Extract fan cleaning in Walworth, Greater London

Why it’s worth doing now in Walworth
A greasy fan has to work harder to move the same air. Airflow at the canopy drops and the kitchen gets hotter and smokier, while the motor runs under more strain. For a site in Walworth, fitting the work in overnight now is far easier than closing at short notice later.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.

Extract fan cleaning for kitchens and businesses in Walworth
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. The work covers centrifugal fans, fan housings and axial fans, and common reasons people get in touch are fat spreading onto the roof or wall by the fan and a fan that hums, whines or rumbles.
In London, few kitchens can spare a day to close, so extract cleaning in Walworth is usually done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Multi-site and managed buildings
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 are happy to quote for all of it.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Different parts, different methods
Impellers and blades
A clean impeller shows any damage: chips, distortion or wear. Anything we see goes on the report.
Inline duct fans
Space around an inline fan can be tight, so the method is planned in advance. Anything out of reach is recorded.

Do you need extract fan cleaning in Walworth?
The fan sits at the end of the grease’s journey. Whatever grease is still in it settles on the impeller and inside the housing, and the spinning blades fling it onto the walls of the housing.
Clients normally contact us when they notice one of these:
- A fan coated in grease inside its housing
- A fan shaking on its mounts
- Grease stains around the discharge
- A noisy fan that has got louder over time
Volunteers running a hall kitchen near Lady Margaret Church, or anywhere in Walworth, may not know when the extract was last cleaned, and a grease test settles it.

Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Extract fan cleaning in Walworth: the local picture
Food Standards Agency records list about 1,139 restaurants, cafés and canteens and about 601 takeaways and sandwich shops in Walworth and the streets around it, up to about 1.5 miles out. The fan at the end of each of those extracts collects grease that slows it and wears the motor. London jobs typically start after the last service, with loading and roof access agreed with the building first. The fire and rescue service for Walworth is 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.
School kitchens, at schools like Robert Browning Primary School for example, are normally cleaned in the holidays so no lunches are lost. Commuter trade near Elephant & Castle station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

FAQs for Walworth
Can you come to Walworth after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Walworth doesn’t have to lose a day’s trading. Let us know the hours you are closed and we will book within them.
Does London parking affect a job in Walworth?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, usually makes it simpler.
What happens if you can’t reach some of it?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
Who is the responsible person?
That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
How often should the extract fan be cleaned?
It depends on how many hours the kitchen cooks in BESA guidance. At the extremes, that is 3-monthly for heavy use and 12-monthly for light use, fan included.
Do you offer extract fan cleaning separately?
Yes, where it makes sense. A coated fan often means the duct before it is coated too, but the choice is yours.
Is the fan isolated during cleaning?
We isolate the fan, so the kitchen cannot cook while we work. That’s why fan cleans are done out of hours, and the kitchen is ready when we leave.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Fixed quotes for extract fan cleaning in Walworth
Your quote is based on your site. We consider:
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
- The number of sites or systems
- The condition we find in the survey
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
What we need to know
We can often survey from photos. The most useful are:
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- Any symptoms, from odd noises to smells or leaks
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before any work starts.
How the visit works
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a couple of hours per fan, depending on its size and the build-up. Loading bays, visitor permits and roof access are the first things we ask about for a site in Walworth.
- We find the fan and check how it’s reached and how it’s isolated.
- The fan is isolated so it cannot start while we work.
- The impeller and the housing around it are scraped clean.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- The fan is put back into service, checked and photographed.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet
- Move anything stored near the system
