Understanding Martyn’s Law: A New Era of Public Safety in the UK

The UK Government has passed the Terrorism (Protection of Premises) Act 2025, widely known as Martyn’s Law. Named in memory of Martyn Hett, one of the victims of the 2017 Manchester Arena attack, the legislation represents a major step toward improving the preparedness and resilience of public venues across the UK.

The Act received Royal Assent on 3 April 2025, but it is not yet in force.

The Government has confirmed an implementation period of at least 24 months before the new duties become legally enforceable. This means the earliest possible commencement date is April 2027.

During this period, venues and event organisers are encouraged to begin preparing, but there is currently no legal requirement to comply.

What Is Martyn’s Law?

Martyn’s Law introduces a tiered framework for public premises and events, based on the number of people reasonably expected to be present. Duty holders will be required to take “reasonably practicable” steps to protect the public from the impacts of terrorism.

These steps may include:

  • Developing and maintaining emergency response plans
  • Providing protective security awareness training for staff
  • Installing or upgrading physical security measures where appropriate

The law applies to a wide range of public venues, including entertainment arenas, shopping centres, hospitality venues, places of worship and public attractions.

Two tiers define the level of responsibility:

  • Standard Tier: Premises and events expecting 200–799 people
  • Enhanced Tier: Premises and events expecting 800+ people, with more stringent requirements

The Home Office has published statutory guidance to help organisations understand what will be required once the Act comes into force.
