Electrical Panel Upgrade Cost in Texas: 2026 Pricing Guide

Panel upgrades are one of the most common and most profitable jobs for Texas electrical contractors. With the state's aging housing stock (particularly in older neighborhoods of Houston, Dallas, and San Antonio), growing EV adoption, and increasing home electrical loads from solar installations and smart home systems, demand for panel upgrades continues to climb.

This guide covers real-world pricing for panel upgrades across major Texas markets in 2026.

100A to 200A panel upgrade

This is the bread-and-butter residential panel upgrade. Most Texas homes built before 2000 have 100-amp or 150-amp service, which is insufficient for modern electrical loads. A 200-amp upgrade is the standard recommendation for most single-family homes.

Typical cost range: $2,500 to $4,800

This price includes the new 200-amp panel and breakers, replacement of the meter base (usually required by the utility), service entrance cable, weatherhead, grounding electrode system, permitting, and labor. In the DFW metroplex, average pricing sits around $3,200 to $3,800. Houston tends to run slightly lower at $2,800 to $3,500 due to higher contractor density and competition. Austin, with its higher cost of living and tighter permit timelines, averages $3,500 to $4,500.

200A to 400A panel upgrade

Larger homes, homes with solar installations, EV chargers, pools, and workshops may need 400-amp service. This is a more complex job that requires utility coordination, larger conduit, and often a CT (current transformer) metering setup.

Typical cost range: $5,500 to $12,000

The wide range reflects the significant variation in scope. A straightforward 400-amp upgrade in a newer home with accessible electrical infrastructure might come in at the low end. An older home requiring a new utility service drop, ditch work for underground service, and extensive rewiring of the existing distribution system will be at the higher end. Always perform a thorough site assessment before quoting 400-amp work.

Sub-panel installation

Adding a sub-panel is a common alternative when the main panel is at capacity but the service size is adequate. This is typical for garage workshops, home additions, or detached structures.

Typical cost range: $1,200 to $3,000

Pricing depends on the sub-panel size, distance from the main panel, and whether new conduit runs are needed. A 60-amp sub-panel in an attached garage is a quick job. A 100-amp sub-panel feeding a detached workshop 80 feet from the main panel is significantly more work.

Cost factors that affect pricing

Utility requirements. Texas has multiple utility providers (Oncor, CenterPoint, AEP, TNMP), and each has different requirements for meter base specifications, service entrance configurations, and inspection processes. Oncor in DFW, for example, has specific meter base models they will accept. CenterPoint in Houston has different requirements. Factor utility-specific requirements into your estimates.

Permit costs. Permit fees vary by municipality. Dallas charges approximately $75 to $150 for a residential electrical permit. Houston runs $80 to $200. Smaller cities and unincorporated areas may be less. Always include permit costs as a line item so the customer sees what they are paying for.

NEC code compliance. Current NEC requirements (AFCI breakers, surge protection, emergency disconnect) add $500 to $1,500 to the material cost of any panel upgrade compared to pre-2020 code requirements. These are not optional. Make sure your estimates reflect current code and explain the requirements to the customer.

Drywall and finish work. If the panel is in a finished space (basement, garage wall), you may need to patch drywall or coordinate with a drywall contractor. Some electricians include basic patching in their price. Others exclude it and let the homeowner handle it separately. Be clear about what your estimate includes.

How to price panel upgrades profitably

The most successful Texas panel upgrade contractors follow a consistent pricing methodology. They know their material costs cold (including local supplier pricing for the specific panel brands they use), they track their actual labor hours per job type, and they apply a consistent markup that covers overhead and profit.

For a typical 200A upgrade, a profitable breakdown looks something like this: materials at $800 to $1,200, labor at 6 to 10 hours (depending on complexity), permit at $75 to $200, and a markup of 30% to 50% depending on your overhead structure and market conditions. Do not race to the bottom on pricing. A clean, professional, code-compliant panel upgrade is worth a premium over the cheapest bid.

Using a tool that lets you generate consistent, accurate estimates quickly (rather than rebuilding the estimate from scratch each time) is critical for maintaining margins across a high volume of panel upgrade jobs.
