Landlords, agents and facilities managers

We work for landlords, managing agents and facilities managers as well as the people running the site. 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.

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.

Ductwork cleaning for kitchens and businesses in Stevenage

Duct cleaning is the hardest part of an extract clean, and the part most often skipped. Without enough access panels, long stretches can go years without being touched. We open up every reachable section and record any we can’t reach, so you know exactly where you stand. Typical jobs include duct runs with no cleaning record and sections of duct with no access panels, across multi-storey ducts, vertical risers and attenuators.

In Stevenage, extract cleaning fits around service: late at night, early in the morning or on a closed day. Bigger sites can be done kitchen by kitchen, so cooking carries on elsewhere.

Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Common questions in Stevenage

Do you clean school canteen extracts around Stevenage out of term?

Yes, and it’s the easiest time to do it. With about 39 schools and colleges on the FSA’s register within roughly a mile and a half of Stevenage, it pays to plan holiday dates ahead. Just call us on 0345 646 2711 or email us with your term dates and we’ll plan around them.

Do you work overnight in Stevenage?

Yes. We work evenings, overnight and at weekends. That way a site in Stevenage doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.

Can you look after several sites?

Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.

How long will the duct clean take?

It depends on the length of the duct, the number of access panels and how much grease there is. As a guide, it takes from a few hours to more than one visit, depending on duct length and access.

What should I send you?

The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.

Can you quote from pictures?

Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. If pictures aren’t enough, we will survey first.

Do you install duct access panels?

Yes, we fit access panels where the duct needs them. That lets the next clean reach sections that were missed, and the report will show where they’re needed.

What’s TR19?

TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

Fixed quotes for ductwork cleaning in Stevenage

We do not publish a price list, because no two systems are the same. What we look at:

  • Whether it’s a one-off visit or part of a schedule
  • How easy every part is to reach
  • Site requirements such as sign-in and permits
  • The number of sites or systems

A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.

What we need to know

There’s no need for technical detail. It helps if you can send:

  • The site address and the type of premises
  • Any previous report or certificate
  • The times we could work without disrupting the site
  • Photos showing the whole system and its surroundings

Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.

What we do, step by step

When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes anything from a few hours to several visits, depending on the length of duct. We will ask where we can park in Stevenage and how to get equipment to the system, as those shape the visit.

  1. Diagnosis: a survey of the duct’s route, size and access.
  2. A fixed quote follows, based on what we found.
  3. We clean section by section, working from panel to panel.
  4. Bends, risers and the base of each riser get extra attention.
  5. Readings, photos and a recommended next clean date complete the job.

Before we arrive

  • Mention any sign-in, permit or induction we need
  • Plan for cooking equipment or plant to be off before we arrive
  • Tell us the best time to work, such as after service or at a weekend

What ductwork cleaning can’t fix

Ductwork cleaning cannot fix everything, and we’ll tell you before we start. It does not solve:

  • Ductwork that was poorly designed
  • Parts of the duct with no way in
  • Duct sections that need replacing

Not sure which it is? You can ring 0345 646 2711, or email photos and we will tell you honestly before you book.

Where we work

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

Leave it or put it right?

Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean straight away. Putting off the clean only pushes readings higher. If an insurer or inspector asks when the work was last done, an up-to-date certificate answers the question.

Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.

Why us?

  • Evenings, overnight and weekends, plus 24/7 emergency callout
  • Every visit written up, with pictures
  • Survey first, then a fixed quote
  • CHAS, SafeContractor and ISO 9001

Staff cleaning versus specialist work

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.

Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.

Between visits

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

  • Ask us about extra access panels where sections cannot be reached
  • Keep access panels clear of stored items
  • Have the grease measured if cooking hours go up
  • Never cook with a filter missing

Access panels are closed and sealed back up after cleaning, and the area around them is cleaned down. Waste grease and water are taken away.

Have access panels fitted where sections can’t be reached. It does not stop grease forming, but it stops it building unseen.

What ductwork cleaning looks like in Stevenage

Look up Stevenage on the FSA’s food hygiene register and you’ll find about 105 restaurants, cafés and works canteens and about 71 sandwich bars and takeaways in and around Stevenage, up to about a mile and a half out. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. It’s Stevenage council that sends environmental health officers to food businesses in Stevenage. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Hertfordshire Fire and Rescue Service covers Stevenage. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.

A hall kitchen that only cooks for events, whether near St Hugh & St John or elsewhere in Stevenage, still needs its extract cleaned, just less often. Healthcare kitchens, like those at hospitals such as Lister Hospital (about 1.7 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Historic houses near Stevenage, such as Aston Bury about 2.5 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
