FENSA LogoFENSA 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.

For peace of mind, homeowners can use a FENSA registered business for your double glazing installations:

1. Keep your FENSA certificate safe – you can’t sell your home without it.

2. Avoid rogue traders – use a FENSA installer

3. 92% of windows and doors are covered by FENSA in the UK .

4. More than 10 years of raising standards in the glazing industry.

5. FENSA is the original Competent Persons Scheme.

6. FENSA – the quick and simple route to building regulations compliance
