The Terrorism (Protection of Premises) Bill, also known as Martyn's Law in honour of Martyn Hett who died in the 2017 Manchester Arena attack, will when enacted improve the UK's security by obliging those responsible for certain premises and events to plan how they would respond to a terrorist attack in or near to their property. Persons responsible for larger premises and events must also take steps to reduce the property's vulnerability to terrorist attacks. Premises fall within the scope of the new regime if they are used mainly for qualifying purposes described at section 2 below and, for the standard duty, it is reasonable to expect that from time to time 200 or more people might be on site at the same time. For the enhanced duty obligations to apply instead, it must be reasonable to expect that from time to time 800 or more people would be on the premises at the same time.
From Monday 2nd March 2026 we will have moved offices. Our new address is 3 Stonecutter Street, London, EC4A 4AW.
