Eltham · 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 Eltham, and certify it to the TR19 Grease standard your insurer expects.
Eltham
Eltham 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.
Right across Eltham, from High Street through Passey Place to Court Road, 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 Eltham offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - the University of Greenwich Avery Hill campus, the Eltham diagnostic centre, Eltham Palace 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 Eltham 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 Court Road, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Eltham 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 Eltham hotels, care homes and gyms.
On the ground in Eltham
We are in Eltham's ductwork and plant every week. The proof is the jobs, not the stock photos.
A primary school in Eltham had fine dust and loose insulation fibre settled through the classroom supply-air ducting over several terms. We ran mechanical power brushes and a high-efficiency negative-air unit through the lines to clear the loose debris, restoring clean air delivery ahead of the autumn term. It was all done over the summer holiday shutdown with the buildings empty.
When it is due
Ductwork rarely warns you politely. In a busy Eltham kitchen these are the tells.
Watch for steam that hangs in the room, cooking smells creeping back over the tables, a canopy weeping onto a High Street line, grease crusting at the filter rims, or an Eltham insurer or fire assessor calling for a TR19 certificate you do not hold. How often it needs doing rides on the cooking load - a hard-frying Passey Place kitchen far more than a quiet daytime cafe - and the certificate fixes that interval, so the next clean is planned, not chanced.
How it runs
Inspect the full Eltham 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 Court Road 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 Eltham fire logbook.
Why it matters
Three duties push every Eltham 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 Eltham 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 current TR19 Grease certificate is the evidence your Eltham 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. Royal Borough of Greenwich 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 High Street kitchen sits in a tighter band than a daytime Passey Place cafe. We measure the grease load and confirm your interval.
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 Court Road where the runs are long and awkward.
Yes. We work overnight, early mornings and closing days for the High Street and Passey Place kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes. The fan at the top of a Court Road 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 Eltham offices, schools and public buildings, and the lint-heavy laundry ducts in the Greater London hotels and care homes, alongside kitchen grease ducts.
Yes - from High Street and Passey Place kitchens to the offices, schools and industrial units across Eltham and the wider Greater London.
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 Court Road conversions where the run was boxed in with no hatches.
