What your team can do, and what needs us

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.

TR19 inspection for kitchens and businesses in Hunsdonbury

Not every kitchen fits neatly into a calendar. Some kitchens build up grease faster than the minimum intervals assume, and only measurement shows it. Our readings give your risk assessment real numbers to work from. The work covers pre-clean surveys, insurer audits and wet film thickness tests, and common reasons people get in touch are confirming a clean reached the whole system and missing access panels found on survey.

Work in a small place like Hunsdonbury starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

When it’s something else

TR19 inspection cannot fix everything, and we’ll tell you before work begins. It does not solve:

  • Design faults in the extract system
  • A faulty or failing extract fan

If you’re not sure, just give us a ring on 0345 646 2711 or use the quote form and we’ll give you a straight answer before booking.

Parts of the system we cover

Kitchen extracts in Hunsdonbury

According to Food Standards Agency records, there are about 4 pubs, bars and clubs within roughly a mile and a half of the centre of Hunsdonbury. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Hunsdonbury sits within the area of Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Environmental health officers from East Hertfordshire council inspect food businesses in Hunsdonbury. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.

A hall kitchen that only cooks for events, whether near St Francis Chapel or elsewhere in Hunsdonbury, still needs its extract cleaned, just less often. For schools such as Hunsdon Junior Mixed and Infant School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

Hunsdonbury questions

Which fire authority looks after Hunsdonbury?

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

Is Hunsdonbury within the area you cover?

Yes. Hunsdonbury is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you work with multi-site operators?

Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.

When should we have our next grease test?

Each report recommends when to test and clean next, based on the readings and how the kitchen is used. A risk assessment based on measured grease should set the interval.

What is TR19?

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.

How do you measure grease in a kitchen extract?

It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. Each reading is recorded in microns.

Do you have a 24/7 line?

Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.

How long does grease testing take?

An inspection takes an hour or two for a single kitchen, longer for a large or complex system. Large or multiple systems take longer, so give us a ring on 0345 646 2711 or email us and we will plan it.

How it works

Your trading hours come first. 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 an hour or two for a single kitchen, longer for a large or complex system. In a small place like Hunsdonbury, the journey is planned ahead and the visit arranged around the site’s hours.

  1. First we book a time that will not disrupt cooking.
  2. We look over the canopy, plenum, ducts, fan and discharge.
  3. Grease thickness is measured at set points by WFTT or DTT.
  4. We photograph the test points and record any sections we cannot reach.
  5. The findings go into a report with readings, pictures and a recommended next clean.

How to prepare

  • Tell us where we can park and unload
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Clear the space around the work

Aftercare tips

No system stays clean for ever, but care slows the build-up. Our tips:

  • Book the next test on the date in the report
  • Keep TR19 certificates, readings and reports together
  • Wipe the canopy surfaces regularly
  • Never cook with filters missing

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

Keep all TR19 records together so the history is easy to show.

Do you need TR19 inspection in Hunsdonbury?

When a site in Hunsdonbury changes owner or cleaning contractor, the records do not always follow. Without them, nobody knows how much grease is in the system or when it was last cleaned.

Keep an eye out for these warning signs:

  • Sites with gaps in their extract records
  • An insurer’s request for a TR19 audit
  • Surveys needed before quoting a full clean
  • Uncertainty over how often to clean

Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Hunsdonbury is Princess Alexandra Hospital, about 2.5 miles south-east.

What your quote should include

  • Whether the work can be done while the site is closed
  • What insurance they carry
  • If they look at the system before pricing
  • Whether VAT is included

Choosing a duct cleaning contractor

How the job changes from site to site

Canopy and plenum

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

Horizontal duct runs

If a run has no access panel, we note it so it can be fixed before the clean.

For landlords and multi-site operators

When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.

Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
