Healthier classroom air for UK schools
SchoolAirQuality.uk helps schools, academy trusts, nurseries, colleges and local authorities measure, understand and improve classroom air quality. From CO₂ and ventilation assessments to continuous environmental monitoring, our work supports healthier learning environments and stronger pupil and staff wellbeing.

№ 01 — Why it matters
Air quality shapes how pupils learn, concentrate and feel at school.
Pupils and staff spend the majority of their working day inside classrooms. Indoor air quality, ventilation rates and thermal conditions in those rooms directly affect comfort, concentration and overall wellbeing — and have become a recognised priority in UK school operations.
We help schools translate this into something practical: where the classrooms with the most pressure on ventilation are, which spaces show elevated CO₂ or particulate levels during the school day, and where simple operational or capital changes can make the biggest difference.
Our work focuses on measurement, evidence and clear recommendations. We do not promise health outcomes that depend on individual circumstances, and we do not sell ventilation equipment or filtration products — our role is to help your estates and leadership teams make informed decisions.

№ 02 — What we do
School-focused air quality, ventilation and environmental monitoring services.
School Air Quality Assessment
On-site assessment of classroom indoor air quality, ventilation performance and environmental conditions across your buildings.
Request an assessmentClassroom Ventilation Review
Airflow and ventilation analysis for naturally ventilated, mechanically ventilated and mixed-mode school spaces.
Ventilation assessmentCO₂ & Environmental Monitoring
Continuous classroom CO₂, temperature and humidity monitoring to identify under-ventilated rooms and overheating risk.
Explore CO₂ monitoringIndoor Air Quality Monitoring
Multi-parameter monitoring of particulates, VOCs and CO₂ across classrooms, halls and shared school spaces.
IAQ monitoringIndoor Air Quality Testing
Targeted school IAQ testing — VOCs, formaldehyde, particulates and mould — with clear, school-friendly reporting.
IAQ testingSchool Survey & Site Visit
Structured walk-through of classrooms and plant areas, with a written summary of priority actions for estates teams.

№ 03 — Environmental factors
The classroom environmental factors we measure.
Each factor below interacts with the others. Our school assessments combine short-term targeted testing with longer-term continuous monitoring where that produces a more accurate picture of daily classroom conditions.
CO₂
An indicator of classroom ventilation, linked to concentration and cognitive load.
Particulate Matter (PM2.5 & PM10)
Fine particles from outdoor sources, traffic and indoor activities.
VOCs & Formaldehyde
Emissions from furniture, cleaning products, paints and refurbishments.
Humidity & Mould Risk
Moisture balance affecting comfort, condensation and mould growth.
Thermal Comfort
Temperature stability and overheating risk in classrooms and halls.
Airflow & Ventilation
Effective fresh-air supply across naturally and mechanically ventilated spaces.
№ 04 — Healthy learning environments
From healthy classrooms to whole-school improvement.
A healthy school is more than a building that meets minimum ventilation guidance. It is one where ventilation, temperature, humidity and pollutant control are managed together — and where the school can demonstrate that management over time.
Our work supports practical improvement planning: identifying the rooms that need attention first, the operational changes (window-opening schedules, plant maintenance, occupancy patterns) that can be made quickly, and the longer-term ventilation or estate investments that justify capital spend.
