Chesham · TR19 Grease
We degrease the canopy, baffle filters and extractor fan for Chesham restaurants, takeaways and pubs - so the system pulls properly, runs cooler and holds a current TR19 certificate.
Chesham
Chesham fries hard along Broad Street and Red Lion Street, where chip shops, takeaways, kebab houses and cafes run their extraction flat out through every service.
The settings vary, the grease does not. Across Red Lion Street, Waterside and the suburban strips, the takeaways and grill houses run the single hardest test an extraction canopy faces. Chesham rates hundreds of food premises, most of them frying in a tight footprint.
What the Red Lion Street and Waterside 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 Chesham 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 Red Lion 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 Waterside 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 Chesham 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 Chesham's residential streets; cleaned or changed so the downstream stages are not overwhelmed.
Fire
A Chesham 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 Red Lion 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 Red Lion 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 Waterside system that a quick canopy wipe misses.
On the ground in Chesham
We are under Chesham's canopies every week. Real jobs, not stock shots.
Thick grease had gathered through the filters and extract duct of a busy Chesham school canteen, choking the pull over the cook line. We cleaned the canopy, filters and plenum down to clean metal, degreased the fan housing and refitted the filters once done. Cleaned to TR19, the system was drawing properly again, with full documentation left for their records. We worked into the mid-afternoon lull so staff weren't disturbed.
Why it pays
Extraction cleaning is a fire-risk job first - but it pays back every Chesham service.
A clean canopy and fan clear the heat and steam off a hard Red Lion 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 Waterside takeaways need it more often than a daytime cafe - and your certificate sets the interval.
Inspect the Chesham 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 Red Lion Street or Waterside kitchen sits in a tighter band than a daytime cafe.
Yes - from Red Lion Street, Waterside and the city centre out to the suburbs, and across the wider Buckinghamshire.
Yes. Most venues we clean around Red Lion Street and Waterside 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, Chesham has the town-centre, pub and workplace kitchens we clean and certify - high-volume systems we clean and certify alongside the hospitality work.
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 Waterside 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 a Broad 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 Red Lion Street operator's insurer or fire risk assessor expects to see.
Local knowledge
The Nash family brewed at Chesham from the 1890s, trademarking the Trident symbol in 1896 and running their Church Street brewery until brewing finally ceased in the town in 1957. Where beer and boots once drove the trade, busy kitchens now 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. The Trident is long gone from the taps, but the grease still builds in every hard-working kitchen the town runs.
