SIA Shares Latest Progress on Getting Ready for Martyn's Law

Published

Laura Gibb, the SIA's Executive Director for Martyn's Law, has published an update on how preparations for the new regime are coming along ahead of commencement.

What happened

The Security Industry Authority (SIA), the regulator for Martyn's Law, has posted an update from Laura Gibb, its Executive Director for the regime. The piece sets out progress being made and frames the work as a shared effort between the regulator, venues and the wider public. Martyn's Law is the everyday name for the Terrorism (Protection of Premises) Act 2025, which received Royal Assent in April 2025.

What it means for venues

This is a signpost of direction, not a change to your duties. The Act's requirements are not yet in force, and commencement is still expected in spring 2027 with the exact date to be confirmed. Updates like this show the SIA is steadily building the systems and information venues will need. The notification process is not yet live, so there is nothing to register right now.

A reminder on the tiers

When the duties do begin, the standard tier will cover premises where 200 to 799 people may reasonably be expected at the same time, and the enhanced tier will cover 800 or more. These counts include staff, so it is worth having a rough sense of which tier your venue is likely to fall into.

What to do now

There is no action required today. Use this quieter period to familiarise yourself with the basics and keep an eye on official SIA and GOV.UK updates. Reading the full post via the link below is a good way to stay informed as the picture develops.
