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

EPC bands in Brentwood, July 2025 to June 2026

42% below C (bands D to G) against 41% in the East of England and 40% across England and Wales. Brentwood ranks 151 of 318 local authorities for the share below C (1 = highest share). Since 2008, 32,253 EPCs have been lodged for existing homes in Brentwood and 62% of them were below C — recent certificates run better than the long-run stock because newer and improved homes transact more.

Brentwood splits fairly evenly. 58% of recent certificates are already C or better, 36% are one band short at D, and 5.5% 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 Brentwood moving towards C?

Little movement year on year in Brentwood: 43% of certificates were below C in July 2024 to June 2025 and 42% in July 2025 to June 2026 (−0.9 points; England and Wales −2.5 points). The area is 221st 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 100 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 Brentwood

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 Brentwood is £1,618 a month (ONS, July 2026), so the cap is roughly 6.2 months of rent — and every month a property stands empty for works costs another £1,618 on top of the bill. The area’s rents, prices and yields are on Brentwood: rents, house prices and yield.

Council tax keeps running while a home is empty for works — Band D in Brentwood is £2,258 for 2026/27, and the council adds a 100% premium once a home has stood empty for two years (council tax in Brentwood). 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).
