How we handle TR19 inspection in Langley
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Langley and across Hertfordshire a clear record of the system’s condition. Typical jobs include extracts that may be over the 200 micron mean and an insurer’s request for a TR19 audit, across post-clean checks, deposit thickness tests and insurer audits.
In a small place like Langley, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Managing agents and facilities teams in Langley
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
How we price TR19 inspection
Your quote is based on your site. We consider:
- Whether we need access equipment or extra panels
- A single visit or a regular plan
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before any work starts.
What we need to know
When you call or email, it’s useful to have:
- The site address and the type of premises
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
FAQs for Langley
Who would carry out a food hygiene inspection at a kitchen in Langley?
The local authority for Langley is North Hertfordshire council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Which fire authority looks after Langley?
Langley is in the area of Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
What about areas you can’t get to?
Anything we can’t reach goes on the report, with pictures where possible, and we tell you what would make it reachable, for example new access panels.
Do we have to follow TR19 by law?
No. TR19® is a specification, not a statute. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so it matters in practice.
How often should a kitchen extract be inspected?
Enough to be sure grease stays within the TR19® Grease figures between cleans. If readings rise, the interval should shorten.
What do you do with what you remove?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
What does a pre-clean survey involve?
The survey covers the whole system, grease readings and access to each section. It lets us plan the clean and send you a fixed quote.
Can you work evenings and weekends?
Yes. Tell us your opening hours when you ask for a quote and we’ll book around them.
TR19 inspection around Langley
The FSA’s food hygiene register includes about 4 pubs and bars in and around Langley, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Langley get their food hygiene inspections from North Hertfordshire council. 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. Langley sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Bursars and site managers at schools such as The Thomas Alleyne School tend to book extract cleaning for when the kitchen is empty. A hospital like Lister Hospital, about 2.7 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

What we are called out for in Langley
TR19® is the benchmark that insurers, fire officers and EHOs refer to. It isn’t legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and grease in the extract is part of that risk.
Keep an eye out for these warning signs:
- Insurers asking for TR19 evidence
- Sections of duct that can’t be reached
- Missing TR19 certificates or history
- Systems cleaned on a calendar with no measurements
Knebworth House, about 1.3 miles south-east, is one of the historic houses near Langley; if you run event catering at a venue like that, cleans can be booked between functions.
Questions to ask before you book

Part by part
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. We check and test them as part of the inspection.
Canopy and plenum
The plenum behind the filters can carry a lot of grease. Readings and pictures are taken in the plenum on every inspection.
When it’s something else
TR19 inspection cannot fix everything, and we’d rather say so up front. It doesn’t solve:
- The responsible person’s own fire risk assessment
- Heavy deposits found on test, which still need cleaning
- Fan breakdowns, which need a repair visit
If in doubt, ring 0345 646 2711 or email us and we will say what we think.
What the work covers
- Deposit thickness tests
- Pre-clean surveys
- Wet film thickness tests
- Post-clean checks
- Access surveys
- Insurer audits
What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes around an hour or two per canopy and duct system. Visits to a village like Langley are booked in advance, at a time that suits whoever runs the site.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- We send a report setting out the readings, pictures and next steps.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
Getting a quote
Getting a quote doesn’t take long. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
