What is Martyn’s Law?
A Guide to the UK’s New Terror Protection Legislation.
Martyn’s Law, officially known as the Terrorism (Protection of Premises) Act 2025, is a UK legislation designed to improve security measures in public venues and workplaces. It requires businesses to assess and prepare for potential terrorist threats, or indeed any event resulting in a threat to life, ensuring they have demonstrable systems and procedures in place to mitigate/minimise these threats.
If your organisation operates a venue where the public gathers — from shopping centres and stadiums to schools and places of worship — Martyn’s law may affect you.
Will Martyn’s Law Affect Our Organisation?
Based on the details included in the act, it is estimated that over 250,000 premises will be impacted by the new regulations set out within Martyn’s Law. Any organisation operating one of these premises is now required by law to implement additional security measures.
Publicly Accessible Locations
If the public has access to your premises or part of your premises, with an expected capacity of 200 persons (Standard Tier) or 800 persons (Enhanced Tier), then you will be expected to comply with Martyn’s Law.
Qualifying Activities
If the premises are used for a qualifying activity, such as schools, education establishments, healthcare facilities, entertainment venues, sports grounds, etc, then you will be expected to comply with Martyn’s Law.
Public Events
If you are in charge of any Event (above a maximum capacity of 800) where there are express permission for entry (e.g. ticketing, payment), then you will be expected to comply with Martyn’s Law.
When Does Martyn’s Law Come Into Force?
Martyn’s Law received Royal Assent in April 2025. There is a short implementation period, but businesses will be expected to become compliant by the first quarter of 2027. However, early preparation is strongly advised to avoid last-minute stress — and to protect lives.
