Electrical Panel Upgrade Cost in Texas: 2026 Bids, TDU Rules, and What Freeze Prep Adds

Electrical panel upgrade cost in Texas for 2026: real 200 amp pricing, how Oncor and CenterPoint control your timeline, permits, freeze prep, and comparing bids.

Electrical Panel Upgrade Cost in Texas: 2026 Bids, TDU Rules, and What Freeze Prep Adds

A straight 200 amp panel swap in Texas runs about $2,300 to $5,000 in 2026. Once the meter can, the riser, and the overhead service drop come into the scope, most homeowners land between $3,900 and $8,800. Austin and the close-in Dallas suburbs price at the top of those bands, while Lubbock, Abilene, and the Rio Grande Valley usually come in a quarter cheaper.

What makes Texas different from almost every other state is that two separate companies touch your electricity. The retail provider you picked off a comparison site does not own a single wire on your street. The poles, the transformer, and the meter belong to a transmission and distribution utility, and that company decides when your power gets pulled and reconnected.

Homeowners get tripped up by this constantly. They call their retail plan's customer service line about a panel replacement and get a representative who has no ability to schedule anything, because the work order has to go to Oncor, CenterPoint, AEP Texas, or Texas New Mexico Power instead.

What a Texas Electrician Is Pricing When They Quote You

The base job is a new load center sized to a load calculation, breakers for every existing circuit, two ground rods, bonding at the water line and the gas line, a typed circuit directory, the permit fee, and the inspection. Moving thirty circuits into a new enclosure one at a time takes a competent two person crew most of a day.

Arc fault and ground fault breakers are where quotes diverge the most. Texas adopts the National Electrical Code at the state level for one and two family dwellings, and the current edition demands protection on far more circuits than a 1990s panel carries. Twenty five protected breakers instead of twenty five standard ones can move a bid $800 to $1,600 all by itself.

The second big variable is whether the electrician is replacing only the panel or the whole service. A panel change reuses your existing meter can, mast, and service conductors. A service change replaces all of it, and in Texas that automatically pulls the TDU into the schedule.

Overhead Service Versus Underground

Most Texas homes built before the mid 1980s have an overhead drop coming to a mast on the roof or a bracket on the gable end. Those are the cheaper of the two to work on because everything the electrician needs is reachable from a ladder.

Underground service, standard in tract neighborhoods built since the late 1990s across Collin, Denton, Fort Bend, and Williamson counties, is a different animal. If the conductors between the transformer pedestal and the house have to be replaced, you are paying for trenching across a lawn and a sprinkler system, and that adds $1,500 to $4,500.

Slab Homes and Where the Panel Lives

Texas builds on slab almost everywhere, which means no basement and no crawl space, and the panel usually sits in the garage or on an exterior wall behind the meter. That is the least expensive layout an electrician can work with, since the meter and the load center are back to back.

Panels tucked into hallway closets or utility rooms in older Houston and San Antonio homes cost more to replace. Code requires a defined working clearance in front of the enclosure, and when the existing spot cannot deliver it, the panel moves. Relocating a panel adds roughly $900 to $2,600 depending on how far the feeders have to travel.

Oncor, CenterPoint, and Who Controls Your Calendar

Your TDU is assigned by geography, not by choice. Oncor covers most of North and West Texas including Dallas, Fort Worth, Waco, and Midland, and CenterPoint handles the Houston area.

AEP Texas runs the coastal bend and much of South Texas. TNMP serves pockets around Katy, League City, and the Panhandle.

Municipal utilities and cooperatives operate under their own rules and are not part of the deregulated market at all. Austin Energy, CPS Energy in San Antonio, Brownsville PUB, and rural co-ops like Pedernales and Bluebonnet both deliver and sell the power, which simplifies the phone calls but not always the timeline.

For a panel only swap, the TDU sends a technician to pull the meter, the electrician does the work, the city inspects, and the TDU comes back to reset. Two visits, and the gap between them is what determines whether you are without power for four hours or two days.

For a full service change, the sequence adds a permit release step. The inspector's approval has to reach the utility electronically before a reconnect gets scheduled, and in busy months around Dallas and Houston that handoff has been taking three to five business days.

Getting the Timing Right in Summer

Nobody wants to spend a July night in Houston without air conditioning. Ask the electrician to confirm the meter pull window in writing, and ask specifically whether they have ever had a job go overnight with that TDU.

Good crews in Texas book panel work for early morning starts between June and September for exactly this reason. Attic and garage temperatures above 110 degrees also slow the work down, which is one quiet reason spring and fall bids sometimes come back lower.

The Loads Filling Up Texas Panels

The February 2021 freeze changed how a lot of Texans think about their electrical service. Households that rode out days without heat added standby generators, transfer switches, and in growing numbers, home batteries, and every one of those needs panel capacity and space.

Electric vehicle charging is the other driver. A Level 2 charger pulls a dedicated 40 or 60 amp circuit, and a 1985 house in Richardson with 100 amp service, a five ton air conditioner, an electric range, and a dryer has nothing left to give it.

Backyard buildout does the same thing quietly. A pool with a variable speed pump and a heater, an outdoor kitchen, a workshop with a welder, and a casita in the back all pull from the same service, and the total shows up in the load calculation whether the homeowner thought about it or not.

When the Numbers Say You Can Skip the Upgrade

A load calculation done under Article 220 sometimes shows that an existing 100 amp or 150 amp service has more headroom than the homeowner assumed. Gas heat, a gas water heater, and a gas range together leave a surprising amount of room, and gas is common across most Texas metros.

Load management hardware is the other path. Devices that let a charger and a dryer share capacity, or that shed the charger when the air conditioner starts, run $600 to $1,700 installed and can defer a service upgrade for years. Ask any electrician who quotes a full service change whether they ran the calculation first, and ask to see it.

Licensing, Permits, and Comparing Bids Without Guessing

Texas licenses electricians through the Department of Licensing and Regulation, and every license number is searchable in the state's public database. A master electrician holds the license the company operates under, and the business itself needs a separate electrical contractor license.

Verify both before you sign anything. It takes about ninety seconds, and it filters out the storm chasers who show up after every big weather event with a truck and a magnetic sign.

Permits are handled city by city, which matters more in Texas than in states with county wide building departments. Houston, Dallas, Austin, Fort Worth, and San Antonio each run their own process, and homes in unincorporated county areas may have no municipal permit requirement at all while the TDU still demands an inspection before reconnecting.

The best way to compare three bids is to make them describe the same job. Ask each one for the panel brand and amperage, the number of arc fault and ground fault breakers, whether the meter can and riser are included, whether a service upgrade request has been filed with the TDU, the permit fee, and how many hours the power will be off. You can read written scopes from licensed electricians across Texas side by side once they are all answering the same questions, and our Texas home services cost guides walk through the trades that tend to follow this one.

Two other line items are worth asking about. A generator interlock kit costs far less installed during a panel replacement than as a separate visit later, and surge protection at the panel runs $250 to $500 when the cover is already off.

Frequently Asked Questions

How long will my power be off during a Texas panel upgrade?

Plan on six to nine hours for a panel only replacement where the TDU pulls and resets the meter the same day. A full service change that requires an inspection between the pull and the reset can leave you without power overnight, so ask which one you are buying before the crew arrives.

Do I need a permit to replace an electrical panel in Texas?

Inside city limits, yes, in every major Texas municipality. In unincorporated areas the answer varies, but Oncor and CenterPoint both require documentation of an approved inspection before they will reconnect a changed service, so the paperwork rarely disappears entirely.

Is 200 amp service enough for a house with an EV and a pool?

For most Texas homes, yes. A 3,000 square foot house with a heat pump, a pool pump, and one Level 2 charger typically calculates out under 160 amps. Two chargers plus an electric range and an electric water heater is where 400 amp service starts getting discussed.

Why is my neighbor's panel quote so much lower than mine?

Nine times out of ten it is scope. Their bid was a panel swap reusing the meter can and existing conductors, and yours includes a new meter base, a new mast, and a TDU service upgrade request. Compare the line items, not the totals.
