United Kingdom Security Vetting (UKSV) launched on 1 January 2017 following the requirement in the 2015 Strategic Defence and Security Review (SDSR) to establish a single provider of government National Security Vetting Services. Bringing together the well respected vetting organisations: Defence Business Services National Security Vetting (DBS NSV), and Foreign and Commonwealth Services National Security Vetting (FCOS NSV), UKSV has a mandate to establish a single vetting database, portable vetting and standardised pricing across government. UKSV aims to operate as a highly efficient and customer focused organisation.

There are 3 security levels:

  • Counter Terrorist Check (CTC): is carried out if an individual is working in proximity to public figures, or requires unescorted access to certain military, civil, industrial or commercial establishments assessed to be at particular risk from terrorist attack
  • Security Check (SC): determines that a person’s character and personal circumstances are such that they can be trusted to work in a position which involves long-term, frequent and uncontrolled access to SECRET assets
  • Developed Vetting: (DV) in addition to SC, this detailed check is appropriate when an individual has long term, frequent and uncontrolled access to ‘Top Secret’ information. There is also Enhanced DV

Privacy and Data Protection

The General Data Protection Regulation (GDPR), applied to UK law by the Data Protection Act 2018, governs the way in which UKSV holds and processes your personal data. We have published a Privacy Notice that explains who we share it with, who the data controllers are and what rights you have. It tells you how you can go about raising a query or how, if you are not satisfied with the way in which we are processing your personal data, you can make a complaint. You can read this privacy notice at We also recommend that you read the Cabinet Office document HMG Personnel Security Controls, which explains the purpose for which we undertake national security vetting and the checks that are carried out.

Retention periods

We will retain your personal data for as long as we need to in order to safeguard national security. Normally this will be for a period of six years from the date on which your security clearance expires, lapses or is withdrawn. However, we may need to retain some personal data for longer than this in the interests of national security or to assist our defence in legal proceedings which have already started.
