About our TR19 inspection in Clothall
A grease test measures how thick the grease is inside a kitchen extract system. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). The results show whether the system needs cleaning and how soon. If you’re dealing with extracts that may be over the 200 micron mean and surveys needed before quoting a full clean, we can help, from deposit thickness tests, pre-clean surveys and post-clean checks onwards.
In a village or hamlet like Clothall, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the job changes from site to site
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. We check and test them as part of the inspection.
Schools, hospitals and care homes
Inspections are planned around mealtimes and holidays to avoid disruption.
Fixed quotes for TR19 inspection in Clothall
A fixed price needs a few facts first. We look at:
- Access, including roofs, risers and ceiling voids
- The scale of the work
- The number of sites or systems
- Where the site is and how we reach it
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and the price is agreed before we start.
What we need to know
When you call or email, it’s useful to have:
- The roof, plant room or outside wall the system runs to
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
What happens if it’s left?
Sites in Clothall that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Measured readings let a competent person set the interval. Somewhere as small as Clothall, losing a kitchen or building to a fault is felt by everyone who uses it.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, give us a ring on 0345 646 2711 or drop us a line for straight advice and a fixed quote.

Keeping the system healthy
To keep the system working properly between visits:
- Clean or swap grease filters as often as the kitchen needs
- Wipe the canopy surfaces regularly
- Keep to the recommended interval
- Flag changes in how much frying the kitchen does
Each report suggests the next clean and the next test, from the measured grease and the kitchen’s hours.
Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.
Common questions in Clothall
Do you do school kitchen extract cleaning in Clothall in the summer holidays?
Yes, holiday work suits schools best. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Clothall. Just ring 0345 646 2711 or email us with your term dates and we’ll plan around them.
Who enforces fire safety at workplaces in Clothall?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Clothall. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
How much time does an inspection need?
An inspection takes a morning or less for one kitchen, more where there are several systems. Large or multiple systems take longer, so give us a ring on 0345 646 2711 or use the quote form and we will plan it.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Is Clothall in your area?
Yes. Clothall is part of the area we cover, within the South East and London area we cover.
What is post-clean verification?
A post-clean check records grease readings and photos after the work, for our cleans and other firms’ alike.
Is TR19 cleaning the law?
No. TR19® is a specification, not a statute. Without TR19 records, an insurance claim can be reduced or refused, so following it is the sensible course.
What information do you need?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.

What TR19 inspection looks like in Clothall
Look up Clothall on the FSA’s food hygiene register and you’ll find about 3 restaurants, cafés and works canteens within roughly a mile and a half of the centre of Clothall. For any of them with a canopy, measuring grease is better than guessing when to clean. In Clothall, food businesses are inspected by environmental health officers from North Hertfordshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. Clothall is covered by 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.
If you run catering at a healthcare site, such as a hospital like Lister Hospital about 4.1 miles south-west, the extract may need cleaning more often than a part-time kitchen. For schools such as Weston Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

What we do, step by step
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes around an hour or two per canopy and duct system. Somewhere as small as Clothall, the date and timings are agreed with you well before the day.
- We agree a time when the kitchen is closed or quiet.
- Every part of the system is examined, end to end.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- You get a report with readings, photos and recommendations.
Getting ready for the visit
- Arrange a key holder or contact on site
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Common problems we fix in Clothall
Grease is fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Measuring it is the first step to keeping it under control.
Any of these means the system needs a check-up:
- Post-clean verification after another contractor’s clean
- Extracts that have never been grease tested
- Sections of duct that can’t be reached
- An insurer’s request for a TR19 audit
If you run a church or community hall kitchen, near Church of St Mary or elsewhere in Clothall, its extract still collects grease from every lunch and event.
Questions to ask before booking
- If the quote is a fixed price or an estimate
- How VAT is shown on the quote
- What hours they’ll be on site
- When the next visit should be, and why
What staff can safely do
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, and that’s where we come in.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
