TR19 inspection near Underriver

TR19 inspection in Underriver

Insurance policies often require evidence of TR19® cleaning and inspection. Without it, a claim can be refused or reduced. A TR19 audit sets out the system’s condition, with readings and pictures, for sites in Underriver and the rest of Kent. Typical jobs include uncertainty over how often to clean and surveys needed before quoting a full clean, on deposit thickness tests, pre-clean surveys and post-clean checks.

In a small place like Underriver, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.

For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Landlords, agents and facilities managers

Facilities teams in offices, schools and healthcare sites book us too in Underriver and across Kent. Larger estates can be phased building by building around the people who use them.

Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.

Do you need TR19 inspection in Underriver?

TR19® is the benchmark that insurers, fire officers and EHOs refer to. It isn’t legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and grease in the extract is part of that risk.

What we’re most often called out for:

  • Sites with gaps in their extract records
  • Sections of duct that cannot be reached
  • Uncertainty over how often to clean
  • Surveys needed before quoting a full clean

Volunteers running a hall kitchen near Church of St Margaret, or anywhere in Underriver, may not know when the extract was last cleaned, and a grease test settles it.

Questions to ask before booking

  • Whether the price is fixed
  • What paperwork you get at the end
  • What’s included in the scope, part by part
  • Whether they recommend a next date

Questions to ask before you book

Staff cleaning versus specialist work

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.

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

Honest limits

It’s worth knowing the limits before booking:

  • Hidden runs that need access panels first
  • Design faults in the extract system
  • Removing the grease, which is a separate clean

If you are not sure, just call us on 0345 646 2711 or drop us a line and we will give you a straight answer.

Where we work

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

What the work involves, part by part

Vertical risers

Vertical risers take the extract up through the floors. Grease can drain down and pool at the bottom, so the base is a key test point.

Canopy and plenum

The canopy itself is checked inside and out, with readings where grease collects.

How the visit works

When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes a morning or less for one kitchen, more where there are several systems. If you can send pictures, we can arrive in Underriver knowing what to expect.

  1. We go through any past certificates and reports.
  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.

Before we arrive

  • Mention any sign-in, permit or induction we need
  • Let us know about parking and loading
  • Allow time for equipment near the work to be turned off and cool down

Ask for a quote

To get a fixed quote, give us a ring on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.

TR19 inspection in Underriver: the local picture

There are about 6 cafés, restaurants and staff canteens within 1.5 miles or so of the middle of Underriver, according to the Food Standards Agency’s register. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. It’s Sevenoaks council that sends environmental health officers to food businesses in Underriver. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Underriver sits within the area of Kent 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.

If your kitchen is in a listed or historic building, like the houses around Underriver (Knole House is about 1.6 miles north-west), fitting access panels needs care.
