Martyn’s Law (Protect Duty) – UK Legislative Update and Implications

Current Status and Legislative Development

As of March 2025, Martyn’s Law (formally known as the Terrorism (Protection of Premises) Bill) has completed parliamentary stages and is awaiting Royal Assent. Originating from the 2017 Manchester Arena attack, the law introduces a legal duty for venues to implement proportionate measures to protect people from terrorism. After extensive consultation and parliamentary scrutiny, including a Home Affairs Select Committee review, the bill was refined significantly, particularly regarding venue-size thresholds and regulatory clarity. The Security Industry Authority (SIA) has been appointed as the regulatory body. Implementation is expected within two years of Royal Assent.

Reasons for Legislative Delay

The prolonged legislative timeline was largely due to the need for comprehensive stakeholder engagement, ensuring balanced and proportionate obligations across diverse venues. The government prioritised careful consultation with businesses, security experts, and victims’ groups to avoid unintended burdens, especially on smaller venues and voluntary organisations. Extensive parliamentary scrutiny introduced further refinements, ensuring clarity around compliance requirements and regulatory roles.

Role of Local Counter Terrorism Security Advisers (CTSAs)

Local Counter Terrorism Security Advisers have been integral to developing and preparing for the rollout of Martyn’s Law. CTSAs, who traditionally advise venues voluntarily on protective security, will now provide mandated support. They will assist venues with implementing effective security plans, training staff, conducting security drills, and complying with legal duties. CTSAs will collaborate closely with the Security Industry Authority, ensuring venues meet security standards and improving overall preparedness.

Impact on Venue Staff and Different Types of Venues

Martyn’s Law will significantly impact venue staff, with obligations scaled according to venue size (standard or enhanced tiers):

Stadiums and Large Arenas (Enhanced Tier)

Staff at larger venues will need formalised risk assessments and comprehensive security plans. Measures such as rigorous entry screening, crowd monitoring, and emergency procedures (including evacuations and lockdowns) will become standardised, requiring regular training and clear accountability.

Theatres, Concert Halls, Cinemas (Standard/Enhanced Tier)

Mid-sized venues will implement basic protective security measures, including terrorism response plans and staff training. Enhanced-tier venues may also introduce entry screening and more detailed security documentation. Staff training will likely utilise flexible, accessible resources like e-learning provided by Counter Terrorism authorities.

Community Centres and Small Venues (Standard Tier)

Smaller venues, including community halls and places of worship, will introduce simplified emergency response plans, ensuring staff and volunteers are trained in basic counter-terrorism awareness. The law emphasises minimal administrative burdens, requiring simple annual briefings or training sessions.

Outdoor Events and Public Spaces

Event organisers for large public gatherings, such as festivals and marathons, will need clear security plans similar to permanent enhanced venues. Staff will receive training on crowd management, perimeter control, emergency responses, and cooperation with local police and CTSAs.

Martyn’s Law ultimately aims to foster a proactive security culture across all public venues, ensuring staff preparedness and enhancing public safety through proportionate, manageable requirements.
