Extraction Cleaning · Welwyn Garden City
Welwyn Garden City's cooklines - Howardsgate restaurants, the food court, employer canteens - load canopy, filters and fan with grease. We strip and degrease the whole extraction system, canopy to fan, and certify it fire-safe to TR19 Grease.

The restaurants of Howardsgate, the Howard Centre food court and the high-volume canteens of the business parks all work their canopies through the day, and grease builds on the filters, up the plenum and into the fan faster than a wipe-down keeps pace with.
As one of Welwyn Hatfield Borough Council's 762 rated premises, a kitchen here shows a greased extraction the usual way - it runs hot and smoky, the hood stops capturing, and the caked filters and fan become a fire load over the flame. We strip, degrease and certify the whole system to TR19 Grease so the pull returns, cleaning the fan itself where the airflow has already gone.
Swapping filters treats the symptom; grease in the canopy, plenum and fan is what actually strangles the airflow. Clean the lot together and the cookline captures again, the kitchen runs cooler, and the fire risk over a live line comes down with it.
It is measured and evidenced to TR19 Grease, with the fan the tell: when a Welwyn Garden City kitchen goes hot and smoky, it is usually grease unbalancing the impeller, not the filters.
The standard on a commercial canopy. We strip, soak and scrape them back, and flag any that are warped or missing - the gap a warped filter leaves lets grease straight into the plenum.
Common on lighter lines and older canopies, and quick to clog solid. We clean what you run and advise where a baffle filter would serve a heavy frying line better.
On enclosed or recirculating systems. We service the stages, check the seals and tell you what needs replacing rather than cleaning.
Many cooklines carry a wet-chemical system built into the canopy. We degrease the filters, canopy and fan without disturbing the nozzles or detection - so you keep both defences.
Where a gas interlock ties the cookline to the extract, we work around it and leave it functioning, so the line cannot fire without the extraction running.
We check and clear accessible fire dampers in the run, so a damper that has to close in a fire is not seized solid with grease.
Real jobs, described by sector and area - never by a client's name.
A staff canteen serving a large employer had loaded its canopy and slowed its fan until the kitchen ran hot at lunch. We stripped and soaked the filters, scraped canopy and duct, and degreased the fan so the extraction pulled properly through the rush again.
A Howardsgate restaurant's extraction had gone weak - grease had reached the impeller. We cleaned the fan with the whole system so the airflow that came back was real, and left a certificate and photographs.
We survey the canopy, filters and fan and gauge the grease loading and how far airflow has dropped.
The line and any suppression system are protected and the area covered before we start.
The whole system is degreased - filters, canopy, plenum and fan - twice over where grease is baked on.
You get the certificate, the before-and-after photographs and a recommended re-clean date.
By cooking volume - TR19 Grease sets the interval by daily cooking hours, and we set a next-due date to your grease loading.
The whole system - filters, canopy, plenum, fan and impeller, and the accessible duct. The greased fan is usually the real cause of weak airflow.
No - we degrease around a wet-chemical system's nozzles and detection without disturbing them.
Yes - Howardsgate, the Howard Centre and the business parks, and across Hertfordshire.
Yes - overnight, early mornings and closed days at no extra charge.

The employer canteens feed full lunch sittings day after day, some of the steadiest extraction loads in the town. Left to load, that grease turns a kitchen hot and becomes a fire risk over the flame. We degrease the whole line so the extraction keeps drawing and stays safe.
We have stripped, degreased and certified commercial extraction to TR19 Grease since 2001, across Hertfordshire and the UK. On a hard-frying line the job is the same every time: the whole system taken back, the fan balanced, and a certificate that satisfies your insurer and fire risk assessor.
Send us your cookline and frying hours and we will survey, strip, degrease and certify - across Hertfordshire.
