Martyn’s Law: Guidance sets out what museums can do to prepare
New guidance from the UK government details how museums, galleries, and other public venues can prepare for Martyn’s Law ahead of its planned implementation in spring 2027.
The Terrorism (Protection of Premises) Act, part of the UK government’s response to the Manchester Arena bombing in 2017, aims to reduce the risk of harm at public premises and events in case of a terrorist attack.
The legislation received Royal Assent in April 2025 and was given a 24-month lead-in period to allow venues and organisations time to prepare.
The guidance is intended to support “proportionate planning” rather than create an immediate compliance requirement. It gives organisations time to understand which tier may apply to them and what practical preparations they may need to make before it comes into law.
The legislation refers to two tiers: a standard tier for venues that can “reasonably expect” between 200 -799 people, including staff, at their busiest times, and an enhanced tier for venues and events expecting upwards of 800 people.
The Security Industry Authority (SIA) is the statutory regulator for Martyn’s Law and will support organisations that are in scope to understand and meet the requirements.
