Electrical panel replacement cost is one of the most expensive residential electrical repairs, but it’s also one of the most critical for safety. In 2026, most homeowners replacing an outdated, overloaded, or unsafe electrical panel can expect costs well into the four-figure range—especially if upgrades are required.
If you’re dealing with frequent breaker trips, heat, buzzing, or burning smells, start with the Symptoms Index or the Start Here page to confirm whether the issue is panel-related.
Quick answer: What does it cost to replace an electrical panel in 2026?
Most full panel replacements fall between $1,500 and $4,500. Smaller or straightforward swaps may land on the low end, while service upgrades, rewiring corrections, or larger homes can push costs significantly higher.
The wide range exists because a “panel replacement” is rarely just a box swap—it often includes code updates, breaker upgrades, grounding improvements, permits, and inspections.
Electrical panel replacement cost by panel size
- 100-amp panel: $1,500–$2,500 (common in older homes)
- 150-amp panel: $2,000–$3,500
- 200-amp panel: $2,500–$4,500 (modern standard for most homes)
If you’re unsure what size panel you currently have—or whether it’s overloaded—see Wiring & Circuit Issues for common warning signs.
What’s included in a panel replacement quote?
- Removal of the old panel and breakers
- Installation of a new panel and main breaker
- Re-terminating existing circuits safely
- Grounding and bonding upgrades (if required)
- Electrical permits and inspections
Signs you may NEED panel replacement (not just breaker repair)
- Breakers that feel hot or smell like burning plastic
- Buzzing or humming sounds from the panel
- Scorch marks or corrosion inside the panel
- Frequent tripping with no clear load issue
- Federal Pacific, Zinsco, or other recalled panel brands
Many of these symptoms are covered in detail under Electrical Smells, Sounds & Safety Concerns.
Panel replacement vs. panel upgrade: what’s the difference?
A replacement means swapping an unsafe or failing panel with a modern equivalent. A service upgrade increases amperage (for example, from 100A to 200A) and often requires utility coordination, meter work, and grounding changes.
Why electrical panel replacement is expensive
- Labor intensity: Panels require hours of careful circuit labeling and reconnection
- Permits & inspections: Mandatory in most jurisdictions
- Code compliance: Older homes often need grounding or bonding upgrades
- Risk level: Panels are the highest-risk area of the electrical system
If breakers are warm, tripping, or failing to reset, review Breaker & Panel Issues to determine whether replacement is truly necessary.
Can you delay panel replacement?
In some cases—such as a single bad breaker or minor load imbalance—replacement can wait. However, signs like burning smells, arcing sounds, or known unsafe panel brands should be treated as urgent.
If your home has partial power loss or entire circuits dropping out, also review Power Loss & Intermittent Issues.
How to reduce panel replacement cost safely
- Bundle future electrical upgrades during the panel replacement
- Confirm amperage needs before upsizing
- Get multiple licensed electrician quotes
- Ask for a load calculation to avoid overbuilding
