Martyn’s Law becomes legislation: what it means for businesses now

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.

A practical step forward in risk management

“Martyn’s Law introduces a more structured approach to managing terrorism risk, but the emphasis is on realistic, proportionate measures. Most venues will already have some foundations in place – this is about formalising plans and ensuring they’re fit for purpose.”, said David Reynolds, Head of Risk Engineering and Surveys at RiskSTOP

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.

“We recommend reviewing occupancy levels and existing procedures now. Even simple actions like updating emergency plans or starting staff briefings can make a meaningful difference.”, said David.

A moment to support readiness

For brokers and insurers, Martyn’s Law will quickly become part of broader risk conversations. From due diligence and liability to operational continuity, preparedness is set to influence how risks are assessed and managed.

Supporting clients to act early not only helps reduce exposure, it also reinforces good practice across the sector.
