Helping You Prepare for the Terrorism (Protection of Premises) Act 2025 — widely known as Martyn’s Law

What is Martyn’s Law? 

Martyn’s Law, officially the Terrorism (Protection of Premises) Act 2025, is UK legislation to strengthen public safety by requiring robust counter-terrorism preparedness.

Named in honour of Martyn Hett, who – alongside 21 others – lost his life in the 2017 Manchester Arena bombing, it was secured through the campaigning of his mother, Figen Murray and received Royal Assent on 3 April 2025.

Even though the law is still being developed by SIA and guidance is limited, there is clear direction from the latest review that establishments must be able to do the following:

  • Evacuation: the process of getting people safely out of the premises
  • Invacuation: the process of bringing people safely into, or to safer parts of the premises
  • Lockdown: the process of securing the premises to prevent individuals entering or leaving the premises, e.g. to restrict or prevent entry by an attacker by locking doors, closing shutters or using available barriers
  • Communication: the process of alerting people on the premises to the danger, e.g. providing instructions to remain in place or move away from any danger

How Audiebant  supports this

Audiebant’s system is built around scalable zoning capabilities, so messages can be sent site-wide or targeted to specific areas. In an emergency, you may need to give different instructions to different parts of your site. Zoning makes this possible – guiding people on where to go and which safe exit to use based on their location.  

Authorised users can trigger messages quickly from mobile, desktop or emergency push buttons, whether they are on or off site.

Communication Requirements

Effective emergency communication plans are a vital part of Martyn’s Law. The Counter Terrorism Policing and NSPA (National Protective Security Authority) guidance for announcements encourages:  

  • How Audiebant supports this:
    Crystal-clear, AI-enhanced announcements can be triggered by any authorised user. Our audio-first approach uses AI voice and text-to-speech to ensure clear pronunciation and intelligibility for your emergency messages
  • How Audiebant supports this:
    Audiescreen and Audiebant Clocks displays visual messages alongside your emergency announcements on connected smart boards, laptops, desktops and digital signage, so critical alerts reach people who are deaf or hard of hearing.
  • How Audiebant supports this:
    An intuitive, user-friendly interface makes it easy to send scheduled or live messages tailored to different scenarios. Responses can be triggered instantly via the central control portal, emergency buttons, quick-click wearables and the mobile app, ensuring real-time information reaches the right people without delay.
  • How Audiebant supports this:
    Our professional operations team are on hand to help you get set up and to support you throughout onboarding and ongoing use. Using the system for everyday communications is a highly effective way to keep staff and authorised users familiar and confident, while also delivering strong return on investment.
If 800 or more individuals may be expected, the premises will be an enhanced duty premises unless the Act says otherwise. 
An event that satisfies the following criteria fall within scope of the Act: 
  1. It will take place at premises within section 3(1)(a) of the Act, including land without buildings, that are not enhanced duty premises (or part of enhanced duty premises); 
  2. The relevant premises are accessible to members of the public for the purpose of the event; 
  3. It is reasonable to expect that there will be at least 800 individuals present for the event at once at some point during it;  
  4. There will be measures to check entry conditions are met, such as a ticket checks; and 
  5. The event is not excluded under Schedule 2 to the Act. 

Who will be in scope?

Premises that satisfy the following four criteria fall within scope of the Act: 

  • There is at least one building (or the premises are in a building);
  • The premises are wholly or mainly used for one or more of the uses specified at Schedule 1 to the Act, e.g. a restaurant or a shop;
  • It is reasonable to expect that at least 200 individuals may be present at least occasionally; and
  • The premises are not excluded under Schedule 2 to the Act

How will it work?

The Act establishes a tiered approach, linked to the number of individuals it is reasonable to expect may be present at the same time at premises and events.  

Why act now?

There is currently a phased implementation period of around two years, with organisations expected to be able to demonstrate compliance from around April 2027. 

That means preparation needs to start now. Audiebant is already delivering robust, multi-channel communication systems that support alignment with the new duties, so you’re ready on day one to demonstrate strong preparedness when the Act’s requirements are fully enforced. 

Ready to get ahead?

We can help you design and configure resilient and tailored communications for your site.
