Indoor Air Quality in the Workplace: The Hidden Risk Affecting Productivity

Indoor air quality (IAQ) is increasingly recognised as a critical factor in workplace health, comfort, and productivity. In offices, commercial buildings, and public spaces, poor IAQ can develop gradually and often goes unnoticed until it begins to affect occupants. 

Common causes include inadequate ventilation, elevated carbon dioxide (CO2) levels, mould growth, and the accumulation of airborne pollutants such as dust, volatile organic compounds (VOCs), and biological contaminants. These issues can lead to symptoms including fatigue, headaches, irritation of the eyes and throat, and reduced cognitive performance. 

In the UK, IAQ is closely linked to broader occupational health responsibilities, particularly under regulations that require employers to provide a safe working environment. While not always explicitly regulated in the same way as industrial exposures, IAQ assessments are increasingly being used to demonstrate due diligence and support employee wellbeing strategies.

An effective IAQ investigation typically involves air sampling, ventilation performance assessment, and identification of pollutant sources. This provides a clear, evidence-based understanding of indoor conditions and supports targeted improvements. 

As we move through 2026, IAQ is becoming a key consideration in the design and management of “healthy buildings”. Organisations are recognising that improving air quality is not just about compliance — it directly impacts productivity, absenteeism, and overall workplace satisfaction.
