How we handle TR19 inspection in Great Amwell
After a clean, post-clean verification checks the result, with fresh grease readings, photos and a look at the areas that were cleaned. It shows whether the system was left in the condition the paperwork describes. If you have kitchen extract systems with no recent grease readings and cleaning intervals that may not suit the kitchen, we can help.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
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.

Questions from Great Amwell
Can you come to Great Amwell after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you give us a ring on 0345 646 2711 or send us an email, mention when the site is quiet.
Which fire authority looks after Great Amwell?
That is Hertfordshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you check other contractors’ cleans?
Verification means repeat readings and photos once the clean is done. Any areas that weren’t cleaned properly are flagged.
What does TR19 inspection cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, typically ready within one working day.
What should I send you?
A short description and a few photos, with the address and opening hours. If we need more, we’ll ask.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
How long does grease testing take?
Typically, the inspection takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. The size of the system and the access make the difference.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we will quote them together.
Between visits
Think of this as the after-treatment advice, short and simple:
- Keep grease filters clean and fitted properly
- Look out for grease drips round the canopy edge
- Flag changes in how much frying the kitchen does
- Keep to the recommended interval
After the inspection, we send a report showing each reading, its location and pictures. Keep it with your fire safety and TR19 records.
Keep all TR19 records together so you can produce them quickly.
What happens on the day
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes an hour or two for a single kitchen, longer for a large or complex system. Seeing the system in pictures first means the trip to Great Amwell can be planned properly.
- First we look at the system’s cleaning history, if there is one.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Move anything stored near the system
- Let us know about permits to work or site inductions
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711 or drop us a line.
Related advice
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
When something else is needed
A few issues sit outside what this work can do:
- Ductwork that was designed or installed badly
- The legal duty, which stays with the responsible person
- Hidden runs that need access panels first
If in doubt, give us a ring on 0345 646 2711, or email photos and we’ll say what we think.

Fixed quotes for TR19 inspection in Great Amwell
The diagnosis comes before the price. The main factors are:
- The condition of the system
- Any permits to work or inductions
- Parking and loading at the site
- The number of sites or systems
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and the price is agreed before any work starts.
What we need to know
Before you ask for a quote, gather:
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711 or email us.
What happens if it’s left?
After an incident, an insurer can ask to see proof of TR19 cleaning and inspection. Without them, a claim can be reduced or refused. An up-to-date inspection report is a good place to start. It’s simpler to plan the work at Great Amwell now than to arrange it in a hurry later.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.

Different parts, different methods
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. They’re included in the readings and photos.
Canopy and plenum
Filters can look fine while the plenum behind them is heavily coated. That is why we test behind them.
