Woolwich · 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 Woolwich, and certify it to the TR19 Grease standard your insurer expects.
Woolwich
Woolwich rates around 2,300 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.
The city's kitchens sit in tight, mixed stock - Powis Street, Hare Street, Royal Arsenal - with long concealed duct runs up to roof fans. We clean the full run to the TR19 Grease standard, canopy to fan, including the horizontal and vertical sections a canopy-only clean leaves coated.
It is not only kitchens: we also clean the dry supply and extract ductwork in Woolwich offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - the Queen Elizabeth Hospital, the Royal Arsenal Riverside, the Woolwich Works and the local hotels - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Woolwich insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard is written in film thickness: once grease reaches a set depth the run has to be cleaned and proven again. In the crowded roof voids off Powis Street and Royal Arsenal, a wipe of the canopy and filters never reaches the ductwork behind them, where the grease that carries fire quietly gathers. We work the whole Woolwich run through hatches already in place and others we cut, bring it back to bright metal, note grease depths at fixed stations before and after, and certify to TR19 Grease with the closing figures logged.
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 Woolwich hotels, care homes and gyms.
On the ground in Woolwich
We are in Woolwich's ductwork and plant every week. The proof is the jobs, not the stock photos.
A buffet restaurant in Woolwich town centre had thick, sticky oxidised grease and heavy oil vapour settled across the canopy plenum and the main fan impeller. We hand-scraped the heavy crusts off, worked a specialist alkaline gel through and wet-wiped the extractor fan clean, restoring the extraction and dropping the fan noise for the insurance standard. It was worked overnight so the daily trade was undisturbed.
When it is due
Ductwork rarely warns you politely. In a busy Woolwich kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Powis Street cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Woolwich insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Hare Street kitchen needs it far more often than a daytime cafe - and your certificate states the interval, so the next clean is never a guess.
How it runs
Inspect the full Woolwich 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 Royal Arsenal 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 Woolwich fire logbook.
Why it matters
Three duties push every Woolwich 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 Woolwich 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 Powis 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. To a Woolwich insurer a current TR19 Grease certificate is the proof the extract has been kept up. Let it lapse and a fire claim can be scaled back or declined outright - the kind of gap nobody wants to find with the kitchen already gutted.
Hygiene and environmental health. Food hygiene inspections by Royal Borough of Greenwich 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 Powis Street kitchen sits in a tighter band than a daytime Hare Street cafe. We measure the grease load and confirm your interval.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Powis Street operator's insurer and fire risk assessor expect.
Yes. We work overnight, early mornings and closing days for the Powis Street and Hare Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes - from Powis Street and Hare Street kitchens to the offices, schools and industrial units across Woolwich and the wider Greater London.
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 Powis Street and Royal Arsenal where the runs are long and awkward.
Yes. The fan at the top of a Royal Arsenal 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.
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 Royal Arsenal conversions where the run was boxed in with no hatches.
