About our TR19 inspection in Bledlow

Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). From the numbers, you can see whether cleaning is due. Typical jobs include heavy grease suspected in the plenum or ducts and uncertainty over how often to clean, on wet film thickness tests, post-clean checks and insurer audits.

For a kitchen in or near Bledlow, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.

Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What a clean will not put right

Not every problem is solved by TR19 inspection, and we’ll tell you before work begins. It won’t put right:

  • Sections with no access, until panels are fitted
  • Mechanical faults in the extract
  • Heavy deposits found on test, which still need cleaning

If you are not sure, just phone us on 0345 646 2711 or send us an email and we’ll give you a straight answer before booking.

  • Access surveys
  • Pre-clean surveys
  • Deposit thickness tests

Bledlow: your questions answered

Do you cover smaller places like Bledlow?

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

Who inspects food businesses in Bledlow?

That’s Buckinghamshire council, whose environmental health officers carry out food hygiene inspections in Bledlow. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

Are you accredited?

CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we are fully insured.

What happens to the waste?

We take it away when we go. During the work, it’s contained to keep the area clean.

Do you work out of hours?

Yes. Tell us your opening hours when you ask for a quote and we’ll plan the visit around them.

What does a pre-clean survey involve?

We survey, measure and photograph the system first. The survey can be done from pictures and details or on site, whichever suits the system.

How much notice should we give?

That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.

How often should a kitchen extract be inspected?

We suggest a next test date in every report, based on the readings and how the kitchen is used. The interval should come from a competent person’s risk assessment backed by grease measurement.

For landlords and multi-site operators

If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.

Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.

Aftercare tips

How long the results last depends on use and care. Here’s what we suggest:

  • Keep the route to access panels clear
  • Have the latest report ready for insurance renewals
  • Tell us if menus or opening hours change
  • Keep grease filters clean and fitted properly

Where sections couldn’t be reached, the report says where access panels would help. Fitting them before the next clean means the whole system gets done.

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

How the visit works

Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes around an hour or two per canopy and duct system. A few pictures of the system help us make the most of a visit to a place like Bledlow.

  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. We measure the grease and photograph each point.
  5. You get a report and a fixed quote for the clean.

Getting ready for the visit

  • Clear loose items from the work area
  • Plan for cooking equipment or plant to be off before we arrive
  • Dig out any earlier paperwork for the system

Get a fixed quote

For a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You’ll usually have a quote within one working day.

Related advice

Leave it or put it right?

Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Ignored, the layer only gets thicker. Out of sight is the usual reason a rural system goes too long without attention.

Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

What affects the quote in Bledlow

Every site gets its own quote. These are the things that affect it:

  • Access, including roofs, risers and ceiling voids
  • When the work can happen, such as evenings, overnight or weekends
  • How big the system is
  • The number of sites or systems

One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.

Asking for a quote

There’s no need for technical detail. It helps if you can send:

  • The times we could work without disrupting the site
  • The site address and the type of premises
  • Problems your staff have spotted
  • Any access panels or hatches you can see

Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.

Bledlow kitchens: local notes

Bledlow sits within the area of Buckinghamshire 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. We cover Bledlow, about 37 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.

Church and community hall kitchens, near Church of the Holy Trinity or anywhere around Bledlow, are easy to forget, but their extracts collect grease like any other. Healthcare kitchens, like those at hospitals such as Thame Community Hospital (about 4.6 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

Bledlow is about 5 miles south-east of Thame, in Buckinghamshire. Whether your site is in the middle of Bledlow or further out, we cover TR19 inspection for every kind of premises, from a single unit to a large public building. Across Buckinghamshire, we cover 263 places, and Bledlow is one of them. We also work in Oxford, about 16 miles from Bledlow.

We work across the HP27 postcode area for TR19 inspection and the roads nearby. If you need TR19 inspection at premises on Church End, Perry Lane and Perryfield Court or a nearby road, our technicians can take on the work. Other places close to Bledlow include Pitch Green (1 mile north), Skittle Green (1 mile north-west), Holly Green (1 mile north-west), Horsenden (1 mile north-east) and Henton (1 mile west). Larger places within reach include Aylesbury (8 miles north), High Wycombe (8 miles south-east), Chesham (11 miles east), Marlow (11 miles south-east), Amersham (12 miles east) and Beaconsfield (12 miles south-east).

When to call us in Bledlow

Grease is fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Knowing how much there is lets you act before it becomes a hazard.

Clients normally contact us after spotting something like this:

  • Checking the result of a recent clean
  • Insurance renewals needing proof of TR19 cleaning
  • Systems cleaned on a calendar with no measurements
  • Extracts that may be over the 200 micron mean

If you look after a school kitchen, at a school such as Princes Risborough School or anywhere near Bledlow, the holidays are the usual time for a TR19® clean.

What your quote should include

  • When the next visit should be, and why
  • Proof of accreditation you can verify
  • Exactly which parts of the system are covered
  • If the quote is a fixed price or an estimate
