EPC bands in Harrow, July 2025 to June 2026
| Rating | Certificates | Share |
|---|---|---|
| Band A | 24 | 0.3% |

38% below C (bands D to G) against 34% in London and 40% across England and Wales. Harrow ranks 220 of 318 local authorities for the share below C (1 = highest share). Since 2008, 91,820 EPCs have been lodged for existing homes in Harrow and 63% of them were below C — recent certificates run better than the long-run stock because newer and improved homes transact more.
Harrow splits fairly evenly. 62% of recent certificates are already C or better, 34% 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 Harrow moving towards C?
The direction of travel in Harrow is good. Between July 2024 to June 2025 and July 2025 to June 2026 the share of certificates below C fell from 44% to 38% — a drop of 6.1 percentage points, the 68th 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 79.7 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 Harrow
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 Harrow is £1,773 a month (ONS, July 2026), so the cap is roughly 5.6 months of rent — and every month a property stands empty for works costs another £1,773 on top of the bill. The area’s rents, prices and yields are on Harrow: rents, house prices and yield.
Council tax keeps running while a home is empty for works — Band D in Harrow is £2,511 for 2026/27, and the council adds a 100% premium once a home has stood empty for one year (council tax in Harrow). 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, 62% were band C or better and 38% were D to G; band D alone was 34%. (MHCLG live table EB1.)

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.
38% below C against 34% in London — a larger 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 63%, higher because older certificates and unimproved homes sit in that total.
