Grease-laden ductwork is one of the leading causes of commercial kitchen fires in the UK. TR19 Grease compliance isn't just a legal standard — it's what stands between your business and a catastrophic fire, a voided insurance policy, and a failed inspection.
Every commercial kitchen operator in the UK has a legal duty to maintain their extract system in a clean, fire-safe condition. Failure to do so carries serious consequences.
Grease accumulation in ductwork is highly flammable. A kitchen fire that enters an unclean duct system can spread rapidly through an entire building, bypassing fire compartmentation.
LEADING CAUSE OF COMMERCIAL FIRESMost commercial kitchen insurance policies contain a clause requiring TR19-compliant cleaning at specified intervals. Without documented proof, your claim can be rejected outright.
POLICY INVALIDATIONThe Responsible Person under the Fire Safety Order 2005 must ensure extract systems are maintained. Failure is a criminal offence — not just a civil matter.
CRIMINAL LIABILITYTR19 Grease is the industry standard published by BESA (Building Engineering Services Association) for the cleaning of kitchen extract ventilation systems. It replaced the older TR19 document specifically to address grease contamination in commercial kitchens.
TR19 Grease sets specific acceptable grease deposit levels — measured in microns — for different parts of the extract system. Your cleaning contractor must test and record these levels before and after cleaning.
The standard requires photographic documentation of all accessible areas, including before and after images. Without this, your cleaning certificate has no evidential value.
Cleaning frequency is determined by the type and volume of cooking. Heavy use kitchens (e.g. fast food, pub kitchens) require quarterly cleaning. Lower usage may permit annual cleaning.
Every clean must be accompanied by a Post-Work Verification Report (PWVR) confirming grease levels are within the standard. This is your legal proof of compliance.

TR19 Grease sets frequency based on cooking type and volume. As a guide: heavy use (fast food, pub kitchens) = quarterly; moderate use (restaurants, hotels) = every 6 months; light use (offices, schools) = annually. We'll assess your kitchen and recommend the correct frequency.
