A new self-assessment tool for Martyn's Law readiness gets a mention

Professional Security Magazine Online has reported on a self-assessment tool designed to help premises prepare for the Terrorism (Protection of Premises) Act 2025, better known as Martyn's Law. Tools like this let operators work through their own situation at their own pace. The details in the report are limited, so treat it as a signal that readiness resources are starting to appear rather than a full account of any single product.

The Act received Royal Assent in April 2025, but its duties are not yet in force. Commencement is expected in spring 2027, with the exact date still to be confirmed. A self-assessment tool is simply a way to think through your premises: roughly how many people may be present at once, who does what, and how you would respond in an emergency. Using one now is about familiarising yourself early, not meeting a legal duty. No tool can certify you or remove risk, and none is approved by the Home Office or the SIA.

Once the duties commence, standard tier will cover premises where 200 to 799 people may reasonably be expected at the same time, and enhanced tier will cover 800 or more. The count includes staff. Knowing which tier is likely to apply to your venue is a sensible first step whichever tool you use.

There is nothing you are required to do yet. If you want to get ahead, make a rough estimate of your busiest expected headcount, and note how your team would react in a serious incident. Keep any assessment you complete as a working document you can revisit as more official detail is published. The SIA's notification process is not yet live, so there is no need to register anything at this stage.
