Nelson · 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 Nelson, and certify it to the TR19 Grease standard your insurer expects.
Nelson
Nelson 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.
Right across Nelson, from Scotland Road through Manchester Road to Marsden, cooklines share tight roof space and vent through concealed ducting few operators ever see inside. We clean that entire path to the TR19 Grease standard, canopy through to fan, taking in the level pulls and the risers where grease settles thickest and a fire would run.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Nelson schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - hospital kitchens, college refectories, pub and takeaway kitchens and the busy town-centre cafes - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Nelson insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Because the standard is written around film thickness, it sets the depth that triggers a clean and re-test. In the mixed roof spaces around Scotland Road and Marsden, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Nelson run through existing hatches and new ones we cut, clean back to bright metal, take before-and-after grease-depth figures at set points, and certify it to TR19 Grease with those depths on the 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 Nelson hotels, care homes and gyms.
On the ground in Nelson
We are in Nelson's ductwork and plant every week. The proof is the jobs, not the stock photos.
A traditional leisure centre in Nelson had the extract grilles in its changing rooms clogged with fine dust and pulling next to nothing. We removed and washed the grilles, brushed out the branch ducting and cleaned the fan impeller. The ground-floor washrooms cleared of stale air with extraction back to a proper rate, the difference obvious straight away. We timed the job for the school holidays while the building was quiet.
When it is due
Ductwork rarely warns you politely. In a busy Nelson kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Scotland Road cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Nelson insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Manchester Road 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 Nelson 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 Marsden 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 Nelson fire logbook.
Why it matters
Three duties push every Nelson 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 Nelson 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 Scotland 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 current TR19 Grease certificate is the evidence your Nelson 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. Pendle 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 Scotland Road kitchen sits in a tighter band than a daytime Manchester Road cafe. We measure the grease load and confirm your interval.
Yes. We work overnight, early mornings and closing days for the Scotland Road and Manchester Road 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 Nelson run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Manchester Road 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 Scotland Road operator's insurer and fire risk assessor expect.
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 Scotland Road and Marsden where the runs are long and awkward.
Yes. The fan at the top of a Marsden 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 Nelson offices, schools and public buildings, and the lint-heavy laundry ducts in the Lancashire hotels and care homes, alongside kitchen grease ducts.
Local knowledge
Lomeshaye began as a water-powered worsted spinning mill built by the wool merchant Richard Ecroyd around 1780, one of the oldest industrial sites in the town, and Nelson grew around such mills until weaving sheds and their lint-laden air filled the valley. Modern premises hide their dust inside sealed ductwork instead, where grease and debris build 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. What the eye cannot see, the camera and the airflow reading will.
