EPC bands in West Northamptonshire, July 2025 to June 2026
| Rating | Certificates | Share |
|---|---|---|
| Band A | 35 | 0.4% |
| Band B | 555 | 5.6% |
| Band C | 5,417 | 54% |

40% below C (bands D to G) against 46% in the East Midlands and 40% across England and Wales. West Northamptonshire ranks 178 of 318 local authorities for the share below C (1 = highest share). Since 2008, 50,565 EPCs have been lodged for existing homes in West Northamptonshire and 43% of them were below C — recent certificates run better than the long-run stock because newer and improved homes transact more. (West Northamptonshire was created by a council merger, so its cumulative figure only covers the new authority.)
West Northamptonshire splits fairly evenly. 60% of recent certificates are already C or better, 34% are one band short at D, and 6.4% 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 West Northamptonshire moving towards C?
The share below C in West Northamptonshire rose year on year, from 35% (July 2024 to June 2025) to 40% (July 2025 to June 2026) — up 4.6 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 87.6 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 West Northamptonshire
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 West Northamptonshire is £1,078 a month (ONS, July 2026), so the cap is roughly 9.3 months of rent — and every month a property stands empty for works costs another £1,078 on top of the bill. The area’s rents, prices and yields are on West Northamptonshire: rents, house prices and yield.
Council tax keeps running while a home is empty for works — Band D in West Northamptonshire is £2,487 for 2026/27, and the council adds a 100% premium once a home has stood empty for one year (council tax in West Northamptonshire). 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).
