Rochdale · 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 Rochdale, and certify it to the TR19 Grease standard your insurer expects.
Rochdale
Rochdale rates around 1,850 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 Milkstone Road to Yorkshire Street and Middleton, 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.
It is not only kitchens: we also clean the dry supply and extract ductwork in Rochdale offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - Hopwood Hall College, Rochdale Infirmary, the Crown Oil Arena and the borough hotels - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Rochdale 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 Milkstone Road and Middleton, 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 Rochdale 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 Rochdale hotels, care homes and gyms.
On the ground in Rochdale
We are in Rochdale's ductwork and plant every week. The proof is the jobs, not the stock photos.
A primary school in Rochdale had atmospheric dust, lint and paper-towel fibre coating the inside of its washroom extract branches, and the rooms smelled stale and damp. We ran negative-air machines with air whips to knock the dust loose and capture it out of the rigid spiral pipe, getting proper ventilation back across the washrooms. All of it was done over the winter shutdown with the classrooms empty.
When it is due
Ductwork rarely warns you politely. In a busy Rochdale kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Milkstone Road line, a rim of grease at the filters, or a Rochdale insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Yorkshire Street 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 Rochdale 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 Middleton 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 Rochdale fire logbook.
Why it matters
Three duties push every Rochdale 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 Rochdale 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 Milkstone Road 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 Rochdale 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. Rochdale Borough Council food hygiene inspections assess the physical condition of premises, ventilation included. A grease-clogged system can count against the rating an Environmental Health Officer awards, quite apart from the smell and the falling extract performance your staff have to work in.
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 Milkstone Road kitchen sits in a tighter band than a daytime Yorkshire Street cafe. We measure the grease load and confirm your interval.
Yes. We work overnight, early mornings and closing days for the Milkstone Road and Yorkshire Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes. We clean the dry ductwork and air-handling in Rochdale offices, schools and public buildings, and the lint-heavy laundry ducts in the Greater Manchester hotels and care homes, alongside kitchen grease ducts.
Yes. The fan at the top of a Middleton 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 Middleton conversions where the run was boxed in with no hatches.
Little, if it is planned. We survey the Rochdale run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Yorkshire Street cookline is back in service for the next shift.
The full run, canopy through the concealed horizontal and vertical ductwork to the roof fan - the hidden sections a canopy-only clean leaves loaded, which matters in the tight stock around Milkstone Road and Middleton where the runs are long and awkward.
