Droitwich · 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 Droitwich, and certify it to the TR19 Grease standard your insurer expects.
Droitwich
Droitwich 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.
The city's kitchens sit in tight, mixed stock - Friar Street, Victoria Square, Dodderhill - with long concealed duct runs up to roof fans. We clean the full run to the TR19 Grease standard, canopy to fan, including the horizontal and vertical sections a canopy-only clean leaves coated.
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 - pub and hotel kitchens, care-home and school kitchens and the busy town-centre takeaways - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Droitwich 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 Friar Street and Dodderhill, 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 Droitwich 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 Droitwich hotels, care homes and gyms.
On the ground in Droitwich
We are in Droitwich's ductwork and plant every week. The proof is the jobs, not the stock photos.
At a town-centre Droitwich care home, the flexible dryer ducting was choked with fine textile lint, forcing the dryers to work far harder than they should. We cleared the ducting out, checked the run for damage and tested airflow at the discharge louvre. The dryers ran hotter and faster and the back room lost its damp, warm feel — the client booked us back in there and then.
When it is due
Ductwork rarely warns you politely. In a busy Droitwich kitchen these are the tells.
A canopy dripping onto a Friar Street cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Droitwich 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 Victoria Square 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 Droitwich 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 Dodderhill 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 Droitwich fire logbook.
Why it matters
Three duties push every Droitwich 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 Droitwich 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 Friar 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. Your Droitwich 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 Wychavon 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 Friar Street kitchen sits in a tighter band than a daytime Victoria Square cafe. We measure the grease load and confirm your interval.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Friar Street operator's insurer and fire risk assessor expect.
Yes. The fan at the top of a Dodderhill 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.
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 Friar Street and Dodderhill where the runs are long and awkward.
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 Dodderhill conversions where the run was boxed in with no hatches.
Little, if it is planned. We survey the Droitwich run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Victoria Square cookline is back in service for the next shift.
Yes - from Friar Street and Victoria Square kitchens to the offices, schools and industrial units across Droitwich and the wider Worcestershire.
Local knowledge
Corbett's brine was pumped from the springs and evaporated in vast open pans, and the Droitwich Barge Canal that James Brindley cut in 1771 carried the finished salt away by narrowboat. The evaporating houses and their sooty flues are long gone, and modern premises hide their dust inside sealed ductwork instead, where grease and debris build 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.
