Hertfordshire · TR19 inspections and grease testing
Haldens TR19 inspection
TR19 inspection for Haldens, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Insurers asking for TR19 evidence
- Post-clean verification after another contractor’s clean
- Pre-clean surveys before a first TR19 clean
Signs you need TR19 inspection in Haldens
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and grease in the extract is part of that risk.
What we’re most often called out for:
- Ductwork where grease may be over the TR19 limits
- Pre-clean surveys before a first TR19 clean
- Uncertainty over how often to clean
- Insurers asking for TR19 evidence
If you run a café or takeaway near Welwyn North station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
Questions to ask before booking
- Whether they’re fully insured
- What hours they’ll be on site
- Proof of accreditation you can verify
- What records you’ll receive afterwards
TR19 inspection in Haldens, done properly
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 Haldens and across Hertfordshire a clear record of the system’s condition. If you have heavy grease suspected in the plenum or ducts and systems that need surveying before cleaning, we can put it right, from access surveys, insurer audits and wet film thickness tests onwards.
Size doesn’t change the work: a kitchen in a place like Haldens gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What TR19 inspection cannot fix
We will always give you a straight diagnosis, so here’s what TR19 inspection won’t do:
- A faulty or failing extract fan
- The responsible person’s own fire risk assessment
- Hidden runs that need access panels first

- Wet film thickness tests

What we do, step by step
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. For a site near Haldens, the work is booked around your opening hours, evenings and weekends included.
- We agree a time when the kitchen is closed or quiet.
- Every part of the system is examined, end to end.
- Grease thickness is measured at set points by WFTT or DTT.
- We photograph the test points and record any sections we can’t reach.
- You get a report with readings, pictures and recommendations.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any sign-in, permit or induction we need

Haldens questions
Can you come to Haldens after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Haldens does not have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
Who is the fire and rescue service for Haldens?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Haldens. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
How much does TR19 inspection cost in Haldens?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we will typically reply within one working day.
How long does a TR19 inspection take?
Testing takes a couple of hours for a typical kitchen extract system. Sites with several canopies take longer, and you can ring 0345 646 2711 or use the quote form to book it in.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
How do you measure grease in a kitchen extract?
Grease thickness testing measures the layer of grease on the duct surfaces, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). Each reading is recorded in microns.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Why act early in Haldens
Do not wait for an EHO visit or insurance renewal to find gaps in your extract records. A recent inspection report means you are ready when asked. When a site near Haldens shuts unexpectedly, the people who rely on it notice at once.

Grease, kitchens and Haldens
The Food Standards Agency lists about 9 pubs, bars and clubs as registered food businesses in Haldens and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Haldens sits within the area of Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s Welwyn Hatfield council that sends environmental health officers to food businesses in Haldens. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand.
A hall kitchen that only cooks for events, whether near Christ the King or elsewhere in Haldens, still needs its extract cleaned, just less often. Bursars and site managers at schools such as Waterside Academy tend to book extract cleaning for when the kitchen is empty.
Haldens is about 1 mile north of Welwyn Garden City, in Hertfordshire. We provide TR19 inspection for businesses, landlords and public buildings in Haldens and the rest of Hertfordshire.

What’s near Haldens
In Haldens, that means kitchens and buildings near Sir Frederic Osborn School and The Sheldan Inn, among other places. The closest station to Haldens is Welwyn North station, about 0.8 miles north.

Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Flag oily drips near the extract
- Book the next test on the date in the report
- Clean grease off the canopy between professional cleans
- Clean or swap grease filters as often as the kitchen needs
The audit report is set out to pass straight to your insurer or broker, with readings, pictures and any areas not accessible.
Keep all TR19 records together so the history is easy to show.
How we price TR19 inspection
The quote reflects the site in front of us. We take into account:
- Access, including roofs, risers and ceiling voids
- What state the system is in
- Whether it’s a one-off visit or part of a schedule
- How many systems or sites are involved
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, ring 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.
Helping us quote
To speed up the quote, send us:
- Wide pictures of the system and the area around it
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
- Where the site is and what kind of site it is
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
