Aftercare tips

No system stays clean for ever, but care slows the build-up. A few tips:

  • Keep access panels clear and unpainted
  • Store grease readings where your insurer can see them
  • Diary the next grease test and clean
  • Send TR19 audit reports to your insurer on request

Any access problems we found are listed with a suggested fix. Fitting them before the next clean means the whole system gets done.

Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.

TR19 inspection for kitchens and businesses in Walliswood

TR19® Grease says grease should not exceed a mean of 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Testing is how you know where your system stands. If you have an insurer’s request for a TR19 audit and kitchen extract systems with no recent grease readings, we can put it right.

Somewhere as small as Walliswood, 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.

FAQs for Walliswood

Is Walliswood within the area you cover?

Yes, Walliswood is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.

Who carries out food hygiene inspections in Walliswood?

That is Mole Valley council, whose environmental health officers carry out food hygiene inspections in Walliswood. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Do you offer emergency callouts?

Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.

Can you work evenings and weekends?

Yes. Evenings, nights and weekends are normal working hours for us, so you do not have to close during trading.

What is grease thickness testing?

WFTT and DTT are the two methods for measuring grease thickness, in microns. Readings are taken at set points through the system.

How often should a kitchen extract be inspected?

That varies with the kitchen’s daily use. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and grease readings help set the real interval.

What do the grease readings need to be?

The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. Our report sets your readings against both.

Do you check other contractors’ cleans?

It’s an inspection after cleaning, to show what state the system was left in, for our cleans and other firms’ alike.

What happens on the day

We start by comparing what we find with the survey or your photos. 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. For a village or hamlet like Walliswood, tell us about narrow lanes, gates and parking when you book.

  1. After the clean, we arrange a time to check the system.
  2. We open the access points used on the clean.
  3. We repeat the WFTT or DTT readings.
  4. We photograph each area to record how it was left.
  5. The results are reported, with anything missed flagged.

How to prepare

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Name a contact who can let us in at the agreed time
  • Plan for cooking equipment or plant to be off before we arrive

What affects the cost of TR19 inspection

You will get a fixed price before any work starts. It’s based on:

  • Working hours and out-of-hours timing
  • How big the system is
  • Whether we need access equipment or extra panels
  • The condition of the system

Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, give us a ring on 0345 646 2711, or send details by email for straight advice and a fixed quote.

What we need to know

You do not need the technical terms. Just send:

  • Any access panels or hatches you can see
  • The paperwork from the last visit, if you have it
  • The times we could work without disrupting the site
  • The roof, plant room or outside wall the system runs to

The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

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. Send the address, what’s needed and how access works, and we’ll send a fixed quote.

Do you need TR19 inspection in Walliswood?

Insurers, fire officers and environmental health officers look to TR19® as the benchmark. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and in a kitchen that means keeping grease under control.

The symptoms we are asked about most include:

  • Post-clean verification after another contractor’s clean
  • Missing access panels found on survey
  • Surveys needed before quoting a full clean
  • Extracts that have never been grease tested

Healthcare kitchens, like those at hospitals such as Horsham Hospital (about 5.5 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Before you book anyone

  • Whether the figure could change on the day
  • How they set the interval to the next visit
  • What’s included in the scope, part by part
  • Whether VAT is included
