TR19 inspections in West Barnes
TR19 inspection for West Barnes, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Parts of the system left out of past cleans
- Systems that need surveying before cleaning
- An insurer’s request for a TR19 audit
What happens if it’s left?
Without readings, you’re guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. In West Barnes, a planned overnight visit is much easier than closing unexpectedly.

TR19 inspection for kitchens and businesses in West Barnes
Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in West Barnes and across Greater London a clear record of the system’s condition. Typical jobs include kitchen extract systems with no recent grease readings and an insurer’s request for a TR19 audit, across post-clean checks, access surveys and deposit thickness tests.
Kitchens in West Barnes, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
We have been trading since 2009, as 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.

Keeping the system healthy
So the system stays in good health:
- Report grease dripping from the canopy
- Wipe the canopy surfaces regularly
- Mention new equipment or longer hours at the next test
- File every inspection report with your certificates
Keep the verification report next to the certificate it relates to. The pair gives a clear record of the clean and the check.
Keep filters clean and in place. Gaps around filters let grease get past them.
Honest limits
Not every problem is solved by TR19 inspection, and we’d rather say so up front. It doesn’t solve:
- The responsible person’s own fire risk assessment
- Mechanical faults in the extract
- Ductwork that was designed or installed badly
If in doubt, phone us on 0345 646 2711, or send details by email and we will say what we think.

- Access surveys

Your questions about TR19 inspection in West Barnes
Who is the fire and rescue service for West Barnes?
That is London Fire Brigade. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can you come to West Barnes after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in West Barnes keeps running as normal. Tell us your opening hours when you ask for a quote.
What is grease thickness testing?
Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, then compare them with the TR19® Grease figures.
Is TR19 a legal requirement?
No. TR19® is a specification, not a statute. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so following it is the sensible course.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
What do you need from me for a quote?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply give us a ring on 0345 646 2711, or email photos.
Is there a survey before the work?
Yes. We always survey first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
When to call us in West Barnes
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. The old cleaning schedule may not match the kitchen any more.
Most sites get in touch after spotting something like this:
- Systems that need surveying before cleaning
- Ductwork where grease may be over the TR19 limits
- Sections of duct that cannot be reached
- Kitchens whose menu or hours have changed
Bursars and site managers at schools such as Sacred Heart Catholic Primary School tend to book extract cleaning for when the kitchen is empty.

What else we do in West Barnes
West Barnes kitchens: local notes
Food Standards Agency records list about 173 restaurants, cafés and canteens and about 60 sandwich bars and takeaways within about 1.5 miles of central West Barnes. For any of them with a canopy, measuring grease is better than guessing when to clean. Environmental health officers from Merton council inspect food businesses in West Barnes. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
Where a hall near Holy Cross, or anywhere in West Barnes, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you run catering at a healthcare site, such as a hospital like Atkinson Morley Hospital about 1.2 miles north, the extract may need cleaning more often than a part-time kitchen.

What the work involves, part by part
Horizontal duct runs
If a run has no access panel, we note it so panels can be added.
Restaurants, pubs and hotels
Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, and readings show whether that is enough.
How the visit works
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in West Barnes.
- The visit is arranged for when the kitchen is not busy.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- We photograph the test points and record any sections we can’t reach.
- The findings go into a report with readings, pictures and a recommended next clean.
How to prepare
- Clear loose items from the work area
- Let us know about permits to work or site inductions
- Mention any parking or loading restrictions
