Hertford · TR19 Grease
We degrease the canopy, baffle filters and extractor fan for Hertford restaurants, takeaways and pubs - so the system pulls properly, runs cooler and holds a current TR19 certificate.
Hertford
Hertford fries hard along Fore Street, Old Cross and St Andrew Street, where the town centre restaurants, takeaways and cafes run their extraction flat out through every service.
The venues change but the grease does not. From Old Cross to St Andrew Street and the suburban parades, the takeaways and grill houses set the toughest test any extraction canopy meets. Hertford rates hundreds of food premises, most of them frying hard in a tight footprint.
We degrease the part of the system the Old Cross and St Andrew 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 Hertford 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 Old Cross 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 St Andrew Street 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 Hertford 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 Hertford's residential streets; cleaned or changed so the downstream stages are not overwhelmed.
Fire
A Hertford 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 Old Cross 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 an Old Cross 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 St Andrew Street system that a quick canopy wipe misses.
On the ground in Hertford
We are under Hertford's canopies every week. Real jobs, not stock shots.
A busy tea room in Hertford had its canopy and fan housing caked in grease from steady service on the chargrill. We degreased the canopy and first bend of the duct to bare metal, cleaned the fan and reset the filters. The system was cleaned to TR19 standard with airflow over the range restored, and we left a report and photos for their file. We fitted the visit around opening time so regulars weren't disturbed.
Why it pays
Extraction cleaning is a fire-risk job first - but it pays back every Hertford service.
A clean canopy and fan pull heat and steam off a hard Old Cross cookline faster, so the kitchen sits cooler and the fan draws less to shift the same air. A greased system is a fire risk, a failed inspection point and a comfort problem all at once. How often it is needed follows how hard you cook - the St Andrew Street takeaways far more than a daytime cafe - and your certificate fixes the interval.
Inspect the Hertford 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 Old Cross or St Andrew Street kitchen sits in a tighter band than a daytime cafe.
Yes. Most venues we clean around Old Cross and St Andrew 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.
It can. An inspection covers the physical condition of the premises, ventilation included, so a grease-laden canopy or fan over a Fore Street cookline can count against your score.
Yes. The takeaways and grill houses around St Andrew Street and Maidenhead 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.
Yes - from Old Cross, St Andrew Street and the city centre out to the suburbs, and across the wider Hertfordshire.
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 St Andrew Street takeaway canopies that have run hot for years.
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 Old Cross kitchen - we clean the full run to TR19 and certify it together.
Local knowledge
Hertford Castle guarded the ford where the harts crossed the Lea, and its Norman motte and surviving brick gatehouse sheltered kings and queens, with the young Elizabeth I among the children raised within its walls. The town turns on food and hospitality now more than on royal residence, 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.
