Kitchen extract cleaning removes grease beyond the filters, along the canopy and accessible duct route. We clean systems where accumulated deposits need attention ahead of a fire-risk review or planned kitchen maintenance. Cleaning the canopy alone does not establish the condition of the duct behind the ceiling.
Kitchen Extract Cleaning
Kitchen extract cleaning for canopies and accessible grease ducts, with clear coverage of the system and protection for food areas.

Grease inside the extraction system
Bends, horizontal runs and fan sections can hold grease that filter washing never reaches.
Food-area protection
Fans are isolated where needed and food preparation areas are protected from grease and cleaning chemicals.
Grease inside the extraction system
Bends, horizontal runs and fan sections can hold grease that filter washing never reaches. We establish which access panels open onto each section and where further access is needed. Internal surfaces must tolerate the selected degreaser and tools. Inaccessible sections cannot be described as clean simply because the visible parts look satisfactory.

Isolation and protection of food areas
The fan and connected equipment need suitable isolation. We protect food preparation areas from loosened grease and cleaning chemicals, with collected material contained for disposal. Work is sequenced around kitchen use, including enough time to clean affected surrounding surfaces before food preparation resumes.
Cleaning coverage and remaining access limits
We identify the sections reached and any remaining access limits. The next cleaning interval should reflect cooking intensity and actual accumulation. Our cleaning findings support maintenance and fire-risk decisions; they do not replace fan servicing or the wider fire-risk assessment for the premises.
BESA treats kitchen grease and general ventilation cleanliness under separate specifications: TR19 Grease for grease and fire-risk management in kitchen extraction, and TR19 Air for ventilation cleanliness.
Kitchen Extract Cleaning: common questions
Is filter washing a full extract-system clean?
No. Grease can remain further along the duct and around the fan after filters are washed.
Can inaccessible ductwork be reported as clean?
Any section that cannot be reached must be identified as a limitation.
Does cleaning certify the whole kitchen is fire-safe?
No. System cleaning addresses grease deposits; the wider fire-risk assessment remains necessary.
What determines cleaning frequency?
Cooking activity and the observed rate of grease accumulation should guide the interval.
Does the kitchen need protection?
Yes. Food and preparation surfaces must be protected from released grease and cleaning products.
