Details

The Foreign Influence Registration Scheme (FIRS) will protect the safety and interests of the UK by improving the understanding of activity taking place in the UK at the instruction of a foreign state or certain foreign state‑controlled organisations. It is contained within part 4 of the National Security Act 2023.

This document provides additional sector-specific guidance on the Foreign Influence Registration Scheme for the defence and security sector, including:

  • defence companies that have close links to foreign power
  • the UK Crown bodies arrangement exemption in the context of defence
  • the circumstances in which exceptions to publication may apply for national security reasons

This guidance explains the main requirements of the FIRS scheme. However, if you are affected by FIRS, it is your responsibility to comply with the scheme based on your own specific circumstances.
