About our TR19 inspection in Charndon
A grease test measures how thick the grease is inside a kitchen extract system. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). The results show whether the system needs cleaning and how soon. If you have heavy grease suspected in the plenum or ducts and extracts that have never been grease tested, we can put it right.
In a small place like Charndon, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Good records are part of the job. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

TR19 inspection in Charndon: the local picture
In Charndon, food businesses are inspected by environmental health officers from Buckinghamshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Charndon is covered by Oxfordshire 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.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Claydon House is about 3 miles east), access may need planning. A hospital like Bicester Community Hospital, about 5.9 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Charndon is about 6 miles east of Bicester, in Oxfordshire. Every kind of commercial site in Charndon, we can take on TR19 inspection. We can work out of hours so the site keeps running. Our area takes in 443 places across Oxfordshire, large and small. There’s also a page for Oxford, roughly 14 miles from Charndon.
We cover every part of the OX27 postcode area for TR19 inspection and the streets around it. If you need TR19 inspection at premises on Main Street, Spencer Gardens and Wootton Green or anywhere close by, our technicians can take on the work.

Different parts, different methods
Schools, hospitals and care homes
Hospital and care home kitchens can cook all day, every day. Readings show if cleaning is frequent enough.
Canopy and plenum
Filters can look fine while the plenum behind them is heavily coated. That’s why we test behind them.
What we are called out for in Charndon
Some parts of a system are hard to reach, and grease can be missed there clean after clean. An inspection of a system in Charndon shows where access panels are missing, so panels can be fitted.
Common reasons sites call us include:
- Sites with gaps in their extract records
- Missing access panels found on survey
- Checking the result of a recent clean
- Ductwork where grease may be over the TR19 limits
If you run a church or community hall kitchen, near Church of St Michael or elsewhere in Charndon, its extract still collects grease from every lunch and event.
Before you book anyone
- Proof of accreditation you can verify
- Whether the quote shows VAT
- What’s included in the scope, part by part
- What paperwork you get at the end
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep access panels clear and unpainted
- Share inspection reports with your insurer or broker when asked
- Tell us if menus or opening hours change
- Never cook with filters missing
After post-clean verification, file the results with the cleaning certificate. The pair gives a clear record of the clean and the check.
Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.
What we do, step by step
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes an hour or two for a single kitchen, longer for a large or complex system. The timing of a visit to Charndon is set by you, and the travel is our side of the planning.
- We go through any past certificates and reports.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and photos recorded.
- We report back with readings and a fixed quote.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Make sure equipment near the work can be switched off and left to cool
- Mention any locked doors, roof access or ceiling voids
Get a fixed quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

Charndon: your questions answered
Who enforces fire safety at workplaces in Charndon?
Fire safety enforcement in Charndon is handled by Oxfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Is Charndon within the area you cover?
Yes. Charndon 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.
What does a pre-clean survey involve?
We look at the system from canopy to discharge, take grease readings and check access. It lets us plan the clean and give you a fixed quote.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
How long does a TR19 inspection take?
As a guide, it takes an hour or two for a single kitchen, longer for a large or complex system. The size of the system and the access make the difference.
Do we have to follow TR19 by law?
No, TR19® is not legislation. But the responsible person must assess and reduce fire risk under the Fire Safety Order 2005, and grease in the extract is part of that. Many insurance policies also require TR19 adherence.
Can you verify a clean after it’s been done?
It’s an inspection after cleaning, to show what state the system was left in, whoever did the clean.
Can you look after several sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Managing agents and facilities teams in Charndon
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Fixed quotes for TR19 inspection in Charndon
The diagnosis comes before the price. We look at:
- A single visit or a regular plan
- Working hours and out-of-hours timing
- The condition we find in the survey
- Parking and loading at the site
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
What we need to know
To speed up the quote, send us:
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your last certificate, test record or report
- Wide photos of the system and the area around it
To get a fixed quote, ring 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You will typically have a quote within one working day.
What happens if it’s left?
Catching heavy deposits early keeps the fix small. Left alone, grease keeps building between cleans. It’s worth booking a check, because nobody sees inside a duct day to day.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.
