About our TR19 inspection in Tongham

Not every kitchen fits neatly into a calendar. In a busy kitchen, grease can build faster than the minimum intervals allow for, which is why measurement matters. Our readings give your risk assessment real numbers to work from. If you have surveys needed before quoting a full clean and checking the result of a recent clean, we can help, from post-clean checks, insurer audits and pre-clean surveys onwards.

Around a smaller place like Tongham, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. A kitchen that cooks fewer hours still builds up grease, so cleaning is planned around how much it cooks and what the readings show.

We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Between visits

After the visit, a few habits help the work last:

  • Report grease dripping from the canopy
  • Share inspection reports with your insurer or broker when asked
  • Never cook with filters missing
  • Keep the route to access panels clear

Each report suggests the next clean and the next test, based on the readings and how the kitchen is used.

Test grease regularly instead of relying on the calendar. It shows if build-up is speeding up.

In-house cleaning or a specialist?

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.

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

What affects the cost of TR19 inspection

Before we fix a price, we need to know a few things. We check:

  • The number of sites or systems
  • How big the system is
  • The condition we find in the survey
  • When the work can happen, such as evenings, overnight or weekends

One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before we start.

What we need to know

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

  • A few general shots of the system
  • When the site is open and when it’s quiet
  • Problems your staff have spotted
  • Where the site is and what kind of site it is

Need a price for TR19 inspection? Please call us on 0345 646 2711 or send us an email with a few details about the site. We’ll talk you through the work and send you a fixed quote before anything is booked.

Your questions about TR19 inspection in Tongham

Who would carry out a food hygiene inspection at a kitchen in Tongham?

The local authority for Tongham is Guildford council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.

Can you come to Tongham after we close?

Yes, evening, overnight and weekend work is normal for us. That way a site in Tongham does not have to lose a day’s trading. Let us know the hours you’re closed and we’ll book within them.

Can you verify a clean after it’s been done?

Post-clean verification is a check after a clean, with fresh grease readings and pictures. It works whoever carried out the clean.

Do you offer maintenance contracts?

Yes, of course. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.

Can you come out in an emergency?

Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.

Do you look at the system first?

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

Is a quote from photos possible?

Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote typically follows within one working day. Some sites still need a visit, and we’ll say so.

How do you measure grease in a kitchen extract?

Grease thickness testing measures the layer of grease on the duct surfaces, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). The results are given in microns.

What TR19 inspection cannot fix

Some problems need a different service or another trade:

  • Parts of the duct nobody can reach yet
  • The legal duty, which stays with the responsible person
  • Ductwork that was designed or installed badly

If you’re not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer before booking.

Parts of the system we cover

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

How it 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 it goes on the report too. All told, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. In a smaller place like Tongham, parking is rarely the issue, but tell us about gates, roof access and opening hours.

  1. Post-clean verification is booked once the clean is done.
  2. We open the access points used on the clean.
  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.

Preparing for the visit

  • Have your last certificate or report to hand
  • Tell us the best time to work, such as after service or at a weekend
  • Plan for cooking equipment or plant to be off before we arrive

How to get a quote

For TR19 inspection in Tongham, ring 0345 646 2711 or send us an email. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. We normally send a fixed quote within one working day.

Common problems we fix in Tongham

Not every section of a kitchen extract is easy to get to, and grease can be missed there clean after clean. A survey finds the sections that can’t be reached, so the gaps can be closed.

The symptoms we’re asked about most include:

  • Cleaning intervals that may not suit the kitchen
  • Systems cleaned on a calendar with no measurements
  • Post-clean verification after another contractor’s clean
  • Missing access panels found on survey

Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Wanborough Manor is about 3.1 miles east), access may need planning.

Comparing quotes

  • Whether the figure could change on the day
  • How VAT is shown on the quote
  • How they set the interval to the next visit
  • Proof of accreditation you can verify

How to choose an extract cleaning contractor

Managing agents and facilities teams in Tongham

Tongham kitchens: local notes

Look up Tongham on the FSA’s food hygiene register and you will find about 14 cafés, restaurants and staff canteens and about 18 takeaways in and around Tongham, up to about a mile and a half out. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Environmental health officers from Guildford council inspect food businesses in Tongham. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Tongham is covered by Surrey Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

Bursars and site managers at schools such as St Paul's CofE Infant School & Nursery tend to book extract cleaning for when the kitchen is empty. Healthcare kitchens, like those at hospitals such as Guildford Hospital (about 5.3 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.
