Lincoln · 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 Lincoln, and certify it to the TR19 Grease standard your insurer expects.
Lincoln
Lincoln rates around 1,100 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 - Bailgate, Steep Hill, West End - 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 - the University of Lincoln, Lincoln County Hospital, the LNER Stadium and the city hotels - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Lincoln 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 Bailgate and West End, 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 Lincoln 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 Lincoln hotels, care homes and gyms.
On the ground in Lincoln
We are in Lincoln's ductwork and plant every week. The proof is the jobs, not the stock photos.
A cathedral-city hotel kitchen in Lincoln had a heavy grease film and sticky oil collecting at the vertical exhaust chimney junction, flagged as an insurance risk. We hand-scraped the accessible duct lengths, treated the lines with an enzyme degreaser and wiped the impeller blades clean, satisfying the fire-insurance and environmental-health standards. It was worked through the night so the hotel breakfast service was undisturbed.
When it is due
Ductwork rarely warns you politely. In a busy Lincoln kitchen these are the tells.
Watch for steam that hangs in the room, cooking smells creeping back over the tables, a canopy weeping onto a Bailgate line, grease crusting at the filter rims, or a Lincoln insurer or fire assessor calling for a TR19 certificate you do not hold. How often it needs doing rides on the cooking load - a hard-frying Steep Hill kitchen far more than a quiet daytime cafe - and the certificate fixes that interval, so the next clean is planned, not chanced.
How it runs
Inspect the full Lincoln 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 West End 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 Lincoln fire logbook.
Why it matters
Three duties push every Lincoln 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 Lincoln 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 Bailgate 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 Lincoln 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 City of Lincoln 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 Bailgate kitchen sits in a tighter band than a daytime Steep Hill cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Lincoln run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Steep Hill cookline is back in service for the next shift.
Yes. The fan at the top of a West End 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 West End conversions where the run was boxed in with no hatches.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Bailgate operator's insurer and fire risk assessor expect.
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 Bailgate and West End where the runs are long and awkward.
Yes. We clean the dry ductwork and air-handling in Lincoln offices, schools and public buildings, and the lint-heavy laundry ducts in the Lincolnshire hotels and care homes, alongside kitchen grease ducts.
