Why a structured assessment matters in educational buildings
School buildings are unusually demanding indoor environments. Class sizes are high, room volumes are often modest, occupancy varies hour by hour, and the people inside are children whose comfort, concentration and respiratory health are sensitive to the conditions around them.
Yet most schools have never had a structured air quality assessment. Concerns surface piecemeal — a damp corner here, a stuffy science lab there, a refurbishment that does not feel right — and decisions get made without a coherent picture of how the buildings perform. An assessment provides that picture.
Common reasons schools commission an assessment
There is rarely a single reason. Most schools come to us with a combination of triggers that have accumulated over a term or year.
- Staff or parent concerns about stuffiness, headaches or tiredness
- Visible condensation, persistent damp or suspected mould
- A refurbishment, new wing or modular building that feels different
- CO₂ monitors showing high or variable readings
- An Ofsted, HSE or insurer recommendation
- Preparation of a CIF bid, capital programme or trust estates strategy
How our school air quality assessment works
We begin with a scoping conversation: which buildings, which rooms, what has been done before, and what decisions the assessment needs to support. We then carry out an on-site walkthrough with the estates lead, reviewing fabric, ventilation provision, occupancy patterns, cleaning regimes and any obvious sources of pollution.
Where measurement is helpful at this stage we deploy short-term sensors or take spot readings, but the focus of the assessment is interpretation — joining the dots between the building, how it is used and the air people breathe. The written report explains what was reviewed, what was found and what to do next.
What we review during the assessment
- • Building age, fabric, layout and use
- • Ventilation strategy (natural, mechanical, mixed)
- • Occupancy density and timetabling patterns
- • Existing complaints and incident history
- • Cleaning, maintenance and refurbishment activity
- • Outdoor air exposure, traffic and intakes
- • Indicative CO₂, temperature and humidity readings
Recommendations and outputs
- • Written assessment report with executive summary
- • Room-by-room findings and risk indicators
- • Quick wins (operational and behavioural)
- • Targeted testing or monitoring scope
- • Ventilation or fabric improvement options
- • Evidence pack for CIF bids and capital cases
Suitable schools and settings
- Single-site primary and secondary schools
- Multi-academy trust estates portfolios
- Local authority school estates teams
- Independent schools and sixth forms
- Nurseries and early-years providers
- SEND schools with specific comfort needs
- Newly refurbished or extended buildings
- Schools responding to parental or staff queries
Frequently asked questions
How is an assessment different from air quality testing?+
Testing produces measured pollutant values. An assessment is consultative: we investigate why the air feels stuffy, damp or stale, review the building and how it is used, and recommend the right combination of testing, monitoring and remedial work. Most schools benefit from an assessment first so the testing scope is the right shape.
Do you visit the school as part of the assessment?+
Yes. A specialist walks the buildings with the estates lead or business manager, focusing on rooms of concern, the ventilation strategy and how spaces are actually used during the teaching day. Photographs and notes form part of the written deliverable.
Can you help with complaints from parents or staff?+
Often. Many assessments are triggered by a specific complaint — persistent musty smell, repeated headaches, condensation, suspected mould or concerns about a refurbishment. We document the issue, investigate the contributing factors and produce a balanced response the school can share.
Do you provide a written report?+
Always. The deliverable is a written assessment report tailored to school decision-makers, with an executive summary, findings, prioritised recommendations and suggested next steps such as targeted testing, continuous monitoring or ventilation works.
Can the assessment feed into a refurbishment or condition survey?+
Yes. Findings can be aligned with CIF bids, capital programmes, condition surveys, BB101 reviews, and trust-wide estates planning, so air quality is considered alongside roof, fabric and M&E priorities.
