SIA spokesperson tackles the questions venues keep asking about Martyn's Law

Published

An SIA representative has answered some of the most common questions about the Terrorism (Protection of Premises) Act 2025, in a piece picked up by StandOut Magazine. It's a useful sign of where official thinking is heading as venues prepare.

What happened

StandOut Magazine has published a question-and-answer session with Laura Gibb of the Security Industry Authority (SIA), the body set to regulate Martyn's Law. The piece works through some of the questions venue operators and event organisers raise most often about the new duties. The Act received Royal Assent on 3 April 2025, and the SIA has been named as the regulator.

What it means for venues

Coverage like this is helpful because it shows how the regulator is thinking and which points are causing the most confusion. But it is worth remembering the duties are not yet in force. Commencement is expected in spring 2027, and the exact date has not been confirmed. The SIA's notification process is not live yet either, so there is nothing to register today.

A reminder on the tiers

Two tiers will apply. Standard tier covers premises where 200 to 799 people may reasonably be expected at the same time. Enhanced tier covers 800 or more. The count includes your staff, not just customers or attendees. Knowing roughly which tier you fall into is a sensible early step.

What to do now

Use the time before commencement to familiarise yourself with the basics and follow trusted updates. Q&A pieces from the regulator are worth a read, but they are background reading rather than legal guidance. Take a look at the full article via the link, and keep preparing at a steady pace.
