EPC bands in Swindon, July 2025 to June 2026
| Rating | Certificates | Share |
|---|---|---|
| Band A | 33 | 0.7% |
| Band B | 209 | 4.4% |
| Band C | 2,910 | 62% |

33% below C (bands D to G) against 44% in the South West and 40% across England and Wales. Swindon ranks 271 of 318 local authorities for the share below C (1 = highest share). Since 2008, 91,039 EPCs have been lodged for existing homes in Swindon and 52% of them were below C — recent certificates run better than the long-run stock because newer and improved homes transact more.
Swindon splits fairly evenly. 67% of recent certificates are already C or better, 29% are one band short at D, and 3.7% are E, F or G. For a landlord that means the register is worth checking property by property: the same street can hold a certificate that needs nothing and one that needs two bands of work.
Is Swindon moving towards C?
Little movement year on year in Swindon: 35% of certificates were below C in July 2024 to June 2025 and 33% in July 2025 to June 2026 (−2.1 points; England and Wales −2.5 points). The area is 174th of 318 for the size of its year-on-year change, so the picture here is stable rather than shifting.
Average floor area per certificate is 83.5 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 Swindon
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 Swindon is £1,090 a month (ONS, July 2026), so the cap is roughly 9.2 months of rent — and every month a property stands empty for works costs another £1,090 on top of the bill. The area’s rents, prices and yields are on Swindon: rents, house prices and yield.
Council tax keeps running while a home is empty for works — Band D in Swindon is £2,438 for 2026/27, and the council adds a 100% premium once a home has stood empty for one year (council tax in Swindon). 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, 67% were band C or better and 33% were D to G; band D alone was 29%. (MHCLG live table EB1.)
The share below C moved from 35% (July 2024 to June 2025) to 33% (July 2025 to June 2026): −2.1 percentage points, against −2.5 across England and Wales.
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.
33% below C against 44% in the South West — 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 52%, higher because older certificates and unimproved homes sit in that total.
