Martyn’s Law - The Terrorism (Protection of Premises) Act 2025

The Terrorism (Protection of Premises) Act 2025, also known as Martyn’s Law, received Royal Assent on 3 April 2025 and marks a significant step in enhancing public safety. 

The act – named in memory of Martyn Hett, a victim of the Manchester Arena attack – requires events and public venues, including education settings, to assess and mitigate against terrorist attacks, and aims to protect the public by promoting preparedness, training, and clear action plans. 

There is a 24-month implementation period to allow settings to plan and prepare, with the Security Industry Authority overseeing compliance with the new legal requirements and who will also provide advice, guidance, and support to settings.
