Horwich · 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 Horwich, and certify it to the TR19 Grease standard your insurer expects.
Horwich
Horwich 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 - Winter Hey Lane, Lee Lane, Long Lane - 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.
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 - pub and hotel kitchens, care-home kitchens, retail-park chain restaurants and the busy town-centre takeaways - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Horwich 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 Winter Hey Lane and Long 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 Horwich 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 Horwich hotels, care homes and gyms.
On the ground in Horwich
We are in Horwich's ductwork and plant every week. The proof is the jobs, not the stock photos.
Damp, matted lint had gathered at the low point of the flexible dryer ducting in a small Horwich care home, and it was tripping the dryers' overheat cut-outs. We brushed and vacuumed the run from end to end and confirmed the wall termination was opening fully again. That cleared the fire risk and left the utility room feeling cooler and drier straight away, with everything handed back in order. We ran a single overnight shift so the laundry could open as usual.
When it is due
Ductwork rarely warns you politely. In a busy Horwich 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 Winter Hey Lane line, grease crusting at the filter rims, or a Horwich 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 Lee Lane 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 Horwich 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 Long 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 Horwich fire logbook.
Why it matters
Three duties push every Horwich 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 Horwich 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 Winter Hey 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 live TR19 Grease certificate is what a Horwich 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. When Bolton Metropolitan Borough 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 Winter Hey Lane kitchen sits in a tighter band than a daytime Lee Lane cafe. We measure the grease load and confirm your interval.
Yes. We clean the dry ductwork and air-handling in Horwich offices, schools and public buildings, and the lint-heavy laundry ducts in the Greater Manchester hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Winter Hey Lane and Lee Lane kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes. The fan at the top of a Long 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.
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 Long Lane conversions where the run was boxed in with no hatches.
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 Winter Hey Lane and Long Lane where the runs are long and awkward.
Yes - from Winter Hey Lane and Lee Lane kitchens to the offices, schools and industrial units across Horwich and the wider Greater Manchester.
Local knowledge
Thomas Ridgway and Sons opened the Wallsuches Bleach Works above Horwich in 1777, one of the first anywhere to bleach cloth with chlorine rather than sunlight, and it stayed among the town's main industries until 1933. Its long sheds ran thick with chemical vapour and the cotton lint that hung in the air its workers breathed. Modern premises hide that dust and grease inside sealed ductwork instead, where it builds unseen until airflow fails or fire finds a path. We clean and inspect ventilation and extract ductwork across Horwich, then hand over photographic before-and-after evidence of every run.
