Your HETAS Registered Installer will provide you with a HETAS Certificate of Compliance (Building Regulation Compliance Certificate) on the completion of installation work. The certificate demonstrates that the installation complies with the relevant Building Regulations. The information on the certificate is used to record your installation and, in England & Wales, it is used to notify your Local Authority Building Control Department (LABC) of the work that was undertaken. This self certification takes the place of a Local Authority Building Notice. The information can be required to validate your home insurance and will be required in any home selling process. Failure to notify the Local Authority can be an offence resulting in enforcement action.
