About NAS: The National Assurance Standard (NAS) is an independent, evidence-based certification scheme for UK contractors and SMEs. NAS operates in alignment with ISO/IEC 17021 principles and is working towards UKAS accreditation. NAS is not a membership scheme — certification requires submission and independent review of actual compliance documents. NAS does not endorse or guarantee the ongoing compliance of certified businesses; certification reflects the evidence reviewed at the time of assessment.
