You know your nursery inside out. But what about the air inside it?
A free indoor air quality audit gives you a clear picture of the air in your rooms, practical recommendations and confidence in where, or whether, to spend your budget.
- A clearer understanding of the air in each room
- Practical recommendations, starting with the simple ones
- Confidence in where to spend, and where not to

Proven in London classrooms
We've done this at scale in education.
As a delivery partner on the Mayor of London's School Filters Programme, we supported 218 London schools, coordinating filtration, monitoring, maintenance and support across classrooms.
We bring that experience to nurseries, focusing on what's relevant to your building rather than applying the same solution everywhere.

Sound familiar?
Three situations many nurseries recognise.
Not every nursery has a problem. But these are the places where it's worth knowing what's happening.
When the room is full
- The situation
- A room can feel stuffy when it's busy, especially in winter with windows closed.
- Why it matters
- Without measuring, it's hard to know whether ventilation is keeping up as the day goes on.
- What the audit shows
- How conditions change across the day and simple ways to improve ventilation first.
In the sleep room
- The situation
- Doors are closed and rooms are kept quiet for long periods while children sleep.
- Why it matters
- Conditions in a closed room can change without anyone noticing.
- What the audit shows
- What happens to the air during nap times and whether anything needs to change.
When traffic is close by
- The situation
- Nurseries near busy roads often wonder how much outdoor pollution gets inside.
- Why it matters
- Parents increasingly ask about it, and it's hard to answer without information.
- What the audit shows
- Whether fine particles are a concern indoors and which rooms to prioritise, if any.
The free audit
What the audit includes, and what you receive afterwards.
Illustrative example of how CO₂ can change across a nursery day. Your audit shows your real readings, room by room.
During the audit
- A visit from our team at a time that suits your nursery
- Readings in the rooms that matter most: playrooms, the sleep room and rooms facing the road
- CO₂ (a sign of how well a room is ventilated), fine particles (PM2.5), temperature and humidity
- A look at how rooms are ventilated and used through the day
Afterwards, you receive
- A short, plain-English summary of what we found, room by room
- Practical recommendations, starting with low or no-cost changes
- Costed options only if something is worth investing in, including running and maintenance costs
- Information you can share with your team and with parents
The audit is free for nurseries within the M25, with no obligation to buy anything. Outside the M25? We'll start with a free introductory call.

Hi, I'm Tommy.
I'd rather understand your nursery and what matters to you before talking about products. If there's a simple fix, I'll tell you. If there's no reason to invest yet, I'll tell you that too.
