How we handle TR19 inspection in Pin Green
A grease test measures how thick the grease is inside a kitchen extract system. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). From the numbers, you can see whether cleaning is due. The work covers access surveys, deposit thickness tests and wet film thickness tests, and common reasons people get in touch are ductwork where grease may be over the TR19 limits and confirming a clean reached the whole system.
For a smaller kitchen near Pin Green, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What a clean will not put right
Not every problem is solved by TR19 inspection, and we’ll tell you before work begins. It doesn’t solve:
- Parts of the duct nobody can reach yet
- Ductwork that was designed or installed badly
- Fire safety duties beyond the extract system
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we’ll tell you honestly.

How the job changes from site to site
Horizontal duct runs
Grease settles on the floor of horizontal ducts as the air cools. Readings are taken along each run through its access panels.
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. We check and test them as part of the inspection.
What affects the quote in Pin Green
The diagnosis comes before the price. The main factors are:
- The number of sites or systems
- Whether it’s a one-off visit or part of a schedule
- Site requirements such as sign-in and permits
- Whether we need access equipment or extra panels
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
Helping us quote
A few details help us quote accurately. With your enquiry, please include:
- A few general shots of the system
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
Quotes are quick. Send a few details and photos, 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.
Common problems we fix in Pin Green
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. The old cleaning schedule may not match the kitchen any more.
Most sites get in touch after spotting one of these:
- An insurer’s request for a TR19 audit
- Missing TR19 certificates or history
- Kitchens whose menu or hours have changed
- Post-clean verification after another contractor’s clean
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Aston Bury is about 3 miles south-east), access may need planning.

Common questions in Pin Green
Can you get to a site in Pin Green?
Yes, we work in villages as well as towns, and Pin Green is covered. Photos of the system and directions to the site help us plan the visit.
Which fire authority looks after Pin Green?
It’s Hertfordshire Fire and Rescue Service, which covers Pin Green. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What is grease thickness testing?
Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. Each reading is recorded in microns.
What does TR19 mean?
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 is not law, but it’s the benchmark.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
What should I send you?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
How much does TR19 inspection cost in Pin Green?
It depends on the site, so we quote each one individually. To get one, ring 0345 646 2711 or use the quote form with the site type, opening hours and a few photos.
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare in Pin Green and across Hertfordshire. Work can be phased by floor, building or site around the people who use them.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Why act early in Pin Green
If a kitchen in Pin Green has been cleaned on the same calendar for years, there’s no way to know if that interval is right without measuring. Testing gives you the evidence to set it properly. It’s easy to lose track of when the work was last done on a quieter site.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and why the quote is fixed before work begins.

Each kitchen extract among them can be measured for grease to set the right cleaning interval. Pin Green sits within the area of Hertfordshire Fire and Rescue Service.

Before-and-after pictures from each clean are a simple way to show the extract is in hand.
