Dorchester · TR19 Grease
We degrease the canopy, baffle filters and extractor fan for Dorchester restaurants, takeaways and pubs - so the system pulls properly, runs cooler and holds a current TR19 certificate.
Dorchester
Dorchester fries hard along High East Street, Cornhill and Trinity Street, where takeaways, cafes and restaurants run their extraction flat out through every service.
The settings vary, the grease does not. Across High East Street, Cornhill and the suburban strips, the takeaways and grill houses run the single hardest test an extraction canopy faces. Dorchester rates hundreds of food premises, most of them frying in a tight footprint.
What the High East Street and Cornhill cooks labour under - canopy, baffle filters and extractor fan - is exactly what we degrease. Cleaned right it draws as it was meant to, clearing heat and steam, carrying a current TR19 Grease certificate and running cooler, since a clean Dorchester fan no longer battles a greased one to shift the same air.
The system
Extraction cleaning is the accessible heart of the system - the kit above a hard-frying High East Street cookline that does the work and shows the grease first.
We strip and degrease the canopy inside and out, clean or replace the baffle filters, and degrease the extractor fan and its housing - the part that quietly loses performance as grease loads the blades over a hard Cornhill service. Cleaned to the TR19 Grease standard, with before-and-after evidence and a certificate, so the system pulls properly and your Dorchester fire risk assessment and insurer have the record they ask for.
Filters
The standard for commercial cooklines: they trap grease and slow flame spread. Cleaned, or replaced when warped or corroded.
Common on older or lighter setups; they clog fast and pass grease through if neglected. We flag where a baffle upgrade is overdue.
On the odour and emission-controlled systems near Dorchester's residential streets; cleaned or changed so the downstream stages are not overwhelmed.
Fire
A Dorchester cookline's extraction and its fire protection are one system - and a clean is the moment to check the join.
Nozzles aimed at the canopy and cooking points; grease build-up around them on a busy High East Street line is exactly what they exist to fight. We clean around them without disturbing the system.
Where the gas shuts off if extraction fails on a High East Street line, we work without tripping it - and flag it if it is not behaving.
Checked for the grease that would stop them closing - a quiet failure point on a Cornhill system that a quick canopy wipe misses.
On the ground in Dorchester
We are under Dorchester's canopies every week. Real jobs, not stock shots.
A town-centre Dorchester bar and grill was carrying a heavy grease load on the canopy and the first bend of the duct, straight off the cook line. We stripped and soaked the filters, scraped the filters and duct back and degreased the accessible run to the fan. Everything came up clean and safe with a much stronger draw across the canopy, and we left the paperwork for the records. Access was tight, so we loaded in through the back to reach the far end.
Why it pays
Extraction cleaning is a fire-risk job first - but it pays back every Dorchester service.
A clean canopy and fan clear the heat and steam off a hard High East Street cookline faster, so the kitchen runs cooler and the fan draws less to move the same air. A greased system is a fire risk, a failed inspection point and a comfort problem at once. Frequency tracks how hard you cook - the Cornhill takeaways need it more often than a daytime cafe - and your certificate sets the interval.
Inspect the Dorchester canopy, filters and fan, agree scope and frequency.
Remove filters and access panels, protect the cookline.

Questions
It depends how hard the kitchen runs. Under TR19 Grease, heavy use of 12 to 16 hours a day points to roughly every three months, moderate to every six, light to every twelve. A busy High East Street or Cornhill kitchen sits in a tighter band than a daytime cafe.
Yes. Where a filter is warped, corroded or a mesh type that keeps passing grease, we say so and swap it - common on the older Cornhill takeaway canopies that have run hot for years.
Yes - from High East Street, Cornhill and the city centre out to the suburbs, and across the wider Dorset.
Yes. Most venues we clean around High East Street and Cornhill are busy through the evening, so we work overnight, early mornings or on closing days, at no extra charge for out-of-hours work.
It can. An inspection covers the physical condition of the premises, ventilation included, so a grease-laden canopy or fan over a High West Street cookline can count against your score.
Yes. Beyond restaurants, Dorchester has the hospital, hotel and town-centre kitchens we clean and certify - high-volume systems we clean and certify alongside the hospitality work.
Yes. The takeaways and grill houses around Cornhill and Trinity Street run a canopy, filters and a fan and often carry a heavy grease load for their size. We clean and certify them the same way as a full restaurant system.
Local knowledge
In 1685 Judge Jeffreys held his Bloody Assizes in the Oak Room of the Antelope Hotel on Cornhill, and in 1834 the Tolpuddle Martyrs were tried a few doors away in the Shire Hall, now a museum of that struggle. The town turns on food and hospitality today, and its busy kitchens coat their canopies and extract systems in grease every service. Left in place it feeds flame and starves airflow, so we strip, degrease and certify extraction from the filter to the fan to the TR19 grease standard.
