Our technicians work in Herne Hill on repair and replacement of kitchen extract fans, fan motors and worn fan parts. Fixed quotes, work around your opening hours and photo reports as standard.

- A fan that won’t start at all
Part by part
Roof and wall-mounted fans
Many kitchen extract fans sit on a roof or an outside wall. Access affects how long a repair takes and we plan around it.
Impellers and housings
Where an impeller is bent or corroded, cleaning won’t help. It may be replaced on its own, or with the whole fan.
Extract fan repair in Herne Hill
We treat a failing fan much like a patient: we hear the symptoms, find the cause and put it right. What you want back is a fan that runs smoothly and a clear explanation of what was done. The work covers bearings, fan motors and kitchen extract fans, and people most often call us about a humming noise from the fan motor and vibration spreading from the fan into the ducts.
For a London kitchen, a failed extract fan typically means the cooking stops. Fans in Herne Hill are often on a roof or in a basement at the end of a long duct run, so access is the first thing we ask about.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Herne Hill questions
Who carries out food hygiene inspections in Herne Hill?
Kitchens in Herne Hill are inspected by Southwark council’s environmental health officers. A note of when the fan failed and when it was fixed shows the problem was dealt with.
What if my kitchen extract fan stops in Herne Hill at night?
Day or night, a failed fan in Herne Hill can be reported on our emergency line. Phone 0345 646 2711 and we will talk through the fault and access. Tell us where the fan is and how to reach it.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
How long does an extract fan repair take?
Most fan jobs take an hour or two to diagnose, then longer if parts or a new fan are needed, including testing. We plan the work around your service wherever we can.
Can you tell me the price of a fan repair?
The price depends on the diagnosis. After we have checked the fan, we give you a fixed price for the repair or the replacement.
Are you fully insured?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
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 carry full insurance.
Is repair an option before replacing the whole fan?
In many cases, yes. Many faults are fixed by cleaning the impeller or renewing worn parts and we only recommend replacement when repair does not make sense.

What happens if it’s left?
Weak extraction leaves heat, smoke and fumes in the kitchen. The kitchen becomes an uncomfortable place to work and grease has more chance to settle on surfaces and in the duct. In Herne Hill, as across London, ductwork often passes through shared risers and other people’s space.

Advice
What a clean won’t put right
In fairness, some problems need a different fix:
- Grease build-up in the rest of the extract system
- Gas interlock faults that a Gas Safe registered engineer must deal with
- A system that needs redesigning rather than repairing
Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we’ll tell you honestly.

Aftercare tips
Once we have finished, these simple steps help:
- Keep the area around the fan controls clear
- Report new noises from the fan early
- Keep a record of any trips or stoppages
- Make sure every filter is in place and clean
Before we leave, the fan is run and checked. You will hear what we found and what we did along with anything else that needs watching.
When filters block, the fan works harder. Keeping filters clean eases the strain and helps prevent overheating.
Landlords, agents and facilities managers
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Extract fan repair in Herne Hill: local notes
Look up Herne Hill on the FSA’s food hygiene register and you will find about 439 restaurants, cafés and works canteens and about 249 sandwich bars and takeaways in and around Herne Hill, up to about a mile and a half out. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. Environmental health officers from Southwark council inspect food businesses in Herne Hill. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. That is one more reason not to keep cooking with a broken fan. A failed fan in a London kitchen typically means a closed kitchen, so access details help us plan the repair.
If you manage a school such as Judith Kerr Primary School and the kitchen fan is getting louder, the next break is the time to deal with it. A fan that rarely runs, like one in a hall kitchen near Saint Faith's or elsewhere in Herne Hill, can seize between uses. If you run a café or takeaway near North Dulwich station, a failed fan in the middle of service is exactly what our 24/7 emergency line is for.

- Access, including roofs, risers and ceiling voids
- Working hours and out-of-hours timing
- One-off work versus a regular cycle

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or email us and we will give you an honest view and a fixed quote.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- The paperwork from the last visit, if you have it
- Your opening hours and when the area is out of use
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
