TR19 Grease · UK-Wide · 24/7
We clean the full commercial duct run - grease, dry and laundry ductwork, canopy to roof fan - for kitchens and industrial sites across the UK, and certify it to the TR19 Grease standard your insurer expects.
The risk
Every commercial kitchen that fries, grills or chars sends grease into its extract ductwork - and the concealed runs a canopy clean never reaches are where it builds toward a fire.
Beneath the extract canopy, the ductwork carries combustible grease from the cookline through long horizontal and vertical runs to the roof fan. A canopy and filter wipe-down leaves those hidden sections untouched. We clean the complete run to the TR19 Grease standard - canopy to fan - for restaurants, takeaways, pubs, hotels, schools, care homes, hospitals and production kitchens across the UK.
The standard
TR19 Grease is the benchmark insurers and fire risk assessors expect. It covers the whole extract system, measured - not just the parts you can see.
Grease is measured by thickness, and the standard sets the level at which a system must be cleaned and re-tested. A canopy and filter wipe-down leaves the ductwork itself - the long concealed runs where grease accumulates and a fire travels - untouched. We access the full run through existing and newly fitted inspection hatches, clean to bare metal, record before-and-after grease readings at set points, and issue a TR19 Grease certificate with a post-clean depth record.
By system
The fire risk. Fried-food extract coats duct walls in combustible grease; cleaned canopy to fan and certified to TR19 Grease.
Supply and general extract carrying dust and debris that throttles airflow and spreads contamination; cleaned to TR19.
The hidden one. Tumble-dryer and industrial-launderette ducting packs with lint - highly combustible - in hotels, care homes, gyms and commercial laundries.
When it is due
Ductwork rarely warns you politely. These are the tells.
Smells pushing back into the kitchen, a canopy that drips, extraction that no longer pulls, visible grease at the filter edges, or an insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - heavy frying needs it far more often than light cooking - and your certificate states the interval, so the next clean is never a guess.
How it runs
Inspect the full run, find the access gaps, agree scope and frequency.
Fit inspection hatches where the run is sealed, protect the kitchen.

Why it matters
Three duties push every operator to keep ductwork clean, and they reinforce one another.
Fire safety law. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for a premises must assess and manage fire risk. A grease-laden duct is one of the most serious risks in any catering building, because a flare-up on the cookline can travel the ductwork and spread fire through concealed voids. The Health and Safety at Work etc. Act 1974 and the Health and Safety Executive reinforce the same duty of care.
Insurance. A current TR19 Grease certificate is the evidence your insurer expects. Without it, a fire claim can be reduced or refused outright - an expensive gap to find after the event.
Hygiene and environmental health. Food hygiene inspections assess the physical condition of premises, ventilation included. A grease-clogged system can count against the rating an Environmental Health Officer awards, quite apart from the smell and the falling extract performance your staff have to work in.
TR19 Grease sets it by daily cooking hours: roughly every three months for heavy use of 12 to 16 hours a day, every six for moderate use, every twelve for light use. We measure the grease load and confirm your interval.
The full run, from the canopy through the concealed horizontal and vertical ductwork to the roof fan - the hidden sections a canopy-only clean leaves loaded with grease.
We fit compliant access panels where the ductwork has none, so every internal section can be reached, cleaned and inspected, then certified.
Yes. Lint-heavy laundry ducts and dry ductwork carry their own fire and air-quality risk. We clean and certify these alongside kitchen grease ducts.
