Why These Events Are a Category of Their Own
When most people picture event security, they picture a festival fence line, a stadium turnstile, or a concert venue with a clear perimeter separating the event from the outside world. Security in those settings, while demanding, operates within a controlled framework: you know who is coming, roughly how many will attend, and where they will enter and exit.
The Open-Access Challenge
Public parades and community markets are fundamentally different. They are open-access events by design, woven into the fabric of everyday public life in towns and cities across the United Kingdom. A Christmas market trading across a town centre, a summer carnival processing through a city high street, a cultural festival spilling across a public park these events are not defined by gates or fences.
Anyone can arrive at any time, linger as long as they choose, and leave by any number of routes. That openness is the very thing that makes them vital community occasions. It is also what makes securing them one of the most operationally complex tasks in the event security sector.
Rethinking the Standard Approach
Understanding public and community event security properly means accepting at the outset that the conventional event security playbook does not apply. Almost every tool, structure, and assumption used at a ticketed venue must be rethought from scratch. Organisers and security professionals working in this space are not simply applying a known formula to a new setting. They are building their approach from the ground up, every time, for every event site.
The Core Challenge: No Perimeter, No Capacity Control
When the Perimeter Disappears
At a ticketed event, the perimeter is the foundation of the security model. Everything flows from it: access control, crowd counting, exclusion of prohibited items, emergency lockdown, and evacuation. Remove the perimeter, and the entire architecture of conventional event security collapses.
For a street market or a parade, there is no perimeter in the traditional sense. Crowd numbers cannot be accurately capped, because there is no mechanism to stop members of the public entering. Numbers fluctuate throughout the day as passers-by join spontaneously, particularly in busy town centres.
A traders' market intended to attract 500 people over a morning can draw three times that number on a sunny Saturday if a nearby shopping street redirects foot traffic. A parade that assembles with 2,000 participants can attract tens of thousands of spectators lining the route, with no advance booking, no ticket, and no formal registration.
Translating Uncertainty Into a Safety Plan
This creates a distinct planning challenge. As the HSE's event safety guidance and the widely used Purple Guide both emphasise, event organisers must translate what is known about a site, a crowd, and a route into an appropriate safety plan, but for open-access community events, even the foundational data is much harder to gather with certainty. Calculating a safe capacity for a venue with no walls requires specific expertise and can only be performed by a competent person with experience of the site and the likely crowd behaviour.
The Moving Venue Problem
For a parade specifically, the event is not just open, it is in motion. The route itself becomes the venue, and the risk profile changes continuously as the procession moves from street to street. The Metropolitan Police's published guidance to public event organisers notes that marches present a moving venue that is far more unpredictable than fixed-site events, making early, accurate predictions of participant numbers and spectator volumes essential so that traffic management, emergency service access, and stewarding can be scaled appropriately.
What Council and Police Guidance Actually Requires
Starting With Your Local Authority
Across the UK, local councils and police forces have developed detailed guidance and requirements specifically for public and community events. The starting point in almost every case is the same: contact your local council as early as possible. Many councils publish their own council event security type guide or event organiser handbook, and engaging with these resources early in the planning process is strongly encouraged.
The Role of the Safety Advisory Group
Most councils operate a Safety Advisory Group, commonly referred to as an SAG. This is a multi-agency forum that brings together representatives from the local authority, police, ambulance service, fire and rescue service, and other relevant bodies to provide coordinated advice on public safety planning for events. The safety advisory group is consulted on everything from town centre carnivals to charity fun runs, and for community markets of any significant scale, engagement with the SAG is expected before an event takes place.
Importantly, as the Council's event safety guide makes clear, a SAG is not a permission-granting body. It cannot approve or prohibit an event from taking place. What it does is bring together the right expertise at the right stage of planning, and ensure that no single agency's concerns are overlooked. Failure to satisfy the local SAG can, however, have real consequences: it may affect public liability insurance arrangements, and individual member agencies retain the right to take independent regulatory action under their own legal powers.
The Event Management Plan
What the SAG typically expects an organiser to produce for a community market or parade includes an Event Management Plan, commonly referred to as an EMP. This is a comprehensive document setting out crowd management arrangements, security and stewarding plans, traffic management proposals, emergency access routes, first aid provision, and communications strategies. Many councils, publish EMP templates specifically to help guide community event organisers through what is required.
Licensing and Road Closures
Road closures, almost always necessary for both parades and pedestrianised markets, require a separate application to the relevant highways authority and must be applied for at least three months before the event. Where a parade includes a route along a public highway, the highways authority must approve all signage and traffic management measures, and a competent person must be responsible for installing and supervising them.
For any market operating on council land, a street trading licence is required. Under the London Local Authorities Act 1990 and the Local Government (Miscellaneous Provisions) Act 1982, street trading is a licensable activity, and councils issue licences that come with specific conditions around safety, hygiene, access, and increasingly, security planning.
SIA, Stewards, and Who Does What
Understanding the Legal Distinction
A common source of confusion in community event security is the distinction between SIA-licensed security personnel and event stewards. Getting this wrong is not just a compliance issue, it can create genuine gaps in public safety.
SIA-licensed Door Supervisors hold a qualification regulated by the Security Industry Authority and are authorised to carry out a range of licensable activities, including searching persons and property, controlling access, and dealing with ejections. Stewards and marshals do not hold this authority. As guidance from District Councils, Avon and Police makes clear, stewards cannot search bags or persons unless they hold an SIA licence.
Untrained, unlicensed stewards performing the role of SIA-licensed door supervisors is a recognised problem in community events, and it is the event organiser's responsibility to ensure the distinction is maintained and that the right personnel are deployed for the right tasks.
Briefing, Identification, and Ratios
For large public events, SIA-licensed operatives are required. For many smaller community events such as village fêtes, local markets, and small processions, volunteers may serve as stewards, but they must be properly briefed, clearly identified by high-visibility tabard or vest, and informed about their specific responsibilities. At a minimum, stewards must know the site layout, the location of emergency exits and first aid points, the communication chain for reporting incidents, and their personal role in the event of an evacuation.
The ratio of stewards to attendees matters considerably. For events over 1,500 participants, the Guide to Safety at Sports Grounds recommends a minimum ratio of one steward per 250 attendees for mobile stewarding roles, increasing to one per 100 or higher where the risk assessment identifies elevated risk. Avon and Somerset Police recommend one steward or marshal per 100 people as a baseline for general public events, with higher ratios where the audience includes children, vulnerable people, or alcohol is present.
Stewards at Parades: A Different Kind of Vigilance
For parades, stewards must monitor the crowd and not watch the event. This distinction, emphasised in guidance to event organisers, is fundamental. Stewards must report anything likely to lead to a breach of the peace or a criminal offence directly to police. Critically, if police instructions conflict with those of the event organiser, stewards must follow police directions. Communication between stewards across a parade route is typically maintained by radio, and GMP explicitly warns against reliance on mobile phones, which may become unreliable in an emergency when networks become overloaded.
Martyn's Law and the Changing Legal Landscape
What the Act Means in Practice
The Terrorism (Protection of Premises) Act 2025, known as Martyn's Law after Martyn Hett, one of the 22 people killed in the 2017 Manchester Arena attack, received Royal Assent in April 2025 and will come into full effect in April 2027. Its implications for community events are significant and, in some respects, little understood outside specialist security circles.
The Tiered Duty System
The Act creates a tiered duty system. The standard tier applies where between 200 and 799 people can be expected; the enhanced tier applies at 800 or more. For a busy Saturday market or a well-attended parade, these thresholds are easily crossed.
The enhanced duty also explicitly applies to temporary outdoor events, including those taking place at locations that would not ordinarily qualify as fixed premises, where public access is expected and attendance exceeds 800. A Christmas market in a town square or a summer carnival route falls squarely within the scope of this provision.
New Obligations for Organisers
Under the standard duty, organisers must carry out a terrorism evaluation and ensure staff are trained in appropriate responses to a potential attack. Under the enhanced duty, additional documented measures are required, including evacuation and lockdown procedures, terrorism vulnerability assessments, and formal compliance documentation.
The Security Industry Authority is the designated regulator with powers to inspect, issue enforcement notices, and levy substantial financial penalties for non-compliance.
Counter-Terrorism Training Is No Longer Optional
The practical implication for community event organisers is that counter-terrorism awareness is no longer optional background knowledge. It is an increasingly formalised legal obligation. The National Counter Terrorism Security Office's ACT e-learning programme and the ProtectUK platform are both recommended by councils and police services across the UK.
Free training resources for event staff and volunteers are all available online. Many council guides and police event planning pages now specifically state that all stewards and marshals should complete ACT training before working at an event.

Hostile Vehicle Mitigation: The Open-Air Risk
A Threat Specific to Open Events
Among the most distinctive and challenging security requirements for parades and outdoor markets is hostile vehicle mitigation, known in the sector as HVM. Following a series of vehicle-as-weapon attacks in Europe and the UK, the threat posed by vehicles being deliberately or accidentally driven into pedestrianised public spaces is now taken extremely seriously by security planners, local authorities, and the National Protective Security Authority.
For a parade or community market, this threat is particularly acute. The event space is defined precisely by pedestrians occupying road space ordinarily used by vehicles. Road closures reduce but cannot entirely eliminate the risk; adjacent roads remain live, and the boundary between the event and traffic can be porous.
Deploying Barriers Without Creating New Hazards
Temporary HVM solutions, including rapidly deployable barriers, surface-mounted bollards, and water-filled barrier systems that require no groundworks, are now routinely deployed at community events, particularly in town centres and city streets. The NPSA's guidance, drawn from extensive research at UK venues, makes clear that HVM measures must be integrated carefully into crowd management planning.
Poor barrier placement can create bottlenecks and dangerous increases in crowd density, introducing new hazards rather than reducing them. For parades especially, HVM infrastructure along the route must be positioned in a way that maintains clear emergency access corridors and does not impede the orderly movement of large numbers of people.
The Setup Phase: A Risk Period Unique to Markets
Before the Public Arrives
One aspect of community market security that receives comparatively little attention is the vulnerability of the setup and breakdown phases. Before a market opens to the public, the event site is a working environment.
Traders arrive in vehicles, gas canisters and electrical equipment are brought onto the site, temporary structures are assembled, and access must be managed for dozens of independent contractors simultaneously.
Managing Vehicles in a Future Pedestrian Zone
During this period, vehicle movements through what will later be pedestrianised space are both necessary and hazardous. Access to the site must be controlled, and a clear cut-off time for vehicle movements, after which no vehicles may enter the market area, must be established, communicated to all traders in advance, and enforced.
Council EMP templates include specific provisions for this phase, requiring that rules around vehicle exclusion after a specified time are set out clearly in the event management plan.
Trader Compliance and Documentation
Food traders at markets introduce additional regulatory layers: they must hold appropriate food hygiene qualifications, register as food businesses, and provide evidence of public liability insurance and their own risk assessments. All of this documentation passes through the event organiser, who bears overall responsibility for verifying compliance before the market opens.
Security That Supports, Rather Than Suppresses
Visibility Without Intimidation
Perhaps the most important characteristic of good community event security is that it should be largely invisible to the people attending. Markets and parades exist to celebrate community life, to bring people together in public space in a spirit of shared enjoyment. Security measures that feel heavy-handed, intrusive, or unwelcoming work against this purpose and can create an atmosphere of unease that undermines the welfare of everyone present.
The best-planned community events achieve their security objectives through good site design, clear signage, intelligently positioned stewarding, and well-rehearsed emergency procedures that run quietly in the background while people go about their day. Barrier systems that double as site definition, stewards who are known in the community and whose primary visible role is helping people find their way these are the hallmarks of security that support a safe and successful event without overshadowing it.
Preparation Is Everything
Achieving that apparent simplicity requires intensive preparation long before the day of the event. It requires early engagement with the local council and safety advisory group, thorough risk assessment by competent people with the right experience, proper licensing, correctly qualified and briefed security staff, and a genuine understanding of the specific characteristics of the site and the community it serves.
Organising a public parade or community market safely is a serious undertaking, and the standards expected of event organisers across the UK continue to rise. As Martyn's Law takes effect and the framework for public event safety continues to develop, that preparation is no longer simply good practice. For many events, it is the law.
