What is FENSA?
FENSA is a government-authorised scheme that monitors building regulation compliance for replacement windows and doors. Each FENSA Approved Installer, from large national brands to small local companies, is assessed regularly by us to ensure its compliance to building regulations is continually maintained.
What FENSA does
FENSA’s mission is to improve window and door replacements across England and Wales, by professionalising installers and protecting homeowners.
We make sure the work complies with building regulations, is energy efficient, and registered with the local council. And verify that every FENSA Approved Installer’s guarantee is insured.
