What affects the cost of TR19 inspection

Sites vary more than people expect. What affects the quote:

  • Parking and loading at the site
  • Whether it’s a one-off visit or part of a schedule
  • Site rules, permits and inductions
  • The times the site is available

The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

Asking for a quote

What to send for a quote:

  • Any access panels or hatches you can see
  • Any previous report or certificate
  • Photos showing the whole system and its surroundings
  • Problems your staff have spotted

Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711, or send details by email.

How we handle TR19 inspection in Kings Langley

TR19® Grease says grease should not exceed a mean of 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Grease testing shows which side of those lines you are on. Common call-outs are for cleaning intervals that may not suit the kitchen and insurance renewals needing proof of TR19 cleaning, across post-clean checks, access surveys and insurer audits.

In a smaller place like Kings Langley, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. A kitchen that cooks fewer hours still builds up grease, so cleaning is planned around how much it cooks and what the readings show.

Every visit ends with a written report and photos, 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.

Managing agents and facilities teams in Kings Langley

Facilities teams in offices, schools and healthcare sites book us too across Hertfordshire. Larger estates can be phased building by building to keep disruption down.

From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

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 can diagnose it and quote.

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.

Common problems we fix in Kings Langley

Grease builds up as cooking vapour cools inside the extract. It often collects where nobody can see it: the plenum, bends and horizontal runs.

What we are most often called out for:

  • Checking the result of a recent clean
  • Kitchen extract systems with no recent grease readings
  • Kitchens taken over with no cleaning records
  • Missing access panels found on survey

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Leavesden Hospital is the nearest hospital to Kings Langley, about 1.9 miles south-east.

Questions to ask before you book

  • If they look at the system before pricing
  • If the quote is a fixed price or an estimate
  • What paperwork you get at the end

Common questions in Kings Langley

Which fire authority looks after Kings Langley?

That is Hertfordshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

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

That is Dacorum council, whose environmental health officers carry out food hygiene inspections in Kings Langley. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.

How much does TR19 inspection cost in Kings Langley?

We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.

Do you carry out TR19 audits for insurers?

Yes, for kitchens across the South East and London. Tell us what your insurer has asked for and we’ll set the report out to match.

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.

Can the work be done while we are closed?

Yes. Give us your opening hours with your enquiry and we will book around them.

Which accreditations do you hold?

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.

Is TR19 a legal requirement?

No. It’s the benchmark rather than the law. Without TR19 records, an insurance claim can be reduced or refused, so following it is the sensible course.

Advice

Each kitchen extract among them can be measured for grease to set the right cleaning interval. Kitchens in Kings Langley get their food hygiene inspections from Dacorum council. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.

Between visits

A little care between visits keeps the system in better shape. Our advice:

  • Keep canopy edges and gutters wiped down
  • File every inspection report with your certificates
  • Keep the route to access panels clear
  • Keep grease filters clean and fitted properly

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

Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.

What the work involves, part by part

Restaurants, pubs and hotels

Kitchens that cook for long hours build up grease faster. Regular testing shows whether the cleaning interval keeps up.

Schools, hospitals and care homes

School and college kitchens still need their extract checked. Testing shows whether the interval suits.
