Chelsfield ductwork cleaning
Our technicians work in Chelsfield on cleaning of kitchen extract ductwork, horizontal runs and vertical risers through access panels. Out-of-hours visits, a fixed quote and a written report with pictures on every job.

Do you need ductwork cleaning in Chelsfield?
Wherever the kitchen is, in Chelsfield or elsewhere, the duct fills in the same way: daily cooking hours, the menu and the state of the filters. Under BESA guidance, the minimum interval is 3, 6 or 12 months, by daily cooking hours.
If you notice any of these, it’s worth a diagnosis:
- Thick deposits at the bottom of a vertical duct
- Years of grease along the duct floor
- Duct runs with no cleaning record
- High readings at a recent grease test
If you cook for passing trade around Chelsfield station, the extract can be cleaned between your last and first customer.
Questions to ask before you book
- Whether the quote shows VAT
- Whether the price is fixed
- When the next visit should be, and why
- Proof of accreditation you can verify
About our ductwork cleaning in Chelsfield
We’ve been trading since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, with each certificate issued through the BESCA portal. The work covers horizontal duct runs, bends and junctions and vertical risers, and people most often call us about fat dripping from the ductwork and thick crusts of old grease along the duct.
In a London area like Chelsfield, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

FAQs for Chelsfield
Do you clean school canteen extracts around Chelsfield out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Chelsfield, it pays to plan holiday dates ahead. Send us your term dates when you give us a ring on 0345 646 2711 or use the quote form, and we will fit the work in.
Which fire service covers Chelsfield?
It’s London Fire Brigade, which covers Chelsfield. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
Do I get a certificate for ductwork cleaning?
You get a photo report with before and after pictures, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. File them with the fire risk assessment.
How do you clean inside the ductwork?
We survey the route, test the grease, then open the access panels. Each run and riser is scraped and degreased, then the readings are repeated.
What happens if you can’t reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
What does ductwork cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before we start.
Chelsfield kitchens: local notes
There are about 17 restaurants, cafés and canteens and about 7 sandwich bars and takeaways across Chelsfield and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. The duct above a busy canopy coats itself in grease long before anyone sees it. Environmental health officers from Bromley council inspect food businesses in Chelsfield. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Chelsfield is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you run a church or community hall kitchen, near Church of St Martin of Tours or elsewhere in Chelsfield, its extract still collects grease from every lunch and event. Bursars and site managers at schools such as Chelsfield Primary School tend to book extract cleaning for when the kitchen is empty.

Part by part
Horizontal duct runs
Long horizontal runs need access panels at regular intervals. Any stretch out of reach is noted and can fit extra panels.
Vertical risers
Risers carry the extract up through the building to the roof. Grease collects on the walls and at the foot of the riser, which is one of the points we test.
Between visits
Results last longer with the right care. We suggest:
- Never cook with a filter missing
- Flag drips from the duct right away
- Keep to the interval on the report
- Have the grease measured if cooking hours go up
The report names every part of the duct that couldn’t be reached, with the reason. You can then decide whether to have access panels fitted.
Keep the fan on throughout service. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
When it’s something else
To be straight with you, some problems need a different fix:
- Fire dampers that do not close (they need testing and remedials)
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- Undersized or badly laid-out ducts
If you are not sure, just call us on 0345 646 2711, or email photos and we will give you a straight answer.

What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes a shift or more, depending on the length of the runs and the number of access points, and we clear up before we go. Night and weekend working is normal for us in London, and a site in Chelsfield is no exception.
- First we diagnose: the route, the access and the grease levels.
- You get a fixed price before work starts.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, photos and a recommended next clean date complete the job.
How to prepare
- Find the previous report, if there is one
- Clear the space around the work
- Make sure someone can let us in and lock up afterwards
Ask for a quote
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before work begins.
Advice
How we price ductwork cleaning
The survey tells us what the work involves. The main factors are:
- Parking and loading at the site
- Site requirements such as sign-in and permits
- Whether it’s a one-off visit or part of a schedule
- The times the site is available
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before we start.
What we need to know
You do not need the technical terms. Just send:
- A few general shots of the system
- How we’d reach plant on a roof or in a plant room
- Your last certificate, test record or report
- Your opening hours and when the area is out of use
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare in Chelsfield and across Greater London. Larger estates can be phased building by building around the people who use them.
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.
