TR19 inspection near Bulstrode

TR19 inspection for kitchens and businesses in Bulstrode

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, access surveys and insurer audits, and common reasons people get in touch are systems that need surveying before cleaning and confirming a clean reached the whole system.

Somewhere as small as Bulstrode, 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, whatever the size of the place.

Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the job changes from site to site

Restaurants, pubs and hotels

Inspections are done when the kitchen is closed or quiet so the kitchen keeps cooking.

Extract fan and discharge

A greasy fan works harder and wears faster. The inspection shows whether it needs cleaning now.

What happens on the day

Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes a morning or less for one kitchen, more where there are several systems. The timing of a visit to Bulstrode is set by you, and the travel is our side of the planning.

  1. First we look at the system’s cleaning history, if there is one.
  2. The layout is traced from the canopy to the discharge.
  3. Access panels are located and any missing ones noted.
  4. We measure the grease and photograph each point.
  5. You get a report and a fixed quote for the clean.

Preparing for the visit

  • Mention any parking or loading restrictions
  • Make sure someone can let us in and lock up afterwards
  • Agree a time when the area can be out of use

Advice

For landlords and multi-site operators

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.

For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.

Common problems we fix in Bulstrode

Records can go missing when a business changes hands or contractors. With no history, the current state of the extract is a guess.

Keep an eye out for any of the following:

  • Surveys needed before quoting a full clean
  • Uncertainty over how often to clean
  • Sections of duct that cannot be reached
  • Ductwork where grease may be over the TR19 limits

Historic houses near Bulstrode, such as Chenies Manor House about 3 miles south, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Questions to ask before booking

  • What paperwork you get at the end
  • Exactly which parts of the system are covered
  • Which accreditations they hold, and whether you can check them
  • Proof of insurance

Our hiring checklist

Grease, kitchens and Bulstrode

Food Standards Agency records list about 9 cafés, restaurants and staff canteens in Bulstrode and the streets around it, up to about 1.5 miles out. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Bulstrode is covered by Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. In Bulstrode, food businesses are inspected by environmental health officers from Dacorum council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.

Where a hall near Church of St Lawrence, or anywhere in Bulstrode, hosts lunch clubs or events, its extract gathers grease just as a café’s does. For schools such as Bovingdon Primary Academy, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

Questions from Bulstrode

Who would carry out a food hygiene inspection at a kitchen in Bulstrode?

That’s Dacorum council, whose environmental health officers carry out food hygiene inspections in Bulstrode. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

Will you come out to Bulstrode?

Yes. Villages and rural sites across the South East are part of our work, Bulstrode included. Just mention lanes, gates or anything else about the site when you book.

What is post-clean verification?

It’s an inspection after cleaning, to show what state the system was left in, for our cleans and other firms’ alike.

What happens to the waste?

We take it away at the end of the visit. While we work, it’s kept contained so the area stays clean.

What does TR19 inspection cost?

There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before we start.

How much notice do you need?

Earlier is better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.

Can you inspect our extract for our insurance company?

Yes. Insurers often want evidence the extract is managed to TR19®, and an audit report gives you that, along with any actions needed.

What accreditations do you have?

Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.

Why it’s worth doing now in Bulstrode

Sites in Bulstrode that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Testing gives you the evidence to set it properly. In a small place like Bulstrode, a system that fails can take a site out of use.

A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.

Why Bulstrode businesses choose us

  • Evenings, overnight and weekends, plus 24/7 emergency callout
  • A single point of contact for sites across the South East and London
  • We’re fully insured
  • Fixed quotes from a survey or pictures

Staff cleaning versus specialist work

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.

Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.

Between visits

How long the results last depends on use and care. Here’s what we suggest:

  • Keep TR19 certificates, readings and reports together
  • Send TR19 audit reports to your insurer on request
  • Clean grease off the canopy between professional cleans
  • Book the next test on the date in the report

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

Keep filters clean and in place. Gaps around filters let grease get past them.
