Belper · 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 Belper, and certify it to the TR19 Grease standard your insurer expects.
Belper
Belper 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.
Right across Belper, from King Street through Campbell Street to Belper Lane, 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.
It is not only kitchens: we also clean the dry supply and extract ductwork in Belper offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - care-home kitchens, school canteens, pub and bistro kitchens and the busy town-centre takeaways - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Belper 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 King Street and Belper Lane, a canopy-and-filter wipe leaves the duct interior - where grease piles up and a fire runs - completely alone. We reach the whole Belper 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 Belper hotels, care homes and gyms.
On the ground in Belper
We are in Belper's ductwork and plant every week. The proof is the jobs, not the stock photos.
Heavy grease had collected along the horizontal duct run above the canopy at an independent pub kitchen in Belper, a clear fire risk. We cut in access doors, cleared the grease from the horizontal run and finished with a degreasing wash. The duct came up to bare metal and the fire risk was gone, with certification prepared for the client's file. We had it turned round within the day so the regulars barely noticed.
When it is due
Ductwork rarely warns you politely. In a busy Belper kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a King Street cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Belper insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Campbell Street kitchen needs it far more often than a daytime cafe - and your certificate states the interval, so the next clean is never a guess.
How it runs
Inspect the full Belper 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 Belper 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 Belper fire logbook.
Why it matters
Three duties push every Belper 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 Belper 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 King 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 Belper 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. When Amber Valley Borough Council carries out a food hygiene inspection it judges the physical state of the premises, and ventilation is part of that. A grease-choked extract can pull down the rating an Environmental Health Officer gives, on top of the odour and the weakening airflow your staff put up with.
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 King Street kitchen sits in a tighter band than a daytime Campbell Street cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Belper run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Campbell Street cookline is back in service for the next shift.
Yes - from King Street and Campbell Street kitchens to the offices, schools and industrial units across Belper and the wider Derbyshire.
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 King Street and Belper Lane 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 King Street operator's insurer and fire risk assessor expect.
Yes. We work overnight, early mornings and closing days for the King Street and Campbell Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes. We clean the dry ductwork and air-handling in Belper offices, schools and public buildings, and the lint-heavy laundry ducts in the Derbyshire hotels and care homes, alongside kitchen grease ducts.
Local knowledge
Jedediah Strutt raised his first cotton mill on the Derwent in 1776, and the fireproof North Mill his son William built in 1804 helped make Belper one of the birthplaces of the factory system, its floors once thick with airborne cotton lint. Modern premises hide their dust and grease inside sealed ductwork instead, where it builds unseen until airflow fails or fire finds a path. The red-brick East Mill of 1912 still towers over the town as a reminder of how much air those mills once moved. We clean and inspect ventilation and extract ductwork across Belper, then hand over photographic before-and-after evidence of every run.
