Part by part
Horizontal duct runs
Flat runs of duct link the canopy to the riser or the outside wall. Grease drops out of the slowing air along them, so each section is cleaned through its access panels.
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We reach it from the plenum side where possible.
Ductwork cleaning for kitchens and businesses in Chelsea
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Grease settles along every metre of it, and that is where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. The work covers multi-storey ducts, horizontal duct runs and vertical risers, and common reasons people get in touch are gaps where access panels were never fitted and heavy grease at the base of a riser.
In a London area like Chelsea, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. 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.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings
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.
Facilities teams in offices, schools and healthcare sites book us too in Chelsea and across Greater London. Larger estates can be phased building by building to keep disruption down.
Signs you need ductwork cleaning in Chelsea
Grease in a duct running from a kitchen in Chelsea is as much a fire risk as in any building. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
The symptoms we are asked about most include:
- Proof of duct cleaning for the insurer
- Thick deposits at the bottom of a vertical duct
- A grease test showing the duct is overdue
- Smells of old cooking grease from the ductwork
If your kitchen is in a listed or historic building, like the houses around Chelsea (Carlyle's House is about 0.4 miles south-west), fitting access panels needs care.

Aftercare tips
Think of this as the after-treatment advice, in brief:
- Keep your cleaning records together
- Keep access panels clear of stored items
- Ask us about extra access panels where sections can’t be reached
- Keep to the interval on the report
You’ll have a recommended date for the next clean, based on the readings and your daily cooking hours, in line with BESA guidance.
Keep to the cleaning interval on the report. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
Your questions about ductwork cleaning in Chelsea
Can a school canteen extract in Chelsea be done out of term time?
Yes, holiday work suits schools best. There are about 65 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Chelsea. Send us your term dates when you phone us on 0345 646 2711 or send us an email, and we will fit the work in.
Who inspects food businesses in Chelsea?
Food hygiene inspections in Chelsea are carried out by Kensington and Chelsea council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you cover Chelsea?
Yes. Our technicians work in Chelsea, as part of our area across London and the South East.
What information do you need?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply call us on 0345 646 2711 or drop us a line.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
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 do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes a shift or more, depending on the length of the runs and the number of access points. Before any visit in Chelsea, we agree where the van can stop and how equipment reaches the system.
- Diagnosis: a survey of the duct’s route, size and access.
- You get a fixed price before work starts.
- Each section is cleaned in turn through its access panel.
- Bends, risers and the base of each riser get extra attention.
- Readings, photos and a recommended next clean date complete the job.
Getting ready for the visit
- Agree a time when the area can be out of use
- Name a contact who can let us in at the agreed time
- Mention any parking or loading restrictions
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Why act early in Chelsea
Fire inside a duct is out of sight and out of reach. It can travel through the ductwork to other parts of the building, which is why the duct matters as much as the canopy. In Chelsea, as across London, ductwork often passes through shared risers and other people’s space.
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

Ductwork cleaning around Chelsea
There are about 1,391 restaurants, cafés and canteens and about 158 sandwich bars and takeaways in and around Chelsea, up to about a mile and a half out, according to the Food Standards Agency’s register. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. London jobs usually start after the last service, with loading and roof access agreed with the building first. Environmental health officers from Kensington and Chelsea council inspect food businesses in Chelsea. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Where a hall near Former Welsh Congregational Church, or anywhere in Chelsea, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Chelsea is Royal Brompton Hospital, about under half a mile west.
