NAS Certification for
Cleaning Businesses.
Cleaning companies working for NHS trusts, housing associations, FM clients, and MOD facilities face strict compliance expectations. Modern Slavery Act, COSHH, GDPR, and Equality Act requirements mean cleaning business compliance is scrutinised before contract award. NAS provides the independently assessed proof you need.
Why Cleaning Businesses Need NAS Certification
Cleaning companies are under significant compliance scrutiny — particularly around Modern Slavery Act, GDPR, COSHH, and Employment Rights Act. NHS trusts, local authorities, and FM clients require cleaning contractors to demonstrate structured, independently assessed credentials before accessing their properties.
