Dewsbury · 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 Dewsbury, and certify it to the TR19 Grease standard your insurer expects.
Dewsbury
Dewsbury 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 Place, Northgate, Princess of Wales Precinct - 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.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Dewsbury schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - Kirklees College, Dewsbury and District Hospital, the FLAIR Stadium and the town hotels - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Dewsbury 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 Place and Princess of Wales Precinct, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Dewsbury 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 Dewsbury hotels, care homes and gyms.
On the ground in Dewsbury
We are in Dewsbury's ductwork and plant every week. The proof is the jobs, not the stock photos.
A first-floor snooker club above Dewsbury Market had its ceiling-void extract running warm and slack, the flexible drops perished and shedding lining down over the baize. We cut out the failed flexible, replaced it with rigid spiral, sealed the branch takeoffs where the old tape had let go, and re-tensioned the roof-fan belt that had been slipping under load. Airflow lifted back to the design figure across the tables, the shed lining stopped drifting onto the cushions, and the stale-smoke smell that had soaked the upstairs room went with it. We left the club a marked-up layout of the new access points, and flagged the neighbouring first-floor bar off Foundry Street whose shared riser was carrying the same perished ducting toward one roof cowl.
When it is due
Ductwork rarely warns you politely. In a busy Dewsbury kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Market Place line, a rim of grease at the filters, or a Dewsbury insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Northgate 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 Dewsbury 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 Princess of Wales Precinct 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 Dewsbury fire logbook.
Why it matters
Three duties push every Dewsbury 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 Dewsbury 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 Place 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 Dewsbury 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. Kirklees 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 Market Place kitchen sits in a tighter band than a daytime Northgate cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Dewsbury run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Northgate 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 Market Place and Princess of Wales Precinct where the runs are long and awkward.
Yes. The fan at the top of a Princess of Wales Precinct 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 - from Market Place and Northgate kitchens to the offices, schools and industrial units across Dewsbury and the wider West Yorkshire.
Yes. We work overnight, early mornings and closing days for the Market Place and Northgate kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Market Place operator's insurer and fire risk assessor expect.
