Peterlee · 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 Peterlee, and certify it to the TR19 Grease standard your insurer expects.
Peterlee
Peterlee 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 - Yoden Way, Castle Dene, Sunny Blunts - 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.
It is not only kitchens: we also clean the dry supply and extract ductwork in Peterlee offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - canteen kitchens, takeaways, pub and cafe kitchens and the busy town-centre food outlets - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Peterlee 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 Yoden Way and Sunny Blunts, 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 Peterlee 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 Peterlee hotels, care homes and gyms.
On the ground in Peterlee
We are in Peterlee's ductwork and plant every week. The proof is the jobs, not the stock photos.
A well-known Peterlee primary school had its main supply runs coated in fine grey dust, and staff had been complaining of dry eyes and stale air. We cleaned the fresh-air ducting with air whips under negative pressure and renewed the AHU panel filters. Airflow came back up to spec, the system was left visibly clean, and the feedback afterwards was excellent. We slotted the work into a quiet Sunday to suit the practice manager.
When it is due
Ductwork rarely warns you politely. In a busy Peterlee kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Yoden Way line, a rim of grease at the filters, or a Peterlee insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Castle Dene 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 Peterlee 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 Sunny Blunts 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 Peterlee fire logbook.
Why it matters
Three duties push every Peterlee 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 Peterlee 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 Yoden Way 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 Peterlee 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 Durham County 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 Yoden Way kitchen sits in a tighter band than a daytime Castle Dene cafe. We measure the grease load and confirm your interval.
Yes. The fan at the top of a Sunny Blunts 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.
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 Yoden Way and Sunny Blunts where the runs are long and awkward.
Yes - from Yoden Way and Castle Dene kitchens to the offices, schools and industrial units across Peterlee and the wider County Durham.
Yes. We work overnight, early mornings and closing days for the Yoden Way and Castle Dene kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Little, if it is planned. We survey the Peterlee run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Castle Dene cookline is back in service for the next shift.
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 Sunny Blunts conversions where the run was boxed in with no hatches.
Local knowledge
The whole point of Peterlee was work: the Development Corporation raised factory after factory on the estates west of the A19 so the sons and daughters of miners would not have to go down the pit. Where colliery air once hung thick with coal dust, the modern production lines hide their dust and grease inside sealed ductwork instead. Left unchecked it builds unseen until airflow fails or fire finds a path along a run. We clean and inspect ventilation and extract ductwork across the town, then hand over photographic before-and-after evidence of every length.
