SIA outlines next steps on Martyn’s Law implementation in September newsletter

The Security Industry Authority (SIA) has provided a further update (23 September 2026) on preparations for Martyn’s Law, highlighting new support tools, guidance and compliance resources being developed ahead of the legislation coming into force.

In a September update, Laura Gibb, the SIA’s Executive Director for Martyn’s Law, said the regulator is continuing to focus on helping organisations understand whether their premises or events fall within the scope of the Terrorism (Protection of Premises) Act 2025 and what steps they will need to take to comply.

The SIA has directed organisations to existing resources on ProtectUK and Home Office guidance, which include flowcharts and case studies designed to help responsible persons determine whether their premises or events are covered by the legislation. The regulator is also developing an online tool to assist with scope assessments, which is expected to be available next year and will be tested with volunteers beforehand.

To support compliance efforts, the SIA is preparing a range of templates and practical resources for both standard-tier and enhanced-tier premises and events. These materials are intended to help duty holders document procedures and measures required under the legislation, although their use will not be mandatory. The templates are currently being tested with security partners and organisations expected to fall within scope.

The regulator is also progressing work on its notification portal, which organisations will use to register and engage with the regulatory framework. The SIA has invited organisations of all sizes to volunteer in testing the new service as development continues.

Martyn’s Law, formally known as the Terrorism (Protection of Premises) Act 2025, was introduced to improve public protection against terrorism by requiring certain public premises and events to be better prepared for potential attacks. The Act is named in memory of Martyn Hett, who was among the 22 people killed in the Manchester Arena attack. The SIA has been designated as the regulator responsible for supporting compliance and enforcing the new requirements.

The legislation is expected to come into force in spring 2027, with the SIA continuing to develop guidance, compliance tools and engagement activities to help organisations prepare ahead of implementation.
