Northampton · 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 Northampton, and certify it to the TR19 Grease standard your insurer expects.
Northampton
Northampton rates around 3,800 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 Northampton, from Wellingborough Road through St Giles Street to Abington Street, 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.
Beyond the kitchens, we clean the dry ductwork and air-handling in offices, schools and public buildings, and the lint-heavy laundry ducts in hotels and care homes. High-output kitchens - the University of Northampton, Northampton General Hospital, Sixfields and the town hotels - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Northampton insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard works in grease-film thickness, fixing the depth at which a run must be cleaned and re-tested. In the shared roof voids around Wellingborough Road and Abington Street, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Northampton run through existing and newly cut inspection hatches, strip it to bare metal, log grease-depth readings at fixed points before and after, and issue a TR19 Grease certificate with the post-clean depths recorded.
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 Northampton hotels, care homes and gyms.
On the ground in Northampton
We are in Northampton's ductwork and plant every week. The proof is the jobs, not the stock photos.
An Italian family restaurant in Northampton had carbonised fat and sticky oil lining the main canopy plenum and the horizontal fan housing. We fitted three liquid-tight fire-rated access hatches, scraped the hardened grease off by hand and treated the system with a caustic-free degreaser, certifying it to TR19. We checked the external ductwork early, before the chefs came in for the day.
When it is due
Ductwork rarely warns you politely. In a busy Northampton kitchen these are the tells.
A canopy dripping onto a Wellingborough Road cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Northampton 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 St Giles 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 Northampton 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 Abington Street conversions - and protect the kitchen.

Why it matters
Three duties push every Northampton 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 Northampton 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 Wellingborough Road 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 Northampton 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. Food hygiene inspections by West Northamptonshire 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 Wellingborough Road kitchen sits in a tighter band than a daytime St Giles Street cafe. We measure the grease load and confirm your interval.
Yes - from Wellingborough Road and St Giles Street kitchens to the offices, schools and industrial units across Northampton and the wider Northamptonshire.
Yes. The fan at the top of an Abington Street 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.
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 Abington Street 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 Wellingborough Road and Abington Street where the runs are long and awkward.
Yes. We work overnight, early mornings and closing days for the Wellingborough Road and St Giles Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Little, if it is planned. We survey the Northampton run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a St Giles Street cookline is back in service for the next shift.
