Caerphilly · 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 Caerphilly, and certify it to the TR19 Grease standard your insurer expects.
Caerphilly
Caerphilly 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.
Right across Caerphilly, from Cardiff Road through Castle Street to Trecenydd, cooklines share tight roof space and vent through concealed ducting few operators ever see inside. We clean that entire path to the TR19 Grease standard, canopy through to fan, taking in the level pulls and the risers where grease settles thickest and a fire would run.
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 - hospital kitchens, college refectories, pub and cafe 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 Caerphilly 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 Cardiff Road and Trecenydd, 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 Caerphilly 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 Caerphilly hotels, care homes and gyms.
On the ground in Caerphilly
We are in Caerphilly's ductwork and plant every week. The proof is the jobs, not the stock photos.
A guest house in Caerphilly had a thick mat of fabric fluff packed into its tumble-dryer exhaust run, a clear fire risk. We stripped and vacuumed the full vent line, cleared the discharge louvre and checked the airflow. The system ran cooler and cleaner with the dryers clearing their loads more freely, and the difference showed straight away; we worked the early mornings before staff arrived to keep the place running.
When it is due
Ductwork rarely warns you politely. In a busy Caerphilly 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 Cardiff Road line, grease crusting at the filter rims, or a Caerphilly 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 Castle Street 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 Caerphilly 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 Trecenydd 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 Caerphilly fire logbook.
Why it matters
Three duties push every Caerphilly 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 Caerphilly 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 Cardiff 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 current TR19 Grease certificate is the evidence your Caerphilly 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. Caerphilly County 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 Cardiff Road kitchen sits in a tighter band than a daytime Castle Street cafe. We measure the grease load and confirm your interval.
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 Cardiff Road and Trecenydd where the runs are long and awkward.
Yes. We clean the dry ductwork and air-handling in Caerphilly offices, schools and public buildings, and the lint-heavy laundry ducts in the Caerphilly hotels and care homes, alongside kitchen grease ducts.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Cardiff Road operator's insurer and fire risk assessor expect.
Yes. The fan at the top of a Trecenydd 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.
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 Trecenydd conversions where the run was boxed in with no hatches.
Yes. We work overnight, early mornings and closing days for the Cardiff Road and Castle Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Local knowledge
The steam coal of the Rhymney Valley made Caerphilly's fortune and, on 14 October 1913, its greatest tragedy, when an explosion at the Universal Colliery in Senghenydd just up the Aber Valley killed 439 men and a rescuer - the worst mining disaster in British history, driven on by firedamp gas and airborne coal dust in workings whose ventilation had failed to keep pace with the law. Air kept those pits alive, and when it faltered fire found its path. Modern premises hide their dust inside sealed ductwork instead, where grease and debris build unseen until airflow drops or fire finds a way through. We clean and inspect ventilation and extract ductwork across the town, then hand over photographic before-and-after evidence of every run.
