Extractor fans do a good job of removing moisture from the air in your room. This is particularly important in the bathroom and kitchen, where hot showers or delicious cooking causes lots of steam to rise. So if your extractor fan fails, it might not be long before you start to see damp and mould forming.

It’s important to get your extractor fan repaired as soon as possible to prevent damage to your home. But how much does it cost? We explain everything in this guide.

How much does it cost to repair an extractor fan?

Extractor fan repairs are generally affordable, with typical costs ranging between £50 and £150 depending on the type of fan and the fault. Kitchen extractor fans are often more expensive to repair than bathroom models due to their larger size and complex components.

Factors affecting the cost of extractor fan repair

• Type of extractor fan: Kitchen fans with advanced features or higher extraction rates cost more to repair than basic bathroom fans.
• Age of the fan: Older models may have discontinued parts, increasing repair costs.
• Nature of the fault: Issues with the motor or electrical wiring are more expensive to fix than filter or vent blockages.

Common extractor fan faults

There are a few common reasons for extractor fan breakdowns, and being able to give your repair specialist some information can help them identify the problem quicker and save you money. Here are the most common problems with extractor fans:

Reduced extraction rate

A fan struggling to remove steam or odours may have a clogged filter or blocked ductwork. Cleaning or replacing filters usually costs £50-£80, while ductwork repairs may cost £100-£150.

Excessive noise

Noisy fans often indicate worn bearings or loose mounting. Repairs for these issues typically range from £60-£120.

Running continuously

This could be caused by a faulty timer or humidity sensor, which may cost £80-£150 to replace.

Mould around fan

Mould growth is usually due to poor ventilation or leaks. Addressing this involves cleaning the fan and fixing leaks, costing around £50-£100.

Stops running completely

A non-functional fan often requires motor replacement, which can cost £100-£150. In some cases, replacing the entire unit might be more economical.

Do I need an electrician to repair an extractor fan?

For electrical issues such as wiring faults, motor failures, or replacing components like timers and sensors, you will need a qualified electrician. 

Most appliance repair specialists are qualified electricians. They can ensure the repair meets safety standards, particularly in areas like bathrooms where water exposure increases risks.

If the fault is mechanical, such as a clogged filter or vent, you may not need an electrician.

What is the life expectancy of an extractor fan?

Extractor fans typically last between 5 and 15 years, depending on usage and maintenance.

Bathroom extractors tend to have a longer lifespan with moderate use, while kitchen extractor fans or cooker hoods may wear out faster due to exposure to grease and cooking by-products.

You can extend the lifespan of your extractor fan by regularly cleaning it and ensuring you get it repaired as soon as you notice a fault.

Can I repair an extractor fan myself?

Simple repairs such as:

• Cleaning or replacing filters
• Tightening loose screws
• Checking for obvious blockages in the vents

Are relatively easy to do yourself using basic tools and the manufacturer's manual.

However, for electrical faults or motor replacements, it’s safer and more effective to hire a professional. Attempting complex DIY repairs can void warranties or risk further damage.

Is it worth repairing an extractor fan?

Repairing an extractor fan is usually worth it if:

• The fan is relatively new (under 10 years old).
• The repair cost is less than 50% of the price of a new fan.

For older fans or when repair costs are high, replacing the fan may be a more cost-effective option, especially as newer models are often more energy-efficient.

By repairing instead of replacing, you can save money and reduce waste, making it an eco-friendly choice.
