Slough · 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 Slough, and certify it to the TR19 Grease standard your insurer expects.
Slough
Slough rates around 950 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 Farnham Road to William Street and High Street, 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.
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 - the Slough Trading Estate, Wexham Park Hospital, Arbour Park and the business hotels - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Slough 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 Farnham Road and High Street, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Slough 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 Slough hotels, care homes and gyms.
On the ground in Slough
We are in Slough's ductwork and plant every week. The proof is the jobs, not the stock photos.
An international data-centre building in Slough had fine carbon dust and airborne soil settling in the backup-generator room supply ducts. We ran HEPA-filtered negative-air movers and delicate microfibre dusting kits through the rectangular galvanised lines, keeping the supply air particulate-free to protect the server racks. It was full anti-static coveralls and non-marking overshoes throughout the high-security facility.
When it is due
Ductwork rarely warns you politely. In a busy Slough kitchen these are the tells.
A canopy dripping onto a Farnham Road cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Slough 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 William 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 Slough 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 High Street 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 Slough fire logbook.
Why it matters
Three duties push every Slough 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 Slough 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 Farnham 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. To a Slough 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. Slough Borough 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 Farnham Road kitchen sits in a tighter band than a daytime William Street cafe. We measure the grease load and confirm your interval.
Yes. We work overnight, early mornings and closing days for the Farnham Road and William Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes. We clean the dry ductwork and air-handling in Slough offices, schools and public buildings, and the lint-heavy laundry ducts in the Berkshire hotels and care homes, alongside kitchen grease ducts.
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 Farnham Road and High Street where the runs are long and awkward.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Farnham Road 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 High Street conversions where the run was boxed in with no hatches.
Little, if it is planned. We survey the Slough run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a William Street cookline is back in service for the next shift.
