TR19 inspection across Hertford Heath

What happens on the day

A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes around an hour or two per canopy and duct system. The timing of a visit to Hertford Heath is set by you, and the travel is our side of the planning.

  1. We go through any past certificates and reports.
  2. The layout is traced from the canopy to the discharge.
  3. We note where access panels are and where more are needed.
  4. Grease readings are taken and pictures recorded.
  5. You get a report and a fixed quote for the clean.

How to prepare

  • Dig out any earlier paperwork for the system
  • Clear loose items from the work area
  • Make sure someone can let us in and lock up afterwards

Getting a quote

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Advice

TR19 inspection for kitchens and businesses in Hertford Heath

BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Grease testing shows whether your kitchen needs cleaning more often than that. The work covers pre-clean surveys, access surveys and deposit thickness tests, and people most often call us about kitchens taken over with no cleaning records and pre-clean surveys before a first TR19 clean.

In a village or hamlet like Hertford Heath, 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.

A written report with pictures follows each visit, 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.

What we are called out for in Hertford Heath

Records can go missing when a business changes hands or contractors. With no history, the current state of the extract is a guess.

Look out for any of the following:

  • Surveys needed before quoting a full clean
  • Kitchens whose menu or hours have changed
  • Missing TR19 certificates or history
  • Sections of duct that cannot be reached

A hospital like Hertford County Hospital, about 2.1 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Before you book anyone

  • Proof of insurance
  • Which accreditations they hold, and whether you can check them
  • How they set the interval to the next visit
  • Whether VAT is included

How to choose an extract cleaning contractor

A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. In Hertford Heath, food businesses are inspected by environmental health officers from East Hertfordshire council. Extraction counts as kitchen equipment, so its condition can come up on the day.

Leave it or put it right?

Post-clean verification shows whether the system was left the way the certificate says, while there’s still time to put anything right. It’s worth booking a check, because nobody sees inside a duct day to day.

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711, or email photos for straight advice and a fixed quote.

Hertford Heath: your questions answered

Can a school canteen extract in Hertford Heath be done out of term time?

Yes. Half-terms and the summer break are the natural time for school work. With about 14 schools and colleges on the FSA’s register within roughly a mile and a half of Hertford Heath, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711 or use the quote form, and we’ll fit the work in.

Who enforces fire safety at workplaces in Hertford Heath?

It’s Hertfordshire Fire and Rescue Service, which covers Hertford Heath. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

How much does TR19 inspection cost in Hertford Heath?

It depends on the site, so we quote each one individually. To get one, phone us on 0345 646 2711, or send details by email and tell us about the site and its opening hours.

At what point does grease need cleaning?

TR19® Grease says grease should not go over a mean of 200 microns between cleans. 500 microns or more at any point calls for immediate spot cleaning.

Do you work in Hertford Heath?

Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Hertford Heath included.

How do you measure grease in a kitchen extract?

We measure the grease at set points with a WFTT or DTT test, and set against the TR19® Grease figures.

Do you survey before quoting?

Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.

What do you do with what you remove?

We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.

How the job changes from site to site

Horizontal duct runs

Flat duct runs collect grease along their base. Readings are taken along each run through its access panels.

Extract fan and discharge

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

What TR19 inspection cannot fix

In fairness, there are a few things this work won’t fix:

  • The grease itself, which needs a full or spot clean
  • Parts of the duct nobody can reach yet
  • Fire safety duties beyond the extract system

Not sure which it is? You can phone us on 0345 646 2711, or email photos and we will tell you honestly before booking.

What the work covers

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

What your team can do, and what needs us

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 can diagnose it and quote.

Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

Aftercare tips

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

  • Wipe the canopy surfaces regularly
  • Mention new equipment or longer hours at the next test
  • File every inspection report with your certificates
  • Share inspection reports with your insurer or broker when asked

You get a report with the grease readings, where they were taken and photos of each point. File it alongside your TR19 certificates.

Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.
