When it’s something else
We’ll always give you a straight diagnosis, so here’s what TR19 inspection won’t do:
- Fan breakdowns, which need a repair visit
- Sections with no access, until panels are fitted
- Removing the grease, which is a separate clean
If in doubt, call us on 0345 646 2711 or drop us a line and we will say what we think.
Where we work
- Insurer audits
- Wet film thickness tests
- Pre-clean surveys

About our TR19 inspection in Milton
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. From the numbers, you can see whether cleaning is due. If you have kitchen extract systems with no recent grease readings and missing access panels found on survey, we can put it right, from wet film thickness tests, insurer audits and post-clean checks onwards.
Kitchens around a place like Milton are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
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 and sits alongside the report.

What affects the cost of TR19 inspection
The survey tells us what the work involves. The main factors are:
- How big the system is
- Parking and loading at the site
- What state the system is in
- Site rules, permits and inductions
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
What we need to know
We can often survey from pictures. The most useful are:
- The site address and the type of premises
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- Your last certificate, test record or report
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes an hour or two for a single kitchen, longer for a large or complex system. Everything the job in Milton needs is worked out beforehand, from the survey.
- We agree a time when the kitchen is closed or quiet.
- We look over the canopy, plenum, ducts, fan and discharge.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- We send a report setting out the readings, photos and next steps.
Getting ready for the visit
- Clear the space around the work
- Let us know about parking and loading
- Tell us about site rules, permits or sign-in

What we’re called out for in Milton
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and grease in the extract is part of that risk.
Signs it’s time to call us include:
- Cleaning intervals that may not suit the kitchen
- Checking the result of a recent clean
- Ductwork where grease may be over the TR19 limits
- Insurers asking for TR19 evidence
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Milton is St. Mary's Hospital, about under half a mile north-west.
Before you book anyone
- Proof of insurance
- Whether the whole system is included, or only the parts that are easy to reach
- Whether inaccessible sections are listed on the report
- Whether the price is fixed
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.
Facilities teams in offices, schools and healthcare sites book us too across Portsmouth. Larger estates can be phased building by building around the people who use them.
Your questions about TR19 inspection in Milton
Do you cover smaller places like Milton?
Yes, we work in villages as well as towns, and Milton is covered. Let us know about access, parking and anything unusual about getting there when you book.
Which council inspects kitchens in Milton?
The local authority for Milton is Portsmouth council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
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.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Can you quote from photos?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Kitchen extracts in Milton
At about 1 mile from the coast, Milton is close enough for sea air to matter. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. Food Standards Agency records include about 69 pubs, bars and clubs and about 13 hotels and B&Bs within 1.5 miles or so of the middle of Milton. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Environmental health officers from Portsmouth council inspect food businesses in Milton. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Where a hall near Church of St James, or anywhere in Milton, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Commuter trade near Fratton station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
