About our TR19 inspection in Flamstead
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. Common call-outs are for surveys needed before quoting a full clean and systems cleaned on a calendar with no measurements, across post-clean checks, deposit thickness tests and pre-clean surveys.
Work in a small place like Flamstead starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
A written report with photos 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.

What affects the quote in Flamstead
The quote reflects the site in front of us. We take into account:
- How easy every part is to reach
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
- Where the site is and what kind of site it is

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Installation problems, which fall under design guidance such as DW172
- Mechanical faults in the extract
- Heavy deposits found on test, which still need cleaning
Not sure which it is? You can call 0345 646 2711 or send us an email and we will tell you honestly.

Common questions in Flamstead
Who enforces fire safety at workplaces in Flamstead?
It’s Hertfordshire Fire and Rescue Service, which covers Flamstead. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Who would carry out a food hygiene inspection at a kitchen in Flamstead?
Food hygiene inspections in Flamstead are carried out by Dacorum council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, 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, depending on what the system needs.
Do you cover Flamstead?
Yes. Our technicians work in Flamstead, within the South East and London area we cover.
What happens if you cannot reach some of it?
We record them on the report, with photos where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
For landlords and multi-site operators
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Facilities teams in offices, schools and healthcare sites book us too in Flamstead and across Hertfordshire. Work can be phased by floor, building or site around the people who use them.
Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- Keep grease filters clean and fitted properly
- Book the next test on the date in the report
- File every inspection report with your certificates
- Keep the route to access panels clear
Any access problems we found are listed with a suggested fix. With panels fitted, the next clean can cover every section.
Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.
When to call us in Flamstead
Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Measuring it is the first step to keeping it under control.
Signs it’s time to call us include:
- Heavy grease suspected in the plenum or ducts
- Kitchens whose menu or hours have changed
- Sites with gaps in their extract records
- Checking the result of a recent clean
Healthcare kitchens, like those at hospitals such as Hemel Hempstead Hospital (about 5 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.
Questions to ask before booking
- Proof of accreditation you can verify
- What happens if part of the system cannot be accessed
- Whether the quote shows VAT
- Whether they’re fully insured
Grease, kitchens and Flamstead
The Food Standards Agency lists about 4 pubs, bars and clubs as registered food businesses within 1.5 miles or so of the middle of Flamstead. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. The fire and rescue service for Flamstead is Hertfordshire 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. Environmental health officers from Dacorum council inspect food businesses in Flamstead. 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.
Where a hall near Church of St Leonard, or anywhere in Flamstead, hosts lunch clubs or events, its extract gathers grease just as a café’s does. For schools such as Flamstead Village School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Why it’s worth doing now in Flamstead
Without readings, you are guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. Systems in rural buildings are often out of sight and out of mind.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, phone us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.
