TR19 inspection for kitchens and businesses in Langley
Taking on a kitchen in Langley with no cleaning records? Start with an inspection. You get readings, pictures and a clear view of what’s needed, so the next step is based on facts. The work covers wet film thickness tests, access surveys and post-clean checks, and people most often call us about extracts that may be over the 200 micron mean and uncertainty over how often to clean.
In a village or hamlet like Langley, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
A written report with photos follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

How it works
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the TR19 inspection, tidy up and leave you the report. On site, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. In a small place like Langley, the journey is planned ahead and the visit arranged around the site’s hours.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- Grease readings are taken at set points using WFTT or DTT.
- Each test point and any access problems are photographed.
- The findings go into a report with readings, pictures and a recommended next clean.
Getting ready for the visit
- Arrange a key holder or contact on site
- Clear the space around the work
- Plan for cooking equipment or plant to be off before we arrive

Getting a quote does not take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Related advice
Langley: your questions answered
Which environmental health team covers Langley?
Kitchens in Langley are inspected by Maidstone council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Is Langley within the area you cover?
Yes. Langley is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Do you carry out TR19 audits for insurers?
Yes. Our TR19 audits cover readings, photos, access and a recommended cleaning interval. It’s set out for your insurer or broker.
How long does grease testing take?
It takes around an hour or two per canopy and duct system. The visit is timed so cooking is not disrupted.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
What happens on a pre-clean survey?
We survey, measure and photograph the system first. The survey can be done from photos and details or on site, whichever suits the system.
Is a quote from pictures possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
What we are called out for in Langley
Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Knowing how much there is lets you act before it becomes a hazard.
It’s time to book a visit if you see:
- Kitchens whose menu or hours have changed
- An insurer’s request for a TR19 audit
- Sections of duct that can’t be reached
- Surveys needed before quoting a full clean
A hall kitchen that only cooks for events, whether near Church of St Mary or elsewhere in Langley, still needs its extract cleaned, just less often.
Before you book anyone
- Whether VAT is included
- What happens if part of the system cannot be accessed
- What hours they’ll be on site
- What records you’ll receive afterwards
What affects the quote in Langley
We don’t publish a price list, because sites vary so much. The quote depends on:
- Working hours and out-of-hours timing
- Travel, parking and unloading
- The size of the system
- Whether we need access equipment or extra panels
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any access panels or hatches you can see
Want a quote for TR19 inspection? Please call us on 0345 646 2711 or use the quote form with a few details about the site. We’ll explain what we’d do and send a fixed quote before anything is booked.
Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Clean or swap grease filters as often as the kitchen needs
- Keep TR19 certificates, readings and reports together
- Flag oily drips near the extract
- Keep the route to access panels clear
The audit report is set out to pass straight to your insurer or broker, with readings, photos and any areas not accessible.
Fit access panels where the survey finds sections can’t be reached, so every part of the duct can be cleaned.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection will not do:
- Parts of the duct nobody can reach yet
- The responsible person’s own fire risk assessment
- The grease itself, which needs a full or spot clean
If you are not sure, just give us a ring on 0345 646 2711 or drop us a line and we will give you a straight answer before you book.
What the work covers
- Insurer audits
- Access surveys
- Wet film thickness tests
- Deposit thickness tests
- Pre-clean surveys
- Post-clean checks
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too across Kent. Larger estates can be phased building by building to keep disruption down.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Why it’s worth doing now in Langley
Skipping grease testing leaves the cleaning interval to guesswork. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, which you will not know without measuring. Somewhere as small as Langley, losing a kitchen or building to a fault is felt by everyone who uses it.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
