TR19 inspection for sites in River

How we handle TR19 inspection in River

A grease test measures how thick the grease is inside a kitchen extract system. 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. If you have sections of duct that can’t be reached and kitchen extract systems with no recent grease readings, we can help.

In a small place like River, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.

Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Leave it or put it right?

Post-clean verification shows whether the system was left the way the certificate says, while there’s still time to put anything right. Somewhere as small as River, losing a kitchen or building to a fault is felt by everyone who uses it.

The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before work begins.

Why us?

  • Fixed quotes from a survey or photos
  • Work around your opening hours, with 24/7 emergency cover
  • Fully insured
  • A single point of contact for sites across the South East and London

What we do, step by step

Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a morning or less for one kitchen, more where there are several systems. We agree a date with you, plan the drive to River and turn up when the site is quiet.

  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. Grease readings are taken and photos recorded.
  5. We report back with readings and a fixed quote.

Before we arrive

  • Tell us about site rules, permits or sign-in
  • Name a contact who can let us in at the agreed time
  • Have your last certificate or report to hand

Get a fixed quote

To get a fixed quote, give us a ring on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You’ll usually have a quote within one working day.

Advice

For landlords and multi-site operators

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 the report can go to both.

From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.

What your team can do, and what needs us

A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

When it’s something else

It’s worth knowing the limits before booking:

  • Fan breakdowns, which need a repair visit
  • Heavy deposits found on test, which still need cleaning
  • Design faults in the extract system

Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we’ll tell you honestly.

Parts of the system we cover

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

What we’re called out for in River

Not every section of a kitchen extract is easy to get to, so those sections can be skipped time and again. An inspection of a system in River shows where access panels are missing, so the gaps can be closed.

The symptoms we are asked about most include:

  • Parts of the system left out of past cleans
  • An insurer’s request for a TR19 audit
  • Uncertainty over how often to clean
  • Post-clean verification after another contractor’s clean

Volunteers running a hall kitchen near The Parish Church of St Peter, or anywhere in River, may not know when the extract was last cleaned, and a grease test settles it.

Questions to ask before booking

  • If the quote is a fixed price or an estimate
  • If they look at the system before pricing
  • How they set the interval to the next visit
  • How areas they cannot reach will be recorded

How to choose an extract cleaning contractor

Kitchen extracts in River

According to Food Standards Agency records, there are about 3 bars, pubs and nightclubs within about 1.5 miles of central River. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. The fire and rescue service for River is West Sussex 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 River, food businesses are inspected by environmental health officers from Chichester council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand.

If you run catering at a historic house or estate in the area (Petworth House is about 2.4 miles east), event kitchens in older buildings often have awkward duct runs that need planning. Healthcare kitchens, like those at hospitals such as Midhurst Community Hospital (about 3.2 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands.

River is about 12 miles east of Petersfield, in West Sussex. River 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. Our area takes in 371 places across West Sussex, from busy centres to quieter spots. There’s also a page for Guildford, about 17 miles away.

Every address in GU28 is within our area for TR19 inspection, from the main roads to the quietest streets. Close by, we work in Upperton (1 mile east), Selham (2 miles south), Tillington (2 miles south-east), South Ambersham (2 miles south-west) and Hampers Green (2 miles east). We also work in nearby towns such as Bognor Regis (14 miles south), Chichester (12 miles south-west), Littlehampton (14 miles south-east), Rustington (15 miles south-east), Storrington (11 miles south-east) and Billingshurst (9 miles east).

Near you in River

We work in commercial kitchens and buildings around The Hollist Arms Public House, among other places. A little further out are Lodsworth Castle (1.3 miles south) and Coultershaw Heritage Site (3 miles south-east). Not far away are Graffham Common and Blackdown.

River questions

Will you come out to River?

Yes, we work in villages as well as towns, and River is covered. Just mention lanes, gates or anything else about the site when you book.

Do you work at weekends in River?

Yes, evening, overnight and weekend work is normal for us. That way a site in River doesn’t have to lose a day’s trading. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.

What should I send you?

A short description and a few pictures plus the address and your hours. If we need more, we’ll ask.

What happens on a pre-clean survey?

We survey, measure and photograph the system first. We can work from photos and details, or visit, as suits the job.

What’s TR19?

BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.

Can you inspect our extract for our insurance company?

Yes. Our TR19 audits cover readings, photos, access and a recommended cleaning interval. You can pass it straight to your insurer or broker.

What do you do to protect the area?

We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.

At what point does grease need cleaning?

TR19® Grease says grease should not go over a mean of 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.

Looking after it afterwards

So the system stays in good health:

  • Keep the route to access panels clear
  • Flag changes in how much frying the kitchen does
  • Store grease readings where your insurer can see them
  • Diary the next grease test and clean

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

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