Ratios Are Not Optional

If your holiday camp is registered with Ofsted (and if you care for children under 8 for more than two hours a day, registration is compulsory), you are legally required to maintain specific staff-to-child ratios at all times. Not most of the time. Not on average across the day. At all times, including during transitions, lunch breaks, and the chaotic fifteen minutes around drop-off and collection.

Getting ratios wrong is one of the fastest ways to receive an inadequate Ofsted rating, and it is one of the most common compliance failures inspectors find at holiday camps. The good news is that the rules are clear. The challenge is maintaining compliance when your daily numbers fluctuate, staff call in sick, and you are running multiple activities across different venues simultaneously.

Ofsted Ratio Requirements by Age Group

The ratios for holiday camps and out-of-school provision in England are set out in the Early Years Foundation Stage (EYFS) framework and the Childcare Register requirements. The key ratios are:

Under 2 Years

One adult to every three children (1:3). Most holiday camps do not accept children this young, but if you offer a baby or toddler group alongside your main camp, this ratio applies and is non-negotiable.

Ages 2 to 3

One adult to every four children (1:4). Again, this is unusual for multi-sport camps but relevant if you accept very young siblings alongside older children.

Ages 3 to 7 (EYFS and Early Compulsory School Age)

One adult to every eight children (1:8). This is the ratio that applies to most of your younger groups. At least one member of staff in each group must hold a relevant Level 3 childcare qualification (or equivalent). If no Level 3 qualified member of staff is present, the ratio tightens to 1:4.

Ages 8 and Over (Voluntary Part of the Childcare Register)

Ofsted does not prescribe a specific ratio for children aged 8 and over, but you must demonstrate that your staffing is sufficient for the activities being undertaken and the needs of the children. In practice, most insurers and governing bodies expect a ratio of no more than 1:10 or 1:12 for general activities, and tighter ratios for higher-risk sports.

Mixed-Age Groups

If your groups contain children of different ages, the ratio for the youngest child in the group applies. A group with twelve children aged 6 to 10 must maintain the 1:8 ratio because of the six-year-olds present. This is a common trip-up for camps that group by ability rather than age.

First Aider Requirements

Ofsted requires that at least one person with a current paediatric first aid (PFA) certificate is on the premises at all times when children are present. For EYFS-age children (under 5), at least one person with PFA must be on each outing and in each group.

What Counts as a Valid Certificate

The PFA certificate must be a 12-hour course (usually delivered over two days) and must be renewed every three years. A standard first aid at work certificate is not sufficient for children under 5, although it is acceptable for older children on the voluntary register. Emergency PFA (a shorter 6-hour course) is accepted as a minimum in some circumstances but is not best practice.

For a multi-sport camp running multiple groups across different venues, you need enough qualified first aiders so that every group has access to one. If Group A is on the pitch, Group B is in the hall, and Group C is at the swimming pool, you need a first aider with each group, not just one person somewhere on site.

Activity-Specific Ratios

Certain activities carry higher risk and require tighter ratios than the general Ofsted minimums. These are typically set by the relevant governing body or your insurance provider.

Swimming: Swim England recommends a maximum of 20 swimmers per qualified lifeguard in a pool, with additional instructors at ratios of 1:6 for non-swimmers and 1:12 for competent swimmers. If you are using an external pool, the pool operator will enforce their own ratios.
Archery: ArcheryGB recommends 1:6 for beginners and 1:12 for experienced archers, with a qualified instructor present at all times.
Climbing and bouldering: The Association of British Climbing Walls recommends 1:4 for roped climbing with beginners and 1:6 for bouldering.
Water sports (kayaking, paddleboarding): British Canoeing recommends 1:6 on the water, with a qualified coach and a safety boat or bank support.
Trampolining: British Gymnastics recommends 1:1 supervision during early learning stages and never more than one person on a trampoline at a time.

Your risk assessment for each activity should specify the ratio required, and your schedule should be staffed accordingly. If your archery session has 18 children, you need three qualified instructors, not two plus a general assistant.

Break Cover and Ratio Maintenance

Staff need breaks. The Working Time Regulations 1998 entitle workers to a 20-minute uninterrupted break during any shift of six hours or more. But when a staff member goes on break, the ratio must still be maintained.

Practical Solutions

Floating cover staff: Employ one or two additional staff members whose role is to cover breaks, toilet runs, and unexpected absences. They rotate between groups throughout the day, releasing each group leader for their break in turn.
Staggered breaks: Schedule breaks so that no more than one person from each group is on break at any time. Publish the break rota at the start of each day so everyone knows when they are covered.
Lunch supervision: Lunch is often when ratios slip. Children are gathered in one space, some staff are eating, and the assumption is that fewer staff are needed because it is not an activity session. This is wrong. The ratio must be maintained during lunch, and lunch is when many behavioural issues and accidents occur.

Sickness and No-Shows

Have a clear plan for staff sickness. If a member of staff calls in sick at 07:00 and camp starts at 08:30, you need to know immediately whether you can still meet ratios. Maintain a list of trained relief staff who can be called in at short notice. If you cannot meet ratios, you may need to reduce the number of children you accept that day, which means contacting parents early.

Ratios are not just about compliance. They are about safety. Every child in your care deserves adequate supervision, and every staff member deserves manageable group sizes. Building headroom into your staffing plan is not an unnecessary cost; it is the foundation of a safe camp.

Key Takeaways

Know the Ofsted ratios for every age group in your camp and apply the ratio for the youngest child in any mixed-age group.
Ensure every group has access to a qualified paediatric first aider, not just one person on the premises.
Check governing body and insurer requirements for activity-specific ratios, which are often tighter than general Ofsted minimums.
Plan break cover with floating staff and staggered rotas so ratios are maintained during breaks, lunch, and transitions.
Maintain a list of trained relief staff who can be called in at short notice to cover sickness without breaching ratios.
