About our TR19 inspection in Grendon Underwood
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. The results show whether the system needs cleaning and how soon. If you have kitchens whose menu or hours have changed and checking the result of a recent clean, we can help.
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.
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. It shows what was done and what, if anything, couldn’t be reached.

What we are called out for in Grendon Underwood
TR19® is the benchmark that insurers, fire officers and EHOs refer to. It isn’t legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and grease in the extract is part of that risk.
Most sites get in touch after spotting one of these:
- Surveys needed before quoting a full clean
- Kitchens whose menu or hours have changed
- Parts of the system left out of past cleans
- An insurer’s request for a TR19 audit
For schools such as Grendon Underwood Combined School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

Grendon Underwood questions
Can school kitchens in Grendon Underwood be cleaned in the holidays?
Yes, and it’s the easiest time to do it. Around Grendon Underwood, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Who carries out food hygiene inspections in Grendon Underwood?
Food hygiene inspections in Grendon Underwood are carried out by Buckinghamshire council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Do you work in Grendon Underwood?
Yes. We cover Grendon Underwood and across Buckinghamshire, within our South East and London area. To book, ring 0345 646 2711 or email us.
Can you work evenings and weekends?
Yes, and it’s often the best time. The visit is timed for when the area isn’t in use, whether that’s late evening, overnight or a weekend.
How often should a kitchen extract be inspected?
We suggest a next test date in every report, based on the readings and how the kitchen is used. The interval should come from a competent person’s risk assessment backed by grease measurement.
What about areas you cannot get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
How long does a TR19 inspection take?
As a guide, it takes a morning or less for one kitchen, more where there are several systems. System size and access decide the rest.

Why act early in Grendon Underwood
A pre-clean survey avoids surprises on the night. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, so the clean covers the whole system. Somewhere as small as Grendon Underwood, losing a kitchen or building to a fault is felt by everyone who uses it.
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.
Why Grendon Underwood businesses choose us
- One number for every site across the South East and London
- A fixed price before any work starts
- Work around your opening hours, with 24/7 emergency cover
- Photo reports with every job
What affects the cost of TR19 inspection
The diagnosis comes before the price. The main factors are:
- Parking and loading at the site
- Whether we need access equipment or extra panels
- Site rules, permits and inductions
- The condition we find in the survey
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.
Asking for a quote
To help us quote quickly, please include:
- Wide photos of the system and the area around it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any previous report or certificate
- The postcode and the type of business
Want a quote for TR19 inspection? Please call 0345 646 2711, or email photos and tell us about the site. We will explain what we’d do and send a fixed quote before you commit to anything.
What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
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 will take a look and send you a fixed quote.
Honest limits
Not every problem is solved by TR19 inspection, and we’d rather say so up front. It won’t put right:
- Heavy deposits found on test, which still need cleaning
- Sections with no access, until panels are fitted
- Fan breakdowns, which need a repair visit
If you’re not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer before you book.
