TR19 inspection across Westhumble

When it’s something else

In fairness, there are a few things this work will not fix:

  • The responsible person’s own fire risk assessment
  • Removing the grease, which is a separate clean
  • Installation problems, which fall under design guidance such as DW172

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

TR19 inspection in Westhumble

BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Grease testing shows whether your kitchen needs cleaning more often than that. If you have post-clean verification after another contractor’s clean and parts of the system left out of past cleans, we can help.

Work in a small place like Westhumble starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.

Each visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

How the visit works

Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. If the van will struggle with a lane or gateway near Westhumble, let us know and we’ll plan around it.

  1. After the clean, we arrange a time to check the system.
  2. The same access points are opened up.
  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.

Preparing for the visit

  • Have your last certificate or report to hand
  • Make sure equipment near the work can be switched off and left to cool
  • Arrange a key holder or contact on site

What affects the quote in Westhumble

We quote each job individually. This is what makes a difference:

  • A single visit or a regular plan
  • Any permits to work or inductions
  • How many systems or sites are involved
  • Parking and loading at the site

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.

What we need to know

When you call or email, it’s useful to have:

  • Wide photos of the system and the area around it
  • Any previous report or certificate
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Where the plant sits or the system leaves the building, such as a roof or outside wall

Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Multi-site and managed buildings

Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.

Looking after it afterwards

Good habits slow the build-up between visits. A few tips:

  • Mention new equipment or longer hours at the next test
  • Have the latest report ready for insurance renewals
  • Clean or swap grease filters as often as the kitchen needs
  • Do not box in or cover duct access panels

After post-clean verification, file the results with the cleaning certificate. The pair gives a clear record of the clean and the check.

Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.

Westhumble questions

Do you work overnight in Westhumble?

Yes, we can come after you close and finish before you open. That way a site in Westhumble doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.

Do you do school kitchen extract cleaning in Westhumble in the summer holidays?

Yes, and it’s the easiest time to do it. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Westhumble, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.

What is a WFTT or DTT grease test?

It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. The results are given in microns.

Can one contract cover all our sites?

Yes. Send the list of sites and the work at each and we will quote them together.

Can you quote from pictures?

In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.

Where does the waste go?

We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.

Can you come out in an emergency?

Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.

Do you offer maintenance contracts?

Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.

Kitchen extracts in Westhumble

According to Food Standards Agency records, there are about 3 bars, pubs and nightclubs and about 4 hotels and B&Bs within roughly a mile and a half of the centre of Westhumble. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Kitchens in Westhumble get their food hygiene inspections from Mole Valley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand. Fire safety in Westhumble falls to Surrey Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

A kitchen near Box Hill & Westhumble station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. Bursars and site managers at schools such as The Ashcombe School tend to book extract cleaning for when the kitchen is empty. Church and community hall kitchens, near Church of St Michael or anywhere around Westhumble, are easy to forget, but their extracts collect grease like any other.

Part by part

Canopy and plenum

The plenum behind the filters can carry a lot of grease. We take readings there and photograph it on every inspection.

Extract fan and discharge

We look at where the extract discharges outside, since grease reaches the very end of the system.
