TR19 inspections in Duton Hill
TR19 inspection for businesses, landlords and public buildings in Duton Hill. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
TR19 inspection for kitchens and businesses in Duton Hill
Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. From the numbers, you can see whether cleaning is due. We are often asked to deal with kitchens whose menu or hours have changed and missing TR19 certificates or history, across wet film thickness tests, pre-clean surveys and access surveys.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

How the visit works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes a couple of hours for a typical kitchen extract system. A quick note on how to find the site and where to park makes a visit to Duton Hill run smoothly.
- 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.
- We photograph the test points and record any sections we cannot reach.
- The findings go into a report with readings, photos and a recommended next clean.
Getting ready for the visit
- Mention any parking or loading restrictions
- Mention any locked doors, roof access or ceiling voids
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Getting a quote doesn’t take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
FAQs for Duton Hill
Do you cover smaller places like Duton Hill?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Which fire authority looks after Duton Hill?
It’s Essex County Fire and Rescue Service, which covers Duton Hill. 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 often should a kitchen extract be inspected?
It depends on how heavily the kitchen cooks. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and testing shows if your kitchen needs more.
Why survey before a clean?
A survey finds out how the system is laid out, how dirty it is and what can be reached, so the clean goes to plan. Any access problems are flagged so they can be sorted first.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
How much notice do you need?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
When to call us in Duton Hill
Some parts of a system are hard to reach, so those sections can be skipped time and again. An inspection of a system in Duton Hill shows where access panels are missing, so the gaps can be closed.
Any of these means the system needs a check-up:
- Parts of the system left out of past cleans
- Systems that need surveying before cleaning
- Kitchens whose menu or hours have changed
- Heavy grease suspected in the plenum or ducts
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Horham Hall is about 1.9 miles north-west), access may need planning.
What to look for in a quote
- Whether inaccessible sections are listed on the report
- When the next visit should be, and why
- If they look at the system before pricing
- What paperwork you get at the end
When it’s something else
Not every problem is solved by TR19 inspection, and we’ll tell you before work begins. It will not put right:
- Mechanical faults in the extract
- Parts of the duct nobody can reach yet
- Removing the grease, which is a separate clean
If in doubt, call us on 0345 646 2711 or email us and we will say what we think.
Parts of the system we cover
- Pre-clean surveys
- Post-clean checks

Duton Hill kitchens: local notes
Food Standards Agency records include about 4 bars, pubs and nightclubs within about 1.5 miles of central Duton Hill. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Duton Hill is covered by Essex County 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. Food hygiene inspections in Duton Hill are the job of Uttlesford council’s environmental health team. 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.
For schools such as Putteridge High School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. A hall kitchen that only cooks for events, whether near Church of St Mary the Virgin or elsewhere in Duton Hill, still needs its extract cleaned, just less often.

How the job changes from site to site
Vertical risers
Risers can be hard to get into. We record what can and can’t be reached.
Horizontal duct runs
Grease settles on the floor of horizontal ducts as the air cools. We test at points along the run through access panels.
What affects the cost of TR19 inspection
The quote reflects the site in front of us. We take into account:
- The condition we find in the survey
- One-off work versus a regular cycle
- The times the site is available
- Whether several sites go on one quote
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before we start.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.
