Truro · 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 Truro, and certify it to the TR19 Grease standard your insurer expects.
Truro
Truro 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.
Right across Truro, from Boscawen Street through Pydar Street to Lemon Street, cooklines share tight roof space and vent through concealed ducting few operators ever see inside. We clean that entire path to the TR19 Grease standard, canopy through to fan, taking in the level pulls and the risers where grease settles thickest and a fire would run.
Beyond the kitchens, we clean the dry ductwork and air-handling in offices, schools and public buildings, and the lint-heavy laundry ducts in hotels and care homes. High-output kitchens - hospital kitchens, college refectories, hotel and pub kitchens and the busy city-centre takeaways - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Truro 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 Boscawen Street and Lemon Street, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Truro 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 Truro hotels, care homes and gyms.
On the ground in Truro
We are in Truro's ductwork and plant every week. The proof is the jobs, not the stock photos.
At a refurbished leisure centre in Truro the changing-room extract had all but stopped, with dust matting the ceiling grilles. We took the intake grilles off and washed them, brushed out the branch ducting and cleaned the inline extract fan. Extraction came back across the staff toilets and the damp, stale smell left with it, and the client rebooked us there and then. We left them paired before-and-after images and a service record for the H and S folder.
When it is due
Ductwork rarely warns you politely. In a busy Truro 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 Boscawen Street line, grease crusting at the filter rims, or a Truro 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 Pydar 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 Truro 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 Lemon Street conversions - and protect the kitchen.

Why it matters
Three duties push every Truro 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 Truro 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 Boscawen 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 Truro 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. 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 Boscawen Street kitchen sits in a tighter band than a daytime Pydar Street cafe. We measure the grease load and confirm your interval.
Yes - from Boscawen Street and Pydar Street kitchens to the offices, schools and industrial units across Truro and the wider Cornwall.
The full run, canopy through the concealed horizontal and vertical ductwork to the roof fan - the hidden sections a canopy-only clean leaves loaded, which matters in the tight stock around Boscawen Street and Lemon Street where the runs are long and awkward.
Yes. We clean the dry ductwork and air-handling in Truro offices, schools and public buildings, and the lint-heavy laundry ducts in the Cornwall hotels and care homes, alongside kitchen grease ducts.
Yes. The fan at the top of a Lemon Street 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.
Yes. We work overnight, early mornings and closing days for the Boscawen Street and Pydar Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
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 Lemon Street conversions where the run was boxed in with no hatches.
Local knowledge
From the early thirteenth century Newham handled the tin trade, and by the eighteenth century its quays carried smelting works, coal and gas supplies and a mile of warehousing served by the old Newham railway line that ran cargo the three miles to the main line until 1965. The riverside estate that replaced those yards now hides its 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 city, then hand over photographic before-and-after evidence of every run.
