34% below C (bands D to G) against 41% in the East of England and 40% across England and Wales. Cambridge ranks 259 of 318 local authorities for the share below C (1 = highest share). Since 2008, 56,003 EPCs have been lodged for existing homes in Cambridge and 54% of them were below C — recent certificates run better than the long-run stock because newer and improved homes transact more.
Cambridge splits fairly evenly. 66% of recent certificates are already C or better, 30% are one band short at D, and 4.0% 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 Cambridge moving towards C?
Little movement year on year in Cambridge: 36% of certificates were below C in July 2024 to June 2025 and 34% in July 2025 to June 2026 (−2.1 points; England and Wales −2.5 points). The area is 173rd 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 84.5 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 Cambridge
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 Cambridge is £1,806 a month (ONS, July 2026), so the cap is roughly 5.5 months of rent — and every month a property stands empty for works costs another £1,806 on top of the bill. The area’s rents, prices and yields are on Cambridge: rents, house prices and yield.
Council tax keeps running while a home is empty for works — Band D in Cambridge is £2,467 for 2026/27, and the council adds a 100% premium once a home has stood empty for one year (council tax in Cambridge). 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, 66% were band C or better and 34% were D to G; band D alone was 30%. (MHCLG live table EB1.)
The share below C moved from 36% (July 2024 to June 2025) to 34% (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.
34% below C against 41% in the East of England — 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 54%, higher because older certificates and unimproved homes sit in that total.
