Martyn’s Law – now officially the Terrorism (Protection of Premises) Act 2025 – has passed into UK law. With a 24-month implementation period confirmed, venues and event organisers now have a clear timeline to prepare for new security obligations.

The legislation applies to a broad range of public-facing premises, including hospitality, leisure, healthcare and education sites. Any location where 200 or more people may be present at once is likely to be in scope.

Premises will be categorised under a tiered structure:

  • Standard Tier (200–799 people): Requires a basic response plan, staff awareness training, and registration with the regulator.

  • Enhanced Tier (800+ people): Calls for a formal risk assessment, written procedures, and a designated responsible person.

Detailed guidance from the Security Industry Authority (SIA) is expected during the transition period. However, venues don’t need to wait for every detail before getting started. From due diligence and liability to operational continuity, preparedness is set to influence how risks are assessed and managed.
