Harrow · TR19 Grease
We degrease the canopy, baffle filters and extractor fan for Harrow restaurants, takeaways and pubs - so the system pulls properly, runs cooler and holds a current TR19 certificate.
Harrow
Harrow fries across the borough - the Station Road and Rayners Lane cooklines cook from open to close, and the St Ann's Road and Wealdstone kitchens run alongside.
Different kitchens, same grease. Around Rayners Lane, Kenton Road and the outlying strips, the grill houses and takeaways put an extraction canopy through the hardest work it will ever do. With around 1,700 food premises rated across Harrow, most are frying in a cramped space.
We degrease the part of the system the Rayners Lane and Kenton Road cooks work under - the canopy, the baffle filters and the extractor fan. Done properly it pulls the way it was designed to, clearing heat and steam, holding a current TR19 Grease certificate, and running cooler, because a clean Harrow fan is not fighting a greased one to move the same air.
The system
Extraction cleaning is the accessible heart of the system - the kit above a hard-frying Rayners Lane 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 Kenton Road service. Cleaned to the TR19 Grease standard, with before-and-after evidence and a certificate, so the system pulls properly and your Harrow 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 Harrow's residential streets; cleaned or changed so the downstream stages are not overwhelmed.
Fire
A Harrow 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 Rayners Lane 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 Rayners Lane 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 Kenton Road system that a quick canopy wipe misses.
On the ground in Harrow
We are under Harrow's canopies every week. Real jobs, not stock shots.
A restaurant in Harrow had carbonised grease throughout the ventilation system from a long stretch without maintenance. We ran a full system deep-clean, hand-cleaning the access points and working rotary brushes through every duct section, restoring the extraction to the TR19 standard. During the clean we found signs of an earlier pest problem and flagged it for the operator.
Why it pays
Extraction cleaning is a fire-risk job first - but it pays back every Harrow service.
Clear the canopy and fan of grease and a hard Rayners Lane cookline sheds its heat and steam faster, so the kitchen keeps cooler and the fan works less to move the same air. Leave it caked and you carry a fire risk, a failed inspection point and an uncomfortable kitchen at once. How often it is due tracks the cooking - the Kenton Road takeaways well beyond a daytime cafe - and your certificate names the next date.
Inspect the Harrow 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 Rayners Lane or Kenton Road kitchen sits in a tighter band than a daytime cafe.
Extraction cleaning covers the canopy, filters and fan; where the concealed duct run behind them is also loaded - as it often is in a tight Rayners Lane kitchen - we clean the full run to TR19 and certify it together.
Yes. Most venues we clean around Rayners Lane and Kenton Road are busy through the evening, so we work overnight, early mornings or on closing days, at no extra charge for out-of-hours work.
Yes. The takeaways and grill houses around Kenton Road and St Anns Road 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.
Yes. Beyond restaurants, Harrow has campus catering at the University of Westminster Harrow campus, production kitchens at Northwick Park Hospital, and shopping-centre and hotel kitchens - high-volume systems we clean and certify alongside the hospitality work.
Yes - from Rayners Lane, Kenton Road and the city centre out to the suburbs, and across the wider Greater London.
It can. An inspection covers the physical condition of the premises, ventilation included, so a grease-laden canopy or fan over a Station Road cookline can count against your score.
