TR19 inspection for kitchens and businesses in Greenhill
Not every kitchen fits neatly into a calendar. In a busy kitchen, grease can build faster than the minimum intervals allow for, which is why measurement matters. Our readings give your risk assessment real numbers to work from. The work covers wet film thickness tests, insurer audits and pre-clean surveys, and common reasons people get in touch are confirming a clean reached the whole system and missing access panels found on survey.
Kitchens in Greenhill, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Why it’s worth doing now in Greenhill
A check after cleaning shows whether the work reached every part it should have, before the next clean is due. Leaving it on a busy London site only adds to the work.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

Greenhill: your questions answered
Which fire service covers Greenhill?
That’s London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can the work in Greenhill be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Greenhill keeps running as normal. Just ring 0345 646 2711, or send details by email with your opening times and we will plan around them.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
How do you measure grease in a kitchen extract?
The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. Readings are taken at set points through the system.
Will you produce a report for our insurer?
Yes. Insurers often want evidence the extract is managed to TR19®, and an audit report gives you that, along with any actions needed.
Do you work in Greenhill?
Yes. Our technicians work in Greenhill, within the South East and London area we cover.
Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Landlords, agents and facilities managers
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
How it works
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Expect the work in Greenhill to happen after your last customer leaves, not during trading.
- First we book a time that won’t disrupt cooking.
- The system is checked from canopy to discharge.
- Grease readings are taken at set points using WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- We send a report setting out the readings, photos and next steps.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Let us know when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool

Part by part
Restaurants, pubs and hotels
BESA’s minimum for heavy use of 12 to 16 hours a day is a clean every 3 months, with testing showing whether more is needed.
Extract fan and discharge
A greasy fan works harder and wears faster. The inspection shows whether it needs cleaning now.
TR19 inspection in Greenhill: the local picture
According to Food Standards Agency records, there are about 23 bars, pubs and nightclubs and about 3 hotels and B&Bs across Greenhill and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. London jobs usually start after the last service, with loading and roof access agreed with the building first. Food hygiene inspections in Greenhill are the job of Harrow council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Volunteers running a hall kitchen near Church of St John the Baptist, or anywhere in Greenhill, may not know when the extract was last cleaned, and a grease test settles it. A hospital like Northwick Park Hospital, about 0.7 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

What we are called out for in Greenhill
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. The old cleaning schedule may not match the kitchen any more.
Common reasons sites call us are:
- Insurance renewals needing proof of TR19 cleaning
- Confirming a clean reached the whole system
- Pre-clean surveys before a first TR19 clean
- Systems cleaned on a calendar with no measurements
Commuter trade near Harrow-on-the-Hill station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
