TR19 inspection in Childs Hill

TR19 inspection in Childs Hill

BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Those are minimums, and grease readings help set the real interval. If you have extracts that may be over the 200 micron mean and parts of the system left out of past cleans, we can put it right.

Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. In Childs Hill, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.

For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

For landlords and multi-site operators

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

When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.

Childs Hill questions

Which fire service covers Childs Hill?

It’s London Fire Brigade, which covers Childs Hill. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Can you work in Childs Hill outside opening hours?

Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Childs Hill needn’t be disturbed. Your opening times are the first thing we ask for.

How often should grease be tested?

Often enough to know the mean stays under 200 microns between cleans. The readings themselves tell you if the interval needs to change.

What happens on a pre-clean survey?

We survey, measure and photograph the system first. The survey can be done from photos and details or on site, whichever suits the system.

What does TR19 inspection cost?

The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, normally ready within one working day.

Which sectors do you work in?

All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.

What is grease thickness testing?

Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. The results are given in microns.

What happens if you can’t reach some of it?

Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.

What happens if it’s left?

Catching heavy deposits early keeps the fix small. Left alone, grease keeps building between cleans. A busy site in Childs Hill builds up dirt and wear quickly, so putting it off makes the eventual job larger.

You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711 or email us, and we will talk you through it.

Staff cleaning versus specialist work

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

How it works

The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes anything from an hour for a small canopy and short duct to a good part of a day for a large site, and the area is cleaned down before we leave. Loading bays, visitor permits and roof access are the first things we ask about for a site in Childs Hill.

  1. We go through any past certificates and reports.
  2. The layout is traced from the canopy to the discharge.
  3. We note where access panels are and where more are needed.
  4. We measure the grease and photograph each point.
  5. You get a report and a fixed quote for the clean.

Before we arrive

  • Tell us where we can park and unload
  • Mention any sign-in, permit or induction we need
  • Let us know when the site is closed or quiet

Ask for a quote

There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To start, give us a ring on 0345 646 2711 or email us.

Kitchen extracts in Childs Hill

The FSA’s food hygiene register shows about 303 cafés, restaurants and staff canteens and about 100 takeaways within about 1.5 miles of central Childs Hill. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Food hygiene inspections in Childs Hill are the job of Barnet council’s environmental health team. 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. In London, kitchens are usually cleaned overnight, when the kitchen is closed and loading is easier.

Church and community hall kitchens, near All Saints or anywhere around Childs Hill, are easy to forget, but their extracts collect grease like any other. A kitchen near Cricklewood station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; New End Hospital is the nearest hospital to Childs Hill, about 0.9 miles east.

What the work involves, part by part

Canopy and plenum

We look over the canopy, inside and out, and note where grease has gathered.

Vertical risers

Risers carry the extract up through the building. Grease can drain down and pool at the bottom, so we check there.

Between visits

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

  • Diary the next grease test and clean
  • Share inspection reports with your insurer or broker when asked
  • Wipe the canopy surfaces regularly
  • Flag oily drips near the extract

If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can quote to do it.

Keep filters clean and in place. Gaps around filters let grease get past them.
