Martyn’s Law, formally the Terrorism (Protection of Premises) Act 2025, is legislation requiring those responsible for certain accessible premises and events to take proportionate steps to protect the public from terrorist attacks. It received Royal Assent on 3 April 2025 and is expected to come into force from April 2027. The Act is named after Martyn Hett, one of 22 people murdered in the Manchester Arena attack on 22 May 2017, and is the result of an eight-year campaign by his mother, Figen Murray. It implements recommendations from Volume 1 of the Manchester Arena Inquiry, published in 2021, and forms part of the Protect and Prepare strands of the UK Government’s wider counter-terrorism strategy, CONTEST.
At United Outcomes, we provide comprehensive support to private-sector organisations in preparing for and complying with the Act’s requirements. Our approach is incremental, helping you define what actions you may need to take and how our solutions will allow you to comply with the legislation.
This consultation forms the starting point that will help your organisation understand your specific responsibilities with respect to Martyn’s law, including considering risk assessment, recording information, developing and implementing security plans, training staff, and emergency response procedures.
The Act establishes a two-tier regime. The standard tier covers qualifying premises where 200 to 799 people may reasonably be expected to be present at the same time, including staff, and focuses on public-protection procedures, staff awareness and notification to the regulator. The enhanced tier covers qualifying premises and events where 800 or more people may be expected, and adds requirements for public-protection measures, a documented public-protection plan, monitoring, and a designated senior individual with personal accountability for compliance.
Three authoritative sources together form the basis for compliance: the Act itself, the Home Office statutory guidance issued under section 27, and the operational guidance issued under section 12 by the regulator, the Security Industry Authority (SIA).
Free supporting resources — including Action Counters Terrorism (ACT) awareness training and sector-specific guidance — are published by ProtectUK, the police-led public-facing arm of the National Counter Terrorism Security Office. The Home Office has been explicit that compliance is designed to be achievable without paid consultancy support, particularly at the standard tier.
The government’s primary resources for Martyn’s Law are the Act’s factsheet (here) and the Protect UK website (here). The Protect UK site has a specific area dedicated to Martyn’s Law (here), as well as many valuable resources.

We have prepared a short assessment to help you determine your organisation’s or venue’s compliance tier by answering a six-question assessment. Participation is free of charge and carries no obligation. Please don’t worry; all information you provide will be treated with the utmost confidentiality.
This assessment will help your organisation prepare for Martyn’s law requirements, including considering risk assessment, recording information, developing and implementing security plans, training staff, and emergency response procedures.
Our expertise helps define vulnerability and your organisation's exposure to risk. We offer training in completing Martyn's Law risk assessments, a platform that shows the completion of risk assessments, recording of compliance, and an auditable system that will satisfy all aspects of compliance. We provide complete online risk assessment tools and simple technology to manage risks. We offer training resources, including practical modules for staff readiness. Our record-keeping system for compliance documentation ensures audit capability. These steps will ensure compliance and enhance safety. All of this is delivered via our user-friendly app.
Through our consultancy service, we offer in-person strategic guidance on Martyn's Law and how risk assessment applicable to larger venues can be applied with suitable mitigation activity. Through this activity, we develop strategies that focus on enhancing public safety within your venues, including crowd management, evacuation procedures, and communication plans. UO's approach ensures that your venue is secure and provides a safe and reassuring environment for the public.
We offer a bespoke solution to your venue as there is significant variation under the requirements of Martyn's Law that apply to both venue and event. It is vital that those carrying out planning and implementation with you have the correct skills and understand counter-terrorism to reach the required compliance.
United Outcome's experts assist in designing and implementing bespoke security plans tailored to the unique needs of your venue, ensuring they meet the highest standards of protection and compliance.
Our plans include physical security measures, access control systems, surveillance, and emergency response protocols to deter and respond to potential terrorist threats.
The regulator, the Security Industry Agency, will have tools to address non-compliance. The SIA will have the power to issue a range of civil sanctions, and the regime is underpinned by relevant criminal offences and investigatory powers. United Outcomes can support you in ensuring that you understand Martyn’s Law legislation and take all necessary measures to ensure compliance with all its aspects. This includes recording risk assessments, mitigating risk, and, where necessary, providing support so that all regulatory matters are addressed.
United Outcomes has partnered with a renowned training provider to develop specific Martyn's Law training relevant to the various roles and responsibilities of those involved in assessing risk and implementing measures to mitigate risk and ensure compliance. We recognise that many small venues will have limited resources to carry out risk assessments and may struggle with an understanding of requirements; we have designed a high-quality, inexpensive, easy-to-use training package that fits within our standard venue platform.
Our Martyn’s Law consultancy offer includes support for venues to complete essential emergency response procedures, including evacuation plans, first aid, and safety measures, tailored to your organisation's specific needs. Venues can then practice, with our support these procedures through simulations and drills, ensuring preparedness.
In the event of a terrorist incident, we offer immediate crisis management support and guide your organisation through the response and recovery process.
Our experts work with you to manage communication, support affected individuals and restore normal operations as quickly and safely as possible.
