Electrical panel upgrades are one of the most common projects we complete for Houston-area homeowners — and one of the most misunderstood when it comes to cost. The honest answer is: it depends. But we can give you a clear framework for understanding what you’re likely to pay and what drives the price.
Typical Cost Range for a Panel Upgrade in Houston
Most residential electrical panel upgrades in the Houston area fall in the range of $1,500 to $4,000, with the average project landing around $2,000–$2,500. However, several factors can push the cost higher or allow for savings.
What Drives the Cost of a Panel Upgrade?
Panel Size (Amperage)
The most significant cost factor is the size of the panel you need:
- 100-amp panel: Sufficient for smaller homes with modest electrical needs. Less common in new upgrades.
- 150-amp panel: A middle-ground option for mid-size homes.
- 200-amp panel: The standard for most Houston homes today. Handles modern electrical loads including central AC, EV chargers, and multiple large appliances.
- 400-amp panel: Required for very large homes or those with significant electrical demands (whole-home generators, EV charging infrastructure, etc.).
Upgrading from a 100-amp to a 200-amp panel is the most common project and falls squarely in the $1,800–$3,000 range for most Houston homes.
Condition of Existing Wiring
If your home’s wiring is in good condition, a panel swap is relatively straightforward. If the inspector finds knob-and-tube wiring, aluminum branch circuit wiring, or significant deterioration, additional work will be needed — and costs will increase accordingly.
Permit and Inspection Requirements
In Houston and surrounding municipalities, electrical panel upgrades require a permit and inspection. This is not optional, and any reputable electrician will pull the permit as part of the job. Permit costs vary by jurisdiction but are typically $75–$200 and are included in most contractor quotes.
Utility Coordination
CenterPoint Energy (Houston’s utility provider) may need to disconnect power at the meter while the panel is replaced. Coordinating this adds time to the job but is standard practice.
Panel Brand and Quality
Not all panels are equal. We use and recommend Square D, Siemens, and Eaton panels — brands with strong reliability records. Avoid contractors offering deeply discounted panels from off-brand manufacturers.
What About Older Panels That Need to Be Replaced?
If your home still has a Zinsco or Federal Pacific (Stab-Lok) panel, replacement isn’t optional — it’s a safety issue. These panels are known to fail to trip in fault conditions, creating a serious fire risk. Insurance companies in the Houston area increasingly refuse to cover homes with these panels. The cost to replace them is the same as a standard upgrade.
Is a Panel Upgrade Worth It?
Almost always yes — especially if you’re planning to:
- Install an EV charger
- Add a whole-home generator
- Remodel your kitchen or add a room
- Install central AC in a home that previously didn’t have it
- Add solar panels
An upgraded panel also increases home value and may lower your homeowner’s insurance premium.
Can an Old Panel Affect My Home Insurance?
Yes. Many Houston-area insurance carriers will increase premiums or decline coverage for homes with panels over 30 years old, undersized panels (under 100 amps), or known problem brands. If you’re buying or selling a home, a panel upgrade may be a lender or insurer requirement.
