‘Martyn’s Law’ Terrorism (Protection of Premises) Act

Martyn’s Law, officially the Terrorism (Protection of Premises) Act 2025, aims to improve security and preparedness at publicly accessible locations in the UK. It requires certain premises and events to assess and mitigate the risk of terrorist attacks, with different tiers of requirements based on venue size and expected capacity.

The law is named after Martyn Hett, who died in the Manchester Arena attack, and seeks to ensure lessons are learned from that tragedy by requiring venues to take steps to enhance public safety.

Our range of signs and posters have been designed so organisations of all types can demonstrate compliance with Martyn’s Law by doing the simple, affordable and attainable things right.
