Need TR19 inspection in Whempstead?

In-house cleaning or a specialist?

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.

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.

TR19 inspection in Whempstead

A grease test measures how thick the grease is inside a kitchen extract system. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. From the numbers, you can see whether cleaning is due. The work covers deposit thickness tests, post-clean checks and wet film thickness tests, and people most often call us about kitchens whose menu or hours have changed and sites with gaps in their extract records.

Work in a small place like Whempstead 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.

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.

How we price TR19 inspection

Before we fix a price, we need to know a few things. We check:

  • The times the site is available
  • The scale of the work
  • Whether it’s a one-off visit or part of a schedule
  • Where the site is and how we reach it

We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.

What we need to know

To help us quote quickly, please include:

  • When the site is open and when it’s quiet
  • The postcode and the type of business
  • Detail shots of panels, filters and grilles
  • The paperwork from the last visit, if you have it

Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.

TR19 inspection around Whempstead

The Food Standards Agency lists about 4 pubs, bars and clubs as registered food businesses within about 1.5 miles of central Whempstead. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Environmental health officers from East Hertfordshire council inspect food businesses in Whempstead. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked. Hertfordshire Fire and Rescue Service covers Whempstead. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

If you run a church or community hall kitchen, near Parish Church of All Saints or elsewhere in Whempstead, its extract still collects grease from every lunch and event. If you look after a school kitchen, at a school such as Munden Church of England Voluntary Controlled Primary School or anywhere near Whempstead, the holidays are the usual time for a TR19® clean.

Why it’s worth doing now in Whempstead

Without readings, you are guessing when to clean. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, which you won’t know without measuring. In a small place like Whempstead, a system that fails can take a site out of use.

When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before work begins.

Whempstead: your questions answered

Which environmental health team covers Whempstead?

Kitchens in Whempstead are inspected by East Hertfordshire council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

Is Whempstead within the area you cover?

Yes, Whempstead is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.

What should I send you?

The site address, the type of premises and your opening hours, along with a few pictures and any previous report.

How much does TR19 inspection cost in Whempstead?

Size, condition, access and working hours all affect the cost. Call for a fixed quote, usually ready within one working day.

Can you price the work without visiting?

Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.

Can you set up regular visits?

Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.

What is a WFTT or DTT grease test?

WFTT and DTT are the two methods for measuring grease thickness, in microns. We take readings at set points from canopy to fan.

What does TR19 mean?

TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

What happens on the day

There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. For a village or hamlet like Whempstead, tell us about narrow lanes, gates and parking when you book.

  1. We go through any past certificates and reports.
  2. We follow the extract from canopy to discharge.
  3. We note where access panels are and where more are needed.
  4. Grease readings are taken and pictures recorded.
  5. You get a report and a fixed quote for the clean.

Preparing for the visit

  • Tell us about site rules, permits or sign-in
  • Make sure equipment near the work can be switched off and left to cool
  • Find the previous report, if there is one

Ask for a quote

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

For landlords and multi-site operators

Facilities teams in offices, schools and healthcare sites book us too in Whempstead and across Hertfordshire. Larger estates can be phased building by building around the people who use them.

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.

What TR19 inspection can’t fix

We’ll always give you a straight diagnosis, so here’s what this work cannot put right:

  • Parts of the duct nobody can reach yet
  • Fire safety duties beyond the extract system
  • Fan breakdowns, which need a repair visit

If in doubt, ring 0345 646 2711 or drop us a line and we will say what we think before booking.

Where we work

  • Pre-clean surveys
  • Wet film thickness tests
  • Access surveys
  • Deposit thickness tests
  • Post-clean checks
  • Insurer audits

Common problems we fix in Whempstead

Grease in a duct is flammable fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Measuring it is the first step to keeping it under control.

Keep an eye out for these warning signs:

  • Heavy grease suspected in the plenum or ducts
  • Kitchens taken over with no cleaning records
  • Insurance renewals needing proof of TR19 cleaning
  • Uncertainty over how often to clean

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hertford County Hospital is the nearest hospital to Whempstead, about 5.4 miles south.
