Extras that add to the bill
Angi puts an electrician at $100 to $150 for a simple switch install and warns that cutting into a wall can add $50 to $75 per square foot of drywall repair, or $150 or more in total.2 HomeGuide notes most electricians charge a $75 to $125 service call fee with a one-hour minimum, so bundling several switches in one visit lowers the per-switch cost.3 HomeGuide also says to confirm your wiring before buying a dimmer or smart switch, since many need a neutral wire.3
DIY or hire
Swapping a switch is one of the simpler electrical jobs if you shut off the breaker and match the existing wiring, but any new wiring, moved boxes or transfer switches belong to a licensed electrician. Home Depot’s dimmers category lists the main styles.
