What changes the installation cost?
- Replacing an existing fan or creating a new opening
- Length and route of the ducting
- Timer, pull cord or humidity sensing controls
- Access above ceilings or through external walls
- Need for a local isolator or new electrical supply
- Bathroom electrical zones and required fan rating
Replacement versus new installation
A like for like replacement is normally the lowest cost because the wiring, opening and duct route already exist. A new bathroom fan may need cable routing, switching, core drilling and external grilles. We check the room, airflow requirement and existing electrical protection before confirming the price.
Guide prices are not a substitute for a written quote. They assume normal access and a suitable existing electrical installation.
