Electrical Panel Upgrade Cost in Texas: A Homeowner Guide

In Texas, most homeowners spend roughly $1,500 to $4,000 to upgrade an electrical panel, with straightforward 100-amp jobs often landing near the lower end and 200-amp upgrades commonly running $2,500 to $4,500+. Your real number depends on the amperage, the condition of your meter and wiring, permit and inspection fees, and how easy the panel is to reach. Because those factors swing the price so much, the only way to know your true cost is to get a few quotes from local licensed electricians and compare them.

100A vs. 200A: typical price ranges

Amperage is the biggest single driver. As a general guide for Texas homes:

• 100-amp panel: often about $1,200–$2,500. Fine for smaller or older homes with modest electrical loads.
• 200-amp panel: commonly $2,500–$4,500+. The most popular choice today, and usually needed if you're adding an EV charger, a bigger HVAC system, or a major addition.
• Panel relocation or a full service upgrade (new meter base, riser, and grounding) can push costs higher still.

These are ballpark ranges, not quotes. Costs vary by the scope of work, your specific home, and your region of Texas, so treat any single figure with caution.

What drives the cost

• Amperage and panel size: higher capacity and more breaker slots cost more in both parts and labor.
• Meter and service entrance: if the meter base, weatherhead, or service cable also need replacing, that adds materials and coordination with your utility.
• Permits and inspection: most Texas jurisdictions require a permit and a passed inspection, and the utility must disconnect and reconnect power. Fees vary widely by city and county.
• Wiring condition: older homes with aluminum branch wiring, missing grounding, or code issues may need extra work to bring the system up to current code.
• Location and access: a panel that's hard to reach, needs to be moved, or requires new interior drywall repair raises labor time.
• Backup and add-ons: whole-home surge protection, a generator interlock, or a subpanel are common upgrades that add to the total.

Signs you may need a panel upgrade

Watch for these common warning signs:

• Breakers that trip often, or a fuse box instead of breakers.
• Flickering or dimming lights when large appliances kick on.
• A warm panel, buzzing, scorch marks, or a burning smell — treat these as urgent and call a licensed electrician.
• Relying on power strips and extension cords because you're short on outlets or circuits.
• Adding major loads: an EV charger, a new AC or heat pump, a pool, a hot tub, or a room addition.
• An older or recalled panel brand, or a home that still has its original panel from decades ago.

Texas homes lean hard on air conditioning through long, hot summers, and more households are adding EV chargers — both push existing panels toward their limits. If your panel is undersized or aging, an upgrade improves safety and gives you headroom for future needs.

Permits and inspection

An electrical panel upgrade is not a DIY project in Texas — it involves the service entrance, grounding, and a utility disconnect. Reputable electricians will pull the required permit, schedule the inspection, and coordinate with your power company to shut off and restore service. When you compare quotes, confirm the permit and inspection are included so you're comparing apples to apples. Skipping permits can create safety hazards and problems when you sell your home.

How to get an accurate price

The fastest way to a real number is to have a few local pros look at your actual panel and home. Here's how to keep it simple:

1. Describe your goal clearly — for example, "upgrade to 200A to add an EV charger."
2. Get at least two or three written quotes so you can compare scope, not just price.
3. Ask each pro to confirm their Texas electrical license and current insurance, and verify it yourself before hiring.
4. Check that permits, inspection, and any drywall or cleanup are in writing.
5. Be cautious of a bid far below the others — it may skip permits or use lower-grade equipment.

Frequently asked questions

Is a 200-amp panel worth it over 100-amp?

For most Texas homes today, yes. A 200-amp service gives you room for central AC, an EV charger, and future additions, and the cost difference is often modest compared with upgrading again later.

How long does a panel upgrade take?

Many straightforward upgrades are completed in a single day, though your power will be off for part of it and inspection scheduling can add time. Larger jobs with meter or wiring work take longer.

Does homeowners insurance care about my panel?

It can. Some insurers ask about older or recalled panel types. Upgrading an outdated panel may help with coverage and generally improves home safety — check with your own insurer for specifics.
