Martyn's Law - improving safety at public events

About Martyn's law

Martyn’s Law, officially called the Terrorism (Protection of Premises) Bill, became law on 3 April 2025. It aims to improve security and preparedness at public venues and events by helping organisers be better prepared and reduce the impact of potential terrorist attacks.

The law is named after Martyn Hett, who was killed in the Manchester Arena attack in 2017. It is designed to ensure lessons are learned from that tragedy and that venues take steps to keep people safer.

What the law means

Martyn’s Law will apply to certain public places, events and venues. It requires those responsible to:

  • Understand the threat of terrorism
  • Take steps to reduce risk and prepare for emergencies
  • Train staff and have a safety plan in place

The law is not yet in force. The government's timeline for implementation will be at least 24 months before it effect. This gives time for organisers and venue operators to prepare and understand their new responsibilities.

The Security Industry Authority (SIA) has been named as the official regulator and will help oversee how the law is followed.

Do you need to employ third party providers?

No. Premises and event organisers do not need to spend money on consultants to be compliant with the legislative requirements. The government’s statutory guidance will assist in determining whether premises or events are in scope of the legislation and if so which tier they fall within. It will enable duty holders to make their own assessments on how they will meet the requirements of the relevant tier and in turn make an assessment on whether they need to seek further support. Please be aware that neither the Home Office nor the National Counter Terrorism Security Office (NaCTSO) endorse any third-party products or providers in respect of compliance with this legislation.

What event organisers should do now
