TR19 inspection across Littleton Common

Grease, kitchens and Littleton Common

Food Standards Agency data counts about 53 restaurants, cafés and works canteens and about 19 takeaways within about 1.5 miles of central Littleton Common. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Surrey Fire and Rescue Service covers Littleton Common. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. In Littleton Common, food businesses are inspected by environmental health officers from Spelthorne council. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

School kitchens, at schools like Ashford CofE Primary School for example, are normally cleaned in the holidays so no lunches are lost. Where a hall near Parish Church of St Matthew, or anywhere in Littleton Common, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

How we handle TR19 inspection in Littleton Common

Think of a TR19 inspection as the diagnosis before the treatment. Readings, pictures and notes on access are gathered from end to end, so the quote and the clean fit the real system. The work covers deposit thickness tests, access surveys and post-clean checks, and people most often call us about an insurer’s request for a TR19 audit and uncertainty over how often to clean.

Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.

The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What the work involves, part by part

Vertical risers

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

Canopy and plenum

Behind the filters, the plenum catches plenty of grease. Readings and photos are taken in the plenum as part of every survey.

What your team can do, and what needs us

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.

Aftercare tips

Once we’ve finished, these simple steps help:

  • Keep to the recommended interval
  • Report grease dripping from the canopy
  • Share inspection reports with your insurer or broker when asked
  • Wipe the canopy surfaces regularly

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

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

Signs you need TR19 inspection in Littleton Common

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.

These are the problems we see most often:

  • An insurer’s request for a TR19 audit
  • Cleaning intervals that may not suit the kitchen
  • Extracts that may be over the 200 micron mean
  • Surveys needed before quoting a full clean

A hospital like Ashford Hospital, about 1.8 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Comparing quotes

  • Whether the quote shows VAT
  • How they set the interval to the next visit
  • What’s included in the scope, part by part
  • When they can work, and whether that is outside your opening hours

Littleton Common: your questions answered

Do you work at weekends in Littleton Common?

Yes, we can come after you close and finish before you open. Your customers, staff or residents in Littleton Common needn’t be disturbed. Tell us your opening hours when you ask for a quote.

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

Yes. Half-terms and the summer break are the natural time for school work. Around Littleton Common, the Food Standards Agency lists about 16 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.

What is a WFTT or DTT grease test?

The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. Readings are taken at set points through the system.

What do you do with what you remove?

We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.

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. We show your readings against those figures.

How far ahead should we book?

The more notice, the better, especially for out-of-hours work. We usually quote within one working day, and there’s a 24/7 line for emergencies.

What should I send you?

Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.

Is TR19 a legal requirement?

No. It’s the benchmark rather than the law. Without TR19 records, an insurance claim can be reduced or refused, so it matters in practice.

What happens on the day

Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a morning or less for one kitchen, more where there are several systems, and the area is cleaned down before we leave. The timing of a visit to Littleton Common is set by you, and the travel is our side of the planning.

  1. The visit is arranged for when the kitchen is not busy.
  2. The system is checked from canopy to discharge.
  3. Grease thickness is measured at set points by WFTT or DTT.
  4. Each test point and any access problems are photographed.
  5. We send a report setting out the readings, photos and next steps.

Getting ready for the visit

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Dig out any earlier paperwork for the system
  • Tell us the best time to work, such as after service or at a weekend
