This week in Martyn's Law: the regulator, the paperwork and the road to 2027

Published

A batch of official material has landed, from the SIA's role as regulator to draft tribunal rules and updated factsheets. Nothing changes what you must do today, but it does sketch out how the regime will work when the duties begin.

The SIA and its role as regulator

Several new items set out the Security Industry Authority's job as the regulator for Martyn's Law. The SIA will oversee how the regime works in practice, but its notification process is not yet live. For now, this is background reading. It helps to know who you will deal with and roughly what to expect, so the picture is familiar when the duties begin. There is nothing to submit at this stage.

Guidance and factsheets

Updated factsheets and explainer material on the Act have been published, alongside a piece framed around keeping up momentum. These are plain-language summaries of the Terrorism (Protection of Premises) Act 2025 rather than the law itself. They are a useful way to check the basics: the standard tier covers premises where 200 to 799 people may reasonably be expected at the same time, and the enhanced tier covers 800 or more, with staff included in the count. Treat these as preparation reading, not a substitute for professional input.

The tribunal and economic detail

Two more technical documents have appeared. One proposes changes to tribunal rules for applications made under section 11 of the Act, which relates to how appeals and challenges would be handled. The other is an economic note on the notification requirement, setting out the expected cost and effort of notifying. For most venue operators these are not action items. They are a sign that the supporting machinery around the regime is being built out ahead of commencement.

The timeline and what to do now

None of this brings the duties forward. Commencement is still expected in spring 2027, and the exact date is to be confirmed. The duties are not in force and are not enforceable now. The sensible response is steady familiarisation: work out which tier your premises is likely to fall into, read the official factsheets, and keep an eye on the SIA as the regulator. There is no need to rush and no deadline to fear yet — just time to prepare calmly.
