To make indoor air quality understandable, measurable and actionable. The science is rich and the standards are mature — what has been missing for most UK building owners and occupants is independent, plain-English guidance that links the evidence to specific decisions. That is what we publish, and what we deliver in the field.

Our mission
02
Our expertise
Our work draws on building physics, environmental health, HVAC engineering and analytical chemistry. We work to UK and international reference frameworks — WHO indoor air quality guidelines, BS EN 16798-1, CIBSE TM40 and Guide A, BREEAM Hea 02 and the WELL Building Standard — and explicitly cite them in every report.
03
What we deliver
IAQ testing. Multi-parameter measurement against published thresholds.
IAQ monitoring. Continuous sensor networks with reporting and alerting.
Ventilation assessment. Airflow, CO₂ tracer and HVAC inspection.
VOC testing and mould air testing. Laboratory-grade speciated and biological analysis.
Air quality inspection. Whole-building diagnostic and remediation strategy.
04
Why independence matters
We do not sell ventilation equipment, filters or remediation products. Our reports recommend what the building needs, not what we have to sell. That is the only model that aligns our incentives with the people we serve.
