Hessle · 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 Hessle, and certify it to the TR19 Grease standard your insurer expects.
Hessle
Hessle 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 Hessle work out of tight, mixed premises - Prestongate, Southgate, First Lane - 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.
The same crews clean dry ventilation and air-handling ductwork in offices, schools and civic buildings, plus the combustible lint runs behind hotel and care-home dryers. High-turnover sites - care-home kitchens, pub and restaurant kitchens, cafes and the busy town-centre takeaways - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Hessle insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Grease is measured by thickness, and the standard sets the depth at which a system must be cleaned and re-tested. Around Prestongate and First Lane, where the concealed runs thread through mixed roof voids, a canopy-and-filter wipe leaves the ductwork itself - the long hidden sections where grease accumulates and a fire travels - untouched. We access the full Hessle run through existing and newly fitted inspection hatches, clean to bare metal, record before-and-after grease-depth readings at set points, and issue a TR19 Grease certificate with a post-clean depth 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 Hessle hotels, care homes and gyms.
On the ground in Hessle
We are in Hessle's ductwork and plant every week. The proof is the jobs, not the stock photos.
Grey dust had clogged the extract grilles in the public washrooms at a family-run Hessle leisure centre, and they were pulling next to nothing. I cleared the ceiling grilles, brushed out the flexible branches and cleaned the roof extract fan blades. The changing rooms lost their stale air with extraction back to a proper rate, and the client booked us back in there and then. The caretaker took a short photo report for their audit file.
When it is due
Ductwork rarely warns you politely. In a busy Hessle kitchen these are the tells.
A canopy dripping onto a Prestongate cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Hessle insurer or fire risk assessor wanting a TR19 certificate you have not got. How often it needs doing follows how hard you cook - a fast-frying Southgate kitchen far more than a daytime cafe - and the certificate names the interval, so the next visit is booked, not guessed.
How it runs
Inspect the full Hessle 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 First Lane 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 Hessle fire logbook.
Why it matters
Three duties push every Hessle 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 Hessle 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 Prestongate 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. To a Hessle insurer a current TR19 Grease certificate is the proof the extract has been kept up. Let it lapse and a fire claim can be scaled back or declined outright - the kind of gap nobody wants to find with the kitchen already gutted.
Hygiene and environmental health. Food hygiene inspections by East Riding of Yorkshire Council take in the condition of the building, ventilation included, so a grease-laden system can cost you on the rating an Environmental Health Officer awards - never mind the smell and the dropping extraction your kitchen team works under.
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 Prestongate kitchen sits in a tighter band than a daytime Southgate cafe. We measure the grease load and confirm your interval.
Yes. We work overnight, early mornings and closing days for the Prestongate and Southgate kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
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 First Lane conversions where the run was boxed in with no hatches.
Yes. The fan at the top of a First Lane 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 Hessle run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Southgate cookline is back in service for the next shift.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Prestongate operator's insurer and fire risk assessor expect.
Yes - from Prestongate and Southgate kitchens to the offices, schools and industrial units across Hessle and the wider East Riding of Yorkshire.
Local knowledge
Chalk was quarried at Hessle for centuries, and the whiting mill above the foreshore, a Smeaton design raised around 1810, ground crushed chalk into the fine white powder that went into paint, putty and later rubber and plastics, its air thick with pale dust. 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 the town, then hand over photographic before-and-after evidence of every run.
