Sutton · 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 Sutton, and certify it to the TR19 Grease standard your insurer expects.
Sutton
Sutton rates around 1,300 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.
Kitchens across Sutton work out of tight, mixed premises - Cheam Village, Times Square, Worcester Park - their extract snaking through concealed voids to roof-mounted fans. We take the whole run to the TR19 Grease standard, hood to fan, reaching the horizontal legs and vertical risers a canopy wipe never touches.
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 Institute of Cancer Research, the Royal Marsden Hospital, the Times Square centre and the borough hotels - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Sutton 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 Cheam Village and Worcester Park, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Sutton 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 Sutton hotels, care homes and gyms.
On the ground in Sutton
We are in Sutton's ductwork and plant every week. The proof is the jobs, not the stock photos.
A high-street department-store restaurant in Sutton had a dense grease layer through the horizontal extract and up the roof riser above the kitchen. We fitted access hatches along the concealed run, hand-scraped the heavy grease and ran an enzyme treatment through the sealed sections, bringing the ductwork to clean metal for the fire and insurance standard. The work was done through the night after the store closed.
When it is due
Ductwork rarely warns you politely. In a busy Sutton kitchen these are the tells.
A canopy dripping onto a Cheam Village cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Sutton 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 Times Square 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 Sutton 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 Worcester Park 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 Sutton 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 Sutton 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 Cheam Village 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 Sutton 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. When London Borough of Sutton carries out a food hygiene inspection it judges the physical state of the premises, and ventilation is part of that. A grease-choked extract can pull down the rating an Environmental Health Officer gives, on top of the odour and the weakening airflow your staff put up with.
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 Cheam Village kitchen sits in a tighter band than a daytime Times Square cafe. We measure the grease load and confirm your interval.
Yes. The fan at the top of a Worcester Park 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 Worcester Park conversions where the run was boxed in with no hatches.
Yes. We work overnight, early mornings and closing days for the Cheam Village and Times Square 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 Sutton offices, schools and public buildings, and the lint-heavy laundry ducts in the south London hotels and care homes, alongside kitchen grease ducts.
Yes - from Cheam Village and Times Square kitchens to the offices, schools and industrial units across Sutton and the wider south London.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Cheam Village operator's insurer and fire risk assessor expect.
