TR19 inspection for kitchens and businesses in Tring
After a clean, post-clean verification checks the result, with new readings and pictures of the cleaned areas. It shows whether the system was left in the condition the paperwork describes. If you are dealing with an insurer’s request for a TR19 audit and missing access panels found on survey, we can help.
In a smaller place like Tring, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Kitchen extracts in Tring
There are about 18 restaurants, cafés and works canteens and about 12 takeaways and sandwich shops within about 1.5 miles of central Tring, according to the Food Standards Agency’s register. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Fire safety in Tring falls to Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Food hygiene inspections in Tring are the job of Dacorum council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you run catering at a healthcare site, such as a hospital like Stoke Mandeville Hospital about 5.9 miles west, the extract may need cleaning more often than a part-time kitchen. If you look after a school kitchen, at a school such as Bishop Wood Church of England Junior School or anywhere near Tring, the holidays are the usual time for a TR19® clean.

What the work involves, part by part

The extract fan and its housing collect grease too. They’re included in the readings and photos.
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so we arrange access ahead of time.
Questions from Tring
Can school kitchens in Tring be cleaned in the holidays?
Yes, holiday work suits schools best. Around Tring, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Just phone us on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Which fire and rescue service is responsible for Tring?
Fire safety enforcement in Tring is handled by Hertfordshire Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
At what point does grease need cleaning?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, with 500 microns or more anywhere needing immediate spot cleaning.
Is TR19 cleaning the law?
No. TR19® is a specification, not a statute. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so following it is the sensible course.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What do you need from me for a quote?
A short description and a few pictures, with the address and opening hours. We will ask for anything else we need.
What does a pre-clean survey involve?
We look at the system from canopy to discharge, take grease readings and check access. From it, we plan the clean and quote a fixed price.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Aftercare tips
Simple habits between visits make a real difference. We recommend:
- Flag oily drips near the extract
- Have the latest report ready for insurance renewals
- Clean or swap grease filters as often as the kitchen needs
- File every inspection report with your certificates
For an insurer audit, send them the report as it is, with readings, photos and any areas not accessible.
Test grease regularly instead of relying on the calendar. It shows if build-up is speeding up.
When something else is needed
In fairness, some problems need a different fix:
- A faulty or failing extract fan
- The grease itself, which needs a full or spot clean
- Parts of the duct nobody can reach yet
Not sure which it is? You can phone us on 0345 646 2711 or email us and we’ll tell you honestly before you book.

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
What happens on the day
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. On site, it takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Evenings, weekends or a closed day all work for a site in a place like Tring.
- 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.
- We report the findings and flag any areas that need more work.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Name a contact who can let us in at the agreed time
- Make sure equipment near the work can be switched off and left to cool
Get a fixed quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.

Signs you need TR19 inspection in Tring
Grease is 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. Knowing how much there is lets you act before it becomes a hazard.
Keep an eye out for these warning signs:
- Confirming a clean reached the whole system
- Extracts that have never been grease tested
- Cleaning intervals that may not suit the kitchen
- Systems that need surveying before cleaning
If your kitchen is in a listed or historic building, like the houses around Tring (Cholesbury Manor House is about 2.9 miles south), fitting access panels needs care.
