TR19 inspection in Vernham Street
BESA sets minimum cleaning intervals by daily use: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Those are minimums, and grease readings help set the real interval. The work covers insurer audits, access surveys and pre-clean surveys, and common reasons people get in touch are checking the result of a recent clean and pre-clean surveys before a first TR19 clean.
Somewhere as small as Vernham Street, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What we are called out for in Vernham Street
Grease in a duct is flammable 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.
Keep an eye out for these warning signs:
- Pre-clean surveys before a first TR19 clean
- Heavy grease suspected in the plenum or ducts
- Post-clean verification after another contractor’s clean
- Kitchens taken over with no cleaning records
Stargroves, about 4.2 miles north-east, is one of the historic houses near Vernham Street; if you run event catering at a venue like that, cleans can be booked between functions.
What your quote should include
- Whether the whole system is included, or only the parts that are easy to reach
- Whether a written report and photos are included
- If they look at the system before pricing
- When the next visit should be, and why
How the visit works
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 morning or less for one kitchen, more where there are several systems. Seeing the system in photos first means the trip to Vernham Street can be planned properly.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Let us know about parking and loading
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Getting a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
Part by part
Canopy and plenum
Filters can look fine while the plenum behind them is heavily coated. That’s why we test behind them.
Extract fan and discharge
The extract fan and its housing collect grease too. We check and test them as part of the inspection.
Aftercare tips
To keep the system working properly between visits:
- Diary the next grease test and clean
- Send TR19 audit reports to your insurer on request
- Keep canopy edges and gutters wiped down
- Keep TR19 certificates, readings and reports together
After post-clean verification, file the results with the cleaning certificate. Together they show the system was cleaned and checked.
Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.
What affects the cost of TR19 inspection
There’s no set price list, because no two systems are the same. The quote depends on:
- When the work can happen, such as evenings, overnight or weekends
- How many systems or sites are involved
- A single visit or a regular plan
- How big the system is
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- Photos showing the whole system and its surroundings
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or email us.
When it’s something else
In fairness, there are a few things this work won’t fix:
- Fire safety duties beyond the extract system
- Sections with no access, until panels are fitted
- Ductwork that was designed or installed badly
If you are not sure, just call 0345 646 2711, or email photos and we will give you a straight answer.
Parts of the system we cover

Grease, kitchens and Vernham Street
Kitchens in Vernham Street get their food hygiene inspections from Test Valley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. Vernham Street sits within the area of Hampshire and Isle of Wight 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.
Term dates shape school work: for a school like Vernham Dean Gillum's Church of England Primary School, an extract clean fits neatly into a half-term or summer break. Volunteers running a hall kitchen near Church of St Mary, or anywhere in Vernham Street, may not know when the extract was last cleaned, and a grease test settles it.
Vernham Street is about 7 miles north of Andover, in Hampshire. Every kind of commercial site in Vernham Street, we can take on TR19 inspection. Visits can be booked for evenings, overnight or weekends so trading is not interrupted. Vernham Street is one of 683 places in Hampshire we cover for commercial clients. There’s also a page for Reading, roughly 24 miles from Vernham Street.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
FAQs for Vernham Street
Can you get to a site in Vernham Street?
Yes. Vernham Street is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Who would carry out a food hygiene inspection at a kitchen in Vernham Street?
Kitchens in Vernham Street are inspected by Test Valley council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you look at the system first?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Is a quote from photos possible?
Yes, where the pictures show enough. If not, a site survey comes first, and the quote follows that.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What is grease thickness testing?
It’s a measurement of how much grease is coating the inside of the extract, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). The results are given in microns.
At what point does grease need cleaning?
TR19® Grease says grease should not go over a mean of 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
