How to prepare for a TR19-focused inspection
A useful TR19-focused visit starts with accurate information about the extraction route. Before attendance, the site contact should identify every canopy and confirm whether several cooking areas connect to the same duct system. Previous cleaning reports, schematic drawings and photographs can reveal concealed risers, access doors and roof-mounted equipment. The cooking line must be switched off and cool before cleaning begins, while alarms, gas isolation, electrical isolation and building permits should be managed by the responsible people on site. If the system passes through a ceiling void, neighbouring unit or landlord-controlled plant area, permission and keys should be organised in advance. These details affect the safe working method and the realistic scope. They also reduce the risk of a contractor arriving to find that a fan, riser or discharge point cannot be reached. Where access is incomplete, the report should state the limitation clearly and recommend a practical next step, such as installing a suitable access panel or arranging safe high-level access.
What a useful TR19 cleaning record should show
The final record should identify the premises, date, system and components included in the agreed work. Photographs are most useful when they relate to named locations such as the canopy plenum, first duct section, vertical riser, fan housing and discharge. The report should separate areas cleaned from areas inspected only, and should never imply full-system coverage if concealed sections were unavailable. Observations about damaged filters, missing access, loose components or possible mechanical faults should be described without confusing cleaning with repair. The operator can then share the record with the responsible person, landlord, facilities team or insurer as part of wider maintenance management. Cleaning evidence does not replace a fire-risk assessment, insurance obligations or statutory duties. Its value is that it creates a clear history of the accessible extraction system, supports discussion about future frequency and helps the next visit begin with better information. Duct Clean London can discuss planned intervals after reviewing kitchen activity, previous reports and actual deposit conditions.
