Oswestry · 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 Oswestry, and certify it to the TR19 Grease standard your insurer expects.
Oswestry
Oswestry 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 Oswestry work out of tight, mixed premises - Bailey Street, Willow Street, Morda - 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.
Beyond the kitchens, we clean the dry ductwork and air-handling in offices, schools and public buildings, and the lint-heavy laundry ducts in hotels and care homes. High-output kitchens - hospital and college kitchens, hotel and pub kitchens and the busy market-town takeaways - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Oswestry 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 Bailey Street and Morda, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Oswestry 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 Oswestry hotels, care homes and gyms.
On the ground in Oswestry
We are in Oswestry's ductwork and plant every week. The proof is the jobs, not the stock photos.
Staff at a well-known Oswestry GP surgery had been complaining of dry eyes and stale air, and the supply ductwork behind it was coated in settled dust. I ran brushes and HEPA extraction through the ducting, then washed and refitted the supply grilles. The supply air was brought back to a clean standard, and the client was really pleased with how it turned out. I fitted the work into a quiet Monday to suit the office manager.
When it is due
Ductwork rarely warns you politely. In a busy Oswestry 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 Bailey Street line, grease crusting at the filter rims, or an Oswestry 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 Willow 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 Oswestry 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 Morda 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 Oswestry fire logbook.
Why it matters
Three duties push every Oswestry 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 Oswestry 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 Bailey 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 current TR19 Grease certificate is the evidence your Oswestry 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. When Shropshire 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 Bailey Street kitchen sits in a tighter band than a daytime Willow Street cafe. We measure the grease load and confirm your interval.
Yes. The fan at the top of a Morda 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. We clean the dry ductwork and air-handling in Oswestry offices, schools and public buildings, and the lint-heavy laundry ducts in the Shropshire hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Bailey Street and Willow 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 Oswestry run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Willow Street cookline is back in service for the next shift.
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 Morda conversions where the run was boxed in with no hatches.
Yes - from Bailey Street and Willow Street kitchens to the offices, schools and industrial units across Oswestry and the wider Shropshire.
Local knowledge
Along the banks of the River Morda a string of mills once ground corn and worked textiles, paper and animal products, their air heavy with dust drawn straight off the machinery. Modern premises hide that dust inside sealed ductwork instead, where grease and debris gather unseen until airflow fails or fire finds a path. We clean and inspect ventilation and extract ductwork across Oswestry and Morda, from the town-centre kitchens to the units on the industrial estates. Then we hand over photographic before-and-after evidence of every run.
