The Terrorism (Protection of Premises) Act 2025, Martyn’s Law, requires publicly accessible premises and events to prepare for and reduce the risk of terrorist attacks.
The law is named in tribute to Martyn Hett, one of the victims of the 2017 Manchester Arena attack.
Implementation timeline
The Act got Royal Assent on 3 April 2025. The Act is law now, but it will not be enforced until at least 2027. There's a 24-month implementation period first. This transition allows:
- the Security Industry Authority (SIA) to establish its regulatory function
- the Home Office to publish statutory guidance
- duty holders to plan and prepare for compliance
How it affects Rotherham
Premises and events in Rotherham that are in scope should begin preparing now. Early action will:
- ensure smoother compliance when enforcement begins
- enhance public safety and reduce reputational risk
- align with good practice in counter-terrorism preparedness
What will be in scope
Martyn’s Law applies to publicly accessible premises and events that meet all these criteria:
- used for qualifying activities such as entertainment, retail, food and drink, worship, education
- have a capacity of 200 or more people
- are either permanent premises or temporary events with controlled access
