Brentwood · 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 Brentwood, and certify it to the TR19 Grease standard your insurer expects.
Brentwood
Brentwood 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.
From High Street to Crown Street and Pilgrims Hatch, the town's cooklines vent through long hidden ducting that climbs to a roof fan. We clean it end to end to the TR19 Grease standard - not just the canopy, but the flat and rising sections where grease really collects.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Brentwood schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - hotel and pub kitchens, the High Street restaurants, chicken shops and the busy takeaways - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Brentwood insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard works in grease-film thickness, fixing the depth at which a run must be cleaned and re-tested. In the shared roof voids around High Street and Pilgrims Hatch, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Brentwood run through existing and newly cut inspection hatches, strip it to bare metal, log grease-depth readings at fixed points before and after, and issue a TR19 Grease certificate with the post-clean depths recorded.
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 Brentwood hotels, care homes and gyms.
On the ground in Brentwood
We are in Brentwood's ductwork and plant every week. The proof is the jobs, not the stock photos.
A family-owned pub in Brentwood had a heavy build-up of grease along the extract duct running above the kitchen canopy, a clear fire risk. We scraped and degreased the horizontal run back to bare metal and gave the fryers a clean while we were in there. The duct was left spotless and fire-safe, with full documentation for their records. Staff were between jobs and happily worked around us.
When it is due
Ductwork rarely warns you politely. In a busy Brentwood kitchen these are the tells.
A canopy dripping onto a High Street cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Brentwood 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 Crown 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 Brentwood 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 Pilgrims Hatch 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 Brentwood fire logbook.
Why it matters
Three duties push every Brentwood 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 Brentwood 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 High Street 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 live TR19 Grease certificate is what a Brentwood insurer treats as evidence the system is maintained. Miss it and a fire claim may be reduced or refused - an expensive surprise once the damage is done.
Hygiene and environmental health. Food hygiene inspections by Brentwood Borough Council take in the condition of the building, ventilation included, so a grease-laden system can cost you on the rating an Environmental Health Officer awards - never mind the smell and the dropping extraction your kitchen team works under.
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 High Street kitchen sits in a tighter band than a daytime Crown Street cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Brentwood run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Crown Street cookline is back in service for the next shift.
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 High Street and Pilgrims Hatch where the runs are long and awkward.
Yes. The fan at the top of a Pilgrims Hatch 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 - from High Street and Crown Street kitchens to the offices, schools and industrial units across Brentwood and the wider Essex.
Yes. We work overnight, early mornings and closing days for the High Street and Crown Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a High Street operator's insurer and fire risk assessor expect.
Local knowledge
Brentwood grew as a coaching stop on the old London-to-Colchester road, but it was the Great Eastern main line, which reached the town in 1840, that turned it into a commuter and light-industrial centre. Its workshops now cluster on the estates at Childerditch, Hutton and West Horndon, and those modern units hide their dust inside sealed ductwork rather than venting it into the open air. There grease and debris build unseen until airflow fails or fire finds a path. We clean and inspect ventilation and extract ductwork across the town, then hand over photographic before-and-after evidence of every run.
