TR19 inspection in West Preston
A grease test measures how thick the grease is inside a kitchen extract system. 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. If you have extracts that have never been grease tested and post-clean verification after another contractor’s clean, we can put it right, from post-clean checks, pre-clean surveys and deposit thickness tests onwards.
In a smaller place like West Preston, many kitchens sit in older buildings or later 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.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Honest limits
We’ll always give you a straight diagnosis, so here’s what TR19 inspection will not do:
- The legal duty, which stays with the responsible person
- Heavy deposits found on test, which still need cleaning
- Sections with no access, until panels are fitted
If in doubt, ring 0345 646 2711 or drop us a line and we’ll say what we think.

Leave it or put it right?
Skipping grease testing leaves the cleaning interval to guesswork. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, which you won’t know without measuring. A visit arranged in advance is far less disruptive than a callout on a busy day.
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.

Fixed quotes for TR19 inspection in West Preston
We quote each job individually. This is what makes a difference:
- The condition we find in the survey
- One-off work versus a regular cycle
- How easy every part is to reach
- Site requirements such as sign-in and permits
What you pay depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.
Asking for a quote
What to send for a quote:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
- Any previous report or certificate
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.
Questions from West Preston
Can you get to a site in West Preston?
Yes, we work in villages as well as towns, and West Preston is covered. Let us know about access, parking and anything unusual about getting there when you book.
Can a school canteen extract in West Preston be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 18 schools and colleges with food registrations within roughly a mile and a half of West Preston. Tell us your holiday dates and we will book the visit for when the site is empty.
How much notice should we give?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Can you work evenings and weekends?
Yes. Give us your opening hours with your enquiry and we’ll book around them.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Do you check other contractors’ cleans?
A post-clean check records grease readings and photos after the work, for our cleans and other firms’ alike.
Do you look at the system first?
Yes. We always survey first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
What happens on a pre-clean survey?
We check the layout, the grease levels and the access, before anyone starts cleaning. Missing access panels are noted ahead of the clean.
Managing agents and facilities teams in West Preston
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Grease, kitchens and West Preston
Sea air reaches West Preston, which sits within about 1 mile of the coast. Salt air speeds up corrosion of roof-level fans, discharge cowls and their fixings. The FSA’s data shows about 16 bars, pubs and nightclubs and about 3 hotels and B&Bs registered within about 1.5 miles of central West Preston. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. West Preston is covered by West Sussex 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.
Term dates shape school work: for a school like Georgian Gardens Community Primary School, an extract clean fits neatly into a half-term or summer break. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Zachary Merton Hospital is the nearest hospital to West Preston, about within half a mile south-west.

When to call us in West Preston
Kitchens change: a new menu, longer hours or more frying can all add grease. A cleaning interval set years ago may no longer fit.
Clients usually contact us when they notice one of these:
- Extracts that may be over the 200 micron mean
- Confirming a clean reached the whole system
- Kitchens taken over with no cleaning records
- Sections of duct that cannot be reached
A hall kitchen that only cooks for events, whether near The Parish Church of St Mary or elsewhere in West Preston, still needs its extract cleaned, just less often.
What your quote should include
- Whether inaccessible sections are listed on the report
- Whether they’re fully insured
- If they look at the system before pricing
- What records you’ll receive afterwards
How it works
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, which takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. In a place like West Preston, we fit the visit around your hours.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Name a contact who can let us in at the agreed time
- Have your last certificate or report to hand
Get a fixed 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.

Part by part
Restaurants, pubs and hotels
Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, and readings show whether that’s enough.
Extract fan and discharge
A greasy fan works harder and wears faster. The inspection shows whether it needs cleaning now.
