Ventilation Surveys & Indoor Air Quality Assessments

Why Ventilation Matters

As homes become more airtight through insulation and draught-proofing programmes, adequate ventilation becomes increasingly critical. Inadequate ventilation leads to elevated humidity, condensation, mould growth and poor indoor air quality — all of which directly affect tenant health and wellbeing.

For housing associations managing retrofit and decarbonisation programmes, ventilation assessment is not optional — it is a fundamental part of responsible stock management and PAS 2035 compliance.

Our Ventilation Survey Service

• Assessment of existing ventilation provision against current standards
• Identification of inadequate or failed ventilation systems
• CO2 monitoring and indoor air quality testing
• Recommendations for improvement — from passive ventilation to MVHR (Mechanical Ventilation with Heat Recovery)
• Integration with damp and mould assessments
• PAS 2035 aligned reporting

Indoor Air Quality Assessments

Indoor air quality (IAQ — a measure of the air environment within a building as it relates to the health and comfort of occupants) assessments go beyond ventilation to look at the full range of factors affecting the air inside a home — including humidity, CO2 levels, VOCs (Volatile Organic Compounds) and particulates. This is particularly relevant for properties with vulnerable occupants or where health complaints have been raised.

Awaab's Law & Ventilation

Inadequate ventilation is frequently identified as a contributing factor in damp and mould cases. Our ventilation surveys provide the independent, evidence-based assessment housing associations need to demonstrate they are addressing root causes under the applicable hazard-response requirements.
