Tenant Services Authority: Public Relations Mrs. Spelman To ask the Secretary of State for Communities and Local Government who in his Department authorised the Tenant Services Authority to enter into a contract with the public affairs company APCO. John Healey The Tenant Services Authority did not seek authorisation from this Department because it was not required to do so. Part 2, Chapter 2 of the Housing and Regeneration Act 2008 (2008 Act) establishes that there will be a corporate body known as the regulator for social housing. The regulator is the Tenant Services Authority (TSA); the 2008 Act establishes that it is not a servant of the Crown and can therefore determine its own procedures.
