TR19 inspection near Bull's Green

What staff can safely do

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.

How we handle TR19 inspection in Bull's Green

Post-clean verification is a check carried out once the cleaning is done, with fresh grease readings, pictures and a look at the areas that were cleaned. It gives you evidence of how the system was actually left. If you’re dealing with systems that need surveying before cleaning and checking the result of a recent clean, we can help.

Work in a small place like Bull's Green starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.

Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Different parts, different methods

Extract fan and discharge

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

Restaurants, pubs and hotels

We test between services, early in the morning or after close so the kitchen keeps cooking.

Questions from Bull's Green

Will you come out to Bull's Green?

Yes, Bull's Green is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.

Who would carry out a food hygiene inspection at a kitchen in Bull's Green?

The local authority for Bull's Green is East Hertfordshire council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Can you set up regular visits?

Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.

What if parts of the system can’t be reached?

The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.

Which sectors do you work in?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.

How do you measure grease in a kitchen extract?

We measure the grease at set points with a WFTT or DTT test, then compare them with the TR19® Grease figures.

Do you survey before quoting?

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

What do you do to protect the area?

Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.

What we’re called out for in Bull's Green

When a site in Bull's Green changes owner or cleaning contractor, the records don’t always follow. Without them, nobody knows how much grease is in the system or when it was last cleaned.

It’s time to book a visit if you see:

  • Ductwork where grease may be over the TR19 limits
  • Checking the result of a recent clean
  • Systems cleaned on a calendar with no measurements
  • Missing access panels found on survey

If your kitchen is in a listed or historic building, like the houses around Bull's Green (Digswell House is about 2.6 miles south-west), fitting access panels needs care.

Before booking anyone

  • Whether they recommend a next date
  • Whether a survey comes first
  • Whether the whole system is included, or only the parts that are easy to reach
  • What insurance they carry

How to choose an extract cleaning contractor

Keeping the system healthy

After the visit, a few habits help the work last:

  • Don’t box in or cover duct access panels
  • Mention new equipment or longer hours at the next test
  • Wipe the canopy surfaces regularly
  • File every inspection report with your certificates

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

Fit access panels where the survey finds sections cannot be reached, so grease isn’t left building in hidden parts.

How it works

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. On site, the work takes a morning or less for one kitchen, more where there are several systems. Seeing the system in pictures first means the trip to Bull's Green can be planned properly.

  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. Each test point and any access problems are photographed.
  5. The findings go into a report with readings, pictures and a recommended next clean.

Getting ready for the visit

Landlords, agents and facilities managers

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.

We also work for facilities teams across offices, schools and healthcare in Bull's Green and across Hertfordshire. Work can be phased by floor, building or site around the people who use them.
