TR19 inspection across Ash Green

TR19 inspection in Ash Green, done properly

Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Ash Green and across Surrey a clear record of the system’s condition. Typical jobs include systems that need surveying before cleaning and extracts that may be over the 200 micron mean, on deposit thickness tests, wet film thickness tests and pre-clean surveys.

For a kitchen in or near Ash Green, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.

It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Why deal with it now?

Sites in Ash Green that have never measured grease cannot tell whether their cleaning interval suits the kitchen. Testing gives you the evidence to set it properly. Out of sight is the usual reason a rural system goes too long without attention.

What you pay depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.

  • Fixed quotes, typically within one working day
  • Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease
  • Survey first, then a fixed quote
  • Accredited under CHAS and SafeContractor, with ISO 9001

What we are called out for in Ash Green

When a site in Ash Green changes owner or cleaning contractor, the records do not always follow. With no history, the current state of the extract is a guess.

If you notice any of these, it’s worth a diagnosis:

  • Ductwork where grease may be over the TR19 limits
  • Post-clean verification after another contractor’s clean
  • An insurer’s request for a TR19 audit
  • Systems that need surveying before cleaning

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

What to look for in a quote

  • What happens if part of the system cannot be accessed
  • Proof of accreditation you can verify
  • Whether the figure could change on the day
  • Exactly which parts of the system are covered

Choosing a duct cleaning contractor

The process

We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. For a village or hamlet like Ash Green, tell us about narrow lanes, gates and parking when you book.

  1. After the clean, we arrange a time to check the system.
  2. The same access points are opened up.
  3. Grease readings are taken again at set points.
  4. Photos are taken to show the condition after the clean.
  5. The results are reported, with anything missed flagged.

Getting ready for the visit

  • Find the previous report, if there is one
  • Mention any sign-in, permit or induction we need
  • Let us know how we reach the system, including roofs, risers and plant rooms

Vertical risers

Risers can be hard to get into. We record what can and cannot be reached.

What affects the cost of TR19 inspection

Some jobs are bigger than they look, and some smaller. The main factors:

  • How many systems or sites are involved
  • Access, including roofs, risers and ceiling voids
  • The condition of the system
  • The size of the system

Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before we start.

Helping us quote

To speed up the quote, please include:

  • Your opening hours and when the area is out of use
  • Wide photos of the system and the area around it
  • Any symptoms, from odd noises to smells or leaks
  • Where the site is and what kind of site it is

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

In-house cleaning or a specialist?

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.

Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.

Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Food hygiene inspections in Ash Green are the job of Guildford council’s environmental health team.
