TR19 inspection in Bledlow Ridge, done properly
BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Grease testing shows whether your kitchen needs cleaning more often than that. The work covers access surveys, pre-clean surveys and insurer audits, and the jobs we see most are extracts that may be over the 200 micron mean and missing TR19 certificates or history.
In a small place like Bledlow Ridge, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Report grease dripping from the canopy
- Keep to the recommended interval
- Store grease readings where your insurer can see them
- Share inspection reports with your insurer or broker when asked
Where sections couldn’t be reached, the report says where access panels would help. Fitting them before the next clean means the whole system gets done.
Test grease regularly instead of relying on the calendar. It spots changes in how fast grease builds.
Part by part
Canopy and plenum
We look over the canopy, inside and out, and note where grease has gathered.
Extract fan and discharge
Grease on the fan adds to wear. The inspection shows whether it needs cleaning now.
How the visit works
Night work is normal for us. 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 an hour or two for a single kitchen, longer for a large or complex system. Somewhere like Bledlow Ridge, lanes, gates and parking are worth mentioning in advance.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- Grease readings are taken at set points using WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- We send a report setting out the readings, pictures and next steps.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Clear the space around the work
- Arrange a key holder or contact on site

Signs you need TR19 inspection in Bledlow Ridge
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and in a kitchen that means keeping grease under control.
Clients normally contact us when they notice one of these:
- Systems cleaned on a calendar with no measurements
- Cleaning intervals that may not suit the kitchen
- Missing TR19 certificates or history
- Sections of duct that cannot be reached
If you run catering at a historic house or estate in the area (West Wycombe Park House is about 2.9 miles south-east), event kitchens in older buildings often have awkward duct runs that need planning.
