What Impacts the Cost of Bathroom Fan Installation?
Several factors will affect the amount you pay for bathroom fan installation in Ireland.
- Type of fan: Standard, centrifugal, and inline fans all have different base costs and installation requirements.
- Complexity: Installing into an existing hole and wiring is cheaper than creating a new duct run and new electrics.
- Property location: Installers in Dublin and other cities may charge a premium compared to rural areas.
- Additional repairs: Ceiling or wall repairs after installation can increase costs.
- VAT: Always confirm if prices quoted include the standard 23% VAT.
Types of Bathroom Fans and What They Cost
The fan’s design and power affect both the purchase price and installation cost. Here’s what you can expect in Ireland for 2026:
- Standard 100mm Extractor: Most common, typically €150 supplied and installed.
- Centrifugal Fan: Handles longer ducting, around €190 installed.
- Inline Fan: Usually required for ceiling or attic extraction, and starts from €350 supplied and fitted.
Replacement vs. New Installation: What to Expect
Replacing an older fan with a similar model is straightforward, so it’s the cheapest option. The job usually takes about an hour and doesn’t need disruptive works. In contrast, installing a fan where there’s none means more labour and often cutting new vents through walls or ceilings, running new power cables, and sometimes repairing surfaces afterwards—hence the higher cost.
VAT, Grants and Regulatory Matters
Contractors often advertise prices that either include or exclude VAT (23%). Always double-check what’s included in any price you’re quoted, as VAT can make a noticeable difference to your total.
As of 2026, the Sustainable Energy Authority of Ireland (SEAI) does not offer a specific grant for bathroom fan installation, but if you’re planning a broader home energy upgrade, check SEAI’s website or call them to see if ventilation improvements qualify for support under a more comprehensive scheme.
Getting the Best Value: Practical Tips
- Get several quotes and compare not just price but experience and reviews.
- Always use a certified electrician or bathroom specialist for both safety and compliance.
- Choose a fan appropriate for your bathroom’s size (check extraction rate, usually in cubic metres per hour).
- Consider energy efficiency—more efficient fans may cost more up front but save on running costs.
- Ask if extra charges may apply (e.g. repairing ceilings, longer duct runs, or electrical upgrades).
