Huddersfield · 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 Huddersfield, and certify it to the TR19 Grease standard your insurer expects.
Huddersfield
Huddersfield rates around 3,700 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.
From Cross Church Street to Lindley and Lockwood, the town's cooklines vent through long hidden ducting that climbs to a roof fan. We clean it end to end to the TR19 Grease standard - not just the canopy, but the flat and rising sections where grease really collects.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Huddersfield schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - the University of Huddersfield, the Huddersfield Royal Infirmary, the Kirklees 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 Huddersfield insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard works in grease-film thickness, fixing the depth at which a run must be cleaned and re-tested. In the shared roof voids around Cross Church Street and Lockwood, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Huddersfield run through existing and newly cut inspection hatches, strip it to bare metal, log grease-depth readings at fixed points before and after, and issue a TR19 Grease certificate with the post-clean depths recorded.
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 Huddersfield hotels, care homes and gyms.
On the ground in Huddersfield
We are in Huddersfield's ductwork and plant every week. The proof is the jobs, not the stock photos.
A busy Asian-fusion restaurant in Huddersfield had greasy soot and congealed wok oil built up along the high-temperature canopy and the fan blades. We worked a heavy-duty alkaline gel in, hand-scraped the whole horizontal run and hot-pressure-washed the vertical roof stack. The extraction performance roughly doubled, clearing the smoky grease off the heavy wok line - and the kitchen staff had left it spotless so we could start straight away.
When it is due
Ductwork rarely warns you politely. In a busy Huddersfield kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Cross Church Street line, a rim of grease at the filters, or a Huddersfield insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Lindley 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 Huddersfield 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 Lockwood 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 Huddersfield fire logbook.
Why it matters
Three duties push every Huddersfield 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 Huddersfield 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 Cross Church 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. A live TR19 Grease certificate is what a Huddersfield insurer treats as evidence the system is maintained. Miss it and a fire claim may be reduced or refused - an expensive surprise once the damage is done.
Hygiene and environmental health. When Kirklees 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 Cross Church Street kitchen sits in a tighter band than a daytime Lindley cafe. We measure the grease load and confirm your interval.
Yes. We clean the dry ductwork and air-handling in Huddersfield offices, schools and public buildings, and the lint-heavy laundry ducts in the West Yorkshire hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Cross Church Street and Lindley 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 Huddersfield run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Lindley cookline is back in service for the next shift.
Yes - from Cross Church Street and Lindley kitchens to the offices, schools and industrial units across Huddersfield and the wider West Yorkshire.
Yes. The fan at the top of a Lockwood 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.
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 Lockwood conversions where the run was boxed in with no hatches.
