Martyn's Law is changing.
We'll help you be ready.
The Terrorism (Protection of Premises) Act 2025, commonly known as Martyn’s Law, will introduce new legal responsibilities for organisations responsible for publicly accessible buildings and events across the UK.
Whether you manage a hospital, university, shopping centre, office, hotel, sports venue or public building, preparing early will make compliance simpler, more effective and less disruptive.
PTSG Fire Solutions helps organisations understand what the legislation means in practice, identify what action is required and implement practical solutions that protect people while supporting compliance.
Understand your responsibilities. Strengthen your preparedness. Protect your people.
What does Martyn's Law mean for your organisation?
Martyn’s Law received Royal Assent on 3 April 2025 and is named in memory of Martyn Hett, who lost his life in the Manchester Arena attack on 22 May 2017. The legislation is the result of the tireless campaigning of his mother, Figen Murray, to improve public safety and preparedness across the UK.
The Act introduces a new legal duty for those responsible for certain publicly accessible premises and events to consider how they would respond in the event of a terrorist attack.
Rather than reacting in a crisis, organisations will be expected to plan ahead. That includes understanding how people would be evacuated, moved to safety, protected through lockdown procedures and kept informed during an incident. Larger venues will also be expected to consider physical measures that reduce their vulnerability to attack.
The Government has committed to an implementation period of at least 24 months from Royal Assent. Statutory guidance was published in April 2026, with the legislation expected to come into force during 2027. Although a commencement date has not yet been confirmed, the direction is clear.
The best time to prepare is now.
Will Martyn's Law apply to your premises?
If you are responsible for publicly accessible premises, it’s worth understanding whether the legislation is likely to apply.
The Act applies where all of the following criteria are met:
There is at least one building, or a building together with surrounding land.
The premises are used primarily for one of the uses listed within the Act, including shops, restaurants, hotels, entertainment venues, sports grounds, healthcare, education and places of worship.
It is reasonable to expect that 200 or more people, including staff, could be present at the same time.
The premises are not specifically excluded under Schedule 2 of the Act.
Public events are also included where 800 or more people are expected to attend and admission is controlled through tickets, passes or payment.
Understanding the two compliance tiers
Standard Tier (200–799 people)
Organisations will need to notify the Security Industry Authority (SIA) and have practical public protection procedures in place, covering:
Evacuation
Invacuation (moving people to safety within the building)
Lockdown
Communication during an incident
The emphasis is on sensible, proportionate preparedness rather than expensive physical measures.
Enhanced Tier (800+ people)
Larger premises and qualifying events will be required to meet all Standard Tier duties, together with additional public protection measures designed to reduce vulnerability.
These include documented procedures, appropriate physical measures where reasonably practicable, submission of information to the SIA and the appointment of a senior individual responsible for compliance.
The SIA will have powers to issue compliance notices, monetary penalties and restriction notices where there is serious or persistent non-compliance, with criminal offences applying in certain circumstances.
Why organisations are preparing now
Although Martyn’s Law is not expected to come into force until 2027, preparation shouldn’t wait.
Developing procedures, reviewing emergency plans and embedding staff training takes time. Organisations that start now will have the opportunity to strengthen resilience, spread investment over a longer period and approach compliance with confidence rather than urgency.
Many organisations already have the foundations in place through existing fire safety arrangements. Martyn’s Law builds on those responsibilities, making now the ideal time to review your wider approach to protecting people.
There are also clear reasons to act today:
Since the beginning of 2020, MI5 and Counter Terrorism Policing have disrupted 19 late-stage attack plots.
The statutory guidance is already available, allowing organisations to understand what good preparedness looks like.
The earlier organisations begin planning, the easier implementation will be.
Our approach
The Home Office is clear that organisations do not need to purchase specific products or appoint consultants simply to comply with Martyn’s Law. No products or services are officially endorsed by either the Home Office or the Security Industry Authority.
We believe that’s exactly the right approach.
Our role isn’t to sell unnecessary systems. It’s to help you understand your responsibilities, review your existing arrangements and recommend practical, proportionate improvements where they genuinely add value.
Sometimes that may involve reviewing procedures.
Sometimes additional training.
Sometimes integrated security or life safety systems.
Whatever your circumstances, our advice starts with what your organisation needs — not what we want to sell.

Frequently Asked Questions
The legislation is expected to come into force during 2027. A confirmed commencement date has not yet been announced.
Only premises where it is reasonable to expect 200 or more people, including staff, to be present at the same time are generally within scope.
Not necessarily. Standard Tier requirements focus primarily on preparedness, procedures and planning. Physical measures become more relevant for Enhanced Tier premises and only where reasonably practicable.
Compliance will be overseen by a new regulatory function within the Security Industry Authority (SIA).
The latest guidance is available through GOV.UK and ProtectUK.
