Martyn's Law 

Martyn’s Law, officially known as the Terrorism (Protection of Premises) Act 2025, is a new UK law designed to improve public safety by helping organisations prepare for the unlikely event of a terrorist attack. It was introduced following the 2017 Manchester Arena attack and is named in memory of Martyn Hett, one of the 22 people who lost their lives. 

 

 

Martyn’s Law asks organisations a straightforward question: 

 

"If the worst happened, would your staff know what to do?" 

 

The law is not about turning teachers, outdoor instructors or event organisers into security experts. 

Instead, it encourages sensible, proportionate planning so people can respond quickly and effectively during an emergency. 

 

 

The law mainly affects: 

 

 

Requirements vary depending on the size and type of venue or event. Larger venues will have additional responsibilities. 

 

 

For many organisations, preparation could include: 

 

 

The focus is on reasonable, practical measures rather than expensive security systems. 

 

 

Outdoor centres, schools and activity providers already think about risk, safeguarding and emergency planning every day. 

 

Martyn’s Law builds on these existing responsibilities by encouraging organisations to consider: 

 

 

Good first aid, clear leadership and rehearsed emergency procedures are all part of being prepared. 

 

 

The law received Royal Assent on 3 April 2025, but there is an implementation period of at least two years before organisations are legally required to comply. 

This gives venues and organisations time to understand the requirements and prepare appropriately. 

 

Preparedness Matters 

 

Emergencies are rare, but preparation matters. 

 

Whether you're running a school trip, leading an outdoor activity, managing a venue or organising an event, having a simple plan and trained staff can make a real difference. 

 

At Invenio Training, we believe preparedness isn't about fear. 

 

It's about confidence.
