TR19 inspection across Petersham

TR19 inspection for kitchens and businesses in Petersham

A grease test measures how thick the grease is inside a kitchen extract system. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). The results show whether the system needs cleaning and how soon. The work covers pre-clean surveys, post-clean checks and wet film thickness tests, and common reasons people get in touch are surveys needed before quoting a full clean and missing access panels found on survey.

Kitchens in Petersham, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.

A written report with photos follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Common problems we fix in Petersham

Some parts of a system are hard to reach, and grease can be missed there clean after clean. A survey finds the sections that cannot be reached, so panels can be fitted.

Most sites get in touch after spotting something like this:

  • Confirming a clean reached the whole system
  • Sites with gaps in their extract records
  • Parts of the system left out of past cleans
  • Extracts that may be over the 200 micron mean

If you run a café or takeaway near St Margarets (London) station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

How to choose an extract cleaning contractor

Why it’s worth doing now in Petersham

We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

Petersham: your questions answered

Which council inspects kitchens in Petersham?

Food hygiene inspections in Petersham are carried out by Richmond-Upon-Thames council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.

Do you work at weekends in Petersham?

Yes, we can come after you close and finish before you open. It means the site in Petersham keeps running as normal. Your opening times are the first thing we ask for.

What grease levels does TR19 allow?

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

What is TR19?

A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.

Do you offer maintenance contracts?

Yes, of course. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.

What does TR19 inspection cost?

Size, condition, access and working hours all affect the cost. Call for a fixed quote and we will normally reply within one working day.

Do you work with multi-site operators?

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

How long does a TR19 inspection take?

It takes a morning or less for one kitchen, more where there are several systems. We fit it around when the kitchen is closed or quiet.

How the visit works

We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes a couple of hours for a typical kitchen extract system. Security desks and permits-to-work are routine in London, so let us know what your building in Petersham needs from us.

  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. Photos are taken to show the condition after the clean.
  5. The results are reported, with anything missed flagged.

How to prepare

  • Arrange a key holder or contact on site
  • Mention any sign-in, permit or induction we need
  • Move anything stored near the system

Different parts, different methods

Vertical risers

In buildings with several floors, the riser may pass through other tenants’ space, so access is planned in advance.

Schools, hospitals and care homes

Inspections are planned around mealtimes and holidays so meals are not affected.

Multi-site and managed buildings

Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

Staff cleaning versus specialist work

A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.

Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

Between visits

Looking after the system between visits is straightforward, and it helps at the next visit:

  • Clean grease off the canopy between professional cleans
  • Diary the next grease test and clean
  • Clean or swap grease filters as often as the kitchen needs
  • Send TR19 audit reports to your insurer on request

Each report suggests the next clean and the next test, based on the readings and how the kitchen is used.

When cooking hours or the menu change, check the interval still fits. A quick grease test answers the question.

TR19 inspection around Petersham

The FSA’s food hygiene register shows about 224 cafés, restaurants and staff canteens and about 21 takeaways within roughly a mile and a half of the centre of Petersham. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. In London, kitchens are usually cleaned overnight, when the kitchen is closed and loading is easier. It’s Richmond-Upon-Thames council that sends environmental health officers to food businesses in Petersham. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready.

If you run catering at a healthcare site, such as a hospital like South Middlesex Hospital about 1.7 miles north-west, the extract may need cleaning more often than a part-time kitchen. If you look after a school kitchen, at a school such as The Russell Primary School or anywhere near Petersham, the holidays are the usual time for a TR19® clean.
