Martyn's Law Compliance for Venues & Events
The Terrorism (Protection of Premises) Act 2025 — known as Martyn's Law — will require many venues and events to be better prepared for a terrorist attack. Westgate helps you understand your obligations and put practical, proportionate measures in place ahead of enforcement.
What Martyn's Law means for you
Martyn's Law is the common name for the Terrorism (Protection of Premises) Act 2025, which received Royal Assent in April 2025. It is named after Martyn Hett, one of the 22 people killed in the 2017 Manchester Arena attack, and was campaigned for by his mother, Figen Murray. The law places a new duty on those responsible for certain public premises and events to take proportionate steps to reduce the risk of harm, and to be better prepared to respond, in the event of a terrorist attack.
The Government has confirmed an implementation period of at least 24 months before the duties take effect — so enforcement is expected around 2027. That window is intended to give those responsible for premises time to understand their obligations and prepare properly. The Security Industry Authority (SIA) will act as the regulator. Preparing early is far less disruptive, and far less costly, than scrambling to comply at the deadline.
The two tiers
Standard tier (200–799 capacity)
Qualifying premises expecting 200 to 799 people must have simple, low-cost procedures in place — covering evacuation, moving people to safety, locking down and communicating with staff and the public in the event of an attack.
Enhanced tier (800+ capacity)
Larger premises and qualifying events expecting 800 or more people must additionally maintain a documented risk assessment, put appropriate security measures in place and designate a responsible person accountable for compliance.
How Westgate helps you prepare
We start with a readiness assessment: a clear, jargon-free review of your premises or event against the requirements of the Act, identifying which tier applies and where the gaps are. From there we help you put the right measures in place — evacuation, invacuation and lockdown procedures, staff awareness and, for enhanced-tier premises, a documented risk assessment and the appointment of a responsible person.
Because Westgate also delivers guarding, canine and CCTV services, we can provide any physical security measures your assessment identifies — giving you a single accountable partner rather than a report you are left to act on alone. Whether you run a venue, manage events or are responsible for a public building, we will tailor practical, proportionate support to your organisation.
Not sure if it applies to you? If your premises or event may see 200 or more people, Martyn's Law is likely to apply. Call us on 0330 043 3995 for a no-obligation conversation and we will tell you where you stand.
