How we handle TR19 inspection in Berrylands
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). The results show whether the system needs cleaning and how soon. If you are dealing with kitchens whose menu or hours have changed and kitchens taken over with no cleaning records, we can help.
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. For a kitchen in Berrylands, that typically means a longer system to clean and more access panels to plan around.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Why it’s worth doing now in Berrylands
A pre-clean survey avoids surprises on the night. Access problems are spotted in advance rather than on the night, and the quote reflects the real job. Choosing the date yourself beats having a fault choose it for you.
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 make a difference.

How we price TR19 inspection
The survey tells us what the work involves. We look at:
- When the work can happen, such as evenings, overnight or weekends
- Whether several sites go on one quote
- Whether it’s a one-off visit or part of a schedule
- The condition we find in the survey
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
Helping us quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Your last certificate, test record or report
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business
- The times we could work without disrupting the site
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Different parts, different methods
Horizontal duct runs
If a run has no access panel, we note it so panels can be added.
Extract fan and discharge
We look at where the extract discharges outside, since grease reaches the very end of the system.
How it works
Every visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, clear away and leave you the report. On site, the work takes an hour or two for a single kitchen, longer for a large or complex system. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Berrylands.
- 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.
- Photos are taken to show the condition after the clean.
- We report the findings and flag any areas that need more work.
How to prepare
- 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
- Tell us where we can park and unload
Getting a quote
To get a fixed quote, give us a ring on 0345 646 2711 or use the quote form 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 normally come back within one working day.
Related advice
Between visits
Results last longer with the right care. We suggest:
- Look out for grease drips round the canopy edge
- Store grease readings where your insurer can see them
- Diary the next grease test and clean
- Flag changes in how much frying the kitchen does
The report recommends when the system should next be cleaned and tested, based on the readings and how the kitchen is used.
Close the access gaps found during inspection, so grease isn’t left building in hidden parts.
When it’s something else
It’s worth knowing the limits before booking:
- The legal duty, which stays with the responsible person
- A faulty or failing extract fan
- Heavy deposits found on test, which still need cleaning
If in doubt, ring 0345 646 2711, or send details by email and we will say what we think.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
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 they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
FAQs for Berrylands
Can school kitchens in Berrylands be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 45 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Berrylands. Send us your term dates when you call us on 0345 646 2711 or email us, and we’ll fit the work in.
Which fire service covers Berrylands?
Berrylands is in the area of London Fire Brigade. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
When should we have our next grease test?
It depends on how heavily the kitchen cooks. 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.
Do we have to follow TR19 by law?
No. TR19® is a specification, not a statute. Without TR19 records, an insurance claim can be reduced or refused, so it matters in practice.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What grease levels does TR19 allow?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
What do you need from me for a quote?
A short description and a few pictures plus the address and your hours. If we need more, we’ll ask.
