Generator Installation Cost
The biggest cost driver here isn’t labor, it’s which generator you’re installing: a portable-generator inlet box is a small job, a whole-home standby unit sized for central air and a well pump is a much bigger one, with everything in between sized to how much of the house you want covered during an outage.
| Low | High | Unit |
|---|---|---|
| $3000 | $15000 | per installation |
What moves the price
- Generator type: portable inlet box versus a permanent standby unit
- Generator size (kW), sized to which circuits you want to keep running during an outage
- Automatic transfer switch versus a manual one
- Site work: pad, clearances, and fuel-line hookup for a standby unit
- Permit and utility notification, required in most jurisdictions for a standby install
