The Terrorism (Protection of Premises) Act 2025, widely referred to as “Martyn’s Law”, officially received Royal Assent on 3 April 2025, marking a significant step forward in the UK’s counter-terrorism framework. The legislation introduces new duties for those responsible for certain publicly accessible commercial premises to ensure they are both prepared for and protected from terrorist attacks.
Overview of the Act
The Act is named in memory of Martyn Hett, one of the 22 victims of the 2017 Manchester Arena attack, and is the result of a sustained campaign by his mother, Figen Murray OBE, who has campaigned for stronger security measures at venues and public spaces.
Under the new law, organisations responsible for qualifying premises—such as entertainment venues, large retail outlets, and public spaces with a capacity of 100 people or more—must now take appropriate and proportionate steps to mitigate the risk of terrorist attacks. The legislation introduces two tiers of duty:
- Standard Tier: Applies to premises with a capacity of 100 to 799 people, requiring them to undertake basic preparedness measures such as terrorism awareness training and the development of an emergency action plan.
- Enhanced Tier: Applies to venues with a capacity of 800 or more, requiring more rigorous measures, including a thorough terrorism risk assessment and detailed security planning.
The legislation is designed to ensure that security is considered as a fundamental part of managing publicly accessible spaces, much like health and safety responsibilities.
Commencement and implementation
Although the Terrorism (Protection of Premises) Act 2024 has now become law, not all of its provisions are yet in force. The Government has indicated that a phased implementation of at least 24 months will follow to allow businesses and organisations time to prepare. Commencement regulations are expected to be issued in due course, which will set out the precise dates when various parts of the Act will take effect.
The Home Office is also expected to publish further guidance and support materials for those with duties under the Act, particularly smaller organisations that may face challenges in understanding or implementing the new requirements.
Looking ahead
The Act represents a cultural shift in how the UK prepares for and responds to the threat of terrorism. It places legal duties on organisations to consider the risks and to put proportionate measures in place—steps which campaigners argue could make a critical difference in saving lives.
