TR19 inspection near South Street

Do you need TR19 inspection in South Street?

You cannot judge grease thickness by eye. Clean filters can hide a heavy layer behind them, which is why readings matter.

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

  • Pre-clean surveys before a first TR19 clean
  • An insurer’s request for a TR19 audit
  • Parts of the system left out of past cleans
  • Kitchens whose menu or hours have changed

If you run catering at a historic house or estate in the area (Cobham College is about 3.3 miles north-east), event kitchens in older buildings often have awkward duct runs that need planning.

Our hiring checklist

How we handle TR19 inspection in South Street

Before any clean in South Street, we survey the canopy, plenum, filters, ducts, fan and discharge. We check where the access panels are and whether every section can be reached, and record grease readings at set points. If you’re dealing with kitchens taken over with no cleaning records and confirming a clean reached the whole system, we can put it right.

Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.

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

In-house cleaning or a specialist?

Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.

Grease, kitchens and South Street

The FSA’s data shows about 7 pubs, bars and clubs registered in South Street and the streets around it, up to about 1.5 miles out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Fire safety in South Street falls to Kent Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In South Street, food businesses are inspected by environmental health officers from Gravesham council. 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.

Term dates shape school work: for a school like Culverstone Green Primary School, an extract clean fits neatly into a half-term or summer break.

South Street: your questions answered

Which fire authority looks after South Street?

Fire safety enforcement in South Street is handled by Kent Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

Is South Street within the area you cover?

Yes. South Street is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.

Do you carry out TR19 audits for insurers?

Yes, anywhere in the area we cover. Share the insurer’s request so the report addresses it.

Which kinds of sites do you work on?

Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

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.

How do you measure grease in a kitchen extract?

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.

How long does a TR19 inspection take?

Expect it to take anything from an hour for a small canopy and short duct to a good part of a day for a large site. We fit it around when the kitchen is closed or quiet.

Do you look at the system first?

Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.

Fixed quotes for TR19 inspection in South Street

Before we fix a price, we need to know a few things. We look at:

  • Site requirements such as sign-in and permits
  • Parking and loading at the site
  • The condition of the system
  • Access, including roofs, risers and ceiling voids

Kitchens, offices, schools and hospitals are all priced 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’ll go through it with you.

Helping us quote

There’s no need for technical detail. Just send:

  • Problems your staff have spotted
  • Close-ups of filters, grilles, hatches or access panels
  • The roof, plant room or outside wall the system runs to
  • The times we could work without disrupting the site

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

What happens on the day

There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes around an hour or two per canopy and duct system. Pictures of the system and its access let us plan the work in South Street before we set off.

  1. We go through any past certificates and reports.
  2. We follow the extract from canopy to discharge.
  3. Access panels are located and any missing ones noted.
  4. Grease readings are taken and pictures recorded.
  5. You get a report and a fixed quote for the clean.

Before we arrive

  • Mention any parking or loading restrictions
  • Tell us about site rules, permits or sign-in
  • Plan for cooking equipment or plant to be off before we arrive

Ask for a quote

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Advice

What the work involves, part by part

Extract fan and discharge

A greasy fan works harder and wears faster. Readings show if it needs attention before the next clean.

Schools, hospitals and care homes

We fit testing around service times and school holidays to avoid disruption.

Aftercare tips

So the system stays in good health:

  • Flag oily drips near the extract
  • Clean or swap grease filters as often as the kitchen needs
  • Share inspection reports with your insurer or broker when asked
  • Wipe the canopy surfaces regularly

The audit report is set out to pass straight to your insurer or broker, including readings, pictures and any inaccessible sections.

Keep filters clean and in place. Missing or damaged filters let grease straight into the plenum.

Why deal with it now?

Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Ignored, the layer only gets thicker. Our emergency line runs 24/7, but a planned visit to South Street is calmer for everyone.

The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.

Why South Street businesses choose us

  • A single point of contact for sites across the South East and London
  • Fully insured
