How we handle TR19 inspection in Charlton-on-Otmoor
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. Testing is how you know where your system stands. The work covers pre-clean surveys, deposit thickness tests and wet film thickness tests, and people most often call us about confirming a clean reached the whole system and missing access panels found on survey.
For a kitchen in or near Charlton-on-Otmoor, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

When to call us in Charlton-on-Otmoor
You cannot judge grease thickness by eye. Clean filters can hide a heavy layer behind them, so readings are the reliable guide.
What we are most often called out for:
- Missing TR19 certificates or history
- Surveys needed before quoting a full clean
- Kitchen extract systems with no recent grease readings
- Uncertainty over how often to clean
Bursars and site managers at schools such as Charlton-on-Otmoor Church of England Primary School tend to book extract cleaning for when the kitchen is empty.

Common questions in Charlton-on-Otmoor
Do you cover smaller places like Charlton-on-Otmoor?
Yes. Charlton-on-Otmoor 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.
Which fire service covers Charlton-on-Otmoor?
Oxfordshire Fire and Rescue Service is the fire and rescue service for Charlton-on-Otmoor. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
How much does TR19 inspection cost in Charlton-on-Otmoor?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we will typically reply within one working day.
Keeping the system healthy
After the visit, a few habits help the work last:
- Keep the route to access panels clear
- Report grease dripping from the canopy
- Flag changes in how much frying the kitchen does
- Keep TR19 certificates, readings and reports together
Any access problems we found are listed with a suggested fix. Fitting them before the next clean means the whole system gets done.
Keep filters clean and in place. Gaps around filters let grease get past them.
The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Pictures of the system and its access let us plan the work in Charlton-on-Otmoor before we set off.
- First we look at the system’s cleaning history, if there is one.
- The layout is traced from the canopy to the discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
Getting ready for the visit
- Clear the space around the work
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
