Extract fan cleaning in Kennington, done properly
Every kitchen extract depends on its fan: it pulls air from the canopy, through the duct and out of the building. Whatever grease slips past the filters and duct reaches the fan and we clean it off. If you have grease escaping from the fan outlet and a heavily greased fan housing, we can help.
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.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

How we price extract fan cleaning
Sites vary more than people expect. The main factors:
- The size of the system
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
- How easy every part is to reach
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.

When you call or email, these details help:

Grease, kitchens and Kennington
There are about 19 restaurants, cafés and canteens and about 6 sandwich bars and takeaways in and around Kennington, up to about a mile and a half out, according to the Food Standards Agency’s register. Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. It’s Vale of White Horse council that sends environmental health officers to food businesses in Kennington. 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. Kennington is covered by Oxfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Holywell Manor is about 3.1 miles north), access may need planning. For schools such as St Swithun's CofE Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
Kennington is about 3 miles south of Oxford, in Oxfordshire. We carry out extract fan cleaning for commercial premises of every kind in Kennington and the rest of Oxfordshire. Across Oxfordshire, we cover 443 places, and Kennington is one of them.

What we’re called out for in Kennington
A fan in Kennington builds up grease at a rate set by the kitchen, not the location: daily hours and the amount of frying and grilling. Under BESA guidance, the whole system, fan included, needs cleaning at least every 3, 6 or 12 months depending on daily hours.
Keep an eye out for any of the following:
- A fan that hums, whines or rumbles
- Fat spreading onto the roof or wall by the fan
- Grease around the motor and its mounts
- Thick grease on the impeller and casing
A hall kitchen that only cooks for events, whether near St Swithun's Church or elsewhere in Kennington, still needs its extract cleaned, just less often.
What to look for in a quote

- Whether inaccessible sections are listed on the report
- If they look at the system before pricing
- When the next visit should be, and why
Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
What extract fan cleaning can’t fix
Before booking, it helps to know what’s not included:
- A faulty speed controller or isolator
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
- A fan that’s too small for the system (a design question)
If you’re not sure, just give us a ring on 0345 646 2711 or drop us a line and we will give you a straight answer before booking.

How the visit works
Every visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, clear away and leave you the report. On site, the work takes a couple of hours per fan, depending on its size and the build-up. Tell us when your site near Kennington is quiet and the visit will be booked for then.
- We find the fan and check how it’s reached and how it’s isolated.
- With the fan isolated, the housing is opened.
- The impeller and the housing around it are scraped clean.
- We degrease the fan and housing, taking care around the motor.
- The fan is put back into service, checked and photographed.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any sign-in, permit or induction we need
- Name a contact who can let us in at the agreed time
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Between visits
Results last longer with the right care. We suggest:
- Make sure the fan is included each time
- Flag smoke lingering at the canopy
- Keep access to the fan clear
- Report rattles or humming early
The photo report shows the fan before and after cleaning. It lists what was cleaned and anything we couldn’t reach, along with the recommended next clean date.
Stick to the interval for the full extract. Regular full cleans keep the fan from building up heavy deposits, in line with BESA guidance.
What happens if it’s left?
A fan that sounds rough in Kennington is often telling you the extract needs a clean. If the fan is coated, the duct before it usually is too, so it’s worth checking the whole system. It’s better to plan the work at a site near Kennington than wait for a failure.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.

Kennington: your questions answered
Can the work in Kennington be done at night or at weekends?
Yes, nights and weekends are routine for us. That way a site in Kennington doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Who enforces fire safety at workplaces in Kennington?
That is Oxfordshire Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Is it safe to clean the fan while the kitchen is open?
It has to be off and isolated before anyone touches it. Cleans are done when the kitchen is closed, so cooking isn’t affected.
Where does the waste go?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Do you look at the system first?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
How often should the extract fan be cleaned?
With the whole system, at intervals set by BESA guidance: every 3, 6 or 12 months. Some fans need attention sooner.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Ring any time and tell us what’s happened.
