How much a panel upgrade costs in 2026, and whether your quote is fair

From the electrician: what I want you to know about panel work

A panel upgrade is rarely about running out of breaker slots. It happens because the system was designed for a very different level of power use. Add an EV charger, an electric dryer, an induction range, an addition, a hot tub, or just a couple of people working from home every day, and an older, smaller service starts to show its limits quickly.

I see plenty of houses where the panel still works on paper but the system is already stretched: two wires under one breaker screw, tandem breakers in every open slot, neutrals that have overheated, old cloth-covered wire landed on newer breakers. That is usually what is really behind the call. Many people assume the panel itself gave out. Most of the time the household simply grew past what the service was built for.

In my experience the box on the wall is not where the hidden cost is. Utility coordination and access are. Moving the meter, replacing the mast, bringing grounding up to current code, or meeting a utility's service entrance requirements can each push a quote up quickly. Finished space around the panel complicates things more than people expect, and an open, unfinished mechanical room can save a lot of labor compared with a cramped, finished utility closet.

I check the brand right away. A Federal Pacific or Zinsco panel gets a replacement recommendation from me every time, because I have watched breakers in both fail to trip under load. That comes from the field, not from internet scare stories. Bus bars that show heat damage, or moisture getting in near the service entrance, get the same response.

Online forums often leave people thinking any new EV charger or appliance means a bigger service. Sometimes it does. Often, when I run a proper load calculation, the service you already have turns out to be enough, and I have watched people spend a lot on an upgrade that smarter load management could probably have avoided.

On a quote, I want the service size spelled out, the grounding work specified, the permit cost shown, and some mention of coordinating with the utility. "Replace panel as needed" usually tells me the contractor has not fully worked out the job.

For my own house, I would install a full-size service with spare spaces for circuits I may add later, even when the current load does not need it. The extra cost during the install is usually small next to opening everything up again a few years on, when the next large appliance or addition shows up.
