Extract fan repair in Stockwell
Diagnosis comes before parts. We look at the motor, the belts or direct drive, the impeller and the mountings, along with the fan’s controls. After that, you get a fixed price for what’s needed. The work covers bearings, kitchen extract fans and fan motors, and the jobs we see most are a squealing belt on start-up and a fan that whines, hums or grinds.
In London, getting a new fan to the roof or plant room can take planning, and in Stockwell, parking and lifting are part of that. Repairs can be done out of hours so the kitchen keeps trading.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Part by part
Motors and bearings
An overheating motor is a warning sign. The cause might be grease restricting the airflow, or the motor itself may be failing.
Direct-drive fans
Many kitchen extracts use direct-drive fans. When the motor fails, replacing the whole fan unit can make more sense than repairing it, and we’ll explain why.
What we do, step by step
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a few hours on site, depending on the fault and the access to the fan. Night and weekend working is normal for us in London, and a site in Stockwell is no exception.
- We agree a time to attend, out of hours if needed.
- We isolate the extract and open the fan housing.
- Bearings, drive, impeller, motor and mounts are inspected.
- You hear whether repair or replacement makes sense, with a fixed quote.
- The fan is repaired or replaced, then checked running.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Clear loose items from the work area
- Mention any parking or loading restrictions
Getting a quote
We don’t publish a price list, because every site is different. We look at your system first, from photos or on a visit, and then give you a fixed quote. To start, give us a ring on 0345 646 2711, or send details by email.
Advice
Extract fan repair around Stockwell
Food Standards Agency data counts about 589 restaurants, cafés and canteens and about 265 sandwich bars and takeaways in and around Stockwell, up to about a mile and a half out. Those that cook under a canopy rely on a fan that runs every hour they’re open. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement. Food hygiene inspections in Stockwell are the job of Lambeth council’s environmental health team. Food hygiene rules expect food premises to have suitable and sufficient ventilation. Getting the fan running again is the priority.
If you cook near Brixton station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early. Hall kitchens near St. Andrew's, or anywhere around Stockwell, often use their fans only now and then, and an idle fan can stick.
Stockwell is about 2 miles south-west of London, in Greater London. From the centre of Stockwell to the outskirts, extract fan repair is available to all kinds of commercial premises, from a single unit to a large public building. Our Greater London coverage runs to 764 places, Stockwell among them.
All of SW9, SW4 and SW8 is within our area for extract fan repair, from busy streets to back roads. If you need extract fan repair at premises on Kay Road, West Road and Cato Road or anywhere close by, we can help. You’ll find Stockwell on the A203 and A2217, so it’s easy for us to get to for out-of-hours visits. We also cover the places around Stockwell: Little Portugal (1 mile north), Angell Town (1 mile east), North Brixton (1 mile north-east), South Lambeth (1 mile north) and Clapham (1 mile west).

What’s near Stockwell
Locally, jobs take us to businesses close to Max Roach Park, Lansdowne School and The Marquess Of Lorne Public House, among other places. Stockwell’s nearest station is Brixton station, roughly 0.5 miles south-east. Nearby you will also find Gabriel's Wharf (2.8 miles north) and Baynard's Castle (3.1 miles north). For a walk, there’s Knight's Hill and Centre for Wildlife Gardening.
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Tell us about a new rattle or whine straight away
- Don’t turn the fan down to hide a noise
- Make sure every filter is in place and clean
- Do not cook with gaps in the filter bank
If the fan had grease on it, the rest of the system almost certainly does too. A full TR19® clean deals with the canopy, ductwork and fan together and you get a TR19 certificate and photo report afterwards.
A slipping belt or a loose mount is a small job. Ignored, they can lead to bigger failures, so it’s worth acting early.
Honest limits
It’s worth knowing the limits before booking:
- Smells from the discharge that need odour control equipment
- Wiring and supply faults beyond the fan itself
- Ductwork designed too small for the kitchen’s cooking
If in doubt, call 0345 646 2711 or email us and we’ll say what we think before you book.

How we price extract fan repair
The survey tells us what the work involves. We look at:
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
- The condition we find in the survey
- The scale of the work
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- A few general shots of the system
- How we’d reach plant on a roof or in a plant room

What happens if it’s left?
A noisy fan rarely fixes itself. Worn bearings can seize without much warning, and that often happens mid-service. A repair booked now is simpler than an emergency later. A booked night’s work in Stockwell costs you no trading time; an unplanned closure does.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.

When to call us in Stockwell
Some faults are in the controls rather than the fan. Speed controllers, isolators and wiring can all fail so we check the controls before blaming the motor.
Most sites get in touch when they notice something like this:
- A fan shaking on its mountings
- A fan worn beyond sensible repair
- An overheating extract motor
- An extract fan that has stopped working
If you run a school kitchen, at a school such as St Andrew's Church of England Primary School or nearby, a fan that’s getting noisy is best repaired in the holidays before it fails in term.

Common questions in Stockwell
Can the work in Stockwell be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. It means the site in Stockwell keeps running as normal. Just ring 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Who carries out food hygiene inspections in Stockwell?
The local authority for Stockwell is Lambeth council, and its environmental health team does the inspecting. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
Will we have to shut during the visit?
Not usually. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages so parts stay in use.
Do you recommend a next date?
Yes. The report recommends when the next visit should be, based on use and what we found.
What paperwork should we keep on file?
Visit reports, certificates and your in-house cleaning logs. Insurers, fire officers and EHOs may all ask to see them, so keep them together and easy to find.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How long will the fan be out of action?
Most fan jobs take an hour or two to diagnose, then longer if parts or a new fan are needed, including testing. We will fit it around the kitchen’s hours where possible.
