Portsmouth · 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 Portsmouth, and certify it to the TR19 Grease standard your insurer expects.
Portsmouth
Portsmouth rates around 1,830 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 Portsmouth, from Albert Road through Palmerston Road to Old Portsmouth, 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.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Portsmouth schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - the University of Portsmouth, Queen Alexandra Hospital, Fratton Park and the seafront hotels - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Portsmouth 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 Albert Road and Old Portsmouth, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Portsmouth 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 Portsmouth hotels, care homes and gyms.
On the ground in Portsmouth
We are in Portsmouth's ductwork and plant every week. The proof is the jobs, not the stock photos.
A coastal apartment block in Portsmouth had stagnant refuse blockages and decomposing waste fouling the lower five storeys of its vertical refuse chute. We ran a high-pressure hot-water rig with a motorised spinning nozzle from the top down and treated it with a bactericidal sanitiser, clearing the obstructions and sanitising the lining - working with the residents' association to keep every hopper door locked during the wash.
When it is due
Ductwork rarely warns you politely. In a busy Portsmouth kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto an Albert Road cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Portsmouth insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Palmerston Road kitchen needs it far more often than a daytime cafe - and your certificate states the interval, so the next clean is never a guess.
How it runs
Inspect the full Portsmouth 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 Old Portsmouth 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 Portsmouth fire logbook.
Why it matters
Three duties push every Portsmouth 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 Portsmouth 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 an Albert 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. A current TR19 Grease certificate is the evidence your Portsmouth 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. Food hygiene inspections by Portsmouth City Council take in the condition of the building, ventilation included, so a grease-laden system can cost you on the rating an Environmental Health Officer awards - never mind the smell and the dropping extraction your kitchen team works under.
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 Albert Road kitchen sits in a tighter band than a daytime Palmerston Road cafe. We measure the grease load and confirm your interval.
Yes. We clean the dry ductwork and air-handling in Portsmouth offices, schools and public buildings, and the lint-heavy laundry ducts in the Hampshire hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Albert Road and Palmerston Road kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Little, if it is planned. We survey the Portsmouth run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Palmerston Road cookline is back in service for the next shift.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence an Albert Road operator's insurer and fire risk assessor expect.
Yes - from Albert Road and Palmerston Road kitchens to the offices, schools and industrial units across Portsmouth 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 Albert Road and Old Portsmouth where the runs are long and awkward.
