The United Kingdom has suffered several recent low-sophistication terror attacks at public spaces. This is in addition to the devastation of larger-scale atrocities, such as the Manchester Arena attack. Although terrorist attacks are rare, the threat from terrorism is real and increasingly unpredictable, with public spaces and crowded areas being increasingly viewed as attractive targets.
The targeting of such locations is usually a hostile individual's choice, which cannot always be anticipated. Attacks could potentially occur at any location, and preventing them can prove challenging, highlighting the government’s decision to consider what more could be done to improve public protection.
The Protect Duty will now be known as ‘Martyn’s Law’, in tribute to Martyn Hett who was killed alongside 21 others in the Manchester Arena terrorist attack in 2017. Martyn’s Law is pending UK wide legislation that will place a requirement on those responsible for certain venues and public locations to consider the threat from terrorism and implement appropriate and proportionate mitigation measures.
It will ensure that security preparedness is delivered consistently across the UK, for better protection of the public.
Find out how to prepare for this.
Who will Martyn’s Law apply to?
It is expected that when enacted the new legislation will apply to anyone responsible for venues and publicly accessible locations used for purposes such as entertainment and leisure, retail, food and drink, museums and galleries, sports grounds, public areas of local and central Government buildings (e.g., town halls), visitor attractions, temporary events, Places of Worship, health, and education.
What will Martyn’s Law require you to do?
The government have indicated that venues and publicly accessible locations will follow a tiered model linked to activity that takes place at a location and its capacity.
A standard tier will apply to locations with a capacity of 200 up to 799 people which can undertake low-cost, simple yet effective activities to improve preparedness. This will include:
- Conduct basic terrorism risk assessments to identify potential threats to their premises.
- Develop simple protective measures such as staff training on emergency responses.
- Implement plans for securing the premises during an incident, such as locking doors or creating safe routes.
- Establish evacuation procedures and designate safe areas.
An enhanced tier will focus on high-capacity venues with a capacity of 800+ people, or qualifying events with the same threshold. Organisations in this category will need to:
- Undertake more rigorous risk assessments, potentially with expert consultation.
- Implement advanced security measures like monitoring (CCTV), physical barriers or hiring security personnel.
- Develop and document detailed security plans, including how they will manage and respond to potential terrorist threats.
The government will establish an inspection and enforcement regime, promoting compliance and positive cultural change, and issuing credible and fair sanctions for serious breaches.
The Home Office has shared additional material to support the continued focus on raising awareness about The Terrorism (Protection of Premises) Act 2025, more commonly known as ‘Martyn’s Law’, and building on existing material such as the government factsheets and information on the ProtectUK website. The new resources are available here.

Preparing for Martyn’s Law
Although no date has yet been set for the introduction of the legislation, we strongly advise that you start to implement your own security measures. Consider what you and your colleagues can do to make it harder for a would-be terrorist to carry out a successful attack, by:
- being alert to suspicious behaviour and activity in and around your site, such as people loitering or displaying an unusual level of interest in asking questions, filming or photographing
- assessing the possible vulnerabilities of your site to various attack methods, and taking suitable measures to mitigate the risks
- being security-minded in your communications, particularly online
- encouraging and enabling a security culture at your event and in the workplace, ensuring that any concerns can easily be reported and will be acted upon
- considering how you and your staff would respond to an incident occurring inside, outside, or near to your building or site
- consideration of risk assessments leading to a range of emergency plans and procedures being in place
- undertaking staff training and awareness raising
- employing security systems, processes and measures to mitigate threats
All such efforts are welcome and encouraged to create a culture of security.

See, Check and Notify (SCaN)
See, Check and Notify (SCaN) aims to help businesses and organisations maximise safety and security using their existing resources. Your people are your biggest advantage in preventing and tackling a range of threats, including criminal activity, unlawful protest, and terrorism.
SCaN training empowers your staff to correctly identify suspicious activity and know what to do when they encounter it. The skills your staff learn will also help them to provide an enhanced customer experience. It helps ensure that individuals or groups seeking to cause your organisation harm are unable to get the information they need to plan their actions.
- See - Be aware of what’s happening around you and trust your instincts. If it doesn’t feel right, it probably isn’t.
- Check - You can make a real difference through vigilance and good customer service. Friendly engagement and eye contact can help disrupt a hostile, while improving the customer experience. Do not underestimate the power of saying ‘Hello, can I help you?’. Your intervention may save lives.
- Notify - Find out and learn your site’s security procedures. If you do not know how to report suspicious activity, ask your supervisor.

How to develop a counter terrorism security plan for your event
The challenge faced in countering terrorism is most effectively managed when planning, event management, incident response safety, security, and service are reviewed together.
Event organisers have an obligation under the Health and Safety at Work etc Act 1974 to provide a safe place for their employees to work, and for the visitors to their attractions and events.
Consideration of the risk posed by terrorists must form part of the considerations under this act. It is essential, for corporate governance, to ensure that all threats have been considered, and appropriate measures implemented to manage the exposure to risk. It must be recognised and understood that assessing general event risk is different to assessing security risk. It is essential that the person carrying out this task is competent.
When developing a proportionate plan for an event, it is essential to understand the principles of protective security. The measures should cover the deterring, detecting, delaying, mitigating and responding to an attack. It is not always appropriate to consider all of these aspects, but an understanding of how these work together is essential.
Deter involves discouraging adversaries from conducting an attack by making each element appear too physically or technically difficult to achieve. An example of this could be highly visible security patrols around the outside of the event.
Detect involves being alert to potential attack behaviours at every stage, from planning and reconnaissance to deployment. The deployment of behavioural detection operatives or encouraging staff to be aware of hostile reconnaissance behaviour are examples of detection methods.
Delay involves implementing measures that increase the time it takes for attackers to get to the location of vulnerability once the attack starts. This could be ensuring that the right type of perimeter fencing is used to ensure it is harder to penetrate.
Mitigate involves the use of measures to minimise the impact of an attack. The use of a hostile vehicle mitigation system to prevent vehicular access and provide appropriate stand-off is an example of this.
Respond involves ensuring that measures are in place to respond to an incident. This is crucial in ensuring that harm is kept to a minimum. Appropriate training of response staff and a credible response plan are key to ensuring that any incident is dealt with professionally.
