Darwen · TR19 Grease
We degrease the canopy, baffle filters and extractor fan for Darwen restaurants, takeaways and pubs - so the system pulls properly, runs cooler and holds a current TR19 certificate.
Darwen
Darwen fries hard along Bolton Road, Duckworth Street and Croft Street, where chip shops, takeaways and cafes run their extraction flat out through every service.
Different kitchens, same grease. Around Bolton Road, Croft Street and the outlying strips, the grill houses and takeaways put an extraction canopy through the hardest work it will ever do. With hundreds of food premises rated across Darwen, most are frying in a cramped space.
We degrease the part of the system the Bolton Road and Croft Street cooks work under - the canopy, the baffle filters and the extractor fan. Done properly it pulls the way it was designed to, clearing heat and steam, holding a current TR19 Grease certificate, and running cooler, because a clean Darwen fan is not fighting 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 Bolton Road cookline that does the work and shows the grease first.
Canopy inside and out, baffle filters cleaned or replaced, and the extractor fan and housing degreased - that last part loses performance quietly as grease builds on the blades through a hard Croft Street service. The work meets the TR19 Grease standard, with before-and-after evidence and a certificate, so the system pulls properly and your Darwen fire risk assessment and insurer have the paperwork they ask for.
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 Darwen's residential streets; cleaned or changed so the downstream stages are not overwhelmed.
Fire
A Darwen 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 Bolton Road 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 Bolton Road 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 Croft Street system that a quick canopy wipe misses.
On the ground in Darwen
We are under Darwen's canopies every week. Real jobs, not stock shots.
A much-loved pizzeria in Darwen had thick grease collected through the canopy and fan housing, cutting the pull over the griddle. We cleaned the plenum and filters back to metal, degreased the fan housing and refitted the cleaned filters. The canopy and duct came up clean and safe and drawing properly once more, with photos, a report and a certificate handed over. The site's golden retriever kept a close eye on us from a bench by the door.
Why it pays
Extraction cleaning is a fire-risk job first - but it pays back every Darwen service.
A clean canopy and fan clear the heat and steam off a hard Bolton Road 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 Croft Street takeaways need it more often than a daytime cafe - and your certificate sets the interval.
Inspect the Darwen 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 Bolton Road or Croft Street kitchen sits in a tighter band than a daytime cafe.
It can. An inspection covers the physical condition of the premises, ventilation included, so a grease-laden canopy or fan over a Duckworth Street cookline can count against your score.
Every clean finishes with a dated TR19 certificate, before-and-after photographs and a condition report - the evidence a Bolton Road operator's insurer or fire risk assessor expects to see.
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 Bolton Road kitchen - we clean the full run to TR19 and certify it together.
Yes. Most venues we clean around Bolton Road and Croft Street 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 - from Bolton Road, Croft Street and the city centre out to the suburbs, and across the wider Lancashire.
Yes. The takeaways and grill houses around Croft Street and Market Street 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.
Local knowledge
Long before the Kinder trespass of 1932, Darwen won its own fight for the open moor - in 1896 the townsfolk secured public access to Darwen Moor, and the octagonal Jubilee Tower was raised on the hill in 1898 to mark both the victory and Victoria's Diamond Jubilee. The town's trade turns on food now, and busy kitchens coat their canopies and extract systems in grease every service. Left in place it feeds flame and starves airflow, so we strip, degrease and certify extraction from the filter to the fan to the TR19 grease standard.
