TR19 inspections and grease testing in Chilton, Buckinghamshire
For TR19 inspections, grease thickness testing, pre-clean surveys and post-clean verification in Chilton, one call is all it takes, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Checking the result of a recent clean
- Missing access panels found on survey
- Heavy grease suspected in the plenum or ducts
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep canopy edges and gutters wiped down
- File every inspection report with your certificates
- Don’t box in or cover duct access panels
- Report grease dripping from the canopy
For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.
When cooking hours or the menu change, check the interval still fits. A quick grease test answers the question.
About our TR19 inspection in Chilton
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Testing is how you know where your system stands. Typical jobs include missing TR19 certificates or history and surveys needed before quoting a full clean, on wet film thickness tests, deposit thickness tests and insurer audits.
Work in a small place like Chilton starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
What we do, step by step
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a morning or less for one kitchen, more where there are several systems. In a small place like Chilton, the journey is planned ahead and the visit arranged around the site’s hours.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- 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
- Let us know when the site is closed or quiet
- Have your last certificate or report to hand
- Name a contact who can let us in at the agreed time
Get a fixed quote
For a fixed quote, call us on 0345 646 2711 or drop us a line 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. We normally come back within one working day.

Signs you need TR19 inspection in Chilton
Some parts of a system are hard to reach, and grease can be missed there clean after clean. A survey finds the sections that can’t be reached, so the gaps can be closed.
Keep an eye out for any of the following:
- Post-clean verification after another contractor’s clean
- Kitchens whose menu or hours have changed
- Extracts that have never been grease tested
- Insurers asking for TR19 evidence
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Waddesdon Manor is about 4.2 miles north-east), access may need planning.
Before you book anyone
- Whether the figure could change on the day
- Proof of insurance
- How areas they can’t reach will be recorded

Chilton questions
Which fire service covers Chilton?
Buckinghamshire Fire and Rescue Service is the fire and rescue service for Chilton. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you work overnight in Chilton?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. When you ring 0345 646 2711 or email us, mention when the site is quiet.
How often should a kitchen extract be inspected?
Often enough to know the mean stays under 200 microns between cleans. The readings themselves tell you if the interval needs to change.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
What about areas you cannot get to?
We record them on the report, with photos where possible, and we explain what access is needed, for example new access panels.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and pictures.
When something else is needed
Before booking, it helps to know what’s not included:
- Heavy deposits found on test, which still need cleaning
- Hidden runs that need access panels first
- Fire safety duties beyond the extract system
If you are not sure, just ring 0345 646 2711 or email us and we’ll give you a straight answer.

What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Grease, kitchens and Chilton
It’s Buckinghamshire council that sends environmental health officers to food businesses in Chilton. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. At about 44 miles from central London, Chilton sits well inside the area we cover. The visit is fixed around your opening hours, not ours.
Church and community hall kitchens, near Parish Church of St Mary or anywhere around Chilton, are easy to forget, but their extracts collect grease like any other. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Thame Community Hospital is the nearest hospital to Chilton, about 3.8 miles south.
Chilton is about 4 miles north of Thame, in Buckinghamshire. We provide TR19 inspection for commercial premises of every kind in Chilton and the rest of Buckinghamshire.
