Workplace media turns its attention to preparing for Martyn's Law

HR Magazine has run a piece encouraging organisations to begin preparing their workplaces for Martyn's Law. The law's everyday name refers to the Terrorism (Protection of Premises) Act 2025, which received Royal Assent on 3 April 2025. Coverage like this is a sign that the topic is moving up the agenda across many sectors, not just the obvious public venues.

The duties under the Act are not yet in force. Commencement is expected in spring 2027, and the exact date is still to be confirmed. So nothing is enforceable right now. But the early attention from workplace and HR commentators is a reminder that preparation takes time, and that staff awareness will play a part in how a venue gets ready.

Premises where 200 to 799 people may reasonably be expected at the same time fall into the standard tier. Those expecting 800 or more fall into the enhanced tier. The count includes staff as well as visitors. Pubs, churches, halls, cinemas and event spaces should work out roughly which tier they are likely to sit in.

Treat this as a prompt to familiarise yourself, not to panic. Get a sense of your likely capacity and tier. Talk to colleagues so the right people understand what's coming. Keep an eye out for official detail from the Security Industry Authority, whose notification process is not yet live. There is time to prepare calmly before the duties begin.
