Planning ranges, not quotes. A real price needs a site visit to look at your panel, gas meter and where the unit will sit.

Where the Money Goes
| Line item | Published range (HomeGuide) |
|---|---|
| Generator unit | $3,000–$6,000 |
| Labor | $3,000–$5,000 |
| Automatic transfer switch | $600–$2,500 |
| Electrical wiring | $6–$8 per foot |
| Gas line | $12–$25 per foot |
| Concrete or composite pad | $150–$400 |
| Permits | $80–$450 |
Worked Example
ESTIMATE A unit set 15 feet from the panel and 20 feet from the gas meter adds about 15 × $6–$8 = $90–$120 of wiring and 20 × $12–$25 = $240–$500 of gas line on HomeGuide’s per-foot rates. Our multiplication only. Put the unit across the yard and those numbers grow quickly, which is one reason installers prefer a spot near both meters.
Costs People Forget
- Gas meter upgrade. If the existing meter cannot supply the generator plus your furnace and water heater, the gas utility may need to change it.
- Panel upgrade. Older or full panels sometimes need replacing first.
- Propane tank if you have no gas service: $400–$1,800 (HomeGuide).
- Cold-weather kit for battery and oil heating: $130–$500 (HomeGuide).
- Maintenance: $200–$650 per year (HomeGuide).
Compare Quotes Line by Line
| Ask | Why |
|---|---|
| Brand, model and kW rating? | Prices only compare at the same size. |
| Which transfer switch, and is load management included? | This changes both price and what runs. |
| Who handles gas piping, and is the gas meter checked? | Gas work needs the right license and enough supply. |
| Are permits, pad and startup included? | Low quotes sometimes leave these out. |
| What are the warranty terms and who services it? | Registration and service records often matter. |
Checking Licenses
Ask for the electrical license number and look it up through the Oklahoma Construction Industries Board. Broken Arrow also requires electrical contractors to register with the city (City of Broken Arrow permitting and licensing).
Frequently Asked Questions
Is $6,000 to $11,000 realistic in Broken Arrow?
That is the range on both homeyou’s Broken Arrow page and HomeGuide’s national guide. Big units, long runs and panel upgrades push it higher.
What makes one quote much higher than another?
Usually the generator size, the type of transfer switch, gas line length and any panel or meter upgrade. Compare those line by line.
Are maintenance plans worth it?
HomeGuide puts maintenance at $200–$650 a year. A plan makes sense if it includes battery checks and a simulated outage test.
