TR19 inspection in Cotman's Ash, done properly
A pre-clean survey is the diagnosis, and the clean is the treatment. Readings, pictures and notes on access are gathered from end to end, so the clean can be planned properly. We’re often asked to deal with sections of duct that can’t be reached and insurance renewals needing proof of TR19 cleaning, on access surveys, pre-clean surveys and wet film thickness tests.
For a kitchen in or near Cotman's Ash, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Report grease dripping from the canopy
- Wipe the canopy surfaces regularly
- Clean or swap grease filters as often as the kitchen needs
- Mention new equipment or longer hours at the next test
After post-clean verification, file the results with the cleaning certificate. Together they show the system was cleaned and checked.
Test grease regularly instead of relying on the calendar. It spots changes in how fast grease builds.
What TR19 inspection cannot fix
It’s worth knowing the limits before booking:
- Installation problems, which fall under design guidance such as DW172
- A faulty or failing extract fan
- Removing the grease, which is a separate clean

Fixed quotes for TR19 inspection in Cotman's Ash
A fixed price needs a few facts first. We check:
- The number of sites or systems
- Whether it’s a one-off visit or part of a schedule
- The condition we find in the survey
- How easy every part is to reach
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before any work starts.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- The times we could work without disrupting the site
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
- Problems your staff have spotted
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or email photos.
Your questions about TR19 inspection in Cotman's Ash
Can you work in Cotman's Ash outside opening hours?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Just call 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
Which fire authority looks after Cotman's Ash?
Cotman's Ash is in the area of Kent Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
Can you price the work without visiting?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. Some sites still need a visit, and we will say so.
At what point does grease need cleaning?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, with 500 microns or more anywhere needing immediate spot cleaning.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. At the end, the area is cleaned down.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.

How the visit works

- First we book a time that won’t disrupt cooking.
- 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.
- We send a report setting out the readings, photos and next steps.
Getting ready for the visit
- Clear loose items from the work area
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids
