Wisbech · 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 Wisbech, and certify it to the TR19 Grease standard your insurer expects.
Wisbech
Wisbech 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.
From Market Place to High Street and Union Street, 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.
Beyond the kitchens, we clean the dry ductwork and air-handling in offices, schools and public buildings, and the lint-heavy laundry ducts in hotels and care homes. High-output kitchens - the College of West Anglia, the North Cambridgeshire Hospital, the Horsefair Shopping Centre and the town hotels - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Wisbech insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard works in grease-film thickness, fixing the depth at which a run must be cleaned and re-tested. In the shared roof voids around Market Place and Union Street, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Wisbech run through existing and newly cut inspection hatches, strip it to bare metal, log grease-depth readings at fixed points before and after, and issue a TR19 Grease certificate with the post-clean depths recorded.
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 Wisbech hotels, care homes and gyms.
On the ground in Wisbech
We are in Wisbech's ductwork and plant every week. The proof is the jobs, not the stock photos.
A North Brink restaurant in Wisbech, working out of one of the Georgian merchant houses that line the Nene, had its extract threaded up through a listed staircase void to a cowl hidden behind a parapet. Grease had built where the run kinked around an old chimney breast, and the smell had started reaching the first-floor dining room. We could not cut hatches into the protected plasterwork, so we worked the run from the roof down and from the kitchen up, meeting in the middle with rods and a camera to prove the join was clean. The parapet cowl was lifted, degreased and reseated on fresh mastic. We left the staircase untouched and the historic frontage exactly as we found it - the grease came out, the fabric stayed in.
When it is due
Ductwork rarely warns you politely. In a busy Wisbech kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Market Place cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Wisbech insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying High 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 Wisbech 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 Union Street 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 Wisbech fire logbook.
Why it matters
Three duties push every Wisbech 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 Wisbech 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 Market Place 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 Wisbech 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. Food hygiene inspections by Fenland District 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 Market Place kitchen sits in a tighter band than a daytime High Street cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Wisbech run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a High Street cookline is back in service for the next shift.
Yes. The fan at the top of a Union Street 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 Market Place and High Street kitchens to the offices, schools and industrial units across Wisbech and the wider Cambridgeshire.
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 Union Street conversions where the run was boxed in with no hatches.
Yes. We clean the dry ductwork and air-handling in Wisbech offices, schools and public buildings, and the lint-heavy laundry ducts in the Cambridgeshire hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Market Place and High Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
