Our multidisciplinary health and safety solicitors work alongside skilled security industry professionals to provide the knowledge, insight and advice you need to ensure regulatory compliance with Martyn’s Law.

Our suite of proactive legal solutions is designed to significantly reduce the likelihood of serious incidents occurring at your premises or event, as well as subsequent enforcement action by the regulator and criminal prosecution. We can help you to conduct the required risk assessments and security audits and develop bespoke security plans to ensure compliance with the legal obligations imposed by Martyn’s Law. 

While venues and events will have some procedures in place to ensure compliance with similar health and safety regulations, there’s no doubt that time and resources must be dedicated to ensuring compliance with Martyn’s Law. This will include completing the appropriate risk and threat assessments, identifying a comprehensive risk mitigation strategy and preparing and implementing appropriate training plans.

Some organisations will already use the skills of security managers, but sound legal advice and assistance will be necessary to ensure that businesses fully understand and can meet the obligations placed on them by Martyn’s Law. We can provide you with initial advice around whether your premises or an event qualifies for the purpose of Martyn’s Law. We also offer support with compliance monitoring (including penetration testing and live exercises), crisis management and much more.

What is Martyn’s Law?

The Terrorism (Protection of Premises) Act 2025 — commonly named ‘Martyn’s Law’ — seeks to enhance public safety by ensuring better preparedness for and protection from terrorist attacks. Named in tribute to Martyn Hett and 21 others who were tragically killed in the Manchester Arena attack in 2017 — the proposed legislation received Royal Assent on 3 April 2025 and came into force on the same day.

If you operate or manage publicly accessible premises or hold events with a capacity of 200 people or more, the legislation will certainly have an impact on you. A failure to comply with the legislation may result in significant fines, imprisonment and considerable reputational damage — all of which can’t be insured against.

The Bill defines those venues that are subject to the requirements of the legislation as qualifying premises. These include shops, restaurants, bars, hotels, nightclubs, sports grounds, places of worship, hospitals, train stations and schools.

How to prepare — internal review

The starting point for any organisation is to understand and consider the threats and risk posed to premises and events. We work closely alongside security experts to identify areas of compliance with Martyn’s Law and provide assurance to senior management teams that effective systems are in place, while identifying any gaps in compliance that offer opportunities to improve systems and practices. Documenting such assessments will assist organisations in demonstrating that all reasonable steps have been taken to comply with the legislation, which can act as a defence should organisations find themselves the subject of criminal prosecution. 

Following the review, we can assist in preparing a bespoke strategy to implement the necessary changes, taking into account the priority and proportionality of any improvement action. This may include the use of effective on-site security personnel, staff training, updating procedures and equipment and ongoing monitoring of the premise or event security measures. 

We can work with you to ensure that any measures are introduced in an appropriate and cost-effective manner. We’ll also work with you to ensure that your organisation is always ‘inspection ready’, should the regulator attend.

How to prepare — ongoing support & monitoring

Following the initial review and any improvement action, we can provide ongoing reviews, monitoring and support at a frequency to suit you. 

This bespoke service enables your organisation to have on-site, focused advice and support — providing continual reassurance that the premises you’re operating from and events you’re holding continue to comply with Martyn’s Law. The employment of new staff members, changes in the use of premises and the relocation of businesses will require attention to ensure ongoing regulatory compliance. 

Depending on the outcome of the initial status review, we’ll recommend a package of support tailored to your organisation. This approach is intended to upskill your internal teams, including any security staff — quickly getting them to a place where they’re confident and competent to ensure compliance with limited audit and oversight.
