TR19 inspection for sites in Coldharbour

What happens on the day

Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes a couple of hours for a typical kitchen extract system. For a job in Coldharbour, tell us about loading bays, permits, lifts and roof access when you book.

  1. The visit is arranged for when the kitchen isn’t busy.
  2. The system is checked from canopy to discharge.
  3. Grease readings are taken at set points using WFTT or DTT.
  4. We photograph the test points and record any sections we cannot reach.
  5. The findings go into a report with readings, pictures and a recommended next clean.

Getting ready for the visit

  • Clear the space around the work
  • Allow time for equipment near the work to be turned off and cool down
  • Let us know about permits to work or site inductions

About our TR19 inspection in Coldharbour

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). From the numbers, you can see whether cleaning is due. If you have parts of the system left out of past cleans and cleaning intervals that may not suit the kitchen, we can help, from insurer audits, deposit thickness tests and access surveys onwards.

London kitchens tend to trade late and open early, so extract cleaning in Coldharbour is normally done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.

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

Kitchen extracts in Coldharbour

Food Standards Agency records include about 40 pubs, bars and clubs and about 14 hotels and guest houses in and around Coldharbour, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Environmental health officers from Tower Hamlets council inspect food businesses in Coldharbour. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Coldharbour falls to London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

For schools such as Woolmore Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. If you cook for passing trade around Canary Wharf station, the extract can be cleaned between your last and first customer.

What happens if it’s left?

Without readings, you are guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. Leaving it on a busy London site only adds to the work.

When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.

Part by part

Canopy and plenum

Clean-looking filters don’t mean a clean plenum. That’s why we test behind them.

Schools, hospitals and care homes

Inspections are planned around mealtimes and holidays to avoid disruption.

Common questions in Coldharbour

Can you clean school kitchen extracts in Coldharbour during the holidays?

Yes, and it’s the easiest time to do it. With about 46 schools and colleges on the FSA’s register within roughly a mile and a half of Coldharbour, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.

Can you work in Coldharbour outside opening hours?

Yes, we can come after you close and finish before you open. It means the site in Coldharbour keeps running as normal. Just call 0345 646 2711, or email photos with your opening times and we’ll plan around them.

Can one contract cover all our sites?

Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.

Is there a survey before the work?

Yes. We always survey first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.

What does a pre-clean survey involve?

A survey finds out how the system is laid out, how dirty it is and what can be reached, before anyone starts cleaning. Any access problems are flagged so they can be sorted first.

Do you check other contractors’ cleans?

Verification means repeat readings and pictures once the clean is done. Any areas that weren’t cleaned properly are flagged.

Can you set up regular visits?

Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.

What happens to the waste?

Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.

Multi-site and managed buildings

When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.

Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.

Keeping the system healthy

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

  • Clean grease off the canopy between professional cleans
  • File every inspection report with your certificates
  • Have the latest report ready for insurance renewals
  • Don’t box in or cover duct access panels

Keep the verification report next to the certificate it relates to. The pair gives a clear record of the clean and the check.

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

What affects the quote in Coldharbour

The diagnosis comes before the price. The main factors are:

  • One-off work versus a regular cycle
  • Working hours and out-of-hours timing
  • Where the site is and how we reach it
  • Any permits to work or inductions

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 us an email for straight advice and a fixed quote.

What we need to know

The more you tell us, the more accurate the quote. When you get in touch, it helps to send:

  • When the site is open and when it’s quiet
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Your last certificate, test record or report
  • Detail shots of panels, filters and grilles

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. Add the site type and your opening hours, and many jobs can be priced from that alone.

Signs you need TR19 inspection in Coldharbour

When a site in Coldharbour changes owner or cleaning contractor, the records don’t always follow. With no history, the current state of the extract is a guess.

Common reasons sites call us are:

  • Systems that need surveying before cleaning
  • Cleaning intervals that may not suit the kitchen
  • Sites with gaps in their extract records
  • Post-clean verification after another contractor’s clean

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Poplar Hospital is the nearest hospital to Coldharbour, about 0.6 miles north.

What your quote should include

  • What happens if part of the system can’t be accessed
  • Proof of accreditation you can verify
  • Whether they’re fully insured
  • Whether they recommend a next date
