About our TR19 inspection in Chorleywood West

Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. A TR19 audit sets out the system’s condition, with readings and photos, for sites in Chorleywood West and the rest of Hertfordshire. If you have missing access panels found on survey and ductwork where grease may be over the TR19 limits, we can help, from insurer audits, pre-clean surveys and wet film thickness tests onwards.

In a small place like Chorleywood West, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.

It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Keeping the system healthy

Think of this as the after-treatment advice, in brief:

  • Report grease dripping from the canopy
  • Flag changes in how much frying the kitchen does
  • Keep TR19 certificates, readings and reports together
  • Keep access panels clear and unpainted

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.

What happens on the day

When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes an hour or two for a single kitchen, longer for a large or complex system. Rural roads and tight entrances are worth telling us about before a visit to Chorleywood West.

  1. First we look at the system’s cleaning history, if there is one.
  2. The layout is traced from the canopy to the discharge.
  3. We note where access panels are and where more are needed.
  4. Grease readings are taken and pictures recorded.
  5. You get a report and a fixed quote for the clean.

How to prepare

  • Dig out any earlier paperwork for the system
  • Clear loose items from the work area
  • Agree a time when the area can be out of use

How to get a quote

Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Advice

Your questions about TR19 inspection in Chorleywood West

Who carries out food hygiene inspections in Chorleywood West?

In Chorleywood West, it’s Three Rivers council that carries out food hygiene inspections. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

Do you clean school canteen extracts around Chorleywood West out of term?

Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 21 schools, colleges and universities with registered kitchens within about a mile and a half of Chorleywood West. Booking early in the term gives the best choice of holiday dates.

Is TR19 cleaning the law?

No. TR19® is a specification, not a statute. Without TR19 records, an insurance claim can be reduced or refused, so following it is the sensible course.

Do you carry out TR19 audits for insurers?

Yes. We inspect the system and produce a report with grease readings, photos and any inaccessible areas. You can pass it straight to your insurer or broker.

How often should a kitchen extract be inspected?

That varies with the kitchen’s daily use. BESA sets minimum cleaning intervals of 3, 6 or 12 months by daily use, and testing shows if your kitchen needs more.

Is there a survey before the work?

Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.

Can you look after several sites?

Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.

Which sectors do you work in?

Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.

Leave it or put it right?

Skipping grease testing leaves the cleaning interval to guesswork. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, and you can only act on that if you’ve measured it. Equipment tucked in a roof space or outbuilding near Chorleywood West rarely gets looked at unless someone books it.

Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

For landlords and multi-site operators

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.

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.

Grease, kitchens and Chorleywood West

Food Standards Agency records list about 38 restaurants, cafés and canteens and about 20 takeaways and sandwich shops within about 1.5 miles of central Chorleywood West. For any of them with a canopy, measuring grease is better than guessing when to clean. Food hygiene inspections in Chorleywood West are the job of Three Rivers council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Hertfordshire Fire and Rescue Service covers Chorleywood West. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

Healthcare kitchens, like those at hospitals such as Bishops Wood Hospital (about 2.8 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands. For kitchens close to Rickmansworth station, where the day often starts early and ends late, the extract can be cleaned overnight. If you look after a school kitchen, at a school such as Arnett Hills Junior Mixed and Infant School or anywhere near Chorleywood West, the holidays are the usual time for a TR19® clean.

What your team can do, and what needs us

Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Part by part

Horizontal duct runs

Sections without access are recorded so it can be fixed before the clean.

Canopy and plenum

Filters can look fine while the plenum behind them is heavily coated. So we measure behind the filters, not just in front.

How we price TR19 inspection

The survey tells us what the work involves. The main factors are:

  • One-off work versus a regular cycle
  • The condition we find in the survey
  • The size of the system
  • Where the site is and how we reach it

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.

Helping us quote

We can often survey from pictures. Try to include:

  • Any previous report or certificate
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • The site address and the type of premises
  • The times we could work without disrupting the site

For TR19 inspection in Chorleywood West, call us on 0345 646 2711, or email photos. Let us know the site type and the opening hours, and send photos or your last report if you can. We typically send a fixed quote within one working day.
