Banbury · 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 Banbury, and certify it to the TR19 Grease standard your insurer expects.
Banbury
Banbury 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 - Parsons Street, Castle Quay, Horsefair - 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 - Banbury and Bicester College, the Horton General Hospital, the Castle Quay centre and the town hotels - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Banbury 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 Parsons Street and Horsefair, 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 Banbury 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 Banbury hotels, care homes and gyms.
On the ground in Banbury
We are in Banbury's ductwork and plant every week. The proof is the jobs, not the stock photos.
A Market Place restaurant in Banbury 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 town-centre trade lost no covers.
When it is due
Ductwork rarely warns you politely. In a busy Banbury kitchen these are the tells.
A canopy dripping onto a Parsons Street cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Banbury 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 Castle Quay 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 Banbury 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 Horsefair 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 Banbury 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 Banbury 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 Parsons 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. Your Banbury 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. Cherwell 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 Parsons Street kitchen sits in a tighter band than a daytime Castle Quay 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 Parsons Street and Horsefair where the runs are long and awkward.
Yes. The fan at the top of a Horsefair 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.
Yes. We clean the dry ductwork and air-handling in Banbury offices, schools and public buildings, and the lint-heavy laundry ducts in the Oxfordshire hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Parsons Street and Castle Quay kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes - from Parsons Street and Castle Quay kitchens to the offices, schools and industrial units across Banbury and the wider Oxfordshire.
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 Horsefair conversions where the run was boxed in with no hatches.
