Enfield · 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 Enfield, and certify it to the TR19 Grease standard your insurer expects.
Enfield
Enfield rates around 2,400 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.
Kitchens across Enfield work out of tight, mixed premises - Green Lanes, Church Street, Palace Exchange - their extract snaking through concealed voids to roof-mounted fans. We take the whole run to the TR19 Grease standard, hood to fan, reaching the horizontal legs and vertical risers a canopy wipe never touches.
It is not only kitchens: we also clean the dry supply and extract ductwork in Enfield offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - the local college, Chase Farm Hospital, Forty Hall and the borough hotels - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Enfield insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Because the standard is written around film thickness, it sets the depth that triggers a clean and re-test. In the mixed roof spaces around Green Lanes and Palace Exchange, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Enfield run through existing hatches and new ones we cut, clean back to bright metal, take before-and-after grease-depth figures at set points, and certify it to TR19 Grease with those depths on the 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 Enfield hotels, care homes and gyms.
On the ground in Enfield
We are in Enfield's ductwork and plant every week. The proof is the jobs, not the stock photos.
A fast-food takeaway in Enfield had heavy congealed cooking oil and thick carbonised grease through the canopy plenum and extraction run. We hand-scraped the stubborn carbonised layers, worked a high-strength foaming degreaser through and wiped the lines down to bare metal for the TR19 standard. It was done on a late-night shift so the takeaway had no downtime.
When it is due
Ductwork rarely warns you politely. In a busy Enfield kitchen these are the tells.
A canopy dripping onto a Green Lanes cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or an Enfield insurer or fire risk assessor wanting a TR19 certificate you have not got. How often it needs doing follows how hard you cook - a fast-frying Church Street kitchen far more than a daytime cafe - and the certificate names the interval, so the next visit is booked, not guessed.
How it runs
Inspect the full Enfield 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 Palace Exchange 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 Enfield fire logbook.
Why it matters
Three duties push every Enfield 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 an Enfield 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 a Green Lanes 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 Enfield 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. Enfield Council food hygiene inspections assess the physical condition of premises, ventilation included. A grease-clogged system can count against the rating an Environmental Health Officer awards, quite apart from the smell and the falling extract performance your staff have to work in.
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 Green Lanes kitchen sits in a tighter band than a daytime Church Street cafe. We measure the grease load and confirm your interval.
We fit compliant access panels where the ductwork has none, so every internal section can be reached, cleaned, inspected and certified - common in the older Palace Exchange conversions where the run was boxed in with no hatches.
Yes - from Green Lanes and Church Street kitchens to the offices, schools and industrial units across Enfield and the wider Greater London.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Green Lanes operator's insurer and fire risk assessor expect.
The full run, canopy through the concealed horizontal and vertical ductwork to the roof fan - the hidden sections a canopy-only clean leaves loaded, which matters in the tight stock around Green Lanes and Palace Exchange where the runs are long and awkward.
Yes. We clean the dry ductwork and air-handling in Enfield offices, schools and public buildings, and the lint-heavy laundry ducts in the Greater London hotels and care homes, alongside kitchen grease ducts.
Little, if it is planned. We survey the Enfield run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Church Street cookline is back in service for the next shift.
