Northallerton · 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 Northallerton, and certify it to the TR19 Grease standard your insurer expects.
Northallerton
Northallerton rates dozens 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.
Right across Northallerton, from High Street through Zetland Street to College Road, cooklines share tight roof space and vent through concealed ducting few operators ever see inside. We clean that entire path to the TR19 Grease standard, canopy through to fan, taking in the level pulls and the risers where grease settles thickest and a fire would run.
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 High Street tearooms, the Friarage Hospital kitchens and the County Hall canteens - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Northallerton insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Because the standard is written around film thickness, it sets the depth that triggers a clean and re-test. In the mixed roof spaces around High Street and College Road, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Northallerton run through existing hatches and new ones we cut, clean back to bright metal, take before-and-after grease-depth figures at set points, and certify it to TR19 Grease with those depths on the 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 Northallerton hotels, care homes and gyms.
On the ground in Northallerton
We are in Northallerton's ductwork and plant every week. The proof is the jobs, not the stock photos.
A church hall in Northallerton had its branch supply ducts thick with dust behind the grilles, leaving stuffy air through the main rooms. We isolated the zones, brushed out the internal ducting and washed the ceiling diffusers, so the air through the occupied rooms felt noticeably fresher and the dust complaints stopped. The hall committee booked a regular clean to keep it that way.
When it is due
Ductwork rarely warns you politely. In a busy Northallerton kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a High Street cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Northallerton insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Zetland Street 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 Northallerton 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 College Road 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 Northallerton fire logbook.
Why it matters
Three duties push every Northallerton 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 Northallerton 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 High 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 Northallerton 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. When North Yorkshire Council carries out a food hygiene inspection it judges the physical state of the premises, and ventilation is part of that. A grease-choked extract can pull down the rating an Environmental Health Officer gives, on top of the odour and the weakening airflow your staff put up with.
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 High Street kitchen sits in a tighter band than a daytime Zetland Street cafe. We measure the grease load and confirm your interval.
Yes. We work overnight, early mornings and closing days for the High Street and Zetland Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes. We clean the dry ductwork and air-handling in Northallerton offices, schools and public buildings, and the lint-heavy laundry ducts in the North Yorkshire hotels and care homes, alongside kitchen grease ducts.
Yes - from High Street and Zetland Street kitchens to the offices, schools and industrial units across Northallerton and the wider North Yorkshire.
Yes. The fan at the top of a College Road 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 College Road 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 High Street operator's insurer and fire risk assessor expect.
Local knowledge
Northallerton's prison opened in 1788 as the first purpose-built jail in England, and by the 1820s held the largest treadmill in the world; the site reopened in 2015 as the Treadmills retail and business quarter. Ductwork carries its own hidden burden - grease, dust and debris settling out of sight until airflow drops or fire risk climbs. We clean supply and extract ducting back to bare metal, photograph the runs before and after, and leave the system certified to the recognised standard.
