Inverness · 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 Inverness, and certify it to the TR19 Grease standard your insurer expects.
Inverness
Inverness 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.
The city's kitchens sit in tight, mixed stock - Church Street, Academy Street, Ness Bank - 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.
Beyond the kitchens, we clean the dry ductwork and air-handling in offices, schools and public buildings, and the lint-heavy laundry ducts in hotels and care homes. High-output kitchens - hotel kitchens, coach-tour caterers, hospital and college canteens and Old Town takeaways - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Inverness 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 Church Street and Ness Bank, 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 Inverness 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 Inverness hotels, care homes and gyms.
On the ground in Inverness
We are in Inverness's ductwork and plant every week. The proof is the jobs, not the stock photos.
An apartment block in Inverness had a refuse chute with a greasy film of rotting waste coating the inside from top to bottom. We power-washed the chute, cleared the hopper doors and applied an antibacterial treatment. The chute was sanitised from top to bottom and the stairwell was pleasant to use again, with the site left spotless.
When it is due
Ductwork rarely warns you politely. In a busy Inverness 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 Church Street line, grease crusting at the filter rims, or an Inverness 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 Academy 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 Inverness 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 Ness Bank conversions - and protect the kitchen.
Canopy to roof fan, down to bare metal, with before-and-after grease-depth evidence.

Why it matters
Three duties push every Inverness 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 an Inverness 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 Church 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 Inverness 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 Highland Council weighs the physical state of the premises, ventilation counted within it. A grease-blocked extract can pull down the result 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 Church Street kitchen sits in a tighter band than a daytime Academy 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 Ness Bank conversions where the run was boxed in with no hatches.
Little, if it is planned. We survey the Inverness run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so an Academy Street cookline is back in service for the next shift.
Yes. The fan at the top of a Ness Bank 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 - from Church Street and Academy Street kitchens to the offices, schools and industrial units across Inverness and the wider the Highlands.
Yes. We clean the dry ductwork and air-handling in Inverness offices, schools and public buildings, and the lint-heavy laundry ducts in the the Highlands hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Church Street and Academy Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Local knowledge
Thomas Telford's Caledonian Canal opened in 1822, threading Inverness to the west coast through a chain of locks that still lift boats above the town. Ductwork hides its own engineering the same way - out of sight until it silts up. We survey extract and supply ducting across Inverness to the TR19 Grease standard, photograph the inside, clean it back to bare metal where grease has built, and fit access panels so the next inspection is straightforward.
