Prescot · 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 Prescot, and certify it to the TR19 Grease standard your insurer expects.
Prescot
Prescot 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 Prescot, from Eccleston Street through Kemble Street to Portico, 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.
It is not only kitchens: we also clean the dry supply and extract ductwork in Prescot offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - hospital kitchens, college refectories, pub and restaurant kitchens and the busy town-centre takeaways - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Prescot 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 Eccleston Street and Portico, 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 Prescot 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 Prescot hotels, care homes and gyms.
On the ground in Prescot
We are in Prescot's ductwork and plant every week. The proof is the jobs, not the stock photos.
A heavy blanket of fine grey dust had settled through the supply ducting serving the open-plan space at a popular Prescot community centre. I cleaned the main runs with air whips under negative pressure and renewed the tired pocket filters. The rooms felt fresher and the stale, dusty smell was gone, and I wrapped up with a tidy hand-over. The site's dog watched over us from a sunny windowsill throughout.
When it is due
Ductwork rarely warns you politely. In a busy Prescot kitchen these are the tells.
Watch for steam that hangs in the room, cooking smells creeping back over the tables, a canopy weeping onto an Eccleston Street line, grease crusting at the filter rims, or a Prescot 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 Kemble Street 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 Prescot 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 Portico 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 Prescot fire logbook.
Why it matters
Three duties push every Prescot 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 Prescot 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 an Eccleston Street 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 Prescot 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 Knowsley 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 Eccleston Street kitchen sits in a tighter band than a daytime Kemble Street cafe. We measure the grease load and confirm your interval.
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 Portico conversions where the run was boxed in with no hatches.
Yes. The fan at the top of a Portico 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.
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 Eccleston Street and Portico where the runs are long and awkward.
Yes - from Eccleston Street and Kemble Street kitchens to the offices, schools and industrial units across Prescot and the wider Merseyside.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence an Eccleston Street operator's insurer and fire risk assessor expect.
Yes. We work overnight, early mornings and closing days for the Eccleston Street and Kemble Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Local knowledge
For much of the twentieth century Prescot ran on cable. British Insulated Callender's Cables built a vast works in the town that was its primary industrial employer until it closed in the early 1990s, the ground later cleared and reborn as Cables Retail Park, named for the trade that once filled it. Where that work once packed open sheds with heat and fume, modern premises hide their 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 the town, then hand over photographic before-and-after evidence of every run.
