Chapeltown · 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 Chapeltown, and certify it to the TR19 Grease standard your insurer expects.
Chapeltown
Chapeltown 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 - Mortomley Lane, Burncross Road, Thorncliffe Road - 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.
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 - pub and restaurant kitchens, takeaways, cafes and the care-home and school kitchens - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Chapeltown 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 Mortomley Lane and Thorncliffe Road, 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 Chapeltown 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 Chapeltown hotels, care homes and gyms.
On the ground in Chapeltown
We are in Chapeltown's ductwork and plant every week. The proof is the jobs, not the stock photos.
A busy Chapeltown fish and chip shop had grease pooling in the low points of its kitchen extract run, sitting over the hot plates. I scraped and degreased the canopy extract duct until the steel was clean, and gave the griddle a going-over while I was in there. The finished run met TR19 with the grease and carbon gone, and I put together certification for the client's file. The head chef got a short set of images to keep with their compliance records.
When it is due
Ductwork rarely warns you politely. In a busy Chapeltown kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Mortomley Lane line, a rim of grease at the filters, or a Chapeltown insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Burncross Road 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 Chapeltown 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 Thorncliffe Road 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 Chapeltown fire logbook.
Why it matters
Three duties push every Chapeltown 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 Chapeltown 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 Mortomley Lane 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 Chapeltown 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 Sheffield City 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 Mortomley Lane kitchen sits in a tighter band than a daytime Burncross Road cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Chapeltown run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Burncross Road cookline is back in service for the next shift.
Yes. We clean the dry ductwork and air-handling in Chapeltown offices, schools and public buildings, and the lint-heavy laundry ducts in the South Yorkshire hotels and care homes, alongside kitchen grease ducts.
Yes - from Mortomley Lane and Burncross Road kitchens to the offices, schools and industrial units across Chapeltown 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 Thorncliffe Road conversions where the run was boxed in with no hatches.
Yes. We work overnight, early mornings and closing days for the Mortomley Lane and Burncross Road 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 Mortomley Lane operator's insurer and fire risk assessor expect.
Local knowledge
The Thorncliffe works did more than cast iron; from the 1890s Newton Chambers distilled coal tar into the Izal disinfectant and abrasive medicated toilet paper that filled school and public lavatories across Britain, its furnaces and by-product plants thickening the valley air with smoke and fume. Modern premises hide their dust and grease inside sealed ductwork instead, where debris builds unseen until airflow fails or fire finds a path. We clean and inspect ventilation and extract ductwork across Chapeltown and High Green, then hand over photographic before-and-after evidence of every run.
