Honest limits
In fairness, there are a few things this work won’t fix:
- Fire safety duties beyond the extract system
- Ductwork that was designed or installed badly
- Heavy deposits found on test, which still need cleaning

TR19 inspection in Whetstone, done properly
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Testing is how you know where your system stands. We’re often asked to deal with extracts that have never been grease tested and kitchens taken over with no cleaning records, across deposit thickness tests, post-clean checks and pre-clean surveys.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Whetstone, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

TR19 inspection around Whetstone
The FSA’s food hygiene register shows about 139 restaurants, cafés and canteens and about 52 sandwich bars and takeaways across Whetstone and its immediate surroundings (about a mile and a half). Each kitchen extract among them can be measured for grease to set the right cleaning interval. Environmental health officers from Barnet council inspect food businesses in Whetstone. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. London Fire Brigade covers Whetstone. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
Commuter trade near Oakleigh Park station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. A hall kitchen that only cooks for events, whether near Church of St John or elsewhere in Whetstone, still needs its extract cleaned, just less often. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Finchley Memorial Hospital is the nearest hospital to Whetstone, about 1.4 miles south.

Different parts, different methods
Canopy and plenum
Filters can look fine while the plenum behind them is heavily coated. That’s why we test behind them.
Schools, hospitals and care homes
Education kitchens need TR19 inspections like any other. Readings show if the interval is right.
How the visit works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes around an hour or two per canopy and duct system. Security desks and permits-to-work are routine in London, so let us know what your building in Whetstone needs from us.
- We go through any past certificates and reports.
- The layout is traced from the canopy to the discharge.
- Access panels are located and any missing ones noted.
- Grease readings are taken and pictures recorded.
- We report back with readings and a fixed quote.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool
- Let us know how we reach the system, including roofs, risers and plant rooms

What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Between visits
Results last longer with the right care. Here’s what we suggest:
- Share inspection reports with your insurer or broker when asked
- Clean grease off the canopy between professional cleans
- Diary the next grease test and clean
- Keep access panels clear and unpainted
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can quote to do it.
Keep all TR19 records together so the history is easy to show.
What affects the quote in Whetstone
You’ll get a fixed price before any work starts. It’s based on:
- Whether we need access equipment or extra panels
- Site requirements such as sign-in and permits
- The times the site is available
- The scale of the work
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.
Helping us quote
You do not need the technical terms. It helps if you can send:
- A few general shots of the system
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
- Any access panels or hatches you can see
Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
Is there a survey before the work?

Do you cover Whetstone?
Yes. Our area takes in London and the counties of South East England, and that includes Whetstone.
How often should grease be tested?
We suggest a next test date in every report, taking the readings and the kitchen’s hours into account. The interval should come from a competent person’s risk assessment backed by grease measurement.
