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 can appear clean externally while contamination develops internally over many years. Without inspection, it’s difficult to determine whether a system remains hygienic, requires cleaning or presents a potential risk to building occupants.
Our hygiene assessments provide a detailed evaluation of the internal condition of ventilation systems, helping building owners understand cleanliness levels and make informed maintenance decisions.
What’s included
- Internal ventilation inspections
- TR19® cleanliness assessment
- Microbiological sampling
- Photographic condition survey
- Hygiene report & recommendations
Beyond the Surface
Complete System Visibility.
Every assessment is designed to build a clear understanding of the internal condition of your ventilation system. Using specialist inspection equipment, our engineers assess ductwork, air handling units, grilles, filters and associated components for dust accumulation, microbial growth, moisture, corrosion and physical defects.
Where required, microbiological sampling can be undertaken to identify bacterial or fungal contamination that cannot be confirmed through visual inspection alone, providing a more complete understanding of system hygiene.
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.
Clear Reporting
Evidence You Can Trust.
Every assessment is supported by detailed photographic evidence, cleanliness observations and practical recommendations tailored to your ventilation system. Our reports present the findings in a clear, structured format, making it easy to understand the overall condition of your system.
Whether no action is required, routine cleaning is recommended or remedial works are identified, you’ll receive practical guidance to help prioritise maintenance, plan future works and make informed decisions with confidence.
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.
Where we work
Sectors we serve.
We clean and certify ventilation systems across a wide range of commercial and industrial settings.
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.
