Bristol · 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 Bristol, and certify it to the TR19 Grease standard your insurer expects.
Bristol
Bristol rates around 4,470 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 Wapping Wharf to Whiteladies Road and Harbourside, 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 two universities, Southmead and the Bristol Royal Infirmary, Ashton Gate and the city hotels - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Bristol insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Grease is measured by thickness, and the standard sets the depth at which a system must be cleaned and re-tested. Around Wapping Wharf and Harbourside, where the concealed runs thread through mixed roof voids, a canopy-and-filter wipe leaves the ductwork itself - the long hidden sections where grease accumulates and a fire travels - untouched. We access the full Bristol run through existing and newly fitted inspection hatches, clean to bare metal, record before-and-after grease-depth readings at set points, and issue a TR19 Grease certificate with a post-clean depth record.
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 Bristol hotels, care homes and gyms.
On the ground in Bristol
We are in Bristol's ductwork and plant every week. The proof is the jobs, not the stock photos.
A residential care home in Bristol had us in for its laundry ducting - the commercial dryer exhaust lines were packed tight with flammable lint and fabric fibre. We vacuumed out the main dryer plenums, ran flexible push-rod brushes through the lines and checked the external discharge flap was opening properly. The dryers cycled faster afterwards, the fire risk was gone and the energy bill came down with it - and the kitchen staff kept us in tea while we worked round their laundry schedule.
When it is due
Ductwork rarely warns you politely. In a busy Bristol 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 Wapping Wharf line, grease crusting at the filter rims, or a Bristol 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 Whiteladies Road 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 Bristol 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 Harbourside 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 Bristol fire logbook.
Why it matters
Three duties push every Bristol 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 Bristol 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 Wapping Wharf 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. To a Bristol insurer a current TR19 Grease certificate is the proof the extract has been kept up. Let it lapse and a fire claim can be scaled back or declined outright - the kind of gap nobody wants to find with the kitchen already gutted.
Hygiene and environmental health. A food hygiene visit from Bristol City 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 Wapping Wharf kitchen sits in a tighter band than a daytime Whiteladies Road cafe. We measure the grease load and confirm your interval.
Yes. The fan at the top of a Harbourside 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.
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 Wapping Wharf and Harbourside where the runs are long and awkward.
Yes - from Wapping Wharf and Whiteladies Road kitchens to the offices, schools and industrial units across Bristol and the wider West of England.
Yes. We clean the dry ductwork and air-handling in Bristol offices, schools and public buildings, and the lint-heavy laundry ducts in the West of England hotels and care homes, alongside kitchen grease ducts.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Wapping Wharf operator's insurer and fire risk assessor expect.
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 Harbourside conversions where the run was boxed in with no hatches.
