Electrical Panel Upgrade Cost in 2026
In 2026, upgrading a residential electrical panel costs about $1,600 on average, with most homeowners spending $1,200 to $2,000. A 100-amp to 200-amp upgrade runs $1,300 to $2,000; a same-amperage panel replacement $800 to $1,500; a 200-amp to 400-amp upgrade $2,000 to $4,000. Labor at $40 to $100 per hour is the largest cost component, and complex jobs with underground service or mast work run higher.
The electrical panel is the most important box in your house that you never think about until it becomes a problem. This guide covers what 2026 panel work costs by scope, what drives quotes up, and how to tell whether you need an upgrade or just a replacement.
What panel work costs in 2026
The national average for a residential panel upgrade in 2026 is about $1,600, with most homeowners spending $1,200 to $2,000. A like-for-like panel replacement (same amperage, new equipment) runs $800 to $1,500. The most common upgrade, 100 amps to 200 amps, costs $1,300 to $2,000 for a standard job. Stepping to 400-amp service runs $2,000 to $4,000, while complex 400-amp jobs with dual panels or utility trenching reach $8,000 to $12,000.
What is included in a standard upgrade: removal of the old panel, the new panel box and main breaker, a full set of circuit breakers, grounding and bonding updates, permit, utility disconnect/reconnect coordination, and inspection. What is often extra: service mast or weatherhead replacement, meter socket upgrades, trenching for underground service, drywall repair, and any wiring that must be brought up to current code once the panel is open.
Upgrade vs replacement: which do you need?
A replacement swaps a failing or obsolete panel for a new one at the same amperage: same service size, new equipment, lower cost. A upgrade increases service capacity, most often 100A to 200A, which means new service-entrance conductors and utility involvement. You need a replacement when the panel is damaged, obsolete (Federal Pacific, Zinsco), or out of breaker spaces. You need an upgrade when your loads exceed capacity: the EV charger, heat pump, hot tub, or addition that pushes the load calculation past what the service can deliver.
What drives the price
Labor is the biggest line. Electricians charge $40 to $100 per hour, and a panel swap takes 8 to 10 hours including the inspection window. Service type matters. Overhead service is straightforward; underground service often means trenching and conduit work. Location and access. Panels buried in finished closets, behind storage, or far from the meter cost more in labor. Code updates. Opening the panel can trigger requirements to update grounding, bonding, and nearby wiring to current code, especially in older homes. Market. High-cost metros run 50 to 100 percent above national averages; the same 100-to-200-amp job quoted at $1,600 nationally can bid $3,500 to $6,500 in expensive California or Northeast markets.
The quote checklist
A comparable bid lists: the panel make, model, amperage, and number of spaces; whether the scope is a replacement or a service upgrade (and the new service size); service-entrance conductor, meter socket, and mast work if any; the permit and inspection; the utility coordination plan; and the warranty on parts and labor. Get three bids, and make sure all three are bidding the same scope: replacement bids and upgrade bids are not comparable numbers.
The bottom line
Budget $1,300 to $2,000 for the standard 100-to-200-amp upgrade in 2026, $800 to $1,500 for a same-amp replacement, and more for 400-amp service or difficult conditions. The money goes mostly to skilled labor and to doing the job to code with a permit; this is the wrong place to hunt for the cheapest bidder.
