TR19 inspections and grease testing in Thorley, Isle of Wight
TR19 inspection for commercial sites in Thorley and across the Isle of Wight. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Insurance renewals needing proof of TR19 cleaning
- Systems that need surveying before cleaning
- Post-clean verification after another contractor’s clean
When it’s something else
We’ll always give you a straight diagnosis, so here’s what TR19 inspection will not do:
- Removing the grease, which is a separate clean
- Ductwork that was designed or installed badly
- Hidden runs that need access panels first
If you are not sure, just call 0345 646 2711 or drop us a line and we’ll give you a straight answer before booking.
What we work on in Thorley
- Deposit thickness tests
- Access surveys
- Insurer audits
- Wet film thickness tests
- Post-clean checks
- Pre-clean surveys
How we handle TR19 inspection in Thorley
After a clean, post-clean verification checks the result, with fresh grease readings, pictures and a look at the areas that were cleaned. It shows whether the system was left in the condition the paperwork describes. If you are dealing with systems that need surveying before cleaning and parts of the system left out of past cleans, we can put it right, from access surveys, post-clean checks and wet film thickness tests onwards.
Somewhere as small as Thorley, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Your questions about TR19 inspection in Thorley
Which fire service covers Thorley?
Thorley is in the area of Hampshire and Isle of Wight Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can a school canteen extract in Thorley be done out of term time?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Thorley. You can call us on 0345 646 2711, or send details by email with the dates the site is empty.
Can you verify a clean after it’s been done?
Verification means repeat readings and photos once the clean is done. Any areas that weren’t cleaned properly are flagged.
Is Thorley in your area?
Yes. We work in Thorley and across the Isle of Wight, within our South East and London area. To book, phone us on 0345 646 2711 or send us an email.
How often should a kitchen extract be inspected?
It depends on how heavily the kitchen cooks. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and testing shows if your kitchen needs more.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Every site has its own report.
How much does TR19 inspection cost in Thorley?
Every site is different, so each gets its own fixed quote. For a quote, call us on 0345 646 2711, or email photos with the site type, opening hours and a few pictures.
What affects the quote in Thorley
We do not publish a price list, because sites vary so much. What we look at:
- Parking and loading at the site
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
- How big the system is
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before any work starts.
Helping us quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
We don’t publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, call us on 0345 646 2711, or send details by email.
When to call us in Thorley
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.
Keep an eye out for these warning signs:
- Insurers asking for TR19 evidence
- Checking the result of a recent clean
- Uncertainty over how often to clean
- Missing TR19 certificates or history
If you run catering at a historic house or estate in the area (Mottistone Manor is about 3.7 miles south-east), event kitchens in older buildings often have awkward duct runs that need planning.
What to look for in a quote
- Whether inaccessible sections are listed on the report
- Which accreditations they hold, and whether you can check them
- What insurance they carry
- If the quote is a fixed price or an estimate
Thorley kitchens: local notes
Thorley lies within about 2 miles of the sea. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. The FSA’s data shows about 6 bars, pubs and nightclubs and about 3 hotels, B&Bs and guest houses registered within roughly a mile and a half of the centre of Thorley. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Kitchens in Thorley get their food hygiene inspections from Isle of Wight council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
A hospital like Lymington New Forest Hospital, about 5.9 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Volunteers running a hall kitchen near St. Swithin's Church, or anywhere in Thorley, may not know when the extract was last cleaned, and a grease test settles it.
Thorley is about 5 miles south-east of Lymington, in the Isle of Wight. Sites in Thorley get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with pictures. Across the Isle of Wight, we cover 125 places, and Thorley is one of them. For sites nearby, see our Southampton page, about 16 miles away.
Work in PO41 follows the same survey, fixed quote and written report as everywhere else we cover. If your site is just outside Thorley, we cover Thorley Street (1 mile east), Wellow (1 mile south-east), Ningwood (2 miles east), Shalcombe (2 miles south-east) and Newbridge (2 miles east). Within a short drive, we also cover Newport (8 miles east), Ryde (14 miles east), Cowes (8 miles north-east), Sandown (14 miles east), Shanklin (14 miles east) and Ventnor (13 miles south-east). Remote and island sites need a little more planning, so tell us where you are when you ask for a quote for TR19 inspection.
Around Thorley
For rail, the closest station is Lymington Pier station, roughly 4.9 miles north-west of the centre. Well-known places in the area include Yarmouth Castle (1.4 miles north-west) and Ferguson Family Museum (1.7 miles west). Green spaces nearby include Lymington and Keyhaven Marshes Nature Reserve and Compton Down.
Why act early in Thorley
If a kitchen in Thorley has been cleaned on the same calendar for years, there’s no way to know if that interval is right without measuring. Measured readings let a competent person set the interval. Out of sight is the usual reason a rural system goes too long without attention.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.

What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
How the visit works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes a couple of hours for a typical kitchen extract system. A few pictures of the system help us make the most of a visit to a place like Thorley.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- We report the findings and flag any areas that need more work.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down
- Let us know when the site is closed or quiet
Get a fixed quote
Quoting starts with a diagnosis, either from photos 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 we start.

Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Diary the next grease test and clean
- Keep canopy edges and gutters wiped down
- Report grease dripping from the canopy
- Mention new equipment or longer hours at the next test
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can quote to do it.
Keep certificates, reports and readings in one place so you can produce them quickly.
