TR19 Inspection in Shillington
TR19 inspection across Shillington and nearby, timed so the site keeps working and signed off in writing with photos.

How we handle TR19 inspection in Shillington
A pre-clean survey is the diagnosis, and the clean is the treatment. We look at the system, take grease readings and photograph what we find, so the clean can be planned properly. Typical jobs include checking the result of a recent clean and sections of duct that can’t be reached, across post-clean checks, wet film thickness tests and pre-clean surveys.
In a small place like Shillington, 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, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Your questions about TR19 inspection in Shillington
Can you work in Shillington outside opening hours?
Yes, nights and weekends are routine for us. That way a site in Shillington doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
Will you come out to Shillington?
Yes, Shillington is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
What does a pre-clean survey involve?
A survey finds out how the system is laid out, how dirty it is and what can be reached, so the clean goes to plan. Any access problems are flagged ahead of the clean.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Is TR19 a legal requirement?
No. It’s the benchmark rather than the law. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so following it is the sensible course.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
What happens to the waste?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Multi-site and managed buildings
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Facilities teams in offices, schools and healthcare sites book us too across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.

Looking after it afterwards
To keep the system working properly between visits:
- Keep canopy edges and gutters wiped down
- Keep grease filters clean and fitted properly
- Keep TR19 certificates, readings and reports together
- Keep the route to access panels clear
After the inspection, we send a report showing each reading, its location and photos. File it alongside your TR19 certificates.
Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.
What we do, step by step
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 any work starts, 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. Pictures of the system and its access let us plan the work in Shillington before we set off.
- The visit is arranged for when the kitchen is not busy.
- Every part of the system is examined, end to end.
- Grease readings are taken at set points using WFTT or DTT.
- We photograph the test points and record any sections we can’t reach.
- We send a report setting out the readings, pictures and next steps.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Mention any parking or loading restrictions
- Find the previous report, if there is one
Getting a quote
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, and then give you a fixed quote. To start, ring 0345 646 2711 or send us an email.

Signs you need TR19 inspection in Shillington
Kitchens change: a new menu, longer hours or more frying can all add grease. The old cleaning schedule may not match the kitchen any more.
If you notice any of these, it’s worth a diagnosis:
- Kitchens whose menu or hours have changed
- Missing TR19 certificates or history
- Missing access panels found on survey
- Extracts that may be over the 200 micron mean
Volunteers running a hall kitchen near Church of All Saints, or anywhere in Shillington, may not know when the extract was last cleaned, and a grease test settles it.
Before you book anyone
- Whether VAT is included
- Whether inaccessible sections are listed on the report
- What’s included in the scope, part by part
- Whether they’re fully insured
How we price TR19 inspection
A fixed price needs a few facts first. We look at:
- What state the system is in
- One-off work versus a regular cycle
- Whether we need access equipment or extra panels
- How many systems or sites are involved
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before work begins.
What we need to know
When you call or email, these details help:
- Detail shots of panels, filters and grilles
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- Problems your staff have spotted
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
What TR19 inspection can’t fix
Not every problem is solved by TR19 inspection, and we’d rather say so up front. It does not solve:
- Fire safety duties beyond the extract system
- Ductwork that was designed or installed badly
- Mechanical faults in the extract
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we’ll tell you honestly before booking.
