Ruislip · 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 Ruislip, and certify it to the TR19 Grease standard your insurer expects.
Ruislip
Ruislip 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 Ruislip, from High Street through Victoria Road to Eastcote, 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.
The same crews clean dry ventilation and air-handling ductwork in offices, schools and civic buildings, plus the combustible lint runs behind hotel and care-home dryers. High-turnover sites - pub and hotel kitchens, high-street takeaways, cafes and the institutional canteens - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Ruislip insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Because the standard is written around film thickness, it sets the depth that triggers a clean and re-test. In the mixed roof spaces around High Street and Eastcote, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Ruislip run through existing hatches and new ones we cut, clean back to bright metal, take before-and-after grease-depth figures at set points, and certify it to TR19 Grease with those depths on the 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 Ruislip hotels, care homes and gyms.
On the ground in Ruislip
We are in Ruislip's ductwork and plant every week. The proof is the jobs, not the stock photos.
A privately owned office suite in Ruislip had dust and debris built up in the branch ducts feeding the open-plan space, leaving the air barely moving. We worked through the supply ductwork with brushes and HEPA extraction, then cleaned and refitted the fan coil unit. The air through the building felt noticeably fresher and the dust complaints stopped, with everything back to normal by opening. The practice manager booked a regular annual visit on the spot.
When it is due
Ductwork rarely warns you politely. In a busy Ruislip 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 High Street line, grease crusting at the filter rims, or a Ruislip 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 Victoria 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 Ruislip 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 Eastcote 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 Ruislip fire logbook.
Why it matters
Three duties push every Ruislip 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 Ruislip 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 High 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 Ruislip 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. London Borough of Hillingdon 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 High Street kitchen sits in a tighter band than a daytime Victoria Road cafe. We measure the grease load and confirm your interval.
Yes. We clean the dry ductwork and air-handling in Ruislip offices, schools and public buildings, and the lint-heavy laundry ducts in the Greater London 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 High Street 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 Eastcote conversions where the run was boxed in with no hatches.
Yes. The fan at the top of an Eastcote 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. We work overnight, early mornings and closing days for the High Street and Victoria Road kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes - from High Street and Victoria Road kitchens to the offices, schools and industrial units across Ruislip and the wider Greater London.
Local knowledge
Ruislip Lido began life as a reservoir, opened in December 1811 to feed water into the Grand Junction Canal, the work of the engineer John Rennie before the flooded ground silted and the scheme was abandoned by 1851. That industrial water infrastructure gave way to a lido in 1933, and the town's working buildings now hide their air inside sealed ductwork instead of open channels, where grease and debris build unseen until airflow fails or fire finds a path. We clean and inspect ventilation and extract ductwork across the town, then hand over photographic before-and-after evidence of every run.
