How we handle TR19 inspection in Otterbourne

After a clean, post-clean verification checks the result, with fresh grease readings, photos and a look at the areas that were cleaned. It gives you evidence of how the system was actually left. The work covers pre-clean surveys, wet film thickness tests and deposit thickness tests, and the jobs we see most are cleaning intervals that may not suit the kitchen and sites with gaps in their extract records.

Somewhere as small as Otterbourne, 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.

The sign-off is always in writing: a dated report with photos of the work, 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.

Keeping the system healthy

To keep the system working properly between visits:

  • Clean grease off the canopy between professional cleans
  • Look out for grease drips round the canopy edge
  • Tell us if menus or opening hours change
  • Have the latest report ready for insurance renewals

For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.

Keep all TR19 records together so you can produce them quickly.

In-house cleaning or a specialist?

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.

If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.

What TR19 inspection looks like in Otterbourne

The FSA’s data shows about 6 pubs, bars and clubs registered within 1.5 miles or so of the middle of Otterbourne. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Otterbourne is covered by 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. Kitchens in Otterbourne get their food hygiene inspections from Winchester City council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.

If you run a church or community hall kitchen, near Church of St Matthew or elsewhere in Otterbourne, its extract still collects grease from every lunch and event. Bursars and site managers at schools such as Otterbourne Church of England Primary School tend to book extract cleaning for when the kitchen is empty.

What we are called out for in Otterbourne

As hot, greasy air travels up the duct, it cools and leaves a film behind. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.

These are the problems we see most often:

  • Uncertainty over how often to clean
  • Insurers asking for TR19 evidence
  • Extracts that have never been grease tested
  • Parts of the system left out of past cleans

If you run catering at a healthcare site, such as a hospital like Royal Hampshire County Hospital about 3.7 miles north, the extract may need cleaning more often than a part-time kitchen.

Choosing a duct cleaning contractor

The process

When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes around an hour or two per canopy and duct system. For a village or hamlet like Otterbourne, tell us about narrow lanes, gates and parking when you book.

  1. We agree a time when the kitchen is closed or quiet.
  2. We look over the canopy, plenum, ducts, fan and discharge.
  3. We take WFTT or DTT readings at set points along the system.
  4. Each test point and any access problems are photographed.
  5. The findings go into a report with readings, pictures and a recommended next clean.

Preparing for the visit

  • Have your last certificate or report to hand
  • Agree a time when the area can be out of use
  • Make sure equipment near the work can be switched off and left to cool

Ask for a quote

Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before work begins.

When it’s something else

An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection will not do:

  • Removing the grease, which is a separate clean
  • Hidden runs that need access panels first
  • The legal duty, which stays with the responsible person

If in doubt, give us a ring on 0345 646 2711, or email photos and we will say what we think.

Parts of the system we cover

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

Questions from Otterbourne

Is Otterbourne within the area you cover?

Yes, Otterbourne is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.

Can a school canteen extract in Otterbourne be done out of term time?

Yes. Half-terms and the summer break are the natural time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Otterbourne, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.

What is TR19?

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.

Can you look after several sites?

Yes. One number covers all your sites in our area, with visits on a regular schedule.

What is grease thickness testing?

It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. Each reading is recorded in microns.

What do you need from me for a quote?

Some pictures and a quick description of the system plus the address and your hours. If we need more, we’ll ask.

Can you price the work without visiting?

Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.

Why survey before a clean?

The survey covers the whole system, grease readings and access to each section. From it, we plan the clean and quote a fixed price.

How we price TR19 inspection

The quote reflects the site in front of us. We consider:

  • The condition of the system
  • Parking and loading at the site
  • How easy every part is to reach
  • How many systems or sites are involved

One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.

Helping us quote

When you call or email, it’s useful to have:

  • The site address and the type of premises
  • Wide photos of the system and the area around it
  • When the site is open and when it’s quiet
  • Close-ups of filters, grilles, hatches or access panels

Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
