Guildford · 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 Guildford, and certify it to the TR19 Grease standard your insurer expects.
Guildford
Guildford rates around 1,100 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 Tunsgate Quarter to North Street and Guildford Wharf, 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.
Kitchens are only half the work - we also strip the dry supply and extract ductwork of Guildford schools, offices and civic buildings, and the lint-choked dryer runs behind its hotels and care homes. It is the hardest-pressed kitchens - the University of Surrey, the Royal Surrey County Hospital, Surrey Sports Park and the town hotels - that glaze their hidden ducting quickest, and that coating is the road a fire takes.
The standard
TR19 Grease is the benchmark Guildford 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 Tunsgate Quarter and Guildford Wharf, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Guildford 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 Guildford hotels, care homes and gyms.
On the ground in Guildford
We are in Guildford's ductwork and plant every week. The proof is the jobs, not the stock photos.
A launderette in Guildford had flammable textile lint filling more than half the horizontal tumble-dryer exhaust runs. We ran high-powered vacuum extraction and non-sparking flexible rods to sweep the long lines clear to the outside, doubling the outlet velocity and removing the fire hazard. We advised the owner on fitting a secondary inline lint-collection box to simplify the weekly maintenance.
When it is due
Ductwork rarely warns you politely. In a busy Guildford kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Tunsgate Quarter cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Guildford insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying North 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 Guildford 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 Guildford Wharf 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 Guildford fire logbook.
Why it matters
Three duties push every Guildford 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 Guildford 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 Tunsgate Quarter 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 current TR19 Grease certificate is the evidence your Guildford insurer expects. Without it, a fire claim can be reduced or refused outright - an expensive gap to find after the event.
Hygiene and environmental health. Guildford Borough Council food hygiene inspections assess the physical condition of premises, ventilation included. A grease-clogged system can count against the rating an Environmental Health Officer awards, quite apart from the smell and the falling extract performance your staff have to work in.
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 Tunsgate Quarter kitchen sits in a tighter band than a daytime North Street cafe. We measure the grease load and confirm your interval.
Yes. We work overnight, early mornings and closing days for the Tunsgate Quarter and North Street 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 Guildford offices, schools and public buildings, and the lint-heavy laundry ducts in the Surrey hotels and care homes, alongside kitchen grease ducts.
Little, if it is planned. We survey the Guildford run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a North Street cookline is back in service for the next shift.
Yes. The fan at the top of a Guildford Wharf 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 Tunsgate Quarter and North Street kitchens to the offices, schools and industrial units across Guildford and the wider Surrey.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Tunsgate Quarter operator's insurer and fire risk assessor expect.
