How we handle TR19 inspection in Ashendon
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. Grease testing shows which side of those lines you are on. The work covers deposit thickness tests, insurer audits and access surveys, and the jobs we see most are systems that need surveying before cleaning and parts of the system left out of past cleans.
In a village or hamlet like Ashendon, the kitchens that need extract cleaning are typically 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.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How the job changes from site to site
Extract fan and discharge
The extract fan and its housing collect grease too. We check and test them as part of the inspection.
Canopy and plenum
Clean-looking filters do not mean a clean plenum. That is why we test behind them.

How we price TR19 inspection
The diagnosis comes before the price. We look at:
- Working hours and out-of-hours timing
- Parking and loading at the site
- Any permits to work or inductions
- How easy every part is to reach
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 are not sure what’s needed, give us a ring on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.
Helping us quote
Before you ask for a quote, gather:
- Your last certificate, test record or report
- The times we could work without disrupting the site
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
TR19 inspection around Ashendon
Ashendon is covered by Buckinghamshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Ashendon, about 44 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.
Church and community hall kitchens, near Parish Church of St Mary the Virgin or anywhere around Ashendon, are easy to forget, but their extracts collect grease like any other. If you run catering at a historic house or estate in the area (Waddesdon Manor is about 2.3 miles north-east), event kitchens in older buildings often have awkward duct runs that need planning.
Ashendon is about 5 miles north of Thame, in Buckinghamshire. Whatever kind of site you run in Ashendon, TR19 inspection is something we can help with. We can work out of hours so the site keeps running. We cover 263 places across Buckinghamshire, large and small. Our Oxford page covers sites nearby, about 12 miles away.

When something else is needed
A few issues sit outside what this work can do:

- Hidden runs that need access panels first
- Removing the grease, which is a separate clean

Ashendon questions
Is Ashendon within the area you cover?
Yes, Ashendon is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Which fire authority looks after Ashendon?
Fire safety enforcement in Ashendon is handled by Buckinghamshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Can you work evenings and weekends?
Yes, and that’s how we prefer to work. The visit is timed for when the area is not in use, such as late evening, overnight or a weekend.
How long does a TR19 inspection take?
Expect it to take a couple of hours for a typical kitchen extract system. We fit it around when the kitchen is closed or quiet.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What is a WFTT or DTT grease test?
The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. We take readings at set points from canopy to fan.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What we are called out for in Ashendon
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. A cleaning interval set years ago may no longer fit.
Keep an eye out for any of the following:
- Heavy grease suspected in the plenum or ducts
- An insurer’s request for a TR19 audit
- Systems that need surveying before cleaning
- Kitchens taken over with no cleaning records
If you run catering at a healthcare site, such as a hospital like St John's Hospital about 4.6 miles east, the extract may need cleaning more often than a part-time kitchen.
Questions to ask before you book
- Whether the whole system is included, or only the parts that are easy to reach
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether they recommend a next date
- Whether the quote is based on a survey or pictures
The process
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. On site, the work takes around an hour or two per canopy and duct system. Pictures of the system and its access let us plan the work in Ashendon before we set off.
- Post-clean verification is booked once the clean is done.
- 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
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
- Clear the space around the work
Getting a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or send details by email.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Facilities teams in offices, schools and healthcare sites book us too in Ashendon and across Buckinghamshire. Larger estates can be phased building by building to keep disruption down.
