Early detection
Identify dust, debris and biological contamination before it develops into a more significant hygiene or maintenance issue.
Hygiene Assessments
Professional ventilation hygiene assessments, combining visual inspections, cleanliness verification and microbiological sampling to evaluate system condition and support compliance.
Overview
About the service.
Ventilation systems require regular hygiene assessments to identify contamination, monitor cleanliness and determine when cleaning or remedial works are necessary. Without routine inspections, dust and microbial contamination can accumulate, affecting indoor air quality, system efficiency and compliance with industry standards.
At VMES, we provide specialist ventilation hygiene assessments in accordance with TR19® Air and BS EN 15780. Our engineers carry out detailed inspections, cleanliness testing and contamination assessments to establish system condition and identify any required actions. Every assessment is supported by photographic evidence, detailed reporting and clear recommendations to help maintain safe, clean and compliant ventilation systems.
What we do
- Internal ventilation inspections
- TR19® cleanliness assessment
- Microbiological sampling
- Photographic condition survey

How it works
From assessment to recommendations.
A clear, accountable process — documented at every step.
01
Inspect
Our engineers carry out a detailed visual inspection of the ventilation system, assessing internal cleanliness, accessibility and the overall condition of key components.
02
Assess
We evaluate dust accumulation, debris, microbial contamination and any defects that may affect hygiene, system performance or future maintenance requirements.
03
Sample
Where required, microbiological samples are taken and submitted for laboratory analysis to assess bacterial or fungal contamination within the ventilation system.
04
Report
You receive a comprehensive report with photographic evidence, assessment findings and practical recommendations to help plan cleaning, remedial works or ongoing maintenance.
Why it matters
Understanding Your Ventilation.
Routine hygiene assessments help identify contamination before it affects indoor air quality, system performance or compliance.
Evidence based
Make informed decisions by understanding whether cleaning, remedial works or continued monitoring is the most appropriate course of action.
Improved air quality
Maintaining good ventilation hygiene supports healthier indoor environments and helps systems continue operating as intended.
Compliance support
Receive clear, documented evidence to support audits, insurers, maintenance records and wider compliance requirements.
FAQs
Common questions.
What is a ventilation hygiene assessment?
A ventilation hygiene assessment is a detailed inspection of your ventilation system to evaluate its internal cleanliness and overall condition. It helps identify contamination, determine whether cleaning is required and provides clear recommendations for future maintenance.
Do you carry out microbiological testing?
Yes. Where required, we can undertake microbiological sampling to assess bacterial or fungal contamination within ventilation systems. Samples are analysed by an accredited laboratory and included within your final report.
Does the assessment include cleaning?
No. A hygiene assessment is an inspection service designed to evaluate the condition of your ventilation system. If cleaning or remedial works are recommended, these can be quoted separately.
What do I receive after the assessment?
Every assessment includes a detailed report with photographic evidence, cleanliness observations, inspection findings and practical recommendations, providing a clear record of your system’s condition for maintenance planning and compliance.
