Thirteen reports 79.9% of homes at EPC C or above in 2025/26 ESG report

Housing association Thirteen has reported that 79.9% of its homes are now rated energy performance certificate (EPC) C or above, up from 75.13% a year earlier, in its environmental, social and governance (ESG) report for 2025/26.

The report, published on 2 October 2026, also said Thirteen created £66m of social value during the year and supported 9,625 people through its support services.

Thirteen said 98.4% of waste was diverted from landfill through its recycling centre.

The landlord has published a one-page summary of the year's figures alongside the full report. Thirteen describes the document as its sixth annual ESG report.

Energy performance

The prior-year EPC figure comes from Thirteen's own summary of its 2024/25 ESG report, which gave 75.13% of homes at EPC Band C or higher.

Report year	Homes rated EPC C or above
2024/25	75.13%
2025/26	79.9%

In that 2024/25 summary, Thirteen said it had insulated lofts in 771 homes and helped 865 people into employment or training. The 2025/26 announcement does not give equivalent figures for those two measures.

Thirteen has committed to reaching net zero direct business emissions by 2035, according to its environmental sustainability page.

The association says it was one of the first housing associations to adopt the Sustainability Reporting Standard, the sector's ESG reporting framework.

The organisation

Thirteen describes itself as a housing association supporting about 100,000 people across the North East, Yorkshire and Humber.

The Regulator of Social Housing said Thirteen owns 35,288 homes, predominately in the North East and Yorkshire, based on the 2025 statistical data return.

A regulatory judgement following a stability check completed in November 2025 confirmed a governance grade of G1 and a financial viability grade of V1. Thirteen also holds a consumer grade of C1 from a planned inspection completed in March 2025, the regulator said.

Thirteen's investor relations page reports first-quarter turnover of £59.2m, a year-on-year increase of £2.2m.

What happens next

Thirteen is building new homes through a five-year affordable homes programme that it says runs until 2029, six years before its 2035 target date for net zero direct business emissions.
