How we handle TR19 inspection in Langley Bottom
Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Langley Bottom and across Hertfordshire a clear record of the system’s condition. Common call-outs are for heavy grease suspected in the plenum or ducts and extracts that have never been grease tested, across wet film thickness tests, insurer audits and post-clean checks.
For a kitchen in or near Langley Bottom, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Good records are part of the job. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Keep to the recommended interval
- Do not box in or cover duct access panels
- Have the latest report ready for insurance renewals
- Wipe the canopy surfaces regularly
After post-clean verification, file the results with the cleaning certificate. Together they show the system was cleaned and checked.
Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.
Multi-site and managed buildings
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
What TR19 inspection can’t fix
In fairness, some problems need a different fix:
- Parts of the duct nobody can reach yet
- Fire safety duties beyond the extract system
- Mechanical faults in the extract
If you are not sure, just give us a ring on 0345 646 2711, or email photos and we’ll give you a straight answer.

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Kitchen extracts in Langley Bottom
There are about 28 restaurants, cafés and works canteens and about 10 takeaways and sandwich shops in Langley Bottom and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Each kitchen extract among them can be measured for grease to set the right cleaning interval. Langley Bottom is covered by 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. Kitchens in Langley Bottom get their food hygiene inspections from North Hertfordshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked.

What happens if it’s left?
Catching heavy deposits early keeps the fix small. Ignored, the layer only gets thicker. It’s worth booking a check, because nobody sees inside a duct day to day.
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and the price is agreed before work begins.
