For landlords and multi-site operators
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 can quote for the whole system.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
How we handle TR19 inspection in Owslebury
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). The results show whether the system needs cleaning and how soon. The work covers access surveys, deposit thickness tests and post-clean checks, and the jobs we see most are missing access panels found on survey and systems cleaned on a calendar with no measurements.
Work in a small place like Owslebury starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What affects the quote in Owslebury
The survey tells us what the work involves. The main factors are:
- How big the system is
- How many systems or sites are involved
- Site rules, permits and inductions
- The times the site is available
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
What we need to know
To help us quote quickly, please include:
- Any access panels or hatches you can see
- A few general shots of the system
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
Common problems we fix in Owslebury
As hot, greasy air travels up the duct, it cools and leaves a film behind. It often collects where nobody can see it: the plenum, bends and horizontal runs.
Most sites get in touch after spotting one of these:
- Kitchen extract systems with no recent grease readings
- Kitchens whose menu or hours have changed
- Surveys needed before quoting a full clean
- Post-clean verification after another contractor’s clean
If you look after a school kitchen, at a school such as Owslebury Primary School or anywhere near Owslebury, the holidays are the usual time for a TR19® clean.
Questions to ask before booking
- What paperwork you get at the end
- Whether they recommend a next date
- If they look at the system before pricing
- Proof of insurance
What happens if it’s left?
A pre-clean survey avoids surprises on the night. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, so the clean covers the whole system. Planning a trip to Owslebury ahead is easier for everyone than a rushed one.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

Between visits
So the system stays in good health:
- Flag oily drips near the extract
- Diary the next grease test and clean
- Clean grease off the canopy between professional cleans
- Never cook with filters missing
The audit report is set out to pass straight to your insurer or broker, including readings, photos and any inaccessible sections.
When cooking hours or the menu change, check the interval still fits. A quick grease test answers the question.
TR19 inspection around Owslebury
Owslebury sits within the area of Hampshire and Isle of Wight 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. Food hygiene inspections in Owslebury are the job of Winchester City council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
A hall kitchen that only cooks for events, whether near Church of St Andrew or elsewhere in Owslebury, still needs its extract cleaned, just less often. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Owslebury is St John's Rooms And Chapel, about 4 miles north-west.

Different parts, different methods
Restaurants, pubs and hotels
BESA’s minimum for heavy use of 12 to 16 hours a day is a clean every 3 months, and readings show whether that’s enough.
Canopy and plenum
The plenum behind the filters can carry a lot of grease. Readings and photos are taken in the plenum on every inspection.

Owslebury questions
Do you work in villages like Owslebury?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Who is the fire and rescue service for Owslebury?
Hampshire and Isle of Wight Fire and Rescue Service is the fire and rescue service for Owslebury. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
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 doesn’t spread.
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.
What information do you need?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply call us on 0345 646 2711 or drop us a line.
What does a pre-clean survey involve?
The survey covers the whole system, grease readings and access to each section. From it, we plan the clean and quote a fixed price.
Can you verify a clean after it’s been done?
Post-clean verification is a check after a clean, with fresh grease readings and pictures. It works whoever carried out the clean.
What if parts of the system cannot be reached?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a couple of hours for a typical kitchen extract system. A quick note on how to find the site and where to park makes a visit to Owslebury run smoothly.
- After the clean, we arrange a time to check the system.

- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
