What is Martyn’s Law?

​

Martyn’s Law, also known as the Terrorism (Protection of Premises) Act 2025, was introduced to improve public safety and protective security across the UK.

 

The legislation places a legal duty on organisations responsible for publicly accessible premises and events to assess and manage the risk of terrorism and to implement proportionate safety measures.

​

The law has been introduced following a number of high-profile terrorist attacks and is designed to ensure that venues, organisations, and events are better prepared for potential threats and emergencies.

​

Who Does Martyn’s Law Apply To

​

The Act applies to publicly accessible premises and events where members of the public are present. This includes, but is not limited to:

​

• Education settings

• Healthcare environments

• Leisure and entertainment venues

• Retail and hospitality

• Community and faith settings

• Event venues and organisers

​

The legislation operates under a tiered system based on capacity:

​

Standard Tier

​

Premises or events where 200–799 people may be present at the same time.

​

Enhanced Tier

​

Premises or events where 800+ people may be present at the same time.

Education settings, even where capacity exceeds 800, are generally treated as Standard Tier due to their controlled environments.

​

Smaller premises with fewer than 200 people are currently outside the formal scope of the Act, but are strongly encouraged to adopt proportionate security measures as best practice.
