Our guide to Building Regulations for windows & door installations

Since April 2002, all glazing installations must comply with Building Regulations requirements. The regulations cover several aspects of replacement glazing criteria including safety, ventilation, means of escape and thermal performance. In general, most glazing installers will be able to provide the required documentation on completion of the installation. If a glazing installer is not registered with a competent person’s scheme, then the building owner will need to obtain approval from an approved inspector or local authority official.

Competent Person’s Scheme

Government approved competent persons scheme

There are several government approved competent persons schemes of which FENSA is the most well-known. FENSA (Fenestration Self-Assessment Scheme) was established by the Glass and Glazing Federation to ensure that all UK glazing installations comply with Building Regulations. To become a FENSA approved installer, a sample installation is checked by a FENSA approved inspector to ensure compliance.

Once an installation is completed, the approved installer will register the details with the approving body. The local authority will then be notified, and the building owner will receive a certificate showing that the work was completed in accordance with current Building Regulations.
