About our TR19 inspection in Gubblecote

Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. 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. If you are dealing with uncertainty over how often to clean and missing access panels found on survey, we can put it right, from insurer audits, pre-clean surveys and deposit thickness tests onwards.

Somewhere as small as Gubblecote, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.

Every visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What a clean will not put right

We’d rather tell you now than book work that will not help, so here are the limits:

  • Parts of the duct nobody can reach yet
  • A faulty or failing extract fan
  • The responsible person’s own fire risk assessment

If in doubt, call 0345 646 2711, or send details by email and we will say what we think before you book.

What the work covers

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

Leave it or put it right?

Sites in Gubblecote that have never measured grease cannot tell whether their cleaning interval suits the kitchen. Testing gives you the evidence to set it properly. It’s simpler to plan the work at Gubblecote now than to arrange it in a hurry later.

What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

FAQs for Gubblecote

Do you work overnight in Gubblecote?

Yes, we can come after you close and finish before you open. The work in Gubblecote can fit around your hours. Just call 0345 646 2711 or send us an email with your opening times and we will plan around them.

Who is the fire and rescue service for Gubblecote?

That’s Hertfordshire Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.

Do you work with multi-site operators?

Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.

Can we book visits on a schedule?

Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.

When should we have our next grease test?

That varies with the kitchen’s daily use. BESA sets minimum cleaning intervals of 3, 6 or 12 months by daily use, and testing shows if your kitchen needs more.

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

We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.

Why survey before a clean?

A survey finds out how the system is laid out, how dirty it is and what can be reached, so the clean goes to plan. Missing access panels are noted so they can be sorted first.

What do you do with what you remove?

Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.

TR19 inspection around Gubblecote

Food Standards Agency records include about 4 pubs, bars and clubs within roughly a mile and a half of the centre of Gubblecote. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. It’s Dacorum council that sends environmental health officers to food businesses in Gubblecote. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after. Gubblecote sits within the area of Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.

If you look after a school kitchen, at a school such as Long Marston VA Church of England Primary School or anywhere near Gubblecote, the holidays are the usual time for a TR19® clean.

The process

On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Seeing the system in pictures first means the trip to Gubblecote can be planned properly.

  1. First we book a time that won’t disrupt cooking.
  2. Every part of the system is examined, end to end.
  3. Grease readings are taken at set points using WFTT or DTT.
  4. We photograph the test points and record any sections we cannot reach.
  5. We send a report setting out the readings, photos and next steps.

How to prepare

  • Make sure equipment near the work can be switched off and left to cool
  • Clear the space around the work
  • Arrange a key holder or contact on site

Aftercare tips

Results last longer with the right care. We suggest:

  • Keep to the recommended interval
  • Clean grease off the canopy between professional cleans
  • Store grease readings where your insurer can see them
  • Keep the route to access panels clear

The report recommends when the system should next be cleaned and tested, based on the readings and how the kitchen is used.

Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.

Fixed quotes for TR19 inspection in Gubblecote

Sites vary more than people expect. What affects the quote:

  • The condition we find in the survey
  • The size of the system
  • When the work can happen, such as evenings, overnight or weekends
  • Any permits to work or inductions

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

What to send for a quote

Before you ask for a quote, gather:

  • Close-ups of filters, grilles, hatches or access panels
  • Your opening hours and when the area is out of use
  • A few general shots of the system
  • Problems your staff have spotted

Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

When to call us in Gubblecote

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. Knowing how much there is lets you act before it becomes a hazard.

It’s time to book a visit if you see:

  • Systems cleaned on a calendar with no measurements
  • Insurers asking for TR19 evidence
  • Extracts that may be over the 200 micron mean
  • Surveys needed before quoting a full clean

Ascott House, about 4.8 miles north, is one of the historic houses near Gubblecote; if you run event catering at a venue like that, cleans can be booked between functions.

Questions to ask before booking

  • Whether the quote shows VAT
  • What insurance they carry
  • Whether a survey comes first
  • Whether the figure could change on the day

Restaurants, pubs and hotels

Inspections are done when the kitchen is closed or quiet so trading is not affected.

Canopy and plenum

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