From 4 January 2022, the government will be able to scrutinise and intervene in certain acquisitions made by anyone, including businesses and investors, that could harm the UK’s national security. The government will be able to impose certain conditions on an acquisition. In rare instances, the government may unwind or block an acquisition completely.

The rules fall under the National Security and Investment Act.

This guidance tells you how to prepare for the new rules. It covers:

  • what types of acquisitions are covered by the new rules
  • whether you need to tell the government about an acquisition
  • how the government will scrutinise the acquisition
