Woking · 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 Woking, and certify it to the TR19 Grease standard your insurer expects.
Woking
Woking rates around 760 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 - Commercial Way, Chertsey Road, Horsell - 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.
It is not only kitchens: we also clean the dry supply and extract ductwork in Woking offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - the local college, the McLaren Technology Centre, the Victoria Place centre and the town hotels - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Woking 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 Commercial Way and Horsell, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Woking 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 Woking hotels, care homes and gyms.
On the ground in Woking
We are in Woking's ductwork and plant every week. The proof is the jobs, not the stock photos.
A commercial-way restaurant in Woking had a thick amber grease film coating the horizontal extract runs and the vertical riser up to the roof cowl. We fitted two new access panels, hand-scraped the accessible lengths and ran an enzyme degreaser through the sealed sections, returning the ductwork to clean metal for the fire and insurance standard. It was worked overnight so the pedestrianised dining strip kept its full evening service.
When it is due
Ductwork rarely warns you politely. In a busy Woking kitchen these are the tells.
A canopy dripping onto a Commercial Way cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Woking 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 Chertsey 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 Woking 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 Horsell 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 Woking fire logbook.
Why it matters
Three duties push every Woking 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 Woking 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 Commercial Way 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 current TR19 Grease certificate is the evidence your Woking insurer expects. Without it, a fire claim can be reduced or refused outright - an expensive gap to find after the event.
Hygiene and environmental health. A food hygiene visit from Woking Borough Council weighs the physical state of the premises, ventilation counted within it. A grease-blocked extract can pull down the rating an Environmental Health Officer sets, quite apart from the stale smell and the tired airflow your staff work beneath all shift.
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 Commercial Way kitchen sits in a tighter band than a daytime Chertsey Road cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Woking run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Chertsey 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 Commercial Way and Horsell where the runs are long and awkward.
Yes. The fan at the top of a Horsell 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.
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 Horsell conversions where the run was boxed in with no hatches.
Yes. We work overnight, early mornings and closing days for the Commercial Way and Chertsey Road kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes - from Commercial Way and Chertsey Road kitchens to the offices, schools and industrial units across Woking and the wider Surrey.
