The document discusses the TrustMark quality scheme and its evolution. TrustMark was formed in 2005 and aims to be the government-endorsed quality mark for home improvement trades. It operates by accrediting scheme providers who register businesses via a code of conduct and framework. There are emerging questions around TrustMark's relationship with other schemes, the requirements and liability of scheme providers, costs for contractors, and dispute resolution processes. The benefits of TrustMark include improved quality assurance, financial protection for consumers, and encouraging investment across sectors through a consistent quality approach.
