The Terrorism (Protection of Premises) Act 2025 gains Royal Assent

Martyn’s Law will deliver increased protection by ensuring public premises and events are better prepared in the event of a terrorist attack.

Premises and events will be better prepared to respond to attacks as landmark legislation known as Martyn’s Law gained Royal Assent and became law today (Thursday 3 April).

This will affect public premises where 200 or more individuals may be present. They will be required to have plans in place to keep people safe and be better prepared in the event of an attack.

Larger premises and events where 800 or more people 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.

‘Martyn’s Law’ is named in tribute to Martyn Hett who was tragically killed alongside 21 others in the Manchester Arena attack in May 2017.
