FENSA is a government-authorised scheme that monitors building regulation compliance for replacement windows and doors. FENSA Approved Installers are assessed regularly by an independent inspections body. 

Homeowners receive a FENSA Building Regulations Certificate, 5-10 year insurance-backed guarantees, written contracts and deposit protection. FENSA is non-profit making.

The scheme covers...

• Replacement external windows, doors, roof windows and roof lights in domestic dwellings. Note that the property must be sited on its original footprint, and the use and size of rooms must not be altered.

FENSA does not cover the installation of windows and doors in new conservatories, porches, new builds, new extensions, repairs (where frame not included) and commercial properties.
