How Much Does It Cost to Upgrade a 100-Amp Panel to 200-Amp?
Pricing factors and what the work actually involves.
By Electric · · 4 min read
A 100-amp service panel is fine if your house was built in the 1980s or earlier and you run minimal electric load. But if you've added a second air conditioner, a hot tub, an electric vehicle charger, or just accumulated more appliances over time, you'll hit the ceiling fast. When you're constantly tripping breakers or noticing dimmed lights when the AC kicks on, it's time to think about upgrading to 200 amps. The cost usually lands between $3,000 and $6,000 for the whole job, though it can run higher depending on what your setup looks like and what the local utility company requires.
What Actually Changes When You Upgrade
The panel itself is only part of the picture. A 200-amp upgrade means replacing your main service entrance, which includes the meter, the main breaker, the panel box, and sometimes the wiring from the utility pole to your house. The utility company has to come out and pull new service lines, which you can't do yourself and which they'll often charge for separately. Inside your house, the electrician has to run new wire from the meter to the panel and potentially upgrade the breaker slots to handle higher amperage. If your house has aluminum wiring already in place, that doesn't automatically need replacement, but the electrician will inspect it and flag any corrosion issues that could cause problems.
Labor, Materials, and Permitting
Labor typically runs $1,500 to $2,500 for a competent electrician to handle the installation, assuming straightforward access to the panel and meter. Materials for the panel, breakers, wire, and disconnects can be $1,000 to $2,000 depending on the brand and your specific setup. Then there's the utility company's fee, which in many parts of Texas ranges from $500 to $1,500 just to install the new meter and service lines. You also need an electrical permit from your city or county, usually $100 to $300, and that permit requires an inspection before and after the work. Don't skip the permit. An unpermitted panel upgrade can create liability issues when you sell your house and can void your homeowner's insurance if there's ever a fire.
Factors That Push the Price Higher
If your main panel is in an awkward location, buried behind cabinets or in a tight crawl space, the electrician will spend more time and charge more labor. If the utility company has to run new service lines a long distance or work around obstacles, their fee climbs. If your current meter is on the opposite side of the house from where the new panel needs to go, that's more wire and more labor. Some older homes have a separate disconnect switch between the meter and the panel, and that may need to be relocated or upgraded as part of the job. If you've got a sub-panel or multiple disconnects feeding different parts of your house, the scope gets bigger. Grounding and bonding requirements also vary by location, and if your existing ground rod or grounding conductor is compromised, that adds cost to fix properly.
What You Can Expect Timeline-Wise
The actual installation usually takes one full day, sometimes two if there are complications or if the utility company is slow to coordinate. The utility company's side of things can take longer. They might schedule the meter pull-out and install weeks in advance, and you'll need to be home for that appointment. The whole process from your first call to having a fully operational 200-amp panel typically takes two to four weeks, depending on permit processing and utility scheduling in your area.
Should You Upgrade Now or Wait
If you're regularly hitting breaker limits or you're planning a major renovation that will add significant electrical load, upgrade now. Waiting doesn't save you money because the work doesn't get cheaper, and you risk damage to appliances or a house fire from an overloaded system. If your panel is stable and you're not adding major loads, you can wait. But if you're thinking about an EV charger, a new HVAC system, or a pool, plan the panel upgrade as part of that project. It's always cheaper to do it all at once than to pay for two separate utility company visits and two separate permits.
