Extract fan cleaning in Keston
The extract fan is the heart of the system: it pulls air from the canopy, through the duct and out of the building. Grease that gets past everything else ends up on its blades and housing, and that is what we clean. The work covers discharge points, in-line fans and centrifugal fans, and the jobs we see most are a fan motor running hot under a coat of grease and hot, greasy smells near the fan.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Keston, that normally means a longer system to clean and more access panels to plan around.
A written report with photos follows every visit, 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.

What affects the cost of extract fan cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The condition of the system
- How many systems or sites are involved
- Site rules, permits and inductions
- Access, including roofs, risers and ceiling voids
The cost depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.
What to send for a quote
To speed up the quote, send us:
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
- The times we could work without disrupting the site
- Any access panels or hatches you can see
The quickest way to a quote is to send pictures: 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.
Questions from Keston
Can you clean school kitchen extracts in Keston during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Keston. Just ring 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
Who carries out food hygiene inspections in Keston?
In Keston, it’s Bromley council that carries out food hygiene inspections. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
How much notice should we give?
Earlier is better, especially for out-of-hours work. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.
What if parts of the system can’t be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Can the fan be cleaned between full cleans?
Yes, we can clean just the fan. It’s useful when a fan is noisy or greasy between full cleans, but it doesn’t replace a full TR19 clean.
Leave it or put it right?
A fan clean in Keston does not take long: it takes a few hours where there are several fans or heavy deposits. Waiting adds vibration, wear and a harder clean. Planning ahead in Keston lets you pick a quiet night rather than lose a busy one.
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 work begins.

Different parts, different methods
Inline duct fans
An inline fan can be easy to forget because it’s out of sight. The survey makes sure it’s part of the clean.
Wall fans
With little duct before them, wall fans collect grease fast. They can need regular attention, which grease readings will show.
Extract fan cleaning in Keston: the local picture
The FSA’s food hygiene register shows about 15 restaurants, cafés and works canteens and about 5 takeaways within about 1.5 miles of central Keston. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Kitchens in Keston get their food hygiene inspections from Bromley council. 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. Most London extract cleaning happens at night, after the last service.
A hospital like Princess Royal University Hospital, about 1.1 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run a church or community hall kitchen, near Keston Parish Church or elsewhere in Keston, its extract still collects grease from every lunch and event.

For landlords and multi-site operators
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Do you need extract fan cleaning in Keston?
Fans that are hard to reach are often the ones that get missed. If it wasn’t included in past cleans, it may hold years of grease, and the report will show it.
Any of these means the system needs a check-up:
- An extract fan with no cleaning record
- Grease stains around the discharge
- Vibration from an unbalanced impeller
- A fan motor running hot under a coat of grease
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 2.2 miles south-east), access may need planning.

How the visit works
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and leave you the report. The visit itself takes an hour or two for one fan, longer when it’s hard to reach. For a job in Keston, tell us about loading bays, permits, lifts and roof access when you book.
- First we check the fan’s condition and how it sounds.
- Once isolated, we open the fan up.
- The impeller is cleaned blade by blade so it runs balanced.
- Housing, outlet and the area around the motor are cleaned.
- We run the fan and note its condition in the photo report.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Dig out any earlier paperwork for the system
- Let us know about parking and loading
