Martyn’s Law
What the new law means for event organisers, and how our team can support your public protection plan on the ground.
Martyn’s Law is the common name for the Terrorism (Protection of Premises) Act 2025. It is named after Martyn Hett, who was killed in the Manchester Arena attack in 2017, and it requires certain venues and public events to be prepared for, and protect people from, a terrorist attack.
The Act received Royal Assent on 3 April 2025, with an implementation period of at least 24 months. The duties are currently expected to come into full effect in spring 2027 — the exact date is still to be confirmed by the government. The Home Office published its statutory guidance in April 2026, and the Security Industry Authority (SIA) will be the regulator.
There’s no legal requirement to comply until the duties come into force — but organisers are being encouraged to start preparing now.
In summary — always check the official guidance for your own event.
Premises and events in scope must notify the SIA.
Plans for what staff do if an attack happens — evacuation, invacuation, lockdown and communicating with the public.
For larger premises and qualifying events: measures to reduce vulnerability to an attack and the risk of harm, documented and kept up to date.
Qualifying public events are held to the same requirements as enhanced tier premises.
Many of our services help put your procedures and measures into practice on the day.
Our team has completed ACT Awareness (Action Counters Terrorism) training from UK Counter Terrorism Policing. They know what suspicious behaviour and items can look like, and how to report them.
Our staff are often the first people visitors meet — at gates, car parks and entrances — which is exactly where that awareness matters.
Controlling which vehicles come onto site, when, and by which route is an important part of protecting crowds. Our traffic and car park teams manage vehicle access, keep vehicles and pedestrians apart, and keep routes clear.
Where traffic needs to be managed on the public road itself, we can also provide CSAS-accredited officers.
If something happens, people need to get out — and emergency services need to get in — quickly. We plan and keep clear the routes your emergency plan relies on, and adjust quickly if a route has to change on the day.
Your protection procedures need to fit the actual site. We produce scaled site plans and CAD layouts showing entrances, exits, car parks, routes and emergency access, which can sit alongside your own plans and paperwork.
A drone gives event control a live view of the whole site: crowds building at entrances, pinch points forming, or an incident developing. In an emergency it helps guide responders to the right place and shows whether exits are clear.
Good communication is at the heart of any emergency response. We can run event control and coordinate radio communications so that everyone on site — our team, your security, stewards and medical providers — can act together quickly.
We coordinate with your security contractor and medical providers so everyone works from one plan. We don’t replace SIA-licensed security — we work alongside it, covering the traffic, parking, site and logistics side of your event.
Every event we work on comes with our own RAMS, written for your site and the services you have booked. We share them ahead of the event so they can sit alongside your own public protection procedures and measures.
The legal duties under Martyn’s Law sit with the person responsible for the premises or event — usually the organiser. We support your plan with trained staff and practical services on the ground, but we are not a Martyn’s Law compliance consultancy, and we don’t provide SIA-licensed security. We’re happy to work alongside the security provider and advisers you already use.
