Public debate continues over what Martyn's Law can and can't do

Published

A letters exchange in The Times has aired different views on the part Martyn's Law plays in preventing terrorism. It's a useful reminder that the law sits alongside, not in place of, wider security efforts.

What happened

The Times published a selection of readers' letters discussing the role of Martyn's Law in preventing terrorism. Letters pages are opinion and debate, not official guidance. They show that the new law is being talked about widely as it moves towards taking effect. The exact details of each contributor's view are set out in the source itself, which you can read in full.

What it means for venues

Nothing about the law has changed because of this discussion. Martyn's Law — the Terrorism (Protection of Premises) Act 2025 — received Royal Assent in April 2025, and its duties are expected to begin in spring 2027, with the exact date still to be confirmed. Public debate is normal for a measure of this size. For pubs, churches, halls, cinemas and event organisers, it's a signal that awareness is growing, not a new rule to act on.

The bigger picture

It's worth remembering what the law is designed to do: encourage premises to think ahead about how they would reduce harm and protect people. It works alongside police advice and other security efforts rather than replacing them. No single measure removes risk, and the law does not promise to prevent every incident. Keeping that perspective helps separate useful preparation from headlines.

What to do now

There's no action required from this letters page. Use the time before commencement to familiarise yourself with which tier your premises may fall into — standard tier covers places where 200 to 799 people may be expected at once, and enhanced tier 800 or more, including staff. The SIA notification process is not yet live. Calm, early preparation now will make the eventual start date far easier to handle.
