Perth · 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 Perth, and certify it to the TR19 Grease standard your insurer expects.
Perth
Perth 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.
Kitchens across Perth work out of tight, mixed premises - High Street, South Street, Princes Street - 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 Perth schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - hotel kitchens, college and hospital canteens, and the High Street takeaways - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Perth insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard is written in film thickness: once grease reaches a set depth the run has to be cleaned and proven again. In the crowded roof voids off High Street and Princes Street, a wipe of the canopy and filters never reaches the ductwork behind them, where the grease that carries fire quietly gathers. We work the whole Perth run through hatches already in place and others we cut, bring it back to bright metal, note grease depths at fixed stations before and after, and certify to TR19 Grease with the closing figures logged.
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 Perth hotels, care homes and gyms.
On the ground in Perth
We are in Perth's ductwork and plant every week. The proof is the jobs, not the stock photos.
An office suite in Perth had dry supply ducting that, behind the grilles, was thick with dust and debris, leaving dry eyes and stale air through the work areas. We isolated the zones, brushed out the internal ducting and washed the fan coil unit. Indoor air quality improved across the occupied areas, with the supply system left clean and moving air properly again.
When it is due
Ductwork rarely warns you politely. In a busy Perth kitchen these are the tells.
Watch for steam that hangs in the room, cooking smells creeping back over the tables, a canopy weeping onto a High Street line, grease crusting at the filter rims, or a Perth insurer or fire assessor calling for a TR19 certificate you do not hold. How often it needs doing rides on the cooking load - a hard-frying South Street kitchen far more than a quiet daytime cafe - and the certificate fixes that interval, so the next clean is planned, not chanced.
How it runs
Inspect the full Perth 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 Princes Street 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 Perth fire logbook.
Why it matters
Three duties push every Perth operator to keep ductwork clean, and they reinforce one another.
Fire safety law. Under the Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006, the duty-holder for a Perth 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 High Street 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 Perth 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. When Perth and Kinross Council 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 result 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 High Street kitchen sits in a tighter band than a daytime South Street cafe. We measure the grease load and confirm your interval.
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 Princes Street 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 High Street operator's insurer and fire risk assessor expect.
Yes. The fan at the top of a Princes Street 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.
Yes. We clean the dry ductwork and air-handling in Perth offices, schools and public buildings, and the lint-heavy laundry ducts in the Perth and Kinross hotels and care homes, alongside kitchen grease ducts.
Little, if it is planned. We survey the Perth run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a South Street cookline is back in service for the next shift.
Yes - from High Street and South Street kitchens to the offices, schools and industrial units across Perth and the wider Perth and Kinross.
Local knowledge
St John's Kirk still stands at the heart of the old town, where John Knox preached his firebrand sermon in 1559 and helped set the Scottish Reformation alight - Perth took its old name, St John's Toun, from the church. History clings to these streets, but grease clings harder inside kitchen ductwork. We clean extract systems from canopy to fan to roof outlet, in line with the current TR19 Grease standard, and issue photographic before-and-after evidence for your insurers.
