TR19 inspection for sites in Streatham

Streatham questions

What do you need to know about parking in Streatham?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we’ll book into it.

Which fire authority looks after Streatham?

It’s London Fire Brigade, which covers Streatham. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

Do you work in Streatham?

Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Streatham.

What grease levels does TR19 allow?

TR19® Grease says grease should not go over a mean of 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.

What information do you need?

The site address, the type of premises and your opening hours, along with a few photos and any previous report.

What is grease thickness testing?

The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. Readings are taken at set points through the system.

What accreditations do you have?

Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.

Do we have to follow TR19 by law?

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.

About our TR19 inspection in Streatham

After a clean, post-clean verification checks the result, with new readings and pictures of the cleaned areas. It shows whether the system was left in the condition the paperwork describes. The work covers post-clean checks, wet film thickness tests and insurer audits, and common reasons people get in touch are ductwork where grease may be over the TR19 limits and checking the result of a recent clean.

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

Good records are part of the job. You get a written report with pictures 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.

What affects the cost of TR19 inspection

Sites vary more than people expect. What affects the quote:

  • The size of the system
  • When the work can happen, such as evenings, overnight or weekends
  • Whether several sites go on one quote
  • Access, including roofs, risers and ceiling voids

Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

What we need to know

What to send for a quote:

  • Wide pictures of the system and the area around it
  • How we’d reach plant on a roof or in a plant room
  • Where the site is and what kind of site it is
  • The paperwork from the last visit, if you have it

There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, call 0345 646 2711 or email us.

For landlords and multi-site operators

From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.

What happens on the day

When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes an hour or two for a single kitchen, longer for a large or complex system. A name and number for whoever controls access to the building in Streatham saves time on the night.

  1. Post-clean verification is booked once the clean is done.
  2. The same access points are opened up.
  3. Grease readings are taken again at set points.
  4. We photograph each area to record how it was left.
  5. The results are reported, with anything missed flagged.

Preparing for the visit

  • Mention any locked doors, roof access or ceiling voids
  • Mention any parking or loading restrictions
  • Allow time for equipment near the work to be turned off and cool down

How to get a quote

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.

TR19 inspection in Streatham: the local picture

Food Standards Agency data counts about 277 cafés, restaurants and staff canteens and about 160 takeaways within 1.5 miles or so of the middle of Streatham. For any of them with a canopy, measuring grease is better than guessing when to clean. In Streatham, food businesses are inspected by environmental health officers from Lambeth council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Most London extract cleaning happens at night, after the last service.

Healthcare kitchens, like those at hospitals such as Tooting Bec Hospital (about 1 mile west), often cook for long hours, which puts them in BESA’s heavier-use bands. Term dates shape school work: for a school like St Andrew's Catholic Primary School, an extract clean fits neatly into a half-term or summer break. Volunteers running a hall kitchen near St Leonard's Church, or anywhere in Streatham, may not know when the extract was last cleaned, and a grease test settles it.

Streatham is about 5 miles south of London, in Greater London. Whatever kind of site you run in Streatham, we can take on TR19 inspection. We can work out of hours so the site keeps running. Our Greater London coverage runs to 764 places, and Streatham is one of them.

Work in SW16, SW2, CR4 and SW12 is surveyed, quoted and booked the same way as anywhere else. That includes premises on Stanthorpe Road, Gleneagle Mews and Madeira Road and the roads around them.

Honest limits

It’s worth knowing the limits before booking:

  • Mechanical faults in the extract
  • Fire safety duties beyond the extract system
  • Ductwork that was designed or installed badly

If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think before booking.

What the work covers

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

In-house cleaning or a specialist?

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Different parts, different methods

Canopy and plenum

Behind the filters, the plenum catches plenty of grease. Readings and pictures are taken in the plenum as part of every survey.

Extract fan and discharge

Grease on the fan adds to wear. Readings show if it needs attention before the next clean.

Looking after it afterwards

Think of this as the after-treatment advice, short and simple:

  • Tell us if menus or opening hours change
  • Report grease dripping from the canopy
  • Do not box in or cover duct access panels
  • Store grease readings where your insurer can see them

You get a report with the grease readings, where they were taken and photos of each point. File it alongside your TR19 certificates.

Keep certificates, reports and readings in one place so the history is easy to show.
