Grimsby · 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 Grimsby, and certify it to the TR19 Grease standard your insurer expects.
Grimsby
Grimsby rates around 1,700 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 Freeman Street to Victoria Street and Kasbah, 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.
It is not only kitchens: we also clean the dry supply and extract ductwork in Grimsby offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - the Grimsby Institute, Diana, Princess of Wales Hospital, Blundell Park and the town hotels - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Grimsby insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard is written in film thickness: once grease reaches a set depth the run has to be cleaned and proven again. In the crowded roof voids off Freeman Street and Kasbah, a wipe of the canopy and filters never reaches the ductwork behind them, where the grease that carries fire quietly gathers. We work the whole Grimsby run through hatches already in place and others we cut, bring it back to bright metal, note grease depths at fixed stations before and after, and certify to TR19 Grease with the closing figures logged.
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 Grimsby hotels, care homes and gyms.
On the ground in Grimsby
We are in Grimsby's ductwork and plant every week. The proof is the jobs, not the stock photos.
A seafood-processing factory in Grimsby had coarse fabric dust and synthetic lint packing the shared laundry extraction riser and overloading the fan motor. We vacuumed the dryer exhaust plenums out, ran flexible push-rod brushes through the line and checked the external flap was operating, cutting the drying-cycle times and the energy use. The floor was on a light maintenance shift, so we could cordon our work zone off safely.
When it is due
Ductwork rarely warns you politely. In a busy Grimsby kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Freeman Street cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Grimsby insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Victoria 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 Grimsby 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 Kasbah 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 Grimsby fire logbook.
Why it matters
Three duties push every Grimsby 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 Grimsby 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 Freeman 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 Grimsby 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 North East Lincolnshire 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 Freeman Street kitchen sits in a tighter band than a daytime Victoria Street cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Grimsby run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Victoria 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 Freeman Street and Kasbah where the runs are long and awkward.
Yes. The fan at the top of a Kasbah 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 - from Freeman Street and Victoria Street kitchens to the offices, schools and industrial units across Grimsby and the wider Lincolnshire.
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 Kasbah conversions where the run was boxed in with no hatches.
Yes. We clean the dry ductwork and air-handling in Grimsby offices, schools and public buildings, and the lint-heavy laundry ducts in the Lincolnshire hotels and care homes, alongside kitchen grease ducts.
