Maltby · 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 Maltby, and certify it to the TR19 Grease standard your insurer expects.
Maltby
Maltby rates well over a hundred 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 Maltby work out of tight, mixed premises - Muglet Lane, Grange Lane, Bramley - 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.
It is not only kitchens: we also clean the dry supply and extract ductwork in Maltby offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - academy and care-home kitchens, pub and hotel kitchens and the busy High Street takeaways - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Maltby 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 Muglet Lane and Bramley, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Maltby 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 Maltby hotels, care homes and gyms.
On the ground in Maltby
We are in Maltby's ductwork and plant every week. The proof is the jobs, not the stock photos.
Fine dust and debris had built up across the main supply runs and the AHU serving a busy Maltby library reading room. I worked through the supply ducting with brushes and HEPA extraction, then cleaned and refitted the grilles. Indoor air quality picked up across the work areas, and the difference was obvious straight away. I timed the visit for the school holidays while the place was quiet.
When it is due
Ductwork rarely warns you politely. In a busy Maltby kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Muglet Lane line, a rim of grease at the filters, or a Maltby insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Grange Lane 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 Maltby 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 Bramley 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 Maltby fire logbook.
Why it matters
Three duties push every Maltby 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 Maltby 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 Muglet Lane 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 Maltby 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. Food hygiene inspections by Rotherham Metropolitan Borough 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 Muglet Lane kitchen sits in a tighter band than a daytime Grange Lane cafe. We measure the grease load and confirm your interval.
Yes. The fan at the top of a Bramley 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.
Little, if it is planned. We survey the Maltby run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Grange Lane cookline is back in service for the next shift.
Yes - from Muglet Lane and Grange Lane kitchens to the offices, schools and industrial units across Maltby and the wider South Yorkshire.
Yes. We clean the dry ductwork and air-handling in Maltby offices, schools and public buildings, and the lint-heavy laundry ducts in the South Yorkshire hotels and care homes, alongside kitchen grease ducts.
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 Muglet Lane and Bramley where the runs are long and awkward.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Muglet Lane operator's insurer and fire risk assessor expect.
Local knowledge
Maltby Main was a deep, gassy pit, and keeping it safe meant forcing huge volumes of air down the shafts and through miles of underground roadways to clear firedamp and coal dust before it could ignite. Modern premises hide their dust and grease inside sealed ductwork instead, where it builds unseen until airflow fails or fire finds a path. We clean and inspect ventilation and extract ductwork across Maltby, from the units off Muglet Lane to the workshops around Grange Lane, then hand over photographic before-and-after evidence of every run. What the colliery managed in the open air, we manage inside the ducts.
