Retention Is 29%. That's Not the Bad News — It's the Sector's Biggest Opportunity

Most of us grow a children’s activity business the same way: we try to get more families in. More marketing, more ads, more classes, more venues. And there’s no better moment to question that than right now — registrations for the new season are opening, and this is exactly when providers decide how much to put on the timetable. So it’s worth stopping on one number from the most comprehensive picture of our sector yet published — because it points somewhere completely different.

The Big ICAP Report 2026 — Beyond Busy — pulls together data from 500,000+ children, 500+ activity brands and 3,892 family nominations. It’s the kind of sector benchmark this industry has never really had. And the headline finding, for me, is this: the average provider’s annual retention is 29%.

That sounds like bad news. It isn’t. It’s the biggest growth opportunity in the sector, hiding in plain sight.

Three numbers that tell one story

Read on their own, the report’s benchmarks are easy to skim past. Read together, they change the strategy:

• Occupancy sits at 56%. Nearly half of every provider’s available class capacity goes unfilled — week after week, already paid for in venue hire and staff time.
• Retention is 29%. For every ten families who join this year, roughly seven won’t be with you next year.
• More than half of new customers come through referrals. Word of mouth, not advertising, is the sector’s number-one growth engine.

And a quieter finding that ties them together: providers, on average, overestimate both their occupancy and their retention. We think the back door is shut. The data says it’s wide open.

Put those together and the picture flips. You don’t primarily have a demand problem. You have empty seats you’ve already paid for, families leaving faster than you realise, and your best marketing channel — happy families who refer — running on whatever’s left after churn takes its cut.

It’s not just one dataset — we see the same thing across Europe

It would be easy to treat one report as an outlier. But it lines up with our own numbers. Our children’s activity benchmarks, drawn from aggregated Zooza data across five European countries, land at ~54% occupancy and ~39% annual retention — a different market, a different dataset, the same story: half the seats empty, and most families gone within a year.

Our data adds one detail worth knowing: retention falls off a cliff around age six. Ages 0–5 retain at ~46%; ages 6–11 drop to ~20%. If your renewals sag when children hit school age, that’s the sector norm — not a failing unique to you.

Two independent datasets, UK and European, pointing the same way is about as clear as sector evidence gets. This isn’t a hunch. It’s where the sector actually is.

Why “more marketing” is the expensive answer

Here’s the trap. When growth stalls, the instinct is to spend on getting new families. But if you’re retaining 29% and filling 56% of your seats, every new family you win is partly just replacing one who quietly left — and landing in a business that will lose most of them again within the year. You’re pouring water into a leaky bucket and buying a bigger tap.

The report puts it more elegantly than we could. In ICAP’s own words:

“Great marketing attracts families. Exceptional experiences keep them.”

The providers seeing the strongest results, the report notes, aren’t the ones shouting loudest. They’re the ones focused on customer experience, community, retention and long-term relationships. Families themselves back this up — they say they value connection (feeling welcomed, their child growing in confidence, a sense of belonging) as much as the activity itself.

What to actually do with this

None of this means stop marketing. It means fix the economics behind the marketing first, so every new family is worth more and more of them stay. Three levers, in order of how cheap the win is:

• Fill the seats you already have — before you add more. This is the season-launch decision that matters most. A brand-new class you’ll only fill to 56% just drags your average down; filling existing capacity beats adding classes every time — no new venue, no new hire. Get this right before you finalise the autumn timetable: how to fill empty class spots.
• Keep the families you already have. Understand why they leave and build the re-enrolment moment into your term, not the week after it ends. More on that in why families leave and how to make them stay.
• Turn happy families into your marketing. With over half of growth coming from referrals, make referring effortless and reviews automatic — see social proof and referrals and collecting Google reviews.

This is exactly the ground Zooza is built for — automated re-enrolment and payment flows so families don’t leak away, loyalty for siblings and returning clients, waitlists that fill empty spots on their own, and review and referral requests that fire at the right moment. The strategy is the report’s; the plumbing is ours.
