Common problems we fix in Farringdon
Slow air leaves the most grease behind. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
Look out for these warning signs:
- Grease seeping out of the duct seams
- Ductwork that has never been cleaned
- Proof of duct cleaning for the insurer
- Years of grease along the duct floor
Commuter trade near Farringdon station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

About our ductwork cleaning in Farringdon
Grease in a duct is hidden, which is exactly why it’s dangerous. A flare-up drawn up from the range can light it, and fire can then run along the ductwork to other parts of the building. Cleaning the duct takes that fuel away. Typical jobs include duct runs with no cleaning record and grease leaking from duct joints, across vertical risers, bends and junctions and horizontal duct runs.
In a London area like Farringdon, 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, which is why keeping it clean to TR19® matters.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Ductwork cleaning in Farringdon: the local picture
The FSA’s food hygiene register shows about 3,786 restaurants, cafés and canteens and about 1,012 takeaways in and around Farringdon, up to about a mile and a half out. The duct above a busy canopy coats itself in grease long before anyone sees it. Farringdon sits within the area of 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. Overnight is the normal time to clean a London kitchen extract, so trading is not affected.
If you run catering at a healthcare site, such as a hospital like Finsbury Health Centre about less than half a mile north-west, the extract may need cleaning more often than a part-time kitchen. Term dates shape school work: for a school like Charterhouse Square School, an extract clean fits neatly into a half-term or summer break.
Farringdon is about 2 miles north of London, in Greater London. We carry out ductwork cleaning for commercial premises of every kind in Farringdon and the rest of Greater London. 764 places in Greater London are on our list, large and small.
Work in EC1V, EC1R and EC1P follows the same survey, fixed quote and written report as everywhere else we cover.

How we price ductwork cleaning
Sites vary more than people expect. What affects the quote:
- How many systems or sites are involved
- Where the site is and how we reach it
- Site requirements such as sign-in and permits
- Access, including roofs, risers and ceiling voids
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. Ask for a fixed quote and we will go through it with you.
What we need to know
To speed up the quote, please include:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- The postcode and the type of business
- Where the plant sits or the system leaves the building, such as a roof or outside wall
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 get going, give us a ring on 0345 646 2711, or email photos.
Why deal with it now?
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. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and why the quote is fixed before any work starts.

How the visit works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. The work itself takes a shift or more, depending on the length of the runs and the number of access points. Before any visit in Farringdon, 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.
- The duct is signed off with readings, photos and a next clean date.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms
Getting a quote
Photos are enough for some jobs, while others need a look on site. 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.
Advice
Multi-site and managed buildings
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 on a regular cycle.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Work can be phased by floor, building or site around the people who use them.
Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Consider fitting panels where the report shows gaps
- Book the next clean before the recommended date
- Run the extract fan throughout service
- File each certificate and photo report in the maintenance log
Any section of duct we couldn’t reach is listed on the report, with the reason. We can fit access panels so those sections are cleaned next time.
Run the extract the whole time the kitchen is cooking. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
Part by part
Attenuators and discharge
Attenuators, where fitted, quieten the extract, and their linings can soak up grease. We clean what can be reached and note anything that can’t.
Horizontal duct runs
A long flat run cannot be cleaned from one end. Any stretch out of reach is noted and can fit extra panels.
Farringdon questions
Who is the fire and rescue service for Farringdon?
That is London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can you come to Farringdon after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Farringdon doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
What shows that the ducts need a clean?
Signs include grease dripping from joints, smells and a fan working harder, but measuring is the reliable way to know. A WFTT or DTT reading gives a clear answer.
Are you insured?
Yes. Full insurance covers our work and have been trading since 2009.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Do I get a certificate for ductwork cleaning?
When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. The report shows readings, photos and any sections we couldn’t reach.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
