About our TR19 inspection in Bishopstone

Not every kitchen fits neatly into a calendar. 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, deposit thickness tests and access surveys, and common reasons people get in touch are uncertainty over how often to clean and heavy grease suspected in the plenum or ducts.

Somewhere as small as Bishopstone, 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, whatever the size of the place.

The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What TR19 inspection can’t fix

Some problems need a different service or another trade:

  • The grease itself, which needs a full or spot clean
  • The responsible person’s own fire risk assessment
  • Sections with no access, until panels are fitted

Not sure which it is? You can call us on 0345 646 2711, or send details by email and we will tell you honestly.

Parts of the system we cover

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

Signs you need TR19 inspection in Bishopstone

Some parts of a system are hard to reach, so those sections can be skipped time and again. A survey finds the sections that cannot be reached, so the gaps can be closed.

These are the problems we see most often:

  • Heavy grease suspected in the plenum or ducts
  • Systems cleaned on a calendar with no measurements
  • Uncertainty over how often to clean
  • Missing access panels found on survey

Bursars and site managers at schools such as The Mandeville School tend to book extract cleaning for when the kitchen is empty.

What your quote should include

  • What insurance they carry
  • Whether the work can be done while the site is closed
  • When the next visit should be, and why
  • What happens if part of the system cannot be accessed

Questions to ask before booking

Part by part

Horizontal duct runs

Flat duct runs collect grease along their base. Readings are taken along each run through its access panels.

Canopy and plenum

We look over the canopy, inside and out, and note where grease has gathered.

In-house cleaning or a specialist?

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.

Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.

Bishopstone: your questions answered

Which fire authority looks after Bishopstone?

Buckinghamshire Fire and Rescue Service is the fire and rescue service for Bishopstone. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

Will you come out to Bishopstone?

Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.

Do you have a 24/7 line?

Yes. Our emergency line runs 24/7, for problems that can’t wait. Ring any time and tell us what’s happened.

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

Post-clean verification is a check after a clean, with fresh grease readings and pictures. It works whoever carried out the clean.

How do you measure grease in a kitchen extract?

We measure the grease at set points with a WFTT or DTT test, then compare them with the TR19® Grease figures.

Can you price the work without visiting?

Often, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.

Which kinds of sites do you work on?

All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.

Is there a survey before the work?

Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.

What we do, step by step

We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes around an hour or two per canopy and duct system. In a small place like Bishopstone, the journey is planned ahead and the visit arranged around the site’s hours.

  1. First we look at the system’s cleaning history, if there is one.
  2. We follow the extract from canopy to discharge.
  3. We note where access panels are and where more are needed.
  4. Grease readings are taken and pictures recorded.
  5. You get a report and a fixed quote for the clean.

How to prepare

Related advice

Between visits

Aftercare is simple, and it makes the next visit easier:

  • Report grease dripping from the canopy
  • Send TR19 audit reports to your insurer on request
  • Keep canopy edges and gutters wiped down
  • File every inspection report with your certificates

Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can arrange it.

Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.
