What TR19 inspection can’t fix
Not every problem is solved by TR19 inspection, and we’d rather say so up front. It will not put right:
- Parts of the duct nobody can reach yet
- The responsible person’s own fire risk assessment
- A faulty or failing extract fan
If you are not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer before booking.

TR19 inspection in Cholesbury
A pre-clean survey looks at the whole system, from canopy to discharge. We check where the access panels are and whether every section can be reached, and record grease readings at set points. If you have missing access panels found on survey and insurance renewals needing proof of TR19 cleaning, we can put it right, from wet film thickness tests, pre-clean surveys and access surveys onwards.
In a small place like Cholesbury, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Pictures of the system and its access let us plan the work in Cholesbury before we set off.
- First we book a time that won’t disrupt cooking.
- Every part of the system is examined, end to end.
- Grease thickness is measured at set points by WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- You get a report with readings, pictures and recommendations.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down
- Move anything stored near the system
Get a fixed quote
The quickest way to a quote is to send photos: 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 we can price many jobs without a visit.

When to call us in Cholesbury
You can’t judge grease thickness by eye. Clean filters can hide a heavy layer behind them, so readings are the reliable guide.
Most sites get in touch when they notice one of these:
- Cleaning intervals that may not suit the kitchen
- Kitchen extract systems with no recent grease readings
- Post-clean verification after another contractor’s clean
- Insurance renewals needing proof of TR19 cleaning
Cholesbury Manor House, about 0.1 miles west, is one of the historic houses near Cholesbury; if you run event catering at a venue like that, cleans can be booked between functions.
What to look for in a quote
- Whether they recommend a next date
- What records you’ll receive afterwards
- Whether the work can be done while the site is closed
- Whether the price is fixed
What happens if it’s left?
Sites in Cholesbury that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Measured readings let a competent person set the interval. In a place like Cholesbury, ductwork and fans are easy to forget until something goes wrong.
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711, or email photos, and we’ll explain what it covers.
Why us?
- We are fully insured
- A written report with pictures after every visit

Between visits
So the system stays in good health:
- Keep the route to access panels clear
- Flag changes in how much frying the kitchen does
- Clean grease off the canopy between professional cleans
- Report grease dripping from the canopy
Each report suggests the next clean and the next test, based on the readings and how the kitchen is used.
Keep filters clean and in place. Gaps around filters let grease get past them.
TR19 inspection in Cholesbury: the local picture
The fire and rescue service for Cholesbury is Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Cholesbury is about 30 miles from central London, well within the area we cover across London and the South East. Visits are booked around your hours, evenings and weekends included.
A hospital like Chiltern Hospital, about 4.8 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run a church or community hall kitchen, near Church of St Lawrence or elsewhere in Cholesbury, its extract still collects grease from every lunch and event.

In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Questions from Cholesbury
Do you work at weekends in Cholesbury?
Yes, out-of-hours work is a big part of what we do. The work in Cholesbury can fit around your hours. When you give us a ring on 0345 646 2711 or drop us a line, mention when the site is quiet.
Do you cover smaller places like Cholesbury?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Will you produce a report for our insurer?
Yes. We inspect the system and produce a report with grease readings, pictures and any inaccessible areas. It’s set out for your insurer or broker.
What information do you need?
Some photos and a quick description of the system plus the address and your hours. If we need more, we’ll ask.
What happens if you can’t reach some of it?
We record them on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
How often should a kitchen extract be inspected?
That varies with the kitchen’s daily use. BESA sets minimum cleaning intervals of 3, 6 or 12 months by daily use, and testing shows if your kitchen needs more.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
Do you have a 24/7 line?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
