Cleaner air
Removing dust and airborne contaminants improves indoor air quality throughout your building.
Ventilation Hygiene
Comprehensive ventilation hygiene services, including ductwork and AHU cleaning, hygiene assessments and cleanliness testing in accordance with TR19® Air, helping maintain cleaner, healthier and more efficient ventilation systems.
Overview
About the service.
Clean ventilation systems are essential for maintaining healthy indoor environments, protecting air quality and supporting efficient system operation. Over time, dust, debris and contaminants accumulate within ductwork and air handling units, potentially affecting hygiene standards, airflow and overall system performance.
At VMES, we provide specialist ventilation hygiene services, including ductwork and AHU cleaning, hygiene assessments and cleanliness testing in accordance with TR19® Air. Our engineers assess system conditions, identify contamination and deliver effective cleaning solutions, supported by detailed inspections, photographic evidence and comprehensive compliance reporting.
What’s included
- Ventilation hygiene assessments
- AHU and ductwork cleaning
- Dust deposit testing
- Post-clean verification
- TR19® Air compliance reporting
How it works
From Assessment to Compliance Reporting.
A structured approach to ventilation hygiene — assessed, cleaned and documented at every stage.
01
Assess
We inspect your ventilation system, including ductwork and air handling units, to evaluate cleanliness, identify contamination and determine the appropriate cleaning requirements.
02
Plan
We establish the scope of work, assess system accessibility and agree a suitable cleaning methodology in accordance with TR19® Air and relevant industry guidance.
03
Clean
Our engineers undertake specialist cleaning of ductwork, air handling units and associated components, removing accumulated dust, debris and contamination while minimising operational disruption.
04
Verify & Report
We verify cleaning outcomes and provide photographic evidence, inspection findings and detailed hygiene reports, with certification where applicable, to support your compliance records.
Why it matters
The value of TR19® Air.
TR19® Air helps ensure ventilation systems remain hygienic, efficient and compliant, supporting healthier buildings and long-term system performance.
Improved performance
Clean ventilation systems maintain designed airflow, helping equipment operate more efficiently.
Lower operating costs
Reduced contamination places less strain on plant and equipment, helping lower energy and maintenance costs.
Compliance assured
TR19® Air certification provides recognised evidence of cleanliness for audits, insurers and compliance records.
FAQs
Common questions.
What is ventilation hygiene?
Ventilation hygiene involves inspecting, assessing and cleaning ventilation systems to control dust, debris and contamination. This includes supply and extract ductwork, air handling units (AHUs) and associated components, helping maintain indoor air quality, system efficiency and compliance with relevant industry standards.
What is a ventilation hygiene assessment?
A ventilation hygiene assessment evaluates the cleanliness of a ventilation system through visual inspections and, where appropriate, dust deposit testing. The findings help establish whether cleaning is necessary and provide documented evidence of system condition against recognised cleanliness benchmarks.
How often should ductwork be cleaned?
It depends on the system and how it’s used, but TR19® sets recommended frequencies based on risk. We’ll advise the right schedule for your sites as part of the survey.
Will the work disrupt our operations?
We plan around you — including out-of-hours and phased works where needed — to keep disruption to a minimum.
