TR19 inspection in Marylebone

Not every kitchen fits neatly into a calendar. In a busy kitchen, grease can build faster than the minimum intervals allow for, which is why measurement matters. We give your risk assessment measured figures rather than guesses. Typical jobs include kitchens whose menu or hours have changed and kitchen extract systems with no recent grease readings, across insurer audits, access surveys and post-clean checks.

In a London area like Marylebone, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.

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.

Leave it or put it right?

Surveying first means the clean goes to plan. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, so the clean covers the whole system. Leaving it on a busy London site only adds to the work.

We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

Part by part

Extract fan and discharge

Grease builds up on the fan blades and inside the housing. They’re included in the readings and photos.

Vertical risers

Access to risers is often limited. The survey shows exactly what access there is.

Fixed quotes for TR19 inspection in Marylebone

Some jobs are bigger than they look, and some smaller. The main factors:

  • Working hours and out-of-hours timing
  • Whether we need access equipment or extra panels
  • Travel, parking and unloading
  • The condition of the system

One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before any work starts.

Helping us quote

We can often survey from pictures. Try to include:

  • Photos showing the whole system and its surroundings
  • Your last certificate, test record or report
  • Detail shots of panels, filters and grilles
  • Your opening hours and when the area is out of use

We do not publish a price list, because every site is different. We look at your system first, from photos or on a visit, and then send you a fixed quote. To start, give us a ring on 0345 646 2711 or use the quote form.

FAQs for Marylebone

Which fire and rescue service is responsible for Marylebone?

That’s London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Do you clean school canteen extracts around Marylebone out of term?

Yes. The holidays are the usual time for school work. With about 80 schools and colleges on the FSA’s register within roughly a mile and a half of Marylebone, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.

What do you need from me for a quote?

Some pictures and a quick description of the system plus the address and your hours. If we need more, we’ll ask.

What is a WFTT or DTT grease test?

It’s a measurement of how much grease is coating the inside of the extract, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). The results are given in microns.

What happens to the waste?

We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.

How long does grease testing take?

As a guide, it takes around an hour or two per canopy and duct system. The size of the system and the access make the difference.

Do you offer emergency callouts?

Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.

Which accreditations do you hold?

We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Looking after it afterwards

So the system stays in good health:

  • Mention new equipment or longer hours at the next test
  • Keep grease filters clean and fitted properly
  • Have the latest report ready for insurance renewals
  • Report grease dripping from the canopy

After the inspection, we send a report showing each reading, its location and photos. File it alongside your TR19 certificates.

Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.

Do you need TR19 inspection in Marylebone?

Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Measuring it is the first step to keeping it under control.

Clients usually contact us when they notice something like this:

  • Missing access panels found on survey
  • Heavy grease suspected in the plenum or ducts
  • Surveys needed before quoting a full clean
  • Missing TR19 certificates or history

Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Marylebone is Respiratory Clinical Trials, about under half a mile north.

What to look for in a quote

  • When they can work, and whether that is outside your opening hours
  • Whether a survey comes first
  • When the next visit should be, and why
  • Exactly which parts of the system are covered

Our hiring checklist

Kitchen extracts in Marylebone

Food Standards Agency records list about 3,845 restaurants, cafés and works canteens and about 393 takeaways within 1.5 miles or so of the middle of Marylebone. Each kitchen extract among them can be measured for grease to set the right cleaning interval. London Fire Brigade covers Marylebone. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Overnight is the normal time to clean a London kitchen extract, so trading is not affected.

Where a hall near Russian chapel on Welbeck Street, or anywhere in Marylebone, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Term dates shape school work: for a school like St Vincent's Catholic Primary School, an extract clean fits neatly into a half-term or summer break.

For landlords and multi-site operators

We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.

We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

How it works

There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes around an hour or two per canopy and duct system. Before any visit in Marylebone, we agree where the van can stop and how equipment reaches the system.

  1. After the clean, we arrange a time to check the system.
  2. The same access points are opened up.
  3. Grease readings are taken again at set points.
  4. Photos are taken to show the condition after the clean.
  5. We report the findings and flag any areas that need more work.

Preparing for the visit

  • Plan for cooking equipment or plant to be off before we arrive
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Dig out any earlier paperwork for the system

Getting a quote

To help us quote: where the site is, what it is and its opening hours, a few pictures and any previous report or certificate. Then call 0345 646 2711, or email photos.
