NAS Certification for
Scaffolding Contractors.
Scaffolding and temporary access contractors operate in high-risk, work-at-height environments with significant compliance obligations. NAS provides independently assessed business compliance certification that gives main contractors, principal designers, and clients verifiable evidence of your business compliance standards — complementing trade schemes like NASC.
Why Scaffolding Contractors Need NAS Business Certification
Work at Height Regulations, CDM, LOLER, and PUWER are critical compliance frameworks for scaffolding businesses. Main contractors and principal contractors require independently verified evidence of business compliance before awarding scaffold contracts.
