About FENSA

FENSA is a government-authorised and UKAS-accredited competent person scheme monitoring building regulation compliance for the installation of replacement windows and doors in England and Wales.

FENSA’s mission is to improve window and door replacements across the UK, by professionalising installers while protecting homeowners. FENSA Approved Installers install over 500,000 jobs every year and over 14 million certificates have been issued since 2002.

When homeowners choose a FENSA Approved Installer, they receive a FENSA certificate when the work is complete: all the proof they need of a job done right. This certifies the work complies with building regulations, is energy efficient, registered with the local council and verifies that every FENSA Approved Installer’s guarantee is backed by insurance.
