Trowbridge · 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 Trowbridge, and certify it to the TR19 Grease standard your insurer expects.
Trowbridge
Trowbridge 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 Trowbridge, from Fore Street through Castle Street to Wicker Hill, 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.
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 - Wiltshire College, the Trowbridge Community Hospital, the Shires 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 Trowbridge 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 Fore Street and Wicker Hill, 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 Trowbridge 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 Trowbridge hotels, care homes and gyms.
On the ground in Trowbridge
We are in Trowbridge's ductwork and plant every week. The proof is the jobs, not the stock photos.
A Fore Street restaurant in Trowbridge had a heavy grease film through the horizontal extract and up the riser above a busy cook line. We fitted new access panels, hand-scraped the accessible lengths and ran an enzyme degreaser through the sealed sections, returning the ductwork to clean metal for the fire and insurance standard. It was worked overnight so the county-town trade lost no covers.
When it is due
Ductwork rarely warns you politely. In a busy Trowbridge kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Fore Street line, a rim of grease at the filters, or a Trowbridge insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Castle Street kitchen needs it far more often than a quiet cafe - and your certificate sets the date, so nothing is left to chance.
How it runs
Inspect the full Trowbridge 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 Wicker Hill conversions - and protect the kitchen.

Why it matters
Three duties push every Trowbridge 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 Trowbridge 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 Fore 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 Trowbridge 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. A food hygiene visit from Wiltshire Council weighs the physical state of the premises, ventilation counted within it. A grease-blocked extract can pull down the rating an Environmental Health Officer sets, quite apart from the stale smell and the tired airflow your staff work beneath all shift.
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 Fore Street kitchen sits in a tighter band than a daytime Castle Street cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Trowbridge run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Castle Street 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 Fore Street and Wicker Hill where the runs are long and awkward.
Yes. The fan at the top of a Wicker Hill 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 Fore Street and Castle Street kitchens to the offices, schools and industrial units across Trowbridge and the wider Wiltshire.
Yes. We work overnight, early mornings and closing days for the Fore Street and Castle Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
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 Wicker Hill conversions where the run was boxed in with no hatches.
