TR19 inspection for kitchens and businesses in Wallingford
After a clean, post-clean verification checks the result, with new readings and pictures of the cleaned areas. It gives you evidence of how the system was actually left. If you have pre-clean surveys before a first TR19 clean and ductwork where grease may be over the TR19 limits, we can put it right, from deposit thickness tests, post-clean checks and wet film thickness tests onwards.
In a smaller place like Wallingford, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Wallingford questions
Do you work in villages like Wallingford?
Yes. Villages and rural sites across the South East are part of our work, Wallingford included. A survey first, from photos or a visit, means we arrive with the right kit.
Can you work in Wallingford outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What is a WFTT or DTT grease test?
The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. We take readings at set points from canopy to fan.
How much does TR19 inspection cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, usually ready within one working day.
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.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Will you produce a report for our insurer?
Yes, anywhere in the area we cover. Share the insurer’s request so the report addresses it.
The process
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a morning or less for one kitchen, more where there are several systems, and the area is cleaned down before we leave. Getting to the system matters more than parking in a place like Wallingford, so let us know how to reach it.
- First we look at the system’s cleaning history, if there is one.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- We measure the grease and photograph each point.
- We report back with readings and a fixed quote.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Tell us about site rules, permits or sign-in
- Mention any parking or loading restrictions

What the work involves, part by part
Vertical risers
Risers in multi-storey buildings can pass through other areas, so we arrange access ahead of time.
Canopy and plenum
Behind the filters, the plenum catches plenty of grease. Readings and pictures are taken in the plenum as part of every survey.
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
What happens if it’s left?
Catching heavy deposits early keeps the fix small. Ignored, the layer only gets thicker. A planned visit to Wallingford fits your hours; an emergency does not.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before we start.

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Look out for grease drips round the canopy edge
- Mention new equipment or longer hours at the next test
- Never cook with filters missing
- Wipe the canopy surfaces regularly
The audit report is set out to pass straight to your insurer or broker, including readings, pictures and any inaccessible sections.
Keep all TR19 records together so the history is easy to show.
What affects the cost of TR19 inspection
There’s no set price list, because no two systems are the same. What we look at:
- What state the system is in
- Access, including roofs, risers and ceiling voids
- Working hours and out-of-hours timing
- How big the system is
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.
Asking for a quote
When you call or email, these details help:
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- Photos showing the whole system and its surroundings

Wallingford kitchens: local notes
The FSA’s data shows about 9 pubs, bars and clubs and about 3 hotels, B&Bs and guest houses registered within roughly a mile and a half of the centre of Wallingford. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Food hygiene inspections in Wallingford are the job of South Oxfordshire council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked. Wallingford sits within the area of Oxfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
For schools such as Fir Tree Junior School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Brightwell Manor is about 1.7 miles north-west), access may need planning. A hall kitchen that only cooks for events, whether near St Mary-le-More or elsewhere in Wallingford, still needs its extract cleaned, just less often.
