Bath · 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 Bath, and certify it to the TR19 Grease standard your insurer expects.
Bath
Bath rates around 1,850 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.
The city's kitchens sit in tight, mixed stock - Milsom Street, George Street, Corridor - with long concealed duct runs up to roof fans. We clean the full run to the TR19 Grease standard, canopy to fan, including the horizontal and vertical sections a canopy-only clean leaves coated.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Bath schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - the University of Bath, the Royal United Hospital, the Recreation Ground and the city hotels - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Bath 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 Milsom Street and Corridor, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Bath 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 Bath hotels, care homes and gyms.
On the ground in Bath
We are in Bath's ductwork and plant every week. The proof is the jobs, not the stock photos.
A boutique hotel kitchen in Bath had baked-on grease and carbonised fat behind the multi-burner ranges, cutting the extraction. We fitted two new fire-rated access doors along the horizontal runs, hand-scraped the heavy crusts off and wiped the lines clean, roughly doubling the extraction and meeting the heritage-building insurance codes. The cellar layout meant routing long vacuum hoses through a narrow stone window.
When it is due
Ductwork rarely warns you politely. In a busy Bath kitchen these are the tells.
Watch for steam that hangs in the room, cooking smells creeping back over the tables, a canopy weeping onto a Milsom Street line, grease crusting at the filter rims, or a Bath 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 George 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 Bath 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 Corridor 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 Bath fire logbook.
Why it matters
Three duties push every Bath 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 Bath 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 Milsom 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 current TR19 Grease certificate is the evidence your Bath 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 Bath and North East Somerset 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 Milsom Street kitchen sits in a tighter band than a daytime George Street cafe. We measure the grease load and confirm your interval.
Yes. We clean the dry ductwork and air-handling in Bath offices, schools and public buildings, and the lint-heavy laundry ducts in the Somerset hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Milsom Street and George Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Little, if it is planned. We survey the Bath run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a George Street cookline is back in service for the next shift.
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 Corridor conversions where the run was boxed in with no hatches.
Yes. The fan at the top of a Corridor 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.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Milsom Street operator's insurer and fire risk assessor expect.
