About our TR19 inspection in Farnborough

A grease test measures how thick the grease is inside a kitchen extract system. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). From the numbers, you can see whether cleaning is due. We’re often asked to deal with insurance renewals needing proof of TR19 cleaning and uncertainty over how often to clean, across pre-clean surveys, deposit thickness tests and wet film thickness tests.

London kitchens tend to trade late and open early, so extract cleaning in Farnborough is normally done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Your questions about TR19 inspection in Farnborough

Do you clean school canteen extracts around Farnborough out of term?

Yes, holiday work suits schools best. The FSA’s register shows about 7 schools and colleges with food registrations within roughly a mile and a half of Farnborough. Send us your term dates when you ring 0345 646 2711 or email us, and we’ll fit the work in.

Can you work in Farnborough outside opening hours?

Yes, nights and weekends are routine for us. The work in Farnborough can fit around your hours. Your opening times are the first thing we ask for.

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.

Why survey before a clean?

We check the layout, the grease levels and the access, before anyone starts cleaning. Missing access panels are noted so they can be sorted first.

Which accreditations do you hold?

BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we are fully insured.

What does TR19 inspection cost?

We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before any work starts.

Is TR19 a legal requirement?

No, not in itself. But the responsible person must assess and reduce fire risk under the Fire Safety Order 2005, and grease in the extract is part of that. Many insurance policies also require TR19 adherence.

What does TR19 mean?

TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

Aftercare tips

No system stays clean for ever, but care slows the build-up. Our tips:

  • Keep to the recommended interval
  • Clean or swap grease filters as often as the kitchen needs
  • Don’t box in or cover duct access panels
  • Send TR19 audit reports to your insurer on request

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.

What TR19 inspection can’t fix

Some problems need a different service or another trade:

  • Fan breakdowns, which need a repair visit
  • Installation problems, which fall under design guidance such as DW172
  • Fire safety duties beyond the extract system

Not sure which it is? You can ring 0345 646 2711, or send details by email and we’ll tell you honestly.

Where we work

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

What staff can safely do

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.

What happens on the day

There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes a couple of hours for a typical kitchen extract system. Night and weekend working is normal for us in London, and a site in Farnborough is no exception.

  1. The visit is arranged for when the kitchen is not busy.
  2. The system is checked from canopy to discharge.
  3. Grease thickness is measured at set points by WFTT or DTT.
  4. We photograph the test points and record any sections we cannot reach.
  5. You get a report with readings, photos and recommendations.

How to prepare

  • Have your last certificate or report to hand
  • Tell us where we can park and unload
  • Let us know when the site is closed or quiet

How to get a quote

Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before we start.

Advice

Common problems we fix in Farnborough

TR19® is the benchmark that insurers, fire officers and EHOs refer to. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and in a kitchen that means keeping grease under control.

Keep an eye out for any of the following:

  • Extracts that may be over the 200 micron mean
  • Systems that need surveying before cleaning
  • Sections of duct that cannot be reached
  • Missing TR19 certificates or history

For schools such as Farnborough Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

Before you book anyone

  • If they look at the system before pricing
  • How they set the interval to the next visit
  • What’s included in the scope, part by part
  • Whether the figure could change on the day

How to choose an extract cleaning contractor

Kitchen extracts in Farnborough

The Food Standards Agency lists about 14 pubs and bars as registered food businesses within roughly a mile and a half of the centre of Farnborough. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in Farnborough get their food hygiene inspections from Bromley council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.

Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Down House is about 2.1 miles south-west), access may need planning. Healthcare kitchens, like those at hospitals such as Orpington Hospital (about 0.9 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Farnborough is about 2 miles south-west of Orpington, in Greater London. Across the BR6 area, we can carry out TR19 inspection at your premises. Our area takes in 764 places across Greater London, large and small. We also work in London, around 12 miles away.

We cover every part of BR6 for TR19 inspection and the streets around it. TR19 inspection is available to premises on Tye Lane, Peel Road and Pitt Road and the roads around them. If your site is just outside Farnborough, we cover Green Street Green (1 mile south-east), Locksbottom (1 mile north-west), Crofton (1 mile north), Farthing Street (1 mile south-west) and Downe (2 miles south-west). Further out, we also cover London (12 miles north-west), City of Westminster (15 miles north-west), Marylebone (15 miles north-west), Kensington (15 miles north-west), St Pancras (14 miles north-west) and Shoreditch (13 miles north-west).

What affects the quote in Farnborough

Some jobs are bigger than they look, and some smaller. The main factors:

  • The number of sites or systems
  • How easy every part is to reach
  • Site rules, permits and inductions
  • Whether it’s a one-off visit or part of a schedule

Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.

What we need to know

The more you tell us, the more accurate the quote. When you get in touch, it helps to send:

  • The site address and the type of premises
  • The times we could work without disrupting the site
  • A few general shots of the system
  • Any symptoms, from odd noises to smells or leaks

The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

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. Where responsibility is shared, records matter even more.

Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
