About our TR19 inspection in Mill Street
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Testing is how you know where your system stands. The work covers post-clean checks, pre-clean surveys and access surveys, and the jobs we see most are missing TR19 certificates or history and post-clean verification after another contractor’s clean.
In a small place like Mill Street, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
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 carry full insurance.

In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
When to call us in Mill Street
Grease in a duct is flammable fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Measuring it is the first step to keeping it under control.
Common reasons sites call us are:
- Ductwork where grease may be over the TR19 limits
- Missing access panels found on survey
- Systems cleaned on a calendar with no measurements
- Insurers asking for TR19 evidence
Where a hall near Church of St Mary, or anywhere in Mill Street, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Before booking anyone
- Whether the quote is based on a survey or photos
- If the quote is a fixed price or an estimate
- Whether the work can be done while the site is closed
- Whether VAT is included
The process
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 a morning or less for one kitchen, more where there are several systems. Somewhere as small as Mill Street, the date and timings are agreed with you well before the day.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
How to prepare
- Arrange a key holder or contact on site
- Tell us where we can park and unload
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Our report lists what was cleaned and when, which is useful to have ready. Mill Street is about 55 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible.

Your questions about TR19 inspection in Mill Street
Do you work in villages like Mill Street?
Yes. Mill Street 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.
Who enforces fire safety at workplaces in Mill Street?
Fire safety enforcement in Mill Street is handled by Essex County Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you price the work without visiting?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
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.
Can the work be done while we are closed?
Yes. Evenings, nights and weekends are normal working hours for us, so you don’t have to close during trading.
What should I send you?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply give us a ring on 0345 646 2711 or use the quote form.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
At what point does grease need cleaning?
TR19® Grease says grease should not go over a mean of 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
For landlords and multi-site operators
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Why it’s worth doing now in Mill Street
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. It’s worth booking a check, because nobody sees inside a duct day to day.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.
Why Mill Street businesses choose us
- One contact for all your sites in London and the South East
- Fixed quotes, normally within one working day
- We are fully insured
- CHAS and SafeContractor accredited, with ISO 9001

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Flag oily drips near the extract
- Keep the route to access panels clear
- Clean or swap grease filters as often as the kitchen needs
- File every inspection report with your certificates
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can quote to do it.
When cooking hours or the menu change, check the interval still fits. Fresh readings show whether it needs to change.
