About our TR19 inspection in Allen's Green

Post-clean verification is a check carried out once the cleaning is done, with new readings and pictures of the cleaned areas. It gives you evidence of how the system was actually left. The work covers wet film thickness tests, insurer audits and deposit thickness tests, and people most often call us about confirming a clean reached the whole system and missing TR19 certificates or history.

Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.

The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Advice

TR19 inspection around Allen's Green

The FSA’s food hygiene register shows about 4 restaurants, cafés and works canteens within about 1.5 miles of central Allen's Green. Each kitchen extract among them can be measured for grease to set the right cleaning interval. The fire and rescue service for Allen's Green is 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. Kitchens in Allen's Green get their food hygiene inspections from East Hertfordshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.

If you run catering at a healthcare site, such as a hospital like Herts and Essex Hospital about 3.4 miles north-east, the extract may need cleaning more often than a part-time kitchen. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Much Hadham Palace is about 2.2 miles north-west), access may need planning.

Between visits

Looking after the system between visits is straightforward, and it makes the next visit easier:

  • Do not box in or cover duct access panels
  • Send TR19 audit reports to your insurer on request
  • Keep grease filters clean and fitted properly
  • File every inspection report with your certificates

You get a report with the grease readings, where they were taken and pictures of each point. Keep it with your fire safety and TR19 records.

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

What the work involves, part by part

Horizontal duct runs

If a run has no access panel, we note it so panels can be added.

Canopy and plenum

We look over the canopy, inside and out, and note where grease has gathered.

What your team can do, and what needs us

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.

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. The inside of ducts and units needs a specialist.

Questions from Allen's Green

Which environmental health team covers Allen's Green?

In Allen's Green, it’s East Hertfordshire council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Is Allen's Green within the area you cover?

Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.

Is TR19 cleaning the law?

No. TR19® is a specification, not a statute. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so following it is the sensible course.

What do you do with what you remove?

It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.

Do you check other contractors’ cleans?

A post-clean check records grease readings and pictures after the work, whoever did the clean.

Can you set up regular visits?

Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.

How often should grease be tested?

Often enough to know the mean stays under 200 microns between cleans. If readings rise, the interval should shorten.

What is grease thickness testing?

The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. Readings are taken at set points through the system.

Common problems we fix in Allen's Green

Insurers, fire officers and environmental health officers look to TR19® as the benchmark. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and grease in the extract is part of that risk.

It’s time to book a visit if you see:

  • Kitchens whose menu or hours have changed
  • Missing access panels found on survey
  • Missing TR19 certificates or history
  • Systems that need surveying before cleaning

A hall kitchen that only cooks for events, whether near Former Church of St Anne or elsewhere in Allen's Green, still needs its extract cleaned, just less often.

How to choose an extract cleaning contractor

What affects the cost of TR19 inspection

You will get a fixed price before work begins. It’s based on:

  • The times the site is available
  • Whether several sites go on one quote
  • Parking and loading at the site
  • Site requirements such as sign-in and permits

Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

What we need to know

Many jobs can be priced from photos and some basics. Send what you can of the following:

  • How we’d reach plant on a roof or in a plant room
  • Your last certificate, test record or report
  • Your opening hours and when the area is out of use
  • Photos showing the whole system and its surroundings

There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, ring 0345 646 2711 or send us an email.
