Hertfordshire · TR19 inspections and grease testing
TR19 inspections and grease testing in Highfield, Hertfordshire
TR19 inspection across Highfield and nearby, timed so the site keeps working and signed off in writing with photos.
- Sections of duct that cannot be reached
- Systems cleaned on a calendar with no measurements
- Ductwork where grease may be over the TR19 limits
How it works
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes a couple of hours for a typical kitchen extract system. Evenings, weekends or a closed day all work for a site in a place like Highfield.
- We agree a time when the kitchen is closed or quiet.
- 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 cannot reach.
- The findings go into a report with readings, photos and a recommended next clean.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Name a contact who can let us in at the agreed time
- Clear the space around the work
Getting a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, call 0345 646 2711, or email photos.
Advice
How we handle TR19 inspection in Highfield
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. We’re often asked to deal with ductwork where grease may be over the TR19 limits and uncertainty over how often to clean, on insurer audits, pre-clean surveys and post-clean checks.
Size does not change the work: a kitchen in a place like Highfield gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Part by part
Vertical risers
Risers can be hard to get into. The survey shows exactly what access there is.
Horizontal duct runs
Grease can gather thickly at bends and along long runs, well away from where anyone looks.
What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
What affects the cost of TR19 inspection
You will get a fixed price before we start. It takes into account:
- When the work can happen, such as evenings, overnight or weekends
- The condition we find in the survey
- One-off work versus a regular cycle
- Where the site is and how we reach it
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.
Asking for a quote
You do not need the technical terms. Just send:
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Detail shots of panels, filters and grilles
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
Signs you need TR19 inspection in Highfield
Looking at a canopy tells you little about what’s in the duct. A system can look clean at the filters and be heavily coated further in, so readings are the reliable guide.
Clients typically contact us when they notice something like this:
- An insurer’s request for a TR19 audit
- Pre-clean surveys before a first TR19 clean
- Extracts that have never been grease tested
- Kitchens whose menu or hours have changed
If your kitchen is in a listed or historic building, like the houses around Highfield (Batchwood Hall is about 4.4 miles east), fitting access panels needs care.

Why it’s worth doing now in Highfield
A pre-clean survey avoids surprises on the night. Access problems are spotted in advance rather than on the night, and the quote reflects the real job. In a smaller place like Highfield, a site that has to close is felt quickly.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, give us a ring on 0345 646 2711, or send details by email for straight advice and a fixed quote.

Questions from Highfield
Who is the fire and rescue service for Highfield?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Highfield. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Who carries out food hygiene inspections in Highfield?
Food hygiene inspections in Highfield are carried out by Dacorum council. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Which sectors do you work in?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Can you quote from photos?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
How long does grease testing take?
It takes a morning or less for one kitchen, more where there are several systems. The visit is timed so cooking isn’t disrupted.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Do you check other contractors’ cleans?
Verification means repeat readings and pictures once the clean is done. The report flags anything missed.
What happens if you cannot reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.

Our report lists what was cleaned and when, which is useful to have ready. The fire and rescue service for Highfield is Hertfordshire Fire and Rescue Service.
