TR19 inspection for sites in Whitfield

TR19 inspection in Whitfield

BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Those are minimums, and grease readings help set the real interval. The work covers deposit thickness tests, post-clean checks and wet film thickness tests, and the jobs we see most are post-clean verification after another contractor’s clean and heavy grease suspected in the plenum or ducts.

Kitchens around a place like Whitfield are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.

A written report with pictures follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Leave it or put it right?

A check after cleaning shows whether the work reached every part it should have, before the next clean is due. In a smaller place like Whitfield, a site that has to close is felt quickly.

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’ll explain what it covers.

What we’re called out for in Whitfield

Kitchens change: a new menu, longer hours or more frying can all add grease. A cleaning interval set years ago may no longer fit.

What we’re most often called out for:

  • Missing TR19 certificates or history
  • Insurance renewals needing proof of TR19 cleaning
  • Checking the result of a recent clean
  • Extracts that have never been grease tested

Healthcare kitchens, like those at hospitals such as Buckland Hospital (about 1.9 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.

Questions to ask before you book

  • Whether the quote shows VAT
  • Whether a written report and pictures are included
  • What’s included in the scope, part by part
  • Whether the price is fixed

What TR19 inspection looks like in Whitfield

The coast is only about 3 miles from Whitfield. Corrosion on the fan housing and cowl is worth a look at every clean, alongside the grease. Look up Whitfield on the FSA’s food hygiene register and you will find about 10 cafés, restaurants and staff canteens and about 8 sandwich bars and takeaways in and around Whitfield, up to about a mile and a half out. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. Kitchens in Whitfield get their food hygiene inspections from Dover council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.

For schools such as Whitfield Aspen School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Church and community hall kitchens, near Church of St Peter or anywhere around Whitfield, are easy to forget, but their extracts collect grease like any other.

Looking after it afterwards

Results last longer with the right care. We suggest:

  • Keep canopy edges and gutters wiped down
  • Never cook with filters missing
  • File every inspection report with your certificates
  • Share inspection reports with your insurer or broker when asked

For an insurer audit, send them the report as it is, with readings, photos and any areas not accessible.

Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.

FAQs for Whitfield

Who inspects food businesses in Whitfield?

The local authority for Whitfield is Dover council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Is TR19 inspection any different in a coastal place like Whitfield?

It can, as Whitfield is within about 3 miles of the sea, where salt in the air is hard on metal. We look at fans, cowls and fixings for rust as well as grease.

How long does grease testing take?

Testing takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Sites with several canopies take longer, and you can phone us on 0345 646 2711 or send us an email to book it in.

Can you look after several sites?

Yes. Tell us the addresses and what each needs and we will quote them together.

Can you inspect our extract for our insurance company?

Yes, anywhere in the area we cover. Share the insurer’s request so the report addresses it.

Can you price the work without visiting?

Often, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.

How do you measure grease in a kitchen extract?

Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. Each reading is recorded in microns.

How much notice should we give?

The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.

Honest limits

It’s worth knowing the limits before booking:

  • Design faults in the extract system
  • Parts of the duct nobody can reach yet
  • Removing the grease, which is a separate clean

Not sure which it is? You can ring 0345 646 2711 or email us and we will tell you honestly.
