Martyn's Law Explained

Understanding the Terrorism (Protection of Premises) Act 2025 and what it means for public safety, security preparedness, emergency planning and life safety systems.

Security Systems

Preparing for Martyn's Law?

The introduction of Martyn's Law, formally known as the Terrorism (Protection of Premises) Act 2025, represents one of the most significant changes to public safety legislation in recent years.

The law is designed to improve protective security and organisational preparedness across publicly accessible locations throughout the UK. For many premises, this means looking closely at emergency planning, communication, evacuation, lockdown, access control, CCTV and wider life safety systems.

What Is Martyn's Law?

Martyn's Law was introduced following the Manchester Arena terrorist attack in 2017 and the campaign led by Figen Murray, mother of Martyn Hett.

The legislation received Royal Assent on 3 April 2025 and is intended to strengthen protective security across qualifying premises and events.

Key Takeaway: The Government has confirmed an implementation period before enforcement begins, giving organisations time to understand responsibilities and prepare for compliance.

Invacuation

Bringing people inside a building from outdoor areas to protect them from an external threat.

Evacuation

Moving people away from danger using the safest available routes.

Communication

Ensuring staff and the public are informed clearly and quickly during an incident.

Fire Detection Still Plays a Critical Role

While Martyn's Law is centred on terrorist threats rather than fire incidents, both rely on fast detection, clear communication and an organised response.

Early Warning

Intelligent fire detection helps alert occupants and emergency teams quickly, supporting safer evacuation and response procedures.

System Integration

Fire systems can often work alongside voice alarm, access control, smoke control and building management systems.

Occupant Safety

Accurate detection and notification help facilities teams maintain clear emergency procedures and protect building users.

The Growing Importance of Security Technology

CCTV Systems

CCTV can support real-time situational awareness, incident monitoring, perimeter observation and evidence capture.

Access Control

Access control can help manage restricted areas, visitor access, staff safety and emergency lockdown procedures.

Voice Communication

Voice alarm and emergency communication systems can help deliver clear instructions when people need them most.

Intruder Detection

Intruder detection can provide early warning of unauthorised access and support a wider security management strategy.
