Martyn’s Law: What Organisations Need to Know to Prepare for the UK’s New Security Legislation

A large crowd at an outdoor concert faces a stage at sunset, with many people raising their hands and making rock hand gestures as the sun sets behind the stage structure.

Across the UK, organisations responsible for public spaces are preparing for one of the most significant changes to venue security in recent years: Martyn’s Law.

Formally known as the Terrorism (Protection of Premises) Act 2025, the legislation introduces a legal duty for organisations to consider the threat of terrorism and take practical steps to improve public safety.

While the law introduces new compliance requirements, its wider goal is clear: to ensure that venues, events and public spaces are better prepared to protect people in the event of a terrorist attack.

For many organisations, this will require a shift in how security planning, risk management and crisis response are approached.

Why Martyn’s Law Is Being Implemented

Martyn’s Law was introduced following the tragic Manchester Arena bombing in 2017, in which 22 people lost their lives.

Among them was Martyn Hett, whose mother Figen Murray launched a campaign calling for stronger protections at publicly accessible venues.

In the years following the attack, reviews highlighted that many organisations lacked consistent procedures for responding to terrorist threats. While counter‑terrorism policing in the UK is highly developed, preparedness at venue level varied significantly.

Martyn’s Law was therefore developed to ensure that organisations responsible for public spaces understand the risk of terrorism, implement proportionate security measures, and ensure staff know how to respond during an incident.

What the Law Requires

At its core, Martyn’s Law requires organisations to consider terrorism as part of their security planning and take appropriate steps to reduce risk.

The legislation introduces a duty for those responsible for certain premises or events to assess the risk of terrorist activity, implement measures to reduce vulnerabilities, prepare procedures for responding to incidents, and ensure staff are aware of how to react during an emergency.

Oversight and enforcement are expected to be managed by the Security Industry Authority (SIA).Which Organisations Will Be Affected?

Martyn’s Law applies to publicly accessible locations where people gather. Examples include shopping centres, restaurants, music venues, stadiums, museums, public buildings, places of worship and large public events.

In practice, any organisation responsible for a location where members of the public can freely access facilities may fall within scope.

Potential Penalties for Non‑Compliance

Potential Penalties for Non‑Compliance

While the primary goal of Martyn’s Law is preparedness rather than punishment, enforcement measures may include fines of up to £10,000 for Standard Tier organisations and up to £18 million or 5% of global turnover for Enhanced Tier organisations in serious cases.

For Standard Tier venues, compliance may involve staff awareness training, emergency planning procedures and evacuation planning.
Enhanced Tier organisations will likely require formal risk assessments, documented security plans and coordinated incident response procedures.

How Technology Can Support Martyn’s Law Compliance

For organisations operating in the Enhanced Tier, technology will play an important role in managing security preparedness and response.

Solutions such as those provided by F24 can help organisations rapidly communicate during incidents, coordinate crisis response teams, maintain documentation and audit trails, and run preparedness exercises to strengthen organisational resilience.

Preparing for the Future of Public Safety

Martyn’s Law represents a significant step forward in strengthening security across the UK’s public spaces.

For organisations responsible for venues and events, the legislation introduces new responsibilities but also an opportunity to improve resilience, preparedness and public safety.

By combining clear procedures, trained staff and the right technology, organisations can ensure they are ready to meet the expectations of the new law while protecting the people who rely on them.
