Hampshire · TR19 inspections and grease testing
Clayhall TR19 inspection
TR19 inspection in Clayhall from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Kitchen extract systems with no recent grease readings
- Checking the result of a recent clean
- Cleaning intervals that may not suit the kitchen
TR19 inspection in Clayhall, done properly
A fixed schedule does not always match how a kitchen really cooks. In a busy kitchen, grease can build faster than the minimum intervals allow for, and only measurement shows it. We give your risk assessment measured figures rather than guesses. The work covers post-clean checks, wet film thickness tests and deposit thickness tests, and common reasons people get in touch are checking the result of a recent clean and extracts that may be over the 200 micron mean.
Around a smaller place like Clayhall, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What we’re called out for in Clayhall
Looking at a canopy tells you little about what’s in the duct. A system can look clean at the filters and be heavily coated further in, so readings are the reliable guide.
Any of these means the system needs a check-up:
- Heavy grease suspected in the plenum or ducts
- Systems that need surveying before cleaning
- Confirming a clean reached the whole system
- Parts of the system left out of past cleans
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Gosport War Memorial Hospital is the nearest hospital to Clayhall, about 1 mile north-west.
What to look for in a quote
- Whether a survey comes first
- If the quote is a fixed price or an estimate
- Whether inaccessible sections are listed on the report
- Whether the whole system is included, or only the parts that are easy to reach
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection won’t do:
- Mechanical faults in the extract
- Heavy deposits found on test, which still need cleaning
- Hidden runs that need access panels first
If you’re not sure, just ring 0345 646 2711 or drop us a line and we will give you a straight answer before you book.
Parts of the system we cover
- Deposit thickness tests
- Wet film thickness tests

What we do, step by step
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes around an hour or two per canopy and duct system. In a smaller place like Clayhall, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
Getting ready for the visit
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend
- Mention any locked doors, roof access or ceiling voids
Getting a quote
To get a fixed quote, ring 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
Advice
Why deal with it now?
A pre-clean survey avoids surprises on the night. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, and the quote reflects the real job. Booking now means the visit to Clayhall is planned around you, not forced by a breakdown.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before any work starts.

TR19 inspection around Clayhall
Clayhall lies within about 1 mile of the sea. Salt air speeds up corrosion of roof-level fans, discharge cowls and their fixings. There are about 64 cafés, restaurants and staff canteens and about 24 takeaways across Clayhall and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. For any of them with a canopy, measuring grease is better than guessing when to clean. Fire safety in Clayhall falls to 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.
For schools such as Haselworth Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Church and community hall kitchens, near St Francis or anywhere around Clayhall, are easy to forget, but their extracts collect grease like any other.

FAQs for Clayhall
Who enforces fire safety at workplaces in Clayhall?
Hampshire and Isle of Wight Fire and Rescue Service is the fire and rescue service for Clayhall. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Which environmental health team covers Clayhall?
Kitchens in Clayhall are inspected by Gosport council’s environmental health officers. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
What do the grease readings need to be?
The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. We show your readings against those figures.
What should I send you?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we are fully insured.
What the work involves, part by part
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. They’re included in the readings and pictures.
Restaurants, pubs and hotels
Inspections are done when the kitchen is closed or quiet so the kitchen keeps cooking.
What affects the cost of TR19 inspection
The diagnosis comes before the price. The main factors are:
- The times the site is available
- A single visit or a regular plan
- Parking and loading at the site
- The size of the system
The cost depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Detail shots of panels, filters and grilles
- The paperwork from the last visit, if you have it
To help us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or send us an email.
What your team can do, and what needs us
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, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
