Wyddial TR19 inspection
Need TR19 inspection in Wyddial? We diagnose first, fix the price and book the work around your hours, then sign off with a report and pictures.

- Surveys needed before quoting a full clean
- Ductwork where grease may be over the TR19 limits
How we handle TR19 inspection in Wyddial
BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Grease testing shows whether your kitchen needs cleaning more often than that. Common call-outs are for extracts that may be over the 200 micron mean and uncertainty over how often to clean, on pre-clean surveys, wet film thickness tests and insurer audits.
Somewhere as small as Wyddial, 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.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
What TR19 inspection cannot fix
It’s worth knowing the limits before booking:
- The grease itself, which needs a full or spot clean
- Installation problems, which fall under design guidance such as DW172
- Parts of the duct nobody can reach yet
If you’re not sure, just call 0345 646 2711 or send us an email and we’ll give you a straight answer before you book.

What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
FAQs for Wyddial
Which council inspects kitchens in Wyddial?
The local authority for Wyddial is East Hertfordshire council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Who enforces fire safety at workplaces in Wyddial?
Wyddial 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 one contract cover all our sites?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What does TR19 inspection cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
Is there a survey before the work?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Is a quote from photos possible?
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.
Can you verify a clean after it’s been done?
Post-clean verification is a check after a clean, with fresh grease readings and photos. It can follow our own cleans or another contractor’s.
Grease, kitchens and Wyddial
There are about 11 restaurants, cafés and works canteens and about 5 takeaways in and around Wyddial, up to about a mile and a half 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. Wyddial sits within the area of 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. It’s East Hertfordshire council that sends environmental health officers to food businesses in Wyddial. 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.
For schools such as Layston Church of England First School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. A hall kitchen that only cooks for events, whether near Church of St Giles or elsewhere in Wyddial, still needs its extract cleaned, just less often.

How the job changes from site to site
Vertical risers
Vertical risers take the extract up through the floors. Grease can run down and collect at the base, so we check there.
Extract fan and discharge
Grease on the fan adds to wear. The inspection shows whether it needs cleaning now.
