Corby · 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 Corby, and certify it to the TR19 Grease standard your insurer expects.
Corby
Corby 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 Corby work out of tight, mixed premises - George Street, Willow Place, Studfall Avenue - 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 Corby schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - the local college, the town's community hospital, Steel Park 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 Corby insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard is written in film thickness: once grease reaches a set depth the run has to be cleaned and proven again. In the crowded roof voids off George Street and Studfall Avenue, a wipe of the canopy and filters never reaches the ductwork behind them, where the grease that carries fire quietly gathers. We work the whole Corby run through hatches already in place and others we cut, bring it back to bright metal, note grease depths at fixed stations before and after, and certify to TR19 Grease with the closing figures logged.
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 Corby hotels, care homes and gyms.
On the ground in Corby
We are in Corby's ductwork and plant every week. The proof is the jobs, not the stock photos.
A distribution-park canteen in Corby had grease along the extract runs and warehouse dust drawn into the supply grilles from the loading hall. We scraped the extract lengths back to metal, ran a degreaser through the sealed sections and washed the grilles down, restoring the extraction and the incoming air. The clean was worked around the canteen's shift meal breaks so the golden-triangle crews kept their service.
When it is due
Ductwork rarely warns you politely. In a busy Corby kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a George Street cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Corby insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Willow Place kitchen needs it far more often than a daytime cafe - and your certificate states the interval, so the next clean is never a guess.
How it runs
Inspect the full Corby 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 Studfall Avenue 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 Corby fire logbook.
Why it matters
Three duties push every Corby 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 Corby 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 George 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 Corby 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 North Northamptonshire 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 George Street kitchen sits in a tighter band than a daytime Willow Place cafe. We measure the grease load and confirm your interval.
Yes. We work overnight, early mornings and closing days for the George Street and Willow Place 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 George Street operator's insurer and fire risk assessor expect.
Yes - from George Street and Willow Place kitchens to the offices, schools and industrial units across Corby and the wider Northamptonshire.
Yes. We clean the dry ductwork and air-handling in Corby offices, schools and public buildings, and the lint-heavy laundry ducts in the Northamptonshire hotels and care homes, alongside kitchen grease ducts.
Yes. The fan at the top of a Studfall Avenue 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.
Little, if it is planned. We survey the Corby run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Willow Place cookline is back in service for the next shift.
