Gloucester · 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 Gloucester, and certify it to the TR19 Grease standard your insurer expects.
Gloucester
Gloucester rates around 1,050 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 Gloucester, from Northgate Street through Westgate Street to Docks, 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.
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 Gloucestershire, the Gloucestershire Royal Hospital, Kingsholm and the quays hotels - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Gloucester 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 Northgate Street and Docks, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Gloucester 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 Gloucester hotels, care homes and gyms.
On the ground in Gloucester
We are in Gloucester's ductwork and plant every week. The proof is the jobs, not the stock photos.
A multi-storey office block in Gloucester had atmospheric dust, pollen and fine black particulate coating the inside of the supply-air ducts and plenums. We isolated the runs into zones, ran motorised rotary brushes through and vacuumed the debris out on a HEPA air mover, lifting the indoor-air-quality scores across the floors. We sourced a set of premium pleated filters for the on-site maintenance team to fit.
When it is due
Ductwork rarely warns you politely. In a busy Gloucester 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 Northgate Street line, grease crusting at the filter rims, or a Gloucester 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 Westgate 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 Gloucester 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 Docks 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 Gloucester 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 Gloucester 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 Northgate 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. To a Gloucester insurer a current TR19 Grease certificate is the proof the extract has been kept up. Let it lapse and a fire claim can be scaled back or declined outright - the kind of gap nobody wants to find with the kitchen already gutted.
Hygiene and environmental health. A food hygiene visit from Gloucester 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 Northgate Street kitchen sits in a tighter band than a daytime Westgate Street cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Gloucester run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Westgate Street 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 a Northgate Street operator's insurer and fire risk assessor expect.
Yes. We clean the dry ductwork and air-handling in Gloucester offices, schools and public buildings, and the lint-heavy laundry ducts in the Gloucestershire hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Northgate Street and Westgate Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes - from Northgate Street and Westgate Street kitchens to the offices, schools and industrial units across Gloucester and the wider Gloucestershire.
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 Docks conversions where the run was boxed in with no hatches.
