TR19 inspection in Knave's Ash: the local picture

At about 3 miles from the coast, Knave's Ash is close enough for sea air to matter. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. Food Standards Agency data counts about 5 cafés, restaurants and staff canteens in Knave's Ash and the streets around it, up to about 1.5 miles out. Each kitchen extract among them can be measured for grease to set the right cleaning interval. Knave's Ash sits within the area of Kent Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.

Volunteers running a hall kitchen near Church of the Holy Cross, or anywhere in Knave's Ash, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Knave's Ash is St Martins Hospital, about 4.4 miles south-west.

Knave's Ash is about 2 miles south of Herne Bay, in Kent.

TR19 inspection in Knave's Ash

TR19® Grease says grease should not exceed a mean of 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Grease testing shows which side of those lines you are on. Common call-outs are for confirming a clean reached the whole system and extracts that may be over the 200 micron mean, on wet film thickness tests, pre-clean surveys and insurer audits.

Somewhere as small as Knave's Ash, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.

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.

When something else is needed

TR19 inspection cannot fix everything, and we’d rather say so up front. It won’t put right:

  • Fire safety duties beyond the extract system
  • Removing the grease, which is a separate clean
  • Installation problems, which fall under design guidance such as DW172

Not sure which it is? You can call us on 0345 646 2711, or send details by email and we’ll tell you honestly.

Parts of the system we cover

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

What we are called out for in Knave's Ash

Grease builds up as cooking vapour cools inside the extract. It often collects where nobody can see it: the plenum, bends and horizontal runs.

It’s time to book a visit if you see:

  • Post-clean verification after another contractor’s clean
  • Systems cleaned on a calendar with no measurements
  • Uncertainty over how often to clean
  • Insurers asking for TR19 evidence

For schools such as Hoath Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

Questions to ask before you book

  • Proof of accreditation you can verify
  • Whether they recommend a next date
  • Whether a survey comes first
  • How areas they can’t reach will be recorded

Choosing a duct cleaning contractor

The process

Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes an hour or two for a single kitchen, longer for a large or complex system. If the van will struggle with a lane or gateway near Knave's Ash, let us know and we’ll plan around it.

  1. First we look at the system’s cleaning history, if there is one.
  2. We follow the extract from canopy to discharge.
  3. We note where access panels are and where more are needed.
  4. Grease readings are taken and photos recorded.
  5. We report back with readings and a fixed quote.

Getting ready for the visit

  • Move anything stored near the system
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Dig out any earlier paperwork for the system

Advice

Fixed quotes for TR19 inspection in Knave's Ash

Your quote is based on your site. We consider:

  • Whether it’s a one-off visit or part of a schedule
  • Site rules, permits and inductions
  • The times the site is available
  • The size of the system

Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, call us on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

Helping us quote

To help us quote quickly, send us:

  • Any access panels or hatches you can see
  • A few general shots of the system
  • The site address and the type of premises
  • The roof, plant room or outside wall the system runs to

For a fixed quote, call 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll usually have a quote within one working day.

Your questions about TR19 inspection in Knave's Ash

Who would carry out a food hygiene inspection at a kitchen in Knave's Ash?

In Knave's Ash, it’s Canterbury City council that carries out food hygiene inspections. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.

Can you get to a site in Knave's Ash?

Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.

Is TR19 cleaning the law?

No, not in itself. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, and grease in the extract is part of that. Many insurance policies also require TR19 adherence.

How often should a kitchen extract be inspected?

We suggest a next test date in every report, taking the readings and the kitchen’s hours into account. The interval should come from a competent person’s risk assessment backed by grease measurement.

How much time does an inspection need?

As a guide, it takes around an hour or two per canopy and duct system. The size of the system and the access make the difference.

Can one contract cover all our sites?

Yes. Send the list of sites and the work at each and we’ll quote them together.

Do you survey before quoting?

Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.

Can you price the work without visiting?

Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.

Why deal with it now?

Catching heavy deposits early keeps the fix small. Ignored, the layer only gets thicker. Out of sight is the usual reason a rural system goes too long without attention.

The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

For landlords and multi-site operators

Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.

Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.

How the job changes from site to site

Extract fan and discharge

Grease builds up on the fan blades and inside the housing. They’re included in the readings and photos.

Schools, hospitals and care homes
