Hounslow · 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 Hounslow, and certify it to the TR19 Grease standard your insurer expects.
Hounslow
Hounslow rates around 2,200 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.
Kitchens across Hounslow work out of tight, mixed premises - Staines Road, High Street, Treaty Centre - their extract snaking through concealed voids to roof-mounted fans. We take the whole run to the TR19 Grease standard, hood to fan, reaching the horizontal legs and vertical risers a canopy wipe never touches.
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 - West Thames College, West Middlesex University Hospital, the Gtech Community Stadium and the airport hotels - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Hounslow 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 Staines Road and Treaty Centre, 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 Hounslow 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 Hounslow hotels, care homes and gyms.
On the ground in Hounslow
We are in Hounslow's ductwork and plant every week. The proof is the jobs, not the stock photos.
A logistics-hub office near Hounslow had grey carpet fibre and ambient dust blocking the inline extract fan scrolls, leaving the washrooms with poor airflow. We took the ceiling grilles down for a deep clean, brushed the internal duct lines out and cleared the fan impellers, bringing the extraction back to the building-regulation rate. We found an old maintenance manual left inside the air handling unit filter section and handed it back to the site team.
When it is due
Ductwork rarely warns you politely. In a busy Hounslow kitchen these are the tells.
A canopy dripping onto a Staines Road cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Hounslow insurer or fire risk assessor wanting a TR19 certificate you have not got. How often it needs doing follows how hard you cook - a fast-frying High Street kitchen far more than a daytime cafe - and the certificate names the interval, so the next visit is booked, not guessed.
How it runs
Inspect the full Hounslow 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 Treaty Centre 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 Hounslow fire logbook.
Why it matters
Three duties push every Hounslow 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 Hounslow 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 Staines Road 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. Your Hounslow insurer expects a current TR19 Grease certificate as proof the duct is clean. Without one, a fire claim can be cut back or turned down altogether - a costly thing to find only after a fire.
Hygiene and environmental health. Hounslow Council food hygiene inspections assess the physical condition of premises, ventilation included. A grease-clogged system can count against the rating an Environmental Health Officer awards, quite apart from the smell and the falling extract performance your staff have to work in.
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 Staines Road kitchen sits in a tighter band than a daytime High Street cafe. We measure the grease load and confirm your interval.
Yes. We work overnight, early mornings and closing days for the Staines Road and High Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes. The fan at the top of a Treaty Centre 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 Staines Road and Treaty Centre where the runs are long and awkward.
Yes. We clean the dry ductwork and air-handling in Hounslow offices, schools and public buildings, and the lint-heavy laundry ducts in the Greater London hotels and care homes, alongside kitchen grease ducts.
Yes - from Staines Road and High Street kitchens to the offices, schools and industrial units across Hounslow and the wider Greater London.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Staines Road operator's insurer and fire risk assessor expect.
