Martyn’s Law comes into effect in April 2027, requiring UK venues to implement protective measures against terrorist attacks. The Security Industry Authority enforces compliance through regional inspection teams that assess venues’ threat detection and response capabilities.
Regional inspection teams take shape
The SIA (The Security Industry Authority) is building regional inspection teams across Scotland, Northern Ireland, Wales, and England. These inspectors and assessors will be “central to how we support premises and events through clear guidance and proportionate, risk-based decision making,” according to Laura Gibb’s (SIA’s Executive Director for Martyn’s Law) recent update.
For installers, this regional approach signals that compliance expectations will be consistent nationwide. You won’t be dealing with different standards in different areas. Instead, compliance expectations will be applied consistently across the UK. This gives installers a clear framework to work within.
What this means for your installations
The inspection framework being developed will evaluate how effectively venues can detect, respond to, and recover from potential threats. Your alarm systems play a crucial role in the detection phase. However, traditional fire alarm infrastructure often won’t meet Martyn’s Law requirements.
Fire alarm systems are designed for evacuation scenarios. Martyn’s Law situations may require invacuation (moving people to safe areas within the building), lockdown procedures, or selective evacuation. This means venues need mass notification capabilities that can deliver clear, differentiated alerts to different zones.
Standard fire alarm sounders announcing “leave the building immediately” could create dangerous confusion during a lockdown scenario. Enhanced duty premises especially will need systems. These systems must be able to communicate specific instructions to different areas simultaneously.
As outlined in AddSecure’s Martyn’s Law whitepaper, the distinction between fire safety and terrorism protection requires fundamentally different approaches to system design and installation.
The compliance timeline reality
Gibb’s update emphasises the SIA’s “relentless pace” as they work toward implementation. The enhanced duty threshold affects venues with capacities over 800 people. However, standard duty applies to many smaller premises too. Shopping centres, hotels, entertainment venues, and places of worship will all need to demonstrate appropriate measures. They must show how to protect people during a terrorist incident.
Installers who understand these requirements now will be better positioned when venues start reviewing their preparedness plans. Those waiting until 2027 may find themselves scrambling to catch up on both regulatory expectations and customer demand.
As outlined in AddSecure’s comprehensive Martyn’s Law whitepaper, effective preparedness goes beyond traditional fire safety measures. Venues need the ability to communicate clear, timely instructions during rapidly evolving situations, whether that involves lockdown, invacuation, or coordinated response procedures.
AddSecure can help organisations deliver targeted emergency notifications to staff, visitors, and contractors, supporting faster decision-making and more effective incident response.

Q&A
What is Martyn’s Law and when does it come into effect?
Martyn’s Law, formally the Terrorism (Protection of Premises) Act 2025, comes into effect in April 2027. It requires venues to implement protective measures against terrorist attacks, with requirements varying based on venue capacity and risk level.
Who enforces Martyn’s Law compliance in the UK?
The Security Industry Authority (SIA) enforces Martyn’s Law through regional inspection teams across England, Scotland, Wales, and Northern Ireland. Inspectors assess whether venues have appropriate protective measures in place to detect, respond to, and recover from potential terrorist threats.
What is the difference between invacuation and evacuation under Martyn’s Law?
Evacuation moves people out of a building, while invacuation moves people to designated safe areas within it. Martyn’s Law recognises that terrorist incidents may require invacuation or lockdown rather than evacuation. Venues need communication systems capable of issuing different instructions depending on the nature and location of the threat.
How do enhanced duty and standard duty differ under Martyn’s Law?
Enhanced duty applies to venues with a capacity over 800 people and requires more comprehensive protective measures, including advanced notification and response capabilities. Standard duty covers smaller venues but still mandates basic protective procedures and the ability to communicate clearly with occupants during an incident.
How should organisations prepare for Martyn’s Law compliance?
Organisations should assess their current preparedness against the requirements, identify gaps in emergency communication and incident response procedures, and ensure staff understand their roles. Starting now gives time to implement appropriate measures before SIA inspections begin, rather than rushing to catch up closer to the April 2027 deadline.
Why is mass notification important for Martyn’s Law preparedness?
Mass notification enables venues to communicate specific instructions to different groups and areas during an incident, quickly and simultaneously. Standard alarm systems were designed for single-instruction evacuation. Martyn’s Law scenarios often require more nuanced responses, making the ability to issue targeted, real-time communications a key part of an effective preparedness plan.
