TR19 inspection in St Denys, done properly
Post-clean verification is a check carried out once the cleaning is done, with fresh grease readings, photos and a look at the areas that were cleaned. It gives you evidence of how the system was actually left. If you are dealing with extracts that may be over the 200 micron mean and insurance renewals needing proof of TR19 cleaning, we can help.
In a smaller place like St Denys, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How the visit works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes anything from an hour for a small canopy and short duct to a good part of a day for a large site, and the area is cleaned down before we leave. Around St Denys, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.
- The visit is arranged for when the kitchen isn’t busy.
- Every part of the system is examined, end to end.
- Grease readings are taken at set points using WFTT or DTT.
- Each test point and any access problems are photographed.
- You get a report with readings, photos and recommendations.
Before we arrive
- Agree a time when the area can be out of use
- Name a contact who can let us in at the agreed time
- Move anything stored near the system

FAQs for St Denys
Which fire authority looks after St Denys?
It’s Hampshire and Isle of Wight Fire and Rescue Service, which covers St Denys. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can sea air affect TR19 inspection in St Denys?
It can, as St Denys is within about 2 miles of the sea, where salt in the air is hard on metal. Rooftop fans, discharge cowls and fixings are checked for corrosion as well as grease.
Is TR19 cleaning the law?
No, TR19® isn’t legislation. But the responsible person must assess and reduce fire risk under the Fire Safety Order 2005, which in a kitchen includes grease in the extract. Many insurers also expect TR19 cleaning.
Do you work out of hours?
Yes. Much of our work happens in the evening, overnight or at weekends, so the site doesn’t lose a service.
What is a WFTT or DTT grease test?
The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. We take readings at set points from canopy to fan.
Do you carry out TR19 audits for insurers?
Yes. Insurers often want evidence the extract is managed to TR19®, and our audit gives a clear record of the system’s condition, along with any actions needed.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
When should we have our next grease test?
Often enough to know the mean stays under 200 microns between cleans. If readings rise, the interval should shorten.
When something else is needed
We will not sell you work that doesn’t address the problem, so here are the limits:
- Mechanical faults in the extract
- Hidden runs that need access panels first
- Removing the grease, which is a separate clean
If you are not sure, just phone us on 0345 646 2711 or send us an email and we will give you a straight answer.

What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
What TR19 inspection looks like in St Denys
St Denys lies within about 2 miles of the sea. Near the sea, the fan and discharge at the top of a kitchen extract corrode faster than they would inland. There are about 208 restaurants, cafés and canteens and about 110 takeaways in St Denys and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. For any of them with a canopy, measuring grease is better than guessing when to clean. Environmental health officers from Southampton council inspect food businesses in St Denys. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Where a hall near Church of St Denys, or anywhere in St Denys, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Bursars and site managers at schools such as St Denys Primary School tend to book extract cleaning for when the kitchen is empty. For kitchens close to St Denys station, where the day often starts early and ends late, the extract can be cleaned overnight.

Aftercare tips
Think of this as the after-treatment advice, in brief:
- Report grease dripping from the canopy
- Keep TR19 certificates, readings and reports together
- Keep grease filters clean and fitted properly
- Keep the route to access panels clear
For an insurer audit, send them the report as it is, with readings, photos and any areas not accessible.
Close the access gaps found during inspection, so every part of the duct can be cleaned.
