What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
About our TR19 inspection in Forty Green
Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). From the numbers, you can see whether cleaning is due. The work covers access surveys, post-clean checks and deposit thickness tests, and common reasons people get in touch are an insurer’s request for a TR19 audit and systems cleaned on a calendar with no measurements.
Work in a small place like Forty Green starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

The process
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes around an hour or two per canopy and duct system. A quick note on how to find the site and where to park makes a visit to Forty Green run smoothly.
- 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.
- The findings go into a report with readings, pictures and a recommended next clean.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear loose items from the work area

Getting a quote

Who inspects food businesses in Forty Green?
In Forty Green, it’s Buckinghamshire council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can a school canteen extract in Forty Green be done out of term time?

It takes around an hour or two per canopy and duct system. The visit is timed so cooking isn’t disrupted.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.

Forty Green kitchens: local notes
There are about 24 cafés, restaurants and staff canteens and about 4 sandwich bars and takeaways in Forty Green and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. For any of them with a canopy, measuring grease is better than guessing when to clean. Forty Green sits within the area of Buckinghamshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. In Forty Green, food businesses are inspected by environmental health officers from Buckinghamshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Church and community hall kitchens, near Church of St Michael and All Angels or anywhere around Forty Green, are easy to forget, but their extracts collect grease like any other. School kitchens, at schools like Holtspur School & Pre-School for example, are normally cleaned in the holidays so no lunches are lost. Commuter trade near Beaconsfield station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

What else we do in Forty Green
Part by part
Extract fan and discharge
A greasy fan works harder and wears faster. The inspection shows whether it needs cleaning now.
Schools, hospitals and care homes
We fit testing around service times and school holidays to avoid disruption.
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Keep grease filters clean and fitted properly
- File every inspection report with your certificates
- Don’t box in or cover duct access panels
- Have the latest report ready for insurance renewals
You get a report with the grease readings, where they were taken and pictures of each point. File it alongside your TR19 certificates.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.
Why deal with it now?
Post-clean verification shows whether the system was left the way the certificate says, before the next clean is due. A fault that closes a site in a village like Forty Green affects everyone who depends on it.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before we start.
