Ossett · 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 Ossett, and certify it to the TR19 Grease standard your insurer expects.
Ossett
Ossett 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.
Kitchens across Ossett work out of tight, mixed premises - Dale Street, Wesley Street, Chickenley - 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.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Ossett schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - care-home kitchens, pub and restaurant kitchens, bakeries and the busy market-town takeaways - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Ossett 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 Dale Street and Chickenley, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Ossett 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 Ossett hotels, care homes and gyms.
On the ground in Ossett
We are in Ossett's ductwork and plant every week. The proof is the jobs, not the stock photos.
Behind the grilles at a high-street Ossett office suite, the supply ductwork was thick with atmospheric dust, giving stale, warm air through the occupied floors. I power-brushed the fresh-air ducting under HEPA negative pressure and cleared the ceiling diffusers. The supply air was restored to a clean standard, and the client booked us back in there and then. The practice manager kept the tea coming through the morning.
When it is due
Ductwork rarely warns you politely. In a busy Ossett kitchen these are the tells.
A canopy dripping onto a Dale Street cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or an Ossett insurer or fire risk assessor wanting a TR19 certificate you have not got. How often it needs doing follows how hard you cook - a fast-frying Wesley Street kitchen far more than a daytime cafe - and the certificate names the interval, so the next visit is booked, not guessed.
How it runs
Inspect the full Ossett 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 Chickenley 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 Ossett fire logbook.
Why it matters
Three duties push every Ossett 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 an Ossett 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 Dale 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 an Ossett 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. Wakefield 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 Dale Street kitchen sits in a tighter band than a daytime Wesley Street cafe. We measure the grease load and confirm your interval.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Dale Street operator's insurer and fire risk assessor expect.
Little, if it is planned. We survey the Ossett run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Wesley Street cookline is back in service for the next shift.
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 Dale Street and Chickenley where the runs are long and awkward.
Yes. We clean the dry ductwork and air-handling in Ossett offices, schools and public buildings, and the lint-heavy laundry ducts in the West Yorkshire hotels and care homes, alongside kitchen grease ducts.
Yes - from Dale Street and Wesley Street kitchens to the offices, schools and industrial units across Ossett and the wider West Yorkshire.
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 Chickenley conversions where the run was boxed in with no hatches.
Local knowledge
At its peak Ossett worked more than forty mills, and with neighbouring Dewsbury it became the world centre of the shoddy and mungo trade, recovering wool from rags brought in by the wagonload and grinding it in air heavy with fibre and grit. Modern premises hide their dust inside sealed ductwork instead, where grease and debris build unseen until airflow fails or fire finds a path. We clean and inspect ventilation and extract ductwork across the town, from the converted mill units at Healey New Mills to shops off Bank Street and Chickenley. Every job is handed over with photographic before-and-after evidence of each run.
