How we handle TR19 inspection in St Ippolyts

Not every kitchen fits neatly into a calendar. In a busy kitchen, grease can build faster than the minimum intervals allow for, and only measurement shows it. Our readings give your risk assessment real numbers to work from. If you have extracts that may be over the 200 micron mean and insurers asking for TR19 evidence, we can put it right.

Somewhere as small as St Ippolyts, 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.

Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

For landlords and multi-site operators

Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.

Part by part

Extract fan and discharge

The discharge at the end of the system is checked as well, as grease can build up there too.

Horizontal duct runs

Flat duct runs collect grease along their base. Readings are taken along each run through its access panels.

How it works

Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes around an hour or two per canopy and duct system. Somewhere as small as St Ippolyts, the date and timings are agreed with you well before the day.

  1. First we look at the system’s cleaning history, if there is one.
  2. We follow the extract from canopy to discharge.
  3. Access panels are located and any missing ones noted.
  4. Grease readings are taken and photos recorded.
  5. You get a report and a fixed quote for the clean.

Getting ready for the visit

  • Make sure someone can let us in and lock up afterwards
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Mention any parking or loading restrictions

Questions from St Ippolyts

Is St Ippolyts within the area you cover?

Yes. Villages and rural sites across the South East are part of our work, St Ippolyts included. A survey first, from pictures or a visit, means we arrive with the right kit.

Who is the fire and rescue service for St Ippolyts?

It’s Hertfordshire Fire and Rescue Service, which covers St Ippolyts. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Can you quote from pictures?

Yes, for many jobs. 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 will say so.

What happens on a pre-clean survey?

A survey finds out how the system is laid out, how dirty it is and what can be reached, so the clean goes to plan. Missing access panels are noted ahead of the clean.

What do the grease readings need to be?

TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, and anywhere at 500 microns or more needs spot cleaning right away.

How do you keep the site clean during the work?

We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.

Which accreditations do you hold?

CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.

Can you work evenings and weekends?

Yes, and that’s how we prefer to work. The visit is timed for when the area isn’t in use, whether that’s late evening, overnight or a weekend.

Do you need TR19 inspection in St Ippolyts?

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 any of the following:

  • Confirming a clean reached the whole system
  • Surveys needed before quoting a full clean
  • Sites with gaps in their extract records
  • Extracts that may be over the 200 micron mean

If you look after a school kitchen, at a school such as St Ippolyts Church of England Aided Primary School or anywhere near St Ippolyts, the holidays are the usual time for a TR19® clean.

St Ippolyts kitchens: local notes

According to Food Standards Agency records, there are about 17 bars, pubs and nightclubs and about 3 hotels and B&Bs within roughly a mile and a half of the centre of St Ippolyts. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. In St Ippolyts, food businesses are inspected by environmental health officers from North Hertfordshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready. The fire and rescue service for St Ippolyts is Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

Historic houses near St Ippolyts, such as Knebworth House about 4.4 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes. If you run catering at a healthcare site, such as a hospital like Lister Hospital about 2 miles east, the extract may need cleaning more often than a part-time kitchen.

In-house cleaning or a specialist?

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

Keeping the system healthy

Think of this as the after-treatment advice, short and simple:

  • Never cook with filters missing
  • Keep TR19 certificates, readings and reports together
  • Keep access panels clear and unpainted
  • Clean grease off the canopy between professional cleans

Keep the verification report next to the certificate it relates to. Together they show the system was cleaned and checked.

Keep certificates, reports and readings in one place so you can produce them quickly.
