Shaftesbury · 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 Shaftesbury, and certify it to the TR19 Grease standard your insurer expects.
Shaftesbury
Shaftesbury 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 Shaftesbury work out of tight, mixed premises - High Street, Bell Street, Angel 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.
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 - school refectories, hospital kitchens, pub carveries and the town's hotel and tearoom catering - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Shaftesbury 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 Angel Lane, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Shaftesbury 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 Shaftesbury hotels, care homes and gyms.
On the ground in Shaftesbury
We are in Shaftesbury's ductwork and plant every week. The proof is the jobs, not the stock photos.
A popular launderette in Shaftesbury had a season's worth of fibre lint built through the dryer exhaust ductwork, leaving the room warm and humid. We ran brushes and a HEPA vacuum through the extract ducting, then confirmed a clean discharge outside. Airflow through the line was restored and the external wall flap sat fully open again. Access was tight, so we loaded in through the back to reach the far end.
When it is due
Ductwork rarely warns you politely. In a busy Shaftesbury 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 Shaftesbury 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 Bell 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 Shaftesbury 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 Angel 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 Shaftesbury fire logbook.
Why it matters
Three duties push every Shaftesbury 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 Shaftesbury 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 Shaftesbury 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. Food hygiene inspections by Dorset Council take in the condition of the building, ventilation included, so a grease-laden system can cost you on the rating an Environmental Health Officer awards - never mind the smell and the dropping extraction your kitchen team works under.
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 Bell Street cafe. We measure the grease load and confirm your interval.
Yes. We clean the dry ductwork and air-handling in Shaftesbury offices, schools and public buildings, and the lint-heavy laundry ducts in the Dorset hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the High Street and Bell Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Little, if it is planned. We survey the Shaftesbury run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Bell Street cookline is back in service for the next shift.
Yes - from High Street and Bell Street kitchens to the offices, schools and industrial units across Shaftesbury and the wider Dorset.
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 Angel Lane where the runs are long and awkward.
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 Angel Lane conversions where the run was boxed in with no hatches.
Local knowledge
King Canute, ruler of England, Denmark and Norway, died in Shaftesbury in 1035 and his body was carried to Winchester for burial, a reminder that the hilltop town once stood near the centre of a North Sea empire. Reach and connection mattered then; ductwork is the same idea now. Above the town's kitchens and workshops, extract runs load unseen with grease and dust, and only opening, brushing and inspecting the full length to the TR19 standard shows what has really built up out of sight.
