TR19 inspection in Hudnall
Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). From the numbers, you can see whether cleaning is due. Typical jobs include systems that need surveying before cleaning and kitchens whose menu or hours have changed, across post-clean checks, insurer audits and deposit thickness tests.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Hudnall questions
Can school kitchens in Hudnall be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Hudnall. Send us your term dates when you phone us on 0345 646 2711 or use the quote form, and we will fit the work in.
Which fire authority looks after Hudnall?
It’s Hertfordshire Fire and Rescue Service, which covers Hudnall. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can you verify a clean after it’s been done?
Post-clean verification is a check after a clean, with fresh grease readings and photos. It can follow our own cleans or another contractor’s.
Do you carry out TR19 audits for insurers?
Yes, for kitchens across the South East and London. Tell us what your insurer has asked for and we will set the report out to match.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Can you quote from photos?
Usually, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and we normally come back within one working day. Some sites still need a visit, and we’ll say so.
Do you look at the system first?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
What if parts of the system cannot be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Why deal with it now?
Without readings, you’re guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, which you won’t know without measuring. If the system at a site near Hudnall fails, there may be nowhere nearby to move to.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What you get with us
- Work around your opening hours, with 24/7 emergency cover
- Fully insured
- We diagnose before we treat
- A fixed price before any work starts

What else we do in Hudnall
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Clean grease off the canopy between professional cleans
- Have the latest report ready for insurance renewals
- Mention new equipment or longer hours at the next test
- Keep TR19 certificates, readings and reports together
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can quote to do it.
Close the access gaps found during inspection, so every part of the duct can be cleaned.
Staff cleaning versus specialist work
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.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
How the job changes from site to site
Restaurants, pubs and hotels
Inspections are done when the kitchen is closed or quiet so the kitchen keeps cooking.
Extract fan and discharge
We look at where the extract discharges outside, as grease can build up there too.
What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes an hour or two for a single kitchen, longer for a large or complex system, and we clear up before we go. In a small place like Hudnall, the journey is planned ahead and the visit arranged around the site’s hours.
- The visit is arranged for when the kitchen is not busy.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- We photograph the test points and record any sections we can’t reach.
- You get a report with readings, photos and recommendations.
How to prepare
- Mention any parking or loading restrictions
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one
Get a fixed quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before we start.

When it’s something else
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Hidden runs that need access panels first
- Installation problems, which fall under design guidance such as DW172
- Fire safety duties beyond the extract system
If you are not sure, just call us on 0345 646 2711, or email photos and we will give you a straight answer.
What the work covers
- Insurer audits
- Post-clean checks
- Deposit thickness tests
- Pre-clean surveys
- Access surveys
- Wet film thickness tests
What affects the quote in Hudnall
The price is fixed before any work begins. It’s based on:
- The number of sites or systems
- Parking and loading at the site
- One-off work versus a regular cycle
- How easy every part is to reach
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before work begins.
Asking for a quote
When you contact us, it’s useful to have:
- The times we could work without disrupting the site
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
We don’t publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, call us on 0345 646 2711 or drop us a line.
TR19 inspection in Hudnall: the local picture
In Hudnall, food businesses are inspected by environmental health officers from Dacorum council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for Hudnall is Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
