A village fete, a corporate family day, a charity 10k, a three-day music festival: every event brings people together in a space that was never designed for them, often outdoors and often on a temporary site. Yet event first aid requirements are some of the most misunderstood in UK health and safety. Organisers often assume that because attendees are not employees, first aid for the public is optional.
That assumption does not hold up. This guide explains what the law requires, how the industry's Purple Guide shapes planning, what changed for event medical providers in September 2026, and the kit you should have on site.
What UK law says about event first aid requirements
Your duty to staff, stewards and crew
The Health and Safety (First-Aid) Regulations 1981 require every employer to provide adequate and appropriate equipment, facilities and personnel so that employees receive immediate attention if they are injured or taken ill at work. At an event, that covers your stewards, bar staff, site crew and anyone else you employ. Contractors such as caterers or staging companies carry the same duty for their own workers.
This duty covers build and breakdown too, which often carry the highest injury risk.
Is first aid for the public a legal requirement at events?
The 1981 Regulations do not strictly require you to provide first aid for members of the public. However, HSE strongly recommends including the public in your first aid needs assessment, and its first aid guidance states plainly that at events such as concerts, it is the event organiser's responsibility to ensure the availability of medical, ambulance and first aid assistance as appropriate for all those involved.
Other legal duties also apply:
- Section 3 of the Health and Safety at Work etc. Act 1974 requires you to conduct your undertaking so that people who are not your employees are not exposed to risks to their health and safety, so far as is reasonably practicable.
- Regulation 3 of the Management of Health and Safety at Work Regulations 1999 requires a risk assessment covering everyone affected by your activities, not just staff.
- Licensing and land use conditions frequently set first aid provision as a condition of a premises licence, event licence or use of council land.
Larger events may also go before a local authority Safety Advisory Group (SAG), where the ambulance service can comment on your medical plan. There is no single "events first aid law", but together these duties make it very hard to justify no provision for attendees.
Planning event first aid cover with the Purple Guide
HSE points organisers towards the Events Industry Forum's Purple Guide, which is the recognised UK reference for event health, safety and welfare. At its heart is the medical needs assessment: a documented, event-specific assessment of the first aid and medical cover you need.
The current guidance has dropped the old table-based "score sheet". It still groups events into five tiers, from Tier 1 (the smallest and simplest) to Tier 5 (mass gatherings and complex, higher-risk events), but the tier follows from your assessment rather than your ticket numbers alone. Factors to consider include:
- audience size and profile, such as families, young people or older visitors
- whether alcohol is served
- the nature of the activity, from a seated talk to an obstacle race
- indoor or outdoor setting, season and expected weather
- duration, and whether there is overnight camping
- distance to the nearest A&E and access for ambulances
- incident data from previous years
Even at Tier 1, where a contracted medical team may not be needed, the Purple Guide expects organisers to consider a suitable first aid kit, someone able to use it, the location of the nearest defibrillator, and how people will summon emergency help.
How many first aiders do I need at an event?
There is no fixed legal number: it should come from your medical needs assessment. As a practical benchmark, two first aiders is widely treated as the minimum for any event, and established providers such as St John Ambulance will not send fewer than two. St John Ambulance also suggests a rough starting estimate of two first aiders per 1,000 people, adjusted for the risk factors above. Treat these as planning benchmarks, not statutory minimums, and record the reasoning behind your final figure.
What changed in 2026: CQC regulation of event medical providers
Following recommendations from the Manchester Arena Inquiry, the Health and Social Care Act 2008 (Regulated Activities) (Amendment) Regulations 2026 remove the exemptions that kept clinical care at sporting and cultural events outside the Care Quality Commission's remit in England. Providers delivering "treatment of disease, disorder or injury" at events, such as paramedics, nurses and doctors working in a professional capacity, have been able to apply for CQC registration since 7 September 2026. From 6 December 2027, providing that care without registration becomes an offence.
For most organisers, the key point is that first aid itself remains outside CQC regulation, so your trained first aiders and kits are unaffected. The change matters when you book clinical cover: ask the provider whether they are registered, or have applied, before signing. The Department of Health and Social Care is also developing a non-statutory Event Healthcare Standard.
First aid kit for events: equipment checklist
Start with a BS 8599-1 compliant workplace kit sized to your event, then build out for the realities of a temporary site:
- Portable, weatherproof kits. Grab bags and rucksack kits for roving first aiders; sturdier cases for fixed first aid points. Outdoor sites expose kits to rain, mud and heat.
- Enough kits, in the right places. One at every first aid point and one with each roving team, so help can reach any part of the site quickly.
- Burns provision. Food traders, barbecues, generators and pyrotechnics all create burn risks that a standard kit is not stocked to handle.
- Bleed control kits. Worth considering where there is plant, vehicle movement, fairground rides or heavy stage build.
- Foil blankets for outdoor events in cooler months, and eyewash where dust or chemicals are present during build.
- A defibrillator. An AED is not a legal requirement at events, but the British Heart Foundation reports more than 40,000 out-of-hospital cardiac arrests in the UK each year, with fewer than one in ten people surviving. Large crowds, heat and physical exertion all add risk. If you own or hire an AED, register it on The Circuit for the duration of the event so the ambulance service knows where it is.
- Clear identification. First aid point signage using the BS EN ISO 7010 green cross symbol, marked on the site map, and high-visibility tabards so first aiders are easy to find in a crowd.
Setting up a first aid point
Aim for a treatment area that is clean, well lit, dry, private and sheltered; for a small event, a gazebo with sides may be enough. Give it vehicle access for an ambulance, signpost it clearly, and make sure every steward knows where it is and how to call a first aider by radio.
Recording incidents and RIDDOR at events
Keep an accident book for staff injuries, and make sure your first aid provider completes a treatment record for every attendee they see. Under RIDDOR, you must report to HSE any case where a member of the public is injured as a result of a work-related accident, such as a trip over a trailing cable or the collapse of a temporary structure, and is taken directly from the scene to hospital for treatment. Precautionary hospital visits where no injury is apparent are not reportable, and HSE's own examples confirm that someone taken to hospital after simply fainting does not need reporting.
Practical takeaways
- Complete a documented medical needs assessment covering build, the live event and breakdown.
- Include the public, as HSE strongly recommends, and check your licence or land use conditions.
- Plan for at least two trained first aiders, scaling up by risk rather than headcount alone.
- Confirm any clinical provider's CQC registration status ahead of December 2027.
- Give every first aid point and roving team a weatherproof, BS 8599-1 compliant kit, adding burns, bleed control and AED provision where your risks call for it.
- Mark first aid points clearly, brief stewards, and keep incident records ready for RIDDOR.
