One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before we start.

TR19 inspection in Colliers Green, done properly

Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. From the numbers, you can see whether cleaning is due. The work covers insurer audits, post-clean checks and deposit thickness tests, and the jobs we see most are ductwork where grease may be over the TR19 limits and kitchens whose menu or hours have changed.

In a village or hamlet like Colliers Green, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.

The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Looking after it afterwards

Simple habits between visits make a real difference. We recommend:

  • Tell us if menus or opening hours change
  • Report grease dripping from the canopy
  • Store grease readings where your insurer can see them
  • Wipe the canopy surfaces regularly

Each report suggests the next clean and the next test, from the measured grease and the kitchen’s hours.

Fit access panels where the survey finds sections cannot be reached, so every part of the duct can be cleaned.

Do you need TR19 inspection in Colliers Green?

Looking at a canopy tells you little about what’s in the duct. Clean filters can hide a heavy layer behind them, which is why readings matter.

The symptoms we’re asked about most are:

  • Pre-clean surveys before a first TR19 clean
  • Kitchen extract systems with no recent grease readings
  • Insurers asking for TR19 evidence
  • Parts of the system left out of past cleans

Term dates shape school work: for a school like Colliers Green Church of England Primary School, an extract clean fits neatly into a half-term or summer break.

Before booking anyone

Questions to ask before you book

What staff can safely do

Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow 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: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.

Kitchen extracts in Colliers Green

Environmental health officers from Tunbridge Wells council inspect food businesses in Colliers Green. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Colliers Green is about 37 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.

What TR19 inspection can’t fix

We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:

  • Parts of the duct nobody can reach yet
  • Fire safety duties beyond the extract system
  • Fan breakdowns, which need a repair visit

Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we’ll tell you honestly before booking.

What the work covers

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

What happens on the day

We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. The work itself takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. If the van will struggle with a lane or gateway near Colliers Green, let us know and we will plan around it.

  1. Post-clean verification is booked once the clean is done.
  2. The same access points are opened up.
  3. We repeat the WFTT or DTT readings.
  4. Photos are taken to show the condition after the clean.
  5. We report the findings and flag any areas that need more work.
