TR19 inspection in Thrupp, done properly

Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). From the numbers, you can see whether cleaning is due. If you have kitchens whose menu or hours have changed and missing TR19 certificates or history, we can put it right.

Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.

The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Different parts, different methods

Extract fan and discharge

A greasy fan works harder and wears faster. Readings show if it needs attention before the next clean.

Horizontal duct runs

Grease settles on the floor of horizontal ducts as the air cools. Readings are taken along each run through its access panels.

What a clean won’t put right

Not every problem is solved by TR19 inspection, and we’d rather say so up front. It will not put right:

  • Sections with no access, until panels are fitted
  • Mechanical faults in the extract
  • Ductwork that was designed or installed badly

If in doubt, call 0345 646 2711, or send details by email and we’ll say what we think.

Where we work

  • Insurer audits
  • Access surveys
  • Pre-clean surveys
  • Deposit thickness tests
  • Post-clean checks
  • Wet film thickness tests

Common questions in Thrupp

Can you work in Thrupp outside opening hours?

Yes, nights and weekends are routine for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.

Which fire authority looks after Thrupp?

That is Oxfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Do you offer maintenance contracts?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.

Can you verify a clean after it’s been done?

A post-clean check records grease readings and photos after the work, whoever did the clean.

How do you protect the area?

Floors and surfaces near the work are sheeted before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.

What information do you need?

Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply give us a ring on 0345 646 2711 or email us.

Are you accredited?

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.

Do you look at the system first?

Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.

What happens if it’s left?

Surveying first means the clean goes to plan. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, so the clean covers the whole system. In a small place like Thrupp, a system that fails can take a site out of use.

No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

Thrupp kitchens: local notes

The FSA’s data shows about 3 pubs, bars and clubs registered in and around Thrupp, up to about a mile and a half out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. It’s Cherwell council that sends environmental health officers to food businesses in Thrupp. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Thrupp falls to Oxfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.

School kitchens, at schools like The Marlborough Church of England School for example, are typically cleaned in the holidays so no lunches are lost. If you run a church or community hall kitchen, near Church of Holy Cross or elsewhere in Thrupp, its extract still collects grease from every lunch and event. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Thrupp is Acland Hospital, about 5.7 miles south.

The process

Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a couple of hours for a typical kitchen extract system, and we clear up before we go. Pictures of the system and its access let us plan the work in Thrupp before we set off.

  1. We agree a time when the kitchen is closed or quiet.
  2. We look over the canopy, plenum, ducts, fan and discharge.
  3. Grease thickness is measured at set points by WFTT or DTT.
  4. Photos are taken at each point, and access gaps noted.
  5. We send a report setting out the readings, pictures and next steps.

Before we arrive

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Have your last certificate or report to hand
  • Tell us about site rules, permits or sign-in

Staff cleaning versus specialist work

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’s our job.

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Keeping the system healthy

Good habits slow the build-up between visits. Our tips:

  • Keep grease filters clean and fitted properly
  • Flag oily drips near the extract
  • File every inspection report with your certificates
  • Flag changes in how much frying the kitchen does

Any access problems we found are listed with a suggested fix. With panels fitted, the next clean can cover every section.

Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.

What affects the quote in Thrupp

There’s no set price list, because no two systems are the same. What we look at:

  • Where the site is and how we reach it
  • A single visit or a regular plan
  • Whether we need access equipment or extra panels
  • How big the system is

The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.

Asking for a quote

To help us quote quickly, send us:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • The postcode and the type of business
  • Your last certificate, test record or report
  • Any access panels or hatches you can see

Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
