About our extract fan cleaning in North Oxford
A fan never collects grease in a neat, even layer. Uneven build-up unbalances the impeller, which brings vibration, noise and extra wear on the bearings and motor. A thorough clean removes the cause. Typical jobs include a fan left out of previous cleans and rough running from the extract fan, across centrifugal fans, in-line fans and axial fans.
Around a smaller place like North Oxford, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Do you need extract fan cleaning in North Oxford?
Grease condenses as the air cools, and on a roof or outside wall the fan can be in some of the coolest air in the system. So grease often settles heavily there.
It’s time to book a visit if you see:
- A fan that has never been cleaned
- A noisy fan that has got louder over time
- A heavily greased fan housing
- Fat spreading onto the roof or wall by the fan
A hospital like Acland Hospital, about 0.9 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Questions to ask before booking
- How VAT is shown on the quote
- Whether they’re fully insured
- Whether the whole system is included, or only the parts that are easy to reach
- Proof of accreditation you can verify
In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

What the work involves, part by part
Wall fans
Smaller kitchens may extract through a fan on an outside wall. We isolate it, then clean the blades and housing.
Inline duct fans
An inline fan can be easy to forget because it’s out of sight. We find it during the survey and include it in the clean.
For landlords and multi-site operators
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Do not turn the fan off mid-service
- File the fan’s report with your other records
- Book the fan into every full TR19 clean
- Keep the grease filters clean and in place
When the fan is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
Keep the whole system on its cleaning cycle. Regular full cleans keep the fan from building up heavy deposits, in line with BESA guidance.
Fixed quotes for extract fan cleaning in North Oxford
The survey tells us what the work involves. We look at:
- Parking and loading at the site
- The number of sites or systems
- One-off work versus a regular cycle
- How easy every part is to reach
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and the price is agreed before we start.
What to send for a quote
We can often survey from photos. The most useful are:
- Your last certificate, test record or report
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before any work starts.
Extract fan cleaning around North Oxford
Food Standards Agency records list about 89 cafés, restaurants and staff canteens and about 8 takeaways in and around North Oxford, up to about a mile and a half out. Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. In North Oxford, food businesses are inspected by environmental health officers from Oxford City council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for North Oxford is Oxfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you run catering at a historic house or estate in the area (Holywell Manor is about 1.5 miles south-east), event kitchens in older buildings often have awkward duct runs that need planning. Bursars and site managers at schools such as Oxford Academy tend to book extract cleaning for when the kitchen is empty.

The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes an hour or two for one fan, longer when it’s hard to reach. Because the survey comes first, a visit to North Oxford can usually be finished without a second trip.
- We start by checking where the fan sits and how to isolate it.
- The fan is isolated so it cannot start while we work.
- We remove the grease from the blades, impeller and casing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- The fan is put back into service, checked and photographed.
Getting ready for the visit
- Agree a time when the area can be out of use
- Name a contact who can let us in at the agreed time
- Clear the space around the work

North Oxford questions
Can you work in North Oxford outside opening hours?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. When you call 0345 646 2711 or email us, mention when the site is quiet.
Do you do school kitchen extract cleaning in North Oxford in the summer holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 51 schools, colleges and universities with registered kitchens within about a mile and a half of North Oxford. Booking early in the term gives the best choice of holiday dates.
What makes a kitchen extract fan vibrate?
A common cause is grease. Uneven build-up on the blades throws the fan off balance, causing vibration and noise. Cleaning may sort it, but worn bearings or a failing motor need a repair.
How much does extract fan cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll typically reply within one working day.
Do you have insurance?
Yes. Full insurance covers our work, and we have been trading since 2009.
What’s the cleaning interval for an extract fan?
At least as often as the rest of the extract, which BESA guidance sets by daily cooking hours: from 3-monthly for heavy use to 12-monthly for light use. A noisy or heavily coated fan may need it sooner.
Is it safe to clean the fan while the kitchen is open?
With the fan isolated, the extract is not running. That’s why fan cleans are done out of hours, and the kitchen is ready when we leave.
Can the fan be cleaned between full cleans?
Yes, if the fan needs it. We will often suggest checking the duct too, as a greasy fan usually means a greasy duct, but the choice is yours.
