TR19 inspection for kitchens and businesses in Blackmore End
A grease test measures how thick the grease is inside a kitchen extract system. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). The results show whether the system needs cleaning and how soon. We’re often asked to deal with surveys needed before quoting a full clean and insurance renewals needing proof of TR19 cleaning, on wet film thickness tests, deposit thickness tests and insurer audits.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What the work involves, part by part
Schools, hospitals and care homes
Hospital and care home kitchens can cook all day, every day. Testing shows if the cleaning interval keeps pace.
Extract fan and discharge
The extract fan and its housing collect grease too. We check and test them as part of the inspection.
What affects the quote in Blackmore End
You will get a fixed price before work begins. It takes into account:
- Any permits to work or inductions
- A single visit or a regular plan
- The number of sites or systems
- Travel, parking and unloading
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

- Any previous report or certificate

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.
TR19 inspection in Blackmore End: the local picture
The FSA’s food hygiene register shows about 4 restaurants, cafés and works canteens within roughly a mile and a half of the centre of Blackmore End. Each kitchen extract among them can be measured for grease to set the right cleaning interval. It’s St Albans City council that sends environmental health officers to food businesses in Blackmore End. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for Blackmore End is Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you look after a school kitchen, at a school such as Kimpton Primary School or anywhere near Blackmore End, the holidays are the usual time for a TR19® clean. Historic houses near Blackmore End, such as Shaw's Corner about 1.6 miles east, are a reminder that older buildings with event kitchens can have long, awkward duct routes. Church and community hall kitchens, near St Peter or anywhere around Blackmore End, are easy to forget, but their extracts collect grease like any other.

Common questions in Blackmore End
Can school kitchens in Blackmore End be cleaned in the holidays?
Yes. The holidays are the usual time for school work. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Blackmore End, it pays to plan holiday dates ahead. You can phone us on 0345 646 2711 or drop us a line with the dates the site is empty.
Can you get to a site in Blackmore End?
Yes, we work in villages as well as towns, and Blackmore End is covered. Photos of the system and directions to the site help us plan the visit.
Can you work evenings and weekends?
Yes. Give us your opening hours with your enquiry and we’ll book around them.
Can you quote from photos?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What about areas you can’t get to?
Anything we cannot reach goes on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
What is a WFTT or DTT grease test?
Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. Each reading is recorded in microns.
Is TR19 cleaning the law?
No. TR19® is a specification, not a statute. Without TR19 records, an insurance claim can be reduced or refused, so following it is the sensible course.
Managing agents and facilities teams in Blackmore End
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
How it works
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes around an hour or two per canopy and duct system. We agree a date with you, plan the drive to Blackmore End and turn up when the site is quiet.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Getting ready for the visit
- Arrange a key holder or contact on site
- Clear the space around the work
- Mention any sign-in, permit or induction we need
Getting a quote
For a fixed quote, call 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
Advice
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Keep to the recommended interval
- Send TR19 audit reports to your insurer on request
- Keep TR19 certificates, readings and reports together
- Clean grease off the canopy between professional cleans
Where sections couldn’t be reached, the report says where access panels would help. With panels fitted, the next clean can cover every section.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.

What a clean won’t put right
To be straight with you, there are a few things this work will not fix:
- Parts of the duct nobody can reach yet
- The grease itself, which needs a full or spot clean
- Fire safety duties beyond the extract system
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we will give you a straight answer.

In-house cleaning or a specialist?
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.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
