TR19 inspection for sites in North Aston

TR19 inspection for kitchens and businesses in North Aston

A pre-clean survey is the diagnosis, and the clean is the treatment. Readings, photos and notes on access are gathered from end to end, so the clean can be planned properly. Common call-outs are for pre-clean surveys before a first TR19 clean and sites with gaps in their extract records, on deposit thickness tests, wet film thickness tests and pre-clean surveys.

In a village or hamlet like North Aston, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.

The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Kitchen extracts in North Aston

Oxfordshire Fire and Rescue Service covers North Aston. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. In North Aston, food businesses are inspected by environmental health officers from Cherwell council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

If you run a church or community hall kitchen, near Church of St Mary or elsewhere in North Aston, its extract still collects grease from every lunch and event.

Questions from North Aston

Which fire and rescue service is responsible for North Aston?

North Aston is in the area of Oxfordshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

Can you get to a site in North Aston?

Yes. Villages and rural sites across the South East are part of our work, North Aston included. The journey is planned ahead, so a few details about the route help.

Can the work be done while we’re closed?

Yes, and it’s often the best time. The visit is timed for when the area isn’t in use, whether that is late evening, overnight or a weekend.

What’s TR19?

BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.

How do you protect the area?

Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.

How long does grease testing take?

Typically, the inspection takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. The size of the system and the access make the difference.

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 is a WFTT or DTT grease test?

It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. The results are given in microns.

Why act early in North Aston

Without readings, you’re guessing when to clean. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, and you can only act on that if you’ve measured it. With notice, the visit to North Aston can be fitted around your bookings and events.

Keeping the system healthy

Looking after the system between visits is straightforward, and it helps at the next visit:

  • Report grease dripping from the canopy
  • Store grease readings where your insurer can see them
  • Wipe the canopy surfaces regularly
  • Keep to the recommended interval

Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can quote to do it.

Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.

Part by part

Restaurants, pubs and hotels

We test between services, early in the morning or after close so the kitchen keeps cooking.

Canopy and plenum

The canopy itself is checked inside and out, and note where grease has gathered.

Signs you need TR19 inspection in North Aston

Grease is 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. Measuring it is the first step to keeping it under control.

Look out for these warning signs:

  • Cleaning intervals that may not suit the kitchen
  • Systems that need surveying before cleaning
  • Missing access panels found on survey
  • Heavy grease suspected in the plenum or ducts

Whether the kitchen is in North Aston itself or nearby, a TR19® clean covers the whole system, canopy to discharge.

Choosing a duct cleaning contractor

Managing agents and facilities teams in North Aston

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.

Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.

In-house cleaning or a specialist?

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.

The process

Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the TR19 inspection, tidy up and hand over the paperwork. The visit itself takes a morning or less for one kitchen, more where there are several systems. Visits to a village like North Aston are booked in advance, at a time that suits whoever runs the site.

  1. First we look at the system’s cleaning history, if there is one.
  2. We follow the extract from canopy to discharge.
  3. We note where access panels are and where more are needed.
  4. Grease readings are taken and photos recorded.
  5. We report back with readings and a fixed quote.

Getting ready for the visit

  • Mention any sign-in, permit or induction we need
  • Move anything stored near the system
  • Let us know when the site is closed or quiet

Ask for a quote

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, phone us on 0345 646 2711 or send us an email.
