When your extractor fan stops working, it’s not just annoying-it’s a health risk. Moisture builds up, mold grows, and cooking smells stick to your walls and clothes. You don’t need to live with it. But who do you actually call? Not every handyman knows how to fix an extractor fan properly. And not every electrician is trained for kitchen ventilation systems. Here’s exactly who to contact, what they’ll do, and how much it should cost in 2026.
First, Rule Out the Simple Stuff
Before you call anyone, check three things yourself. You might save a service call.- Is the fan plugged in? Some extractor fans plug into a standard socket behind the cabinet. It might’ve been knocked loose during cleaning.
- Is the switch broken? Try flipping it on and off 5 times. If it clicks weakly or doesn’t click at all, the switch is likely dead.
- Is the filter clogged? Remove the grease filter and hold it up to the light. If you can’t see through it, clean it or replace it. A blocked filter forces the motor to overwork and burn out faster.
If those don’t fix it, you’ve got a real problem. Time to call in help.
Who Actually Fixes Extractor Fans?
Not all repair people are created equal. Here’s who you should call-and who to avoid.- Specialist extractor fan technicians: These are the best choice. They focus on kitchen ventilation systems. They’ve seen every model from Belling to Zephyr. They carry replacement motors, bearings, and control boards. They know how to test airflow and ducting without tearing your kitchen apart.
- Gas-safe registered engineers: If your extractor fan is part of a range hood above a gas hob, you need someone who’s Gas Safe registered. In the UK, it’s the law. A non-registered person can’t legally work on gas appliances-even if they’re just fixing the fan.
- Electricians with appliance experience: Some electricians fix fans. But many only do wiring. Ask if they’ve replaced a 120mm centrifugal motor before. If they say "I’ve done a few," ask for a photo of the last one they fixed. Real experience shows.
- General handymen: Avoid unless they specifically list extractor fan repair on their website. Most just tighten screws and say "it’s fixed." It’s not.
Look for companies that mention "kitchen extractor fan repair" in their service list. If they only say "appliance repair," they’re probably just swapping fridges.
What Happens During a Repair Visit?
A good technician won’t just show up with a toolbox. They’ll follow a clear process.- Diagnosis: They’ll turn the fan on, listen to the sound, check for vibrations, and test the airflow with a smoke pencil or tissue. A humming motor with no spin? That’s a capacitor issue. A screeching noise? Worn bearings.
- Inspection: They’ll remove the cover and check the motor, fan blade, wiring, and duct connection. They’ll look for grease buildup inside the housing-that’s the #1 killer of older fans.
- Quote: They’ll tell you if it’s repairable. If the motor’s seized or the PCB is fried, replacement is often cheaper. They’ll give you a fixed price before they start.
- Repair or replace: If they’re replacing the motor, they’ll use a branded part (like a TECO or ebm-papst). If they’re replacing the whole unit, they’ll match the size, CFM, and noise rating. No "close enough" fixes.
Any technician who skips the diagnosis or tries to upsell a new unit without testing the old one? Walk away.
How Much Does It Cost in 2026?
Prices vary by region, but here’s what you’ll pay in the UK right now.| Service | Average Cost | Includes |
|---|---|---|
| Diagnosis Only | £40-£60 | Inspection, report, quote |
| Motor Replacement | £120-£180 | Parts, labor, testing |
| Capacitor or Switch Replacement | £70-£110 | Parts, labor, 12-month guarantee |
| Full Unit Replacement | £250-£450 | Removal, new fan, ducting check, installation |
| Emergency Call-Out (Evenings/Weekends) | £100-£150 extra | Same-day service |
Watch out for companies charging over £200 just to replace a £15 capacitor. That’s a red flag. Reputable firms include parts and labor in one price. If they quote £80 for labor and £90 for parts, that’s fine. If they say "parts are extra," walk out.
What to Ask Before You Book
Don’t just pick the cheapest. Ask these questions.- "Are you Gas Safe registered?" (Mandatory if above a gas hob)
- "Do you carry replacement motors for my brand?" (Ask for the model number)
- "Do you offer a warranty on parts and labor?" (Expect at least 6 months)
- "Will you test the ducting for blockages?" (A blocked duct kills new fans fast)
- "Can I see your last three extractor fan jobs?" (A good tech will have photos)
Companies that hesitate or avoid these questions? They’re not serious about quality.
When to Replace Instead of Repair
Sometimes, repair isn’t worth it. Here’s when to buy new.- Your fan is over 12 years old. Motors wear out. Wiring degrades. Replacing parts on old units is like patching a leaky boat.
- The housing is cracked or rusted. Moisture has gotten inside. No new motor will last.
- You’re upgrading your kitchen. New fans are quieter, more efficient, and come with timers and sensors.
- The repair quote is over 60% of a new unit’s price.
Modern extractor fans cost £150-£400. They use 40% less energy than 2010 models. And they’re half as loud. If you’re staying in your home, replacing it now saves money long-term.
Where to Find Reliable Technicians in the UK
Start with trusted sources.- Gas Safe Register: Use their online tool to find registered engineers who do extractor fan work. Filter by "kitchen ventilation."
- Trustpilot: Search for "extractor fan repair [your town]". Look for companies with 4.5+ stars and 50+ reviews. Avoid those with "no reply" or "just charged me for a look."
- Local tradespeople directories: Check Checkatrade or RatedPeople. Filter for "appliance repair" with extractor fan experience.
- Ask your kitchen installer: If you had your kitchen fitted recently, they often have a trusted electrician they work with.
Never use someone you found on Facebook Marketplace. No insurance. No accountability. If they damage your kitchen, you’re stuck paying.
Prevent Future Breakdowns
Once it’s fixed, keep it running.- Clean the grease filter every 2 weeks. Wash it in hot, soapy water. Let it dry fully before putting it back.
- Check the ducting once a year. Pull the fan off and look inside. If you see thick grease or dust, call a pro to clean the duct.
- Run the fan for 10 minutes after cooking. Even if you don’t smell smoke, moisture is still rising.
- Don’t use it as a dehumidifier. If you’re drying clothes under it, you’re overloading the motor.
A well-maintained extractor fan lasts 15+ years. Neglect it, and it’ll die in 5.
Can I fix my extractor fan myself?
You can handle simple tasks like cleaning the grease filter or replacing a blown fuse. But if the motor isn’t spinning, the switch is dead, or the fan is humming but not moving air, you need a professional. Extractor fans have capacitors that store dangerous voltage-even when unplugged. A mistake can fry your circuit board or give you a shock. Leave internal repairs to certified technicians.
Why is my extractor fan so noisy all of a sudden?
A sudden increase in noise usually means one of two things: worn bearings in the motor, or a loose or bent fan blade. Grease buildup can also cause imbalance. A technician will spin the motor by hand-if it grinds or wobbles, the motor needs replacing. If the blade hits the housing when spinning, it’s bent and must be swapped. Don’t ignore the noise. It’s the fan screaming that it’s about to fail.
Do I need a new duct if I replace the fan?
Not always. If the duct is made of rigid metal, is clear of debris, and isn’t crushed or kinked, you can reuse it. But if it’s flexible plastic, covered in grease, or has more than two 90-degree bends, it’s a bad design. Modern fans need smooth, short duct runs to work properly. A good technician will test airflow and recommend a duct upgrade if needed. Don’t install a new fan into an old, clogged duct-it’ll die fast.
My fan works but smells like burning plastic. What’s wrong?
That smell means the motor’s overheating. It could be a failing capacitor, a blocked duct, or a motor that’s running too hard because the fan is clogged. Turn off the fan immediately. Don’t use it again until a technician checks it. Continuing to run it could cause a fire. This isn’t a "wait and see" situation.
Is it worth repairing an old extractor fan?
It depends. If your fan is under 8 years old and the repair cost is under £120, yes. But if it’s older than 12 years, or the repair is over £150, replacement is smarter. New fans are quieter, use less energy, and come with smart features like humidity sensors and timers. You’ll save money on electricity and avoid another breakdown in 6 months. Think long-term, not just short-term cost.
