1. Amperage: 100 Amp vs 200 Amp
The single biggest cost driver is the service size you end up with. Many older Fort Worth homes were built with 100-amp service, and a like-for-like 100-amp swap is the lighter end of the work. A 200-amp upgrade is a bigger job: a larger panel, heavier service conductors, and more coordination with the utility.
The reason most homeowners still choose the 200-amp upgrade is headroom. If you might add a car charger, a generator, a new HVAC system, or a shop down the road, sizing up once is cheaper than paying for a second upgrade later. We run a load calculation to tell you which size your home actually needs.
2. Panel Location and Relocation
A panel in an accessible spot - an exterior wall or an open garage - is faster to work on than one buried in a finished closet. The cost climbs when the panel must be relocated, because that means new conductors to the new position, patching the old location, and sometimes reworking the service entrance. Moving the meter adds utility coordination on top.
3. Condition of the Service Entrance
The meter base, the weatherhead, and the grounding and bonding system all have to be sound and up to current code. On an older home, replacing the panel often surfaces a meter base or grounding setup that must be brought up to standard at the same time - not an upsell, but the work required to pass inspection.
4. Permits and Inspection
A panel replacement in Fort Worth is permitted work, and the permit and inspection are part of the cost of doing it correctly. Be cautious of any quote that is unusually low because it skips the permit; unpermitted electrical work can surface as a problem when you sell the home.
5. Oncor Coordination
Oncor owns the service drop and meter in the Fort Worth area, so replacing a panel - and especially upgrading the service size - means a disconnect and reconnect scheduled with the utility. It is one of the reasons a panel job is not a same-hour swap.
6. Rewire Scope
If the branch wiring feeding the panel is old, damaged, or undersized, addressing it is part of making the new panel safe. Most replacements do not require a rewire, but if your home has aged wiring, the estimate should separate panel work from wiring work so you can see the two scopes.
Ways to Manage the Cost
A few things help. Bundling related work - adding whole-home surge protection or an EV charger circuit while the electrician is already at the panel - is more efficient than separate visits. Financing can spread the cost, and sizing the panel correctly the first time avoids paying twice.
What Makes Fort Worth Panel Jobs Their Own Thing
Large stretches of Fort Worth and the surrounding mid-cities were built decades ago with 100-amp service that is undersized for a modern household, which makes the 100-amp-to-200-amp upgrade one of the more common panel jobs in this market - a meaningfully bigger scope than a same-size swap.
And because Oncor owns the meter and service drop across this area, almost every service upgrade carries the same disconnect-and-reconnect coordination step, no matter which electrician you hire.
Demand Is Rising, Which Pushes Upgrades
Two trends are driving more upgrades. Electric vehicles: a Level 2 charger adds one of the largest continuous loads in the house, and that is frequently the moment an older panel runs out of room. And severe weather, which pushes interest in standby generators - which also lean on the panel. Folding the panel upgrade into that project handles the load calculation, permit, and Oncor coordination once instead of twice.
Panel cost in Fort Worth is rarely just about the panel. It is the age of the home, the service size you need going forward, the utility's role, and what else you plan to add. An on-site estimate turns those variables into a real number.
