NAS Certification for
Fitters & Installers.
Kitchen fitters, window fitters, bathroom installers, and specialist installation contractors working for housing associations, house builders, and FM companies need business-level compliance credentials. NAS provides independently assessed certification covering the laws your clients check before awarding fitting and installation contracts.
Why Fitting & Installation Businesses Need NAS Certification
Whether you fit kitchens in social housing, windows in new-build developments, or specialist equipment in commercial properties — your clients require compliance credentials that go beyond trade qualifications. NAS covers the business compliance areas that procurement teams check at prequalification.
