Our Accreditations



Standards are high at SEH Commercial. We are FENSA recognised – the industry standard for replacement windows and doors. We have ISO 9001:2008 standard for the Quality Management System for the manufacture of PVC-u windows, doors and conservatories as well as all the British Standard kite marks.

We are CHAS (Contractors Health and Safety Assessment Scheme) accredited and our Safe Contractor accreditation shows our dedication to higher standards of competence. Our Secured by Design accreditation focuses on crime prevention; our products offer the highest security features.

Safecontractor is the fastest growing health and safety accreditation scheme in the UK, with more than 200 major clients and over 18,000 contractor members.

At the heart of what we do is our national online database, the UK’s largest register for pre-qualified contractors and consultants.

Being the industry authority, the GGF promotes best practice and sets the highest technical and health & safety standards.

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.
