Carlisle · 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 Carlisle, and certify it to the TR19 Grease standard your insurer expects.
Carlisle
Carlisle rates around 2,850 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.
Kitchens across Carlisle work out of tight, mixed premises - English Street, Botchergate, Lanes - their extract snaking through concealed voids to roof-mounted fans. We take the whole run to the TR19 Grease standard, hood to fan, reaching the horizontal legs and vertical risers a canopy wipe never touches.
The same crews clean dry ventilation and air-handling ductwork in offices, schools and civic buildings, plus the combustible lint runs behind hotel and care-home dryers. High-turnover sites - the University of Cumbria, the Cumberland Infirmary, Brunton Park and the city hotels - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Carlisle insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Because the standard is written around film thickness, it sets the depth that triggers a clean and re-test. In the mixed roof spaces around English Street and Lanes, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Carlisle run through existing hatches and new ones we cut, clean back to bright metal, take before-and-after grease-depth figures at set points, and certify it to TR19 Grease with those depths on the 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 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 Carlisle hotels, care homes and gyms.
On the ground in Carlisle
We are in Carlisle's ductwork and plant every week. The proof is the jobs, not the stock photos.
A rural hospital kitchen in Carlisle had viscous grease spreading along the horizontal extraction runs and up the vertical discharge chimney. We fitted two new fire-rated access panels, hand-scraped the heavy grease and treated the lines with an enzyme degreaser, bringing the ductwork back to bare metal for the NHS food-safety and fire standard. The work windows were arranged around the patient meal-distribution times.
When it is due
Ductwork rarely warns you politely. In a busy Carlisle kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto an English Street line, a rim of grease at the filters, or a Carlisle insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Botchergate 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 Carlisle 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 Lanes 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 Carlisle fire logbook.
Why it matters
Three duties push every Carlisle 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 Carlisle 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 an English 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. A current TR19 Grease certificate is the evidence your Carlisle 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. A food hygiene visit from Cumberland Council weighs the physical state of the premises, ventilation counted within it. A grease-blocked extract can pull down the rating an Environmental Health Officer sets, quite apart from the stale smell and the tired airflow your staff work beneath all shift.
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 English Street kitchen sits in a tighter band than a daytime Botchergate cafe. We measure the grease load and confirm your interval.
Yes. The fan at the top of a Lanes 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.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence an English Street operator's insurer and fire risk assessor expect.
Yes. We work overnight, early mornings and closing days for the English Street and Botchergate kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes. We clean the dry ductwork and air-handling in Carlisle offices, schools and public buildings, and the lint-heavy laundry ducts in the Cumbria hotels and care homes, alongside kitchen grease ducts.
We fit compliant access panels where the ductwork has none, so every internal section can be reached, cleaned, inspected and certified - common in the older Lanes conversions where the run was boxed in with no hatches.
Yes - from English Street and Botchergate kitchens to the offices, schools and industrial units across Carlisle and the wider Cumbria.
