Northwich · 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 Northwich, and certify it to the TR19 Grease standard your insurer expects.
Northwich
Northwich 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.
From Witton Street to High Street and Church Road, the town's cooklines vent through long hidden ducting that climbs to a roof fan. We clean it end to end to the TR19 Grease standard - not just the canopy, but the flat and rising sections where grease really collects.
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 local college, the Victoria Infirmary, the Apple Market and the town hotels - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Northwich 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 Witton Street and Church Road, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Northwich 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 Northwich hotels, care homes and gyms.
On the ground in Northwich
We are in Northwich's ductwork and plant every week. The proof is the jobs, not the stock photos.
A Witton Street restaurant in Northwich had a heavy grease film through the horizontal extract and up the riser above a busy cook line. We fitted new access panels, hand-scraped the accessible lengths and ran an enzyme degreaser through the sealed sections, returning the ductwork to clean metal for the fire and insurance standard. It was worked overnight so the town-centre trade lost no covers.
When it is due
Ductwork rarely warns you politely. In a busy Northwich kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a Witton Street line, a rim of grease at the filters, or a Northwich insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying High Street 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 Northwich 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 Church Road conversions - and protect the kitchen.
Canopy to roof fan, down to bare metal, with before-and-after grease-depth evidence.

Why it matters
Three duties push every Northwich 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 Northwich 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 Witton 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 Northwich 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 Cheshire West and Chester 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 Witton Street kitchen sits in a tighter band than a daytime High Street cafe. We measure the grease load and confirm your interval.
Yes. We clean the dry ductwork and air-handling in Northwich offices, schools and public buildings, and the lint-heavy laundry ducts in the Cheshire hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Witton Street and High Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
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 Church Road conversions where the run was boxed in with no hatches.
Little, if it is planned. We survey the Northwich run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a High 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 Witton Street and Church Road where the runs are long and awkward.
Yes - from Witton Street and High Street kitchens to the offices, schools and industrial units across Northwich and the wider Cheshire.
