Martyn’s Law – keeping our communities safer

Martyn’s Law, or the Terrorism (Protection of Premises) Act 2025, is new legislation designed to improve public safety by ensuring that venues and events are prepared to respond to the threat of terrorism. It is named in memory of Martyn Hett, one of the victims of the 2017 Manchester Arena attack.

The law introduces a tiered approach to security planning based on the capacity of a venue or event:

• standard tier (200 – 799 people) – needs basic security measures, staff training and notification to the Security Industry Authority (SIA)
• enhanced tier (800+ people)- needs detailed risk assessments, formal security plans and the appointment of a senior responsible individual to oversee compliance

Who it applies to

Martyn’s Law applies to public premises and events where people gather. This includes:

• town and village halls
• community centres
• parks and open spaces used for events
• markets and fairs
• sports and leisure facilities
• libraries and public squares

If your organisation manages or operates any of these spaces, you may have new legal responsibilities under Martyn’s Law.

What you need to do

Depending on the tier your venue or event falls into, you may need to:

• notify the SIA that you are responsible for the premises or event.
• conduct a risk assessment to identify potential threats and vulnerabilities.
• develop proportionate security measures, such as:
  • staff awareness training
  • emergency evacuation plans
  • lockdown procedures
  • safe routes and assembly points

For enhanced tier venues or events, consider additional measures like:

• bag searches
• CCTV and monitoring
• vehicle access controls

Why it matters

While the risk of terrorism in smaller towns and villages may seem low, Martyn’s Law promotes a proactive approach to safety. By preparing for the unexpected, we can reduce harm, save lives, and build public confidence in our community spaces.

Support and resources

We are working closely with the Security Industry Authority (SIA) and local emergency services to support organisations in understanding and complying with Martyn’s Law.
