Liverpool · TR19 Grease
We clean the full commercial duct run - grease, dry and laundry ductwork, canopy to roof fan - for kitchens, offices and industrial sites across Liverpool, and certify it to the TR19 Grease standard your insurer expects.
Liverpool
Liverpool rates around 4,400 food premises, and behind a large share sits an extract duct a canopy clean never reaches - plus the dry ductwork and air-handling that keep its offices and public buildings running.
The city's kitchens sit in tight, mixed stock - Bold Street, Castle Street, Ropewalks - with long concealed duct runs up to roof fans. We clean the full run to the TR19 Grease standard, canopy to fan, including the horizontal and vertical sections a canopy-only clean leaves coated.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Liverpool schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - the four universities, the Royal Liverpool University Hospital, Anfield and the M&S Bank Arena and the city hotels - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Liverpool insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard works in grease-film thickness, fixing the depth at which a run must be cleaned and re-tested. In the shared roof voids around Bold Street and Ropewalks, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Liverpool run through existing and newly cut inspection hatches, strip it to bare metal, log grease-depth readings at fixed points before and after, and issue a TR19 Grease certificate with the post-clean depths recorded.
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 in offices and public buildings, carrying dust and debris that throttles airflow and loads the air-handling unit; cleaned to TR19.
The hidden one. Tumble-dryer ducting packs with lint - highly combustible - in Liverpool hotels, care homes and gyms.
On the ground in Liverpool
We are in Liverpool's ductwork and plant every week. The proof is the jobs, not the stock photos.
A secondary school in Liverpool had us in over the summer holidays for its washroom extract - the grilles and the main branch lines were packed with dust, lint and paper-towel fibre and the air had gone stale. We cleared every grille by hand, ran motorised rotary brushes through the rigid spiral ducting and pulled the debris out on a HEPA negative-air machine. The airflow came back across all the washrooms and the stale, damp smell went with it.
When it is due
Ductwork rarely warns you politely. In a busy Liverpool kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Bold Street line, a rim of grease at the filters, or a Liverpool insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Castle Street kitchen needs it far more often than a quiet cafe - and your certificate sets the date, so nothing is left to chance.
How it runs
Inspect the full Liverpool run, find the access gaps in the concealed sections, agree scope and frequency.
Fit inspection hatches where the run is sealed - common in the older Ropewalks conversions - and protect the kitchen.
Canopy to roof fan, down to bare metal, with before-and-after grease-depth evidence.
TR19 Grease certificate, grease-depth record and next-due date for your Liverpool fire logbook.
Why it matters
Three duties push every Liverpool 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 Liverpool 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 a Bold Street cookline can travel the ductwork and spread fire through concealed voids. The Health and Safety at Work etc. Act 1974 and the HSE reinforce the same duty of care.
Insurance. Your Liverpool insurer expects a current TR19 Grease certificate as proof the duct is clean. Without one, a fire claim can be cut back or turned down altogether - a costly thing to find only after a fire.
Hygiene and environmental health. Liverpool City Council 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.
It is set by cooking hours under TR19 Grease - roughly every three months for heavy use of 12 to 16 hours a day, every six for moderate, every twelve for light. A hard-frying Bold Street kitchen sits in a tighter band than a daytime Castle Street cafe. We measure the grease load and confirm your interval.
Yes. We work overnight, early mornings and closing days for the Bold Street and Castle Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Bold Street operator's insurer and fire risk assessor expect.
Yes. The fan at the top of a Ropewalks or city-centre riser is where grease throws off the blades and the run ends - we degrease it and its housing, because a loaded fan is what finally stops a system pulling.
Little, if it is planned. We survey the Liverpool run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Castle Street cookline is back in service for the next shift.
Yes. We clean the dry ductwork and air-handling in Liverpool offices, schools and public buildings, and the lint-heavy laundry ducts in the Merseyside hotels and care homes, alongside kitchen grease ducts.
Yes - from Bold Street and Castle Street kitchens to the offices, schools and industrial units across Liverpool and the wider Merseyside.
