Prescot · TR19 Grease
We degrease the canopy, baffle filters and extractor fan for Prescot restaurants, takeaways and pubs - so the system pulls properly, runs cooler and holds a current TR19 certificate.
Prescot
Prescot fries hard around Whiston, Sewell Street and Eccleston Street, where takeaways, chip shops and cafes run their extraction flat out through every service.
The settings vary, the grease does not. Across Whiston, Sewell Street and the suburban strips, the takeaways and grill houses run the single hardest test an extraction canopy faces. Prescot rates hundreds of food premises, most of them frying in a tight footprint.
What the Whiston and Sewell Street cooks labour under - canopy, baffle filters and extractor fan - is exactly what we degrease. Cleaned right it draws as it was meant to, clearing heat and steam, carrying a current TR19 Grease certificate and running cooler, since a clean Prescot fan no longer battles a greased one to shift the same air.
The system
Extraction cleaning is the accessible heart of the system - the kit above a hard-frying Whiston 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 Sewell Street service. The work meets the TR19 Grease standard, with before-and-after evidence and a certificate, so the system pulls properly and your Prescot 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 Prescot's residential streets; cleaned or changed so the downstream stages are not overwhelmed.
Fire
A Prescot 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 Whiston 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 Whiston 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 Sewell Street system that a quick canopy wipe misses.
On the ground in Prescot
We are under Prescot's canopies every week. Real jobs, not stock shots.
Baked-on grease coated the canopy and fan housing at a long-established Prescot nursery kitchen, well past a safe level over the pizza oven. I soaked the filters, scraped the canopy, filters and plenum and washed the duct down to the fan. The canopy passed its grease-depth check with the airflow over the range restored, and I left full documentation for their records. The head chef kept us going with fresh coffee through the morning.
Why it pays
Extraction cleaning is a fire-risk job first - but it pays back every Prescot service.
A clean canopy and fan clear the heat and steam off a hard Whiston 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 Sewell Street takeaways need it more often than a daytime cafe - and your certificate sets the interval.
Inspect the Prescot 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 Whiston or Sewell Street kitchen sits in a tighter band than a daytime cafe.
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 Whiston kitchen - we clean the full run to TR19 and certify it together.
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 Sewell Street takeaway canopies that have run hot for years.
It can. An inspection covers the physical condition of the premises, ventilation included, so a grease-laden canopy or fan over an Eccleston Street cookline can count against your score.
Yes - from Whiston, Sewell Street and the city centre out to the suburbs, and across the wider Merseyside.
Yes. Beyond restaurants, Prescot has the hospital, restaurant and town-centre kitchens we clean and certify - high-volume systems we clean and certify alongside the hospitality work.
Yes. Most venues we clean around Whiston and Sewell 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.
Local knowledge
Prescot grew up as a market town on a sandstone ridge above the Lancashire plain, its narrow streets and old workshops packed tight around the parish church and the cobbles of Eccleston Street. Those close quarters are exactly where the town's kitchens fry hardest today, and busy canopies coat their extract systems in grease every service. Left in place that grease feeds flame and starves airflow, so we strip, degrease and certify extraction from the filter to the fan to the TR19 grease standard.
