## Key Takeaways For Festival Organisers

- Martyn’s Law (Terrorism (Protection of Premises) Act 2025) introduces two compliance tiers for festivals based on peak attendance: standard tier (200-799 people) and enhanced tier (800+ people), with qualifying events subject to enhanced requirements.
- All festivals must implement four mandatory public protection procedures: evacuation, invacuation, lockdown, and communication. Enhanced tier events also need additional security measures and a formal compliance document.
- Festival organisers must determine their tier by calculating the highest number of people, including staff, expected on site at any single moment, using historic data, ticket sales, and defensible capacity assessments.
- Effective compliance relies on documented, site-specific procedures supported by to-scale site plans, capacity calculations, training records, and evidence that can withstand SIA inspection.
- OnePlan gives festival teams mapping, capacity calculation, and documentation tools that turn Martyn’s Law requirements into practical, inspectable compliance plans.

## Martyn’s Law Tiers For Festivals: How To Determine Your Status

Festival organisers need clarity on whether Martyn’s Law applies and which tier their event falls into. The [Home Office statutory guidance](https://gov.uk/government/publications/the-terrorism-protection-of-premises-act-2025/terrorism-protection-of-premises-act-2025-statutory-guidance) and the [scope (events) factsheet](https://gov.uk/government/publications/terrorism-protection-of-premises-act-2025-factsheets/terrorism-protection-of-premises-act-2025-scope-events) set out the framework. The Security Industry Authority (SIA) is the regulator. Always confirm your specific position with the SIA and your local authority.

The standard tier versus enhanced tier split depends on the highest number of individuals reasonably expected to be present at the same time. That figure includes staff, contractors, stewards, and volunteers. For a festival, it means the peak headcount at any single moment across the entire site. Daily averages and stage-by-stage figures do not meet the threshold.

For festivals, the Terrorism (Protection of Premises) Act 2025 introduces a specific route: the qualifying event. A festival is a qualifying event where all three conditions are met simultaneously:

- As noted in the Key Takeaways, the enhanced tier threshold is 800 or more individuals (including staff) reasonably expected to be present at the same time at any point during the event.
- The event is publicly accessible, so members of the public can attend, even if tickets sell out.
- The event has a well-defined and secure perimeter with entry checks verifying payment, tickets, wristbands, QR codes, or membership.

[The Home Office factsheet](https://gov.uk/government/publications/terrorism-protection-of-premises-act-2025-factsheets/terrorism-protection-of-premises-act-2025-scope-events) gives a worked example. A day festival with 500 people on site until 6pm, followed by 1,000 or more expected later, meets the 800-person threshold because the threshold only needs to be met at some point during the event.

Capacity assessment must be reasonable, evidenced, and defensible. [The Home Office guidance](https://pinsentmasons.com/out-law/news/home-office-martyns-law-venue-guidance) confirms the methodology should draw on historic attendance data, safe occupancy figures, ticket sales, and pre-registration numbers. For a multi-day festival with different day-ticket and camping populations, the relevant figure is the highest number of individuals on site at any single moment across all days. Averages, per-stage figures, and per-zone figures all understate the peak.

The open-access exemption often confuses festival organisers. [Schedule 2 to the Act](https://gov.uk/government/publications/the-terrorism-protection-of-premises-act-2025/terrorism-protection-of-premises-act-2025-statutory-guidance) excludes parks, gardens, and other open-air premises used for recreation or leisure, but only where they are open-access premises without measures to secure or check that access is restricted. A festival with ticketed entry and a secure perimeter is a controlled site, even on open land or in a public park, and can be a qualifying event when the three conditions above are met. A free festival with an open, uncontrolled perimeter and no entry checks falls outside the qualifying event definition regardless of attendance.

Some festivals take place at sites that already qualify as enhanced tier premises in their own right, such as permanent racecourses or showgrounds. In that case, the event is not a separate qualifying event. The premises operator remains the responsible person and must ensure procedures and measures are appropriate for all activities on site.

[The notification requirement guidance](https://gov.uk/government/publications/terrorism-protection-of-premises-act-2025-notification-requirement) confirms that once the Act commences, responsible persons for qualifying events must notify the SIA within 14 days of the event date being first publicised.

[OnePlan’s Martyn’s Law Explained guide](https://oneplan.io/articles/what-is-martyns-law/?utm_term=martyns-law-festival-safety&utm_campaign=ai_growth_agent) covers the broader scope of the Act for event organisers, while [Martyn’s Law for Events: What Organisers Must Do](https://oneplan.io/articles/martyns-law-public-events/?utm_term=martyns-law-festival-safety&utm_campaign=ai_growth_agent) sets out the full obligations once you have confirmed your tier.

## The Four Martyn’s Law Procedures On Festival Sites

Martyn’s Law requires four procedures, and festival teams need to see how each one works on a temporary site with open perimeters, multiple stages, camping fields, and heavy contractor movement. This section translates those procedures into festival reality.

![Festival planning example inside OnePlan: the base layer is a zoomable satellite or street map, and everything placed on it (tents, stages, crowd barriers, toilets, vehicles, staff, signage, routes) stays accurately to scale as you zoom](https://cdn.aigrowthmarketer.co/1780620510054-c5429587ebad.png)**Festival planning example inside OnePlan: the base layer is a zoomable satellite or street map, and everything placed on it (tents, stages, crowd barriers, toilets, vehicles, staff, signage, routes) stays accurately to scale as you zoom**

### Evacuation

[The Home Office statutory guidance](https://gov.uk/government/publications/the-terrorism-protection-of-premises-act-2025/terrorism-protection-of-premises-act-2025-statutory-guidance) defines evacuation as moving people out of the premises or event, or part of it, away from danger. On a festival site, that means zone-by-zone evacuation across multiple stages, camping fields, and open perimeters. Assembly points and egress routes change as the site is built and struck, so the plan must be updated continuously.

In OnePlan, a festival team maps evacuation using crowd areas to define each zone. Crowd barriers and fencing show the physical perimeter and internal divisions, while points of interest mark entrances, exits, assembly points, and first aid locations. The crowd capacity calculator for standing crowd areas gives a defensible figure for how many people each zone holds at any given density. That figure is critical for planning which egress routes need to handle which volumes. OnePlan calculates standing crowd capacity only, not seated.

**With OnePlan, you can place barriers, tents, and more inside its integrated, live planning tool**

A festival site changes between build, live event, and strike. Evacuation routes that are clear on day one may be obstructed by contractor vehicles on day three. A live, to-scale plan in OnePlan reflects those changes as they happen, so the evacuation map stakeholders use stays current.

### Invacuation

Invacuation means moving people to a place within the premises or event where there is less risk of physical harm, including bringing people in from outside or moving them between parts of the site. On a festival site, that means moving people into tents, marquees, and temporary structures. Because those structures may shift location year to year, the invacuation plan must be rebuilt for each event.

In OnePlan, invacuation planning uses the tents and marquees object library to place every structure accurately to scale. Points of interest mark designated safe areas within those structures. Workforce dot planning places security, medical, police, fire, and steward roles at the locations where they will direct people during an invacuation, so every stakeholder can see who is responsible for each zone.

![Workforce planning example inside OnePlan: the base layer is a zoomable satellite or street map, and everything placed on it (tents, stages, crowd barriers, toilets, vehicles, staff, signage, routes) stays accurately to scale as you zoom](https://cdn.aigrowthmarketer.co/1780620462793-34a56c1c38c8.png)**Workforce planning example inside OnePlan: the base layer is a zoomable satellite or street map, and everything placed on it (tents, stages, crowd barriers, toilets, vehicles, staff, signage, routes) stays accurately to scale as you zoom**

### Lockdown

Lockdown means securing the premises or event to prevent individuals entering or leaving. A fenced festival site has multiple gates, contractor access points, and thousands of people who need clear instructions. Lockdown therefore requires a clear, mapped plan that every gate team and security role can act on immediately.

In OnePlan, lockdown planning uses crowd barriers and fencing to show the full perimeter. Points of interest mark every gate and access point, and workforce dot planning assigns security and steward roles to specific gates. When a lockdown is called, every person on the plan knows their position and their responsibility.

### Communication

Communication means providing information to people on the premises or at the event, alerting them to danger, and providing instructions where it is safe to do so. On a large, noisy, multi-zone festival site, getting instructions to stewards, security, contractors, vendors, and campers at the same time is a major operational challenge.

In OnePlan, communication planning uses points of interest to mark information points across the site and workforce dot planning to assign communication roles to every team member. Live, view-only share links mean every stakeholder, from the site manager to the local authority safety officer, always sees the latest version of the plan without anyone resending files. That single source of truth turns communication procedures from theory into practice.

## Festival-Specific Risk Assessment Under Martyn’s Law

A Martyn’s Law risk assessment for a festival must reflect the realities of a temporary, multi-zone site rather than a fixed venue. Site layout, crowd flow, camping, contractor access, open perimeters, multiple stages, and variable capacity across the event all shape risk. For a full methodology, see [Martyn’s Law Risk Assessment: The 2026 Guide For UK Venues](https://oneplan.io/articles/martyns-law-risk-assessment/?utm_term=martyns-law-festival-safety&utm_campaign=ai_growth_agent). This section focuses on festival-specific elements.

A to-scale, map-based plan supports the risk assessment by showing exactly where infrastructure, staff, and crowds sit relative to each other. When a stage, a camping field, a contractor compound, and a public entrance all appear accurately on the same live map, the spatial relationships between them become visible. The risks that emerge from those relationships then become documentable.

OnePlan’s area and perimeter calculator gives defensible figures for zone sizes and perimeter lengths. The crowd capacity calculator for standing crowd areas gives defensible figures for how many people each zone can safely hold at a given density. Both outputs are exportable and can form part of the evidence base for a Safety Advisory Group or SIA inspection.

Contractor churn is a festival-specific risk that permanent venues rarely face. A festival site may have hundreds of contractors on site during build, with different access rights, briefing levels, and knowledge of the site layout. A live plan that shows contractor access points, compound locations, and workforce roles helps the responsible person demonstrate that contractor management forms part of the public protection procedures.

Always follow the guidance of your local authority, fire service, police, licensing authority, and Safety Advisory Group. OnePlan helps teams plan and document. It does not replace the regulatory and advisory relationships that govern festival safety in the UK.

The [Bearfoot Productions case study](https://www.oneplan.io/case-studies/how-bearfoot-productions-scaled-from-small-events-to-10000-capacity-festivals-using-oneplan/?utm_term=martyns-law-festival-safety&utm_campaign=ai_growth_agent) shows how a festival production company uses OnePlan’s crowd capacity and measurement tools to plan 10,000-capacity events with confidence, completing a new festival design with only two site visits.

## Enhanced Tier Security Measures On Festival Sites

Enhanced tier festivals and qualifying events must meet public protection measures relating to monitoring, movement, physical safety and security, and security of information, in addition to the four procedures. For a festival site, that translates into access control, bag checks, CCTV coverage, and vehicle mitigation.

Each of these measures is a spatial planning problem as well as a security one. Vehicle mitigation placement relative to the main entrance determines whether it protects the queue or only the site interior. The layout of access control points and bag-check lanes determines queue length and dwell time. CCTV camera positions relative to crowd areas and perimeter gaps determine coverage.

OnePlan’s arrival calculator estimates queue length and queue time for ticket checks and security screening operations, so a festival team can model the impact of different numbers of lanes and screening points before committing to an infrastructure order. The exit calculator uses exit width, crowd size, and flow rate to estimate exit capacity. Both are available free at the [OnePlan Arrival Calculator](https://calculators.oneplan.io/arrival?utm_term=martyns-law-festival-safety&utm_campaign=ai_growth_agent) and the [OnePlan Exit Calculator](https://calculators.oneplan.io/exit/calculator?utm_term=martyns-law-festival-safety&utm_campaign=ai_growth_agent).

In OnePlan, enhanced tier security planning uses crowd barriers and fencing to show vehicle mitigation placement and perimeter hardening. Points of interest mark CCTV positions, bag-check stations, and access control points, while workforce dot planning assigns security roles to each position. The result is a single plan that connects each security measure back to the four procedures, showing how CCTV coverage supports the communication procedure and how vehicle mitigation supports lockdown.

The [Stadium (Coventry Moves) case study](https://www.oneplan.io/case-studies/events-and-safety-how-stadium-managed-traffic-for-one-of-the-uks-biggest-events-in-oneplan/?utm_term=martyns-law-festival-safety&utm_campaign=ai_growth_agent) demonstrates how a UK security and traffic management company uses OnePlan to plan complex multi-stakeholder events with 400 individual closures and 110 stakeholders, a similar scale of coordination to enhanced tier festival security.

## What Evidence To Keep: Building Your Festival Compliance Pack

An SIA inspector or Safety Advisory Group will ask for your compliance document and supporting evidence. [Security consultants reviewing the statutory guidance](https://professionalsecurity.co.uk/news/interviews/martyns-law-the-musts-shoulds-and-coulds) confirm that any information or requirement from the Home Office guidance needs to be thought through, acknowledged, considered, and documented to enable compliance. A setting with no documented procedures, no evidence of staff training, and no record of engagement with the guidance is unlikely to find an SIA inspection straightforward.

The evidence pack a festival responsible person should be building now includes:

- Documented procedures for evacuation, invacuation, lockdown, and communication, specific to the festival site layout.
- Staff and contractor briefing records showing that all relevant personnel have been made aware of the procedures and their individual roles.
- Training records, including completion of ACT Awareness training or equivalent, for all relevant staff.
- The site plans and capacity calculations that underpin the procedures, showing zone sizes, crowd capacities, egress routes, and security measure placement.
- For enhanced tier and qualifying events: a compliance document setting out all procedures and measures, with an assessment of how each reduces vulnerability and the risk of physical harm.
- Records of tabletop exercises, walkthroughs, or drills used to test the procedures.

OnePlan produces much of this evidence directly from the planning process. High-resolution, print-ready map exports up to A0 size produce site plan documentation suitable for printed materials and event handbooks. The auto-generated Bill of Quantities exports to Excel or CSV as a structured inventory of every object on the plan, including crowd barriers, fencing, tents, and workforce roles. That export serves as a run sheet, load-in and load-out list, and procurement record at the same time. Live, view-only share links mean every stakeholder always sees the latest version of the plan, so no one works from an outdated copy.

The [Jockey Club](https://www.oneplan.io/case-studies/how-the-jockey-club-plans-large-scale-racing-festivals-with-oneplan/?utm_term=martyns-law-festival-safety&utm_campaign=ai_growth_agent), which plans the Betfred Derby Festival with over 100,000 attendees and around 6,000 people from 80 contractors across the build, live event, and de-rig, describes OnePlan as “the gospel of truth”. The platform acts as a single live masterplan that serves as the compliance record for a site of that complexity.

## Operational Security Vocabulary For Festival Teams

Festival teams also need a shared operational security vocabulary that aligns with Martyn’s Law requirements. The definitions below show how common security frameworks connect to your procedures and your site map.

### The 5 C’s Of Event Security

Event security teams often use a five-step framework to respond to a suspicious item or incident: confirm the threat is real, clear the immediate area, establish a cordon, check for secondary devices or threats, and control access to the scene. Under Martyn’s Law, these response steps map directly onto the lockdown and communication procedures. A festival team that has documented its lockdown procedure and mapped its cordon points in OnePlan is turning that response into a form an SIA inspector can review.

### The 4 P’s In Security

[The 4 P’s of counter-terrorism are Prevent, Pursue, Protect, and Prepare](https://www.gov.uk/government/publications/counter-terrorism-strategy-contest-2023), the four work strands of the UK’s CONTEST counter-terrorism strategy. Under Martyn’s Law, the 4 P’s inform the monitoring measures required for enhanced tier premises and qualifying events. CCTV coverage, security patrols, bag checks, and vehicle mitigation each support one or more of the 4 P’s. Mapping those measures spatially in OnePlan shows how coverage is distributed across the site.

### The 4 D’s Of Physical Security

The 4 D’s of physical security are Deter, Detect, Delay, and Deny, though some frameworks substitute “Defend” for “Deny” or expand to five D’s including both. They describe a layered approach to physical security: deterring an attacker from choosing a target, detecting a threat early, delaying an attacker’s progress, and denying access to the most vulnerable areas. Under Martyn’s Law, the 4 D’s underpin the physical safety and security measures required for enhanced tier premises and qualifying events. A festival team that has mapped vehicle mitigation, perimeter fencing, access control points, and CCTV positions in OnePlan has a spatial record of how each layer of the 4 D’s is deployed across the site.

### HOT Protocol For Suspicious Items

[The HOT protocol (Hidden, Obviously suspicious, Typical) is guidance used to assess whether an unattended item is suspicious](https://www.npsa.gov.uk/blog/unattended-or-suspicious-items-steps-take-video), as promoted by the UK National Protective Security Authority and originally devised by the British Transport Police. Under Martyn’s Law, this kind of suspicious-item assessment underpins the communication procedure. Staff must know how to alert people to danger and provide instructions. A festival team that has documented its communication procedure, mapped its information points, and assigned communication roles to workforce dots in OnePlan has the spatial and documentary basis for delivering that guidance across a large, noisy site.

### Spotting Suspicious Behaviour At A Festival

Suspicious behaviour at a festival includes individuals conducting surveillance of entry points, perimeter gaps, or crowd areas. It also includes people who appear nervous, avoid eye contact with security, or behave inconsistently with the crowd around them, individuals leaving bags or packages unattended in crowd areas, and vehicles that approach the perimeter slowly or stop without apparent reason. The National Protective Security Authority (NPSA) publishes the “Recognise, Assess, React” framework for identifying and responding to suspicious behaviour. Under Martyn’s Law, staff awareness of suspicious behaviour forms part of the training requirement for all tiers. A festival team that has mapped security patrol routes and workforce roles in OnePlan gives its security team the spatial context to identify where surveillance activity is most likely and where patrol coverage is most critical.

### Defining A Suspicious Item On Site

A suspicious item at a festival is any unattended bag, package, or object that people nearby cannot account for, that appears out of place for the environment, or that has visible wires, components, or unusual features. Guidance for responding to a suspicious item follows the 5 C’s framework above. Under Martyn’s Law, the evacuation and lockdown procedures must account for the possibility of a suspicious item being found in any zone of the festival site. A festival team that has mapped its zones, egress routes, and cordon points in OnePlan can demonstrate to an SIA inspector that its procedures are site-specific and spatially grounded.

## Your Timeline To Spring 2027: Pre-Commencement Preparation

The Act is not yet in force, and [the statutory guidance](https://gov.uk/government/publications/the-terrorism-protection-of-premises-act-2025/terrorism-protection-of-premises-act-2025-statutory-guidance) confirms there is no legal requirement to comply until the legislation commences. Preparation still needs to start now. The SIA has signalled a proportionate, advisory-first approach to inspections, and [security consultants reviewing the guidance](https://professionalsecurity.co.uk/news/interviews/martyns-law-the-musts-shoulds-and-coulds) advise that responsible persons should have started work on the Act’s requirements by around October 2026, ahead of an April 2027 commencement.

**Now (2026):**

- Start by determining whether your festival is in scope and which tier applies, using the Home Office statutory guidance and the SIA’s online scope tool when available.
- That determination tells you which procedures and measures you must document and how extensive your evidence pack needs to be.
- Once you know your tier, begin documenting the four procedures, specific to your festival site layout, and start mapping your site in OnePlan to create the spatial evidence base for your compliance document.

**Through 2026:**

- Train staff and contractors on the four procedures and their individual roles within each, using your mapped plan as the reference point.
- Run tabletop exercises and walkthroughs to test the procedures against the realities of your site, updating the plan as you learn.
- Refine your capacity calculations and site plans as your 2027 event design develops, so the compliance document reflects the final layout.

**Before Commencement (Spring 2027):**

- Finalise your compliance document and prepare to submit it to the SIA.
- Notify the SIA within the 14-day window described earlier, once your event date is first publicised.
- Ensure your evidence pack, including documented procedures, training records, site plans, and capacity calculations, is ready for inspection.

## Why OnePlan Is The Festival Compliance Planning Tool

Festival site planning often sits between two extremes that do not fully support Martyn’s Law compliance. Manual tools such as PowerPoint, Excel, Canva, Photoshop, Google Maps, or internal static, top-view screenshots and plan files feel familiar and low-cost, yet nothing in them is to scale and plans fragment into emailed versions that nobody can trust. Complex engineering software such as CAD, AutoCAD, Bluebeam, or Revit is accurate but expensive, built for engineers, and carries a learning curve that most festival operations teams cannot absorb.

OnePlan provides an accurate, easy, and affordable middle option. It is a browser-based platform where a festival team drags and drops accurate, map-based objects onto a live satellite or street map, runs intelligent crowd and traffic calculations, and collaborates with every stakeholder on a single live plan. It has powered **200,000 events in 150 countries**, from small community festivals up to the Olympics.

For Martyn’s Law compliance specifically, OnePlan gives festival teams:

- A to-scale, live map of the entire festival site, including stages, camping fields, perimeter fencing, access points, contractor compounds, and workforce roles, which serves as the spatial foundation for all four procedures.
- The crowd capacity calculator for standing crowd areas, giving defensible capacity figures for every zone on the site.
- The area and perimeter calculator, giving defensible measurements for zone sizes and perimeter lengths.
- The Arrival Calculator, which models how attendees enter an event, including crowd flow and potential bottlenecks during ingress. The Exit Calculator models attendee departures and forecasts crowd flow as people leave a site.
- Workforce dot planning for assigning security, medical, police, fire, and steward roles to specific locations.
- High-resolution, print-ready map exports up to A0 size, used for sharing with stakeholders, creating event handbooks, and printing large-scale signage.
- The auto-generated Bill of Quantities, exported to Excel or CSV, as a run sheet and procurement record.
- Live, view-only share links so every stakeholder always sees the latest version of the plan.

Existing PDFs, images, drone shots, site plans, and CAD-derived files can be imported into OnePlan once converted to .png. After import, they can be scaled onto the map and built on top of, turning documents that used to sit unused in a folder into reusable, buildable base maps.

Festival case studies show the impact.

## Conclusion: Turn Martyn’s Law Into A Practical Festival Plan

Martyn’s Law is coming in spring 2027, and festivals sit clearly within its scope. The tier thresholds are defined, the four procedures are mandatory, and inspectors will focus on your compliance document and evidence pack. The real challenge for festival organisers lies in turning evacuation, invacuation, lockdown, and communication into workable plans for a temporary city with open perimeters, multiple stages, camping fields, and contractor churn.

OnePlan gives you a practical way to meet that challenge. A single live, to-scale plan maps every zone, every procedure, every workforce role, and every security measure, and produces the print-ready exports and Bill of Quantities that form the evidence pack. The platform is built for the temporary city that is a festival site and is free to start for your first event.
