Martyn’s Law: Enhancing Public Safety Across the UK

While such attacks are rare, the threat of terrorism remains real and increasingly unpredictable. Crowded public spaces are often seen as attractive targets, and attacks can happen anywhere, making prevention complex and urgent.

Martyn's Law, officially the Terrorism (Protection of Premises) Act 2025, was enacted to strengthen security in public premises and events, particularly in light of the 2017 Manchester Arena bombing. This legislation, named in memory of victim Martyn Hett, places a legal duty on certain venues and event organizers to take steps to reduce the risk of harm from terrorist attacks. The law aims to improve security preparedness across the UK, with different requirements based on the size and type of venue.

In response to a number of recent low-sophistication terrorist attacks in public spaces, as well as large-scale incidents such as the Manchester Arena attack, the UK Government has developed new legislation to improve public protection.

Who Does Martyn’s Law Apply To?

Once fully enacted, Martyn’s Law will apply to those responsible for venues and public spaces used for:

  • Entertainment and leisure;

  • Retail and hospitality;

  • Museums, galleries, and visitor attractions;

  • Sports venues;

  • Government buildings (e.g., town halls);

  • Temporary events;

  • Places of Worship; and

  • Health and education settings.

Application to Schools

For schools and other education settings within the Standard Tier, the focus is on reasonable and practical measures that could mitigate harm in the event of an attack. There is no requirement for physical modifications to premises. Instead, schools should develop plans that are effective, tailored, and outcome-focused.

Key Obligations for Schools

  • Develop procedures for evacuation, invacuation, lockdown, and communication; and

  • Focus on:

    o Guide – directing people safely and efficiently.

    o Shelter – securing the site and providing refuge.

    o Communicate – relaying critical information to staff and students quickly.

Given that students and staff may be spread across multiple areas, schools must create systems that support rapid and authoritative communication during emergencies.

Recommended Security Measures for Schools

  • Clear evacuation and invacuation plans;

  • Monitoring of national/local threat levels;

  • Training for staff and students;

  • 24/7 security monitoring (if applicable);

  • Site perimeter controls and vehicle access management;

  • Comprehensive risk assessments;

  • Regular search and screening protocols;

  • Visible ID and access control policies;

  • Intruder alarm systems and CCTV surveillance;

  • Data protection and cyber security practices;

  • Presence of uniformed and plain-clothes police officers; and

  • Qualified and trained security personnel.

Key responsibilities:

  • Develop simple protective procedures, such as securing doors and guiding people to safe areas; and

  • Create and practice evacuation, invacuation, and lockdown plans.

Even for venues over 800 in capacity, childcare, primary, secondary, or further education settings will fall into the Standard Tier.

Enhanced Tier

For venues with a capacity of 800 or more people, or qualifying large events

Key responsibilities:

  • Carry out in-depth risk assessments, potentially with expert input;

  • Implement advanced security measures such as CCTV, physical barriers, or trained security personnel; and

Implementation Timeline and Enforcement

Martyn’s Law received Royal Assent on 3 April 2025. Organisations now have a 24-month window to fully comply with the legislation. An inspection and enforcement framework will support compliance and promote a positive security culture, with appropriate sanctions for non-compliance.
