per certificate is 82.9 m², close to the 87.1 m² England-and-Wales figure, so national cost guides apply here without much adjustment.
What the 2030 rule costs in Isles of Scilly
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.
Council tax keeps running while a home is empty for works — Band D in Isles of Scilly is £2,048 for 2026/27, and the council adds a 100% premium once a home has stood empty for one year (council tax in Isles of Scilly). 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).
