TR19 inspection for kitchens and businesses in Basingstoke

A pre-clean survey looks at the whole system, from canopy to discharge. Access is checked along the full length, and grease readings are taken at set points. We’re often asked to deal with an insurer’s request for a TR19 audit and kitchens taken over with no cleaning records, on deposit thickness tests, access surveys and pre-clean surveys.

In a place the size of Basingstoke, the kitchens with extract systems range from takeaways and restaurants to hotel, school and workplace kitchens. BESA’s minimum intervals run from every three months for heavy use to once a year for light use, so the right schedule depends on the kitchen.

Every visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Your questions about TR19 inspection in Basingstoke

Who enforces fire safety at workplaces in Basingstoke?

Basingstoke is in the area of Hampshire and Isle of Wight Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

Can you clean school kitchen extracts in Basingstoke during the holidays?

Yes, out-of-term visits are normal for schools. The FSA’s register shows about 32 schools and colleges with food registrations within roughly a mile and a half of Basingstoke. Send us your term dates when you call 0345 646 2711 or use the quote form, and we’ll fit the work in.

Do you offer maintenance contracts?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.

What is grease thickness testing?

It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. The results are given in microns.

Can you come out in an emergency?

Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.

At what point does grease need cleaning?

The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. We show your readings against those figures.

How do you protect the area?

We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. At the end, the area is cleaned down.

Can you look after several sites?

Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.

Basingstoke kitchens: local notes

The Food Standards Agency lists about 32 pubs and bars and about 5 hotels, B&Bs and guest houses as registered food businesses within roughly a mile and a half of the centre of Basingstoke. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. It’s Basingstoke and Deane council that sends environmental health officers to food businesses in Basingstoke. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. Hampshire and Isle of Wight Fire and Rescue Service covers Basingstoke. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

For schools such as King's Furlong Infant School and Nursery, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. A kitchen near Basingstoke station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

When something else is needed

Not every problem is solved by TR19 inspection, and we’d rather say so up front. It doesn’t solve:

  • The legal duty, which stays with the responsible person
  • The grease itself, which needs a full or spot clean
  • Design faults in the extract system

If in doubt, ring 0345 646 2711 or email us and we’ll say what we think before booking.

What the work covers

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

In-house cleaning or a specialist?

When your team notices a problem 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 send you a fixed quote.

Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

Signs you need TR19 inspection in Basingstoke

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, so readings are the reliable guide.

What we’re most often called out for:

  • Kitchen extract systems with no recent grease readings
  • Heavy grease suspected in the plenum or ducts
  • Uncertainty over how often to clean
  • Missing access panels found on survey

A hall kitchen that only cooks for events, whether near St Michael's Church or elsewhere in Basingstoke, still needs its extract cleaned, just less often.

Before booking anyone

  • When the next visit should be, and why
  • Whether the work can be done while the site is closed
  • What insurance they carry
  • Whether the quote shows VAT

Choosing a duct cleaning contractor

What we do, step by step

Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, 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. Phased working suits larger sites in a place the size of Basingstoke, with each part handed back before the next starts.

  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. We photograph each area to record how it was left.
  5. The results are reported, with anything missed flagged.

Before we arrive

  • Tell us where we can park and unload
  • Tell us the best time to work, such as after service or at a weekend
  • Find the previous report, if there is one

How to get a quote

To get a fixed quote, ring 0345 646 2711, or email photos 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. You will typically have a quote within one working day.

Aftercare tips

Simple habits between visits make a real difference. Our advice:

  • Keep to the recommended interval
  • Tell us if menus or opening hours change
  • Share inspection reports with your insurer or broker when asked
  • Clean grease off the canopy between professional cleans

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.

Test grease regularly instead of relying on the calendar. It spots changes in how fast grease builds.

Different parts, different methods

Extract fan and discharge

We look at where the extract discharges outside, since grease reaches the very end of the system.

Canopy and plenum

Filters can look fine while the plenum behind them is heavily coated. So we measure behind the filters, not just in front.
