Cheshunt · TR19 Grease
We clean the full commercial duct run - grease, dry and laundry ductwork, canopy to roof fan - for kitchens, offices and industrial sites across Cheshunt, and certify it to the TR19 Grease standard your insurer expects.
Cheshunt
Cheshunt rates hundreds of food premises, and behind a large share sits an extract duct a canopy clean never reaches - plus the dry ductwork and air-handling that keep its offices and public buildings running.
Right across Cheshunt, from Old Pond through Turners Hill to Flamstead End, cooklines share tight roof space and vent through concealed ducting few operators ever see inside. We clean that entire path to the TR19 Grease standard, canopy through to fan, taking in the level pulls and the risers where grease settles thickest and a fire would run.
Beyond the kitchens, we clean the dry ductwork and air-handling in offices, schools and public buildings, and the lint-heavy laundry ducts in hotels and care homes. High-output kitchens - Hertford Regional College, the Lee Valley White Water Centre, the Brookfield centre and the town hotels - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Cheshunt insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Grease is measured by thickness, and the standard sets the depth at which a system must be cleaned and re-tested. Around Old Pond and Flamstead End, where the concealed runs thread through mixed roof voids, a canopy-and-filter wipe leaves the ductwork itself - the long hidden sections where grease accumulates and a fire travels - untouched. We access the full Cheshunt run through existing and newly fitted inspection hatches, clean to bare metal, record before-and-after grease-depth readings at set points, and issue a TR19 Grease certificate with a post-clean depth record.
By system
The fire risk. Fried-food extract coats duct walls in combustible grease; cleaned canopy to fan and certified to TR19 Grease.
Supply and general extract in offices and public buildings, carrying dust and debris that throttles airflow and loads the air-handling unit; cleaned to TR19.
The hidden one. Tumble-dryer ducting packs with lint - highly combustible - in Cheshunt hotels, care homes and gyms.
On the ground in Cheshunt
We are in Cheshunt's ductwork and plant every week. The proof is the jobs, not the stock photos.
An Old Pond restaurant in Cheshunt had a heavy grease film through the horizontal extract and up the riser above a busy cook line. We fitted new access panels, hand-scraped the accessible lengths and ran an enzyme degreaser through the sealed sections, returning the ductwork to clean metal for the fire and insurance standard. It was worked overnight so the town-centre trade lost no covers.
When it is due
Ductwork rarely warns you politely. In a busy Cheshunt kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto an Old Pond line, a rim of grease at the filters, or a Cheshunt insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Turners Hill kitchen needs it far more often than a quiet cafe - and your certificate sets the date, so nothing is left to chance.
How it runs
Inspect the full Cheshunt run, find the access gaps in the concealed sections, agree scope and frequency.
Fit inspection hatches where the run is sealed - common in the older Flamstead End conversions - and protect the kitchen.
Canopy to roof fan, down to bare metal, with before-and-after grease-depth evidence.
TR19 Grease certificate, grease-depth record and next-due date for your Cheshunt fire logbook.
Why it matters
Three duties push every Cheshunt operator to keep ductwork clean, and they reinforce one another.
Fire safety law. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for a Cheshunt premises must assess and manage fire risk. A grease-laden duct is one of the most serious risks in any catering building, because a flare-up on an Old Pond cookline can travel the ductwork and spread fire through concealed voids. The Health and Safety at Work etc. Act 1974 and the HSE reinforce the same duty of care.
Insurance. A current TR19 Grease certificate is the evidence your Cheshunt insurer expects. Without it, a fire claim can be reduced or refused outright - an expensive gap to find after the event.
Hygiene and environmental health. When Broxbourne Borough Council carries out a food hygiene inspection it judges the physical state of the premises, and ventilation is part of that. A grease-choked extract can pull down the rating an Environmental Health Officer gives, on top of the odour and the weakening airflow your staff put up with.
It is set by cooking hours under TR19 Grease - roughly every three months for heavy use of 12 to 16 hours a day, every six for moderate, every twelve for light. A hard-frying Old Pond kitchen sits in a tighter band than a daytime Turners Hill cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Cheshunt run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Turners Hill cookline is back in service for the next shift.
Yes. The fan at the top of a Flamstead End or city-centre riser is where grease throws off the blades and the run ends - we degrease it and its housing, because a loaded fan is what finally stops a system pulling.
Yes. We clean the dry ductwork and air-handling in Cheshunt offices, schools and public buildings, and the lint-heavy laundry ducts in the Hertfordshire hotels and care homes, alongside kitchen grease ducts.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence an Old Pond operator's insurer and fire risk assessor expect.
Yes. We work overnight, early mornings and closing days for the Old Pond and Turners Hill kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes - from Old Pond and Turners Hill kitchens to the offices, schools and industrial units across Cheshunt and the wider Hertfordshire.
