Understanding Martyn’s Law: A New Era for Event Security in the UK

In 2025, the UK will see the implementation of Martyn’s Law, also known as the Terrorism (Protection of Premises) Bill. This significant piece of legislation is designed to ensure that public venues and spaces are better prepared against potential terrorist threats. It marks a historic shift in how venues and events across the country are expected to plan for and respond to emergencies, with a clear focus on protecting the public.
Named in memory of Martyn Hett, one of the 22 victims of the 2017 Manchester Arena bombing, Martyn’s Law is a direct response to the gaps in security that were exposed by the tragedy. The law is the result of tireless campaigning by Martyn’s mother, Figen Murray, who has worked to raise awareness about the need for stronger protective measures at public events.
So, what is Martyn’s Law all about, and what does it mean for event organisers, venue operators, and security staff?

Why Martyn’s Law Was Introduced
The Manchester Arena bombing on May 22, 2017, was a turning point in the UK’s approach to event security. The attack targeted a pop concert attended mostly by young people and families. The bomber was able to enter a public space within the venue, loiter undetected, and then detonate an explosive device, resulting in devastating loss of life and injuries.
Following the attack, an inquiry revealed serious shortcomings in the venue’s security planning and a lack of coordination between security personnel and emergency services. Crucially, there were no legal obligations at the time for venues to have formal counter-terrorism plans or training for their staff.
Martyn’s Law aims to close this gap by creating a consistent and proportionate approach to security, depending on the size and nature of a venue.

Key Features of Martyn’s Law
Martyn’s Law introduces a tiered approach to security responsibilities based on the size of the venue:
1. Standard Tier (100–799 capacity)
This applies to smaller venues such as pubs, clubs, community halls, and small theatres. These venues will be required to:
• Complete basic terrorism protection training
• Create and maintain a simple terrorism risk assessment plan
• Ensure staff are aware of what to do in case of an incident
2. Enhanced Tier (800+ capacity)
Larger venues—such as stadiums, arenas, music festivals, and shopping centres—will fall under this more stringent category. These venues must:
• Develop detailed security plans and procedures
• Appoint a designated security lead
• Conduct regular risk assessments
• Coordinate closely with local authorities and emergency services
• Run live scenario-based training exercises
• Install or upgrade physical security measures where appropriate
This tiered model ensures that security requirements are proportionate to the level of risk associated with the size and nature of the premises.

Who Is Responsible Under Martyn’s Law?
Martyn’s Law places legal obligations on those responsible for publicly accessible premises, including:
• Event organisers
• Venue operators
• Local authorities (for publicly owned spaces)
• Employers operating at relevant locations (e.g., concert promoters, festival organisers)
These stakeholders must demonstrate preparedness and take appropriate security steps depending on the tier they fall under. Importantly, the law aims not to create unnecessary burdens but to raise a minimum baseline of safety and readiness across the UK.

Implications of Martyn’s Law for Security and Marshal Staff

For on-the-ground staff—such as security guards, stewards, and marshals—Martyn’s Law will introduce new responsibilities and training requirements.
Key responsibilities will include:
• Understanding and implementing emergency procedures in the event of a terrorist threat or attack
• Completing mandatory terrorism awareness training, which will cover topics like identifying suspicious behaviour, evacuation protocols, and lockdown procedures
• Participating in drills and tabletop exercises to ensure readiness in high-pressure scenarios
• Maintaining communication with management and emergency services during events
• Recognising and reporting potential threats, such as unattended bags or unusual behaviour
In effect, Martyn’s Law formalises what should already be best practice in the security industry, placing a strong emphasis on preventive measures and active awareness.

What It Means for Companies Holding Large Events
Companies that organise large-scale public events—concerts, festivals, sports matches, exhibitions—will need to take significant steps to comply with Martyn’s Law. This means going beyond basic health and safety protocols to include robust counter-terrorism strategies.
Key actions companies will need to take:
• Designate a Security and Risk Lead with knowledge of counter-terror planning
• Conduct regular venue-specific threat assessments
• Develop and document detailed response plans, including evacuation, lockdown, and communication strategies
• Engage external security consultants where necessary to assess vulnerabilities
• Train all staff and contractors on counter-terrorism procedures
• Install or enhance surveillance systems, barriers, and access control mechanisms
These measures are not just a legal requirement—they also build public confidence. Attendees increasingly expect that safety is being taken seriously, and compliance with Martyn’s Law can be seen as a badge of responsibility and professionalism.

Enforcement and Penalties
The UK Government has committed to ensuring effective enforcement of Martyn’s Law. This means:
• Spot checks and compliance audits
• Fines and enforcement actions for non-compliant venues
• The creation of a new Inspectorate of Protective Security to oversee implementation and provide guidance – part of the SIA role.
However, the approach is intended to be supportive rather than punitive, especially in the early stages. Many venues will receive guidance and transitional support as they adapt to the new regulations.

Let’s honour Martyn’s legacy by making every event a safer space.
Martyn’s Law represents a watershed moment for public safety in the UK. It enshrines in law a principle that is as simple as it is powerful: if you open your doors to the public, you must take reasonable steps to keep them safe.
The memory of Martyn Hett and all those lost in Manchester will live on through this law, as venues and organisations across the UK commit to ensuring that such a tragedy is never repeated.
For venue owners, security professionals, and event organisers, now is the time to prepare, train, and plan. Martyn’s Law is not just about compliance—it’s about taking responsibility, empowering staff, and ultimately, saving lives.
If you operate or work in a venue that could be affected by Martyn’s Law, it’s essential to start preparing now. Familiarise yourself with the guidance, seek out training opportunities, and begin conversations with your security teams and local authorities.
