TR19 inspection across Cranford

TR19 inspection for kitchens and businesses in Cranford

Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). The results show whether the system needs cleaning and how soon. Typical jobs include sections of duct that can’t be reached and confirming a clean reached the whole system, across wet film thickness tests, pre-clean surveys and post-clean checks.

In a London area like Cranford, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.

The paperwork matters as much as the work. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Landlords, agents and facilities managers

Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.

What staff can safely do

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

FAQs for Cranford

Which fire and rescue service is responsible for Cranford?

London Fire Brigade is the fire and rescue service for Cranford. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Do you work overnight in Cranford?

Yes, we can come after you close and finish before you open. The work in Cranford can fit around your hours. Your opening times are the first thing we ask for.

What happens if you cannot reach some of it?

Anything we can’t reach goes on the report, with photos where possible, and we explain what access is needed, for example new access panels.

What do you do to protect the area?

Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.

Can we book visits on a schedule?

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

How much time does an inspection need?

It takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. The visit is timed so cooking is not disrupted.

What accreditations do you have?

We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

How much notice should we give?

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

TR19 inspection in Cranford: the local picture

Look up Cranford on the FSA’s food hygiene register and you’ll find about 98 restaurants, cafés and canteens and about 48 sandwich bars and takeaways across Cranford and its immediate surroundings (about a mile and a half). Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Environmental health officers from Hounslow council inspect food businesses in Cranford. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand.

Healthcare kitchens, like those at hospitals such as Hounslow Hospital (about 1.6 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands. Term dates shape school work: for a school like Cranford Primary School, an extract clean fits neatly into a half-term or summer break.

Cranford is about 2 miles north of Feltham, in Greater London. Cranford gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with photos.

What a clean won’t put right

We’d rather tell you now than book work that will not help, so these are the things it won’t cover:

  • Design faults in the extract system
  • Heavy deposits found on test, which still need cleaning
  • The responsible person’s own fire risk assessment

If you’re not sure, just call 0345 646 2711 or send us an email and we’ll give you a straight answer before you book.

What we work on in Cranford

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

When to call us in Cranford

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.

These are the problems we see most often:

  • Systems that need surveying before cleaning
  • Missing access panels found on survey
  • Insurers asking for TR19 evidence
  • Systems cleaned on a calendar with no measurements

Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Osterley House is about 2.6 miles east), access may need planning.

Questions to ask before booking

How it works

Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes a couple of hours for a typical kitchen extract system. Night and weekend working is normal for us in London, and a site in Cranford is no exception.

  1. After the clean, we arrange a time to check the system.
  2. We open the access points used on the clean.
  3. Grease readings are taken again at set points.
  4. We photograph each area to record how it was left.
  5. The results are reported, with anything missed flagged.

Preparing for the visit

  • Clear the space around the work
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Allow time for equipment near the work to be turned off and cool down

To help us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711 or send us an email.

Advice

Leave it or put it right?

After an incident, an insurer can ask to see proof of TR19 cleaning and inspection. Missing records can put a claim at risk. An up-to-date inspection report is a good place to start. Leaving it on a busy London site only adds to the work.

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 work begins.

Why book with us

  • Out-of-hours work and a 24/7 emergency line
  • Ventilation hygiene specialists since 2009
  • Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease
  • Accredited under CHAS and SafeContractor, with ISO 9001

Fixed quotes for TR19 inspection in Cranford

Your quote is based on your site. We take into account:

  • The times the site is available
  • Site rules, permits and inductions
  • Whether we need access equipment or extra panels
  • The number of sites or systems

Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, phone us on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.

Asking for a quote

When you contact us, it’s useful to have:

  • Any access panels or hatches you can see
  • Your opening hours and when the area is out of use
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
