Mansfield · 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 Mansfield, and certify it to the TR19 Grease standard your insurer expects.
Mansfield
Mansfield rates around 900 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 Mansfield work out of tight, mixed premises - Leeming Street, Market Place, Four Seasons - 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 - West Nottinghamshire College, King's Mill Hospital, the One Call Stadium and the town hotels - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Mansfield insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Grease is measured by thickness, and the standard sets the depth at which a system must be cleaned and re-tested. Around Leeming Street and Four Seasons, where the concealed runs thread through mixed roof voids, a canopy-and-filter wipe leaves the ductwork itself - the long hidden sections where grease accumulates and a fire travels - untouched. We access the full Mansfield run through existing and newly fitted inspection hatches, clean to bare metal, record before-and-after grease-depth readings at set points, and issue a TR19 Grease certificate with a post-clean depth 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 Mansfield hotels, care homes and gyms.
On the ground in Mansfield
We are in Mansfield's ductwork and plant every week. The proof is the jobs, not the stock photos.
A country pub kitchen in Mansfield had a thick, viscous layer of carbonised oil coating the main canopy plenum and the roof-mounted exhaust fan. We sheeted the kitchen off, worked a heavy-duty foaming degreaser through and hand-scraped the lines back to bare metal, clearing the fire risk off the cooking line. The historic layout ran an extra-long horizontal duct, so we fitted two new access doors to reach all of it.
When it is due
Ductwork rarely warns you politely. In a busy Mansfield kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Leeming Street line, a rim of grease at the filters, or a Mansfield insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Market Place 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 Mansfield 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 Four Seasons 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 Mansfield fire logbook.
Why it matters
Three duties push every Mansfield 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 Mansfield 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 Leeming 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 Mansfield 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. When Mansfield District 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 Leeming Street kitchen sits in a tighter band than a daytime Market Place cafe. We measure the grease load and confirm your interval.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Leeming Street operator's insurer and fire risk assessor expect.
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 Four Seasons conversions where the run was boxed in with no hatches.
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 Leeming Street and Four Seasons where the runs are long and awkward.
Yes. We clean the dry ductwork and air-handling in Mansfield offices, schools and public buildings, and the lint-heavy laundry ducts in the Nottinghamshire hotels and care homes, alongside kitchen grease ducts.
Little, if it is planned. We survey the Mansfield run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Market Place cookline is back in service for the next shift.
Yes - from Leeming Street and Market Place kitchens to the offices, schools and industrial units across Mansfield and the wider Nottinghamshire.
