Darlington · TR19 Grease
We degrease the canopy, baffle filters and extractor fan for Darlington restaurants, takeaways and pubs - so the system pulls properly, runs cooler and holds a current TR19 certificate.
Darlington
Darlington fries across the town - the Skinnergate and Grange Road cooklines cook from open to close, and the Duke Street and Bondgate kitchens run alongside.
The settings vary, the grease does not. Across Duke Street, Blackwellgate and the suburban strips, the takeaways and grill houses run the single hardest test an extraction canopy faces. Darlington rates around 900 food premises, most of them frying in a tight footprint.
The kit the Duke Street and Blackwellgate cooks work beneath - canopy, baffle filters and extractor fan - is what we degrease. Done right it pulls the way it should, clearing heat and steam, backed by a current TR19 Grease certificate, and it runs cooler too, because a clean Darlington fan is not working against a greased one to move the same air.
The system
Extraction cleaning is the accessible heart of the system - the kit above a hard-frying Duke Street cookline that does the work and shows the grease first.
The canopy is stripped inside and out, the baffle filters cleaned or renewed, and the extractor fan and housing degreased - it is the fan that slips quietly as grease weighs its blades through a hard Blackwellgate service. All of it is taken to the TR19 Grease standard, with before-and-after evidence and a certificate, so the system draws as designed and your Darlington fire risk assessment and insurer hold the record they expect.
Filters
The standard for commercial cooklines: they trap grease and slow flame spread. Cleaned, or replaced when warped or corroded.
Common on older or lighter setups; they clog fast and pass grease through if neglected. We flag where a baffle upgrade is overdue.
On the odour and emission-controlled systems near Darlington's residential streets; cleaned or changed so the downstream stages are not overwhelmed.
Fire
A Darlington cookline's extraction and its fire protection are one system - and a clean is the moment to check the join.
Nozzles aimed at the canopy and cooking points; grease build-up around them on a busy Duke Street line is exactly what they exist to fight. We clean around them without disturbing the system.
Where the gas shuts off if extraction fails on a Duke Street line, we work without tripping it - and flag it if it is not behaving.
Checked for the grease that would stop them closing - a quiet failure point on a Blackwellgate system that a quick canopy wipe misses.
On the ground in Darlington
We are under Darlington's canopies every week. Real jobs, not stock shots.
A retail-park diner in Darlington had carbonised grease throughout its ventilation system after a long stretch without a professional clean. We ran a full system deep-clean, hand-cleaning the access points and working rotary brush systems through every duct section to strip the buildup. The grease-fire risk was cleared and the system brought back into compliance, on an overnight shift.
Why it pays
Extraction cleaning is a fire-risk job first - but it pays back every Darlington service.
A clean canopy and fan clear the heat and steam off a hard Duke Street cookline faster, so the kitchen runs cooler and the fan draws less to move the same air. A greased system is a fire risk, a failed inspection point and a comfort problem at once. Frequency tracks how hard you cook - the Blackwellgate takeaways need it more often than a daytime cafe - and your certificate sets the interval.
Inspect the Darlington canopy, filters and fan, agree scope and frequency.
Remove filters and access panels, protect the cookline.

Questions
It depends how hard the kitchen runs. Under TR19 Grease, heavy use of 12 to 16 hours a day points to roughly every three months, moderate to every six, light to every twelve. A busy Duke Street or Blackwellgate kitchen sits in a tighter band than a daytime cafe.
Yes - from Duke Street, Blackwellgate and the city centre out to the suburbs, and across the wider County Durham.
Yes. Where a filter is warped, corroded or a mesh type that keeps passing grease, we say so and swap it - common on the older Blackwellgate takeaway canopies that have run hot for years.
Yes. Most venues we clean around Duke Street and Blackwellgate are busy through the evening, so we work overnight, early mornings or on closing days, at no extra charge for out-of-hours work.
Yes. Beyond restaurants, Darlington has campus catering at Darlington College, production kitchens at Darlington Memorial Hospital, and stadium and hotel kitchens - high-volume systems we clean and certify alongside the hospitality work.
Extraction cleaning covers the canopy, filters and fan; where the concealed duct run behind them is also loaded - as it often is in a tight Duke Street kitchen - we clean the full run to TR19 and certify it together.
Yes. The takeaways and grill houses around Blackwellgate and Grange Road run a canopy, filters and a fan and often carry a heavy grease load for their size. We clean and certify them the same way as a full restaurant system.
