TR19 inspection in Stockbury
Think of a TR19 inspection as the diagnosis before the treatment. We look at the system, take grease readings and photograph what we find, so the clean can be planned properly. The work covers deposit thickness tests, pre-clean surveys and post-clean checks, and the jobs we see most are kitchens taken over with no cleaning records and systems that need surveying before cleaning.
In a village or hamlet like Stockbury, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Your questions about TR19 inspection in Stockbury
Which fire authority looks after Stockbury?
That is Kent Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you cover smaller places like Stockbury?
Yes. Stockbury is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
What’s TR19?
A BESA 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.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
What is a WFTT or DTT grease test?
It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. Each reading is recorded in microns.
Is TR19 a legal requirement?
No. It’s the benchmark rather than the law. Without TR19 records, an insurance claim can be reduced or refused, so following it is the sensible course.
Why survey before a clean?
The survey covers the whole system, grease readings and access to each section. From it, we plan the clean and quote a fixed price.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
Part by part
Vertical risers
Risers can be hard to get into. The survey shows exactly what access there is.
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. They’re included in the readings and pictures.
Kitchen extracts in Stockbury
The FSA’s food hygiene register shows about 3 restaurants, cafés and works canteens across Stockbury and its immediate surroundings (about a mile and a half). Each kitchen extract among them can be measured for grease to set the right cleaning interval. Stockbury sits within the area of Kent Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Kitchens in Stockbury get their food hygiene inspections from Maidstone council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Volunteers running a hall kitchen near St Mary Magdalene Church, or anywhere in Stockbury, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Stockbury is KIMS hospital, about 4.5 miles south-west.

What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. We agree a date with you, plan the drive to Stockbury and turn up when the site is quiet.
- We go through any past certificates and reports.
- We follow the extract from canopy to discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

What staff can safely do
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Send TR19 audit reports to your insurer on request
- Store grease readings where your insurer can see them
- Keep grease filters clean and fitted properly
- Don’t box in or cover duct access panels
Where sections couldn’t be reached, the report says where access panels would help. Fitting them before the next clean means the whole system gets done.
Fit access panels where the survey finds sections can’t be reached, so every part of the duct can be cleaned.
