Martyn's Law Services

Compliance, Risk & Training — prepare now, protect people

Martyn’s Law — officially the Terrorism (Protection of Premises) Act 2025 — will require publicly accessible venues and qualifying events to be prepared for a terrorist incident. 

Duties scale with size: Standard Tier for capacities 200–799 focuses on registering with the regulator and having simple, practised procedures; Enhanced Tier for 800+ adds a documented security plan and measures to reduce vulnerabilities that are reasonably practicable for your site. The Act has Royal Assent and is moving through an implementation period before enforcement begins, so the smart move is to get ready now.

Standard Tier venues must notify the Security Industry Authority (SIA) and have public protection procedures their staff understand and can carry out — evacuation, invacuation/lockdown, clear communications, and quick leadership. Enhanced Tier venues must also assess site vulnerabilities and implement proportionate improvements, keeping a written plan the SIA can review.

1705 Consultancy scopes your portfolio to confirm who’s in scope and which tier, then delivers everything you need: a terrorism risk assessment using our TRAMM model, plain-English emergency procedures, staff training, and documentation that stands up to inspection.

Martyn’s Law applies to any premises or event that is accessible to the public and regularly attracts 200 or more people. If you operate any of the following, you should be preparing now.

Martyn’s Law introduces two tiers of obligation based on venue capacity. Your duties depend on the size of your premises or event.

Standard Tier

200–799 Capacity

Register your premises with the Security Industry Authority (SIA) and put simple, practised procedures in place that your staff understand and can carry out.

  • Evacuation and invacuation/lockdown procedures
  • Clear communication protocols during an incident
  • Staff awareness training so your whole team knows what to do
  • Quick leadership — a designated person in charge when it counts

The focus is on preparedness: knowing what to do if the worst happens and making sure your team does too.

Enhanced Tier

800+ Capacity

Everything in the Standard Tier, plus a structured, documented approach to counter-terrorism preparedness:

  • Carry out a formal terrorism risk assessment
  • Develop and maintain a written security plan
  • Implement measures to reduce vulnerabilities
  • Appoint a designated senior individual responsible for compliance

Enhanced Tier demands evidence-based planning — documented, auditable processes that withstand scrutiny.

Non-compliance with Martyn’s Law can result in enforcement action from the regulator, significant financial penalties, and lasting reputational damage. Beyond the legal consequences, the fundamental purpose of this legislation is to save lives.

Failing to prepare is not simply a regulatory risk — it is a moral one. Organisations that act now will meet their legal obligations and demonstrate a genuine commitment to protecting every person who walks through their doors.

What is Martyn's Law (Protect Duty) or the Protection of Premises Act 2025?

Martyn’s Law, formally the Terrorism (Protection of Premises) Act 2025, is UK legislation designed to improve venue safety at public spaces. Named after Martyn Hett, a victim of the 2017 Manchester Arena attack, it received Royal Assent in April 2025. The law requires venue and event operators to plan for terrorist attacks and implement protective measures.

Martyn’s Law received Royal Assent in April 2025. Full implementation is being phased in, though organisations are encouraged to begin preparing immediately.

The law formalises venue operators’ duty of care. Non-compliance may result in regulatory enforcement, civil liability, reputational damage, and criminal charges in incident situations.

Standard Tier (200–799 people): Basic protective procedures — registering with the Security Industry Authority and having simple, practised evacuation and lockdown plans.

Enhanced Tier (800+ people): All Standard Tier duties plus a documented security plan, vulnerability assessment, and proportionate measures to reduce risk.

1705 Consultancy provides end-to-end Martyn’s Law support including: terrorism risk assessments using our TRAMM model, plain-English emergency procedures, staff training, venue compliance consultancy, vulnerability identification, and documentation that stands up to SIA inspection.

Non-compliance with Martyn’s Law can result in regulatory enforcement by the Security Industry Authority, civil liability, significant reputational damage, and — in the event of an incident — criminal charges.

We support a wide range of venues including concert halls, stadiums, festivals, outdoor events, theatres, cinemas, corporate event spaces, transport hubs, shopping centres, and any publicly accessible venue that meets the Standard or Enhanced Tier threshold.

Organisations should begin preparing now. Despite the phased implementation timeline, starting early allows sufficient time for training, risk assessments, documentation, and embedding procedures into your team’s day-to-day operations.
