TR19 inspection across St Margarets

Aftercare tips

A little care between visits keeps the system in better shape. Our advice:

  • Keep access panels clear and unpainted
  • Keep to the recommended interval
  • Share inspection reports with your insurer or broker when asked
  • Tell us if menus or opening hours change

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

Test grease regularly instead of relying on the calendar. It spots changes in how fast grease builds.

TR19 inspection in St Margarets, done properly

Before any clean in St Margarets, 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 grease readings are taken at set points. The work covers pre-clean surveys, wet film thickness tests and deposit thickness tests, and the jobs we see most are post-clean verification after another contractor’s clean and surveys needed before quoting a full clean.

Somewhere as small as St Margarets, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.

Duct Doctor has been trading since 2009, and we’re 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.

Why it’s worth doing now in St Margarets

Post-clean verification shows whether the system was left the way the certificate says, while there’s still time to put anything right. A planned visit to St Margarets is easier to arrange than an emergency callout.

Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.

Multi-site and managed buildings

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.

From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.

Common questions in St Margarets

Is St Margarets within the area you cover?

Yes. St Margarets is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.

Which fire service covers St Margarets?

Fire safety enforcement in St Margarets is handled by Kent Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Can you inspect our extract for our insurance company?

Yes. Our TR19 audits cover readings, photos, access and a recommended cleaning interval. You can pass it straight to your insurer or broker.

Where does the waste go?

Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.

How often should a kitchen extract be inspected?

That varies with the kitchen’s daily use. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and grease readings help set the real interval.

What happens on a pre-clean survey?

We look at the system from canopy to discharge, take grease readings and check access. It lets us plan the clean and send you a fixed quote.

What’s TR19?

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.

What does TR19 inspection cost?

Every site is different, so each gets its own fixed quote. To get one, call us on 0345 646 2711, or send details by email with the site type, opening hours and a few photos.

What staff can safely do

Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

What we do, step by step

We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Seeing the system in photos first means the trip to St Margarets can be planned properly.

  1. Post-clean verification is booked once the clean is done.
  2. We open the access points used on the clean.
  3. We repeat the WFTT or DTT readings.
  4. Photos are taken to show the condition after the clean.
  5. The results are reported, with anything missed flagged.

How to prepare

  • Name a contact who can let us in at the agreed time
  • Move anything stored near the system
  • Plan for cooking equipment or plant to be off before we arrive

Grease, kitchens and St Margarets

Food Standards Agency records include about 4 pubs, bars and clubs in and around St Margarets, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Fire safety in St Margarets falls to Kent Fire and Rescue Service. 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. Environmental health officers from Sevenoaks council inspect food businesses in St Margarets. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

If you run catering at a historic house or estate in the area (Lullingstone Castle is about 4.5 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning. A hospital like Darent Valley Hospital, about 1.7 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Volunteers running a hall kitchen near Church of St Margaret of Antioch, or anywhere in St Margarets, may not know when the extract was last cleaned, and a grease test settles it.

St Margarets is about 3 miles south-east of Dartford, in Kent. Whether your site is in the middle of St Margarets or further out, TR19 inspection is available to all kinds of commercial premises, from small sites to large estates.

What a clean will not put right

We won’t sell you work that doesn’t address the problem, so these are the things it won’t cover:

  • A faulty or failing extract fan
  • Hidden runs that need access panels first
  • The grease itself, which needs a full or spot clean

If in doubt, call 0345 646 2711 or email us and we will say what we think.

What we work on in St Margarets

  • Access surveys
  • Post-clean checks
  • Pre-clean surveys

How we price TR19 inspection

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

  • Whether several sites go on one quote
  • Site requirements such as sign-in and permits
  • The times the site is available
  • Access, including roofs, risers and ceiling voids

A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.

What we need to know

To help us quote quickly, please include:

  • When the site is open and when it’s quiet
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • How we’d reach plant on a roof or in a plant room
  • The postcode and the type of business

We don’t publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, call us on 0345 646 2711 or drop us a line.
