Event Safety Cover: Medical, Security & Stewarding

A practical starting point for organisers planning medical, security and stewarding cover. It is not a substitute for your own risk assessment or Event Management Plan — just a friendly overview of the things that shape good cover, and the bits that often catch people out.

Start with the bigger picture

Cover for a UK event is shaped by The Purple Guide, your licence conditions and your local Safety Advisory Group. Numbers on a page only get you so far — what matters is whether your provision matches the event you are actually running, on the day, in that venue, with that crowd. Medical, security and stewarding are best scoped together so they complement each other rather than overlap or leave gaps.

Medical cover

The size and shape of medical cover is usually driven by three things more than anything else:

  • Crowd. Peak concurrent attendance — not total ticket sales — and who is in it (families, older audiences, alcohol, camping).
  • Activity. Music, sport, motorsport, water, pyrotechnics, heritage re-enactment — each carries its own pattern of injuries.
  • Environment. Indoor or outdoor, terrain, weather exposure, and how long an NHS crew would realistically take to reach you.

Security cover

Security is not just "doors and bags". A workable plan tends to think about each of these together:

  • SIA-licensed roles. Door supervisors, search teams and close protection where the role legally requires a licence.
  • Perimeter and access. Ingress and egress flow, accreditation, back-of-house separation, vehicle control.
  • Threat picture. What is realistic for this event — alcohol, protest, lone-actor concern, cash handling, VIPs — and how that scales staffing.
  • Counter-terrorism awareness. Proportionate to scale, but worth touching even at smaller events (HVM, ACT, briefings).

Stewarding

Stewards are not security and the distinction matters — for licensing, for insurance and for what you can lawfully ask them to do. A good steward plan usually covers:

  • Crowd management. Flow, density, queue dynamics, pinch points, signage.
  • Customer-facing roles. Welcome, information, accessibility support, lost children, lost property.
  • Safety roles. Fire stewards, evacuation marshals, pit and barrier teams where relevant.
  • Training and briefing. Site induction, radio discipline, escalation routes to security and medical.

A few legal and guidance baselines

Organisers often ask "what is the minimum cover we need for a festival?" The honest answer is: there is rarely a fixed statutory number.

What the licensing authority and Safety Advisory Group (where there is one) expect is that your provision matches your risk assessment and your Event Management Plan (EMP). Not every event has a SAG, so your EMP needs to be thorough — we have seen EMPs ranging from a few dozen pages to nearly a hundred, depending on the size and complexity of the event.

This is a guide to start the conversation, not a science. Exact numbers always come from your specific risk assessment, EMP and any SAG or licensing officer involved.

  • Bar and alcohol areas. A venue or event that sells alcohol usually has licensing conditions that require SIA-licensed door supervision in specific ratios. The exact requirement comes from your licensing officer and SAG, but a common starting point in busy bar or late-night areas is around one SIA door supervisor per 100 patrons. This is a security-to-patron ratio, not a way to replace medical cover or fire safety marshals — those are separate provisions and must be staffed in their own right.
  • Crowd-to-medic thinking. Industry guidance (including the Purple Guide) discusses medical cover in terms of peak crowd density, activity type and ambulance handover time, not a flat headcount ratio. A low-risk seated event may need very different cover to a mosh pit or motorsport arena with the same ticket sales.
  • Stewards vs SIA roles. Only SIA-licensed staff can do certain security work by law. Asking a steward to act as a door supervisor or to use force can breach licensing conditions and invalidate insurance.
  • No dual roles on the day. One person cannot act as security, medic and fire safety marshal all at once. SIA, medical and fire safety are separate functions with separate training, insurance and lines of authority. Dual hatting is frowned upon by insurers because it creates gaps at the exact moments cover is needed.

The best use of these numbers is as a sense-check, not a final specification. If your event is anything more than a small, low-risk gathering, it is worth running the numbers past your SAG or licensing officer and a provider who can show their working.

Things that catch people out

  • Ticket totals being used in place of peak concurrent attendance
  • Dual-role staffing where one person is expected to cover security, medical and fire safety roles
  • Stewards being asked to do work that legally requires SIA cover
  • Welfare and mental health being lumped in with clinical cover
  • Late engagement with the SAG, licensing authority and NHS ambulance trust
  • Providers who cannot show their working, insurance or governance
  • Multi-day events scoped as if they were a single day

What "good" looks like in a brief

A useful first conversation usually starts with a one-pager: dates, venue, peak crowd, audience profile, activities, alcohol policy, on-site hours and anything unusual. From that, a decent provider can sketch medical, security and stewarding together and explain the trade-offs in plain English — before any quote.

Want us to walk you through it?

We are a working provider, not a free consultancy — but a short, friendly chat is usually possible. Tell us roughly what you are planning and, where we can, we will point you in the right direction on what medical, security and stewarding tend to look like for that kind of event and what your SAG is likely to expect.

If you have engaged us for an event, you naturally get more of our time as a value add — joining SAG meetings where useful, sharing templates and additional resources, and being on the end of the phone in the run-up.
