Estimate generator transfer switch installation cost — with the free electrical calculator.
A transfer switch lets a generator power your panel safely — no extension cords, no backfeeding the grid. Here's the real 2026 cost.
THE SHORT ANSWER
The short answer
Manual transfer switches run $400–$1,500 installed in 2026 (switch $200–$800). Automatic whole-house switches run $3,000–$3,500 installed. Kits for portable generators run $300–$500. Electrician labor is the biggest variable.
What it costs
A manual transfer switch runs $400–$1,500 installed. The switch itself runs $200–$800. An automatic or service-rated whole-house switch runs $3,000–$3,500 installed. Portable generator kits run $300–$500. Permits add $100–$300.
- Manual installed: $400–$1,500
- Switch alone: $200–$800
- Automatic: $3,000–$3,500
- Portable kit: $300–$500
Manual vs automatic
Manual switches need you to flip a few breakers when the power dies — cheap and reliable. Automatic switches sense the outage and start the generator themselves — $3,000+ but hands-free. Portable generators pair with manual; standby generators use automatic.
