TR19 inspection for kitchens and businesses in Roke
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). The results show whether the system needs cleaning and how soon. We are often asked to deal with ductwork where grease may be over the TR19 limits and an insurer’s request for a TR19 audit, across access surveys, insurer audits and wet film thickness tests.
Somewhere as small as Roke, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What the work involves, part by part
Extract fan and discharge
We look at where the extract discharges outside, since grease reaches the very end of the system.
Canopy and plenum
Filters can look fine while the plenum behind them is heavily coated. So we measure behind the filters, not just in front.
How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a couple of hours for a typical kitchen extract system. Pictures of the system and its access let us plan the work in Roke before we set off.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- Grease readings are taken and photos recorded.
- We report back with readings and a fixed quote.
Getting ready for the visit
- Let us know about parking and loading
- Name a contact who can let us in at the agreed time
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
To get a fixed quote, ring 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You will usually have a quote within one working day.
Related advice
Do you need TR19 inspection in Roke?
Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Measuring it is the first step to keeping it under control.
Keep an eye out for any of the following:
- Post-clean verification after another contractor’s clean
- Systems that need surveying before cleaning
- Cleaning intervals that may not suit the kitchen
- Kitchen extract systems with no recent grease readings
Brightwell Manor, about 3.4 miles south-west, is one of the historic houses near Roke; if you run event catering at a venue like that, cleans can be booked between functions.

Questions from Roke
Which fire authority looks after Roke?
Roke is in the area of Oxfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can you get to a site in Roke?
Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
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.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Do you carry out TR19 audits for insurers?
Yes. Insurers often want evidence the extract is managed to TR19®, and an audit report gives you that, with recommendations where something needs doing.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What TR19 inspection cannot fix
To be straight with you, there are a few things this work will not fix:
- Hidden runs that need access panels first
- Mechanical faults in the extract
- Removing the grease, which is a separate clean
Not sure which it is? You can call 0345 646 2711, or send details by email and we will tell you honestly before booking.
What the work covers
- Wet film thickness tests
- Pre-clean surveys
- Insurer audits
- Post-clean checks
- Deposit thickness tests
- Access surveys
Leave it or put it right?
Without readings, you’re guessing when to clean. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, which you will not know without measuring. Out of sight is the usual reason a rural system goes too long without attention.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.

Looking after it afterwards
To keep the system working properly between visits:
- Share inspection reports with your insurer or broker when asked

- Wipe the canopy surfaces regularly
- Keep to the recommended interval
Any access problems we found are listed with a suggested fix. With panels fitted, the next clean can cover every section.
Keep all TR19 records together so the history is easy to show.
