What you're paying for
What is usually included: The switch or dimmer, the swap in an existing box, and 30–60 minutes of labor.
What moves the price:
- Smart dimmers ($40–$80) versus basic toggle switches ($3–$10)
- Three-way and four-way setups that take longer to trace and wire correctly
- Older boxes with no neutral wire, which many smart switches require
- Bundling several switches in one visit, which lowers the per-switch cost
Switch type (single-pole vs. dimmer, 3-way or smart), whether a neutral wire is present, and the service-call minimum.

Frequently asked
Is $200 a fair price for light switch or dimmer installation in Illinois?
Yes. $200 is right around what most homeowners in Illinois pay. Anything from $39 to $440 is inside the normal range for a licensed electrician; above $440 it is worth getting a second quote.
Why do quotes for the same job vary so much?
Smart dimmers ($40–$80) versus basic toggle switches ($3–$10). Three-way and four-way setups that take longer to trace and wire correctly. Company overhead matters too: a large company with trucks, dispatchers and a warranty department charges more than a one-person shop, and both can be honest prices.
When should I get a second quote?
Any time a quote lands above $440, or when the contractor cannot break it into parts, labor and fees. Ask for the itemized version, ask what would change the price, and confirm licensing and insurance. You can also paste the quote into the free QuoteJury checker for an instant second opinion.
