NAS Certification for
Carpenters & Joiners.
Whether you do first fix, second fix, shopfitting, or joinery fabrication — house builders, housing associations, and main contractors require carpentry subcontractors to demonstrate structured business compliance. NAS gives you the independently assessed certification to pass prequalification and win contracts.
Why Carpentry Businesses Need NAS Certification
Carpentry and joinery businesses on new-build sites and housing association maintenance contracts must demonstrate business-level compliance. CSCS cards confirm individual competency — NAS certifies your business against the UK laws and regulations your clients are checking.
