TR19 inspection for kitchens and businesses in Knatts Valley
Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). The results show whether the system needs cleaning and how soon. If you have insurance renewals needing proof of TR19 cleaning and extracts that may be over the 200 micron mean, we can put it right.
In a village or hamlet like Knatts Valley, the kitchens that need extract cleaning are usually 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.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Kitchen extracts in Knatts Valley
Look up Knatts Valley on the FSA’s food hygiene register and you’ll find about 4 cafés, restaurants and staff canteens across Knatts Valley and its immediate surroundings (about a mile and a half). A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Food hygiene inspections in Knatts Valley are the job of Sevenoaks council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand. Fire safety in Knatts Valley falls to 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.
Healthcare kitchens, like those at hospitals such as Sevenoaks Hospital (about 3.9 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Church and community hall kitchens, near Church of Saint Mary the Virgin or anywhere around Knatts Valley, are easy to forget, but their extracts collect grease like any other. If you look after a school kitchen, at a school such as West Kingsdown CofE VC Primary School or anywhere near Knatts Valley, the holidays are the usual time for a TR19® clean.

Aftercare tips
To keep the system working properly between visits:
- Mention new equipment or longer hours at the next test
- Book the next test on the date in the report
- Keep grease filters clean and fitted properly
- Have the latest report ready for insurance renewals
You get a report with the grease readings, where they were taken and photos of each point. File it alongside your TR19 certificates.
Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.
Knatts Valley questions
Who enforces fire safety at workplaces in Knatts Valley?
That’s Kent Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Will you come out to Knatts Valley?
Yes, we work in villages as well as towns, and Knatts Valley is covered. A survey first, from photos or a visit, means we arrive with the right kit.
What is post-clean verification?
Verification means repeat readings and photos once the clean is done. Any areas that weren’t cleaned properly are flagged.
Is there a survey before the work?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
What information do you need?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we are fully insured.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How often should grease be tested?
Often enough to know the mean stays under 200 microns between cleans. If readings rise, the interval should shorten.
What the work involves, part by part
Horizontal duct runs
Flat duct runs collect grease along their base. Readings are taken along each run through its access panels.
Extract fan and discharge
The extract fan and its housing collect grease too. We check and test them as part of the inspection.
What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes an hour or two for a single kitchen, longer for a large or complex system. Photos of the system and how to reach it help us plan a visit to Knatts Valley.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about parking and loading
- Find the previous report, if there is one
Getting a quote
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before we start.
Advice
In-house cleaning or a specialist?
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.
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 grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

When something else is needed
TR19 inspection can’t fix everything, and we’d rather say so up front. It will not put right:
- The grease itself, which needs a full or spot clean
- The responsible person’s own fire risk assessment
- Mechanical faults in the extract
Not sure which it is? You can call us on 0345 646 2711, or email photos and we will tell you honestly.
