EPC Ratings in Somerset: How Many Homes Are Below Band C Before the 2030 Rule

EPC bands in Somerset, July 2025 to June 2026

43% below C (bands D to G) against 44% in the South West and 40% across England and Wales. Somerset ranks 136 of 318 local authorities for the share below C (1 = highest share). Since 2008, 43,685 EPCs have been lodged for existing homes in Somerset and 47% of them were below C — recent certificates run better than the long-run stock because newer and improved homes transact more. (Somerset was created by a council merger, so its cumulative figure only covers the new authority.)

Somerset splits fairly evenly. 57% of recent certificates are already C or better, 30% are one band short at D, and 13% 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 Somerset moving towards C?

The direction of travel in Somerset is good. Between July 2024 to June 2025 and July 2025 to June 2026 the share of certificates below C fell from 46% to 43% — a drop of 3.6 percentage points, the 131st largest fall among the 318 areas with a year-on-year figure (England and Wales overall: −2.5 points).

Average floor area per certificate is 93.9 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 Somerset

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 Somerset is £1,006 a month (ONS, July 2026), so the cap is roughly 9.9 months of rent — and every month a property stands empty for works costs another £1,006 on top of the bill. The area’s rents, prices and yields are on Somerset: rents, house prices and yield.

Council tax keeps running while a home is empty for works — Band D in Somerset is £2,561 for 2026/27, and the council adds a 100% premium once a home has stood empty for one year (council tax in Somerset). 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).
