Electrical Panel Upgrade Cost Guide
How much does a 200A or 400A electrical panel upgrade cost in Maryland, DC, and Northern Virginia? A licensed electrician's honest breakdown.
In the DMV, a permitted 200A panel upgrade typically runs $2,400–$4,200 for a straightforward like-for-like swap, and $3,800–$6,500 when a meter base, mast, or service entrance also needs replacement. 400A services and dual-panel setups start around $6,500 and climb from there. Every quote from Flash Power LLC is written, itemized, and firm — no surprise line items on invoice day.

What drives the price
Panel cost is set by (1) amperage of the new service, (2) whether the meter base, mast, or service entrance cable needs replacement, (3) whether the utility must disconnect at the pole or transformer, (4) number of circuits and any AFCI/GFCI additions to meet current code, and (5) local permit and inspection fees, which vary by county.
What's included in a Flash Power LLC quote
Panel and breakers (Square D QO, Eaton BR/CH, or Siemens as spec'd), whole-home surge protection at the main, arc-fault and ground-fault protection where required by the current code cycle, permit and inspection fees, utility coordination for the temporary disconnect, and a labeled panel schedule you can hand to the next electrician.
Signs it's time to upgrade
A 100A service feeding a modern home with EV, heat pump, or induction range is usually undersized. Federal Pacific, Zinsco, and Challenger panels have documented failure histories and are worth replacing on their own merits. Rust, scorching, or double-tapped breakers are all reasons to schedule an inspection.
