## Key Takeaways

- Martyn’s Law (Terrorism (Protection of Premises) Act 2025) requires UK venues and events to document, test, and evidence four public protection procedures: evacuation, invacuation, lockdown, and communication.
- Standard tier premises (200–799 people) focus on procedural readiness and staff awareness. Enhanced tier premises and qualifying events (800+ people) must also complete a documented risk assessment, install proportionate physical security measures, and submit information to the SIA.
- The responsible person must keep procedures proportionate, test them regularly, and maintain evidence such as training records, rehearsal logs, and a to-scale site plan.
- Procedures must link directly to a live, accurate site plan that shows exactly where invacuation routes, lockdown points, assembly areas, and communication nodes are located.
- OnePlan provides a visual, to-scale mapping platform that helps venues and events document and evidence Martyn’s Law safety procedures using drag-and-drop objects, capacity calculators, and export-ready plans.

## What Are The Four Martyn’s Law Safety Procedures?

The [four statutory public protection procedures](https://www.gov.uk/government/publications/the-terrorism-protection-of-premises-act-2025/terrorism-protection-of-premises-act-2025-statutory-guidance) are evacuation, invacuation, lockdown, and communication. They are sets of actions staff take when they suspect terrorism is occurring or about to occur at the premises, event, or in the immediate vicinity. The guidance does not prescribe a universal route, command structure, or script. Operators must develop procedures that fit their site, people, layout, and risks.

### Evacuation

Evacuation means moving people out of the premises, event, or an affected part to get them away from danger. A documented evacuation procedure should cover six elements.

1. **Trigger and decision authority.** Name the single role with authority to call evacuation and a clear substitution chain for their absence.
2. **Alarm and notification.** Define how staff and visitors are alerted, such as PA, radio, in-person relay, or a pre-agreed phrase.
3. **Primary and secondary routes.** [Fire-safety routes assume the fire is at one end of the building, but a deliberate-harm evacuation cannot make that assumption](https://martynslawsoftware.co.uk/guide/the-four-procedures). Document at least one alternative route per area in case the primary route is unsafe.
4. **Assembly points.** Designate points at a safe distance from the building in more than one direction, away from roads and car parks.
5. **Roll call.** Define how staff and visitors are accounted for, including provisions for people with mobility or sensory needs.
6. **Emergency services handover.** Specify how the responsible person or duty manager briefs police and fire on arrival.

Most operators already hold some form of evacuation plan. Martyn’s Law safety procedures require evacuation to be documented, tier-appropriate, and tested, with evidence for each requirement.

### Invacuation

Invacuation means moving people to a safer place within the premises or event. This can mean bringing people inside from outside or moving people between internal areas when safe. A clear invacuation procedure helps outdoor and semi-open spaces manage external threats.

1. **Decision trigger.** Define when moving people inward is safer than moving them out. This typically applies when an attacker is outside the building or external evacuation routes are compromised.
2. **Designated refuge areas.** [Identify interior rooms with limited external access, solid walls, and securable doors](https://martynslawsoftware.co.uk/guide/the-four-procedures).
3. **Route signage and wayfinding.** Map routes from public areas to refuge areas, including routes for people who may not hear or understand a verbal instruction.
4. **Capacity and welfare.** Check ventilation, wheelchair and hoist accessibility, and water supplies for each refuge area.
5. **Staff roles and scripts.** Assign named roles for directing and reassuring people, with pre-agreed wording.

[Invacuation is the procedure many UK operators currently lack](https://martynslawsoftware.co.uk/guide/the-four-procedures). Any venue with an outdoor or semi-open space such as a beer garden, car park, or festival field needs a plan for bringing people in as well as sending them out.

### Lockdown

Lockdown means securing the premises or event to prevent people entering or leaving. Typical actions include locking doors, closing shutters, or using available barriers. A written lockdown procedure should show who secures which points and how they coordinate.

1. **Trigger authority.** Name a single role with a clear substitution chain. Decision-making must be unambiguous in the moment.
2. **Securing every entry point.** [Address every entry point, including fire exits used as smoking doors, kitchen yards, and delivery entrances](https://martynslawsoftware.co.uk/guide/the-four-procedures). Assign each point to a named role with a written sequence.
3. **Shelter-in-place instructions.** Define what people inside are told to do and how they receive that instruction.
4. **Communication during lockdown.** Specify how staff communicate with people inside while the perimeter is secured.
5. **Police interface.** Define how the responsible person hands over to police command and what information they provide.

Lockdown and invacuation are distinct procedures. [Invacuation moves people inward, and lockdown closes the perimeter](https://martynslawsoftware.co.uk/guide/the-four-procedures). The two often run together, with doors locked and people then moved to safer zones, so the written procedures must describe each step clearly. Check whether any doors release automatically on a fire alarm, because that behaviour can undermine lockdown.

### Communication

Communication means providing information, alerting people to danger quickly, and giving instructions to remain in place or move away where safe. A written communication procedure explains who speaks to which audience and through which channels.

1. **Internal staff communication.** Closed channels such as radio, staff-only PA, or a pre-agreed app, where speed matters more than tone.
2. **Public communication.** Pre-agreed scripts where clarity and calm matter more than speed. Specific, spatially grounded instructions are easier to follow under stress than vague ones.
3. **Emergency services communication.** Define who contacts police and what information they provide.
4. **Channel redundancy.** Communication systems should reach every zone, including areas away from a control room, using multiple channels such as PA, radio, mobile, and staff-led guidance.
5. **Post-incident communication.** Cover family contact, regulatory notification, and public statements.

Communication holds the other three procedures together and is often under-documented. [A documented communication procedure should specify who communicates, the channels for each audience, pre-agreed wording, and external communication after the incident](https://martynslawsoftware.co.uk/guide/the-four-procedures), which is why regulators expect to see it in writing.

## Standard Vs. Enhanced Tier: How Martyn’s Law Safety Procedures Differ

The level of documentation and testing you need depends on which tier your premises or event falls into. [Standard tier covers qualifying premises where 200–799 individuals may reasonably be expected to be present at the same time. Enhanced tier covers premises and qualifying events where 800 or more individuals may be present.](https://brodies.com/insights/health-and-safety/moving-closer-to-the-implementation-of-martyns-law) Qualifying events are always Enhanced tier regardless of the venue’s usual status.

The table below summarises how procedure requirements differ between tiers.

| Requirement | Standard Tier | Enhanced Tier |
| --- | --- | --- |
| Documented procedures for the four public protection procedures | Required, proportionate to risk | Required, proportionate to risk |
| Staff awareness and executability | Staff must be aware of procedures and able to carry them out rapidly and effectively | Same requirement, with added leadership accountability |
| Risk assessment | Not mandated in statute | Documented assessment of how procedures and measures reduce vulnerability and risk of harm, submitted to the SIA |
| Physical security measures | No specific requirement to install infrastructure | Proportionate measures for monitoring, movement control, physical safety, and security of information |
| Submission to SIA | No routine submission duty | Procedures and measures must be documented and provided to the SIA |

For a deeper look at tier definitions and scope, see [How To Comply With Martyn’s Law: A Step-by-Step Guide](https://oneplan.io/articles/martyns-law-venue-security/?utm_term=martyns-law-safety-procedures&utm_campaign=ai_growth_agent) and [Martyn’s Law For Events: What Organisers Must Do](https://oneplan.io/articles/martyns-law-public-events/?utm_term=martyns-law-safety-procedures&utm_campaign=ai_growth_agent).

## Who Is The Responsible Person Under Martyn’s Law, And What Must They Notify The SIA About?

The responsible person is the one who must meet these tier-specific obligations and interact with the SIA. [For qualifying premises, the responsible person is the individual, organisation, or company with control of the premises for the use that makes it subject to Martyn’s Law. For qualifying events, it is the individual, organisation, or company with control of the premises at which the qualifying event is taking place, for the purposes of the event.](https://www.gov.uk/government/news/martyns-law-keeping-up-the-momentum) [Responsibility is non-delegable and cannot be outsourced to a contracted service provider, though operational tasks may be delegated.](https://nortonrosefulbright.com/en-gb/knowledge/publications/235fec0e/martyns-law)

The responsible person owns the following in relation to Martyn’s Law safety procedures.

- Ensuring appropriate public protection procedures are in place so far as is reasonably practicable.
- For Enhanced tier: documenting procedures and measures and submitting them to the SIA, including an assessment of how they reduce vulnerability and risk of harm.
- For Enhanced tier where the responsible person is a company or organisation: appointing a sufficiently senior individual to ensure compliance.

Notification duties sit with the same responsible person. [Qualifying premises existing at the commencement date must notify the SIA within three months of commencement, with subsequent changes reported within 28 days. For qualifying events, in most cases the responsible person must notify the SIA within 14 days of the event date being made publicly available.](https://tlt.com/insights-and-events/insight/martyns-law-notification-guidance-the-practical-points-to-know-and-prepare-for-now) The 14-day window for events is tight. Event teams should build notification into planning and publicity processes early.

This article explains what the guidance expects. Readers should consult the Home Office statutory guidance and the SIA for definitive rulings. See also [Martyn’s Law Permit Requirements: What Venues Must Do](https://oneplan.io/articles/martyns-law-permit-requirements/?utm_term=martyns-law-safety-procedures&utm_campaign=ai_growth_agent).

## How Often Must Martyn’s Law Safety Procedures Be Tested?

Testing frequency should be risk-based and responsive to change rather than fixed by statute. [The Home Office statutory guidance sets no fixed review interval for Standard tier, but review is strongly recommended and procedures should be revisited when something material changes](https://martynslawplan.co.uk/guides/martyns-law-checklist), such as a refurbishment, a new use of the space, a change of team, or a change of responsible person. [The Home Office’s illustrative case study for a Standard-tier venue recommends reviewing procedures annually or when there is any significant change in the premises’ set-up.](https://www.gov.uk/government/news/martyns-law-guidance-published-to-help-businesses)

The schedule below shows a practical rehearsal cadence a venue operations manager could adapt. Legal minimums should always be confirmed with the Home Office statutory guidance and the SIA.

1. **Evacuation.** Test primary and secondary routes quarterly, including a full roll call and accessibility check.
2. **Invacuation.** Walk through refuge area access, capacity, and wayfinding twice a year.
3. **Lockdown.** Test every entry point, including fire exits and delivery entrances, twice a year. Verify that no doors release automatically on a fire alarm in a way that would defeat the lockdown.
4. **Communication.** Test PA, radio, and mobile channels monthly, including a redundancy check to confirm every zone is reachable.
5. **Full combined drill.** Run at least annually and after any significant change to the site or staffing structure.
6. **Post-test review.** Document what was learned and what changed within two weeks of every test. [A defensible compliance record should show why procedures are appropriate and reasonably practicable, how staff were trained, how procedures were tested, what was learned, and what changed afterward.](https://www.gov.uk/government/publications/sia-business-plan-2026-to-2027/sia-business-plan-2026-to-2027)

[Failure of procedures during a real incident is not, by itself, evidence of non-compliance. The SIA’s focus will likely be on whether procedures existed, were practised, and were reasonable for the venue](https://martynslawsoftware.co.uk/guide/the-four-procedures). A documented post-incident review that shows learning and improvement strengthens the responsible person’s position.

## What Evidence Does The SIA Expect For Martyn’s Law Compliance?

The SIA intends to take a [supportive, proportionate, and risk-based approach that includes inspections and assessments of compliance documents](https://www.gov.uk/government/news/sias-consultation-on-its-martyns-law-guidance-closes). A defensible evidence trail should combine mandatory artefacts, such as Enhanced-tier risk assessments, with practical records that show how procedures work in practice.

1. **The written procedures.** [Procedures should be specific to the venue, using building names, room names, route names, and named roles, and they should be signed by the responsible person with version history showing review dates.](https://martynslawsoftware.co.uk/guide/the-four-procedures)
2. **The risk assessment (Enhanced tier).** An assessment of how procedures and measures reduce vulnerability and risk of harm, submitted to the SIA.
3. **Training and awareness records.** [Records should show that every staff member with a role in any of the four procedures, including regular volunteers and casual staff, has read and signed the relevant instructions.](https://martynslawsoftware.co.uk/guide/the-four-procedures)
4. **Rehearsal and test records.** Timestamped where possible and covering each of the four procedures.
5. **Review logs.** Version history and review dates that demonstrate procedures are living documents, not static files.
6. **The site plan.** A to-scale plan showing where each procedure happens, including invacuation routes, lockdown points, assembly areas, and communication nodes.

[The Home Office statutory guidance notes that there is no legal requirement to prepare a document stating the procedures in place, but that demonstrating compliance may be difficult if procedures are not documented in some form](https://martynslawplan.co.uk/guides/martyns-law-checklist). For a fuller treatment of the evidence trail, see [Martyn’s Law: The Evidence Playbook For UK Venues And Events](https://oneplan.io/articles/martyns-law-compliance-guide/?utm_term=martyns-law-safety-procedures&utm_campaign=ai_growth_agent). Readers should follow the SIA and their local Safety Advisory Group for definitive requirements.

## Mapping Martyn’s Law Safety Procedures To Your Site Plan

Martyn’s Law safety procedures only work when they connect to a clear, accurate site plan. A to-scale plan documents where invacuation routes, lockdown points, assembly areas, and communication nodes sit in the real world, and it is the artefact an SIA inspector or Safety Advisory Group will ask to see.

OnePlan provides a visual, to-scale way to plan event sites and venues. It is a browser-based platform where teams drag and drop accurate, map-based objects, run intelligent crowd and traffic calculations, and collaborate on a single live plan. Built on leading GIS mapping technology powered by Esri, OnePlan has powered 200,000 events in 150 countries, from community festivals to the Paris 2024 Olympic Games.

![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**

The tools below show how OnePlan supports Martyn’s Law safety procedure documentation from mapping through to export.

- **Live, zoomable satellite or street map base layer.** Every object placed on the map stays accurately to scale at any zoom level, which gives procedures a real-world spatial context.
- **Drag-and-drop, to-scale objects.** Barriers, signage, first aid points, fencing, and more sit exactly where they will be used, so lockdown points and invacuation routes reflect how the site actually works.
- **Points of interest.** Quick, recognisable icons mark entrances, exits, assembly points, and communication nodes, which keeps plans easy to read.
- **Area and perimeter calculator.** The tool instantly returns the size of any outlined space, which helps calculate refuge area capacity and assembly point distances.
- **Crowd capacity calculator.** You can outline any standing area and instantly see its capacity based on a selectable people-per-square-metre density. Note: OnePlan supports standing crowd capacity calculations only.
- **Arrival and exit calculators.** Free tools at [OnePlan’s free arrival calculator](https://calculators.oneplan.io/arrival?utm_term=martyns-law-safety-procedures&utm_campaign=ai_growth_agent) and [OnePlan’s free exit calculator](https://calculators.oneplan.io/exit/calculator?utm_term=martyns-law-safety-procedures&utm_campaign=ai_growth_agent) model ingress queue times and exit flow rates.
- **Workforce and dot planning.** You can place medical, police, fire, security, and steward roles with shift times and routes, documenting exactly who is responsible for each lockdown point or invacuation route.
- **Bill of Quantities.** An auto-generated inventory lists everything placed on the map and exports to Excel or CSV for permit submissions and Safety Advisory Group meetings.
- **Import of existing floor plans and site plans.** You can convert existing PDFs, CAD-derived files, or drone shots to .png, import them into OnePlan, scale them onto the map, and build on top, which turns static files into reusable, buildable base maps.
- **Export to high-resolution, print-ready maps.** Exports up to A0 size support permits, Safety Advisory Group meetings, and SIA submissions.

## Martyn’s Law Safety Procedures And Your Existing Emergency Plan

Most operators already have an evacuation plan, so Martyn’s Law work usually extends existing arrangements rather than replacing them. [A fire procedure assumes the danger is the fire itself and sends everyone to the nearest safe exit and a fixed assembly point. A terrorism incident might mean the nearest exit or the assembly point is exactly where people should not be](https://martynslawplan.co.uk/guides/public-protection-procedures). Both plans need to coexist, and the differences need to be thought through for the specific building.

The additions Martyn’s Law requires are invacuation, lockdown, and a documented communication procedure, plus the tier-appropriate testing, review, and evidence trail. For most operators, the work lies in tailoring those additions to the specific site, not starting from scratch. See also [Martyn’s Law For Event Planners: A Step-By-Step Guide](https://oneplan.io/articles/martyns-law-event-planning/?utm_term=martyns-law-safety-procedures&utm_campaign=ai_growth_agent).

## When Does Martyn’s Law Come Into Force?

The Terrorism (Protection of Premises) Act 2025 received [Royal Assent on 3 April 2025](https://www.gov.uk/government/news/sia-launches-consultation-on-section-12-guidance-for-martyns-law). [The exact commencement dates will be set by the Home Office and Parliament through statutory instruments, and the law is expected to go live in spring 2027.](https://www.gov.uk/government/news/martyns-law-what-comes-next-and-how-to-get-involved) [The SIA is the designated regulator.](https://www.gov.uk/government/publications/sia-business-plan-2026-to-2027/sia-business-plan-2026-to-2027)

The SIA’s enforcement toolkit includes [compliance notices, restriction notices, and penalty notices. Maximum civil penalties for Enhanced tier non-compliance can reach £18 million or 5% of worldwide revenue, whichever is higher. Daily penalties for continued non-compliance can reach £50,000. Standard tier maximum civil penalties are up to £10,000 with daily penalties of up to £500.](https://brodies.com/insights/health-and-safety/moving-closer-to-the-implementation-of-martyns-law) [In the most serious cases, where proportionate and in the public interest, the SIA may refer those responsible for prosecution.](https://nortonrosefulbright.com/en-gb/knowledge/publications/235fec0e/martyns-law) These figures come from the SIA’s draft section 12 guidance and should be verified against final published guidance. [Martyn’s Law is not expected to come into force until 2027, and the SIA has stated clearly that it aims to make events safer rather than stop them from happening.](https://www.gov.uk/government/news/martyns-law-keeping-up-the-momentum)

## Frequently Asked Questions

### What Are The Four Martyn’s Law Safety Procedures?

The four statutory public protection procedures are evacuation, invacuation, lockdown, and communication. They describe the actions staff take when they suspect terrorism is occurring or about to occur at the premises, event, or in the immediate vicinity. Every qualifying premises and event in both tiers must have appropriate procedures for all four, tailored to the specific layout, staff, and activity.

### What Is The Difference Between Invacuation And Lockdown?

Invacuation moves people to a safer place inside the premises or event, either by bringing people in from outside or moving them between internal areas when safe. Lockdown secures the premises to prevent people entering or leaving by locking doors, closing shutters, or using available barriers. The two often run together, with doors locked and people then moved to safer internal zones, but they remain distinct procedures with different triggers and staff actions and should be clearly distinguished in the written procedure.

### Who Is The Responsible Person Under Martyn’s Law?

The responsible person is the individual, organisation, or company with control of the premises for the use that makes it subject to Martyn’s Law, or with control of the premises at which a qualifying event is taking place for the purposes of the event. For qualifying premises, this is typically the occupant with the right and ability to make decisions about the premises’ management and use, which may be a leaseholder or licence holder rather than the property owner. Responsibility is non-delegable, though operational tasks may be delegated. For Enhanced tier premises and qualifying events where the responsible person is a company or organisation, a sufficiently senior individual must be appointed to ensure compliance.

### How Often Must Martyn’s Law Safety Procedures Be Tested?

The Home Office statutory guidance sets no fixed review interval for Standard tier, but review is strongly recommended and procedures should be revisited when something material changes. As outlined in the testing section, a practical cadence is quarterly for evacuation, twice-yearly for invacuation and lockdown, monthly for communication, and annual for a combined drill. Every test should be followed by a documented post-test review within two weeks. Readers should confirm legal minimums with the Home Office statutory guidance and the SIA.

### What Evidence Does The SIA Expect For Martyn’s Law Compliance?

A defensible compliance record should show that procedures exist, why they are appropriate and reasonably practicable for the specific premises, how staff were trained and made aware of their roles, how procedures were tested or exercised, what was learned from those tests, and what changed afterward. For Enhanced tier, procedures and measures must be documented and submitted to the SIA, including an assessment of how they reduce vulnerability and risk of harm. A to-scale site plan showing where each procedure happens, including invacuation routes, lockdown points, assembly areas, and communication nodes, is a key supporting artefact.

### When Does Martyn’s Law Come Into Force?

Martyn’s Law received [Royal Assent on 3 April 2025](https://gov.uk/government/news/sia-launches-consultation-on-section-12-guidance-for-martyns-law) and is expected to come into force in spring 2027. The exact commencement date will be set by the Home Office and Parliament through statutory instruments. [The government has committed to an implementation period of at least 24 months from Royal Assent](https://gov.uk/government/news/sia-launches-consultation-on-section-12-guidance-for-martyns-law), and the SIA’s stated approach during this period is to support, advise, and guide rather than penalize. There is currently no legal obligation to comply, but operators are encouraged to begin preparing now.

## Conclusion And Next Steps

Martyn’s Law safety procedures create a documentation and rehearsal workload as well as a legal duty. The four procedures, evacuation, invacuation, lockdown, and communication, must be written, tested, and evidenced. They must also be mapped to a to-scale site plan that shows where every invacuation route, lockdown point, and communication node physically sits. The next steps are clear: review the Home Office statutory guidance and SIA guidance, confirm your tier, and start documenting your procedures on a live, to-scale plan.

The exact commencement date will be set by the Home Office and Parliament through statutory instruments. The government has committed to an implementation period of at least 24 months from Royal Assent, and the SIA's stated approach during this period is to support, advise, and guide rather than penalize. There is currently no legal obligation to comply, but operators are encouraged to begin preparing now.
