TR19 inspection for kitchens and businesses in Walter's Ash
Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. A TR19 audit sets out the system’s condition, with readings and photos, for sites in Walter's Ash and the rest of Buckinghamshire. We are often asked to deal with uncertainty over how often to clean and pre-clean surveys before a first TR19 clean, on wet film thickness tests, insurer audits and deposit thickness tests.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Fixed quotes for TR19 inspection in Walter's Ash
Some jobs are bigger than they look, and some smaller. What affects the quote:
- A single visit or a regular plan
- Travel, parking and unloading
- Any permits to work or inductions
- Working hours and out-of-hours timing
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call us on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
What to send for a quote
We can often survey from pictures. The most useful are:
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- Wide photos of the system and the area around it
- Your last certificate, test record or report
We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711 or email us.
Part by part
Schools, hospitals and care homes
Education kitchens need TR19 inspections like any other. Testing shows whether the interval suits.
Extract fan and discharge
The discharge at the end of the system is checked as well, as grease can build up there too.
Staff cleaning versus specialist work
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 they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.

TR19 inspection in Walter's Ash: the local picture
Food Standards Agency records include about 3 pubs and bars within 1.5 miles or so of the middle of Walter's Ash. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. The fire and rescue service for Walter's Ash is 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. Environmental health officers from Buckinghamshire council inspect food businesses in Walter's Ash. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you run a church or community hall kitchen, near Church of St Botolph or elsewhere in Walter's Ash, its extract still collects grease from every lunch and event. Healthcare kitchens, like those at hospitals such as Wycombe Hospital (about 3.7 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Your questions about TR19 inspection in Walter's Ash
Which council inspects kitchens in Walter's Ash?
The local authority for Walter's Ash is Buckinghamshire council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Which fire service covers Walter's Ash?
That is Buckinghamshire Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How long does grease testing 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.
When should we have our next grease test?
Enough to be sure grease stays within the TR19® Grease figures between cleans. The readings themselves tell you if the interval needs to change.
Do you carry out TR19 audits for insurers?
Yes. Insurers often want evidence the extract is managed to TR19®, and an audit report gives you that, with recommendations where something needs doing.
What should I send you?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
What happens on a pre-clean survey?
A survey finds out how the system is laid out, how dirty it is and what can be reached, before anyone starts cleaning. Any access problems are flagged ahead of the clean.
When something else is needed
TR19 inspection can’t fix everything, and we’d rather say so up front. It does not solve:
- Sections with no access, until panels are fitted
- A faulty or failing extract fan
- The grease itself, which needs a full or spot clean
If you are not sure, just call us on 0345 646 2711, or email photos and we will give you a straight answer before booking.
Parts of the system we cover
- Wet film thickness tests
- Deposit thickness tests
- Post-clean checks
- Pre-clean surveys
- Insurer audits
- Access surveys
What we’re called out for in Walter's Ash
You cannot judge grease thickness by eye. A system can look clean at the filters and be heavily coated further in, so readings are the reliable guide.
These are the problems we see most often:
- An insurer’s request for a TR19 audit
- Missing TR19 certificates or history
- Systems that need surveying before cleaning
- Parts of the system left out of past cleans
Bursars and site managers at schools such as Naphill and Walters Ash School tend to book extract cleaning for when the kitchen is empty.
Questions to ask before you book
- Whether inaccessible sections are listed on the report
- Whether the price is fixed
- How VAT is shown on the quote
