TR19 inspection for sites in Thursley

Between visits

No system stays clean for ever, but care slows the build-up. A few tips:

  • Store grease readings where your insurer can see them
  • Clean grease off the canopy between professional cleans
  • Keep grease filters clean and fitted properly
  • Have the latest report ready for insurance renewals

After post-clean verification, file the results with the cleaning certificate. The pair gives a clear record of the clean and the check.

Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.

TR19 inspection for kitchens and businesses in Thursley

Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Thursley and across Surrey a clear record of the system’s condition. Typical jobs include confirming a clean reached the whole system and parts of the system left out of past cleans, on wet film thickness tests, post-clean checks and insurer audits.

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.

Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Questions from Thursley

Which fire service covers Thursley?

Fire safety enforcement in Thursley is handled by Surrey Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Can you get to a site in Thursley?

Yes. Villages and rural sites across the South East are part of our work, Thursley included. Let us know about access, parking and anything unusual about getting there when you book.

Do you work out of hours?

Yes, and that is how we prefer to work. The visit is timed for when the area is not in use, such as late evening, overnight or a weekend.

How do you measure grease in a kitchen extract?

The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. We take readings at set points from canopy to fan.

What about areas you can’t get to?

They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.

Do you check other contractors’ cleans?

We visit after a clean, take readings at set points and photograph the system. The report flags anything missed.

What does TR19 mean?

TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

Which sectors do you work in?

Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

Signs you need TR19 inspection in Thursley

Looking at a canopy tells you little about what’s in the duct. A system can look clean at the filters and be heavily coated further in, which is why readings matter.

The symptoms we are asked about most include:

  • Extracts that may be over the 200 micron mean
  • Pre-clean surveys before a first TR19 clean
  • An insurer’s request for a TR19 audit
  • Kitchens taken over with no cleaning records

A hall kitchen that only cooks for events, whether near Church of St Michael and All Angels or elsewhere in Thursley, still needs its extract cleaned, just less often.

Before booking anyone

  • Proof of accreditation you can verify
  • What hours they’ll be on site
  • Whether inaccessible sections are listed on the report
  • How VAT is shown on the quote

How to choose an extract cleaning contractor

Multi-site and managed buildings

Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.

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.

Honest limits

We won’t sell you work that doesn’t address the problem, so these are the things it will not cover:

  • Removing the grease, which is a separate clean
  • Design faults in the extract system
  • Fire safety duties beyond the extract system

Not sure which it is? You can call 0345 646 2711, or email photos and we will tell you honestly.

Parts of the system we cover

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

What we do, step by step

We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes around an hour or two per canopy and duct system. A quick note on how to find the site and where to park makes a visit to Thursley run smoothly.

  1. After the clean, we arrange a time to check the system.
  2. The same access points are opened up.
  3. Grease readings are taken again at set points.
  4. Photos are taken to show the condition after the clean.
  5. We report the findings and flag any areas that need more work.

Before we arrive

  • Agree a time when the area can be out of use
  • Find the previous report, if there is one
  • Mention any sign-in, permit or induction we need

Getting 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, you get a fixed price before any work starts.

Thursley kitchens: local notes

About 36 miles out from central London, Thursley is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you. Kitchens in Thursley get their food hygiene inspections from Waverley council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand.

If you run catering at a healthcare site, such as a hospital like Milford Hospital about 4 miles east, the extract may need cleaning more often than a part-time kitchen.

Thursley is about 5 miles south-east of Farnham, in Surrey. We carry out TR19 inspection for businesses, landlords and public buildings in Thursley and the rest of Surrey. Our area takes in 395 places across Surrey, from busy centres to quieter spots. We also work in Guildford, about 9 miles from Thursley.

Every address in GU8 is within our area for TR19 inspection, from the main roads to the quietest streets. That includes premises on The Street, The Lane and Dyehouse Road and the roads around them. Close by, we work in Pitch Place (1 mile west), Rushmoor (2 miles west), Tilford Common (2 miles north-west), Green Cross (2 miles south-west) and Elstead (2 miles north). Larger places within reach include Guildford (9 miles north-east), Woking (13 miles north-east), Camberley (13 miles north), Farnham (5 miles north-west), Frimley (11 miles north) and Haslemere (4 miles south).

Landmarks near Thursley

Locally, jobs take us to businesses close to Three Horseshoes pub. Thursley’s nearest station is Witley station, roughly 3.1 miles east. Other landmarks nearby include Milford Hospital (4 miles east). Not far away are Upper Lake and Gibbet Hill.

Part by part

Schools, hospitals and care homes

Hospital and care home kitchens can cook all day, every day. Readings show if cleaning is frequent enough.

Horizontal duct runs

If a run has no access panel, we note it so panels can be added.

What your team can do, and what needs us

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’ll take a look and give you a fixed quote.

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
