TR19 inspection in North Marston
A grease test measures how thick the grease is inside a kitchen extract system. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). From the numbers, you can see whether cleaning is due. The work covers deposit thickness tests, post-clean checks and access surveys, and the jobs we see most are cleaning intervals that may not suit the kitchen and insurers asking for TR19 evidence.
In a small place like North Marston, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Duct Doctor has been trading since 2009, as 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.

What the work involves, part by part
Restaurants, pubs and hotels
A kitchen running from breakfast to late service builds grease quickly. Readings show if the cleans are frequent enough.
Canopy and plenum
Filters can look fine while the plenum behind them is heavily coated. So we measure behind the filters, not just in front.

What we work on in North Marston
- Pre-clean surveys
- Insurer audits
- Access surveys
- Wet film thickness tests
- Deposit thickness tests
- Post-clean checks
Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Flag oily drips near the extract
- Clean grease off the canopy between professional cleans
- Clean or swap grease filters as often as the kitchen needs
- Keep the route to access panels clear
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can quote to do it.
Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.

- Sites with gaps in their extract records
- Systems cleaned on a calendar with no measurements
- Systems that need surveying before cleaning

- Which accreditations they hold, and whether you can check them
- How they set the interval to the next visit
- Whether the price is fixed
How the visit works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes an hour or two for a single kitchen, longer for a large or complex system. Visits to a village like North Marston are booked in advance, at a time that suits whoever runs the site.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Before we arrive
- Tell us about site rules, permits or sign-in
- Find the previous report, if there is one
- Allow time for equipment near the work to be turned off and cool down
Get a fixed quote
To get a fixed quote, phone us on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We usually come back within one working day.

North Marston: your questions answered
Who would carry out a food hygiene inspection at a kitchen in North Marston?
Kitchens in North Marston are inspected by Buckinghamshire council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Will you come out to North Marston?
Yes. North Marston is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Can you look after several sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What grease levels does TR19 allow?
The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. We show your readings against those figures.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What is post-clean verification?
After a clean, we take new readings and photos to show how the system was left. It can follow our own cleans or another contractor’s.
