Plymouth · 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 Plymouth, and certify it to the TR19 Grease standard your insurer expects.
Plymouth
Plymouth rates around 1,860 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 - Mutley Plain, North Hill, Royal William Yard - 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 University of Plymouth, Derriford Hospital, Home Park and the waterfront hotels - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Plymouth 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 Mutley Plain and Royal William Yard, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Plymouth 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 Plymouth hotels, care homes and gyms.
On the ground in Plymouth
We are in Plymouth's ductwork and plant every week. The proof is the jobs, not the stock photos.
A public library and community centre in Plymouth had the ground-floor washroom extract grilles completely matted over with grey dust - no measurable extraction at all. We unclipped every grille for a deep sanitisation, brushed out the rectangular galvanised duct lines and cleared the main inline fan blades. The extraction came back across all the facilities - and we found an old bird's nest in the external discharge louvre, cleared it and fitted a new mesh bird screen.
When it is due
Ductwork rarely warns you politely. In a busy Plymouth kitchen these are the tells.
A canopy dripping onto a Mutley Plain cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Plymouth 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 North Hill 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 Plymouth 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 Royal William Yard 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 Plymouth fire logbook.
Why it matters
Three duties push every Plymouth 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 Plymouth 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 Mutley Plain 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 Plymouth 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. A food hygiene visit from Plymouth City 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 Mutley Plain kitchen sits in a tighter band than a daytime North Hill cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Plymouth run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a North Hill cookline is back in service for the next shift.
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 Royal William Yard conversions where the run was boxed in with no hatches.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Mutley Plain operator's insurer and fire risk assessor expect.
Yes. We work overnight, early mornings and closing days for the Mutley Plain and North Hill kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
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 Mutley Plain and Royal William Yard where the runs are long and awkward.
Yes - from Mutley Plain and North Hill kitchens to the offices, schools and industrial units across Plymouth and the wider Devon.
