Extract fan cleaning for kitchens and businesses in Single Street
Cleaning removes grease, not wear. Anything that looks worn or damaged goes on the report, and we also repair and replace extract fans. You’ll know whether the fan just needed cleaning or something more. The work covers discharge points, axial fans and fan housings, and people most often call us about a fan that hums, whines or rumbles and fat spreading onto the roof or wall by the fan.
In a London area like Single Street, 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.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Fixed quotes for extract fan cleaning in Single Street
Every site gets its own quote. These are the things that affect it:
- The condition of the system
- Travel, parking and unloading
- Site rules, permits and inductions
- The times the site is available
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.
What to send for a quote
What to send for a quote:
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
- Any previous report or certificate
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
The process
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes a few hours where there are several fans or heavy deposits, and the area is cleaned down before we leave. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Single Street.
- The fan is found and its type, access and isolation checked.
- We isolate the power before opening the housing.
- Grease is scraped off the impeller blades and casing.
- Blades, housing and surrounds are degreased with care around the electrics.
- We reassemble, run and photograph the fan.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Clear loose items from the work area
- Tell us about site rules, permits or sign-in
Getting a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To start, ring 0345 646 2711 or drop us a line.

When to call us in Single Street
Poor filters mean a greasier fan. Missing, damaged or badly fitted filters let grease travel the whole system, so the fan takes far more than it should.
Common reasons sites call us include:
- A fan that has never been cleaned
- Grease stains around the discharge
- Rough running from the extract fan
- A motor area thick with grease
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Princess Royal University Hospital is the nearest hospital to Single Street, about 3.3 miles north.
What your quote should include
- Whether a survey comes first
- What insurance they carry
- Exactly which parts of the system are covered
- How they set the interval to the next visit
Leave it or put it right?
A fan clean in Single Street does not take long: the work takes a few hours where there are several fans or heavy deposits. Waiting adds vibration, wear and a harder clean. London sites work long hours, and the longer a job is left, the bigger it gets.
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 any work starts.

What should I send you?

How much does extract fan cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, normally ready within one working day.
Do we need to close while you work?
Not typically. Visits are timed for when the area is closed, such as overnight or at a weekend, so the site can carry on as normal.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
When it’s something else
Not every problem is solved by extract fan cleaning, and we will tell you before we start. It does not solve:
- A fan that’s too small for the system (a design question)
- Electrical faults in the fan’s supply or controls (an electrician’s job)
- A motor that has burnt out
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we’ll tell you honestly.

Single Street kitchens: local notes
The FSA’s food hygiene register shows about 10 restaurants, cafés and works canteens within 1.5 miles or so of the middle of Single Street. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. It’s Bromley council that sends environmental health officers to food businesses in Single Street. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after. Single Street sits within the area of London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
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 mile north-west), access may need planning. Where a hall near Church of St Peter and St Paul, or anywhere in Single Street, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Part by part
Kitchens with long cooking hours
When a busy kitchen’s fan fails, cooking stops. Keeping the fan clean is part of avoiding that, and our 24/7 emergency callout is there if it happens anyway.
Fan housings and motors
The housing around the impeller catches grease flung off the blades. We clean it along with the blades.
