Abbots Langley TR19 inspection
Specialist TR19 inspection for Abbots Langley: diagnosis first, then a fixed quote, the work and a report with photos. Call for a fixed quote.
- Insurers asking for TR19 evidence
- Cleaning intervals that may not suit the kitchen
- Extracts that have never been grease tested
How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. The work itself takes an hour or two for a single kitchen, longer for a large or complex system. Everything the job in Abbots Langley needs is worked out beforehand, from the survey.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- 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
- Move anything stored near the system
- Tell us the best time to work, such as after service or at a weekend
- Name a contact who can let us in at the agreed time

About our TR19 inspection in Abbots Langley
Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Testing is how you know where your system stands. If you are dealing with heavy grease suspected in the plenum or ducts and sections of duct that can’t be reached, we can put it right, from wet film thickness tests, insurer audits and pre-clean surveys onwards.
In a smaller place like Abbots Langley, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Abbots Langley kitchens: local notes
The FSA’s food hygiene register shows about 37 cafés, restaurants and staff canteens and about 21 sandwich bars and takeaways within roughly a mile and a half of the centre of Abbots Langley. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Food hygiene inspections in Abbots Langley are the job of Three Rivers council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Abbots Langley falls to Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If you look after a school kitchen, at a school such as Tanners Wood Junior Mixed and Infant School or anywhere near Abbots Langley, the holidays are the usual time for a TR19® clean. Commuter trade near Kings Langley station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

Abbots Langley’s nearest station is Kings Langley station, roughly 0.9 miles west of the centre.

Different parts, different methods
Extract fan and discharge
A greasy fan works harder and wears faster. Readings show if it needs attention before the next clean.
Canopy and plenum
We look over the canopy, inside and out, and note where grease has gathered.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
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.

Abbots Langley: your questions answered
Can the work in Abbots Langley be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Abbots Langley keeps running as normal. Just call 0345 646 2711 or email us with your opening times and we will plan around them.
Who would carry out a food hygiene inspection at a kitchen in Abbots Langley?
Food hygiene inspections in Abbots Langley are carried out by Three Rivers council. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
How do you measure grease in a kitchen extract?
WFTT and DTT are the two methods for measuring grease thickness, in microns. Readings are taken at set points through the system.
What should I send you?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
Do you work in Abbots Langley?
Yes. Our technicians work in Abbots Langley, within the South East and London area we cover.
Do you carry out TR19 audits for insurers?
Yes. Insurers often want evidence the extract is managed to TR19®, and our audit gives a clear record of the system’s condition, along with any actions needed.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Do you need TR19 inspection in Abbots Langley?
Kitchens change: a new menu, longer hours or more frying can all add grease. The old cleaning schedule may not match the kitchen any more.
Look out for any of the following:
- Heavy grease suspected in the plenum or ducts
- Sites with gaps in their extract records
- Sections of duct that can’t be reached
- Confirming a clean reached the whole system
A hall kitchen that only cooks for events, whether near Church of St Lawrence the Martyr or elsewhere in Abbots Langley, still needs its extract cleaned, just less often.

What affects the quote in Abbots Langley
Sites vary more than people expect. What affects the quote:
- How big the system is
- Site requirements such as sign-in and permits
- What state the system is in
- Parking and loading at the site
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before we start.
What we need to know
When you contact us, these details help:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711, or email photos.
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
