THFC has been issuing bonds with a social purpose since it was founded over thirty years ago. In recognition of the emerging ESG-related market conventions, THFC launched its group Social Bond Framework in May 2021 to allow the issuing of bonds with a 'Social' label. In November 2021 THFC published a Sustainable Bond Framework to allow the issuing of Sustainability Bonds in addition to Social Bonds. Vigeo Eiris provided the Second Party Opinion for both frameworks, rating THFC's contribution to sustainability with its highest 'Advanced' category. The reporting obligations set out in the framework are aligned with the social housing sector's Sustainability Reporting Standard, of which THFC is an early adopter.
