How the North East compares
Across all its homes the North East is 4th of England's 9 regions for the share rated C or above, slightly ahead of England as a whole. Its privately rented houses tell a different story: detached, semi-detached and terraced all have a typical score in band D. Rented terraced houses are at 65, 4 points short of C, and below England's 66.

What would get them to C
We read 600 certificates of Stockton-on-Tees homes rated D to G in full. Doing everything on its certificate would take 91% of them to C or better, though most lists end with solar panels. These are the improvements suggested most often, with the register's typical costs.
- Low-energy lightingTypically £1558%
- New condensing boilerTypically £2,200 – £3,00040%
- Heating controls (thermostat and radiator valves)Typically £350 – £45038%
- Floor insulation (suspended floor)Typically £800 – £1,20032%
- Floor insulation (solid floor)Typically £4,000 – £6,00028%
- Cavity wall insulationTypically £500 – £1,50021%
Percentages are the share of those certificates suggesting it. Costs are typical ranges printed on the certificates, not quotes.
What the government plans
Private rentals in England and Wales must be rated E or better today. In its January 2026 response the government confirmed plans to raise that to C for every tenancy by 1 October 2030. Landlords would spend up to £10,000 per property (less on homes worth under £100,000) before they could register an exemption, and face fines of up to £30,000. The plans still need legislation, expected in 2027.
The register covers homes sold or let since 2008, owner-occupied as well as rented, so these figures describe Stockton-on-Tees's housing with an EPC, not rentals alone.
How we did it
- We looked up every postcode in TS15–TS23 on the government's EPC register on 7 November 2026, using the postcode lists in OS Code-Point Open.
- Each home counts once, by its latest certificate. A certificate expires ten years after it was lodged.
- Districts are grouped into towns as our town pages are (whole postcode districts by post town), not by council boundaries.
- Improvements come from a random sample of 200 D–G certificates per town, read in full. Solar panels, solar water heating and wind are left out of the list because nearly every certificate ends with one.
- Ratings describe each home when it was assessed: improvements made since only show on a new EPC.
