About our TR19 inspection in Stonymarsh
Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. The results show whether the system needs cleaning and how soon. The work covers access surveys, post-clean checks and wet film thickness tests, and people most often call us about extracts that have never been grease tested and parts of the system left out of past cleans.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
The paperwork matters as much as the work. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Part by part
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 is enough.
Extract fan and discharge
Grease on the fan adds to wear. Readings show if it needs attention before the next clean.

Why deal with it now?
Sites in Stonymarsh that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Testing gives you the evidence to set it properly. Systems in rural buildings are often out of sight and out of mind.
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.

When to call us in Stonymarsh
TR19® is the benchmark that insurers, fire officers and EHOs refer to. It isn’t legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and grease in the extract is part of that risk.
Look out for any of the following:
- Heavy grease suspected in the plenum or ducts
- Uncertainty over how often to clean
- Systems that need surveying before cleaning
- Checking the result of a recent clean
A hall kitchen that only cooks for events, whether near Church of St Andrew or elsewhere in Stonymarsh, still needs its extract cleaned, just less often.
Before you book anyone
- What insurance they carry
- Whether VAT is included
- Whether the price is fixed
- How they set the interval to the next visit
What affects the quote in Stonymarsh
A fixed price needs a few facts first. We check:
- The condition of the system
- How easy every part is to reach
- Whether several sites go on one quote
- Parking and loading at the site
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 are unsure, call 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
- Wide photos of the system and the area around it
- Your last certificate, test record or report

What a clean will not put right
To be straight with you, there are a few things this work will not fix:
- Installation problems, which fall under design guidance such as DW172
- Hidden runs that need access panels first
- The legal duty, which stays with the responsible person
If in doubt, give us a ring on 0345 646 2711 or email us and we’ll say what we think before you book.

TR19 inspection around Stonymarsh
Food Standards Agency records list about 4 cafés, restaurants and staff canteens within 1.5 miles or so of the middle of Stonymarsh. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Kitchens in Stonymarsh get their food hygiene inspections from Test Valley council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Stonymarsh sits within the area of Hampshire and Isle of Wight Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you run catering at a historic house or estate in the area (Mottisfont Abbey is about 0.5 miles west), event kitchens in older buildings often have awkward duct runs that need planning. If you run catering at a healthcare site, such as a hospital like Romsey Community Hospital about 3.7 miles south-east, the extract may need cleaning more often than a part-time kitchen.

Your questions about TR19 inspection in Stonymarsh
Can you come to Stonymarsh after we close?
Yes, we can come after you close and finish before you open. The work in Stonymarsh can fit around your hours. Your opening times are the first thing we ask for.
Do you work in villages like Stonymarsh?
Yes, we work in villages as well as towns, and Stonymarsh is covered. Just mention lanes, gates or anything else about the site when you book.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Ring any time and tell us what’s happened.
How much does TR19 inspection cost in Stonymarsh?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before any work starts.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Can you quote from photos?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What do you do with what you remove?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
How it works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, which takes a couple of hours for a typical kitchen extract system. Visits to a village like Stonymarsh are booked in advance, at a time that suits whoever runs the site.
- 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.
- Photos are taken at each point, and access gaps noted.
- We send a report setting out the readings, photos and next steps.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
How to get a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.
