TR19 inspection for kitchens and businesses in Hextable
Think of a TR19 inspection as the diagnosis before the treatment. Readings, pictures and notes on access are gathered from end to end, so the clean can be planned properly. The work covers post-clean checks, pre-clean surveys and deposit thickness tests, and the jobs we see most are systems that need surveying before cleaning and missing TR19 certificates or history.
Around a smaller place like Hextable, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
What TR19 inspection cannot fix
Some problems need a different service or another trade:
- Hidden runs that need access panels first
- Fire safety duties beyond the extract system
- Mechanical faults in the extract
If in doubt, call 0345 646 2711 or drop us a line and we will say what we think.
What we work on in Hextable
- Access surveys
- Wet film thickness tests
- Deposit thickness tests
- Pre-clean surveys
- Post-clean checks
- Insurer audits
Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Clean or swap grease filters as often as the kitchen needs
- Send TR19 audit reports to your insurer on request
- Do not box in or cover duct access panels
- Flag changes in how much frying the kitchen does
The report recommends when the system should next be cleaned and tested, from the measured grease and the kitchen’s hours.
Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.
What happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes an hour or two for a single kitchen, longer for a large or complex system, and the area is cleaned down before we leave. Tell us about any gates, ladders or locked plant areas at your site near Hextable when you book.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- We report the findings and flag any areas that need more work.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
- Move anything stored near the system
Getting a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or email us.
Advice
Fixed quotes for TR19 inspection in Hextable
Before we fix a price, we need to know a few things. We check:
- Site rules, permits and inductions
- What state the system is in
- Working hours and out-of-hours timing
- How big the system is
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.
What to send for a quote
When you contact us, it’s useful to have:
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
- When the site is open and when it’s quiet
The quickest way to a quote is to send photos: 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.
What happens if it’s left?
Without readings, you’re guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. It’s better to plan the work at a site near Hextable than wait for a failure.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Why us?
- Full insurance on every job
- One contact for all your sites in London and the South East
- Accredited under CHAS and SafeContractor, with ISO 9001
- A written report with pictures after each visit

Common questions in Hextable
Which fire authority looks after Hextable?
Hextable is in the area of Kent Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you get to a site in Hextable?
Yes, we work in villages as well as towns, and Hextable is covered. Let us know about access, parking and anything unusual about getting there when you book.
How often should a kitchen extract be inspected?
It depends on how heavily the kitchen cooks. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and grease readings help set the real interval.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What is grease thickness testing?
Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, and set against the TR19® Grease figures.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
TR19 inspection in Hextable: the local picture
The FSA’s data shows about 8 pubs, bars and clubs registered within 1.5 miles or so of the middle of Hextable. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Hextable get their food hygiene inspections from Sevenoaks council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Hextable falls to Kent 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.
Historic houses near Hextable, such as Hall Place and Gardens about 2.7 miles north, are a reminder that older buildings with event kitchens can have long, awkward duct routes. Church and community hall kitchens, near St Peter or anywhere around Hextable, are easy to forget, but their extracts collect grease like any other. If you run catering at a healthcare site, such as a hospital like West Hill Hospital about 2.6 miles north-east, the extract may need cleaning more often than a part-time kitchen.
