The process

Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes a shift or more, depending on the length of the runs and the number of access points. Loading bays, visitor permits and roof access are the first things we ask about for a site in St Helier.

  1. First the duct route is traced and every access point noted.
  2. Set points along the runs are tested for grease.
  3. Access panels are opened and heavy deposits scraped out by hand.
  4. Horizontal runs and risers are then degreased by the method that suits the deposit.
  5. We test again, take pictures and note any part that couldn’t be reached.

Before we arrive

  • Move anything stored near the system
  • Arrange a key holder or contact on site
  • Let us know about parking and loading

How to get a quote

Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Ductwork cleaning in St Helier, done properly

Not sure when the ductwork was last cleaned? A few details about the system are a good start when you phone us on 0345 646 2711 or email us, and we’ll send you a fixed quote for ductwork cleaning, usually within one working day. The work covers multi-storey ducts, vertical risers and horizontal duct runs, and people most often call us about smells of old cooking grease from the ductwork and duct runs with no cleaning record.

Kitchens in St Helier, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.

Good records are part of the job. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Between visits

Once we’ve finished, these simple steps help:

  • Store the certificate with the fire risk assessment
  • Book the next clean before the recommended date
  • Tell us if grease leaks from the ductwork
  • Do not switch the extract off early

You will have a recommended date for the next clean, based on the readings and your daily cooking hours, in line with BESA guidance.

Extra access panels mean more of the duct gets cleaned each time. Grease you can reach is grease that gets removed.

What ductwork cleaning can’t fix

It’s worth knowing the limits before booking:

  • Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
  • A duct that is too small or badly routed for the kitchen (a design issue)
  • An extract fan that has stopped working

If in doubt, phone us on 0345 646 2711 or send us an email and we’ll say what we think.

What the work covers

  • Vertical risers
  • Access panels
  • Bends and junctions
  • Attenuators
  • Multi-storey ducts
  • Horizontal duct runs

Why act early in St Helier

Insurers know the risk of a greasy duct. Many policies require TR19 cleaning, and a claim may be refused or reduced without evidence. A certificate that covers the ductwork is what they want to see. In St Helier, a planned overnight visit is much easier than closing unexpectedly.

What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before we start.

What affects the cost of ductwork cleaning

You’ll get a fixed price before we start. It’s based on:

  • Site rules, permits and inductions
  • One-off work versus a regular cycle
  • When the work can happen, such as evenings, overnight or weekends
  • The condition we find in the survey

Whatever the type of site, the quote works 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

To help us quote quickly, send us:

  • Any previous report or certificate
  • Detail shots of panels, filters and grilles
  • How we’d reach plant on a roof or in a plant room
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

There’s no standard price list, because every site is different. 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 send details by email.

Your questions about ductwork cleaning in St Helier

Do you work overnight in St Helier?

Yes, we can come after you close and finish before you open. The work in St Helier can fit around your hours. Just call us on 0345 646 2711 or use the quote form with your opening times and we will plan around them.

Which fire service covers St Helier?

It’s London Fire Brigade, which covers St Helier. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

How much notice do you need?

The more notice, the better, particularly for night and weekend visits. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.

What happens if there are not enough access panels?

Ductwork needs access to be cleaned. Those parts are listed, and we can install panels so they’re reached next time.

Is there a survey before the work?

Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.

Can you quote from photos?

Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.

How often does extract ductwork need cleaning?

The minimum depends on how long the kitchen cooks each day: 3-monthly for heavy use, 6-monthly for moderate and 12-monthly for light use. Measured grease sets the real interval.

What paperwork do you give after a duct clean?

Every clean comes with a photo report, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. Keep both in the maintenance log.

Ductwork cleaning around St Helier

The FSA’s data shows about 18 pubs, bars and clubs registered in St Helier and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Kitchens in St Helier get their food hygiene inspections from Sutton council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in St Helier falls to London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

Healthcare kitchens, like those at hospitals such as St Helier Hospital (about within half a mile south), often cook for long hours, which puts them in BESA’s heavier-use bands. Volunteers running a hall kitchen near St Peter's Church, or anywhere in St Helier, may not know when the extract was last cleaned, and a grease test settles it. For kitchens close to Sutton Common station, where the day often starts early and ends late, the extract can be cleaned overnight.

Multi-site and managed buildings

Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

In-house cleaning or a specialist?

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
