Letchworth · TR19 Grease
We degrease the canopy, baffle filters and extractor fan for Letchworth restaurants, takeaways and pubs - so the system pulls properly, runs cooler and holds a current TR19 certificate.
Letchworth
Letchworth fries hard along Leys Avenue, Eastcheap, Nevells Road and Hitchin Road, where cafes, takeaways and chip shops run their extraction flat out through every service.
The venues change but the grease does not. From Nevells Road to Hitchin Road and the suburban parades, the takeaways and grill houses set the toughest test any extraction canopy meets. Letchworth rates hundreds of food premises, most of them frying hard in a tight footprint.
We degrease exactly what the Nevells Road and Hitchin Road cooks stand under - the canopy, the baffle filters and the extractor fan. Cleaned properly the system draws as designed, clearing heat and steam, carrying a current TR19 Grease certificate, and running cooler, since a clean Letchworth fan is not straining against grease to shift the same air.
The system
Extraction cleaning is the accessible heart of the system - the kit above a hard-frying Nevells Road cookline that does the work and shows the grease first.
We strip and degrease the canopy inside and out, clean or replace the baffle filters, and degrease the extractor fan and its housing - the part that quietly loses performance as grease loads the blades over a hard Hitchin Road service. Cleaned to the TR19 Grease standard, with before-and-after evidence and a certificate, so the system pulls properly and your Letchworth fire risk assessment and insurer have the record 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 Letchworth's residential streets; cleaned or changed so the downstream stages are not overwhelmed.
Fire
A Letchworth 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 Nevells 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 Nevells 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 Hitchin Road system that a quick canopy wipe misses.
On the ground in Letchworth
We are under Letchworth's canopies every week. Real jobs, not stock shots.
A high-street sandwich shop in Letchworth had a heavy grease layer over the plenum and filters, a clear fire risk above the griddle. We cleaned the filters and extract duct back to metal, degreased the fan housing and refitted the cleaned filters. The canopy and duct came up clean and safe with much better draw across the canopy, and the paperwork followed by email that afternoon. Access was tight, so we loaded in through the back to reach the far end.
Why it pays
Extraction cleaning is a fire-risk job first - but it pays back every Letchworth service.
Clear the canopy and fan of grease and a hard Nevells Road cookline sheds its heat and steam faster, so the kitchen keeps cooler and the fan works less to move the same air. Leave it caked and you carry a fire risk, a failed inspection point and an uncomfortable kitchen at once. How often it is due tracks the cooking - the Hitchin Road takeaways well beyond a daytime cafe - and your certificate names the next date.
Inspect the Letchworth 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 Nevells Road or Hitchin Road kitchen sits in a tighter band than a daytime cafe.
Yes - from Nevells Road, Hitchin Road and the city centre out to the suburbs, and across the wider Hertfordshire.
Every clean finishes with a dated TR19 certificate, before-and-after photographs and a condition report - the evidence a Nevells 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 Nevells Road kitchen - we clean the full run to TR19 and certify it together.
Yes. Most venues we clean around Nevells Road and Hitchin Road 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, Letchworth has the college, pub and town-centre kitchens we clean and certify - high-volume systems we clean and certify alongside the hospitality work.
It can. An inspection covers the physical condition of the premises, ventilation included, so a grease-laden canopy or fan over a Leys Avenue cookline can count against your score.
Local knowledge
The Spirella factory, the Castle Corset that Cecil Hignett designed between 1912 and 1920, was a factory of beauty with a ballroom and library for its workers, and it still stands as one of the finest Arts and Crafts factories in the country. The town's trade turns on food now more than corsetry, 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.
