Terrorism (Protection of Premises) Act 2025: Martyn’s Law myth buster
The Home Office has released an official Martyn’s Law myth buster to help organisations prepare for the forthcoming Terrorism (Protection of Premises) Act 2025. This latest guidance addresses common misconceptions about what Martyn’s Law will require in practice - clarifying how duties apply to different venue sizes, what counts as “reasonably practicable” security measures, and how to ensure proportionate preparedness across events, workplaces, and public spaces.
It also explains how the new requirements align with existing safety, safeguarding, and risk-management responsibilities, helping businesses, event organisers, and venue operators focus on practical, cost-effective compliance steps ahead of the Act coming into force.
