What Does Martyn's Law Mean for Event Security? The Case for Redeployable CCTV

April 2027 is closer than it looks.

The Terrorism (Protection of Premises) Act 2025 - the legislation enacted from the campaign known as Martyn's Law - received Royal Assent on 3 April 2025. The Home Office has confirmed that implementation is expected no earlier than April 2027, following a transition period. That gives responsible persons, event organisers, and the security professionals advising them roughly two years to understand what's required and put it in place.

For installers who work with events clients - festivals, markets, outdoor concerts, sporting events, exhibitions - the implications are significant. Not because the law mandates specific equipment. It doesn't. But because for one very large category of venue, the obvious practical answer to its requirements is something you can already supply.

Let's go through what the law actually says, what it means for outdoor events with no permanent security infrastructure, and why redeployable CCTV towers are the most defensible compliance answer for that category.

What Martyn's Law Actually Requires - Without the Oversimplification

The Act creates two tiers of duty based on the maximum number of people expected to be present at a venue or event at any one time.

The Standard Tier covers premises and events with a capacity of 200 to 799 people. Duty holders at this tier must implement a procedural plan - defined staff roles, communication procedures, and public protection procedures - but are not required to make physical changes to their premises or procure specific equipment.

The Enhanced Tier covers premises and events with a capacity of 800 or more people, OR premises with a capacity exceeding 800. This is the tier that matters most for events security professionals. Enhanced Tier duty holders face a more substantial set of requirements, including the implementation of "appropriate public protection measures" across four areas:

• Monitoring of premises and the immediate vicinity
• Control of the movement of individuals
• Physical safety and security of the premises
• Security of information

Under the monitoring requirement, official GOV.UK Enhanced Duty guidance explicitly names CCTV as an example of a qualifying monitoring measure. It sits alongside other listed examples: security personnel, communication systems, and detection technology.

This is an important legal distinction. The Act does not mandate CCTV. The operative language throughout the legislation is "appropriate and proportionate" measures and compliance "so far as reasonably practicable." What constitutes appropriate and proportionate will depend on the specific venue or event - its layout, its capacity, its existing infrastructure, the nature of the public facing activity, and a threat assessment.

For a permanent indoor arena with fixed cameras already installed, the CCTV obligation may already be met. For a temporary outdoor festival site with 15,000 attendees and no permanent infrastructure at all, the calculation looks very different. And that gap is exactly where installers come in.

The Problem Outdoor Events Cannot Ignore

The security challenge that Martyn's Law creates for outdoor events is not primarily financial or procedural. It's infrastructural. Most outdoor event sites - festival fields, temporary markets, sporting events on public land, outdoor concerts in parks - have no fixed security infrastructure at all.

There are no permanent CCTV cameras covering entry and exit points. There are no pre-installed cabling routes. There is no mains power connection available for a temporary camera installation. The perimeter changes with every event, the footprint shifts, and the layout of crowd movement is determined weeks before a fixed camera position would make sense to specify.

For event organisers facing Enhanced Tier obligations for the first time, this creates a practical challenge that fixed-infrastructure solutions cannot resolve. You cannot mount cameras on walls that don't exist. You cannot run cable across a field. And you cannot ask a contractor to build a permanent installation for a site that hosts one or two events a year.

The answer to that challenge already exists in the redeployable CCTV tower category - specifically in autonomous towers that require no infrastructure, deploy in hours, cover large open footprints with 360° camera visibility, and can be repositioned between deployments as layouts change.

The event organiser's question isn't "should we have CCTV?" It's "how do we have CCTV on a site that doesn't support it?" That's a question installers can answer.

What 'Appropriate' Looks Like Under Enhanced Tier

The Act and its associated guidance make clear that compliance is assessed against what is "appropriate and proportionate" and "reasonably practicable" given the nature of the premises and the event. For duty holders preparing their Enhanced Tier submissions, this means building a documented case for the measures they have implemented - or are implementing.

For the monitoring component of that case, CCTV provides the most readily auditable evidence trail. Cameras generate time-stamped footage. ARC-monitored systems generate event logs and alarm response records. Professional deployment with documented commissioning creates a paper trail that demonstrates active, managed security rather than a theoretical commitment to monitoring.

The ProtectUK guidance - the operational implementation resource for Martyn's Law - draws on the CPNI framework for security planning at public venues. The consistent theme: measures must be implementable, evidenced, and regularly reviewed. A solar tower that stops recording in winter doesn't meet "regularly reviewed" in any meaningful sense. A fully monitored, BS 8418:2021-compliant tower with documented uptime and weekly remote check-ins does.

For outdoor event deployments specifically, the compliance case for premium-tier redeployable CCTV is strong on three grounds:

Coverage without infrastructure. A tower covering a 360° field of view from a 6-metre mast, repositionable without groundworks, is the only viable monitoring solution on most temporary event sites. Fixed alternatives either don't exist or would require capital expenditure disproportionate to an annual or seasonal event.

Evidential continuity. 24/7 HD onboard recording with a minimum 30-day retention period, BS 8484:2022-compliant ARC monitoring, and time-stamped remote check-in records provide the documented evidence trail that an Enhanced Tier assessment will require. There is no gap in the record that a duty holder needs to explain away.

Availability when it matters. Events don't always fall in summer, and they don't always give six weeks of notice. Easter bank holiday deployments, Christmas markets, winter sporting fixtures - the reliability challenge for event security isn't summer: it's autumn and winter, when solar-only towers begin to struggle and the consequences of a monitoring failure are most severe.

This is where Dual Power Plus becomes directly relevant to the events compliance argument. A methanol fuel cell system providing six months of autonomous runtime doesn't have a winter problem. An event organiser who needs documented continuous monitoring for a three-day outdoor event in November has a straightforward answer.

The Compliance Timeline and What It Means Right Now

Implementation is expected no earlier than April 2027 - but the preparation window is now. Here's what that means in practical terms for installers advising events clients.

Duty holders will need to register with the Security Industry Authority (SIA), which is taking on the regulatory role under the Act. The SIA has confirmed it will not charge fees for inspections or notifications. Enhanced Tier duty holders will be required to designate a responsible person, implement their public protection measures, and maintain documentation that demonstrates compliance.

The transition period is exactly that - a period of transition, not a deadline that appears without warning. Event organisers who are planning their 2027 season are planning it now. Security installers and advisers who understand what Enhanced Tier requires - and can propose a practical, costed, documentable answer - will be ahead of the procurement conversation, not chasing it.

Non-compliance penalties under the Act are substantial: up to £18 million or 5% of global qualifying turnover for the most serious failures at Enhanced Tier venues. The risk profile for event organisers is such that "we intended to sort it" is not a defensible position. The installers who help them sort it now are the ones building long-term event security partnerships.

The Availability Argument: Why Emergency Deployments Matter for Events

One of the most overlooked aspects of events security is that the need rarely arrives on a predictable timeline. Festivals get extended licences. Venues get repurposed at short notice. Events run longer than planned. A sporting fixture gets rescheduled. Security requirements that were theoretical six weeks ago become urgent two days before the site opens.

Availability under pressure is where mediocre CCTV tower suppliers fail events clients in exactly the same way they fail construction clients. The tower that was "available" turns out to be committed to another site. The deployment that was "guaranteed" slides by a week. And the event opens without the monitoring coverage it was supposed to have.

The REG Army fleet of 100+ towers, with next-working-day deployment as standard and same-day deployment possible in genuine emergencies, exists precisely to cover those gaps. When a security company needed two towers across two sites over the Easter bank holiday weekend - a Sunday evening call for a Monday morning deployment - the REG Army had it covered. Both sites. Including Peckham on Sunday, on site by 10am Monday. That's what rapid deployment looks like when it's actually delivered rather than just promised.

For sustained deployments - Christmas markets running six to eight weeks, winter sporting seasons, events that roll from one date to the next - the REG Army has delivered continuous operation for eight months and beyond on a single deployment. The fuel cell runtime means the tower doesn't require intervention to stay operational. Weekly remote double check-ins ensure it's performing as expected. The event organiser gets documented uptime. The installer gets a deployment that doesn't generate support calls.

The Installer Opportunity in Plain Terms

Martyn's Law creates a new, legally-framed compliance requirement for a significant number of UK events - every outdoor event or temporary venue expecting 800 or more people. Many of those venues currently have no security infrastructure at all.

The compliance requirement includes a monitoring component. Official guidance explicitly names CCTV as a qualifying monitoring measure. For outdoor events with no fixed infrastructure, redeployable CCTV towers are the only practical solution. And the law requires the measures to be appropriate, proportionate, evidenced, and managed.

That is a description of the service a premium redeployable CCTV supplier delivers as standard: deployment, commissioning, monitoring, documentation, uptime records, and rapid response if something changes. It's not a stretch to meet the requirement. It's a match.

Installers, integrators, and security companies who advise events clients have two years to position themselves as the credible answer to this question. The advisers who are having that conversation in 2025 and 2026 - before every competitor is circling the same clients - are the ones who will own those relationships when the deadline arrives.

The REG Army is built for exactly this kind of deployment. Premium towers, rapid availability, full ARC monitoring, and a supplier who exclusively works with industry professionals - never approaching your end clients directly.
