Southampton · 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 Southampton, and certify it to the TR19 Grease standard your insurer expects.
Southampton
Southampton rates around 1,700 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 Southampton work out of tight, mixed premises - Bevois Valley, Oxford Street, Bedford Place - 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.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Southampton schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - the two universities, Southampton General Hospital, St Mary's Stadium and the city hotels - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Southampton 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 Bevois Valley and Bedford Place, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Southampton 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 Southampton hotels, care homes and gyms.
On the ground in Southampton
We are in Southampton's ductwork and plant every week. The proof is the jobs, not the stock photos.
A cruise-terminal catering kitchen in Southampton had the high-velocity canopy ducting lined with a thick, runny layer of cooking oil from constant high-volume service. We fitted liquid-tight collection funnels, sprayed an enzyme-based degreaser and squeegeed the horizontal runs clean, leaving the duct dry and safe. The whole thing had to fit into a tight window between ship dockings.
When it is due
Ductwork rarely warns you politely. In a busy Southampton kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Bevois Valley line, a rim of grease at the filters, or a Southampton insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Oxford Street 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 Southampton 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 Bedford Place conversions - and protect the kitchen.

Why it matters
Three duties push every Southampton 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 Southampton 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 Bevois Valley 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 Southampton 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. Southampton City Council 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 Bevois Valley kitchen sits in a tighter band than a daytime Oxford Street cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Southampton run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so an Oxford Street cookline is back in service for the next shift.
Yes. We work overnight, early mornings and closing days for the Bevois Valley and Oxford 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 Bedford Place conversions where the run was boxed in with no hatches.
Yes - from Bevois Valley and Oxford Street kitchens to the offices, schools and industrial units across Southampton and the wider Hampshire.
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 Bevois Valley and Bedford Place where the runs are long and awkward.
Yes. The fan at the top of a Bedford Place 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.
