TR19 Compliance Testing
Trusted since 1999 · Proven delivery partner
TR19 is the recognised industry standard for assessing the cleanliness of ventilation ductwork. Green Air Monitoring delivers independent TR19 assessments for commercial buildings, providing the evidence needed for compliance, insurance requirements, and fire risk management.
What TR19 Requires
TR19 sets out the methodology for assessing ventilation system cleanliness, including visual inspection, surface sampling, and photographic documentation. Systems are classified as acceptable, marginal, or unacceptable based on contamination levels.
- Visual inspection of accessible ductwork sections
- Surface contamination measurement (gravimetric analysis)
- Photographic documentation of duct condition
- Classification against TR19 cleanliness criteria
- Remediation recommendations where needed
Why TR19 Matters
TR19 compliance is required by insurers, expected by HSE, and referenced in fire risk assessments. Dirty ductwork can harbour bacteria, spread fire, increase energy costs, and deliver contaminated air to occupied spaces. Regular assessment is both a legal and practical necessity.
