Aftercare tips

How long the results last depends on use and care. We suggest:

  • Keep grease filters clean and fitted properly
  • Wipe the canopy surfaces regularly
  • Flag oily drips near the extract
  • Keep to the recommended interval

You get a report with the grease readings, where they were taken and pictures of each point. Keep it with your fire safety and TR19 records.

Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.

TR19 inspection in Amwell, done properly

Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Grease testing shows which side of those lines you’re on. If you have surveys needed before quoting a full clean and extracts that have never been grease tested, we can help.

Somewhere as small as Amwell, 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.

It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What we do, step by step

The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, which takes an hour or two for a single kitchen, longer for a large or complex system. Photos of the system and how to reach it help us plan a visit to Amwell.

  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. We measure the grease and photograph each point.
  5. We report back with readings and a fixed quote.

How to prepare

  • Name a contact who can let us in at the agreed time
  • Let us know about permits to work or site inductions
  • Let us know when the site is closed or quiet

Getting a quote

Quotes are quick. Call or email with a few details and you will usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

When something else is needed

An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection will not do:

  • Fire safety duties beyond the extract system
  • Removing the grease, which is a separate clean
  • A faulty or failing extract fan

If you’re not sure, just ring 0345 646 2711 or drop us a line and we’ll give you a straight answer.

What the work covers

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

TR19 inspection in Amwell: the local picture

There are about 11 restaurants, cafés and canteens across Amwell and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. Kitchens in Amwell get their food hygiene inspections from St Albans City council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Fire safety in Amwell falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

If you look after a school kitchen, at a school such as St Helen's Church of England Primary School or anywhere near Amwell, the holidays are the usual time for a TR19® clean. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Childwickbury Manor is about 2.6 miles south-west), access may need planning.

What we are called out for in Amwell

Kitchens change: a new menu, longer hours or more frying can all add grease. The old cleaning schedule may not match the kitchen any more.

Keep an eye out for these warning signs:

  • Sites with gaps in their extract records
  • Confirming a clean reached the whole system
  • Surveys needed before quoting a full clean
  • Extracts that may be over the 200 micron mean

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St Albans City Hospital is the nearest hospital to Amwell, about 3.4 miles south-west.

Before booking anyone

  • How they set the interval to the next visit
  • If the quote is a fixed price or an estimate
  • Whether the quote is based on a survey or photos
  • Whether the whole system is included, or only the parts that are easy to reach

How to choose an extract cleaning contractor

What happens if it’s left?

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 Amwell is calmer for everyone.

Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, call us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.

Why us?

  • Fixed quotes, typically within one working day
  • Accredited under CHAS and SafeContractor, with ISO 9001
  • In business since 2009
  • We are fully insured

Common questions in Amwell

Can a school canteen extract in Amwell be done out of term time?

Yes, out-of-term visits are normal for schools. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Amwell. Send us your term dates when you phone us on 0345 646 2711 or use the quote form, and we’ll fit the work in.

Who carries out food hygiene inspections in Amwell?

That is St Albans City council, whose environmental health officers carry out food hygiene inspections in Amwell. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.

How often should grease be tested?

Enough to be sure grease stays within the TR19® Grease figures between cleans. The readings themselves tell you if the interval needs to change.

Can one contract cover all our sites?

Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.

How do you keep the site clean during the work?

We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.

Do you cover Amwell?

Yes. Our technicians work in Amwell, as part of our area across London and the South East.

What happens to the waste?

We take it away at the end of the visit. While we work, it’s kept contained so the area stays clean.

Do you offer emergency callouts?

Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.

For landlords and multi-site operators

Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

What the work involves, part by part

Vertical risers

Vertical risers take the extract up through the floors. Grease can run down and collect at the base, so we check there.

Extract fan and discharge

The discharge at the end of the system is checked as well, as grease can build up there too.
