Stamford · 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 Stamford, and certify it to the TR19 Grease standard your insurer expects.
Stamford
Stamford 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.
Kitchens across Stamford work out of tight, mixed premises - Broad Street, St Marys Street, Barn Hill - 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 - coaching-inn and hotel kitchens, pub and restaurant kitchens, school and college refectories and the busy town-centre takeaways - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Stamford 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 Broad Street and Barn Hill, 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 Stamford 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 Stamford hotels, care homes and gyms.
On the ground in Stamford
We are in Stamford's ductwork and plant every week. The proof is the jobs, not the stock photos.
Dust and debris had gathered in the branch ducts feeding the rooms at an independent GP surgery in Stamford, leaving the air stale and warm. We ran rotary brushes and a negative-air machine through the branch runs, then fitted new AHU panel filters. Airflow returned to spec with the system left visibly clean, and the team were glad to finally have it dealt with. We left images from either side of the clean and a test report for the audit file.
When it is due
Ductwork rarely warns you politely. In a busy Stamford kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Broad Street cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Stamford insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying St Marys 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 Stamford 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 Barn Hill 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 Stamford fire logbook.
Why it matters
Three duties push every Stamford 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 Stamford 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 Broad 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 live TR19 Grease certificate is what a Stamford 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 South Kesteven District 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 Broad Street kitchen sits in a tighter band than a daytime St Marys Street cafe. We measure the grease load and confirm your interval.
Yes - from Broad Street and St Marys Street kitchens to the offices, schools and industrial units across Stamford and the wider Lincolnshire.
Yes. The fan at the top of a Barn Hill 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.
Yes. We clean the dry ductwork and air-handling in Stamford offices, schools and public buildings, and the lint-heavy laundry ducts in the Lincolnshire hotels and care homes, alongside kitchen grease ducts.
Little, if it is planned. We survey the Stamford run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a St Marys Street cookline is back in service for the next shift.
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 Broad Street and Barn Hill 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 Broad Street operator's insurer and fire risk assessor expect.
Local knowledge
The little steam-powered brewery at 21 All Saints Street, worked by Melbourn Brothers in the shadow of the fourteenth-century All Saints church, still turns a Victorian engine that once pumped liquor and dried casks in air thick with malt dust. Modern premises hide that kind of 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 the town, then hand over photographic before-and-after evidence of every run.
