Winchester · 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 Winchester, and certify it to the TR19 Grease standard your insurer expects.
Winchester
Winchester rates around 1,150 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 - Jewry Street, High Street, Brooks - 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.
The same crews clean dry ventilation and air-handling ductwork in offices, schools and civic buildings, plus the combustible lint runs behind hotel and care-home dryers. High-turnover sites - the University of Winchester, the Royal Hampshire County Hospital, the Brooks centre and the city hotels - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Winchester 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 Jewry Street and Brooks, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Winchester 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 Winchester hotels, care homes and gyms.
On the ground in Winchester
We are in Winchester's ductwork and plant every week. The proof is the jobs, not the stock photos.
A cathedral-precinct restaurant in Winchester 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 hygiene standard. The historic precinct setting meant hoses were routed carefully to protect the fabric.
When it is due
Ductwork rarely warns you politely. In a busy Winchester kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Jewry Street line, a rim of grease at the filters, or a Winchester insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying High Street kitchen needs it far more often than a quiet cafe - and your certificate sets the date, so nothing is left to chance.
How it runs
Inspect the full Winchester 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 Brooks 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 Winchester fire logbook.
Why it matters
Three duties push every Winchester 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 Winchester 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 Jewry 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 Winchester 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. Winchester City 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 Jewry Street kitchen sits in a tighter band than a daytime High Street cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Winchester run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a High Street cookline is back in service for the next shift.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Jewry Street operator's insurer and fire risk assessor expect.
Yes. The fan at the top of a Brooks 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 Winchester offices, schools and public buildings, and the lint-heavy laundry ducts in the Hampshire hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Jewry Street and High Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
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 Jewry Street and Brooks where the runs are long and awkward.
