The Home Office has today announced that a new Protect Duty will be introduced through legislation, to be called Martyn’s Law.
The government consulted on proposals to introduce a Duty to Protect in April 2021. This followed lessons learnt from the Manchester Arena attack, in which Martyn Hett and 21 other people were killed in a terrorist attack in 2017.
Listening to feedback from businesses, security professionals and victims’ groups, including Martyn’s mother Figen Murray and the Martyn’s Law Campaign Team, the Home Office propose a tiered framework, with owners and operators of public spaces and venues required to put in place measures to keep the public safe from a terrorist attack, based upon the size of the venue and the nature of activity taking place.
Publicly Accessible Locations
Martyn’s Law will involve a standard tier and an enhanced tier. Both tiers see a requirement for regular training and the production of a preparedness plan.
- A standard tier will apply to locations with a maximum capacity of over 100 people. The aim is to help teams undertake low-cost, simple and effective activities to improve preparedness using existing resources. This will include training, information sharing and completion of a preparedness plan to embed practices, such as locking doors to delay attackers’ progress or knowledge on lifesaving treatments that can be administered by staff whilst awaiting emergency services.
- An enhanced tier will focus on high-capacity locations in recognition of the potential consequences of a successful attack. Locations with a capacity of over 800 people at any time, will additionally be required to undertake a risk assessment to inform the development and implementation of a security plan to assess the balance of risk reduction against the time, money and effort required to achieve a successful level of security preparedness – a recognised standard in other regulatory regimes (including Fire and Health and Safety).
The type of premises and activity in scope to emerging legislation include museums and galleries, leisure, entertainment, shops, restaurants and pubs, sports grounds, public areas (such as receptions and conference rooms) of local and central government buildings, visitor attractions, temporary events, places of worship, health and education facilities.
Martyn’s Law will apply to either a building (including collections of buildings – such as a campus) or location/event (including a temporary event) that has a defined boundary, allowing capacity to be known.
Martyn’s Law isn’t going to stop terrorism, but common-sense security, and making sure venues are doing all they can to keep people safe, could mean fewer suffer what myself and the families of Manchester have had to endure. I welcome the Government’s commitment to including smaller venues and working quickly on this legislation. It is vital we now take the necessary steps to protect ourselves and others wherever possible and I hope other countries learn from this ground-breaking legislation.”

The Government will establish an inspection and enforcement framework to underpin Martyn’s Law, promoting compliance and issuing sanctions for serious breaches.
Dedicated statutory guidance and tailored support will be provided by the Home Office to ensure those places, spaces and venues in scope can effectively discharge their responsibilities. Venues below the standard tier are also invited to adopt the same good practices on a voluntary basis, and learn from larger organisations and venues.
Martyn’s Law will extend to and apply across the whole of the United Kingdom. The Government will publish draft legislation in Spring 2023.
Marble Arch London BID will be supporting our venues in scope when the detailed guidance associated with Martyn’s Law is published. In the meantime, expert advice, training and guidance is available on the online protective security hub, ProtectUK.
