Fenestration Self-Assessment Scheme (FENSA)

Since 1 April 2002, all replacement glazing in dwellings comes within the scope of the Building Regulations. Anyone who installs replacement windows or doors must comply with improved thermal performance standards. When having their windows and doors replaced homeowners must either get a certificate from Local Authority Building Control or have the work completed by a FENSA Registered Company.

Glass and Glazing Federation

The Glass and Glazing Federation (GGF) represents companies who make, supply or fit, glass and glazing products in the UK and internationally.

Being the industry authority, the GGF promotes best practice and sets the highest technical and health & safety standards. The Federation is also the voice of the industry in local and national politics helping shape and influence policy and legislation. As well as offering an array of benefits to its members, the GGF guides and protects homeowners when buying glass or glazing products and services.
