TR19 inspection in Wycombe Marsh, done properly
BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Those are minimums, and grease readings help set the real interval. The work covers wet film thickness tests, pre-clean surveys and deposit thickness tests, and common reasons people get in touch are parts of the system left out of past cleans and post-clean verification after another contractor’s clean.
In a village or hamlet like Wycombe Marsh, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

How we price TR19 inspection
Every site gets its own quote. These are the things that affect it:
- How many systems or sites are involved
- What state the system is in
- Where the site is and how we reach it
- One-off work versus a regular cycle
What you pay depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
Helping us quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711 or send us an email.
What TR19 inspection looks like in Wycombe Marsh
Look up Wycombe Marsh on the FSA’s food hygiene register and you will find about 88 restaurants, cafés and works canteens and about 44 takeaways and sandwich shops within roughly a mile and a half of the centre of Wycombe Marsh. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. Wycombe Marsh is covered by Buckinghamshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Kitchens in Wycombe Marsh get their food hygiene inspections from Buckinghamshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
Church and community hall kitchens, near Church of St Anne or anywhere around Wycombe Marsh, are easy to forget, but their extracts collect grease like any other. A hospital like Hospital of St John the Baptist, about 1.2 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run catering at a historic house or estate in the area (Hughenden Manor is about 2.8 miles north-west), event kitchens in older buildings often have awkward duct runs that need planning.
Wycombe Marsh is about 1 mile south-east of High Wycombe, in Buckinghamshire. Every kind of commercial site in Wycombe Marsh, we can take on TR19 inspection. Visits can be booked for evenings, overnight or weekends so the site keeps running. Our area takes in 263 places across Buckinghamshire, from busy centres to quieter spots. There’s also a page for Reading, about 16 miles away.

Honest limits
To be straight with you, some problems need a different fix:
- Ductwork that was designed or installed badly
- Parts of the duct nobody can reach yet
- Heavy deposits found on test, which still need cleaning
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we will tell you honestly before you book.
Parts of the system we cover
- Wet film thickness tests
- Pre-clean surveys
- Post-clean checks
- Deposit thickness tests
- Insurer audits
- Access surveys
What the work involves, part by part
Restaurants, pubs and hotels
We test between services, early in the morning or after close so the kitchen keeps cooking.
Extract fan and discharge
The discharge at the end of the system is checked as well, as grease can build up there too.
Wycombe Marsh questions
Which fire authority looks after Wycombe Marsh?
Wycombe Marsh is in the area of Buckinghamshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you cover smaller places like Wycombe Marsh?
Yes. Wycombe Marsh is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. We normally quote within one working day, and emergencies are covered by our 24/7 line.
Can you work evenings and weekends?
Yes, and that is how we prefer to work. We book the visit for when the area is out of use, whether that is late evening, overnight or a weekend.
What grease levels does TR19 allow?
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. Our report sets your readings against both.
What is grease thickness testing?
Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. The results are given in microns.
How long does grease testing take?
Testing takes an hour or two for a single kitchen, longer for a large or complex system. Sites with several canopies take longer, and you can phone us on 0345 646 2711 or use the quote form to book it in.
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Facilities teams in offices, schools and healthcare sites book us too in Wycombe Marsh and across Buckinghamshire. Work can be phased by floor, building or site around the people who use them.
Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Wipe the canopy surfaces regularly
- Store grease readings where your insurer can see them
- Don’t box in or cover duct access panels
- Never cook with filters missing
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can arrange it.
Test grease regularly instead of relying on the calendar. It shows if build-up is speeding up.
