Doncaster · 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 Doncaster, and certify it to the TR19 Grease standard your insurer expects.
Doncaster
Doncaster rates around 2,700 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 Doncaster work out of tight, mixed premises - Copley Road, Silver Street, Cleveland Street - 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 Doncaster schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - University Centre Doncaster, Doncaster Royal Infirmary, the Eco-Power Stadium and Doncaster Racecourse - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Doncaster 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 Copley Road and Cleveland Street, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Doncaster 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 Doncaster hotels, care homes and gyms.
On the ground in Doncaster
We are in Doncaster's ductwork and plant every week. The proof is the jobs, not the stock photos.
A council care home in Doncaster had textile lint clogging more than 40 percent of the internal diameter of its tumble-dryer exhaust ductwork - both a drying problem and a fire risk over a residential floor. We ran high-volume vacuum extraction and flexible manual rods along the horizontal runs and swept them clear to the outside. The dryer cycles came back and the ignition risk was gone. We kept the noise down near the residents' lounge by clearing it with the ward manager first.
When it is due
Ductwork rarely warns you politely. In a busy Doncaster 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 Copley Road line, grease crusting at the filter rims, or a Doncaster 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 Silver 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 Doncaster 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 Cleveland Street 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 Doncaster fire logbook.
Why it matters
Three duties push every Doncaster 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 Doncaster 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 Copley Road 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 Doncaster 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. Food hygiene inspections by City of Doncaster Council take in the condition of the building, ventilation included, so a grease-laden system can cost you on the rating an Environmental Health Officer awards - never mind the smell and the dropping extraction your kitchen team works under.
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 Copley Road kitchen sits in a tighter band than a daytime Silver 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 Copley Road operator's insurer and fire risk assessor expect.
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 Copley Road and Cleveland Street where the runs are long and awkward.
Yes - from Copley Road and Silver Street kitchens to the offices, schools and industrial units across Doncaster and the wider South 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 Cleveland Street conversions where the run was boxed in with no hatches.
Yes. We work overnight, early mornings and closing days for the Copley Road and Silver Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Little, if it is planned. We survey the Doncaster run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Silver Street cookline is back in service for the next shift.
