Welcome to the DVA website.

We are the UK's largest government organisation carrying out National Security Vetting (NSV), and the only government organisation whose core business is NSV.

Within the defence community we provide NSV through direct financing to the three Armed Services, MOD civil service, and defence contractors.

We also deliver a range of NSV services on a repayment basis to a growing community of customers across the public sector. We have more repayment customers than any other UK NSV organisation.

Our customers are provided with assurances ranging from site admission to unrestricted access to material classified up to Top Secret. This assurance can be tailored to individual risk management needs. We also provide a service of help and customer engagement through visits and group open days to support this work.
