The short answer: the law sets no fixed number of first aiders for a children's play venue. The Health and Safety (First-Aid) Regulations 1981 require you to provide whatever is “adequate and appropriate in the circumstances”, and a needs assessment you carry out decides what that means for your venue. For a typical soft play centre the defensible working answer is at least one first aider with paediatric training on the floor at all times the venue is open, scaling up for capacity days. Here's how to get from the legal wording to your own number.
The legal duty has a twist most operators miss
The First-Aid Regulations 1981 technically cover your employees only. Read literally, the law obliges you to provide first aid for your staff of twelve, and says nothing about the four hundred children in the building. Nobody should run a venue on the literal reading. The HSE's own guidance at hse.gov.uk/firstaid strongly recommends including non-employees in your provision, your duty of care to visitors does the rest, and your insurer assumes it. The practical consequence: your needs assessment must be sized for the public in the building, not the payroll.
What the HSE benchmarks suggest, and why they're only a floor
For workplaces, HSE guidance sketches minimums by risk level and headcount. A low-hazard office under 25 people can get by with an “appointed person” who manages the kit and calls 999 but needn't be trained in first aid. Bigger or higher-risk workplaces step up to trained first aiders holding one of two qualifications: EFAW (Emergency First Aid at Work, a one-day course) or the fuller three-day FAW (First Aid at Work).
Apply those employee-counting benchmarks to a play venue and you'd conclude one appointed person covers it, which shows exactly why they're a floor and not an answer. Your risk profile isn't your staff count. It's hundreds of children doing an activity that generates bumps, falls and the occasional fracture, which our RIDDOR guide covers from the reporting end. The needs assessment factors that actually size your provision:
- Peak occupancy, not average. The provision that works on a Tuesday morning fails on the first wet Saturday of half term.
- The building's geography. If the first aider is on the café till and the casualty is on level three of the frame, minutes disappear. Big or multi-room venues need cover per area, not per building.
- Shifts and absence. “We have four trained first aiders” means nothing on the Sunday all four are off. The rota, not the roster, is the test. Cover for holidays and sickness is explicitly part of the assessment.
- What actually happens. Your accident book is a first aid demand forecast. If Q3 produced thirty incidents needing treatment, you know your load.
- Ambulance response reality. A rural venue twenty minutes from the nearest ambulance station needs more capability on site than one across the road from a hospital.
Why paediatric training is the one that matters
Standard workplace first aid courses are built around adult casualties. Children are not small adults: choking response differs, CPR technique and ratios differ, and the things children actually do (swallow a marble, wedge a bead up a nose, spike a fever mid-party) barely feature in an adult syllabus. A 12-hour paediatric first aid course covers exactly this ground. It's a hard requirement in registered early years settings, and for a venue whose casualties are overwhelmingly under ten, running a first aid rota without paediatric-trained cover is a choice you'd struggle to defend after the event.
Our working recommendation, and the one we'd put in a needs assessment: every shift's designated first aider holds paediatric first aid, with EFAW or FAW as the base layer across the wider team so a second pair of trained hands is never far. Party hosts are strong candidates for the paediatric course; they're standing next to the highest-density room in the building.
Kits, locations, and the fifty-second rule
Stock kits against BS 8599-1, the British Standard for workplace first aid kits, and size them for footfall rather than staff count. Then think in seconds rather than compliance: from any point in the venue, how long to reach a kit? A single kit behind reception fails the frame, the party rooms and the toilets simultaneously. Most venues land on a main kit plus satellites (frame entrance, party corridor, kitchen with its burns dressings), each with a named restocker and a monthly stock check on the checklist. Add the two items parents will beg you for: a working thermometer and a freezer full of cold packs.
Paperwork that follows the incident
Every treatment gets an accident book entry, and the serious ones flow into RIDDOR reporting where the criteria are met. Two records to keep straight on the personnel side: certificates and refreshers. FAW and EFAW certificates run for three years and then require requalification, the HSE strongly recommends annual refresher practice in between, and paediatric certificates carry their own renewal cycle. A venue with six first aiders and no expiry tracking will, with mathematical certainty, one day discover it has zero current first aiders and a rota that assumed otherwise.
Write the needs assessment in an hour
The first aid needs assessment sounds like a project and is actually a page. Sit down with your accident book, your rota and a floor plan, and answer in writing:
- What are our realistic casualty scenarios? (Falls in the frame, choking in the café, burns in the kitchen, an adult collapse. Your accident book already ranks these by frequency.)
- What's our peak occupancy, and on how many days a year do we hit it?
- How many trained people do we need on the floor at peak, where do they need to be, and what training does each hold?
- What does the rota look like on our thinnest realistic day, and does the answer to question three survive it?
- Where are the kits, what's in them, and who restocks them?
- Who reviews this, and when? (Annually, plus after any incident that stretched the provision.)
Date it, sign it, and file it with your risk assessment. When something serious happens, this page is the difference between “we'd thought about this” and improvising an answer in front of someone taking notes.
Quick answers
Is one first aider enough for a 300-capacity venue? On the floor at once, probably not, and your needs assessment will say so once peak occupancy and building geography are in it. One per open zone or floor level is a saner starting point at capacity.
Can the appointed person just be whoever's on shift? The appointed-person role is a named minimum for tiny low-risk workplaces, not a play venue's answer. If you use the concept at all, use it as the kit-and-call-999 backstop behind trained cover, never instead of it.
Do party hosts need first aid training? No law says so by job title. But they're supervising the densest concentration of children in your building, so they're where training buys the most. At minimum they must know who the shift's first aider is and how to summon them fast.
Does the café change anything? Yes: burns risk for staff, choking and allergic reactions for customers. Kitchen-adjacent burns dressings and an anaphylaxis-aware first aider stop being optional the day you serve food.
Where SafePlay fits
The failure mode here is never the training. It's the tracking. SafePlay's Staff Compliance holds every team member's first aid qualification with its expiry date, reminders fire before certificates lapse rather than after, kit checks live in Daily Checks with a name against every restock, and your needs assessment sits versioned in the Document Vault next to the risk assessment it belongs with. The question “who on today's rota is first aid current?” should take four seconds, because one day it will be asked at speed.
