This week in Martyn's Law

Published

Fresh material from GOV.UK sets out the SIA's role as regulator, how the notification requirement is expected to work, and proposed tribunal rules. Nothing changes what you must do today, but it is worth reading as you prepare.

The SIA as regulator

Two new items explain the role of the Security Industry Authority as the regulator for Martyn's Law. They cover what the SIA is expected to do once the duties are in force and how it will support premises. This is background for now. The SIA's notification process is not yet live, and the duties are not enforceable today. Reading these pieces early helps you understand who you will be dealing with when commencement arrives.

The notification requirement

There is new material on the notification requirement, including an economic note. In broad terms, responsible persons for premises in scope are expected to notify the SIA once the regime is up and running. The detail is still being worked through and the process cannot be used yet. It is useful to know this is coming, so you can plan how you would identify who is responsible for your premises and confirm which tier you fall into.

Factsheets and the Act itself

GOV.UK has published factsheets alongside the text of the Terrorism (Protection of Premises) Act 2025. These are a good starting point if you want the basics in plain terms. As a reminder, standard tier covers premises where 200 to 799 people may reasonably be expected at the same time, and enhanced tier covers 800 or more. The count includes staff. Use the factsheets to sense-check your likely tier.

Proposed tribunal rules

There is a consultation on proposed changes to tribunal rules for applications under section 11 of the Act. This is a technical, legal step about how appeals and applications would be handled. It does not affect your day-to-day preparation, but it shows the wider framework is being built out ahead of commencement.

A collective effort and the timeline

One piece frames Martyn's Law as a shared effort across venues, government and the regulator. That matches the sensible approach for now: familiarise yourself and prepare steadily. Commencement of the duties is expected in spring 2027, and the exact date is still to be confirmed. There is no need to rush. Use the time to understand your premises and get comfortable with the direction of travel.
