How we handle TR19 inspection in Thornhill
Post-clean verification is a check carried out once the cleaning is done, with new readings and pictures of the cleaned areas. It gives you evidence of how the system was actually left. Common call-outs are for sections of duct that can’t be reached and insurers asking for TR19 evidence, on pre-clean surveys, wet film thickness tests and post-clean checks.
In a smaller place like Thornhill, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

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 anything from an hour for a small canopy and short duct to a good part of a day for a large site. In a place like Thornhill, we fit the visit around your hours.
- The visit is arranged for when the kitchen isn’t busy.
- The system is checked from canopy to discharge.
- We take WFTT or DTT readings at set points along the system.
- Photos are taken at each point, and access gaps noted.
- We send a report setting out the readings, pictures and next steps.
Before we arrive
- Name a contact who can let us in at the agreed time
- Plan for cooking equipment or plant to be off before we arrive
- Tell us where we can park and unload

In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Common problems we fix in Thornhill
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. The old cleaning schedule may not match the kitchen any more.
It’s time to book a visit if you see:
- Extracts that may be over the 200 micron mean
- Insurance renewals needing proof of TR19 cleaning
- Missing TR19 certificates or history
- Pre-clean surveys before a first TR19 clean
Healthcare kitchens, like those at hospitals such as Moorgreen Hospital (about 1.4 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Your questions about TR19 inspection in Thornhill
Can sea air affect TR19 inspection in Thornhill?
It can, as Thornhill is within about 3 miles of the sea, where salt in the air is hard on metal. We look at fans, cowls and fixings for rust as well as grease.
Will you come out to Thornhill?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
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 ahead of the clean.
Can the work be done while we’re closed?
Yes. Evenings, nights and weekends are normal working hours for us, so the site does not lose a service.
How do you protect the area?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. At the end, the area is cleaned down.
How much notice should we give?
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.
How do you measure grease in a kitchen extract?
WFTT and DTT are the two methods for measuring grease thickness, in microns. Readings are taken at set points through the system.
When something else is needed
TR19 inspection can’t fix everything, and we will tell you before we start. It will not put right:
- Fire safety duties beyond the extract system
- Installation problems, which fall under design guidance such as DW172
- Heavy deposits found on test, which still need cleaning
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we will tell you honestly.
Where we work
- Deposit thickness tests
- Wet film thickness tests
- Post-clean checks
- Pre-clean surveys
- Insurer audits
- Access surveys
What happens if it’s left?
If there’s a fire or a claim, your insurer may ask for TR19 records. Missing records can put a claim at risk. An up-to-date inspection report is a good place to start. A planned visit to Thornhill fits your hours; an emergency does not.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

Thornhill kitchens: local notes
Sea air reaches Thornhill, which sits within about 3 miles of the coast. Near the sea, the fan and discharge at the top of a kitchen extract corrode faster than they would inland. Look up Thornhill on the FSA’s food hygiene register and you’ll find about 32 restaurants, cafés and works canteens and about 41 takeaways in and around Thornhill, up to about a mile and a half out. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Food hygiene inspections in Thornhill are the job of Southampton council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (South Stoneham House is about 2.4 miles north-west), access may need planning. Bursars and site managers at schools such as Thornhill Primary School tend to book extract cleaning for when the kitchen is empty.
