TR19 inspection for kitchens and businesses in How Green
A grease test measures how thick the grease is inside a kitchen extract system. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. The results show whether the system needs cleaning and how soon. If you have ductwork where grease may be over the TR19 limits and insurers asking for TR19 evidence, we can put it right.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

Grease, kitchens and How Green
Look up How Green on the FSA’s food hygiene register and you’ll find about 4 restaurants, cafés and works canteens in How Green and the streets around it, up to about 1.5 miles out. For any of them with a canopy, measuring grease is better than guessing when to clean. Kitchens in How Green get their food hygiene inspections from Sevenoaks council. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after photos from each clean are a simple way to show the extract is in hand. How Green sits within the area of Kent Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Where a hall near Church of St Peter, or anywhere in How Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Hever Castle is about 0.7 miles south), access may need planning. School kitchens, at schools like Hever Church of England Voluntary Aided Primary School for example, are typically cleaned in the holidays so no lunches are lost.

Managing agents and facilities teams in How Green
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 can quote for the whole system.
We also work for facilities teams across offices, schools and healthcare in How Green and across Kent. Work can be phased by floor, building or site around the people who use them.
Why act early in How Green
Post-clean verification shows whether the system was left the way the certificate says, while there’s still time to put anything right. In a place like How Green, ductwork and fans are easy to forget until something goes wrong.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before we start.
Why How Green businesses choose us
- A single point of contact for sites across the South East and London
- A fixed price before any work starts

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
What a clean will not put right
We’d rather tell you now than book work that won’t help, so here are the limits:
- Fire safety duties beyond the extract system
- The grease itself, which needs a full or spot clean
- Ductwork that was designed or installed badly
If you’re not sure, just call 0345 646 2711 or email us and we will give you a straight answer.
Where we work
- Wet film thickness tests

Common questions in How Green
Is How Green within the area you cover?
Yes, we work in villages as well as towns, and How Green is covered. A survey first, from photos or a visit, means we arrive with the right kit.
Who would carry out a food hygiene inspection at a kitchen in How Green?
Kitchens in How Green are inspected by Sevenoaks 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.
How much notice do you need?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
What grease levels does TR19 allow?
TR19® Grease says grease should not go over a mean of 200 microns between cleans. 500 microns or more at any point calls for immediate spot cleaning.
What does TR19 inspection cost?
Every site is different, so each gets its own fixed quote. To get one, call us on 0345 646 2711 or use the quote form and tell us about the site and its opening hours.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
Do you work out of hours?
Yes, and it’s often the best time. We book the visit for when the area is out of use, whether that is late evening, overnight or a weekend.
What we do, step by step
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Somewhere as small as How Green, the date and timings are agreed with you well before the day.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
- Plan for cooking equipment or plant to be off before we arrive
