Potten End TR19 inspection
Looking for TR19 inspection in Potten End? We diagnose first, fix the price and book the work around your hours, finishing with a written report and photos.
- Sections of duct that cannot be reached
- Insurance renewals needing proof of TR19 cleaning
- Cleaning intervals that may not suit the kitchen
What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
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.
About our TR19 inspection in Potten End
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 are dealing with systems cleaned on a calendar with no measurements and confirming a clean reached the whole system, we can put it right, from post-clean checks, wet film thickness tests and deposit thickness tests onwards.
Somewhere as small as Potten End, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Facilities teams in offices, schools and healthcare sites book us too in Potten End and across Hertfordshire. Work can be phased by floor, building or site around the people who use them.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
What TR19 inspection looks like in Potten End
The FSA’s food hygiene register shows about 15 restaurants, cafés and works canteens and about 8 takeaways and sandwich shops within roughly a mile and a half of the centre of Potten End. For any of them with a canopy, measuring grease is better than guessing when to clean. Hertfordshire Fire and Rescue Service covers Potten End. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. In Potten End, food businesses are inspected by environmental health officers from Dacorum council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
A hospital like Hemel Hempstead Hospital, about 2.7 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. For schools such as Potten End CofE Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

FAQs for Potten End
Who is the fire and rescue service for Potten End?
It’s Hertfordshire Fire and Rescue Service, which covers Potten End. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you clean school canteen extracts around Potten End out of term?
Yes, holiday work suits schools best. Around Potten End, the Food Standards Agency lists about 10 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
How do you measure grease in a kitchen extract?
Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. The results are given in microns.
Do you cover Potten End?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Potten End.
Can you quote from pictures?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. Some sites still need a visit, and we’ll say so.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it 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. System size and access decide the rest.

Common problems we fix in Potten End
As hot, greasy air travels up the duct, it cools and leaves a film behind. It often collects where nobody can see it: the plenum, bends and horizontal runs.
The symptoms we are asked about most include:
- An insurer’s request for a TR19 audit
- Extracts that may be over the 200 micron mean
- Pre-clean surveys before a first TR19 clean
- Cleaning intervals that may not suit the kitchen
Volunteers running a hall kitchen near Church of the Holy Trinity, or anywhere in Potten End, may not know when the extract was last cleaned, and a grease test settles it.
What your quote should include
- How they set the interval to the next visit
- Whether the quote shows VAT
- If they look at the system before pricing
- How areas they can’t reach will be recorded
Different parts, different methods
Vertical risers
Vertical risers take the extract up through the floors. Grease can drain down and pool at the bottom, so we check there.
Extract fan and discharge
Grease on the fan adds to wear. The inspection shows whether it needs cleaning now.
When it’s something else
In fairness, some problems need a different fix:
- Design faults in the extract system
- Parts of the duct nobody can reach yet
- Fan breakdowns, which need a repair visit
If you’re not sure, just phone us on 0345 646 2711, or email photos and we will give you a straight answer before booking.

How the visit works
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards.

- We go through any past certificates and reports.
- We follow the extract from canopy to discharge.
- We note where access panels are and where more are needed.
- We measure the grease and photograph each point.
- We report back with readings and a fixed quote.
How to prepare
- Move anything stored near the system
- Let us know when the site is closed or quiet
- Make sure someone can let us in and lock up afterwards
