TR19 inspection in Woodlands, done properly

Post-clean verification is a check carried out once the cleaning is done, with fresh grease readings, photos and a look at the areas that were cleaned. It gives you evidence of how the system was actually left. The work covers deposit thickness tests, pre-clean surveys and post-clean checks, and common reasons people get in touch are kitchen extract systems with no recent grease readings and cleaning intervals that may not suit the kitchen.

Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Woodlands, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.

The paperwork matters as much as the work. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Looking after it afterwards

After the visit, a few habits help the work last:

  • Keep canopy edges and gutters wiped down
  • Share inspection reports with your insurer or broker when asked
  • Look out for grease drips round the canopy edge
  • Diary the next grease test and clean

Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can quote to do it.

Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.

Part by part

Vertical risers

In buildings with several floors, the riser may pass through other tenants’ space, so we arrange access ahead of time.

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’s enough.

Fixed quotes for TR19 inspection in Woodlands

We quote each job individually. This is what makes a difference:

  • Where the site is and how we reach it
  • One-off work versus a regular cycle
  • How big the system is
  • The condition we find in the survey

You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.

Asking for a quote

To help us quote quickly, please include:

  • How we’d reach plant on a roof or in a plant room
  • When the site is open and when it’s quiet
  • Detail shots of panels, filters and grilles
  • A few general shots of the system

Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then call us on 0345 646 2711 or send us an email.

What we are called out for in Woodlands

Grease in a duct is flammable fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Measuring it is the first step to keeping it under control.

If you notice any of these, it’s worth a diagnosis:

  • Kitchens taken over with no cleaning records
  • Checking the result of a recent clean
  • Extracts that have never been grease tested
  • Kitchens whose menu or hours have changed

A kitchen near Isleworth station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Questions to ask before booking

  • Whether they’re fully insured
  • Whether inaccessible sections are listed on the report
  • Whether they recommend a next date
  • Whether VAT is included

Our hiring checklist

For landlords and multi-site operators

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.

TR19 inspection around Woodlands

There are about 259 restaurants, cafés and canteens and about 98 takeaways within about 1.5 miles of central Woodlands, according to the Food Standards Agency’s register. For any of them with a canopy, measuring grease is better than guessing when to clean. Environmental health officers from Hounslow council inspect food businesses in Woodlands. 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. Woodlands sits within the area of London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

If you run a church or community hall kitchen, near Church of St Mary the Virgin or elsewhere in Woodlands, its extract still collects grease from every lunch and event. If you run catering at a healthcare site, such as a hospital like West Middlesex University Hospital about 0.7 miles east, the extract may need cleaning more often than a part-time kitchen.

Woodlands: your questions answered

Can school kitchens in Woodlands be cleaned in the holidays?

Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 32 schools, colleges and universities with registered kitchens within about a mile and a half of Woodlands. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Can parking be tricky for a job in Woodlands?

Tell us where a van can stop near your site in Woodlands, and about any building rules on loading. Much of our London work is done overnight, which helps.

What about areas you cannot get to?

We record them on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.

What is post-clean verification?

We visit after a clean, take readings at set points and photograph the system. The report flags anything missed.

Is there a survey before the work?

Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.

Can you look after several sites?

Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.

What’s TR19?

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, and TR19® Air covers general supply and extract systems.

Do we have to follow TR19 by law?

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 insurers also expect TR19 cleaning.

What a clean won’t put right

Some problems need a different service or another trade:

  • Fire safety duties beyond the extract system
  • Ductwork that was designed or installed badly
  • The grease itself, which needs a full or spot clean

If in doubt, phone us on 0345 646 2711 or use the quote form and we’ll say what we think before booking.

What happens on the day

The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes around an hour or two per canopy and duct system, and we clear up before we go. Expect the work in Woodlands to happen after your last customer leaves, not during trading.

  1. First we look at the system’s cleaning history, if there is one.
  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.
