Warrington · 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 Warrington, and certify it to the TR19 Grease standard your insurer expects.
Warrington
Warrington rates around 1,800 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 Stockton Heath to Bridge Street and Palmyra Square, 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 Warrington offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - the University of Chester Warrington campus, Warrington Hospital, the Halliwell Jones Stadium and the town hotels - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Warrington insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard is written in film thickness: once grease reaches a set depth the run has to be cleaned and proven again. In the crowded roof voids off Stockton Heath and Palmyra Square, a wipe of the canopy and filters never reaches the ductwork behind them, where the grease that carries fire quietly gathers. We work the whole Warrington run through hatches already in place and others we cut, bring it back to bright metal, note grease depths at fixed stations before and after, and certify to TR19 Grease with the closing figures logged.
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 Warrington hotels, care homes and gyms.
On the ground in Warrington
We are in Warrington's ductwork and plant every week. The proof is the jobs, not the stock photos.
An industrial textile-processing factory in Warrington had huge amounts of coarse wool lint and synthetic fibre filling over 40% of the heavy overhead exhaust ducting. We ran high-powered vacuum extraction with pneumatic air whips to clear the long overhead runs, improving the dryer ventilation and cutting the energy cost and cycle times. The floor was on a light shift, so we cordoned our work area off safely.
When it is due
Ductwork rarely warns you politely. In a busy Warrington kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Stockton Heath cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Warrington insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Bridge Street 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 Warrington 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 Palmyra Square 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 Warrington fire logbook.
Why it matters
Three duties push every Warrington 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 Warrington 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 Stockton Heath 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 Warrington 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. Food hygiene inspections by Warrington Borough 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 Stockton Heath kitchen sits in a tighter band than a daytime Bridge Street cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Warrington run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Bridge Street cookline is back in service for the next shift.
Yes. We clean the dry ductwork and air-handling in Warrington offices, schools and public buildings, and the lint-heavy laundry ducts in the Cheshire hotels and care homes, alongside kitchen grease ducts.
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 Palmyra Square conversions where the run was boxed in with no hatches.
Yes. The fan at the top of a Palmyra Square 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 - from Stockton Heath and Bridge Street kitchens to the offices, schools and industrial units across Warrington and the wider Cheshire.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Stockton Heath operator's insurer and fire risk assessor expect.
