How Much Should Subpanel Installation Cost?
Fair price range (2026)
Depends on scope, materials, and local labor rates.

Why quotes vary
- • Run length and access: fishing wire through finished walls costs far more than open basement runs
- • Panel capacity: if your panel is full, legitimate tandem breakers or a subpanel may be needed — a full upgrade often isn't
- • Home age: knob-and-tube or aluminum wiring adds real cost and care
- • Permits: panel work requires a permit and utility coordination — that's real, but should be itemized, not vague
- • Flat-rate vs hourly: both are fine, but never both on the same line items
