Foreign Direct Investment Regulations.
Foreign Direct Investment (FDI) Regulations
1. Introduction
Foreign Direct Investment (FDI) refers to investment made by a foreign entity into a UK company or asset with the intent to establish a lasting interest, typically through ownership, control, or significant influence. FDI is a vital driver of the UK economy, but it is subject to regulatory oversight to protect national security, strategic industries, and public interest.
Key legal frameworks include:
National Security and Investment Act 2021 – primary legislation for reviewing FDI in strategic sectors
Companies Act 2006 – corporate governance and reporting obligations
Competition Act 1998 – addresses anti-competitive risks from foreign ownership

7. Key Takeaways
FDI in the UK is heavily regulated to protect national security and public interest.
The National Security and Investment Act 2021 empowers the government to review, condition, or block transactions.
Failure to comply with FDI regulations may lead to civil penalties, criminal liability, or forced divestment.
Directors and corporate officers must exercise due diligence and ensure regulatory compliance.
Case law confirms that UK courts support government discretion but allow for judicial review where statutory powers are misapplied.
Effective FDI compliance requires pre-transaction risk assessment, notification, and ongoing governance oversight.
