Hertfordshire · TR19 inspections and grease testing
TR19 inspections in Radwell
For TR19 inspections and grease testing in Radwell, one call is all it takes: survey, fixed quote, work and sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Missing access panels found on survey
- Post-clean verification after another contractor’s clean
- Extracts that may be over the 200 micron mean
What the work involves, part by part
Extract fan and discharge
The discharge at the end of the system is checked as well, as grease can build up there too.
Horizontal duct runs
If a run has no access panel, we note it so it can be fixed before the clean.
TR19 inspection for kitchens and businesses in Radwell
Taking on a kitchen in Radwell with no cleaning records? Start with an inspection. We survey the system, measure the grease and tell you what needs doing, so the next step is based on facts. If you have uncertainty over how often to clean and parts of the system left out of past cleans, we can help, from pre-clean surveys, insurer audits and access surveys onwards.
Somewhere as small as Radwell, 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.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Honest limits
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- The grease itself, which needs a full or spot clean
- Hidden runs that need access panels first
- Fan breakdowns, which need a repair visit
If you are not sure, just call 0345 646 2711 or send us an email and we’ll give you a straight answer.

Radwell: your questions answered
Is Radwell within the area you cover?
Yes. Radwell is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Which fire service covers Radwell?
Radwell is in the area of Hertfordshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can the work be done while we’re closed?
Yes. Evenings, nights and weekends are normal working hours for us, so the site doesn’t lose a service.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Every site has its own report.
Is a quote from pictures possible?
Usually, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote typically follows within one working day. If pictures aren’t enough, we’ll survey first.
When should we have our next grease test?
We suggest a next test date in every report, taking the readings and the kitchen’s hours into account. The interval should come from a competent person’s risk assessment backed by grease measurement.
How far ahead should we book?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What happens if you cannot reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Radwell kitchens: local notes
Food Standards Agency records include about 10 pubs, bars and clubs within about 1.5 miles of central Radwell. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Radwell is covered by Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. It’s North Hertfordshire council that sends environmental health officers to food businesses in Radwell. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Healthcare kitchens, like those at hospitals such as Fairfield Hospital (about 1.9 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands. Where a hall near Church of All Saints, or anywhere in Radwell, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Hinxworth Place is about 2.4 miles north), access may need planning.
Radwell is about 2 miles north of Letchworth, in Hertfordshire. Radwell gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with pictures. Radwell is one of 381 places in Hertfordshire where we work for commercial clients. Milton Keynes is in our area too, around 24 miles away.

Local landmarks in Radwell
In Radwell, that means kitchens and buildings near The Knights Templar School, Norton School and The Chequers Public House. Radwell’s nearest station is Baldock station, about 1.2 miles south-east. Well-known places in the area include Bygrave House (2 miles east) and Fairfield Hospital (1.9 miles west). For a walk, there’s Arlesey Old Moat and Glebe Meadows.
Why it’s worth doing now in Radwell
After an incident, an insurer can ask to see proof of TR19 cleaning and inspection. Missing records can put a claim at risk. An up-to-date inspection report is a good place to start. In a place like Radwell, ductwork and fans are easy to forget until something goes wrong.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

What your team can do, and what needs us
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. Cleaning inside ducts and units is specialist work.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Share inspection reports with your insurer or broker when asked
- Report grease dripping from the canopy
- Never cook with filters missing
- File every inspection report with your certificates
The audit report is set out to pass straight to your insurer or broker, including readings, pictures and any inaccessible sections.
Close the access gaps found during inspection, so grease is not left building in hidden parts.
The process
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. A few pictures of the system help us make the most of a visit to a place like Radwell.
- 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.
- Each test point and any access problems are photographed.
- The findings go into a report with readings, photos and a recommended next clean.
Preparing for the visit
- Mention any parking or loading restrictions
- Mention any sign-in, permit or induction we need
- Plan for cooking equipment or plant to be off before we arrive
