TR19 inspection for kitchens and businesses in Wendover Dean
A pre-clean survey is the diagnosis, and the clean is the treatment. We look at the system, take grease readings and photograph what we find, so the quote and the clean fit the real system. The work covers wet film thickness tests, pre-clean surveys and post-clean checks, and common reasons people get in touch are missing access panels found on survey and extracts that may be over the 200 micron mean.
Somewhere as small as Wendover Dean, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

For landlords and multi-site operators
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
How it works
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. After that, the work takes an hour or two for a single kitchen, longer for a large or complex system. Photos of the system and how to reach it help us plan a visit to Wendover Dean.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- We report the findings and flag any areas that need more work.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Clear the space around the work
- Tell us the best time to work, such as after service or at a weekend
Ask for a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
Advice
Different parts, different methods
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Readings show if the cleans are frequent enough.
Extract fan and discharge
A greasy fan works harder and wears faster. Readings show if it needs attention before the next clean.
TR19 inspection in Wendover Dean: the local picture

Buckinghamshire Fire and Rescue Service covers Wendover Dean. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you look after a school kitchen, at a school such as John Colet School or anywhere near Wendover Dean, the holidays are the usual time for a TR19® clean. If your kitchen is in a listed or historic building, like the houses around Wendover Dean (Cholesbury Manor House is about 3.5 miles north-east), fitting access panels needs care. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Chiltern Hospital is the nearest hospital to Wendover Dean, about 3.4 miles south-east.

Why it’s worth doing now in Wendover Dean
Skipping grease testing leaves the cleaning interval to guesswork. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, which you won’t know without measuring. It’s worth booking a check, because nobody sees inside a duct day to day.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.

Wendover Dean: your questions answered
Who is the fire and rescue service for Wendover Dean?
It’s Buckinghamshire Fire and Rescue Service, which covers Wendover Dean. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Which council inspects kitchens in Wendover Dean?
The local authority for Wendover Dean is Buckinghamshire council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
What is a WFTT or DTT grease test?
The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. Readings are taken at set points through the system.
Do you survey before quoting?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
How long does grease testing take?
An inspection takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Sites with several canopies take longer, so call us on 0345 646 2711, or send details by email and we’ll plan it.
How far ahead should we book?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
How we price TR19 inspection
Sites vary more than people expect. The main factors:
- Whether it’s a one-off visit or part of a schedule
- The times the site is available
- How many systems or sites are involved
- Access, including roofs, risers and ceiling voids
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
What to send for a quote
You do not need the technical terms. Just send:
- A few general shots of the system
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Where the site is and what kind of site it is
- Problems your staff have spotted
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
