TR19 inspection near Henton

What we’re called out for in Henton

Looking at a canopy tells you little about what’s in the duct. Clean filters can hide a heavy layer behind them, so readings are the reliable guide.

What we’re most often called out for:

  • Pre-clean surveys before a first TR19 clean
  • Extracts that have never been grease tested
  • Cleaning intervals that may not suit the kitchen
  • Insurers asking for TR19 evidence

Where a hall near Church of the Holy Trinity, or anywhere in Henton, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What to look for in a quote

  • Whether they’re fully insured
  • What happens if part of the system can’t be accessed
  • Whether the whole system is included, or only the parts that are easy to reach
  • How VAT is shown on the quote

Choosing a duct cleaning contractor

TR19 inspection in Henton, done properly

A grease test measures how thick the grease is inside a kitchen extract system. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. The results show whether the system needs cleaning and how soon. The work covers deposit thickness tests, access surveys and post-clean checks, and the jobs we see most are post-clean verification after another contractor’s clean and kitchens taken over with no cleaning records.

In a village or hamlet like Henton, 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, whatever the size of the place.

Every visit ends with a written report and photos, 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.

Managing agents and facilities teams in Henton

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

For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.

What the work involves, part by part

Restaurants, pubs and hotels

BESA’s minimum for heavy use of 12 to 16 hours a day is a clean every 3 months, and readings show whether that’s enough.

Schools, hospitals and care homes

Hospital and care home kitchens can cook all day, every day. Testing shows if the cleaning interval keeps pace.

What affects the quote in Henton

The quote reflects the site in front of us. We take into account:

  • Working hours and out-of-hours timing
  • The condition of the system
  • Access, including roofs, risers and ceiling voids
  • Travel, parking and unloading

Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, ring 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.

Asking for a quote

A few details help us quote accurately. With your enquiry, please include:

  • Where the site is and what kind of site it is
  • Problems your staff have spotted
  • Any previous report or certificate
  • How we’d reach plant on a roof or in a plant room

For a fixed quote, call us on 0345 646 2711 or email us 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. We typically come back within one working day.

Honest limits

To be straight with you, there are a few things this work won’t fix:

  • A faulty or failing extract fan
  • Removing the grease, which is a separate clean
  • Installation problems, which fall under design guidance such as DW172

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

What the work covers

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

Henton kitchens: local notes

Food Standards Agency data counts about 3 restaurants, cafés and works canteens within about 1.5 miles of central Henton. For any of them with a canopy, measuring grease is better than guessing when to clean. It’s South Oxfordshire council that sends environmental health officers to food businesses in Henton. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Henton falls to Oxfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.

Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Adwell House is about 4.6 miles south-west), access may need planning. A hospital like Thame Community Hospital, about 3.6 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Henton is about 4 miles south-east of Thame, in Oxfordshire. Whatever kind of site you run in Henton, we can take on TR19 inspection. Visits can be booked for evenings, overnight or weekends so trading isn’t interrupted. Our area takes in 443 places across Oxfordshire, large and small. We also work in Oxford, about 15 miles from Henton.

We cover every part of the OX39 postcode area for TR19 inspection and the roads nearby. Whether your site is on Manor Farm Way and New Close Farm Road or a nearby road, we can help. We also cover the places around Henton: Forty Green (1 mile north), Skittle Green (1 mile east), Holly Green (1 mile north-east), Pitch Green (1 mile east) and Bledlow (1 mile east). Further out, we also cover Oxford (15 miles west), Thame (4 miles north-west), Henley-on-Thames (13 miles south), Benson (11 miles south-west), Headington Quarry (13 miles west) and Wallingford (13 miles south-west).

The process

There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, which takes a morning or less for one kitchen, more where there are several systems. Somewhere as small as Henton, the date and timings are agreed with you well before the day.

  1. After the clean, we arrange a time to check the system.
  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.

How to prepare

  • Tell us about site rules, permits or sign-in
  • Let us know about parking and loading
  • Have your last certificate or report to hand

How to get a quote

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Common questions in Henton

Who is the fire and rescue service for Henton?

Henton is in the area of Oxfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Can the work in Henton be done at night or at weekends?

Yes, nights and weekends are routine for us. The site is handed back ready to open. Just give us a ring on 0345 646 2711 or drop us a line with your opening times and we will plan around them.

How much notice should we give?

Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.

Can you price the work without visiting?

Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.

What is grease thickness testing?

Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, and set against the TR19® Grease figures.

What information do you need?

The site address, the type of premises and your opening hours, along with a few photos and any previous report.

Can we book visits on a schedule?

Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.

Can you look after several sites?

Yes. You deal with one contact for every site in our area, with visits on a regular schedule.

Staff cleaning versus specialist work

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.

A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
