How we do it

Grease builds up inside kitchen extract ducts and is a serious fire risk. BESA TR19 Grease recommends minimum cleaning intervals of every 3 months for heavy use (12 to 16 hours a day), 6 months for moderate use and 12 months for light use, with mean grease deposits kept below 200 microns between cleans and anything at 500 microns or more cleaned straight away. General ventilation ductwork collects dust and debris that reduce airflow and air quality; TR19 Air covers inspection and cleaning of these systems.
