Overview

• Martyn's Law, receiving Royal Assent on April 3, 2025, mandates security measures at UK venues to prepare for potential terror attacks.
• Venues hosting 200-799 people must implement basic safety measures, while those with 800+ capacity face stricter requirements like CCTV and bag checks.
• The legislation stems from findings of the Manchester Arena Inquiry, which revealed critical security failures during the 2017 bombing that killed 22 people.
• Figen Murray, mother of victim Martyn Hett, led a six-year campaign for the law, including a 200-mile walk to Downing Street to advocate for change.
• The Security Industry Authority (SIA) will regulate the law, with a two-year implementation period to establish compliance frameworks and support businesses.
