Leicester · 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 Leicester, and certify it to the TR19 Grease standard your insurer expects.
Leicester
Leicester rates around 3,275 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 Belgrave Road to London Road and Frog Island, 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 Leicester offices, schools and public buildings, and the lint-packed laundry runs behind its hotel and care-home dryers. The busiest kitchens - the two universities, the Leicester Royal Infirmary, King Power Stadium and Welford Road and the city hotels - coat their hidden ducting in grease quickest, and that is the very path a fire follows.
The standard
TR19 Grease is the benchmark Leicester 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 Belgrave Road and Frog Island, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Leicester 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 Leicester hotels, care homes and gyms.
On the ground in Leicester
We are in Leicester's ductwork and plant every week. The proof is the jobs, not the stock photos.
An Indian buffet restaurant in Leicester had deep, viscous layers of spiced cooking oil sitting in the low points of the horizontal extract ductwork. We set up chemical containment, sprayed a high-strength foam degreaser and scraped the lines back to bare metal before pressure-rinsing. It passed a grease-thickness test with nothing left in the run - and we found an old access door leaking grease onto a false ceiling and swapped it for a liquid-tight insulated hatch.
When it is due
Ductwork rarely warns you politely. In a busy Leicester kitchen these are the tells.
Watch for steam that hangs in the room, cooking smells creeping back over the tables, a canopy weeping onto a Belgrave Road line, grease crusting at the filter rims, or a Leicester insurer or fire assessor calling for a TR19 certificate you do not hold. How often it needs doing rides on the cooking load - a hard-frying London Road kitchen far more than a quiet daytime cafe - and the certificate fixes that interval, so the next clean is planned, not chanced.
How it runs
Inspect the full Leicester 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 Frog Island 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 Leicester fire logbook.
Why it matters
Three duties push every Leicester 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 Leicester 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 Belgrave 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. A live TR19 Grease certificate is what a Leicester 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 Leicester City 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 Belgrave Road kitchen sits in a tighter band than a daytime London Road cafe. We measure the grease load and confirm your interval.
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 Frog Island conversions where the run was boxed in with no hatches.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Belgrave Road operator's insurer and fire risk assessor expect.
Little, if it is planned. We survey the Leicester run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a London Road cookline is back in service for the next shift.
Yes. The fan at the top of a Frog Island 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 work overnight, early mornings and closing days for the Belgrave Road and London Road kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes. We clean the dry ductwork and air-handling in Leicester offices, schools and public buildings, and the lint-heavy laundry ducts in the East Midlands hotels and care homes, alongside kitchen grease ducts.
