How we handle TR19 inspection in Charvil
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Without it, a claim can be refused or reduced. Our TR19 audits give sites in Charvil and across Wokingham a clear record of the system’s condition. The work covers post-clean checks, deposit thickness tests and pre-clean surveys, and people most often call us about uncertainty over how often to clean and surveys needed before quoting a full clean.
In a smaller place like Charvil, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Signs you need TR19 inspection in Charvil
As hot, greasy air travels up the duct, it cools and leaves a film behind. It often collects where nobody can see it: the plenum, bends and horizontal runs.
Most sites get in touch after spotting something like this:
- Confirming a clean reached the whole system
- Cleaning intervals that may not suit the kitchen
- Surveys needed before quoting a full clean
- Extracts that may be over the 200 micron mean
Term dates shape school work: for a school like Waingels College, an extract clean fits neatly into a half-term or summer break.
What your quote should include

- Whether they’re fully insured
- Whether the quote is based on a survey or pictures
- Whether the figure could change on the day
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
The process
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a couple of hours for a typical kitchen extract system, and the area is cleaned down before we leave. Evenings, weekends or a closed day all work for a site in a place like Charvil.
- First we book a time that will not disrupt cooking.
- The system is checked from canopy to discharge.
- Grease readings are taken at set points using WFTT or DTT.
- We photograph the test points and record any sections we cannot reach.
- You get a report with readings, pictures and recommendations.
Getting ready for the visit
- Have your last certificate or report to hand
- Allow time for equipment near the work to be turned off and cool down
- Arrange a key holder or contact on site

Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Part by part
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Readings show if the cleans are frequent enough.
Horizontal duct runs
Grease settles on the floor of horizontal ducts as the air cools. Readings are taken along each run through its access panels.
Leave it or put it right?
A check after cleaning shows whether the work reached every part it should have, before the next clean is due. In a smaller place like Charvil, a site that has to close is felt quickly.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

Charvil questions
Do you work in villages like Charvil?
Yes, we work in villages as well as towns, and Charvil is covered. Photos of the system and directions to the site help us plan the visit.
Who carries out food hygiene inspections in Charvil?
Food hygiene inspections in Charvil are carried out by Wokingham council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
What is post-clean verification?
We visit after a clean, take readings at set points and photograph the system. The report flags anything missed.
How long does a TR19 inspection take?
It takes an hour or two for a single kitchen, longer for a large or complex system. The visit is timed so cooking isn’t disrupted.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Can the work be done while we’re closed?
Yes. Tell us your opening hours when you ask for a quote and we’ll book around them.
How much does TR19 inspection cost in Charvil?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.
Is a quote from pictures possible?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote typically follows within one working day. Some sites still need a visit, and we will say so.
TR19 inspection around Charvil
Look up Charvil on the FSA’s food hygiene register and you will find about 16 restaurants, cafés and canteens and about 5 takeaways within 1.5 miles or so of the middle of Charvil. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Environmental health officers from Wokingham council inspect food businesses in Charvil. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. Charvil is covered by Royal Berkshire 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.
Volunteers running a hall kitchen near St Patrick's Church, or anywhere in Charvil, may not know when the extract was last cleaned, and a grease test settles it. Commuter trade near Twyford station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
