Join Historic England for the first in a webinar series looking at the application of counter-terrorism security at heritage sites.

This first webinar will introduce The Terrorism (Protection of Premises) Act 2025 – GOV.UK, also known as Martyn’s Law, and how it applies to the heritage sector. With support from the National Counter-Terrorism Security Office, it will also look at the current terrorism threat in the UK, how and where incidents might happen, and the types of threats you may need to protect against.

The Home Office has published Section 27 statutory guidance for the Act. The guidance explains the core concepts of the legislation and helps those responsible for premises and events determine whether they fall within its scope and how to meet their legal duties.

Alongside the statutory guidance, three non-statutory supplementary documents have also been released. The supplementary documents cover:

A.  Methods for assessing the reasonable expectation of individuals present at the premises and events
B.  Scope – illustrative examples
C.  Further resources and learning

Venues that are open to the public and have an estimated capacity at any one time of at least 200 people or host ticketed events with a 800+ capacity will fall in the scope of the legislation. Whilst those that fall within scope of the Act may wish to begin considering the requirements, there is no requirement to comply with them until the legislation comes into force.

The ProtectUK website hosts a range of Martyn’s Law materials, including free online counter-terrorism training.

Museum Development North also has a list of security resources and guidance on its website.
