TR19 inspection for kitchens and businesses in Cowley

A fixed schedule doesn’t always match how a kitchen really cooks. Some kitchens build up grease faster than the minimum intervals assume, which is why measurement matters. Our readings give your risk assessment real numbers to work from. The work covers wet film thickness tests, insurer audits and pre-clean surveys, and common reasons people get in touch are systems that need surveying before cleaning and kitchens taken over with no cleaning records.

In a smaller place like Cowley, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. A kitchen that cooks fewer hours still builds up grease, so cleaning is planned around how much it cooks and what the readings show.

Aftercare tips

So the system stays in good health:

  • Wipe the canopy surfaces regularly
  • Keep TR19 certificates, readings and reports together
  • Send TR19 audit reports to your insurer on request
  • Keep grease filters clean and fitted properly

The audit report is set out to pass straight to your insurer or broker, with readings, photos and any areas not accessible.

Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.

How the visit works

Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes an hour or two for a single kitchen, longer for a large or complex system. In a place like Cowley, we fit the visit around your hours.

  1. Post-clean verification is booked once the clean is done.
  2. The same access points are opened up.
  3. We repeat the WFTT or DTT readings.
  4. Photos are taken to show the condition after the clean.
  5. The results are reported, with anything missed flagged.

Before we arrive

  • Agree a time when the area can be out of use
  • Clear loose items from the work area
  • Let us know about permits to work or site inductions

Advice

Grease, kitchens and Cowley

There are about 98 cafés, restaurants and staff canteens and about 32 sandwich bars and takeaways across Cowley and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. In Cowley, food businesses are inspected by environmental health officers from Oxford City council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. Oxfordshire Fire and Rescue Service covers Cowley. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

Term dates shape school work: for a school like Our Lady's Roman Catholic Primary School, an extract clean fits neatly into a half-term or summer break. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Cowley is NHS Oxfordshire Clinical Commissioning Group, about within half a mile east. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Holywell Manor is about 2.1 miles north-west), access may need planning.

Cowley is about 1 mile south-east of Oxford, in Oxfordshire. Across the OX4 area, we cover TR19 inspection for commercial sites. Our Oxfordshire coverage runs to 443 places, and Cowley is one of them.

Staff cleaning versus specialist work

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

Why act early in Cowley

Catching heavy deposits early keeps the fix small. Ignored, the layer only gets thicker. A site near Cowley that has to close at short notice is hard to cover for.

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.

Landlords, agents and facilities managers

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Larger estates can be phased building by building to keep disruption down.

What the work involves, part by part

Horizontal duct runs

If a run has no access panel, we note it so it can be fixed before the clean.

Canopy and plenum

Behind the filters, the plenum catches plenty of grease. Readings and photos are taken in the plenum as part of every survey.
