TR19 inspection for kitchens and businesses in Deal
BESA sets minimum cleaning intervals by daily use: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Grease testing shows whether your kitchen needs cleaning more often than that. The work covers access surveys, insurer audits and deposit thickness tests, and the jobs we see most are post-clean verification after another contractor’s clean and systems that need surveying before cleaning.
Kitchens in towns like Deal are often in older buildings that were never designed for them, which can mean awkward duct routes, long flat runs and not enough access panels. Where the duct cannot be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Your questions about TR19 inspection in Deal
Is TR19 inspection any different in a coastal place like Deal?
It can. Deal is within about 1 mile of the coast, and salt air speeds up corrosion. Corroded fixings and housings are noted on the report so they can be dealt with.
Which council inspects kitchens in Deal?
In Deal, it’s Dover council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then give us a ring on 0345 646 2711 or use the quote form.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
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 carry full insurance.
What do the grease readings need to be?
The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. We show your readings against those figures.
What happens if you can’t reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
When something else is needed
In fairness, there are a few things this work won’t fix:
- Installation problems, which fall under design guidance such as DW172
- Removing the grease, which is a separate clean
- A faulty or failing extract fan
If in doubt, ring 0345 646 2711 or email us and we’ll say what we think.
What the work covers
- Pre-clean surveys
- Access surveys
- Post-clean checks
- Wet film thickness tests
- Insurer audits
- Deposit thickness tests
Keeping the system healthy
Results last longer with the right care. We suggest:
- Store grease readings where your insurer can see them
- Flag oily drips near the extract
- Book the next test on the date in the report
- Keep canopy edges and gutters wiped down
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can arrange it.
Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.
Multi-site and managed buildings
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Deal kitchens: local notes
The coast is only about 1 mile from Deal. Salt air speeds up corrosion of roof-level fans, discharge cowls and their fixings. The FSA’s food hygiene register includes about 34 bars, pubs and nightclubs and about 5 hotels and guest houses within 1.5 miles or so of the middle of Deal. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Kent Fire and Rescue Service covers Deal. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you look after a school kitchen, at a school such as Castle Community College or anywhere near Deal, the holidays are the usual time for a TR19® clean. Church and community hall kitchens, near St Saviour's or anywhere around Deal, are easy to forget, but their extracts collect grease like any other.
Deal is about 14 miles east of Canterbury, in Kent. Every kind of commercial site in Deal, TR19 inspection is something we can help with.

What’s near Deal
Typical jobs here are in premises near Betteshanger Park, Brickmakers Arms and Deal Parochial Church of England Primary School and the streets around them. The closest station to Deal is Deal station, roughly 0.5 miles north-east. Nearby you’ll also find Kent Museum of the Moving Image (0.6 miles north-east) and Deal Castle (0.5 miles east).
How it works
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes around an hour or two per canopy and duct system. Three things shape a visit in Deal: when you’re closed, where we can park and how we get to the system.
- We go through any past certificates and reports.
- The layout is traced from the canopy to the discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
How to prepare
- Agree a time when the area can be out of use
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us about site rules, permits or sign-in
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
Advice
Common problems we fix in Deal
Kitchens change: a new menu, longer hours or more frying can all add grease. The old cleaning schedule may not match the kitchen any more.
Look out for any of the following:
- Extracts that have never been grease tested
- Cleaning intervals that may not suit the kitchen
- Parts of the system left out of past cleans
- Pre-clean surveys before a first TR19 clean
If you run catering at a historic house or estate in the area (Walmer Castle is about 1.2 miles south), event kitchens in older buildings often have awkward duct runs that need planning.
What to look for in a quote
- Whether the whole system is included, or only the parts that are easy to reach
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

What the work involves, part by part
Horizontal duct runs
Bends and long runs can hold heavy deposits, well away from where anyone looks.
Extract fan and discharge
The discharge at the end of the system is checked as well, since grease reaches the very end of the system.
