TR19® Air Ventilation Hygiene & Air Duct Cleaning Support
Need to act on a ventilation hygiene report, indoor-air-quality concern, planned maintenance requirement or an inspection of general air systems?
EC Cleaners Network helps facilities and estates teams organise the requirement, approach appropriate independent ventilation-hygiene specialists and establish what inspection, cleaning and close-out information should be agreed before work begins.
TR19® Air concerns the internal cleanliness and hygiene management of general ventilation systems. Kitchen grease extraction is covered separately by TR19® Grease.
Most requirements begin with inspection, maintenance or a building-use concern.
General ventilation is different from kitchen grease extraction. The first questions are which air systems are involved, what condition information already exists, how the ductwork and plant can be accessed and what evidence the responsible team needs afterwards.
A ventilation inspection identifies contamination
Dust or other deposits may have been recorded within ductwork, plant or associated components and a competent specialist is needed to establish the appropriate next action.
Planned maintenance calls for a hygiene review
An estates or FM programme may require inspection, testing or cleaning of ventilation systems as part of the building’s maintenance regime.
Access or system records are incomplete
The system may pass through ceiling voids, risers, plant rooms or high-level areas where existing access and identification need clarifying before work is priced.
A public or occupied building needs documented close-out
Schools, healthcare premises, offices, retail environments and other occupied buildings often need clear records of what was inspected, cleaned, excluded and left outstanding.
What can a ventilation hygiene requirement involve?
The exact scope depends on the building and system. General ventilation may include supply and extract ductwork, air-handling plant, fans, grilles, diffusers, plenums and other accessible airside components. A competent specialist should establish which system is being assessed and which components fall within the agreed work.
Supply air systems
Ductwork and components distributing conditioned or outside air through the building.
General extract systems
Non-grease ventilation carrying air away from occupied or operational areas.
Air-handling plant
Accessible plant and associated airside components may need inspection or cleaning depending on the agreed scope and system condition.
Terminals, grilles & diffusers
Visible terminal components should be related back to the correct system so inspection and evidence are not disconnected from the ductwork they serve.
Access points & high-level areas
Ceiling voids, plant rooms, risers and high-level ductwork can materially affect how the work is planned and priced.
Cleaning should follow the condition of the system, not a generic assumption.
TR19® Air provides a framework for assessing and managing the internal cleanliness of ventilation systems. The appointed ventilation-hygiene specialist should determine the inspection method, condition findings and appropriate technical response for the system being considered.
Ventilation hygiene has to work around the building, not just the duct.

Retail & food-court environment
West Quay · Southampton
A busy public setting where access, working height and minimising disruption all affect specialist work planning.
High-level access
Public-area access · West Quay
Elevated work in an occupied commercial environment illustrates why safe access and operational restrictions belong in the requirement from the outset.
Hospitality buildings
The Fox · Farnham
Traditional hospitality buildings can combine occupied trading areas, older building fabric and constrained routes to fans, ducts or plant.
Heritage & unusual environments
HMS Warrior · Portsmouth
An unusual heritage environment demonstrates why access, building constraints and operational sensitivity need considering before specialist work begins.
Make the inspection basis, system boundary and reporting requirement visible.
Two contractors can appear to be quoting for “duct cleaning” while actually allowing for very different systems, inspection work, access and evidence.
The appointed specialist remains responsible for technical assessment and the proposed cleaning methodology. The customer should be able to see what system is included, how the need for cleaning has been established, what areas are accessible and what evidence will be provided.
What should come back after ventilation-hygiene work?
The exact technical report is the contractor’s responsibility, but the organisation should be able to understand which system was worked on, what was inspected or cleaned, where evidence was obtained and what remains outside the completed scope.
How is TR19® Air different from TR19® Grease?
TR19® Air addresses the internal cleanliness and hygiene management of general ventilation systems in commercial and public buildings. TR19® Grease is the separate specification concerned with fire-risk management of grease accumulation in commercial kitchen extraction systems.
Ventilation hygiene extends far beyond commercial kitchens.
TR19® Air is relevant to general ventilation systems in a wide range of occupied buildings. Sector guidance should reflect building use, occupants, access constraints, maintenance regimes and the evidence needs of the responsible facilities or estates team.
Send the ventilation report, photographs or maintenance requirement.
You do not need to diagnose the system before contacting EC. Send the building details, what has triggered the requirement, any existing inspection information, known access problems and the timescale. Those details can be organised before appropriate independent ventilation-hygiene specialists are approached.
EC Cleaners Network is operated by Search and Submit Ltd. Search and Submit Ltd does not inspect, clean, test, certify or technically approve ventilation systems. Independent contractors remain responsible for technical assessment, inspection, testing, quotations, cleaning, reporting, certification and applicable notifications.
