Martyn’s Law Explained: What UK Venues Need to Do to Prepare

Everything venue operators, event organisers and facilities managers need to know about complying with the Terrorism (Protection of Premises) Act 2025.

Public safety has always been a priority for venue operators, but the introduction of Martyn’s Law, officially the Terrorism (Protection of Premises) Act 2025, makes security planning a legal responsibility for thousands of organisations across the UK.

Whether you operate a stadium, shopping centre, university campus, visitor attraction or organise temporary events, understanding your responsibilities now will help you prepare well before the legislation becomes fully enforceable.

This guide explains what Martyn’s Law is, who it applies to, and how the right physical security measures can help protect people while supporting compliance.

What is Martyn’s Law?

Martyn’s Law was introduced following the Manchester Arena terrorist attack in 2017 and is named in memory of Martyn Hett, one of the 22 victims.

The legislation establishes a consistent legal framework requiring those responsible for publicly accessible premises and qualifying events to consider the risk of terrorism and implement proportionate protective measures.

Rather than prescribing identical security for every venue, the Act takes a practical, risk-based approach based on the size and nature of each location.

Who Does Martyn’s Law Apply To?

The legislation covers a wide range of publicly accessible premises, including:

• Stadiums and sports venues
• Shopping centres and retail parks
• Music venues and theatres
• Universities and colleges
• Healthcare facilities
• Visitor attractions
• Conference centres
• Public buildings
• Temporary events and festivals
• Places of worship

If your premises regularly welcomes members of the public, it’s important to understand whether the legislation applies to you.

Standard Tier vs Enhanced Tier

Martyn’s Law introduces two levels of responsibility.

Standard Tier (200-799 people)

Smaller qualifying venues are expected to implement practical, low-cost procedures including:

• Staff awareness training
• Evacuation procedures
• Lockdown plans
• Communication processes
• Emergency response planning

Enhanced Tier (800+ people)

Larger venues and events must take additional steps, including:

• Comprehensive terrorism risk assessments
• Physical security measures
• Security management plans
• Appropriate monitoring
• Access control procedures
• Protective infrastructure where required

The emphasis throughout is on implementing measures that are proportionate to the level of risk.

Physical Security Matters

While staff training and emergency planning form an essential part of Martyn’s Law, physical security measures are equally important.

Depending on your venue and risk assessment, this could include:

Temporary Security Barriers

Create secure perimeters, protect entrances and manage pedestrian movement during busy periods or temporary events.

Hostile Vehicle Mitigation (HVM)

Prevent unauthorised vehicle access into crowded public spaces using tested hostile vehicle mitigation systems.

Crowd Management Barriers

Guide visitors safely through entrances, exits and queueing areas while maintaining orderly pedestrian flow.

Temporary Fencing

Protect restricted areas, back-of-house operations and service zones from unauthorised access.

Access Control

Clearly define public and restricted areas to improve security and emergency management.

These measures don’t just help reduce risk—they also demonstrate a proactive approach to public safety.

Preparing for Compliance

If your organisation hasn’t started preparing, now is the ideal time.

A practical approach includes:

1. Understand Your Responsibilities

Determine whether your premises or event falls within the scope of the legislation.

2. Carry Out a Risk Assessment

Identify potential vulnerabilities, access points and areas where large crowds gather.

3. Review Existing Security

Assess your current procedures, equipment and physical security measures.

4. Identify Improvements

Look for practical ways to strengthen site security using proportionate solutions.

5. Train Your Staff

Ensure everyone understands their role during an emergency.

6. Review Regularly

Security threats evolve, and your plans should too.

Frequently Asked Questions

Is Martyn’s Law already in force?

Yes. The Terrorism (Protection of Premises) Act 2025 has received Royal Assent, with implementation being phased in alongside government guidance before full enforcement.

Does every venue need security barriers?

Not necessarily. The legislation requires measures that are proportionate to the risks identified during your assessment. Some venues may require temporary barriers or hostile vehicle mitigation, while others may only need procedural improvements.

What is Hostile Vehicle Mitigation?

Hostile Vehicle Mitigation (HVM) uses specially designed barriers and security systems to prevent unauthorised vehicles entering areas occupied by pedestrians.

Can temporary events comply?

Yes. Festivals, outdoor events and temporary venues are included where they meet the qualifying criteria. Temporary barriers, fencing and HVM systems are commonly used to help secure these environments.
