Walton-on-Thames · 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 Walton-on-Thames, and certify it to the TR19 Grease standard your insurer expects.
Walton-on-Thames
Walton-on-Thames 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 New Zealand Avenue to Hersham Road and Ashley Park, 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 - restaurant and hotel kitchens, pub kitchens, cafes 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 Walton-on-Thames insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
Grease is measured by thickness, and the standard sets the depth at which a system must be cleaned and re-tested. Around New Zealand Avenue and Ashley Park, where the concealed runs thread through mixed roof voids, a canopy-and-filter wipe leaves the ductwork itself - the long hidden sections where grease accumulates and a fire travels - untouched. We access the full Walton-on-Thames run through existing and newly fitted inspection hatches, clean to bare metal, record before-and-after grease-depth readings at set points, and issue a TR19 Grease certificate with a post-clean depth record.
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 Walton-on-Thames hotels, care homes and gyms.
On the ground in Walton-on-Thames
We are in Walton-on-Thames's ductwork and plant every week. The proof is the jobs, not the stock photos.
A small veterinary practice in Walton-on-Thames had supply grilles and main runs laden with dust and debris after years without a clean. I ran rotary brushes and a negative-air machine through the branch runs, then fitted fresh supply filters. Clean supply air was restored and everything was back to normal by opening. I worked steadily through so the patients on site barely registered me being there.
When it is due
Ductwork rarely warns you politely. In a busy Walton-on-Thames kitchen these are the tells.
A canopy dripping onto a New Zealand Avenue cookline, cooking smells forced back to the tables, extraction that no longer clears the steam, grease showing at the filter edges, or a Walton-on-Thames 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 Hersham Road 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 Walton-on-Thames 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 Ashley Park 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 Walton-on-Thames fire logbook.
Why it matters
Three duties push every Walton-on-Thames 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 Walton-on-Thames 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 New Zealand Avenue 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 Walton-on-Thames 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. A food hygiene visit from Elmbridge Borough Council weighs the physical state of the premises, ventilation counted within it. A grease-blocked extract can pull down the rating an Environmental Health Officer sets, quite apart from the stale smell and the tired airflow your staff work beneath all shift.
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 New Zealand Avenue kitchen sits in a tighter band than a daytime Hersham Road cafe. We measure the grease load and confirm your interval.
Yes. We clean the dry ductwork and air-handling in Walton-on-Thames 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 Walton-on-Thames run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Hersham Road cookline is back in service for the next shift.
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 Ashley Park conversions where the run was boxed in with no hatches.
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 New Zealand Avenue and Ashley Park where the runs are long and awkward.
Yes - from New Zealand Avenue and Hersham Road kitchens to the offices, schools and industrial units across Walton-on-Thames 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 New Zealand Avenue operator's insurer and fire risk assessor expect.
Local knowledge
Archibald Nettlefold bought the Hepworth studio in 1926 and ran it as Nettlefold Studios for decades, its sound stages and generating house wired with the ductwork and services that heavy production demands. Modern premises hide their air inside sealed ducting in much the same way, 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.
