Sevenoaks · 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 Sevenoaks, and certify it to the TR19 Grease standard your insurer expects.
Sevenoaks
Sevenoaks 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.
The city's kitchens sit in tight, mixed stock - High Street, London Road, Riverhead - with long concealed duct runs up to roof fans. We clean the full run to the TR19 Grease standard, canopy to fan, including the horizontal and vertical sections a canopy-only clean leaves coated.
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 - school and care-home kitchens, hotel and pub kitchens and the busy town-centre takeaways - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Sevenoaks insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard is written in film thickness: once grease reaches a set depth the run has to be cleaned and proven again. In the crowded roof voids off High Street and Riverhead, a wipe of the canopy and filters never reaches the ductwork behind them, where the grease that carries fire quietly gathers. We work the whole Sevenoaks run through hatches already in place and others we cut, bring it back to bright metal, note grease depths at fixed stations before and after, and certify to TR19 Grease with the closing figures logged.
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 Sevenoaks hotels, care homes and gyms.
On the ground in Sevenoaks
We are in Sevenoaks's ductwork and plant every week. The proof is the jobs, not the stock photos.
An apartment block in the centre of Sevenoaks had rotting refuse built into a slime layer down the waste chute, with a foul smell drifting into the bin store. We cleared the chute with a hot-wash spinning head and applied a sanitising treatment from top to bottom. The residue and smell were gone, the chute smooth and hygienic once more, and the difference was obvious straight away. The building manager kept us going with cups of tea through the morning.
When it is due
Ductwork rarely warns you politely. In a busy Sevenoaks kitchen these are the tells.
A canopy dripping onto a High Street cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Sevenoaks 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 London Road 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 Sevenoaks 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 Riverhead 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 Sevenoaks fire logbook.
Why it matters
Three duties push every Sevenoaks 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 Sevenoaks 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. To a Sevenoaks 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. Sevenoaks District 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 High Street kitchen sits in a tighter band than a daytime London Road cafe. We measure the grease load and confirm your interval.
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 High Street and Riverhead where the runs are long and awkward.
Yes - from High Street and London Road kitchens to the offices, schools and industrial units across Sevenoaks and the wider Kent.
Yes. We clean the dry ductwork and air-handling in Sevenoaks offices, schools and public buildings, and the lint-heavy laundry ducts in the Kent hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the High Street and London Road 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 Riverhead 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.
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.
Local knowledge
The railway reached Sevenoaks in 1862 and again through the mile-long Sevenoaks Tunnel in 1868, turning a quiet market town into a London commuter town and drawing goods yards, workshops and warehouses to Bat and Ball. Those trades have largely gone, and modern premises hide their dust and grease inside sealed ductwork instead, where debris builds 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.
