Croydon · 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 Croydon, and certify it to the TR19 Grease standard your insurer expects.
Croydon
Croydon rates around 3,000 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 - South End, Surrey Street, Purley - 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.
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 - the London South Bank University Croydon campus, Croydon University Hospital, Selhurst Park and the borough hotels - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Croydon 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 South End and Purley, 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 Croydon 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 Croydon hotels, care homes and gyms.
On the ground in Croydon
We are in Croydon's ductwork and plant every week. The proof is the jobs, not the stock photos.
A retail shopping centre in Croydon had a heavy load of atmospheric particulate and fine black dust through the main mall supply-air plenums and distribution branches. We isolated the duct networks, worked motorised rotary power brushes through and fitted fresh multi-pocket pleated filters in the air handling unit, lifting the air quality across the public concourse. All the pneumatic brushing was done overnight so there was no noise or dust during trading hours.
When it is due
Ductwork rarely warns you politely. In a busy Croydon 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 South End line, grease crusting at the filter rims, or a Croydon 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 Surrey Street 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 Croydon 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 Purley 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 Croydon fire logbook.
Why it matters
Three duties push every Croydon 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 Croydon 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 South End 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 Croydon 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 Croydon 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 South End kitchen sits in a tighter band than a daytime Surrey Street cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Croydon run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Surrey Street cookline is back in service for the next shift.
Yes - from South End and Surrey Street kitchens to the offices, schools and industrial units across Croydon and the wider Greater London.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a South End operator's insurer and fire risk assessor expect.
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 Purley conversions where the run was boxed in with no hatches.
Yes. We work overnight, early mornings and closing days for the South End and Surrey Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes. We clean the dry ductwork and air-handling in Croydon offices, schools and public buildings, and the lint-heavy laundry ducts in the Greater London hotels and care homes, alongside kitchen grease ducts.
