Duct cleaning (TR19 Grease and Air)
Kitchen extract and ventilation duct cleaning with photo reports for insurers.
Guide
TR19 frequency
Under BESA TR19 Grease, kitchen extract systems should be cleaned at least every 3 months for heavy use (12 to 16 hours a day), every 6 months for moderate use (6 to 12 hours) and every 12 months for light use (2 to 6 hours).
Grease deposits inside ducts are a fire risk and can carry fire through the building. Mean deposits should stay below 200 microns, and anything at 500 microns or more needs cleaning straight away.
Before-and-after photos, deposit measurements, a summary of work and any areas that could not be reached.
Many insurers expect cleaning to a recognised standard and may ask for reports, particularly after a fire.
No. Filters catch some grease, but the canopy plenum, ductwork and fan also collect deposits that only a full clean removes.
Yes. Most kitchen cleans are done outside trading hours.
