What is Martyn's Law and Why Was It Introduced?
Martyn's Law aims to improve security measures in public venues, ensuring a Martyn’s Law, officially known as the Terrorism (Protection of Premises) Act 2025, is a UK legislation introduced to increase public safety by mandating that venues and public spaces assess and address the threat of terrorism. Named in memory of Martyn Hett, a victim of the 2017 Manchester Arena attack, the law enforces a duty of care for owners and operators of premises where the public gather.
Under this act, businesses and event organisers are now legally required to implement security procedures. The aim is to reduce vulnerability to terrorist attacks and minimise harm to the public. The legislation applies to premises based on size and expected footfall, introducing a tiered system of compliance responsibilities.
This law puts the onus on management, rather than policing or government, to proactively identify risks and take counter-terrorism measures seriously. With growing concern over public safety, this law provides a structured framework to reduce exposure and improve response, creating a safer environment for everyone. By implementing this law, organisations can proactively address potential threats and enhance community safety.
