How we handle TR19 inspection in Headstone

A pre-clean survey is the diagnosis, and the clean is the treatment. We look at the system, take grease readings and photograph what we find, so the quote and the clean fit the real system. If you’re dealing with uncertainty over how often to clean and post-clean verification after another contractor’s clean, we can help.

Kitchens in Headstone, 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.

Good records are part of the job. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What a clean won’t put right

Not every problem is solved by TR19 inspection, and we’d rather say so up front. It will not put right:

  • Installation problems, which fall under design guidance such as DW172
  • Fan breakdowns, which need a repair visit
  • The responsible person’s own fire risk assessment

If in doubt, give us a ring on 0345 646 2711 or send us an email and we’ll say what we think before you book.

Managing agents and facilities teams in Headstone

Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.

If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.

TR19 inspection in Headstone: the local picture

Look up Headstone on the FSA’s food hygiene register and you’ll find about 114 cafés, restaurants and staff canteens and about 38 sandwich bars and takeaways across Headstone and its immediate surroundings (about a mile and a half). Each kitchen extract among them can be measured for grease to set the right cleaning interval. Headstone sits within the area of London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Overnight is the normal time to clean a London kitchen extract, so trading is not affected.

Commuter trade near Headstone Lane station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. If you run catering at a healthcare site, such as a hospital like Northwood and Pinner Cottage Hospital about 2.2 miles west, the extract may need cleaning more often than a part-time kitchen. Term dates shape school work: for a school like Pinner Park Primary School, an extract clean fits neatly into a half-term or summer break.

What your team can do, and what needs us

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

What affects the quote in Headstone

The survey tells us what the work involves. We look at:

  • The times the site is available
  • Parking and loading at the site
  • One-off work versus a regular cycle
  • The number of sites or systems

Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.

What we need to know

When you call or email, these details help:

  • Any previous report or certificate
  • Detail shots of panels, filters and grilles
  • The roof, plant room or outside wall the system runs to
  • Photos showing the whole system and its surroundings

We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711 or email us.

FAQs for Headstone

Who inspects food businesses in Headstone?

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

Does London parking affect a job in Headstone?

A loading bay, a visitor permit or off-street space near the site in Headstone makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit typically gets round them.

What is grease thickness testing?

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.

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 do you need from me for a quote?

Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply give us a ring on 0345 646 2711, or send details by email.

Do you look at the system first?

Yes. We always survey first, from your pictures and details, or with a visit where needed. A fixed quote follows.

Can you come out in an emergency?

Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.

Is a quote from pictures possible?

Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. Some sites still need a visit, and we’ll say so.

How it works

A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the TR19 inspection, tidy up and leave you the report. The visit itself takes a couple of hours for a typical kitchen extract system. In a London area like Headstone, parking, loading and building access are planned before the day of the work.

  1. Post-clean verification is booked once the clean is done.
  2. We open the access points used on the clean.
  3. Grease readings are taken again at set points.
  4. We photograph each area to record how it was left.
  5. We report the findings and flag any areas that need more work.

How to prepare

  • Mention any parking or loading restrictions
  • Allow time for equipment near the work to be turned off and cool down
  • Mention any locked doors, roof access or ceiling voids

How to get a quote

The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Keeping the system healthy

Aftercare is simple, and it helps at the next visit:

  • Send TR19 audit reports to your insurer on request
  • Don’t box in or cover duct access panels
  • Store grease readings where your insurer can see them
  • Clean grease off the canopy between professional cleans

After post-clean verification, file the results with the cleaning certificate. Together they show the system was cleaned and checked.

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

What happens if it’s left?

Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Ignored, the layer only gets thicker. Choosing the date yourself beats having a fault choose it for you.

The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.
