Why Install an Extractor Fan?

Bathrooms tend to be the most humid areas in a home, with moisture from showers and baths accumulating and condensing on surfaces, which can result in persistent dampness and damage.

Without adequate ventilation, a bathroom may remain damp, leading to issues like mould, mildew, and structural damage over time. An extractor fan helps by drawing out excess moisture and expelling it outside, reducing the risk of these problems.

Installation Overview:

Extractor fans can be installed in several ways: through the ceiling with ducting extending to an external wall vent, directly through a wall to an exterior vent, or, less frequently, integrated into a window.

Since bathrooms are high-risk areas due to humidity, it's crucial to hire a certified electrician to perform the installation. You may need to handle the decoration and finishing touches yourself after the installation is complete.

The average expense for hiring an electrician, including labour and materials, can range from £150-£300. This depends on factors like the type of fan, ease of access, and overall complexity of the job.

Estimated Lifespan of Extractor Fans:

According to Pristine Property Group, "Most decent bathroom extractor fans need changing every 8-10 years."

Supply Costs:

If you plan to handle the installation yourself, you only need to budget for supplies and materials. The price of a new extractor fan can vary depending on its type and quality, typically starting at £20 and reaching up to £100.

Additional Costs:

The installation of an extractor fan could be part of a larger bathroom renovation, which might cost between £5,000-£8,000 depending on the specifics like size and materials. If a full remodel isn’t within budget, there are still other related tasks to consider, such as re-tiling or re-grouting, which can range up to £700 and £250-£300, respectively.

Labour Costs and Job Duration:

Electricians typically charge around £60 per hour for basic installations, which usually take 1-2 hours. Larger, more complex projects may involve costs up to £300 for a full day’s work. In most cases, a single electrician handles these tasks, though bigger projects may require assistance.

Cost Influencing Factors:

Several factors can impact the total cost of installation, such as:

• Type of Fan: Prices vary by fan type, with standard wall fans starting from £30 and ceiling fans priced around £40. Higher-quality fans, offering more durability, come at higher prices but may save on future repair costs.
• Fan Size: Larger fans that use more power can be more expensive and louder. A basic fan for a smaller bathroom typically costs between £30-£35.
• Access: Installing ceiling fans or hard-to-reach window fans may require loft access or scaffolding, potentially adding time and costs. A scaffolding tower can cost £250 plus a day’s labour.
• Additional Jobs: Extras such as installing an on/off switch or integrating a pull cord, auto system, or light-activated switch could also raise the final price.

Installation Process:

When discussing installation with your electrician, it's essential to know what’s involved:

1. Preparation: The electrician will assess the space, mark the installation points, and ensure the electrics are safely turned off.
2. Vent Fitting: After cutting and clearing space, they’ll secure fittings and duct pipes.
3. Fan Installation: The fan's frame is secured, and ducting is attached between the fan and vent.
4. Electrical Setup: The electrician will connect the electrical components, fit the grill cover, and ensure everything is operational.

DIY Installation:

If you’re replacing an existing fan and using the same wiring and venting, this can be a manageable DIY task. However, always inspect the current setup to ensure it’s in good condition. If you’re undertaking a full installation, hiring an electrician is recommended due to the complexity of electrical work and the need for compliance with regulations.

Building Regulations and Permissions:

Before making any permanent alterations to your home’s power circuits, check with your local Building Control Department to ensure all work complies with building codes. Replacement work or new installations should meet the latest IEE Wiring Regulations and have RCD protection.

Choosing the Right Fan

When selecting a bathroom fan, consider different options:

• Wall Fans: Affordable and easy to install, but they may collect dust and can be noisier.
• Ceiling Fans: Quiet and discreet but can be harder to reach and install.
• Window Fans: Effective at removing steam but more complex to install and may obstruct the view.
• Axial Fans: Common and cost-effective but may need more frequent repairs.
• Centrifugal Fans: Less common, suitable for longer duct runs.
