Membership of the Certass certification scheme is not automatic.
Member companies are assessed inline with the standards laid down in EN17065 and specific license requirements of MHCLG, TrustMark, PAS2030 or Certass.This means that Certass financially and technically assesses its members to ensure they meet required standards.
In addition to initially assessing every member each year, Certass will inspect a sample of work submitted by the member for scheme compliance. Where appropriate, Certass notifies the local authority and issues a Building Regulation Compliance Certificate to the homeowner.
