Martyn’s Law – the Terrorism (Protection of Premises) Act 2025 – improves protective security and organisational preparedness across the UK by requiring, for the first time, that those responsible for certain premises and events consider terrorist risk and how they would respond to an attack.
Through the act, qualifying premises and events must should be better prepared and protected, ready to respond in the event of a terrorist attack.
The animation is simplified to aid a typical event or venue work out if they qualify. Exemptions may apply.
The act has been designed to bolster the UK’s preparedness for, and protection from, terrorism. Those responsible for certain premises or events will be required to implement reasonably practicable public protection procedures and/or measures, depending on the capacity of the premise. Premises that are reasonably expected to have 200-799 individuals on the premises at the same time will fall within the standard tier and where it is reasonably expected to have 800 individuals or more will fall in the enhanced tier.
Events that are reasonably expected to have 800 or more individuals in attendance at the same time, at some point during the duration of the event, will also be captured under the act and subject to the same enhanced tier requirements. The requirements of the act will ensure qualifying premises and events are better prepared to respond to, and mitigate the impact of, a terrorist attack.
The Decision Support Centre and the National Events Database
Through the National Events Database we intend to create a comprehensive database of premises and events detailing, who, what, where and when. Database members may benefit from greater awareness of event landscapes and preparedness considerations.
