Law firm publishes a plain overview of Martyn's Law for premises operators
Published
Legal firm Mishcon de Reya has put together a summary of the Terrorism (Protection of Premises) Act 2025. It is a useful recap of the basics while venues get ready for the duties.
What happened
Mishcon de Reya LLP has published an overview explaining the main points of Martyn's Law, the everyday name for the Terrorism (Protection of Premises) Act 2025. The Act received Royal Assent on 3 April 2025. Pieces like this are helpful signposts, though they are not a substitute for the official guidance or your own professional advice.
The basics it covers
The Act splits premises into two tiers based on how many people may reasonably be expected at the same time, including staff. The standard tier covers venues where 200 to 799 people may be present. The enhanced tier covers 800 or more. The Security Industry Authority will be the regulator.
What it means for venues
The duties are not in force yet. Commencement is expected in spring 2027, and the exact date has not been confirmed. The SIA notification process is also not live yet. This is a time to familiarise yourself with the framework, not a moment to panic about enforcement.
What to do now
Work out roughly how many people could be on your premises at once, so you have a sense of which tier may apply. Keep an eye on official updates from the SIA and the Home Office. Reading clear summaries from reputable sources can help you build understanding at your own pace.
