TR19 inspection in Little Berkhamsted

Part by part

Vertical risers

Vertical risers take the extract up through the floors. Grease can drain down and pool at the bottom, so we check there.

Canopy and plenum

We look over the canopy, inside and out, with readings where grease collects.

TR19 inspection in Little Berkhamsted

A fixed schedule doesn’t always match how a kitchen really cooks. Some kitchens build up grease faster than the minimum intervals assume, which is why measurement matters. Our readings give your risk assessment real numbers to work from. Common call-outs are for heavy grease suspected in the plenum or ducts and sites with gaps in their extract records, on pre-clean surveys, access surveys and wet film thickness tests.

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

For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Honest limits

An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection won’t do:

  • The legal duty, which stays with the responsible person
  • A faulty or failing extract fan
  • Heavy deposits found on test, which still need cleaning

If you are not sure, just call 0345 646 2711 or send us an email and we’ll give you a straight answer.

What we work on in Little Berkhamsted

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

How it works

Every visit runs to the same pattern: protect the area, make the system safe, do the work, clear away and hand over the paperwork. The visit itself takes around an hour or two per canopy and duct system. For a village or hamlet like Little Berkhamsted, tell us about narrow lanes, gates and parking when you book.

  1. The visit is arranged for when the kitchen is not busy.
  2. We look over the canopy, plenum, ducts, fan and discharge.
  3. Grease thickness is measured at set points by WFTT or DTT.
  4. Each test point and any access problems are photographed.
  5. The findings go into a report with readings, photos and a recommended next clean.

Before we arrive

  • Move anything stored near the system
  • Mention any parking or loading restrictions
  • Let us know how we reach the system, including roofs, risers and plant rooms

Advice

What staff can safely do

Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Little Berkhamsted kitchens: local notes

The FSA’s food hygiene register includes about 3 bars, pubs and nightclubs in Little Berkhamsted and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Fire safety in Little Berkhamsted falls to Hertfordshire 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. In Little Berkhamsted, food businesses are inspected by environmental health officers from East Hertfordshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand.

If you run catering at a historic house or estate in the area (Hatfield House is about 3.5 miles west), event kitchens in older buildings often have awkward duct runs that need planning. If you run catering at a healthcare site, such as a hospital like Queen Elizabeth II Hospital about 3.2 miles north-west, the extract may need cleaning more often than a part-time kitchen.

Signs you need TR19 inspection in Little Berkhamsted

As hot, greasy air travels up the duct, it cools and leaves a film behind. It often collects where nobody can see it: the plenum, bends and horizontal runs.

Keep an eye out for these warning signs:

  • Kitchens taken over with no cleaning records
  • Systems cleaned on a calendar with no measurements
  • An insurer’s request for a TR19 audit
  • Sections of duct that can’t be reached

If you run a church or community hall kitchen, near Church of St Andrew or elsewhere in Little Berkhamsted, its extract still collects grease from every lunch and event.

Our hiring checklist

Keeping the system healthy

Results last longer with the right care. We suggest:

  • Keep grease filters clean and fitted properly
  • Share inspection reports with your insurer or broker when asked
  • Wipe the canopy surfaces regularly
  • Keep to the recommended interval

The report recommends when the system should next be cleaned and tested, based on the readings and how the kitchen is used.

When cooking hours or the menu change, check the interval still fits. A quick grease test answers the question.

Little Berkhamsted questions

Can you clean school kitchen extracts in Little Berkhamsted during the holidays?

Yes, holiday work suits schools best. Around Little Berkhamsted, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.

Who enforces fire safety at workplaces in Little Berkhamsted?

It’s Hertfordshire Fire and Rescue Service, which covers Little Berkhamsted. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

What do you do with what you remove?

It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.

Can you inspect our extract for our insurance company?

Yes. Insurers often want evidence the extract is managed to TR19®, and our audit gives a clear record of the system’s condition, with recommendations where something needs doing.

How do you measure grease in a kitchen extract?

Grease thickness testing measures the layer of grease on the duct surfaces, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). The results are given in microns.
