Retford · 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 Retford, and certify it to the TR19 Grease standard your insurer expects.
Retford
Retford 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.
The city's kitchens sit in tight, mixed stock - Bridgegate, Grove Street, Chapelgate - with long concealed duct runs up to roof fans. We clean the full run to the TR19 Grease standard, canopy to fan, including the horizontal and vertical sections a canopy-only clean leaves coated.
It is not only kitchens: we also clean the dry supply and extract ductwork in Retford offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - hospital and care-home kitchens, pub and restaurant 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 Retford 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 Bridgegate and Chapelgate, 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 Retford 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 Retford hotels, care homes and gyms.
On the ground in Retford
We are in Retford's ductwork and plant every week. The proof is the jobs, not the stock photos.
Fine atmospheric dust had built up across the dry ventilation ducting and AHU of a privately owned library reading room in Retford. We put rotary brushes and a negative-air machine through the branch runs, then swapped out the dirty panel filters. Indoor air quality lifted across the open-plan space, and the client was really pleased with how quickly it was sorted. The site manager kept us going with a steady run of brews all morning.
When it is due
Ductwork rarely warns you politely. In a busy Retford kitchen these are the tells.
A canopy dripping onto a Bridgegate cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Retford insurer or fire risk assessor wanting a TR19 certificate you have not got. How often it needs doing follows how hard you cook - a fast-frying Grove Street kitchen far more than a daytime cafe - and the certificate names the interval, so the next visit is booked, not guessed.
How it runs
Inspect the full Retford 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 Chapelgate 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 Retford fire logbook.
Why it matters
Three duties push every Retford 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 Retford 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 Bridgegate 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. Your Retford insurer expects a current TR19 Grease certificate as proof the duct is clean. Without one, a fire claim can be cut back or turned down altogether - a costly thing to find only after a fire.
Hygiene and environmental health. Bassetlaw District 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 Bridgegate kitchen sits in a tighter band than a daytime Grove Street cafe. We measure the grease load and confirm your interval.
Yes. We clean the dry ductwork and air-handling in Retford offices, schools and public buildings, and the lint-heavy laundry ducts in the Nottinghamshire hotels and care homes, alongside kitchen grease ducts.
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 Chapelgate conversions where the run was boxed in with no hatches.
Little, if it is planned. We survey the Retford run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Grove Street cookline is back in service for the next shift.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Bridgegate 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 Bridgegate and Chapelgate where the runs are long and awkward.
Yes. The fan at the top of a Chapelgate 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.
Local knowledge
Retford grew rich on movement - the Great North Road turnpiked through in 1766, the Chesterfield Canal that James Brindley engineered reaching the town in 1777, and the railway arriving in 1849 to make it a junction on the East Coast Main Line. The mills, maltings and factories that clustered along the Idle and the canal ran their air through belts and flues, and modern premises hide their dust inside sealed ductwork instead, where grease and debris build unseen until airflow fails or fire finds a path. We clean and inspect ventilation and extract ductwork across the town, then hand over photographic before-and-after evidence of every run.
