TR19 inspection for kitchens and businesses in Orpington
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 Orpington and the rest of Greater London. Common call-outs are for systems that need surveying before cleaning and kitchens whose menu or hours have changed, on post-clean checks, deposit thickness tests and wet film thickness tests.
Kitchens in Orpington, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
Results last longer with the right care. We suggest:
- Book the next test on the date in the report
- Send TR19 audit reports to your insurer on request
- Never cook with filters missing
- Keep canopy edges and gutters wiped down
After post-clean verification, file the results with the cleaning certificate. The pair gives a clear record of the clean and the check.
Close the access gaps found during inspection, so grease isn’t left building in hidden parts.
How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a morning or less for one kitchen, more where there are several systems. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Orpington.
- First we book a time that won’t disrupt cooking.
- The system is checked from canopy to discharge.
- Grease readings are taken at set points using WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- The findings go into a report with readings, pictures and a recommended next clean.
Preparing for the visit
- Have your last certificate or report to hand
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know when the site is closed or quiet
How to get a quote
To help us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or send us an email.
Advice
When something else is needed
We will always give you a straight diagnosis, so here’s what TR19 inspection won’t do:
- Parts of the duct nobody can reach yet
- The legal duty, which stays with the responsible person
- Ductwork that was designed or installed badly
If in doubt, call us on 0345 646 2711 or email us and we will say what we think before you book.
What the work covers
- Post-clean checks
- Insurer audits
- Access surveys
- Pre-clean surveys
- Wet film thickness tests
- Deposit thickness tests
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Why act early in Orpington
After an incident, an insurer can ask to see proof of TR19 cleaning and inspection. Missing records can put a claim at risk. An up-to-date inspection report is a good place to start. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

What TR19 inspection looks like in Orpington
The Food Standards Agency lists about 12 bars, pubs and nightclubs as registered food businesses within roughly a mile and a half of the centre of Orpington. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Environmental health officers from Bromley council inspect food businesses in Orpington. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready. London jobs usually start after the last service, with loading and roof access agreed with the building first.
A hall kitchen that only cooks for events, whether near St Andrew's or elsewhere in Orpington, still needs its extract cleaned, just less often. Term dates shape school work: for a school like Perry Hall Primary School, an extract clean fits neatly into a half-term or summer break. If you run a café or takeaway near St Mary Cray station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

What the work involves, part by part
Horizontal duct runs
Grease settles on the floor of horizontal ducts as the air cools. We test at points along the run through access panels.
Extract fan and discharge
We look at where the extract discharges outside, as grease can build up there too.
Questions from Orpington
Do you work overnight in Orpington?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
Which environmental health team covers Orpington?
Kitchens in Orpington are inspected by Bromley 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.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.
What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
What happens on a pre-clean survey?
A survey finds out how the system is laid out, how dirty it is and what can be reached, before anyone starts cleaning. Any access problems are flagged ahead of the clean.
What does TR19 inspection cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Multi-site and managed buildings
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
