TR19 inspection in Cores End, 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. Those are minimums, and grease readings help set the real interval. Common call-outs are for cleaning intervals that may not suit the kitchen and extracts that may be over the 200 micron mean, on post-clean checks, wet film thickness tests and access surveys.
For a kitchen in or near Cores End, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
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.

Signs you need TR19 inspection in Cores End
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. It is not 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.
Keep an eye out for any of the following:
- Kitchens taken over with no cleaning records
- Pre-clean surveys before a first TR19 clean
- Insurers asking for TR19 evidence
- Uncertainty over how often to clean
If you cook for passing trade around Bourne End station, the extract can be cleaned between your last and first customer.
Questions to ask before booking
- What insurance they carry
- What paperwork you get at the end
- Which accreditations they hold, and whether you can check them
- What hours they’ll be on site
Why it’s worth doing now in Cores End
Surveying first means the clean goes to plan. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, and the quote reflects the real job. Planning a trip to Cores End ahead is easier for everyone than a rushed one.
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.

For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes a morning or less for one kitchen, more where there are several systems. We agree a date with you, plan the drive to Cores End and turn up when the site is quiet.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and photos recorded.
- We report back with readings and a fixed quote.
Getting ready for the visit
- Let us know about parking and loading
- 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

Advice
Questions from Cores End
Do you cover smaller places like Cores End?
Yes. Cores End is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Can school kitchens in Cores End be cleaned in the holidays?
Yes, holiday work suits schools best. With about 7 schools and colleges on the FSA’s register within roughly a mile and a half of Cores End, it pays to plan holiday dates ahead. Send us your term dates when you phone us on 0345 646 2711 or send us an email, and we will fit the work in.
What accreditations do you have?
We’re 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.
Is a quote from pictures possible?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
How do you measure grease in a kitchen extract?
We measure the grease at set points with a WFTT or DTT test, and set against the TR19® Grease figures.
What do you need from me for a quote?
Some photos and a quick description of the system plus the address and your hours. We will ask for anything else we need.
What is post-clean verification?
Post-clean verification is a check after a clean, with fresh grease readings and pictures. It can follow our own cleans or another contractor’s.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.

When it’s something else
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Sections with no access, until panels are fitted
- The responsible person’s own fire risk assessment
- Mechanical faults in the extract
If you are not sure, just call 0345 646 2711 or drop us a line and we’ll give you a straight answer before booking.
