Aylesbury · 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 Aylesbury, and certify it to the TR19 Grease standard your insurer expects.
Aylesbury
Aylesbury 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.
From Market Square to Friars Square and Temple 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.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Aylesbury schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - Aylesbury College, Stoke Mandeville Hospital, the Waterside Theatre and the town hotels - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Aylesbury insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Grease is measured by thickness, and the standard sets the depth at which a system must be cleaned and re-tested. Around Market Square and Temple Street, where the concealed runs thread through mixed roof voids, a canopy-and-filter wipe leaves the ductwork itself - the long hidden sections where grease accumulates and a fire travels - untouched. We access the full Aylesbury run through existing and newly fitted inspection hatches, clean to bare metal, record before-and-after grease-depth readings at set points, and issue a TR19 Grease certificate with a post-clean depth 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 Aylesbury hotels, care homes and gyms.
On the ground in Aylesbury
We are in Aylesbury's ductwork and plant every week. The proof is the jobs, not the stock photos.
A spinal-unit hospital kitchen in Aylesbury had grease creeping through the main extract run and up the discharge stack from a busy cook line. We opened fresh access panels, hand-scraped the heavy deposits and treated the runs with a food-safe degreaser, bringing the ductwork back to bare metal for the NHS fire and hygiene standard. The work was staged around the ward meal service so the kitchen kept running.
When it is due
Ductwork rarely warns you politely. In a busy Aylesbury kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Market Square cookline, extraction that no longer clears the steam, visible grease at the filter edges, or an Aylesbury insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Friars Square 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 Aylesbury 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 Temple Street 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 Aylesbury 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 an Aylesbury 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 Market Square 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. Your Aylesbury insurer expects a current TR19 Grease certificate as proof the duct is clean. Without one, a fire claim can be cut back or turned down altogether - a costly thing to find only after a fire.
Hygiene and environmental health. Food hygiene inspections by Buckinghamshire Council take in the condition of the building, ventilation included, so a grease-laden system can cost you on the rating an Environmental Health Officer awards - never mind the smell and the dropping extraction your kitchen team works under.
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 Market Square kitchen sits in a tighter band than a daytime Friars Square 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 Market Square 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 Temple Street conversions where the run was boxed in with no hatches.
Yes - from Market Square and Friars Square kitchens to the offices, schools and industrial units across Aylesbury and the wider Buckinghamshire.
Yes. We clean the dry ductwork and air-handling in Aylesbury offices, schools and public buildings, and the lint-heavy laundry ducts in the Buckinghamshire hotels and care homes, alongside kitchen grease ducts.
Little, if it is planned. We survey the Aylesbury run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Friars Square cookline is back in service for the next shift.
Yes. We work overnight, early mornings and closing days for the Market Square and Friars Square kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
