Lewisham · 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 Lewisham, and certify it to the TR19 Grease standard your insurer expects.
Lewisham
Lewisham 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.
Right across Lewisham, from Lewisham High Street through Deptford High Street to Honor Oak, 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.
It is not only kitchens: we also clean the dry supply and extract ductwork in Lewisham offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - Goldsmiths University, University Hospital Lewisham, the Lewisham Shopping Centre 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 Lewisham 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 Lewisham High Street and Honor Oak, 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 Lewisham 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 Lewisham hotels, care homes and gyms.
On the ground in Lewisham
We are in Lewisham's ductwork and plant every week. The proof is the jobs, not the stock photos.
A council housing estate in Lewisham had flattened cardboard and heavy refuse sacks jammed between the third and fourth floors of its communal chute, throwing off a strong smell. We broke the obstruction down with industrial breakdown poles and ran an intensive chemical wash-down, restoring the gravity transit to the ground-floor compactor. We fitted a new heavy rubber draft-exclusion flap at the base to seal the bin-store odour out.
When it is due
Ductwork rarely warns you politely. In a busy Lewisham kitchen these are the tells.
A canopy dripping onto a Lewisham 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 Lewisham 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 Deptford High 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 Lewisham 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 Honor Oak conversions - and protect the kitchen.
Canopy to roof fan, down to bare metal, with before-and-after grease-depth evidence.

Why it matters
Three duties push every Lewisham 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 Lewisham 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 Lewisham 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 Lewisham 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. A food hygiene visit from Lewisham Council weighs the physical state of the premises, ventilation counted within it. A grease-blocked extract can pull down the rating an Environmental Health Officer sets, quite apart from the stale smell and the tired airflow your staff work beneath all shift.
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 Lewisham High Street kitchen sits in a tighter band than a daytime Deptford High Street cafe. We measure the grease load and confirm your interval.
Yes. The fan at the top of a Honor Oak 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 work overnight, early mornings and closing days for the Lewisham High Street and Deptford High Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
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 Honor Oak conversions where the run was boxed in with no hatches.
Yes. We clean the dry ductwork and air-handling in Lewisham 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 Lewisham run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Deptford High 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 Lewisham High Street and Honor Oak where the runs are long and awkward.
