TR19 inspection in Asheridge, done properly
Post-clean verification is a check carried out once the cleaning is done, with fresh grease readings, pictures and a look at the areas that were cleaned. It gives you evidence of how the system was actually left. The work covers post-clean checks, pre-clean surveys and insurer audits, and common reasons people get in touch are insurance renewals needing proof of TR19 cleaning and missing TR19 certificates or history.
In a small place like Asheridge, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What TR19 inspection looks like in Asheridge
The FSA’s data shows about 3 bars, pubs and nightclubs registered in Asheridge and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Asheridge, food businesses are inspected by environmental health officers from Buckinghamshire council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Asheridge sits within the area of 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.
Historic houses near Asheridge, such as Cholesbury Manor House about 1.7 miles north, are a reminder that older buildings with event kitchens can have long, awkward duct routes. Where a hall near St John's Church, or anywhere in Asheridge, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Advice
Questions from Asheridge
Who inspects food businesses in Asheridge?
The local authority for Asheridge is Buckinghamshire council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Who enforces fire safety at workplaces in Asheridge?
Asheridge is in the area of Buckinghamshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you work in Asheridge?
Yes. Asheridge is part of the area we cover, as part of our area across London and the South East.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
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.
Can you quote from pictures?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Do we have to follow TR19 by law?
No. TR19® isn’t law; it’s BESA’s specification. The law is the Fire Safety Order 2005, under which the responsible person must manage fire risk, and TR19® is what insurers and fire officers look to.
What do the grease readings need to be?
Between cleans, the mean should stay at 200 microns or below, and anywhere at 500 microns or more needs spot cleaning straight away.
How we price TR19 inspection
We don’t publish a price list, because no two systems are the same. The quote depends on:
- Site requirements such as sign-in and permits
- Whether several sites go on one quote
- When the work can happen, such as evenings, overnight or weekends
- What state the system is in
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before work begins.
What to send for a quote
When you contact us, these details help:
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
If you need TR19 inspection in Asheridge, call 0345 646 2711 or use the quote form. Let us know the site type and the opening hours, and send pictures or your last report if you can. We normally send a fixed quote within one working day.
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too across Buckinghamshire. Work can be phased by floor, building or site to keep disruption down.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Aftercare tips
Here’s the after-treatment advice, in brief:
- Keep the route to access panels clear
- Mention new equipment or longer hours at the next test
- Store grease readings where your insurer can see them
- Clean grease off the canopy between professional cleans
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can quote to do it.
Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.
Common problems we fix in Asheridge
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.
What we’re most often called out for:
- Uncertainty over how often to clean
- Missing access panels found on survey
- Sites with gaps in their extract records
- Surveys needed before quoting a full clean
Healthcare kitchens, like those at hospitals such as Chiltern Hospital (about 3.7 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.
