Principal Review and Insights Advisor - Martyn's Law

We are now preparing to take on new responsibilities as the regulator of Martyn’s Law - named after Martyn Hett, one of the 22 people who tragically died on 22 May 2017 in the terrorist attack on Manchester Arena. Martyn’s Law, introduced by the Terrorism (Protection of Premises) Act 2025, is intended to improve protective security and preparedness at premises and events across the UK.

The new Act will require premises in scope to be prepared to keep people safe in the event of an attack. Certain larger premises and events will also need to take steps to reduce their vulnerability to acts of terrorism.

Martyn’s Law is primarily a civil, regulatory regime. We will regulate supportively and proportionately but robustly. The SIA will have new guidance, investigatory and inspection functions and a range of new powers and sanctions. Our new Martyn’s Law functions will sit alongside and complement our existing responsibility for regulating the private security industry.

Job description

Help shape how Martyn’s Law works in practice and make a lasting contribution to public protection.

This is an opportunity to play a pivotal role in the development and continuous improvement of the regulatory approach to Martyn’s Law. As Principal Review and Insights Advisor, you will lead the review and insight activity that helps ensure regulatory guidance is evidence-led, effective and delivers meaningful outcomes across the regulated sector.

Working within the Martyn’s Law Regulator (MLR) Guidance and Review function, you will turn evidence into action. You will draw together learning from inspections, desk-based assessments, stakeholder intelligence, research, the public and wider regulatory activity to identify emerging risks, trends and opportunities for improvement. You will then translate those insights into practical recommendations and high-quality guidance that helps premises and event organisers understand their responsibilities.

This is a role for someone who enjoys tackling complex questions and using sound judgement to reach clear conclusions. You will have significant autonomy to determine the right review and evaluation approaches for novel issues, while working closely with the Head of Guidance and Review and colleagues across the organisation.

Your analysis will have real influence. You will prepare reports, briefings and strategic recommendations for senior leaders, including the MLR Deputy Director and Head of Guidance and Review, helping to shape national guidance, regulatory priorities and interventions. You will also engage confidently with a wide range of stakeholders, from Home Office officials and counter-terrorism partners to local authorities, regulators, professional bodies and representatives of the premises and events sectors.

We are looking for an experienced review, evaluation, assurance or performance improvement professional who can combine strong analytical thinking with excellent communication and influencing skills. You will be comfortable interpreting complex quantitative and qualitative evidence, identifying what really matters, and communicating it clearly to both technical and non-technical audiences.

Experience of working in a regulatory, protective security or counter-terrorism environment would be advantageous, as would knowledge of evaluation methodologies, performance frameworks or guidance assurance.

Above all, you will bring curiosity, sound judgement, collaboration and a commitment to using evidence to drive better outcomes.

Join us and help turn insight into action — improving compliance with Martyn’s Law and contributing to the protection of people across the country.
