Chatham · 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 Chatham, and certify it to the TR19 Grease standard your insurer expects.
Chatham
Chatham rates around 2,000 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 Chatham work out of tight, mixed premises - Chatham High Street, Military Road, Pentagon - 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 - the Universities at Medway, Medway Maritime Hospital, the Historic Dockyard and Priestfield Stadium - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Chatham 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 Chatham High Street and Pentagon, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Chatham 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 Chatham hotels, care homes and gyms.
On the ground in Chatham
We are in Chatham's ductwork and plant every week. The proof is the jobs, not the stock photos.
A naval dockyard office in Chatham had centuries-old dust, mortar debris and cobwebs built up inside its supply-air channels. We ran manual push-rod brushes and high-filtration HEPA vacuums gently through the old galvanised trunking, verifying the supply air clear for the staff. It was a Grade II listed building with restricted access, so long hoses had to be routed through a low ceiling hatch.
When it is due
Ductwork rarely warns you politely. In a busy Chatham 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 Chatham High Street line, grease crusting at the filter rims, or a Chatham 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 Military 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 Chatham 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 Pentagon 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 Chatham fire logbook.
Why it matters
Three duties push every Chatham 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 Chatham 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 Chatham 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. To a Chatham 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. Medway 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 Chatham High Street kitchen sits in a tighter band than a daytime Military Road cafe. We measure the grease load and confirm your interval.
Yes. We work overnight, early mornings and closing days for the Chatham High Street and Military Road kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes - from Chatham High Street and Military Road kitchens to the offices, schools and industrial units across Chatham and the wider Kent.
Yes. The fan at the top of a Pentagon 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.
Little, if it is planned. We survey the Chatham run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Military Road cookline is back in service for the next shift.
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 Chatham High Street and Pentagon where the runs are long and awkward.
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 Pentagon conversions where the run was boxed in with no hatches.
