TR19 inspection for sites in Thames Ditton

What your team can do, and what needs us

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.

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, alongside our reports.

How we handle TR19 inspection in Thames Ditton

A pre-clean survey looks at the whole system, from canopy to discharge. Access is checked along the full length, and record grease readings at set points. The work covers deposit thickness tests, pre-clean surveys and insurer audits, and common reasons people get in touch are systems that need surveying before cleaning and cleaning intervals that may not suit the kitchen.

For a smaller kitchen near Thames Ditton, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.

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

Restaurants, pubs and hotels

Inspections are done when the kitchen is closed or quiet so trading isn’t affected.

Canopy and plenum

The plenum behind the filters can carry a lot of grease. We take readings there and photograph it on every inspection.

Questions from Thames Ditton

Who inspects food businesses in Thames Ditton?

The local authority for Thames Ditton is Elmbridge council, and its environmental health team does the inspecting. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

Do you work at weekends in Thames Ditton?

Yes, we can come after you close and finish before you open. Your customers, staff or residents in Thames Ditton needn’t be disturbed. Let us know the hours you’re closed and we will book within them.

Do you offer emergency callouts?

Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.

Can you look after several sites?

Yes. Tell us the addresses and what each needs and you will get one fixed quote.

Which accreditations do you hold?

Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Why survey before a clean?

We look at the system from canopy to discharge, take grease readings and check access. From it, we plan the clean and quote a fixed price.

Can you quote from photos?

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

What do you need from me for a quote?

Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply ring 0345 646 2711 or use the quote form.

Keeping the system healthy

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

  • Send TR19 audit reports to your insurer on request
  • Flag oily drips near the extract
  • Keep canopy edges and gutters wiped down
  • Keep to the recommended interval

After the inspection, we send a report showing each reading, its location and photos. Keep it with your fire safety and TR19 records.

Test grease regularly instead of relying on the calendar. It shows if build-up is speeding up.

When to call us in Thames Ditton

Looking at a canopy tells you little about what’s in the duct. Clean filters can hide a heavy layer behind them, which is why readings matter.

The symptoms we are asked about most are:

  • Extracts that may be over the 200 micron mean
  • Extracts that have never been grease tested
  • Uncertainty over how often to clean
  • Systems that need surveying before cleaning

Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Thames Ditton is Tolworth Hospital, about 2 miles east.

Thames Ditton kitchens: local notes

The Food Standards Agency lists about 36 pubs and bars as registered food businesses in and around Thames Ditton, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Environmental health officers from Elmbridge council inspect food businesses in Thames Ditton. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand. Thames Ditton sits within the area of Surrey Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

If you run a café or takeaway near Thames Ditton station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Where a hall near Church of St. Nicholas, or anywhere in Thames Ditton, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

The process

Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes a couple of hours for a typical kitchen extract system. In a place like Thames Ditton, we fit the visit around your hours.

  1. First we book a time that will not disrupt cooking.
  2. Every part of the system is examined, end to end.
  3. We take WFTT or DTT readings at set points along the system.
  4. Photos are taken at each point, and access gaps noted.
  5. You get a report with readings, photos and recommendations.

Getting ready for the visit

  • Clear loose items from the work area
  • Make sure equipment near the work can be switched off and left to cool
  • Agree a time when the area can be out of use

Getting 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 we can price many jobs without a visit.

Advice

What happens if it’s left?

Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Left alone, grease keeps building between cleans. It’s better to plan the work at a site near Thames Ditton than wait for a failure.

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 not sure what’s needed, call 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.

Why us?

  • CHAS, SafeContractor and ISO 9001
  • A fixed price before any work starts
  • Work around your opening hours, with 24/7 emergency cover
  • A written report with photos after every visit

When it’s something else

An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:

  • The legal duty, which stays with the responsible person
  • Heavy deposits found on test, which still need cleaning
  • Mechanical faults in the extract

If in doubt, ring 0345 646 2711, or email photos and we will say what we think.
