What TR19 inspection can’t fix

Some problems need a different service or another trade:

  • Design faults in the extract system
  • Parts of the duct nobody can reach yet
  • The legal duty, which stays with the responsible person

TR19 inspection in Dunsbury, done properly

A pre-clean survey is the diagnosis, and the clean is the treatment. We look at the system, take grease readings and photograph what we find, so the clean can be planned properly. Common call-outs are for confirming a clean reached the whole system and insurers asking for TR19 evidence, on insurer audits, pre-clean surveys and wet film thickness tests.

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.

Nothing is signed off by word of mouth: a dated report with photos 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.

What happens on the day

There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes an hour or two for a single kitchen, longer for a large or complex system. For a village or hamlet like Dunsbury, tell us about narrow lanes, gates and parking when you book.

  1. We go through any past certificates and reports.
  2. We follow the extract from canopy to discharge.
  3. Access panels are located and any missing ones noted.
  4. Grease readings are taken and pictures recorded.
  5. We report back with readings and a fixed quote.

Before we arrive

  • Mention any sign-in, permit or induction we need
  • Tell us the best time to work, such as after service or at a weekend
  • Have your last certificate or report to hand

Getting a quote

To get a fixed quote, give us a ring on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You’ll typically have a quote within one working day.

Dunsbury questions

Do you work overnight in Dunsbury?

Yes, evening, overnight and weekend work is normal for us. The work in Dunsbury can fit around your hours. Tell us your opening hours when you ask for a quote.

Is Dunsbury within the area you cover?

Yes. Dunsbury is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

How much does TR19 inspection cost?

There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.

What happens if you cannot reach some of it?

Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.

What information do you need?

Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply call 0345 646 2711, or send details by email.

Can we book visits on a schedule?

Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.

What is post-clean verification?

Verification means repeat readings and pictures once the clean is done. Any areas that weren’t cleaned properly are flagged.

What grease levels does TR19 allow?

Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. 500 microns or more at any point calls for immediate spot cleaning.

What TR19 inspection looks like in Dunsbury

At about 1 mile from the coast, Dunsbury is close enough for sea air to matter. Corrosion on the fan housing and cowl is worth a look at every clean, alongside the grease. It’s Isle of Wight council that sends environmental health officers to food businesses in Dunsbury. 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. Dunsbury 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.

A hall kitchen that only cooks for events, whether near St. Mary's Church or elsewhere in Dunsbury, still needs its extract cleaned, just less often.

In-house cleaning or a specialist?

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.

A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

How the job changes from site to site

Horizontal duct runs

Bends and long runs can hold heavy deposits, well away from where anyone looks.

Extract fan and discharge

The extract fan and its housing collect grease too. We check and test them as part of the inspection.

When to call us in Dunsbury

Grease builds up as cooking vapour cools inside the extract. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.

Any of these means the system needs a check-up:

  • Kitchens taken over with no cleaning records
  • Systems that need surveying before cleaning
  • Parts of the system left out of past cleans
  • Extracts that have never been grease tested

Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Mottistone Manor is about 1.2 miles east), access may need planning.

Questions to ask before you book

For landlords and multi-site operators

Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.

What affects the cost of TR19 inspection

We quote each job individually. These are the things that affect it:

  • Whether we need access equipment or extra panels
  • A single visit or a regular plan
  • The condition of the system
  • Working hours and out-of-hours timing

The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before work begins.

What we need to know

We can often survey from photos. The most useful are:

  • The site address and the type of premises
  • Problems your staff have spotted
  • Wide pictures of the system and the area around it
  • Your opening hours and when the area is out of use

Want a quote for TR19 inspection? Please give us a ring on 0345 646 2711, or email photos with a few details about the site. We will explain what we’d do and send a fixed quote before you commit to anything.
