TR19 inspection in High Ongar, done properly
Think of a TR19 inspection as the diagnosis before the treatment. Readings, photos and notes on access are gathered from end to end, so the clean can be planned properly. The work covers access surveys, pre-clean surveys and post-clean checks, and people most often call us about confirming a clean reached the whole system and kitchens taken over with no cleaning records.
Work in a small place like High Ongar starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
A written report with pictures follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Keep grease filters clean and fitted properly
- Don’t box in or cover duct access panels
- Store grease readings where your insurer can see them
- Keep to the recommended interval
Keep the verification report next to the certificate it relates to. Together they show the system was cleaned and checked.
Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.

What else we do in High Ongar
What we do, step by step
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and floors and nearby surfaces are sheeted. On site, it takes a morning or less for one kitchen, more where there are several systems. Pictures of the system and its access let us plan the work in High Ongar before we set off.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- We report the findings and flag any areas that need more work.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Tell us about site rules, permits or sign-in
- Have your last certificate or report to hand

High Ongar kitchens: local notes
Look up High Ongar on the FSA’s food hygiene register and you will find about 19 cafés, restaurants and staff canteens and about 5 takeaways within about 1.5 miles of central High Ongar. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. High Ongar is covered by Essex County Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. It’s Epping Forest council that sends environmental health officers to food businesses in High Ongar. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.
If you run a church or community hall kitchen, near Church of St Mary the Virgin or elsewhere in High Ongar, its extract still collects grease from every lunch and event. For schools such as High Ongar Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

When it’s something else
To be straight with you, there are a few things this work will not fix:
- The legal duty, which stays with the responsible person
- A faulty or failing extract fan
- Hidden runs that need access panels first
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we will tell you honestly.
Parts of the system we cover
- Wet film thickness tests
- Insurer audits
- Post-clean checks
- Pre-clean surveys
- Deposit thickness tests
- Access surveys
Leave it or put it right?
Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Ignored, the layer only gets thicker. Out of sight is the usual reason a rural system goes too long without attention.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or use the quote form, and we’ll explain what it covers.

Fixed quotes for TR19 inspection in High Ongar
Every site gets its own quote. These are the things that affect it:
- Parking and loading at the site
- Site requirements such as sign-in and permits
- The times the site is available
- A single visit or a regular plan
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
When you contact us, these details help:
- Your opening hours and when the area is out of use
- Any previous report or certificate
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Common questions in High Ongar
Which environmental health team covers High Ongar?
Food hygiene inspections in High Ongar are carried out by Epping Forest council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Will you come out to High Ongar?
Yes, we work in villages as well as towns, and High Ongar is covered. The journey is planned ahead, so a few details about the route help.
Will you produce a report for our insurer?
Yes. Our TR19 audits cover readings, pictures, access and a recommended cleaning interval. You can pass it straight to your insurer or broker.
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.
Do you work out of hours?
Yes, and that’s how we prefer to work. The visit is timed for when the area isn’t in use, whether that’s late evening, overnight or a weekend.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What if parts of the system cannot be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
For landlords and multi-site operators
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
