TR19 inspection in Well End, done properly
Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). From the numbers, you can see whether cleaning is due. Typical jobs include kitchens whose menu or hours have changed and systems cleaned on a calendar with no measurements, across pre-clean surveys, post-clean checks and deposit thickness tests.
In a village or hamlet like Well End, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

The process
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a couple of hours for a typical kitchen extract system. If you can send photos, we can arrive in Well End knowing what to expect.
- The visit is arranged for when the kitchen is not busy.
- The system is checked from canopy to discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- Each test point and any access problems are photographed.
- The findings go into a report with readings, photos and a recommended next clean.
Preparing for the visit
- Agree a time when the area can be out of use
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one

What affects the quote in Well End
Your quote is based on your site. We take into account:
- Working hours and out-of-hours timing
- Site rules, permits and inductions
- What state the system is in
- How big the system is
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, ring 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
Helping us quote
When you call or email, it’s useful to have:
- The paperwork from the last visit, if you have it
- Your opening hours and when the area is out of use
- The site address and the type of premises
- Photos showing the whole system and its surroundings
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

For landlords and multi-site operators
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Well End: your questions answered
Who would carry out a food hygiene inspection at a kitchen in Well End?
Food hygiene inspections in Well End are carried out by Hertsmere council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can a school canteen extract in Well End be done out of term time?
Yes, holiday work suits schools best. The FSA’s register shows about 14 schools and colleges with food registrations within roughly a mile and a half of Well End. Booking early in the term gives the best choice of holiday dates.
What if parts of the system can’t be reached?
We record them on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
When should we have our next grease test?
Each report recommends when to test and clean next, based on the readings and how the kitchen is used. A risk assessment based on measured grease should set the interval.
How much time does an inspection need?
Typically, the inspection takes around an hour or two per canopy and duct system. The size of the system and the access make the difference.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What do the grease readings need to be?
The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. Our report sets your readings against both.
Part by part
Extract fan and discharge
Grease on the fan adds to wear. The inspection shows whether it needs cleaning now.
Restaurants, pubs and hotels
A kitchen running from breakfast to late service builds grease quickly. Regular testing shows whether the cleaning interval keeps up.
What we’re called out for in Well End
Not every section of a kitchen extract is easy to get to, so those sections can be skipped time and again. A survey finds the sections that can’t be reached, so panels can be fitted.
Any of these means the system needs a check-up:
- Kitchen extract systems with no recent grease readings
- Surveys needed before quoting a full clean
- Kitchens taken over with no cleaning records
- Heavy grease suspected in the plenum or ducts
Historic houses near Well End, such as Wyllyotts Manor about 3.3 miles north-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
What your quote should include
- What records you’ll receive afterwards
- If the quote is a fixed price or an estimate
- If they look at the system before pricing
- When the next visit should be, and why
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Flag changes in how much frying the kitchen does
- Store grease readings where your insurer can see them
- Flag oily drips near the extract
- Send TR19 audit reports to your insurer on request
After post-clean verification, file the results with the cleaning certificate. Together they show the system was cleaned and checked.
Fit access panels where the survey finds sections cannot be reached, so grease is not left building in hidden parts.
Grease, kitchens and Well End
Food Standards Agency records include about 12 bars, pubs and nightclubs and about 4 hotels and guest houses across Well End and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Food hygiene inspections in Well End are the job of Hertsmere council’s environmental health team. 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. Fire safety in Well End falls to Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
School kitchens, at schools like Hertswood Academy for example, are usually cleaned in the holidays so no lunches are lost. Healthcare kitchens, like those at hospitals such as Barnet General Hospital (about 2.2 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands.
