Brecon · 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 Brecon, and certify it to the TR19 Grease standard your insurer expects.
Brecon
Brecon rates dozens 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 Brecon, from High Street through Ship Street to Watton, 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 - barracks mess halls, pub carveries and festival catering - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Brecon 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 High Street and Watton, 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 Brecon 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 Brecon hotels, care homes and gyms.
On the ground in Brecon
We are in Brecon's ductwork and plant every week. The proof is the jobs, not the stock photos.
A high-street library in Brecon had a heavy blanket of dust settled through the branch supply ducts serving the reading rooms. We power-brushed the branch supply ducts under HEPA negative pressure and cleared the ceiling diffusers. Supply air was restored to a clean standard and the ductwork was left clean throughout.
When it is due
Ductwork rarely warns you politely. In a busy Brecon kitchen these are the tells.
The tells are plain: steam that lingers, odours drifting back over the diners, drips off the canopy onto a High Street line, a rim of grease at the filters, or a Brecon insurer or fire assessment wanting a TR19 certificate you cannot show. Frequency tracks the cooking load - a hard-frying Ship Street kitchen needs it far more often than a quiet cafe - and your certificate sets the date, so nothing is left to chance.
How it runs
Inspect the full Brecon 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 Watton 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 Brecon fire logbook.
Why it matters
Three duties push every Brecon 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 Brecon 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 High 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. A live TR19 Grease certificate is what a Brecon 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. When Powys County Council carries out a food hygiene inspection it judges the physical state of the premises, and ventilation is part of that. A grease-choked extract can pull down the rating an Environmental Health Officer gives, on top of the odour and the weakening airflow your staff put up with.
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 High Street kitchen sits in a tighter band than a daytime Ship Street cafe. We measure the grease load and confirm your interval.
Little, if it is planned. We survey the Brecon run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Ship Street cookline is back in service for the next shift.
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 High Street and Watton where the runs are long and awkward.
Yes. We work overnight, early mornings and closing days for the High Street and Ship Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
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 Watton 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 High Street operator's insurer and fire risk assessor expect.
Yes. The fan at the top of a Watton 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.
Local knowledge
The Monmouthshire and Brecon Canal reached its Brecon terminus in 1800, carrying limestone, coal and farm produce down towards Newport until the railways took the trade. Today the canal basin draws walkers and boaters rather than cargo. The kitchens and workshops that serve them run ductwork that, like a canal, silts up unseen: grease and dust build in the runs until airflow fails, which is why extraction ducting is stripped, cleaned and certified along its full length.
