Martyn's Law

What You Need to Know

Article written by Harrison Beard      |     Fact checked by Darren Gallagher-Viveash (Technical Systems Manager)      |     12th August 2026 

It has become more important than ever for public premises and events to have appropriate security measures in the case of emergency situations.

 

Martyn’s Law was drafted in response to the Manchester Terror Attacks in 2017 to avoid future shortcomings in security and preperations and equip more businesses to do their part in keeping the public safe from emergencies. It became officially recognised on 3rd April 2025 and is expected to be in force when implementation is planned to end in 2027.

 

"Martyn’s Law will help to save lives by making sure venues are ready to act if the worst happens." - Dan Jarvis MBE, Security Minister

 

The legislation will apply across England, Wales, Scotland and Northern Ireland to ensure consistency in keeping the public safe across all parts of the United Kingdom. It applies to any public premises that host 200 or more people at any time, such as hotels, pubs, shops and venues hosting concerts, screenings, conventions or sporting events.

Standard vs Enhanced Tier

 

A premises can be on a standard or enhanced tier, depending on the number of individuals expected to be present at one time. The requirements that a premises must meet differ for either tier, and it is crucial that those responsible for a premises are aware of what tier they fall into and what they have to do in order to comply with the new laws.

 

While not all premises are required to follow Martyn's Law if expected attendance is below 200 people, you should be proactive by future-proofing the growth of your (or a client's) business and venue through implementing the new rules before they are implemented into UK law.
