TR19 inspection in Cassington

Multi-site and managed buildings

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.

We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Work can be phased by floor, building or site around the people who use them.

How we handle TR19 inspection in Cassington

Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Testing is how you know where your system stands. We’re often asked to deal with extracts that have never been grease tested and checking the result of a recent clean, across access surveys, pre-clean surveys and wet film thickness tests.

Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.

The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

How the visit works

When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes an hour or two for a single kitchen, longer for a large or complex system. If you can send photos, we can arrive in Cassington knowing what to expect.

  1. Post-clean verification is booked once the clean is done.
  2. We open the access points used on the clean.
  3. Grease readings are taken again at set points.
  4. Photos are taken to show the condition after the clean.
  5. The results are reported, with anything missed flagged.

Before we arrive

  • Dig out any earlier paperwork for the system
  • Plan for cooking equipment or plant to be off before we arrive
  • Mention any locked doors, roof access or ceiling voids

Advice

How we price TR19 inspection

Your quote is based on your site. We consider:

  • One-off work versus a regular cycle
  • Any permits to work or inductions
  • The condition we find in the survey
  • Working hours and out-of-hours timing

We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.

Asking for a quote

When you call or email, these details help:

  • Wide pictures of the system and the area around it
  • Your opening hours and when the area is out of use
  • The paperwork from the last visit, if you have it
  • Where the plant sits or the system leaves the building, such as a roof or outside wall

Want a quote for TR19 inspection? Please call 0345 646 2711 or email us and tell us about the site. We will explain what we’d do and send a fixed quote before anything is booked.

Signs you need TR19 inspection in Cassington

Kitchens change: a new menu, longer hours or more frying can all add grease. The old cleaning schedule may not match the kitchen any more.

The symptoms we’re asked about most are:

  • Checking the result of a recent clean
  • Sections of duct that cannot be reached
  • Insurance renewals needing proof of TR19 cleaning
  • Pre-clean surveys before a first TR19 clean

Bursars and site managers at schools such as St Peter's Church of England Primary School tend to book extract cleaning for when the kitchen is empty.

What your quote should include

  • When they can work, and whether that is outside your opening hours
  • Whether they recommend a next date
  • Whether inaccessible sections are listed on the report
  • Proof of accreditation you can verify

Choosing a duct cleaning contractor

Cassington kitchens: local notes

Look up Cassington on the FSA’s food hygiene register and you’ll find about 4 restaurants, cafés and canteens within roughly a mile and a half of the centre of Cassington. For any of them with a canopy, measuring grease is better than guessing when to clean. Kitchens in Cassington get their food hygiene inspections from West Oxfordshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for Cassington is Oxfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.

If you run catering at a healthcare site, such as a hospital like Radcliffe Infirmary about 4.1 miles south-east, the extract may need cleaning more often than a part-time kitchen. Volunteers running a hall kitchen near Church of St Peter, or anywhere in Cassington, may not know when the extract was last cleaned, and a grease test settles it.

Cassington is about 6 miles north-west of Oxford, in Oxfordshire.

What a clean will not put right

In fairness, there are a few things this work won’t fix:

  • Removing the grease, which is a separate clean
  • Fan breakdowns, which need a repair visit
  • Sections with no access, until panels are fitted

If you’re not sure, just give us a ring on 0345 646 2711 or drop us a line and we’ll give you a straight answer.

What the work covers

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

Between visits

Aftercare is simple, and it helps at the next visit:

  • Wipe the canopy surfaces regularly
  • Flag changes in how much frying the kitchen does
  • Have the latest report ready for insurance renewals
  • Keep grease filters clean and fitted properly

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

Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.

What staff can safely do

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.

Questions from Cassington

Who is the fire and rescue service for Cassington?

Oxfordshire Fire and Rescue Service is the fire and rescue service for Cassington. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Can you clean school kitchen extracts in Cassington during the holidays?

Yes. The holidays are the usual time for school work. Around Cassington, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.

Do you survey before quoting?

Yes. We always survey first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.

What types of premises do you cover?

All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.

What do the grease readings need to be?

The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. Our report sets your readings against both.

How much does TR19 inspection cost?

Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll typically reply within one working day.

Do you check other contractors’ cleans?

Verification means repeat readings and photos once the clean is done. Any areas that weren’t cleaned properly are flagged.

Can you come out in an emergency?

Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
