Marlborough · 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 Marlborough, and certify it to the TR19 Grease standard your insurer expects.
Marlborough
Marlborough rates dozens 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 Marlborough work out of tight, mixed premises - High Street, Kingsbury Street, George Lane - 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 Marlborough schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - pub carveries, the college refectory and the High Street restaurants - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Marlborough insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard works in grease-film thickness, fixing the depth at which a run must be cleaned and re-tested. In the shared roof voids around High Street and George Lane, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Marlborough run through existing and newly cut inspection hatches, strip it to bare metal, log grease-depth readings at fixed points before and after, and issue a TR19 Grease certificate with the post-clean depths recorded.
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 Marlborough hotels, care homes and gyms.
On the ground in Marlborough
We are in Marlborough's ductwork and plant every week. The proof is the jobs, not the stock photos.
A family-owned holiday-park laundry block in Marlborough had compacted fine textile lint lining the full length of the exhaust ductwork, with the external wall flap barely moving. We cleared the run of lint, checked it for damage and tested airflow at the wall flap. The system ran cooler and cleaner and the flap opened fully once more, with the block left tidy afterwards.
When it is due
Ductwork rarely warns you politely. In a busy Marlborough kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a High Street line, a rim of grease at the filters, or a Marlborough insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Kingsbury Street kitchen needs it far more often than a quiet cafe - and your certificate sets the date, so nothing is left to chance.
How it runs
Inspect the full Marlborough 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 George Lane 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 Marlborough fire logbook.
Why it matters
Three duties push every Marlborough 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 Marlborough 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 live TR19 Grease certificate is what a Marlborough insurer treats as evidence the system is maintained. Miss it and a fire claim may be reduced or refused - an expensive surprise once the damage is done.
Hygiene and environmental health. Wiltshire Council food hygiene inspections assess the physical condition of premises, ventilation included. A grease-clogged system can count against the rating an Environmental Health Officer awards, quite apart from the smell and the falling extract performance your staff have to work in.
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 Kingsbury Street cafe. We measure the grease load and confirm your interval.
Yes. We clean the dry ductwork and air-handling in Marlborough offices, schools and public buildings, and the lint-heavy laundry ducts in the Wiltshire hotels and care homes, alongside kitchen grease ducts.
Yes. The fan at the top of a George Lane 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.
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.
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 High Street and George Lane where the runs are long and awkward.
Little, if it is planned. We survey the Marlborough run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Kingsbury Street cookline is back in service for the next shift.
Yes. We work overnight, early mornings and closing days for the High Street and Kingsbury Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Local knowledge
Marlborough College opened in 1843 to educate the sons of clergy and now schools around 1,000 pupils, the Princess of Wales among its former pupils. A campus that size runs a great deal of ductwork - kitchens, science blocks, boarding houses - and grease and dust build inside it out of sight. We clean extract ductwork across the town to the TR19 grease standard, measuring deposit before and after so the fire risk in the hidden runs is genuinely removed.
