TR19 inspection in Knapp
Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. From the numbers, you can see whether cleaning is due. The work covers access surveys, pre-clean surveys and insurer audits, and common reasons people get in touch are insurers asking for TR19 evidence and missing access panels found on survey.
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.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Aftercare tips
To keep the system working properly between visits:
- Keep the route to access panels clear
- Send TR19 audit reports to your insurer on request
- Never cook with filters missing
- Tell us if menus or opening hours change
After the inspection, we send a report showing each reading, its location and photos. File it alongside your TR19 certificates.
Keep filters clean and in place. Gaps around filters let grease get past them.
What the work involves, part by part
Extract fan and discharge
The extract fan and its housing collect grease too. We check and test them as part of the inspection.
Restaurants, pubs and hotels
Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, and readings show whether that is enough.

Common problems we fix in Knapp
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. It isn’t legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and in a kitchen that means keeping grease under control.
Clients typically contact us when they notice something like this:
- Ductwork where grease may be over the TR19 limits
- Cleaning intervals that may not suit the kitchen
- Surveys needed before quoting a full clean
- Missing access panels found on survey
If you run a church or community hall kitchen, near Church of St Mark or elsewhere in Knapp, its extract still collects grease from every lunch and event.
Questions to ask before booking
- What records you’ll receive afterwards
- Whether the figure could change on the day
- How they set the interval to the next visit
- Whether they’re fully insured
The process
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Somewhere as small as Knapp, the date and timings are agreed with you well before the day.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Clear the space around the work
- Dig out any earlier paperwork for the system

What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Knapp: your questions answered
Do you clean school canteen extracts around Knapp out of term?
Yes, out-of-term visits are normal for schools. Around Knapp, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you phone us on 0345 646 2711 or drop us a line, and we will fit the work in.
Can the work in Knapp be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Knapp needn’t be disturbed. Let us know the hours you’re closed and we will book within them.
How long does a TR19 inspection take?
An inspection takes a couple of hours for a typical kitchen extract system. Large or multiple systems take longer, so call 0345 646 2711, or send details by email and we will plan it.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Do you look at the system first?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
What about areas you can’t get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
At what point does grease need cleaning?
Two figures matter: a mean of no more than 200 microns between cleans, and 500 microns at any single point, which needs immediate spot cleaning. Our report sets your readings against both.
Honest limits
A few issues sit outside what this work can do:
- Sections with no access, until panels are fitted
- Removing the grease, which is a separate clean
- Fan breakdowns, which need a repair visit
If in doubt, phone us on 0345 646 2711, or send details by email and we will say what we think before you book.

TR19 inspection in Knapp: the local picture
According to Food Standards Agency records, there are about 5 bars, pubs and nightclubs within 1.5 miles or so of the middle of Knapp. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. In Knapp, food businesses are inspected by environmental health officers from Test Valley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Hampshire and Isle of Wight Fire and Rescue Service covers Knapp. 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 Romsey Community Hospital (about 2.9 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Term dates shape school work: for a school like Ampfield Church of England Primary School, an extract clean fits neatly into a half-term or summer break.

What happens if it’s left?
A pre-clean survey avoids surprises on the night. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, and the quote reflects the real job. It’s worth booking a check, because nobody sees inside a duct day to day.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.
