The biggest change to UK public venue security in a generation.
We turn the Terrorism (Protection of Premises) Act 2025 into visual intelligence you can act on: your tier, your vulnerabilities, your team’s plan, mapped on the actual site.
Publicly accessible premises and qualifying events will need to think clearly about how they would respond to a terrorist attack, and larger sites will need to consider vulnerabilities and reasonably practicable measures.
We bring an analyst’s eye to your actual site. Where the gaps are, where lines of sight fail, where mitigation is proportionate and where it’s theatre. The output is a single visual report your team can act on and your board can sign off from, backed by the evidence that produced it.
The Act is not blanket regulation. It is a proportionate response to a hard lesson: publicly accessible places must think more intentionally about how they would respond if the worst happens.
Many venues are open, busy and complex. Multiple entrances, queues, gathering points and predictable patterns of movement, all in plain sight.
Clear procedures, staff awareness and known communication routes reduce confusion during a fast-moving incident, and shave minutes off a response.
The Act uses a tiered approach so expectations are linked to the scale and nature of the premises or event. Not every site needs a fortress.
A short, jargon-free flow to help you understand whether your premises or event may sit in Standard Tier, Enhanced Tier, qualifying-event status, or merits a closer look. Indicative only.
A site or event is publicly accessible if members of the public can enter, with or without payment, a ticket, an invitation or a booking. It is not about whether entry is free or paid, advertised or word-of-mouth. It is about whether the public, broadly, can get in.
Theatres with paid tickets, free public markets, university open days, hotel lobbies, high-street retailers and cathedrals are all publicly accessible. A private members' club, a secured corporate office or a closed staff-only training site is not.
For general guidance only. This tool offers an indicative position based on the answers you give. It is not legal advice and not a regulatory determination. Refer to official Home Office, ProtectUK and SIA guidance when confirming your obligations under the Terrorism (Protection of Premises) Act 2025.
The duty scales with the nature of the premises or event. Most organisations will sit in one of three positions.
You may sit outside the main requirements. Proportionate preparedness can still protect people, reputation and operational continuity if profile, location or activity warrants it.
You may need to notify the regulator and have appropriate public protection procedures in place, so far as reasonably practicable.
You may need to meet Standard Tier expectations and consider additional vulnerability reduction measures, where reasonably practicable.
Indicative only. Final position should be confirmed against official Home Office, ProtectUK and SIA guidance once published in full.
Every qualifying premises and event has a responsible person. They are the individual or organisation accountable for the duty: thinking it through, putting procedures in place, training the team and being able to evidence it. We help them carry that load.
The Act places the duty on a single, named accountable party. For a venue, that is usually the operator or freeholder. For an event, it is usually the organiser with control of the site during the event. The regulatory writing, the procedures and the exercise programme sit with you. So does final accountability.
You are not paid to think like an attacker. We are. We bring the analyst’s perspective to your site: how a hostile actor would view it, where the gaps are, where mitigation is proportionate and where it is theatre. You take that picture into your risk assessment, your procedures and your exercises.
Often the hardest part of the role isn’t knowing what to do. It’s getting it funded. Boards approve what they can see. We give you annotated imagery, indicative cost bands and one-page summaries you can take into the budget meeting and stand behind.
Most organisations do not need another generic checklist. They need to understand how their site actually works, where visibility is poor, how someone could approach, what staff can realistically do and which mitigations are proportionate.
We review your premises, event type, public access, capacity and operational context to help you understand your likely position.
We use mapping, imagery, open-source research and, where appropriate, drone or top-down imagery to build a clear picture of the site.
We identify crowding points, access routes, queues, perimeter weaknesses, line-of-sight issues, hostile vehicle exposure and CCTV blind spots.
Annotated aerial imagery, access maps, range rings, CCTV coverage diagrams, movement routes and proportionate mitigation overlays.
Recommendations decision-makers can understand, prioritise and act on, sized to your tier and your operating reality.
Documented refresh as your site, event, layout or official guidance changes. We stay on the end of the phone in between.
Most Protect Duty plans are text. Ours are drawn on your actual venue: approach routes, stewarding sectors, camera coverage, evacuation and invacuation lines, hostile vehicle mitigation points, all on one page the whole team can see.
When the picture is visual, decisions are faster, briefings are shorter and exercises are sharper.
From a quick tier review to a full Enhanced Tier visual assessment, scoped to where you are now and where you need to be by in-force.
Every engagement closes with a single visual report you can act on. The exact contents are sized to your tier, your site and the questions you actually need answered.
A clear top-down picture of the site as it actually operates.
Annotated overlays of the points that warrant attention.
Where coverage is real and where it is theoretical.
Routes in and out, mapped against operating patterns.
Where people gather, how long for and how exposed they are.
Vector review of approach, speed and standoff.
Unauthorised access points, sightlines and approach paths.
Considerations for moving people away from or into safety.
Visual support for steward and security team placement.
Where talent or principals are part of the picture.
Local crime patterns and recent incidents that matter.
Local mood, tensions and activism likely to shape the day.
Ranked, with indicative cost bands and proportionate options.

We encourage every organisation to read the official guidance directly. The links below are the primary sources we work from.

Visit resource →The Terrorism (Protection of Premises) Act 2025 received Royal Assent on 3 April 2025. There is expected to be an implementation period of at least 24 months before the Act comes into force. Organisations can use that period to prepare proportionately.
In simple terms, Standard Tier generally relates to qualifying premises with expected capacity from 200 to 799. Enhanced Tier relates to larger qualifying premises and events where 800 or more people may be present. Exact obligations should be confirmed against official guidance.
We can help you assess your likely position and prepare proportionately, but we do not provide legal advice or regulatory certification. Final determinations sit with the responsible person and the regulator under the Act.
Not necessarily. Martyn's Law is intended to be proportionate. Many organisations will first need clear procedures, staff awareness and practical planning before considering larger physical changes.
Yes. We specialise in visual security intelligence: annotated imagery, site mapping, vulnerability overlays, CCTV and visibility considerations, movement routes and practical mitigation visuals that decision-makers can actually act on.
Yes. Cazimi is North West based and supports organisations across the UK. Some work is delivered virtually, while site-specific assessments may require imagery, mapping or a site visit depending on the scope.
No. Cazimi provides analyst-led preparedness support and security analysis. Organisations should refer to official Home Office, ProtectUK and SIA guidance and seek legal advice where required.
This page is for general information only and does not constitute legal advice. Cazimi Intelligence & Security provides preparedness support, visual security analysis and analyst-led recommendations. Organisations should refer to official Home Office, ProtectUK and SIA guidance when determining their obligations under the Terrorism (Protection of Premises) Act 2025.
Martyn’s Law preparedness should not be a last-minute paperwork exercise. We help you understand your premises, identify vulnerabilities and build clear, visual, proportionate plans before the legislation comes into force.
