TR19 inspection in Lewisham

TR19 inspection in Lewisham

Post-clean verification is a check carried out once the cleaning is done, with new readings and pictures of the cleaned areas. It shows whether the system was left in the condition the paperwork describes. Typical jobs include checking the result of a recent clean and extracts that have never been grease tested, on insurer audits, deposit thickness tests and post-clean checks.

In a London area like Lewisham, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.

Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What happens if it’s left?

After an incident, an insurer can ask to see proof of TR19 cleaning and inspection. Missing records can put a claim at risk. Getting an inspection done now starts that paper trail. A building in Lewisham may have flats or offices above and alongside, and a fault in the system can affect them too.

Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.

Looking after it afterwards

Good habits slow the build-up between visits. Our tips:

  • Report grease dripping from the canopy
  • Keep the route to access panels clear
  • Wipe the canopy surfaces regularly
  • Send TR19 audit reports to your insurer on request

For an insurer audit, send them the report as it is, including readings, photos and any inaccessible sections.

Close the access gaps found during inspection, so every part of the duct can be cleaned.

What happens on the day

Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes an hour or two for a single kitchen, longer for a large or complex system. If your building in Lewisham has sign-in rules, permits or key holders, mention them when you book.

  1. We go through any past certificates and reports.
  2. We follow the extract from canopy to discharge.
  3. We note where access panels are and where more are needed.
  4. We measure the grease and photograph each point.
  5. You get a report and a fixed quote for the clean.

Preparing for the visit

  • Let us know about permits to work or site inductions
  • Find the previous report, if there is one
  • Make sure equipment near the work can be switched off and left to cool

Lewisham kitchens: local notes

The FSA’s food hygiene register includes about 63 bars, pubs and nightclubs and about 11 hotels and guest houses across Lewisham and its immediate surroundings (about a mile and a half). A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Overnight is the normal time to clean a London kitchen extract, so trading is not affected. The fire and rescue service for Lewisham is London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.

If you run catering at a healthcare site, such as a hospital like University Hospital Lewisham about 0.6 miles south-west, the extract may need cleaning more often than a part-time kitchen. Commuter trade near Lewisham station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. A hall kitchen that only cooks for events, whether near St Stephen's Church or elsewhere in Lewisham, still needs its extract cleaned, just less often.

Lewisham is about 3 miles west of Eltham, in Greater London.

Part by part

Vertical risers

In buildings with several floors, the riser may pass through other tenants’ space, so access is planned in advance.

Extract fan and discharge

We look at where the extract discharges outside, as grease can build up there too.

What TR19 inspection cannot fix

TR19 inspection cannot fix everything, and we will tell you before work begins. It will not put right:

  • Sections with no access, until panels are fitted
  • The legal duty, which stays with the responsible person
  • Design faults in the extract system

If you’re not sure, just call 0345 646 2711 or drop us a line and we will give you a straight answer.

Parts of the system we cover

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

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. The inside of ducts and units needs a specialist.

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Lewisham questions

Do you work at weekends in Lewisham?

Yes, we can come after you close and finish before you open. It means the site in Lewisham keeps running as normal. When you call us on 0345 646 2711 or drop us a line, mention when the site is quiet.

Who is the fire and rescue service for Lewisham?

It’s London Fire Brigade, which covers Lewisham. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

What is a WFTT or DTT grease test?

The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. We take readings at set points from canopy to fan.

How often should grease be tested?

That varies with the kitchen’s daily use. BESA sets minimum cleaning intervals of 3, 6 or 12 months by daily use, and testing shows if your kitchen needs more.

Why survey before a clean?

We check the layout, the grease levels and the access, so the clean goes to plan. Missing access panels are noted ahead of the clean.

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 fixed quote is built on it.

Is TR19 cleaning the law?

No. TR19® is a specification, not a statute. Without TR19 records, an insurance claim can be reduced or refused, so it matters in practice.

Is Lewisham in your area?

Yes. We work in Lewisham and across Greater London, as part of our work across South East England and London. For a fixed quote, phone us on 0345 646 2711, or email photos.
