Canterbury · 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 Canterbury, and certify it to the TR19 Grease standard your insurer expects.
Canterbury
Canterbury 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 Canterbury, from St George's Street through High Street to Northgate, 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.
It is not only kitchens: we also clean the dry supply and extract ductwork in Canterbury offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - EKC Canterbury College, the Kent and Canterbury Hospital, the Whitefriars quarter and the city hotels - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Canterbury 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 St George's Street and Northgate, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Canterbury 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 Canterbury hotels, care homes and gyms.
On the ground in Canterbury
We are in Canterbury's ductwork and plant every week. The proof is the jobs, not the stock photos.
A St George's Street restaurant in Canterbury had a heavy grease film through the horizontal extract and up the riser above a busy cook line. We fitted 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 city-centre trade lost no covers.
When it is due
Ductwork rarely warns you politely. In a busy Canterbury kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a St George's Street cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Canterbury insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying High Street kitchen needs it far more often than a daytime cafe - and your certificate states the interval, so the next clean is never a guess.
How it runs
Inspect the full Canterbury 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 Northgate conversions - and protect the kitchen.
Canopy to roof fan, down to bare metal, with before-and-after grease-depth evidence.

Why it matters
Three duties push every Canterbury 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 Canterbury 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 St George's 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 current TR19 Grease certificate is the evidence your Canterbury 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 Canterbury City 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 St George's Street kitchen sits in a tighter band than a daytime High Street cafe. We measure the grease load and confirm your interval.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a St George's Street operator's insurer and fire risk assessor expect.
Yes - from St George's Street and High Street kitchens to the offices, schools and industrial units across Canterbury and the wider Kent.
Yes. We clean the dry ductwork and air-handling in Canterbury offices, schools and public buildings, and the lint-heavy laundry ducts in the Kent hotels and care homes, alongside kitchen grease ducts.
Yes. The fan at the top of a Northgate 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.
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 St George's Street and Northgate 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 Northgate conversions where the run was boxed in with no hatches.
