Clearing up common myths about Martyn's Law

The MJ has published a piece aimed at countering misconceptions about Martyn's Law, the everyday name for the Terrorism (Protection of Premises) Act 2025. The Act received Royal Assent on 3 April 2025, but plenty of confusion remains about what it does and does not require. Articles like this reflect the fact that many operators are still forming their understanding of the new regime.

A few myths tend to circulate. One is that the duties are already enforceable — they are not. Commencement is expected in spring 2027, and the exact date is still to be confirmed. Another is that every small venue will face heavy costs. In fact, premises are grouped by how many people may reasonably be expected at the same time: the standard tier covers 200 to 799 people, and the enhanced tier covers 800 or more, with staff included in the count. A third myth is that specific training or equipment is mandatory now; the detail will follow, and the Security Industry Authority's notification process is not yet live.

If you run a pub, hall, church, cinema or event space, this is a good moment to separate fact from rumour rather than react to headlines. Nothing you must do is switched on yet. The sensible focus is understanding which tier your premises is likely to fall into and getting familiar with the broad shape of the regime, so you are not starting from scratch when the rules take effect.

Estimate your realistic peak occupancy, including staff, to see whether you are likely to be in scope. Keep an eye on official updates from the Home Office and the SIA for confirmed dates and detailed guidance. Treat this as familiarisation and readiness — there is no need to rush spending or make big commitments based on unconfirmed claims.
