How we handle TR19 inspection in High Wycombe
Post-clean verification is a check carried out once the cleaning is done, with new readings and photos of the cleaned areas. It shows whether the system was left in the condition the paperwork describes. The work covers access surveys, pre-clean surveys and deposit thickness tests, and common reasons people get in touch are uncertainty over how often to clean and an insurer’s request for a TR19 audit.
Many kitchens in a town like High Wycombe were fitted into buildings built for something else, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Sections we cannot reach are listed on the report, and access panels can be added.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

High Wycombe: your questions answered
Who would carry out a food hygiene inspection at a kitchen in High Wycombe?
In High Wycombe, it’s Buckinghamshire council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you clean school canteen extracts around High Wycombe out of term?
Yes, out-of-term visits are normal for schools. There are about 29 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of High Wycombe. Tell us your holiday dates and we will book the visit for when the site is empty.
What does TR19 inspection cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, normally ready within one working day.
What do the grease readings need to be?
Between cleans, the mean should stay at 200 microns or below, with 500 microns or more anywhere needing immediate spot cleaning.
How much time does an inspection need?
It takes a couple of hours for a typical kitchen extract system. We fit it around when the kitchen is closed or quiet.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we’ll quote them together.
What is a WFTT or DTT grease test?
It’s a measurement of how much grease is coating the inside of the extract, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). Each reading is recorded in microns.
Can you quote from photos?
Normally, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we typically come back within one working day. If pictures aren’t enough, we will survey first.
How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes an hour or two for a single kitchen, longer for a large or complex system. Parking in a town like High Wycombe is normally straightforward, so the main questions are access and timing.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- We report the findings and flag any areas that need more work.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Mention any parking or loading restrictions
- Make sure someone can let us in and lock up afterwards
Ask for a quote
For a fixed quote, give us a ring on 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. We typically come back within one working day.

Common problems we fix in High Wycombe
Kitchens change: a new menu, longer hours or more frying can all add grease. The old cleaning schedule may not match the kitchen any more.
Any of these means the system needs a check-up:
- Kitchen extract systems with no recent grease readings
- Pre-clean surveys before a first TR19 clean
- Post-clean verification after another contractor’s clean
- Insurers asking for TR19 evidence
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to High Wycombe is Hospital of St John the Baptist, about within half a mile south-east.
Questions to ask before you book
- Whether the figure could change on the day
- How VAT is shown on the quote
- What happens if part of the system can’t be accessed
- How they set the interval to the next visit
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Book the next test on the date in the report
- Clean grease off the canopy between professional cleans
- Share inspection reports with your insurer or broker when asked
- Mention new equipment or longer hours at the next test
For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.
Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.
Why act early in High Wycombe
Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Left alone, grease keeps building between cleans. If an inspection, an insurer’s survey or a fire risk assessment is coming up in High Wycombe, having the work done and recorded first helps.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, phone us on 0345 646 2711, or email photos for straight advice and a fixed quote.

What affects the quote in High Wycombe
Every site gets its own quote. This is what makes a difference:
- Where the site is and how we reach it
- How easy every part is to reach
- Any permits to work or inductions
- The size of the system
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
Helping us quote
We can often survey from photos. The most useful are:
- A few general shots of the system
- The paperwork from the last visit, if you have it
- The postcode and the type of business
- The times we could work without disrupting the site
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before work begins.
What TR19 inspection cannot fix
In fairness, there are a few things this work won’t fix:
- The legal duty, which stays with the responsible person
- Heavy deposits found on test, which still need cleaning
- Hidden runs that need access panels first
If in doubt, ring 0345 646 2711 or send us an email and we’ll say what we think.
Where we work
- Post-clean checks
- Deposit thickness tests
- Insurer audits

High Wycombe kitchens: local notes
According to Food Standards Agency records, there are about 22 pubs and bars and about 5 hotels and guest houses across High Wycombe and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Food hygiene inspections in High Wycombe are the job of Buckinghamshire council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for High Wycombe is Buckinghamshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
A hall kitchen that only cooks for events, whether near Church of All Saints or elsewhere in High Wycombe, still needs its extract cleaned, just less often. Term dates shape school work: for a school like Hamilton Academy, an extract clean fits neatly into a half-term or summer break.

What your team can do, and what needs us
If your staff spot something 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.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
