TR19 inspection for sites in Bernards Heath

TR19 inspection for kitchens and businesses in Bernards Heath

Before any clean in Bernards Heath, we survey the canopy, plenum, filters, ducts, fan and discharge. Access is checked along the full length, and record grease readings at set points. If you are dealing with ductwork where grease may be over the TR19 limits and insurance renewals needing proof of TR19 cleaning, we can put it right, from deposit thickness tests, wet film thickness tests and access surveys onwards.

Size does not change the work: a kitchen in a place like Bernards Heath gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.

Insurers, fire officers and environmental health officers all look at records. 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.

What we do, step by step

We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a morning or less for one kitchen, more where there are several systems. Your opening hours decide when we come to Bernards Heath, not ours.

  1. First we book a time that will not disrupt cooking.
  2. The system is checked from canopy to discharge.
  3. We take WFTT or DTT readings at set points along the system.
  4. We photograph the test points and record any sections we can’t reach.
  5. You get a report with readings, pictures and recommendations.

Preparing for the visit

  • Let us know about permits to work or site inductions
  • 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

What your team can do, and what needs us

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

Common problems we fix in Bernards Heath

You can’t judge grease thickness by eye. Clean filters can hide a heavy layer behind them, so readings are the reliable guide.

Any of these means the system needs a check-up:

  • Sections of duct that can’t be reached
  • Systems that need surveying before cleaning
  • An insurer’s request for a TR19 audit
  • Cleaning intervals that may not suit the kitchen

Bursars and site managers at schools such as Garden Fields Junior Mixed and Infant School tend to book extract cleaning for when the kitchen is empty.

Questions to ask before booking

  • What insurance they carry
  • Proof of accreditation you can verify
  • Whether the quote is based on a survey or photos
  • When the next visit should be, and why

How the job changes from site to site

Schools, hospitals and care homes

We fit testing around service times and school holidays to avoid disruption.

Horizontal duct runs

Grease settles on the floor of horizontal ducts as the air cools. We test at points along the run through access panels.

What TR19 inspection cannot fix

Some problems need a different service or another trade:

  • Installation problems, which fall under design guidance such as DW172
  • Heavy deposits found on test, which still need cleaning
  • Sections with no access, until panels are fitted

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

TR19 inspection in Bernards Heath: the local picture

Look up Bernards Heath on the FSA’s food hygiene register and you’ll find about 159 restaurants, cafés and canteens and about 34 takeaways within 1.5 miles or so of the middle of Bernards Heath. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Bernards Heath sits within the area of 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. It’s St Albans City council that sends environmental health officers to food businesses in Bernards Heath. 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.

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St Albans City Hospital is the nearest hospital to Bernards Heath, about less than half a mile west. A hall kitchen that only cooks for events, whether near Church of St Saviour or elsewhere in Bernards Heath, still needs its extract cleaned, just less often.

  • How big the system is
  • What state the system is in
  • How many systems or sites are involved

What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.

Questions from Bernards Heath

Who inspects food businesses in Bernards Heath?

That’s St Albans City council, whose environmental health officers carry out food hygiene inspections in Bernards Heath. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Who is the fire and rescue service for Bernards Heath?

Hertfordshire Fire and Rescue Service is the fire and rescue service for Bernards Heath. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Do you work with multi-site operators?

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

Can we book visits on a schedule?

Yes. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.

Are you accredited?

We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What’s TR19?

A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.

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, before anyone starts cleaning. Missing access panels are noted ahead of the clean.

What happens to the waste?

Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.

Why act early in Bernards Heath

Surveying first means the clean goes to plan. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, so the clean covers the whole system. Booking ahead lets us plan the trip to Bernards Heath at a time that suits you.

The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.
