Understanding Martyn’s Law – What It Means for Businesses and Public Safety
The Terrorism (Protection of Premises) Act 2025, more commonly known as “Martyn’s Law”, was introduced following the tragic Manchester Arena attack on 22nd May 2017, where 22 innocent people lost their lives and hundreds more were injured. The law is named in memory of Martyn Hett, one of the victims of the attack.
Following the incident, Martyn’s mother, led a long running campaign calling for stronger security measures and improved preparedness at publicly accessible venues across the UK. The campaign highlighted the need for businesses and organisations to better protect staff, visitors and members of the public from potential terrorist threats.
In April 2025, the legislation received Royal Assent, once the 24 month implementation period is complete, it will come into full effect from April 2027. This 2 year period will allow for SIA’s new function to be established and for those who are responsible for premises and events to understand these new obligations.
What Is Martyn’s Law?
Martyn’s Law has been introduced to improve protective security and preparedness at publicly accessible locations and events. The legislation requires certain venues and organisations to take proportionate steps to reduce vulnerabilities and improve their response in the event of a terrorist incident.
The law follows a tiered approach based on venue capacity:
Standard Tier – venues expecting between 200 and 799 people
Enhanced Tier – venues expecting 800+ people
Premises that may fall within the scope of the legislation include:
Schools and educational facilities - schools, universities, colleges, nurseries
Healthcare premises - hospitals, GP’s, dental surgeries
Retail & Leisure - shops, shopping centres, nightclubs
Hospitality venues - hotels, hostels and holiday parks
Entertainment venues - visitor attractions, museums, cinemas, libraries
Sports grounds - stadiums, leisure centres
Places of worship - mosques, churches, synagogues, temples
Public buildings and transport hubs - railways, coach, bus stations
Exemptions:
Primary & Secondary schools are exempt from Enhanced Tier rules and remain in the Standard Tier regardless of size.
Open spaces such as public parks, public gardens
Government buildings
Major international airports and cruise ship terminals
What Does This Mean for Businesses?
Martyn’s Law places greater responsibility on businesses and venue operators to actively consider security risks and have clear procedures in place to help protect people.
Depending on the size and nature of the premises, organisations may need to:
Carry out terrorism risk assessments
Review emergency and evacuation procedures
Improve staff awareness and training
Introduce or enhance security measures
Improve access control and monitoring
Strengthen incident response planning
Ensure communication procedures are in place during emergencies
The legislation is designed to create a culture of preparedness, ensuring organisations are not only compliant but also proactive in protecting people and reducing risks.
