TR19 Cleaning Standards: Grease, Air & Report Checks
TR19 Grease and TR19 Air apply to different ventilation hygiene requirements. Identify the system first, then check that the contractor report describes the work, evidence and limitations for that system.
This guide explains the standards and how to read an existing cleaning record. For arranging work and the documents to agree before appointment, use our TR19 cleaning certificate and post-clean report page.
Do not read the certificate in isolation. Start with the premises, the system, the contractor scope and the supporting report.
Which TR19 standard applies?
- TR19 Grease: kitchen extract systems carrying cooking grease and the associated fire-risk management.
- TR19 Air: internal cleanliness and hygiene management of general ventilation systems.
- The report: identify the premises, system, completed scope and any inaccessible sections before relying on the document.
BESA lists a March 2026 edition of TR19 Air. Ask the appointed contractor to identify the applicable specification and reporting scope in its proposal. This overview does not reproduce the full technical specifications.
For the legal distinction, see whether TR19 is a legal requirement. For arranging extraction work, see kitchen extract cleaning.
Start with the terminology
Four common misunderstandings about a TR19 certificate.
The document can be useful evidence, but its value depends on the work and information behind it. A certificate should not be allowed to obscure an incomplete scope, inaccessible system or different technical requirement.
“TR19” is treated as one system
TR19® Grease concerns grease-related fire-risk management in commercial kitchen extraction. TR19® Air is the separate specification for general ventilation hygiene.
A certificate is treated as proof of the entire system
The underlying report still needs to show which parts of the relevant extraction or ventilation system were actually included.
A partial clean is mistaken for a full clean
Access problems can prevent sections from being inspected, cleaned or verified. Those limitations need to remain visible.
The certificate is treated as legal approval
TR19® is an industry specification. A contractor document does not replace statutory duties, a fire-risk assessment, engineering judgement or an insurer’s own requirements.
What document are you looking at?
Certificate, report and VHR notification are related; but they are not interchangeable.
The useful question is not simply “do we have a certificate?” It is “what work does this document evidence, on which system, and what other report information accompanies it?”
TR19® Grease
The BESA specification concerned with managing grease-related fire risk within commercial kitchen extraction systems.
TR19® Air
The current separate BESA specification for internal cleanliness and hygiene management of general ventilation systems.
Post-clean report
The contractor record should help the client understand the system, work undertaken, supporting evidence, limitations and outstanding actions.
VHR notification
Where applicable, an approved Vent Hygiene Register contractor can notify qualifying completed works through the VHR process.
Full or partial clean
The documentary status should reflect whether the relevant instructed system was completed or whether sections remained inaccessible or outside the completed scope.
Insurance evidence
A contractor record can support an insurance file, but the insurer or broker determines what the particular policy, endorsement or risk action requires.
Reading the evidence
A useful certificate should lead you back to an identifiable system and an understandable piece of work.
If you cannot establish which kitchen, duct route or ventilation system the document relates to, the next step is clarification rather than assuming that the whole premises has been dealt with.
Premises
Does the record identify the correct site and kitchen?
System
Can the canopy, ductwork, fan or relevant ventilation system be identified?
Date & contractor
When was the work completed and which legal business carried it out?
Status
Was the work recorded as full, partial or subject to outstanding limitations?
Why system context matters
A photograph is useful only when you can understand what part of the system or kitchen it represents.
These EC project photographs illustrate why a certificate or group of close-up images needs physical context. They are not presented as examples of any particular contractor reporting system or as evidence about the compliance status of the premises shown.
Premises context
Identify the kitchen first
A portfolio may contain several kitchens, service areas or extract systems. The report needs to relate evidence to the correct premises and asset.
Different workstreams
Kitchen equipment is not the extract system
Equipment cleaning, deep cleaning and grease-extract hygiene can take place during the same shutdown while remaining different technical scopes.
Contractor attendance
Attendance and completion are different facts
A contractor may attend during the agreed shutdown but still encounter an inaccessible section or unexpected system condition.
Visible condition
A clean-looking kitchen does not describe concealed ductwork
Visible cleanliness is useful operationally but does not by itself establish the condition or treatment of concealed extraction-system sections.
Five-step certificate check
Read the document backwards from the physical requirement.
A certificate becomes more useful when you can connect it to the original instruction and contractor report.
This does not require the customer to make its own technical judgement. It simply helps establish whether the documentary chain is sufficiently clear to know what happened and whether another question or action remains.
1 · What triggered the work?
Routine maintenance, insurer requirement, fire-risk action, previous report, acquisition or another defined reason.
2 · What system was instructed?
Identify the kitchen extract or general ventilation system and intended system boundary.
3 · What did the contractor report?
Read the work summary, photographs, measurements where applicable, exclusions and recommendations.
4 · Was anything incomplete?
Look for partial-clean wording, inaccessible ductwork, missing access and outstanding remedial actions.
5 · What document closes the record?
Retain the contractor report, relevant certificate or notification and any professional response required by the original trigger.
What good evidence can establish
The documentation should make the contractor’s own work understandable.
The strongest record provides traceability from the original requirement through physical delivery to the contractor’s reported outcome.
Who carried out the work
The contractor and, where recorded, relevant technician or responsible person can be identified.
Which system was involved
The premises and relevant extraction or ventilation system are sufficiently identifiable.
What work was completed
The report describes the relevant inspection, cleaning or related physical activity.
What evidence was recorded
Photographs, measurements and other relevant verification remain connected to the report.
What remained outstanding
Exclusions, inaccessible areas and recommendations remain visible rather than being lost after issue of a certificate.
What it does not automatically establish
A TR19 document is not a universal premises-compliance certificate.
Different organisations remain responsible for different decisions. Contractor evidence can inform those decisions without replacing them.
Statutory approval
TR19® is an industry specification rather than primary legislation or a statutory operating licence.
Overall fire safety
A kitchen-extract report does not replace the premises fire-risk assessment or other fire-safety controls.
Insurance acceptance
The insurer or broker decides whether the evidence satisfies its own policy or risk-improvement requirement.
Ventilation design
A cleaning certificate does not establish that a system has been designed or commissioned correctly.
Food hygiene approval
TR19 documentation does not replace the food business’s wider food-safety and hygiene responsibilities.
Who may need the evidence?
The same contractor report may form part of several different management records.
The document can support maintenance and risk-management processes, but each recipient should interpret it within their own role rather than treating the certificate as a substitute for that role.

Frequently asked questions
What is the difference between TR19 Grease and TR19 Air?
TR19 Grease addresses grease accumulation and associated fire risk in kitchen extraction. TR19 Air addresses internal cleanliness and hygiene management of general ventilation systems.
What should I check in a TR19 cleaning report?
Check the site and system identity, contractor, work date, instructed scope, evidence, completion status, access exclusions and outstanding actions. Ask the contractor to clarify missing or technical information.
Does a partial clean cover inaccessible ductwork?
The report should make clear which sections were completed and which were inaccessible or excluded. A document for completed areas should not obscure outstanding work elsewhere.
Does a VHR entry replace checking the contractor scope?
No. Check the contractor current registration and relevant scope where required, then agree the actual system, access, reporting and any applicable notification for the job.

Independent appointed contractors remain responsible for technical assessment, physical delivery, verification, reporting, certification and applicable Vent Hygiene Register notifications. Customers should verify current contractor registration and scope where VHR status is required for the proposed work.
TR19® Grease and TR19® Air are BESA specifications for different ventilation-hygiene workstreams. A certificate, report or VHR notification should be read in relation to the specific system, scope and stated work status. It does not by itself establish overall statutory, fire-safety, insurance, food-hygiene or engineering compliance.
