Merthyr Tydfil · 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 Merthyr Tydfil, and certify it to the TR19 Grease standard your insurer expects.
Merthyr Tydfil
Merthyr Tydfil 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 Pontmorlais to Glebeland Street and Castle Street, 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.
The same crews clean dry ventilation and air-handling ductwork in offices, schools and civic buildings, plus the combustible lint runs behind hotel and care-home dryers. High-turnover sites - The College Merthyr Tydfil, the Prince Charles Hospital, the St Tydfil Shopping Centre and the town hotels - build grease fastest in the concealed lengths where flame spreads.
The standard
TR19 Grease is the benchmark Merthyr Tydfil 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 Pontmorlais and Castle Street, 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 Merthyr Tydfil 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 Merthyr Tydfil hotels, care homes and gyms.
On the ground in Merthyr Tydfil
We are in Merthyr Tydfil's ductwork and plant every week. The proof is the jobs, not the stock photos.
A High Street restaurant in Merthyr Tydfil had a heavy grease film through the horizontal extract and up the riser above a busy cook line. We fitted new access panels, hand-scraped the accessible lengths and ran an enzyme degreaser through the sealed sections, returning the ductwork to clean metal for the fire and insurance standard. It was worked overnight so the town-centre trade lost no covers, and we flagged the neighbouring unit up toward the old Cyfarthfa ironworks quarter whose cook line tied into the same sealed riser and roof outlet. Merthyr, where Trevithick ran the world's first steam locomotive along the Penydarren tramroad in 1804, still knows iron and heat, and we left a marked-up riser plan and grease-depth readings for the file. The riser climbed three floors behind a boxed-in shaft, so we opened it at each landing, rodded the tight bends and swabbed the flat sections by hand before the final wash-down, then checked the pull at the roof cowl to confirm it drew cleanly again.
When it is due
Ductwork rarely warns you politely. In a busy Merthyr Tydfil kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Pontmorlais cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Merthyr Tydfil insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Glebeland 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 Merthyr Tydfil 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 Castle Street 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 Merthyr Tydfil fire logbook.
Why it matters
Three duties push every Merthyr Tydfil 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 Merthyr Tydfil 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 Pontmorlais 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. To a Merthyr Tydfil insurer a current TR19 Grease certificate is the proof the extract has been kept up. Let it lapse and a fire claim can be scaled back or declined outright - the kind of gap nobody wants to find with the kitchen already gutted.
Hygiene and environmental health. Merthyr Tydfil 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 Pontmorlais kitchen sits in a tighter band than a daytime Glebeland Street cafe. We measure the grease load and confirm your interval.
Yes. We clean the dry ductwork and air-handling in Merthyr Tydfil offices, schools and public buildings, and the lint-heavy laundry ducts in the South Wales hotels and care homes, alongside kitchen grease ducts.
Yes. We work overnight, early mornings and closing days for the Pontmorlais and Glebeland Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
Yes - from Pontmorlais and Glebeland Street kitchens to the offices, schools and industrial units across Merthyr Tydfil and the wider South Wales.
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 Pontmorlais and Castle Street where the runs are long and awkward.
A dated TR19 certificate, before-and-after photographs of each section, and an access report for your fire logbook - the evidence a Pontmorlais operator's insurer and fire risk assessor expect.
Little, if it is planned. We survey the Merthyr Tydfil run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Glebeland Street cookline is back in service for the next shift.
