Martyn's Law Security Readiness
A practical review of role clarity, procedures, escalation, visitor management and supporting controls for sites with public access.
Many public-facing premises already have security in place. The real question is whether the model is clear, current and robust enough to support Martyn's Law readiness in practice.
Having visible security is not the same as being fully ready. For shopping centres, public buildings, mixed-use estates and other public-facing environments, readiness depends on clear roles, practical procedures and controls that work under pressure.
Guidance only — not legal advice or a formal compliance assessment.

Quick answer
Martyn's Law (the Terrorism (Protection of Premises) Act 2025) requires publicly accessible venues with a capacity of 100+ to implement protective security measures. Standard tier (100–799 capacity) venues must have terrorism protection procedures and staff training. Enhanced tier (800+ capacity) venues must also carry out a formal security assessment, appoint a responsible person and produce a written security plan. SPS Security provides practical Martyn's Law readiness support — including reviews, procedure development, guarding, patrols, keyholding, CCTV monitoring and staff awareness — for venues across Hull, Grimsby, Leeds, Doncaster, Sheffield, York, Scunthorpe, Lincoln and the wider Yorkshire and Lincolnshire region. This is practical guidance, not legal advice.
What is Martyn's Law?
Martyn's Law, formally known as the Terrorism (Protection of Premises) Act 2025, is UK legislation introduced to improve protective security at publicly accessible venues and events. Named after Martyn Hett, who was killed in the 2017 Manchester Arena attack, the law places legal requirements on venue operators and event organisers to have security plans in place to protect the public from terrorist threats.
Standard tier and enhanced tier explained
Standard tier — 100 to 799 capacity
- • Implement terrorism protection procedures
- • Provide relevant staff training and awareness
- • No formal written security plan required at this tier
- • Proportionate measures appropriate to the venue's size and risk
Enhanced tier — 800+ capacity
- • All standard tier requirements, plus:
- • Carry out a formal terrorism risk assessment
- • Appoint a designated responsible person
- • Produce a written security plan
- • More comprehensive protective measures
The Security Industry Authority (SIA) is the regulator for Martyn's Law compliance. Failure to comply once the legislation comes into force could result in penalties.
Who does Martyn's Law affect?
The legislation applies to publicly accessible locations with a capacity of 100 or more people. This includes shopping centres, public buildings, entertainment venues, sports grounds, education campuses, healthcare facilities, mixed-use estates, hotels and conference venues, places of worship and other premises where members of the public have access.
What do venues need to do?
Venues in scope must assess their vulnerability to terrorist attack, develop and implement appropriate security procedures, and ensure relevant staff are trained. Enhanced tier venues must also appoint a responsible person and produce a formal security plan.

Why This Matters
Why This Matters
Martyn's Law places greater attention on preparedness, protective security and the ability of organisations to understand and manage risks within public-facing premises.
For many sites, the challenge is not whether security exists. The challenge is whether responsibilities are clear, procedures are understood, escalation routes work in practice, and evidence is available to show that key risks are being managed.
A review can help identify where operational gaps may exist before they become more difficult to resolve.
Start with our Martyn's Law readiness review to assess your current position, or take the quick Martyn's Law awareness check to identify knowledge gaps across your team. Our security guarding service provides SIA-licensed officers trained in protective security for public-facing environments. We have particular experience in education security for schools and colleges, where Martyn's Law obligations are especially relevant. For retail parks and public venues, our team can help you review roles, procedures and escalation in a practical, site-specific way. Speak to our team to discuss a site-specific Martyn's Law readiness review.
Built for Practical Site Review
This guidance is designed for estates, facilities, operations and security teams reviewing real operating models, not just written policies.
The review focuses on practical readiness themes such as role clarity, escalation, visitor management, emergency procedures, reporting, evidence capture and supporting security controls.
It is particularly relevant where public access, shared responsibility, contractors, tenants, visitors and out-of-hours risks all overlap.
Especially Relevant for Public-Facing and Multi-Use Sites
Martyn's Law readiness is particularly relevant for sites where members of the public, staff, tenants, contractors, visitors or service users share the same environment.
This includes shopping centres, retail parks, universities, colleges, large office buildings, commercial estates, healthcare environments, transport-linked sites and other busy public-facing premises.
These sites often involve multiple occupiers, shared public areas, back-of-house routes, service yards, car parks, reception areas, visitor access points and out-of-hours activity. Readiness depends on how clearly landlords, managing agents, facilities teams, security teams, cleaning teams, contractors, tenants and site users understand their roles.
Key areas to consider include entrances and exits, public circulation areas, washrooms, car parks, loading areas, vacant units, reception points, event days, seasonal peaks, control room escalation, tenant communication, contractor access and emergency procedures.
In these environments, preparedness is not just about visible security presence. It is about coordination, role clarity, evidence, escalation and public reassurance.
