Extract fan cleaning in Biggin Hill, Greater London
Need extract fan cleaning in Biggin Hill? We diagnose first, fix the price and book the work around your hours, then sign off with a report and pictures.
- Burning smells from the fan area
- An extract fan that vibrates or rattles
- A noisy fan that has got louder over time
What we do, step by step
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes an hour or two for one fan, longer when it’s hard to reach. We fit London jobs around the building rather than the other way round, so a visit in Biggin Hill is normally out of hours.
- The fan is found and its type, access and isolation checked.
- We isolate the power before opening the housing.
- We scrape the heavy grease from the blades and housing.
- Blades, housing and surrounds are degreased with care around the electrics.
- It’s closed up, run, checked and photographed for the report.
Before we arrive
- Arrange a key holder or contact on site
- Find the previous report, if there is one
- Tell us about site rules, permits or sign-in

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.

How we handle extract fan cleaning in Biggin Hill
Any fan serving a kitchen in Biggin Hill is cleaned the same careful way as anywhere else: we isolate it, open the housing, scrape the impeller and degrease the lot. The result is photographed for your records. We are often asked to deal with an extract fan with no cleaning record and a fan motor running hot under a coat of grease, on centrifugal fans, discharge points and fan housings.
In a London area like Biggin Hill, 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.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Biggin Hill kitchens: local notes
The FSA’s food hygiene register includes about 3 pubs and bars within 1.5 miles or so of the middle of Biggin Hill. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Food hygiene inspections in Biggin Hill are the job of Bromley council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand. London Fire Brigade covers Biggin Hill. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Healthcare kitchens, like those at hospitals such as Warlingham Park Hospital (about 2.7 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Down House is about 1.7 miles north-east), access may need planning.
Biggin Hill is about 6 miles east of Caterham, in Greater London. Every kind of commercial site in Biggin Hill, extract fan cleaning is something we can help with. Visits can be booked for evenings, overnight or weekends so the site keeps running. Across Greater London, we cover 764 places, and Biggin Hill is one of them.

What else we do in Biggin Hill
Biggin Hill: your questions answered
Can you work in Biggin Hill outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in Biggin Hill does not have to lose a day’s trading. Let us know the hours you are closed and we will book within them.
Who is the fire and rescue service for Biggin Hill?
It’s London Fire Brigade, which covers Biggin Hill. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Who is the responsible person?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Can you fix a fan that is worn out?
A clean won’t mend wear. We repair and replace extract fans as well, with a fixed quote first.
Do you look at the system first?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. A fixed quote follows.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Managing agents and facilities teams in Biggin Hill
Facilities teams in offices, schools and healthcare sites book us too in Biggin Hill and across Greater London. Work can be phased by floor, building or site to keep disruption down.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
When to call us in Biggin Hill
A greasy fan in Biggin Hill is fuel at the end of the duct. A fire in the duct can reach the fan and the grease around it and an overworked motor runs hotter.
It’s time to book a visit if you see:
- A motor area thick with grease
- A smell of hot grease from the extract
- A fan coated in grease inside its housing
- Fat spreading onto the roof or wall by the fan
Term dates shape school work: for a school like Oaklands Primary Academy, an extract clean fits neatly into a half-term or summer break.
Questions to ask before booking
- What records you’ll receive afterwards
- What hours they’ll be on site
- What insurance they carry
- Whether they recommend a next date
Between visits
Here’s the after-treatment advice, in brief:
- Listen for new noises or vibration from the fan
- Don’t turn the fan off mid-service
- File the fan’s report with your other records
- Make sure the fan is included each time
The photo report shows the fan before and after cleaning. It notes what was done and anything that couldn’t be reached, along with the recommended next clean date.
Fewer grease particles reaching the fan means less build-up. Keep the grease filters clean, fitted and in place, and replace any that are damaged.
Honest limits
In fairness, some problems need a different fix:
- An undersized fan that cannot cope
- A faulty speed controller or isolator
- Grease in the canopy and ductwork
If in doubt, phone us on 0345 646 2711 or use the quote form and we’ll say what we think.
Where we work
- Roof-mounted fans
- Centrifugal fans
- Axial fans
- In-line fans
- Fan housings
- Discharge points
Leave it or put it right?
Without a working extract fan, a kitchen can’t cook safely. Grease is often where fan trouble begins, so cleaning the fan helps keep it working. We also offer a 24/7 emergency callout if the worst happens. A busy site in Biggin Hill builds up dirt and wear quickly, so putting it off makes the eventual job larger.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
In-house cleaning and specialist cleaning do different jobs. 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.
