FENSA is a government authorised scheme established in 2002 in response to the current Building Regulations. The scheme covers the quality of companies against building regulations that replace windows, doors, roof windows and roof lights in England and Wales. All windows and doors installed in properties since 1st April 2002 must have a FENSA certificate if work is completed by a FENSA member. FENSA members either register their work with local authority Building Control or join a Competent Person Scheme (CPS), the latter allows them to self-certify their work. Using a FENSA member gives you significant cost reductions as you avoid local authority inspections and fees. It also means you know that your FENSA member company has undergone rigorous tests and is regularly inspected to make sure that their work is compliant. All work undertaken by a FENSA member is issued with a certificate which you should keep safe in case it is needed in the future. White Cat Joinery is proud to be a member of FENSA.
