TR19 inspection for kitchens and businesses in Harrow on the Hill
Post-clean verification is a check carried out once the cleaning is done, with new readings and pictures of the cleaned areas. It shows whether the system was left in the condition the paperwork describes. Common call-outs are for missing access panels found on survey and checking the result of a recent clean, on pre-clean surveys, wet film thickness tests and access surveys.
Kitchens in Harrow on the Hill, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Aftercare tips
After the visit, a few habits help the work last:
- Store grease readings where your insurer can see them
- Have the latest report ready for insurance renewals
- Keep to the recommended interval
- Flag changes in how much frying the kitchen does
After the inspection, we send a report showing each reading, its location and pictures. File it alongside your TR19 certificates.
Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.
Common questions in Harrow on the Hill
Who carries out food hygiene inspections in Harrow on the Hill?
Food hygiene inspections in Harrow on the Hill are carried out by Brent council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
How do you handle parking and loading in Harrow on the Hill?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. If the building has a loading slot system, we will book into it.
What do you need from me for a quote?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply ring 0345 646 2711 or send us an email.
How often should a kitchen extract be inspected?
That varies with the kitchen’s daily use. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and testing shows if your kitchen needs more.
How far ahead should we book?
Earlier is better, particularly for night and weekend visits. We usually quote within one working day, and emergencies are covered by our 24/7 line.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What do the grease readings need to be?
TR19® Grease says grease should not go over a mean of 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
How do you measure grease in a kitchen extract?
WFTT and DTT are the two methods for measuring grease thickness, in microns. We take readings at set points from canopy to fan.
Do you need TR19 inspection in Harrow on the Hill?
Some parts of a system are hard to reach, and grease can be missed there clean after clean. A survey finds the sections that can’t be reached, so panels can be fitted.
If you notice any of these, it’s worth a diagnosis:
- Heavy grease suspected in the plenum or ducts
- Confirming a clean reached the whole system
- Parts of the system left out of past cleans
- Systems cleaned on a calendar with no measurements
Church and community hall kitchens, near Christ Church or anywhere around Harrow on the Hill, are easy to forget, but their extracts collect grease like any other.
What your quote should include
- Whether they recommend a next date
- What happens if part of the system can’t be accessed
- Whether a written report and photos are included
- When they can work, and whether that’s outside your opening hours
When something else is needed
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- Fire safety duties beyond the extract system
- Removing the grease, which is a separate clean
- Fan breakdowns, which need a repair visit
If you’re not sure, just phone us on 0345 646 2711 or drop us a line and we’ll give you a straight answer before you book.
What the work covers
- Pre-clean surveys
- Deposit thickness tests
- Insurer audits
- Access surveys
- Wet film thickness tests
- Post-clean checks
Why deal with it now?
Surveying first means the clean goes to plan. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, and the quote reflects the real job. For a site in Harrow on the Hill, fitting the work in overnight now is far easier than closing at short notice later.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

All told, the work takes around an hour or two per canopy and duct system. Before any visit in Harrow on the Hill, we agree where the van can stop and how equipment reaches the system.
- The visit is arranged for when the kitchen isn’t busy.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- You get a report with readings, photos and recommendations.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Mention any sign-in, permit or induction we need
- Arrange a key holder or contact on site
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Advice
What affects the cost of TR19 inspection
The survey tells us what the work involves. We look at:
- The condition of the system
- Where the site is and how we reach it
- How big the system is
- Working hours and out-of-hours timing
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.
What we need to know
When you contact us, these details help:
- Close-ups of filters, grilles, hatches or access panels
- Wide pictures of the system and the area around it
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.

Bends and long runs can hold heavy deposits, well away from where anyone looks.
Canopy and plenum
Clean-looking filters do not mean a clean plenum. That is why we test behind them.
