The Terrorism Protection of Premises Act 2025 commences in 2027. Find out where your venue stands across the four legal pillars in 15 questions.
What is Martyn's Law?
The Terrorism Protection of Premises Act 2025, known as Martyn's Law, places legal public protection duties on those responsible for qualifying premises and events. Named after Martyn Hett who died in the 2017 Manchester Arena attack, the Act received Royal Assent on 3 April 2025 and is expected to commence in April 2027.
The Act creates two tiers based on capacity. Standard tier (200 to 799) requires reasonably practicable steps to reduce vulnerability, including public protection procedures and regulator notification. Enhanced tier (800+) adds documented public protection measures, staff training, regular evaluation, and a designated senior individual.

Frequently Asked Questions
When does Martyn's Law take effect?
The Terrorism Protection of Premises Act 2025 received Royal Assent on 3 April 2025. Commencement is expected to be April 2027, with a 24-month implementation window from Royal Assent.
Does Martyn's Law apply to my venue?
It applies to qualifying premises and events with capacity from 200. Most nightclubs, large bars, music venues, hotels, and event venues will be in scope. Calculate your full-use capacity (including staff, visitors, and contractors at the same time) against the 200 / 800 thresholds.
What are the four legal pillars?
Evacuation (getting people out safely), invacuation (taking people somewhere safer when evacuation is not safe), lockdown (preventing entry by attackers), and communication (alerting people on the premises). Enhanced tier premises must address all four with documented measures, training, and evaluation.
