Martyn’s Law is Now in Force: Why Reviewing Your Security Duties Should Be a Priority

Martyn’s Law creates a clear and proactive legal requirement to consider the threat of terrorism and take proportionate steps to reduce risk. Named in memory of Martyn Hett, who lost his life in the Manchester Arena attack in 2017, the legislation is grounded in the principle that better preparedness can save lives.

The Act introduces two distinct tiers of responsibility:

• Standard Tier – applying to premises with a capacity of 200–799 people. Those responsible will need to ensure they have basic, practical measures in place to prepare for and respond to a terrorist incident, including staff training and clear incident procedures.
• Enhanced Tier – applying to premises and events with a capacity of 800 or more. Here, the duties are more rigorous, including requirements for formal terrorism risk assessments and the implementation of detailed security planning measures.

These duties will apply across a wide range of sectors – including entertainment, retail, leisure, hospitality, healthcare, education, places of worship, and sports.

Why You Need to Review Now

Although the Act allows for a 24-month transition period before full enforcement begins, duty holders should not delay. The expectations placed on organisations – especially those in the Enhanced Tier – require time, planning, and, in many cases, a cultural shift in how risk is managed.

Early engagement will ensure your organisation:

• Understands which tier of duties applies to your premises or events;
• Has time to conduct suitable gap analyses;
• Can implement effective training, planning, and communication systems;
• Avoids rushed compliance, which increases the risk of ineffective arrangements or enforcement exposure.

What Happens if You Don’t Comply?

Failure to comply with Martyn’s Law will have consequences. The legislation provides enforcement powers to the Security Industry Authority, including inspections, compliance notices, and financial penalties. In the most serious cases, criminal proceedings could follow.

But beyond regulatory consequences, failure to act responsibly could have reputational, operational, and moral implications should an incident occur.

Final Thoughts

This new legal duty is about more than regulatory compliance – it’s about responsible leadership, risk ownership, and public trust. Organisations that proactively assess their exposure and strengthen their protective arrangements now will be better placed to meet legal obligations, reassure the public, and respond effectively should the unthinkable happen.

If you're unsure where to start, now is the time to seek expert advice. Preparation today is protection tomorrow.
