The Government has published guidance for businesses on the implementation of Martyn’s Law
The guidance sets out clear steps for businesses. This includes for smaller premises like shops and restaurants with 200-799 people, to ensure evacuation routes are in place, staff know how to swiftly implement a lockdown in their building, and staff know how to quickly communicate with their customers were an attack to occur.
Larger premises and events like concerts and sports stadiums, where 800 or more people will be present, will be required to take further steps to reduce their vulnerability to acts of terrorism – such as having CCTV, bag search policies, or vehicle checks where appropriate.
The Terrorism (Protection of Premises) Act 2025 also known as Martyn’s Law, is named in tribute to Martyn Hett, one of the 22 victims of the horrific Manchester arena attack in 2017
The act will come into effect after an implementation period of at least 24 months from Royal Assent, giving organisations time to understand their new obligations and prepare.
Figen Murray, mother of Martyn Hett said:
This represents another significant milestone for the Martyn’s Law campaign and will provide the clarity for venues and events within scope to begin to implement proportionate measures set out within Martyn’s Law.
We must now ensure everyone is aware of what is required and to make public spaces more secure from the impact of a terrorist attack, so no family has to endure the lasting pain that mine and 21 others have gone through.
