Coverage points venues to the early steps they can take on Martyn's Law

Published

A Counter Terror Business piece highlights how venues can begin preparing for Martyn's Law. The duties are not in force yet, but there is plenty you can familiarise yourself with now.

What happened

Counter Terror Business has published coverage drawing attention to what premises can do to get ready for Martyn's Law, the everyday name for the Terrorism (Protection of Premises) Act 2025. The piece focuses on practical preparation rather than any new legal requirement. The Act received Royal Assent on 3 April 2025, but its duties are not yet live.

What it means for venues

Nothing is enforceable today. The duties are expected to commence in spring 2027, and the exact date is still to be confirmed. Coverage like this is a useful prompt to start understanding where your venue may sit. Premises where 200 to 799 people may reasonably be expected at once fall into the standard tier; 800 or more is the enhanced tier. The count includes staff.

What to do now

Make a rough estimate of how many people could be on your site at a busy moment, including staff, so you know which tier may apply. Talk it through with the people who run your space day to day. There is no need to register or notify anyone yet — the Security Industry Authority's process is not live.

Keep it in perspective

This is readiness information to help you prepare calmly, not guidance on the law itself or a substitute for professional advice. Use the time before commencement to familiarise yourself, rather than rushing. Preparation now will make the eventual switch-on far easier to handle.

This is our plain-English summary. Read the original in full at Counter Terror Business.
