TR19 inspection across Smallford

What we are called out for in Smallford

Records can go missing when a business changes hands or contractors. With no history, the current state of the extract is a guess.

Clients usually contact us after spotting something like this:

  • Kitchens taken over with no cleaning records
  • Uncertainty over how often to clean
  • Post-clean verification after another contractor’s clean
  • Insurers asking for TR19 evidence

Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Hatfield House is about 2.7 miles east), access may need planning.

Before you book anyone

  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • What insurance they carry
  • Whether a survey comes first
  • Whether they recommend a next date

Choosing a duct cleaning contractor

TR19 inspection in Smallford, done properly

Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). The results show whether the system needs cleaning and how soon. If you have kitchens whose menu or hours have changed and sites with gaps in their extract records, we can put it right.

In a village or hamlet like Smallford, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease.

The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

FAQs for Smallford

Can school kitchens in Smallford be cleaned in the holidays?

Yes. Half-terms and the summer break are the natural time for school work. Around Smallford, the Food Standards Agency lists about 4 schools and colleges with registered kitchens within a mile and a half or so. Just give us a ring on 0345 646 2711, or email photos with your term dates and we will plan around them.

Which council inspects kitchens in Smallford?

Food hygiene inspections in Smallford are carried out by St Albans City council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.

Can you inspect our extract for our insurance company?

Yes, for kitchens across the South East and London. Tell us what your insurer has asked for and we’ll set the report out to match.

Do you cover Smallford?

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

What happens if you cannot reach some of it?

We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.

Do we have to follow TR19 by law?

No, TR19® is not legislation. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, which in a kitchen includes grease in the extract. Many insurers also expect TR19 cleaning.

What should I send you?

Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then phone us on 0345 646 2711 or drop us a line.

Do you have a 24/7 line?

Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.

What we do, step by step

The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes anything from an hour for a small canopy and short duct to a good part of a day for a large site, and the area is cleaned down before we leave. Somewhere as small as Smallford, the date and timings are agreed with you well before the day.

  1. We go through any past certificates and reports.
  2. The layout is traced from the canopy to the discharge.
  3. Access panels are located and any missing ones noted.
  4. We measure the grease and photograph each point.
  5. We report back with readings and a fixed quote.

Before we arrive

  • Mention any sign-in, permit or induction we need
  • Plan for cooking equipment or plant to be off before we arrive
  • Clear the space around the work

Getting a quote

To help us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711 or email us.

Advice

What staff can safely do

Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

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.

What TR19 inspection looks like in Smallford

Food Standards Agency data counts about 41 cafés, restaurants and staff canteens and about 18 takeaways and sandwich shops across Smallford and its immediate surroundings (about a mile and a half). For any of them with a canopy, measuring grease is better than guessing when to clean. Kitchens in Smallford get their food hygiene inspections from St Albans City council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready. Smallford sits within the area of Hertfordshire 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.

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hill End Hospital is the nearest hospital to Smallford, about 1.4 miles south-west. A hall kitchen that only cooks for events, whether near Church of St Mark or elsewhere in Smallford, still needs its extract cleaned, just less often.

What the work involves, part by part

Canopy and plenum

Behind the filters, the plenum catches plenty of grease. We take readings there and photograph it on every inspection.

Horizontal duct runs

Grease settles on the floor of horizontal ducts as the air cools. Readings are taken along each run through its access panels.

What affects the quote in Smallford

Every site gets its own quote. This is what makes a difference:

  • Whether we need access equipment or extra panels
  • When the work can happen, such as evenings, overnight or weekends
  • The condition of the system
  • Site requirements such as sign-in and permits

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’ll explain what it covers.

What to send for a quote

Photos and a few facts are often enough to price the work. Useful things to send:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Your last certificate, test record or report
  • Where the site is and what kind of site it is
  • Photos showing the whole system and its surroundings

Want a quote for TR19 inspection? Please ring 0345 646 2711, or send details by email and tell us about the site. We’ll talk you through the work and give you a fixed quote before anything is booked.

For landlords and multi-site operators

When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

Aftercare tips

So the system stays in good health:

  • Have the latest report ready for insurance renewals
  • Mention new equipment or longer hours at the next test
  • Clean or swap grease filters as often as the kitchen needs
  • Don’t box in or cover duct access panels

For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.

Keep certificates, reports and readings in one place so you can produce them quickly.
