What is FENSA?

FENSA stands for  the Fenestration Self-Assessment Scheme. Following Government encouragement, FENSA has been set up by the Glass and Glazing Federation (GGF) and other industry bodies in response to Building Regulations for double glazing companies in England and Wales.

When replacing windows and doors, homeowners must comply with current thermal performance standards and ensure they get a certificate from FENSA or Local Authority Building Control. FENSA enables companies that install replacement windows and doors to self-certify compliance under these Building Regulations without the need for a separate assessment from Building Control.

Why FENSA?

An independent report commissioned by the Government found FENSA to be the most successful of all competent person schemes to date in the UK, across all industries. FENSA is the leading brand trusted by consumers, all Local Authorities, industry and Government.
