TR19 inspection for kitchens and businesses in Kingswood
Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. A TR19 audit sets out the system’s condition, with readings and pictures, for sites in Kingswood and the rest of Buckinghamshire. The work covers wet film thickness tests, access surveys and deposit thickness tests, and people most often call us about confirming a clean reached the whole system and heavy grease suspected in the plenum or ducts.
In a small place like Kingswood, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

How it works
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes anything from an hour for a small canopy and short duct to a good part of a day for a large site, and the area is cleaned down before we leave. Visits to a village like Kingswood are booked in advance, at a time that suits whoever runs the site.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- We take WFTT or DTT readings at set points along the system.
- We photograph the test points and record any sections we can’t reach.
- The findings go into a report with readings, pictures and a recommended next clean.
How to prepare
- Find the previous report, if there is one
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. 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. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.

FAQs for Kingswood
Do you work overnight in Kingswood?
Yes, out-of-hours work is a big part of what we do. That way a site in Kingswood doesn’t have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Can you get to a site in Kingswood?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
How do you protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
How much does TR19 inspection cost?
It depends on the site, so we quote each one individually. For a quote, ring 0345 646 2711 or drop us a line and tell us about the site and its opening hours.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Is TR19 cleaning the law?
No. TR19® is not law; it’s BESA’s specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, which requires the responsible person to reduce fire risk, and insurers, fire officers and EHOs look to TR19® as the benchmark.
When something else is needed
To be straight with you, some problems need a different fix:
- The legal duty, which stays with the responsible person
- Heavy deposits found on test, which still need cleaning
- A faulty or failing extract fan
If you are not sure, just phone us on 0345 646 2711, or email photos and we will give you a straight answer.
Parts of the system we cover
- Insurer audits
- Wet film thickness tests
- Pre-clean surveys
- Deposit thickness tests
- Post-clean checks
- Access surveys
Looking after it afterwards
To keep the system working properly between visits:
- Wipe the canopy surfaces regularly
- Never cook with filters missing
- Keep TR19 certificates, readings and reports together
- Share inspection reports with your insurer or broker when asked
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can arrange it.
Close the access gaps found during inspection, so grease is not left building in hidden parts.
What affects the cost of TR19 inspection
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
- Any permits to work or inductions
- The condition of the system
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
Helping us quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Close-ups of filters, grilles, hatches or access panels
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
- Your opening hours and when the area is out of use

Why act early in Kingswood
Skipping grease testing leaves the cleaning interval to guesswork. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, which you won’t know without measuring. Planning a trip to Kingswood ahead is easier for everyone than a rushed one.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before any work starts.

When to call us in Kingswood
Grease builds up as cooking vapour cools inside the extract. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.
Keep an eye out for any of the following:
- Checking the result of a recent clean
