Require NAS-Certified Contractors
On Your Defence Estate Projects.
Ministry of Defence estate managers, DIO, and defence procurement teams operate within one of the most stringent compliance frameworks in the public sector. Contractors on defence sites must be held to a higher standard. NRTAUK NAS provides independently assessed, publicly verifiable contractor compliance — covering Bribery Act, Modern Slavery, Public Contracts Regulations, and more.
Why Require NAS From Your Defence Contractors?
Defence procurement carries obligations that go beyond standard commercial supply chain management. Bribery Act, Money Laundering, Freedom of Information, and Public Contracts Regulations all impose specific duties on MOD and DIO as contracting authorities. Contractor compliance must be independently verified, not assumed.
