About our extract fan cleaning in Kennington
In Kennington, as everywhere we work, the fan follows a set routine: isolated first, then opened, scraped and degreased. The result is photographed for your records. The work covers axial fans, roof-mounted fans and discharge points, and people most often call us about weak extraction at the canopy and a heavily greased fan housing.
Kitchens around a place like Kennington are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Kennington: your questions answered
Can you get to a site in Kennington?
Yes. Villages and rural sites across the South East are part of our work, Kennington included. Just mention lanes, gates or anything else about the site when you book.
Which fire and rescue service is responsible for Kennington?
Kennington is in the area of Kent Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Which accreditations do you hold?
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 carry full insurance.
Do we need to close while you work?
Not normally. Visits are timed for when the area is closed, such as overnight or at a weekend, so the site can carry on as normal.
Can you work evenings and weekends?
Yes, and that’s how we prefer to work. We book the visit for when the area is out of use, such as late evening, overnight or a weekend.
What makes a kitchen extract fan vibrate?
An unbalanced impeller, typically from uneven grease, is a common cause. We clean the fan and tell you if anything else, like worn bearings, is to blame.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
Does a TR19 kitchen extract clean cover the fan?
Yes. TR19® Grease covers the whole system, fan included. It’s isolated, opened and cleaned along with the canopy, plenum, filters, ducts and discharge.
For landlords and multi-site operators
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Looking after it afterwards
Once we have finished, these simple steps help:
- Keep access to the fan clear
- Watch for grease marks around the outlet
- Keep records of every fan clean
- Check the report shows the fan was cleaned
When we’ve finished, the fan is reassembled and run. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.
Run the fan throughout cooking. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.
How we price extract fan cleaning
Every site gets its own quote. These are the things that affect it:
- Travel, parking and unloading
- The number of sites or systems
- The size of the system
- Whether it’s a one-off visit or part of a schedule
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before any work starts.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- The times we could work without disrupting the site
- Where the site is and what kind of site it is
- Problems your staff have spotted
- Detail shots of panels, filters and grilles
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.
What we’re called out for in Kennington
By the time air reaches the fan, it has passed the canopy, filters and duct. The grease that is left lands on the blades and the casing where the spinning blades spread it around.
Signs it’s time to call us include:
- Grease stains around the discharge
- Hot, greasy smells near the fan
- Thick grease on the impeller and casing
- Vibration from an unbalanced impeller
Volunteers running a hall kitchen near Church of St Mary, or anywhere in Kennington, may not know when the extract was last cleaned, and a grease test settles it.
What your quote should include
- How they set the interval to the next visit
- Whether the figure could change on the day
- Which accreditations they hold, and whether you can check them
- Whether they’re fully insured
What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes an hour or two for most single fans, and we clear up before we go. For a place like Kennington, we load the van from the survey notes so the work can be done in one visit where possible.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- We clean the casing, the outlet and around the motor.
- The fan goes back into service with a report on its condition.
Preparing for the visit
- Let us know about permits to work or site inductions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Some systems can be priced from photos; others need a survey. 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.
Related advice
Different parts, different methods
Fan housings and motors
Some fans use a belt drive. Belts and pulleys are checked and cleaned where safe for your records.
Roof-mounted fans
Grease can escape from a roof fan onto the surrounding surface and we check the area around the outlet. Heavy staining is noted on the report.
Why act early in Kennington
A greasy fan has to work harder to move the same air. Less air is pulled from the kitchen, so heat and smoke linger, while the motor runs under more strain. A planned visit to Kennington fits your hours; an emergency does not.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Why book with us
- Fixed quotes, usually within one working day
- Full insurance on every job
- A single point of contact for sites across the South East and London
- Out-of-hours work and a 24/7 emergency line
