TR19 inspection for kitchens and businesses in Rolvenden
Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). From the numbers, you can see whether cleaning is due. The work covers access surveys, wet film thickness tests and deposit thickness tests, and common reasons people get in touch are post-clean verification after another contractor’s clean and insurance renewals needing proof of TR19 cleaning.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
The paperwork matters as much as the work. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Keep to the recommended interval
- Send TR19 audit reports to your insurer on request
- Keep access panels clear and unpainted
- Store grease readings where your insurer can see them
Where sections couldn’t be reached, the report says where access panels would help. With panels fitted, the next clean can cover every section.
Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.
What TR19 inspection cannot fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Heavy deposits found on test, which still need cleaning
- Hidden runs that need access panels first
- Fire safety duties beyond the extract system
If you are not sure, just give us a ring on 0345 646 2711 or send us an email and we’ll give you a straight answer.

How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. On site, it takes an hour or two for a single kitchen, longer for a large or complex system. Visits to a village like Rolvenden are booked in advance, at a time that suits whoever runs the site.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- Grease readings are taken and pictures recorded.
- We report back with readings and a fixed quote.
Preparing for the visit
- Let us know about parking and loading
- Clear the space around the work
- Have your last certificate or report to hand

Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
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.
What affects the cost of TR19 inspection
We quote each job individually. This is what makes a difference:
- Site requirements such as sign-in and permits
- What state the system is in
- The number of sites or systems
- The size of the system
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.
What to send for a quote
When you contact us, these details help:
- The postcode and the type of business
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Close-ups of filters, grilles, hatches or access panels
The quickest way to a quote is to send pictures: 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.
What TR19 inspection looks like in Rolvenden
The FSA’s food hygiene register includes about 3 pubs and bars in Rolvenden and the streets around it, up to about 1.5 miles out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Rolvenden sits within the area of Kent Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from Ashford council inspect food businesses in Rolvenden. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Healthcare kitchens, like those at hospitals such as Benenden Hospital (about 2.4 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands. A hall kitchen that only cooks for events, whether near Parish Church of St Mary or elsewhere in Rolvenden, still needs its extract cleaned, just less often.

FAQs for Rolvenden
Do you work overnight in Rolvenden?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Rolvenden needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Do you cover smaller places like Rolvenden?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
How often should grease be tested?
Enough to be sure grease stays within the TR19® Grease figures between cleans. The readings themselves tell you if the interval needs to change.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
At what point does grease need cleaning?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. At the end, the area is cleaned down.
Do you carry out TR19 audits for insurers?
Yes. Insurers often want evidence the extract is managed to TR19®, and an audit report gives you that, with recommendations where something needs doing.
What happens on a pre-clean survey?
A survey finds out how the system is laid out, how dirty it is and what can be reached, before anyone starts cleaning. Missing access panels are noted ahead of the clean.
Signs you need TR19 inspection in Rolvenden
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. It isn’t legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and grease in the extract is part of that risk.
Signs it’s time to call us include:
- Ductwork where grease may be over the TR19 limits
- Kitchens taken over with no cleaning records
- An insurer’s request for a TR19 audit
- Sections of duct that cannot be reached
School kitchens, at schools like Rolvenden Primary School for example, are typically cleaned in the holidays so no lunches are lost.
