TR19 inspection for sites in Blendon

Kitchen extracts in Blendon

There are about 189 restaurants, cafés and canteens and about 85 takeaways and sandwich shops across Blendon and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Fire safety in Blendon falls to London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Kitchens in Blendon get their food hygiene inspections from Bexley council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

If you run a church or community hall kitchen, near St James the Great or elsewhere in Blendon, its extract still collects grease from every lunch and event. Commuter trade near Albany Park station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Healthcare kitchens, like those at hospitals such as Bexley Hospital (about 0.8 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

About our TR19 inspection in Blendon

After a clean, post-clean verification checks the result, with fresh grease readings, pictures and a look at the areas that were cleaned. It shows whether the system was left in the condition the paperwork describes. The work covers pre-clean surveys, post-clean checks and access surveys, and people most often call us about insurers asking for TR19 evidence and post-clean verification after another contractor’s clean.

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

The paperwork matters as much as the work. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

How we price TR19 inspection

A fixed price needs a few facts first. We check:

  • Any permits to work or inductions
  • Parking and loading at the site
  • Access, including roofs, risers and ceiling voids
  • The number of sites or systems

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

Helping us quote

A few details help us quote accurately. With your enquiry, please include:

  • The roof, plant room or outside wall the system runs to
  • When the site is open and when it’s quiet
  • Problems your staff have spotted
  • Detail shots of panels, filters and grilles

For TR19 inspection in Blendon, call 0345 646 2711, or send details by email. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. We usually send a fixed quote within one working day.

When something else is needed

TR19 inspection can’t fix everything, and we’d rather say so up front. It does not solve:

  • Ductwork that was designed or installed badly
  • Hidden runs that need access panels first
  • The responsible person’s own fire risk assessment

If in doubt, call 0345 646 2711 or send us an email and we will say what we think.

Where we work

  • Deposit thickness tests
  • Insurer audits
  • Post-clean checks
  • Pre-clean surveys
  • Wet film thickness tests
  • Access surveys

Blendon questions

Can a school canteen extract in Blendon be done out of term time?

Yes, holiday work suits schools best. Around Blendon, the Food Standards Agency lists about 33 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Do you work overnight in Blendon?

Yes, nights and weekends are routine for us. The site is handed back ready to open. When you call 0345 646 2711, or email photos, mention when the site is quiet.

Do you carry out TR19 audits for insurers?

Yes, for kitchens across the South East and London. Share the insurer’s request so the report addresses it.

How do you protect the area?

Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.

How much notice do you need?

For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.

What about areas you can’t get to?

They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.

How do you measure grease in a kitchen extract?

Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. Each reading is recorded in microns.

What grease levels does TR19 allow?

TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, with 500 microns or more anywhere needing immediate spot cleaning.

For landlords and multi-site operators

Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.

From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

What the work involves, part by part

Schools, hospitals and care homes

We fit testing around service times and school holidays so meals aren’t affected.

Extract fan and discharge

Grease on the fan adds to wear. The inspection shows whether it needs cleaning now.

What staff can safely do

If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.

Aftercare tips

How long the results last depends on use and care. Here’s what we suggest:

  • Diary the next grease test and clean
  • Clean or swap grease filters as often as the kitchen needs
  • Wipe the canopy surfaces regularly
  • File every inspection report with your certificates

For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.

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

How the visit works

We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes an hour or two for a single kitchen, longer for a large or complex system. We fit London jobs around the building rather than the other way round, so a visit in Blendon is typically out of hours.

  1. Post-clean verification is booked once the clean is done.
  2. The same access points are opened up.
  3. Grease readings are taken again at set points.
  4. Photos are taken to show the condition after the clean.
  5. We report the findings and flag any areas that need more work.

Getting ready for the visit

  • Tell us where we can park and unload
  • Arrange a key holder or contact on site
  • Let us know when the site is closed or quiet

How to get a quote

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
