What is Martyn’s Law? Preparing your Premises for the New Terrorism (Protection of Premises) Act 2025

What is Martyns Law - The Background

We were recently asked by one of our customers, ‘What is Martyns Law?’ It’s an important question as it will effect every premises or venue holding an event of over 200 people. So we thought we’d provide a full run-down on the new legislation to help you understand exactly what it means and how it may or may not affect you.

Essentially, Martyn’s Law was introduced following the terror attacks at the Manchester Arena in 2017, in which 22 people were killed including 29 year old Martyn Hett. His mother, Figen Murray campaigned tirelessly for a change in the law to provide better public protection against future terror attacks.

The Terrorism (Protection of Premises) Act 2025, also known as Martyn’s Law, delivers the Government’s manifesto commitment to strengthen the security of public premises and events.

What Will Martyn's Law Do?

The Act will make individuals working at premises and events responsible for minimising the impact of a terrorist attack. It is intended to improve security in qualifying public places such as arenas, large event venues and schools, with the implemetation of evaculation plans to reduce vulnerability during potential terrorist attacks.

Why Do We Need It?

It has become increasingly apparent that there is a lack of consistency from premises controllers of event venues and public buildings when it comes preparedness and protective security in the event of a terrorist attack. Martyn’s Law will now tighten these procedures and ensure that maximum safety is provided, therefore preventing future devastation, the likes of which was seen at the Manchester Arena bombings.

Who Will The Law Apply to?

The law applies to all premises who fall into the following two tiers;

Standard tier – Smaller premises where 200 – 799 individuals may be present. They will be required to conduct straight-forward, inexpensive procedures, designed to ensure those working at the premises or events are better able to reduce harm and save lives in the event of an attack. These activities include locking doors, closing windows and shutters and identifying evacuation routes. There is no requirement to implement physical measures in the Standard Tier. You must notify the Security Industry Authority (SIA), that they are responsible for the premises. or event. You must have in place, documented procedures proposed to be in place, in the event of an attack.
Enhanced tier – Larger premises or events where 800 or more individuals may be present. In addition to the above, these premises will be required to put in place appropriate measures of protection to reduce their vulnerability to terrorist acts or risks of physical harm to anyone present. For example, metal detection body and bag scanners, CCTV or Access Control and vehicle checks. You must notify the Security Industry Authority (SIA), that they are responsible for the premises or event. In addition, you must have in place, an evacuation plan and documented procedures proposed to be in place, in the event of an attack.

How Does the New Legislation Apply to Schools, Further Education and Childcare Premises?

Enhanced requirements do not apply to education settings because these premises already have existing safety and safeguarding policies and procedures, which effectively establish safety measures and evaculation processes. However, establising a basic legal requirement for procedures is important as these premises can also be subject to attack. While not a legal requirement, some schools have chosen to install ‘lockdown’ systems to improve communication during high-risk situations.

When Will Martyn's Law Come Into Force?

The legislation will not take effect immediately. We expect at least a 24-month lead-in period to allow time to establish the regulator and give those responsible for relevant premises and events enough time to understand, plan for, and meet their new obligations.
