Penzance · 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 Penzance, and certify it to the TR19 Grease standard your insurer expects.
Penzance
Penzance rates hundreds of 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 - Market Jew Street, Chapel Street, Morrab Road - 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.
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 - hospital kitchens, college refectories, hotel and pub kitchens and the busy harbour-side takeaways - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Penzance 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 Market Jew Street and Morrab Road, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Penzance 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 Penzance hotels, care homes and gyms.
On the ground in Penzance
We are in Penzance's ductwork and plant every week. The proof is the jobs, not the stock photos.
The laundry exhaust at a long-established Penzance holiday park was lined the whole way with compacted lint, and the external vent flap had all but seized shut. We brushed and vacuumed the run from one end to the other and made sure that outside flap was swinging fully open again. The dryers ran cooler and cleaner afterwards, with the wash turnarounds picking up over the following days, and we left everything tidied up behind us. The site's golden retriever supervised the whole job from the top of the stairs.
When it is due
Ductwork rarely warns you politely. In a busy Penzance kitchen these are the tells.
Watch for steam that hangs in the room, cooking smells creeping back over the tables, a canopy weeping onto a Market Jew Street line, grease crusting at the filter rims, or a Penzance insurer or fire assessor calling for a TR19 certificate you do not hold. How often it needs doing rides on the cooking load - a hard-frying Chapel Street kitchen far more than a quiet daytime cafe - and the certificate fixes that interval, so the next clean is planned, not chanced.
How it runs
Inspect the full Penzance 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 Morrab Road 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 Penzance fire logbook.
Why it matters
Three duties push every Penzance 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 Penzance 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 Market Jew 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. To a Penzance insurer a current TR19 Grease certificate is the proof the extract has been kept up. Let it lapse and a fire claim can be scaled back or declined outright - the kind of gap nobody wants to find with the kitchen already gutted.
Hygiene and environmental health. When Cornwall Council carries out a food hygiene inspection it judges the physical state of the premises, and ventilation is part of that. A grease-choked extract can pull down the rating an Environmental Health Officer gives, on top of the odour and the weakening airflow your staff put up with.
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 Market Jew Street kitchen sits in a tighter band than a daytime Chapel Street cafe. We measure the grease load and confirm your interval.
Yes. We work overnight, early mornings and closing days for the Market Jew Street and Chapel Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes. The fan at the top of a Morrab Road 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 Penzance run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Chapel Street cookline is back in service for the next shift.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Market Jew Street operator's insurer and fire risk assessor expect.
Yes - from Market Jew Street and Chapel Street kitchens to the offices, schools and industrial units across Penzance and the wider Cornwall.
Yes. We clean the dry ductwork and air-handling in Penzance offices, schools and public buildings, and the lint-heavy laundry ducts in the Cornwall hotels and care homes, alongside kitchen grease ducts.
Local knowledge
For generations Penzance and Newlyn cured pilchards for export, salting and pressing the fish in cellars and works like Tolcarne before the trade gave way to fresh landings and processing. Modern premises hide their dust and grease inside sealed ductwork instead, where debris builds unseen until airflow fails or fire finds a path. We clean and inspect ventilation and extract ductwork across the town, then hand over photographic before-and-after evidence of every run.
