Whole-House Surge Protector Installation
A whole-house surge protector mounts at or next to your electrical panel and limits voltage spikes coming into the home. Installation averages about $500, with most homeowners paying $200–$800, according to HomeAdvisor.

|---|---|
| Installed | $200–$800 (about $500 average) |
| Device only | $60–$500 |
| Electrician labor | Often $150–$200 (minimum service fee is common) |

What it does and does not do
- It helps protect against surges coming in from the utility lines, such as from grid switching.
- It does not protect against a direct lightning strike.
- Many surges start inside the home (motors, compressors); plug-in surge protectors at sensitive electronics add a second layer.
Recent editions of the National Electrical Code (2020 and later) require surge protection when a home's electrical service is installed or replaced. Where your area has adopted those editions, your electrician may include it with a panel upgrade.
Who should install it
Installation involves working inside the panel. Hire a licensed electrician, and ask whether a permit is required where you live. It is often cost-effective to add one while an electrician is already doing other panel work (panel replacement cost).
