Common problems we fix in Green Street Green
TR19® is the benchmark that insurers, fire officers and EHOs refer to. 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.
Look out for these warning signs:
- Post-clean verification after another contractor’s clean
- Pre-clean surveys before a first TR19 clean
- An insurer’s request for a TR19 audit
- Ductwork where grease may be over the TR19 limits
If you look after a school kitchen, at a school such as Greenlands Primary School or anywhere near Green Street Green, the holidays are the usual time for a TR19® clean.

TR19 inspection in Green Street Green
Before any clean in Green Street Green, we survey the canopy, plenum, filters, ducts, fan and discharge. We check where the access panels are and whether every section can be reached, and grease readings are taken at set points. If you’re dealing with confirming a clean reached the whole system and extracts that have never been grease tested, we can put it right, from access surveys, wet film thickness tests and insurer audits onwards.
Work in a small place like Green Street Green starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
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.

How long does a TR19 inspection take?

Is a quote from photos possible?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and we normally come back within one working day. Some sites still need a visit, and we’ll say so.

Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, and set against the TR19® Grease figures.
What does TR19 mean?

What affects the quote in Green Street Green
Some jobs are bigger than they look, and some smaller. The main factors:
- How easy every part is to reach
- Whether several sites go on one quote
- Working hours and out-of-hours timing
- The condition we find in the survey
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
Asking for a quote
When you contact us, it’s useful to have:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
We do not publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, ring 0345 646 2711 or send us an email.

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
What happens if it’s left?
Post-clean verification shows whether the system was left the way the certificate says, before the next clean is due. Rural sites cannot always move to another kitchen or room when something fails.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
