Hemel Hempstead · TR19 Grease
We degrease the canopy, baffle filters and extractor fan for Hemel Hempstead restaurants, takeaways and pubs - so the system pulls properly, runs cooler and holds a current TR19 certificate.
Hemel Hempstead
Hemel Hempstead fries across the new town - the Marlowes and Riverside cooklines cook from open to close, and the Old Town and Water Gardens kitchens run alongside.
The venues change but the grease does not. From Water Gardens to Leverstock Green and the suburban parades, the takeaways and grill houses set the toughest test any extraction canopy meets. Hemel Hempstead rates around 1,250 food premises, most of them frying hard in a tight footprint.
What the Water Gardens and Leverstock Green 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 Hemel Hempstead 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 Water Gardens 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 Leverstock Green service. Cleaned to the TR19 Grease standard, with before-and-after evidence and a certificate, so the system pulls properly and your Hemel Hempstead 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 Hemel Hempstead's residential streets; cleaned or changed so the downstream stages are not overwhelmed.
Fire
A Hemel Hempstead 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 Water Gardens 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 Water Gardens 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 Leverstock Green system that a quick canopy wipe misses.
On the ground in Hemel Hempstead
We are under Hemel Hempstead's canopies every week. Real jobs, not stock shots.
An upmarket suburban bistro in Hemel Hempstead had an odour-retaining grease film through a residential-style extraction unit. We ran a duct-wide degrease with an odour-neutralisation flush, clearing the smell and restoring the airflow, keeping to the residential building's quiet hours.
Why it pays
Extraction cleaning is a fire-risk job first - but it pays back every Hemel Hempstead service.
A clean canopy and fan clear the heat and steam off a hard Water Gardens 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 Leverstock Green takeaways need it more often than a daytime cafe - and your certificate sets the interval.

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 Water Gardens or Leverstock Green kitchen sits in a tighter band than a daytime cafe.
Yes. Most venues we clean around Water Gardens and Leverstock Green are busy through the evening, so we work overnight, early mornings or on closing days, at no extra charge for out-of-hours work.
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 Water Gardens kitchen - we clean the full run to TR19 and certify it together.
Yes - from Water Gardens, Leverstock Green 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 Leverstock Green takeaway canopies that have run hot for years.
Yes. Beyond restaurants, Hemel Hempstead has campus catering at West Herts College, production kitchens at Hemel Hempstead Hospital, and shopping-centre and hotel kitchens - 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 Marlowes cookline can count against your score.
