How we handle TR19 inspection in Stalisfield
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. The results show whether the system needs cleaning and how soon. Typical jobs include systems cleaned on a calendar with no measurements and systems that need surveying before cleaning, on post-clean checks, wet film thickness tests and deposit thickness tests.
For a kitchen in or near Stalisfield, the visit is planned around opening hours and the journey, 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.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What TR19 inspection looks like in Stalisfield
It’s Swale council that sends environmental health officers to food businesses in Stalisfield. 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. At about 43 miles from central London, Stalisfield sits well inside the area we cover. Evening, overnight and weekend visits are all possible.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Belmont House and Gardens is about 2.6 miles north-east), access may need planning.

Questions from Stalisfield
Do you work overnight in Stalisfield?
Yes, we can come after you close and finish before you open. It means the site in Stalisfield keeps running as normal. Your opening times are the first thing we ask for.
Is Stalisfield within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Stalisfield included. The journey is planned ahead, so a few details about the route help.
Why survey before a clean?
We check the layout, the grease levels and the access, before anyone starts cleaning. Any access problems are flagged ahead of the clean.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
What happens to the waste?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Call us any time and explain what’s happened.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
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. Where responsibility is shared, records matter even more.
When something else is needed
Some problems need a different service or another trade:
- A faulty or failing extract fan
- The grease itself, which needs a full or spot clean
- Design faults in the extract system
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we’ll tell you honestly before you book.

Common problems we fix in Stalisfield
Looking at a canopy tells you little about what’s in the duct. A system can look clean at the filters and be heavily coated further in, so readings are the reliable guide.
These are the problems we see most often:
- Cleaning intervals that may not suit the kitchen
- Systems cleaned on a calendar with no measurements
- Insurers asking for TR19 evidence
- Confirming a clean reached the whole system
Where a hall near Church of St Mary, or anywhere in Stalisfield, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Before booking anyone
- What hours they’ll be on site
- Whether the quote shows VAT
- What happens if part of the system can’t be accessed
- Whether the quote is based on a survey or pictures
How we price TR19 inspection
The survey tells us what the work involves. The main factors are:
- How big the system is
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
Kitchens, offices, schools and hospitals are all priced 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 explain each part.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Close-ups of filters, grilles, hatches or access panels
- Your last certificate, test record or report
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Different parts, different methods
Horizontal duct runs
Flat duct runs collect grease along their base. Readings are taken along each run through its access panels.
Vertical risers
Risers can be hard to get into. The survey shows exactly what access there is.
Leave it or put it right?
Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Left alone, grease keeps building between cleans. In a small place like Stalisfield, a system that fails can take a site out of use.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.
