Part by part
Vertical risers
Access to risers is often limited. The survey shows exactly what access there is.
Horizontal duct runs
Grease can gather thickly at bends and along long runs, well away from where anyone looks.
TR19 inspection in Ashbank, done properly
Before any clean in Ashbank, we survey the canopy, plenum, filters, ducts, fan and discharge. Access is checked along the full length, and record grease readings at set points. We are often asked to deal with pre-clean surveys before a first TR19 clean and missing access panels found on survey, across post-clean checks, deposit thickness tests and insurer audits.
Somewhere as small as Ashbank, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Landlords, agents and facilities managers
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Leave it or put it right?
Without readings, you are 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. Somewhere as small as Ashbank, losing a kitchen or building to a fault is felt by everyone who uses it.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.

Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Book the next test on the date in the report
- Report grease dripping from the canopy
- Flag changes in how much frying the kitchen does
- Keep TR19 certificates, readings and reports together
Keep the verification report next to the certificate it relates to. Together they show the system was cleaned and checked.
Keep all TR19 records together so you can produce them quickly.
When something else is needed
We will always give you a straight diagnosis, so here’s what TR19 inspection will not do:
- Ductwork that was designed or installed badly
- Hidden runs that need access panels first
- Mechanical faults in the extract
If you’re not sure, just call us on 0345 646 2711 or use the quote form and we’ll give you a straight answer.

Common questions in Ashbank
Do you work in villages like Ashbank?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can a school canteen extract in Ashbank be done out of term time?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Ashbank. Tell us your holiday dates and we will book the visit for when the site is empty.
What is a WFTT or DTT grease test?
Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. The results are given in microns.
What does TR19 mean?
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 expects a risk-based approach.
Do we have to follow TR19 by law?
No. TR19® is not law; it’s BESA’s specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, which requires the responsible person to reduce fire risk, and TR19® is what insurers and fire officers look to.
What does TR19 inspection cost?
Every site is different, so each gets its own fixed quote. For a quote, call 0345 646 2711 or email us with the site type, opening hours and a few photos.
Will you produce a report for our insurer?
Yes. Our TR19 audits cover readings, photos, access and a recommended cleaning interval. You can pass it straight to your insurer or broker.
Is a quote from pictures possible?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
TR19 inspection around Ashbank
Food Standards Agency records list about 9 restaurants, cafés and works canteens in and around Ashbank, up to about a mile and a half out. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Ashbank sits within the area of Kent Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Kitchens in Ashbank get their food hygiene inspections from Maidstone council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
Historic houses near Ashbank, such as Leeds Castle about 0.6 miles east, are a reminder that older buildings with event kitchens can have long, awkward duct routes. A hall kitchen that only cooks for events, whether near St Nicholas's Church or elsewhere in Ashbank, still needs its extract cleaned, just less often.

Common problems we fix in Ashbank
Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Measuring it is the first step to keeping it under control.
What we’re most often called out for:
- Checking the result of a recent clean
- Surveys needed before quoting a full clean
- Heavy grease suspected in the plenum or ducts
- Missing TR19 certificates or history
Bursars and site managers at schools such as Leeds and Broomfield Church of England Primary School tend to book extract cleaning for when the kitchen is empty.
Before you book anyone
- Whether a written report and photos are included
- Whether they recommend a next date
- Whether the whole system is included, or only the parts that are easy to reach
- Whether inaccessible sections are listed on the report
What we do, step by step
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes around an hour or two per canopy and duct system. We agree a date with you, plan the drive to Ashbank and turn up when the site is quiet.
- The visit is arranged for when the kitchen is not busy.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease readings are taken at set points using WFTT or DTT.
- We photograph the test points and record any sections we cannot reach.
- The findings go into a report with readings, photos and a recommended next clean.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
