This week in Martyn's Law

Two new items focus on the Security Industry Authority and its role as the regulator for Martyn's Law. They explain what the SIA will do and how it fits into the wider regime. For venues, the useful takeaway is simply to get familiar with who the regulator will be. The SIA's notification process is not yet live, so there is nothing to submit at this stage. This is background reading to help you understand how oversight will work when the duties begin.

There is new material on the notification requirement, including an economic note that looks at its likely costs. This is where premises in scope will let the regulator know they exist. The detail is still being built out, and the process itself has not opened. For now, it is worth understanding the concept and starting to think about which tier your venue might fall into — standard for 200 to 799 people expected at the same time, enhanced for 800 or more, with staff included in the count.

A proposed change to Tribunal rules covers applications under section 11 of the Act. This is a technical, behind-the-scenes step that sets out how certain appeals or applications would be handled. Most venues will not need to engage with it directly. It is a sign that the framework around the Act is steadily being completed ahead of commencement.

The government has published a set of factsheets and a piece framing Martyn's Law as a collective effort. Together these give a plain overview of the Act and stress that preparation is a shared responsibility across venues, staff and partners. They are a good starting point if you are new to the topic. Treat them as familiarisation material, not as legal guidance or a checklist you must complete now.

None of this changes the headline position. The Act received Royal Assent on 3 April 2025, but the duties are not yet in force. Commencement is expected in spring 2027, and the exact date is still to be confirmed. That gives time to read the new material, understand your likely tier, and quietly build readiness. There is no deadline to react to today — the sensible approach is to familiarise and prepare.
