NAS Certification for
Plant Operators & Plant Hire Contractors.
Plant operators, plant hire companies, and earthmoving contractors work on some of the highest-risk construction and infrastructure sites in the UK. NAS provides independently assessed business compliance certification that complements CPCS and NPORS operator cards — giving main contractors, infrastructure clients, and principal designers verifiable evidence of your business compliance standards.
Why Plant Operators & Plant Hire Contractors Need NAS Certification
CPCS and NPORS cards prove operator competence. NAS certifies business compliance. Main contractors, infrastructure clients, and principal contractors require independently verified business compliance evidence before mobilising plant hire businesses on site.
