Portishead · 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 Portishead, and certify it to the TR19 Grease standard your insurer expects.
Portishead
Portishead 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 Wyndham Way to Harbour Road and Slade Road, 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 - the marina restaurants, pub kitchens, care-home kitchens and busy town-centre takeaways - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Portishead insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Because the standard is written around film thickness, it sets the depth that triggers a clean and re-test. In the mixed roof spaces around Wyndham Way and Slade Road, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Portishead run through existing hatches and new ones we cut, clean back to bright metal, take before-and-after grease-depth figures at set points, and certify it to TR19 Grease with those depths on the record.
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 Portishead hotels, care homes and gyms.
On the ground in Portishead
We are in Portishead's ductwork and plant every week. The proof is the jobs, not the stock photos.
The reading-room supply ducting at a local Portishead library had collected fine grey dust and debris right across the runs and the ceiling diffusers. We cleaned the branch supply ducts with air whips under negative pressure and swapped out the dirty panel filters while we were in there. The supply air was back to a clean standard and the difference in the room was obvious straight away. We handed the office manager a short photo report to drop into their audit file.
When it is due
Ductwork rarely warns you politely. In a busy Portishead kitchen these are the tells.
A canopy dripping onto a Wyndham Way cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Portishead 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 Harbour Road 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 Portishead 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 Slade Road 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 Portishead fire logbook.
Why it matters
Three duties push every Portishead 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 Portishead 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 Wyndham Way 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. Your Portishead insurer expects a current TR19 Grease certificate as proof the duct is clean. Without one, a fire claim can be cut back or turned down altogether - a costly thing to find only after a fire.
Hygiene and environmental health. Food hygiene inspections by North Somerset 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 Wyndham Way kitchen sits in a tighter band than a daytime Harbour 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 Wyndham Way operator's insurer and fire risk assessor expect.
Yes. The fan at the top of a Slade Road 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.
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 Wyndham Way and Slade Road where the runs are long and awkward.
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 Slade Road conversions where the run was boxed in with no hatches.
Yes. We clean the dry ductwork and air-handling in Portishead offices, schools and public buildings, and the lint-heavy laundry ducts in the Somerset hotels and care homes, alongside kitchen grease ducts.
Little, if it is planned. We survey the Portishead run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Harbour Road cookline is back in service for the next shift.
Local knowledge
Portishead's deep-water dock opened in the 1870s to bring coal, timber and grain up the Bristol Channel, and a chemical works and the two power stations grew up around it, their air heavy with coal dust and fume. Modern premises hide their dust and grease inside sealed ductwork instead, where it builds unseen until airflow fails or fire finds a path. We clean and inspect ventilation and extract ductwork across the town, then hand over photographic before-and-after evidence of every run.
