Shrewsbury · 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 Shrewsbury, and certify it to the TR19 Grease standard your insurer expects.
Shrewsbury
Shrewsbury rates thousands 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 Wyle Cop to Mardol and Abbey Foregate, 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 Shrewsbury offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - the Shrewsbury Colleges Group, the Royal Shrewsbury Hospital, the Croud Meadow 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 Shrewsbury 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 Wyle Cop and Abbey Foregate, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Shrewsbury 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 Shrewsbury hotels, care homes and gyms.
On the ground in Shrewsbury
We are in Shrewsbury's ductwork and plant every week. The proof is the jobs, not the stock photos.
A historic office block in Shrewsbury had heavy atmospheric dust, pollen and fine black particulate coating the internal faces of its supply-air ducts. We isolated the runs into manageable zones, ran motorised rotary power brushes through and vacuumed the debris out with a HEPA air mover, lifting the air quality across the office floors. We sourced a set of pleated synthetic filters for the on-site maintenance team.
When it is due
Ductwork rarely warns you politely. In a busy Shrewsbury kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Wyle Cop cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Shrewsbury insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Mardol 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 Shrewsbury 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 Abbey Foregate 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 Shrewsbury fire logbook.
Why it matters
Three duties push every Shrewsbury 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 Shrewsbury 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 Wyle Cop 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 Shrewsbury 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. When Shropshire 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 Wyle Cop kitchen sits in a tighter band than a daytime Mardol 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 Abbey Foregate conversions where the run was boxed in with no hatches.
Yes. We work overnight, early mornings and closing days for the Wyle Cop and Mardol kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes - from Wyle Cop and Mardol kitchens to the offices, schools and industrial units across Shrewsbury and the wider Shropshire.
Little, if it is planned. We survey the Shrewsbury run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Mardol cookline is back in service for the next shift.
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 Wyle Cop and Abbey Foregate where the runs are long and awkward.
Yes. The fan at the top of an Abbey Foregate 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.
