What affects the cost of TR19 inspection

Your quote is based on your site. We take into account:

  • How many systems or sites are involved
  • Where the site is and how we reach it
  • Working hours and out-of-hours timing
  • Any permits to work or inductions

No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

What we need to know

Many jobs can be priced from pictures and some basics. Send what you can of the following:

  • Wide pictures of the system and the area around it
  • Your opening hours and when the area is out of use
  • How we’d reach plant on a roof or in a plant room
  • The paperwork from the last visit, if you have it

Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.

About our TR19 inspection in New Barn

Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Grease testing shows which side of those lines you’re on. If you’re dealing with missing TR19 certificates or history and missing access panels found on survey, we can put it right.

Kitchens around a place like New Barn are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.

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

Staff cleaning versus specialist work

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

New Barn: your questions answered

Can you work in New Barn outside opening hours?

Yes, we can come after you close and finish before you open. It means the site in New Barn keeps running as normal. Let us know the hours you are closed and we will book within them.

Will you come out to New Barn?

Yes, New Barn is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.

What is a WFTT or DTT grease test?

Grease thickness testing measures the layer of grease on the duct surfaces, by WFTT or DTT. Each reading is recorded in microns.

Do you work with multi-site operators?

Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.

How much does TR19 inspection cost?

Every site is different, so each gets its own fixed quote. For a quote, call us on 0345 646 2711 or send us an email and tell us about the site and its opening hours.

What’s TR19?

A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.

What do the grease readings need to be?

Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.

Which accreditations do you hold?

We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Landlords, agents and facilities managers

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.

How the visit works

When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Your opening hours decide when we come to New Barn, not ours.

  1. After the clean, we arrange a time to check the system.
  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.

How to prepare

  • Let us know when the site is closed or quiet
  • Mention any parking or loading restrictions
  • Name a contact who can let us in at the agreed time

How to get a quote

Common problems we fix in New Barn

Grease builds up as cooking vapour cools inside the extract. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.

Common reasons sites call us are:

  • Post-clean verification after another contractor’s clean
  • Heavy grease suspected in the plenum or ducts
  • Missing access panels found on survey
  • Kitchens taken over with no cleaning records

A hospital like Gravesham Community Hospital, about 3.6 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Questions to ask before you book

  • How they set the interval to the next visit
  • Whether the price is fixed
  • Whether the quote is based on a survey or pictures
  • When they can work, and whether that’s outside your opening hours

Kitchen extracts in New Barn

The FSA’s food hygiene register shows about 8 cafés, restaurants and staff canteens and about 7 takeaways and sandwich shops in and around New Barn, up to about a mile and a half out. For any of them with a canopy, measuring grease is better than guessing when to clean. New Barn is covered by Kent 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. In New Barn, food businesses are inspected by environmental health officers from Dartford council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand.

Historic houses near New Barn, such as Cobham College about 3.1 miles east, are a reminder that older buildings with event kitchens can have long, awkward duct routes. If you run a church or community hall kitchen, near Church of Saint Mary Magdalene or elsewhere in New Barn, its extract still collects grease from every lunch and event.

Aftercare tips

Aftercare is simple, and it helps at the next visit:

  • Report grease dripping from the canopy
  • Tell us if menus or opening hours change
  • Store grease readings where your insurer can see them
  • Keep access panels clear and unpainted

The report recommends when the system should next be cleaned and tested, from the measured grease and the kitchen’s hours.

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