TR19 inspection in Flaunden, done properly
A grease test measures how thick the grease is inside a kitchen extract system. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. From the numbers, you can see whether cleaning is due. The work covers deposit thickness tests, post-clean checks and wet film thickness tests, and people most often call us about uncertainty over how often to clean and systems cleaned on a calendar with no measurements.
In a village or hamlet like Flaunden, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Do you need TR19 inspection in Flaunden?
Grease is fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Knowing how much there is lets you act before it becomes a hazard.
Keep an eye out for any of the following:
- Missing TR19 certificates or history
- Surveys needed before quoting a full clean
- Ductwork where grease may be over the TR19 limits
- Missing access panels found on survey
Church and community hall kitchens, near Church of St Mary Magdalene (Church of England) or anywhere around Flaunden, are easy to forget, but their extracts collect grease like any other.
Before you book anyone
- If they look at the system before pricing
- Exactly which parts of the system are covered
- Whether the quote shows VAT
- Whether a written report and pictures are included
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Clean grease off the canopy between professional cleans
- Keep grease filters clean and fitted properly
- Have the latest report ready for insurance renewals
- Keep access panels clear and unpainted
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can quote to do it.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.
What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Honest limits
We won’t sell you work that does not address the problem, so these are the things it won’t cover:
- Mechanical faults in the extract
- Ductwork that was designed or installed badly
- The legal duty, which stays with the responsible person
If in doubt, call us on 0345 646 2711 or use the quote form and we’ll say what we think before booking.

Flaunden kitchens: local notes
Look up Flaunden on the FSA’s food hygiene register and you will find about 3 restaurants, cafés and canteens within roughly a mile and a half of the centre of Flaunden. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. It’s Dacorum council that sends environmental health officers to food businesses in Flaunden. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Flaunden sits within the area of Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Bursars and site managers at schools such as St Clement Danes School tend to book extract cleaning for when the kitchen is empty. If your kitchen is in a listed or historic building, like the houses around Flaunden (Chenies Manor House is about 1.6 miles south), fitting access panels needs care.

What affects the cost of TR19 inspection
The diagnosis comes before the price. The main factors are:
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
- The scale of the work
- Access, including roofs, risers and ceiling voids
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before any work starts.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
Getting a quote does not take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Common questions in Flaunden
Which fire and rescue service is responsible for Flaunden?
That is Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Which environmental health team covers Flaunden?
The local authority for Flaunden is Dacorum council, and its environmental health team does the inspecting. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
What is post-clean verification?
Verification means repeat readings and pictures once the clean is done. The report flags anything missed.
Can you quote from pictures?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
How much does TR19 inspection cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before any work starts.
What if parts of the system can’t be reached?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
What we do, step by step
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the TR19 inspection, clear away and hand over the paperwork. The visit itself takes a couple of hours for a typical kitchen extract system. Rural roads and tight entrances are worth telling us about before a visit to Flaunden.
- 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.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before we start.

What the work involves, part by part
Canopy and plenum
We look over the canopy, inside and out, with readings where grease collects.
Extract fan and discharge
We look at where the extract discharges outside, since grease reaches the very end of the system.
