The process
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes a morning or less for one kitchen, more where there are several systems. In a small place like Shreding Green, the journey is planned ahead and the visit arranged around the site’s hours.
- We agree a time when the kitchen is closed or quiet.
- Every part of the system is examined, end to end.
- Grease thickness is measured at set points by WFTT or DTT.
- Each test point and any access problems are photographed.
- The findings go into a report with readings, photos and a recommended next clean.
Before we arrive
- Mention any parking or loading restrictions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about permits to work or site inductions

Advice
TR19 inspection in Shreding Green
Under TR19® Grease, the mean grease thickness should stay at or below 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. The work covers deposit thickness tests, wet film thickness tests and insurer audits, and people most often call us about kitchens whose menu or hours have changed and missing TR19 certificates or history.
In a small place like Shreding Green, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Honest limits
We will always give you a straight diagnosis, so here’s what TR19 inspection will not do:

- Ductwork that was designed or installed badly
- Sections with no access, until panels are fitted
If you are not sure, just phone us on 0345 646 2711 or send us an email and we’ll give you a straight answer.

Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Buckinghamshire. Work can be phased by floor, building or site to keep disruption down.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Part by part
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. They’re included in the readings and photos.
Canopy and plenum
The plenum behind the filters can carry a lot of grease. Readings and pictures are taken in the plenum as part of every survey.
What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
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.
What TR19 inspection looks like in Shreding Green
Food Standards Agency data counts about 18 restaurants, cafés and works canteens and about 14 takeaways in Shreding Green and the streets around it, up to about 1.5 miles out. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. It’s Buckinghamshire council that sends environmental health officers to food businesses in Shreding Green. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Shreding Green sits within the area of Buckinghamshire 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.
Commuter trade near Langley station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Where a hall near Church of St Peter, or anywhere in Shreding Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Common questions in Shreding Green
Do you work in villages like Shreding Green?
Yes, Shreding Green is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Do you clean school canteen extracts around Shreding Green out of term?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 6 schools and colleges with food registrations within roughly a mile and a half of Shreding Green. Booking early in the term gives the best choice of holiday dates.
What if parts of the system can’t be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
How often should grease be tested?
We suggest a next test date in every report, taking the readings and the kitchen’s hours into account. A risk assessment based on measured grease should set the interval.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
What do the grease readings need to be?
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. We show your readings against those figures.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
What is post-clean verification?
Verification means repeat readings and pictures once the clean is done. The report flags anything missed.
Common problems we fix in Shreding Green
Grease in a duct is flammable fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Knowing how much there is lets you act before it becomes a hazard.
If you notice any of these, it’s worth a diagnosis:
- Sites with gaps in their extract records
- Checking the result of a recent clean
- Extracts that may be over the 200 micron mean
- Extracts that have never been grease tested
If you run catering at a healthcare site, such as a hospital like Wexham Park Hospital about 2.3 miles north-west, the extract may need cleaning more often than a part-time kitchen.
Questions to ask before booking
- How areas they cannot reach will be recorded
- How VAT is shown on the quote
