BREEAM Indoor Air Quality Testing

BREEAM Pre-Occupation Indoor Air Quality Testing UK for Hea 02 (VOCs, Formaldehyde and IAQ Evidence)

BREEAM Indoor Air Quality Testing provides pre-occupation evidence to support BREEAM credits under Hea 02 (Indoor air quality). Testing is typically required to demonstrate that indoor pollutant concentrations meet scheme criteria and that an Indoor Air Quality Plan (IAQP) has been implemented effectively. A robust testing programme is coordinated with the construction and fit-out programme, uses appropriate sample locations and methods, and provides a clear report suitable for BREEAM assessor submission.

When BREEAM IAQ Testing Is Required

This service is typically required where:

• A project is targeting BREEAM credits and requires pre-occupation IAQ testing
• Hea 02 requires evidence for VOCs and formaldehyde (and other criteria depending on scheme/version)
• Project teams need a testing plan that matches BREEAM timing and occupancy requirements
• There is risk from new finishes, adhesives, furnishings or fit-out emissions
• Assessor requires clear documentation and results presentation for compliance evidence

Purpose of the Service

The purpose is to provide BREEAM-aligned evidence that indoor air quality is acceptable at handover and that building operation and ventilation strategy support healthy occupancy. Testing also provides practical assurance for building owners and occupiers that the space is ready for use.

How BREEAM IAQ Testing Works in Practice

BREEAM IAQ testing succeeds when it is planned early. Testing must be scheduled when the building is sufficiently complete, ventilation systems are operational, and high-emission activities are finished. Where results are elevated, practical actions can include increased ventilation, flush-out periods, removal of sources and retesting. Where IAQ evidence is needed beyond BREEAM, see Indoor Air Quality Monitoring.

Scope and Typical Testing Elements

Scope depends on the BREEAM scheme and version. Where workplace exposure compliance is required (task-based exposure), see COSHH Air Monitoring.

• Testing plan (locations, timing, occupancy readiness, ventilation status confirmation)
• Sampling and analysis for BREEAM-required parameters (commonly including VOCs and formaldehyde)
• UKAS-accredited laboratory analysis where required by scheme/assessor expectations
• Reporting formatted for BREEAM assessor submission with clear pass/fail interpretation
• Corrective action guidance if results do not meet criteria (practical pathway to compliance)

What the Service Delivers

• BREEAM-aligned IAQ testing plan and coordination requirements
• Sampling and laboratory analysis outputs suitable for assessor evidence
• Clear report with results interpretation and compliance evidence structure
• Practical improvement actions and retesting pathway if required

What We Need From You

• BREEAM scheme and version, credits targeted, and assessor requirements
• Floor plans, ventilation strategy and intended occupancy schedule
• Fit-out programme and confirmation of completion status for high-emission activities
• Access arrangements and any building operational constraints

Limitations and Scope

IAQ testing is a snapshot at the time of sampling. Results are influenced by ventilation operation, recent fit-out activities and cleaning products. Planning and timing are critical to avoid avoidable failures and retesting.
