Bishop Auckland · 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 Bishop Auckland, and certify it to the TR19 Grease standard your insurer expects.
Bishop Auckland
Bishop Auckland 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 - Newgate Street, Fore Bondgate, Tenters Street - 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.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Bishop Auckland schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - Bishop Auckland College, Bishop Auckland Hospital, the Auckland Project 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 Bishop Auckland 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 Newgate Street and Tenters Street, 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 Bishop Auckland 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 Bishop Auckland hotels, care homes and gyms.
On the ground in Bishop Auckland
We are in Bishop Auckland's ductwork and plant every week. The proof is the jobs, not the stock photos.
A Newgate Street restaurant in Bishop Auckland 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 Bishop Auckland kitchen these are the tells.
A canopy dripping onto a Newgate Street cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Bishop Auckland 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 Fore Bondgate 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 Bishop Auckland 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 Tenters Street 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 Bishop Auckland fire logbook.
Why it matters
Three duties push every Bishop Auckland 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 Bishop Auckland 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 Newgate 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 Bishop Auckland 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. Durham County 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 Newgate Street kitchen sits in a tighter band than a daytime Fore Bondgate cafe. We measure the grease load and confirm your interval.
Yes. The fan at the top of a Tenters Street 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.
Little, if it is planned. We survey the Bishop Auckland run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Fore Bondgate 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 Newgate Street operator's insurer and fire risk assessor expect.
Yes. We clean the dry ductwork and air-handling in Bishop Auckland offices, schools and public buildings, and the lint-heavy laundry ducts in the County Durham hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Newgate Street and Fore Bondgate 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 Newgate Street and Tenters Street where the runs are long and awkward.
