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."
Breakdown of Costs:
Below is an estimate of material and labour expenses when hiring an electrician to install or replace a bathroom extractor fan:
| Job Description | Duration | Material Cost | Labour Cost |
|---|---|---|---|
| Replace an existing | 1 hour | £60 | £25 |
| Install a new (with ducting to an external wall) | 6 hours | £90 | £60 |
| Install new fan (with ducting through eaves) | 1-2 days | £90 | £200 |
| Install shower fan (with ducting to an external wall) | 6 hours | £70 | £80 |
| Install window fan | 1 day | £70 | £160 |
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.
| Fan Type | Cost Range |
|---|---|
| Wall | £20-£50 |
| Ceiling | £30-£55 |
| Window | £45-£70 |
| Axial | £25-£90 |
| Centrifugal | £50-£100 |
| Inline | £40-£110 |
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:
- Preparation: The electrician will assess the space, mark the installation points, and ensure the electrics are safely turned off.
- Vent Fitting: After cutting and clearing space, they’ll secure fittings and duct pipes.
- Fan Installation: The fan's frame is secured, and ducting is attached between the fan and vent.
- 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.
FAQ's
What is the typical cost for installing a bathroom extractor fan?
The price to install an extractor fan varies but typically averages around £300. This cost can change based on factors such as the type of fan chosen, the complexity of installation, and any additional labour or materials needed.
What factors can influence the installation cost of a bathroom fan?
The main aspects that can impact installation costs include the type and quality of the fan, the location within the bathroom, and whether extra work such as ducting through walls or roofs is required. Accessibility can also play a role, with installations requiring scaffolding or specialised access adding to the total expense.
How long does it usually take to install a bathroom extractor fan?
A standard replacement job might take an experienced electrician about an hour. However, installing a new fan with added ducting or complex wiring could extend the job to anywhere from six hours to one or two days, depending on the specific requirements.
Can I install an extractor fan myself?
While swapping out an old fan for a new one using the same wiring and ducting is a manageable DIY task for some, a full installation involving new wiring, cutting into walls or ceilings, and connecting to external venting is more complex. It’s advisable to hire a professional electrician for this type of job to ensure compliance with safety standards and building regulations.
Are there additional costs to consider when installing a bathroom extractor fan?
Yes, in addition to the fan installation itself, you may need to budget for related work such as installing a new switch, re-tiling or patching walls, or updating any wiring. Decorative work post-installation, such as repainting or re-plastering, could also add to your expenses.
Do I need to follow building regulations when installing a bathroom extractor fan?
Absolutely. Any electrical work done in a bathroom must meet building and safety standards. This might involve notifying local building control or having a qualified electrician carry out or sign off on the work to ensure it adheres to regulations.
What should I consider when choosing an extractor fan?
When selecting an extractor fan, consider factors like the size of your bathroom, the fan’s power and noise level, and its efficiency. Options range from cost-effective wall fans to more durable ceiling or window fans. Your choice will affect both installation complexity and cost.
