Sidcup · 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 Sidcup, and certify it to the TR19 Grease standard your insurer expects.
Sidcup
Sidcup 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 Hadlow Road to Longlands Road and Lamorbey, 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.
The same crews clean dry ventilation and air-handling ductwork in offices, schools and civic buildings, plus the combustible lint runs behind hotel and care-home dryers. High-turnover sites - hospital kitchens, college refectories, pub and restaurant kitchens and the busy High Street takeaways - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Sidcup 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 Hadlow Road and Lamorbey, 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 Sidcup 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 Sidcup hotels, care homes and gyms.
On the ground in Sidcup
We are in Sidcup's ductwork and plant every week. The proof is the jobs, not the stock photos.
A high-street bakery-cafe in Sidcup ran a combi oven and a flat griddle whose shared extract climbed a concealed chase in the party wall, and years of unburnt fat had set to a tar-like glaze along the whole rise. We opened the chase at each floor, chiselled the hardened glaze off the seams and flue spigots, then washed the run down with a hot alkaline gel until the steel showed bright and met the TR19 grease standard. The draw at the hood came back strong on the manometer, a witness swab wiped clean, and the bakery kept its counter open at the front while we worked the back of house. Because the chase was shared with the flat above, we boxed and taped the openings before cutting to keep dust off the tenant landing, drew the waste into lidded drums, and refitted each hatch with a fresh intumescent seal so the party wall held its fire rating. A follow-up interval was pencilled against the certificate to match the oven daily hours, and the counter staff barely registered the crew behind the serving hatch.
When it is due
Ductwork rarely warns you politely. In a busy Sidcup kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Hadlow Road line, a rim of grease at the filters, or a Sidcup insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Longlands Road kitchen needs it far more often than a quiet cafe - and your certificate sets the date, so nothing is left to chance.
How it runs
Inspect the full Sidcup 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 Lamorbey 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 Sidcup fire logbook.
Why it matters
Three duties push every Sidcup 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 Sidcup 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 Hadlow Road 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 Sidcup 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. A food hygiene visit from London Borough of Bexley 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 Hadlow Road kitchen sits in a tighter band than a daytime Longlands Road 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 Hadlow Road 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 Hadlow Road and Lamorbey where the runs are long and awkward.
Yes. The fan at the top of a Lamorbey 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 Sidcup 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 Hadlow Road and Longlands Road kitchens to the offices, schools and industrial units across Sidcup 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 Lamorbey conversions where the run was boxed in with no hatches.
Local knowledge
When the railway reached Sidcup in 1866 it turned a scatter of farmland and the old village of Foots Cray into a working commuter suburb, and trade units and factories followed the line and the A20. The premises that stand on those estates today hide their dust and grease inside sealed ductwork rather than in open mill air. Left alone, that build-up gathers unseen until airflow fails or fire finds a path along the run. We clean and inspect ventilation and extract ductwork across the town, then hand over photographic before-and-after evidence of every section.
