Fix an extractor fan
Trade: Electrician
⭐ Introduction
An extractor fan helps improve ventilation in your home by removing excess moisture, cooking odours, and stale air. They’re commonly fitted in kitchens, bathrooms, utility rooms, or anywhere dampness or lingering smells might be a problem.
Fixing an extractor fan might become necessary if it stops working altogether, makes unusual noises, or doesn’t vent properly. Timely repairs can prevent issues like mould growth, condensation damage, and poor indoor air quality.
If you notice your extractor fan is faulty or underperforming, it’s worth arranging a qualified electrician to inspect and repair it, ensuring safe and effective operation.
🔧 What the job involves
Fixing an extractor fan usually means the electrician will:
- Inspect the unit to identify the cause of the fault (e.g. electrical failure, motor issue, wiring problem)
- Test electrical connections and ensure compliance with current wiring standards (Part P of the Building Regulations covers electrical safety in dwellings)
- Replace any faulty components such as the fan motor or switch
- Check the ducting or ventilation route, making sure air can flow freely outside
- Confirm the fan is correctly wired, earthed, and switched
- Test the fan to ensure it runs smoothly and efficiently after the fix
- Clean or advise on maintaining the fan for future reliability
If the fan is very old or extensively damaged, a replacement may be recommended instead of a repair.
📝 Step-by-step from booking to completion
- Initial enquiry: Contact a local qualified electrician—check for Part P registration or membership of a trade body.
- Survey and quote: The electrician will visit your home to inspect the fan and diagnose the issue. They’ll provide a clear quote for repair, including labour and parts.
- Agree and schedule: You agree a date and time for the repair work.
- Day of work: The electrician arrives on time, repairs or replaces faulty parts, tests electrical safety, and ensures correct operation.
- Completion and demo: They explain any work done, advise on maintenance, and provide receipts or any required certification.
- Aftercare: Keep the paperwork safe and follow any recommended fan cleaning or servicing to help prolong its life.
💷 Main costs to expect
- Labour: Typically £60–£100 per hour including VAT.
- Parts: Replacement motors, switches, or controls might cost £30–£100 depending on the fan type.
- Materials: Minor wiring or installation materials could add £10–£20.
- Disposal: Minimal charge or included in labour.
- Certification: Usually, no separate cost unless electrical rewiring or new parts require an Electrical Installation Certificate.
Example itemisation
- Labour (1 – 2 hours): £80
- Fan motor replacement: £50
- Minor wiring materials: £15
- Total estimated cost: £145 (including VAT)
📊 What affects the price
- Access to the fan (easy-access ceiling fan vs. tight loft or wall space)
- Complexity of the fault (simple electrical fix vs. replacing motor or ducting)
- Whether the fan complies with current Building Regulations or needs an upgrade
- Additional repair work (e.g. replacing damaged ducting)
- Geographic location (labour rates may be higher in London and the South East)
- Urgency or out-of-hours work
⏱ How long does it take?
- Simple fault or motor replacement: 1–2 hours
- Complex repair (including ducting or rewiring): 2–4 hours
- Full fan replacement: Usually 2–3 hours depending on installation complexity
These times assume standard domestic extract fans without alterations to the building fabric.
🏠 Can you DIY it?
While it’s tempting to fix a faulty extractor fan yourself, there are several reasons to hire a professional electrician:
- Electrical safety risks: Fans involve wiring that must comply with Part P of the Building Regulations.
- Access and installation skills: Electricians ensure wiring is safe and correctly earthed.
- Certification: Professional work provides peace of mind and may be needed for insurance.
- Avoid voiding warranties or causing damage to wiring or ventilation.
If you’re confident with electrical work, the aesthetics of your home, and have the right tools and knowledge of UK safety standards, minor maintenance like cleaning the fan grille can be done yourself. Otherwise, call a qualified electrician.
💰 Typical UK price range
Expect to pay approximately £120 to £250 including VAT for extractor fan repairs or minor replacements in a domestic property. Larger, more complex jobs or installations in difficult locations could be more costly. Always get a detailed quote before proceeding.
✅ Handy tips before you start
- Make sure the electrician is qualified and Part P registered (check online or ask for proof).
- Clear access to the fan and surrounding area for the visit.
- Ask if the quote includes full safety testing and certification if appropriate.
- Keep all receipts, certificates, and paperwork safe in case your insurer requires evidence.
- After repair, clean the fan grille regularly and avoid blocking air vents.
- Consider periodic servicing for optimal performance, especially in high-humidity rooms.
- If replacing the fan, check that it’s suitable for the room size and complies with Building Regulations on ventilation.
Proper maintenance and professional repair will keep your extractor fan working efficiently, safeguarding your home from damp and poor air quality.
