Cost to Replace an Electrical Panel in 2026: Upgrade Price by Amperage
The cost to replace electrical panel varies by amperage and whether a service upgrade is needed. Replacing a 200-amp electrical panel costs $1,500 to $4,500 installed in 2026. Upgrading from a 100-amp to 200-amp service costs $1,800 to $5,500 because it typically requires replacing the service entrance cable and meter base in addition to the panel. The cost to replace an electrical panel increases significantly if the utility company’s meter socket needs replacement, if the service entrance cable from the meter to the panel must be rerouted, or if the existing wiring to branch circuits needs updating to current code.
The electrical panel is the nerve center of a home’s electrical system: every circuit in the house originates here. Most homeowners never think about it until a breaker trips repeatedly, a circuit cannot be added, or an electrician flags it during a home inspection. Panel replacement is one of the few home improvement projects that is not optional once a safety issue is identified. It requires permits, inspections, and a licensed electrician in every US jurisdiction.

Signs Your Electrical Panel Needs Replacement
Immediate safety concerns
Panels that require immediate replacement: Federal Pacific Electric (FPE) Stab-Lok panels (known defective breakers that fail to trip under overload conditions; a significant fire risk); Zinsco or GTE-Sylvania panels (similar breaker failure issue); any panel with evidence of burning, melting, or scorching around breakers or the main bus bar; fuse boxes in homes where the fuse size has been increased above the rated wire size (a fire hazard called overfusing). These are not “consider replacing” situations; they are active safety risks that electricians and insurance companies treat as requiring immediate action.
Capacity and functionality concerns
Upgrade or replace when: breakers trip frequently under normal household loads; there are no open breaker slots for adding new circuits (EV charger, hot tub, home office, kitchen appliance circuit); the panel is 25 to 40 years old and at the end of its useful life; a home inspection finds the panel flagged as undersized, outdated, or potentially problematic; or you are adding significant new electrical load (EV charger typically requires 48 to 60 amps dedicated circuit; a central HVAC system replacement may require more capacity than the existing panel provides). For the HVAC load specifically, our HVAC replacement cost guide covers the electrical requirements of different system types. For adding lighting circuits, our recessed lighting cost guide covers the electrical work alongside the fixture cost.
What Drives Electrical Panel Replacement Cost
| Additional work | Typical add-on cost | When required |
|---|---|---|
| Service entrance cable replacement | $500 to $1,500 | Upgrading service amperage; old SE cable |
| Meter socket replacement | $300 to $800 | Utility upgrade; damaged or old socket |
| Grounding electrode system | $200 to $600 | NEC 2023 compliance; often required on older homes |
| AFCI breakers (arc-fault) | $30 to $60 per breaker | NEC requires for bedrooms, living areas |
| GFCI breakers | $30 to $55 per breaker | NEC requires for bathrooms, kitchen, exterior |
| Subpanel addition | $500 to $1,500 | Garage, workshop, or addition circuits |
Permits and Inspection Process
Electrical panel replacement always requires a permit in every US jurisdiction. This is not optional and is not something to bypass: an unpermitted panel replacement that fails during a home inspection or fire investigation carries serious liability, voids homeowner insurance claims related to electrical fires, and may require removal and reinstallation at full cost. The process: the licensed electrician obtains the permit before starting work, installs the new panel, calls for an inspection, the inspector verifies code compliance, and the inspection is signed off. The utility company then reconnects the meter (if it was pulled for the installation). This process typically takes 1 to 3 days total.
Three Real Panel Replacement Projects
Example 1: 200-amp upgrade for an EV charger in Denver, Colorado
A homeowner with a 100-amp panel in a 1,800 sq ft home adding a Level 2 EV charger (48-amp dedicated circuit). The existing 100-amp panel had no available breaker slots and was undersized for the added load. Scope: replace 100-amp panel with 200-amp service, including new meter socket and service entrance cable (the existing 100-amp SE cable was undersized for 200-amp service). New 200-amp panel (24-space): $280. New 200-amp service entrance cable and meter socket: $850. Labor (two electricians, full day): $1,200. Permit and inspection: $180. Total: $2,510. The EV charger circuit itself was installed at the same time: 60-amp dedicated circuit, $380. Combined project: $2,890.
Example 2: FPE Stab-Lok replacement in Atlanta, Georgia
A homeowner who purchased a 1970s home with an original FPE Stab-Lok panel flagged during the inspection as a known safety hazard. Insurance company required replacement as a condition of coverage. Scope: replace 150-amp FPE panel with a new 200-amp panel (upgrading to meet current load). New 200-amp panel (30-space, all new breakers): $320. AFCI breakers required by NEC for bedrooms and living areas: 8 x $45 = $360. GFCI breakers for bath, kitchen, exterior circuits: 4 x $40 = $160. Labor (two electricians, 6 hours): $900. Permit and inspection: $145. Total: $1,885. Insurance premium reduction from removing the flagged panel: $180/year. The homeowner also received a quote from the prior insurer who had been charging a “knob-and-tube/FPE surcharge” of $340/year which was eliminated after the new panel installation.
Example 3: 400-amp service for a home with large electrical loads in Phoenix, Arizona
A homeowner with a 4,200 sq ft home with a pool, hot tub, 3-car garage with two EV chargers, and a large whole-house HVAC system requiring a 400-amp service upgrade from an existing 200-amp panel. Scope: install a 400-amp main disconnect, two 200-amp sub-panels (one for HVAC and pool equipment, one for the main house), and replace the service entrance conductors from the utility transformer connection. Main disconnect and two 200-amp sub-panels: $1,100. Service entrance conductors (underground, 100-foot run): $2,800. Labor (master electrician plus apprentice, 2.5 days): $3,200. Permit (large commercial-scale residential): $480. Total: $7,580. The utility also required a new pad-mount transformer to support the 400-amp service, which the utility installed at no charge to the homeowner as part of their service extension program.

Calculate Panel Upgrade Cost →Frequently Asked Questions About Electrical Panel Replacement
How much does it cost to replace an electrical panel?
Replacing a 200-amp electrical panel costs $1,500 to $4,500 installed in 2026. Upgrading from 100-amp to 200-amp service costs $1,800 to $5,500 because it often requires replacing the service entrance cable and meter socket in addition to the panel itself. A 60-amp to 200-amp upgrade (common in older homes) costs $2,500 to $7,000. Always get three quotes from licensed electricians and verify that each quote includes permits, all required code upgrades, and the service entrance cable if amperage is increasing.
Do I need a 100-amp or 200-amp electrical panel?
A 200-amp service is the modern standard for new residential construction and is recommended for any home renovation. 100-amp service is sufficient for a modest home with gas appliances (range, dryer, water heater) but is undersized for homes with all-electric appliances, central air conditioning, an EV charger, or a hot tub. If you are adding any large electrical load or have fewer than 4 to 6 available breaker slots, upgrade to 200-amp now rather than upgrading again in 5 years when another large load requires it.
How long does electrical panel replacement take?
A straightforward panel replacement (same amperage, no service entrance upgrade) typically takes 4 to 8 hours for an experienced electrical crew. An amperage upgrade that requires new service entrance cable and meter socket takes 6 to 10 hours plus utility reconnection time. The power is off at the panel for the duration of the installation; most installations are completed within one day so the home is without power for 6 to 10 hours. If a utility reconnect appointment is needed, power may be off for up to 24 hours.
Is a Federal Pacific Stab-Lok panel really dangerous?
Yes. Federal Pacific Electric Stab-Lok breakers have documented failure rates in independent testing: they fail to trip under overload conditions at much higher rates than code-compliant breakers. When a breaker fails to trip, the circuit remains energized under a fault condition, which can ignite wiring insulation and cause fires. The Consumer Product Safety Commission (CPSC) investigated FPE panels in the 1980s. Many home inspectors and insurance companies treat FPE panels as presumptive fire hazards requiring replacement. Homeowner insurance may be declined or surcharged for homes with known FPE panels.
Can I replace my own electrical panel?
Electrical panel replacement is a licensed electrician job in every US jurisdiction, not a DIY project. The work involves high-voltage service entrance conductors that remain energized even when the main breaker is off; only the utility meter removal de-energizes the service conductors, and utilities require licensed personnel or a permit for meter disconnection. DIY panel replacement is illegal in most jurisdictions, will not receive a permit or inspection, and voids homeowner insurance coverage for any electrical fire or damage that results from unpermitted work.
What is an AFCI breaker and do I need them?
Arc-Fault Circuit Interrupter (AFCI) breakers detect arcing faults in wiring (loose connections, damaged wire insulation) and trip before the arc causes a fire. The National Electrical Code (NEC 2023) requires AFCI protection for bedroom circuits, living rooms, hallways, and kitchens in new construction and when replacing panels. AFCI breakers cost $30 to $60 each versus $5 to $15 for standard breakers, significantly increasing the cost of a full panel replacement that includes all new breakers. Many jurisdictions have adopted NEC 2023 or 2020; check with your local building department for the code cycle in effect.
How do I know what size electrical panel I need?
A licensed electrician performs an electrical load calculation (based on NEC Article 220) that totals the amperage draw of all connected loads: general lighting, small appliances, fixed appliances (range, dryer, HVAC, water heater, etc.), and any planned additions. The result determines the minimum service size required. As a general rule: 100-amp service for small homes under 1,000 sq ft with gas appliances; 150 to 200-amp for standard homes with electric appliances; 200-amp for homes with EV chargers or large HVAC; 400-amp for very large homes or homes with significant special electrical equipment.
Will my homeowner insurance cover electrical panel replacement?
Standard homeowner insurance does not cover electrical panel replacement as a maintenance or upgrade expense. If a covered peril (fire, lightning strike, covered power surge) damages the panel, the insurance may cover the replacement cost subject to the deductible. Some insurers will not insure homes with specific panel types (FPE Stab-Lok, Zinsco, or aluminum branch circuit wiring) and require upgrades as a condition of coverage. If your insurer asks about the panel type during underwriting, always answer honestly; misrepresentation can result in claim denial.
