Electrical panel upgrade costs vary widely because “panel upgrade” can describe several different projects. Replacing panel equipment, increasing service capacity, relocating equipment, changing meter components, or rebuilding part of the service entrance can produce very different totals.
For broad budgeting, Rewiring America currently uses about $2,000–$4,000 as a typical electrical panel upgrade reference. More complex projects can cost substantially more when the work extends beyond the panel into service conductors, meter equipment, underground service, trenching or utility infrastructure.
Electrical Panel Upgrade Cost at a Glance
| Project Type | Typical Scope | Cost Impact |
|---|---|---|
| Same-capacity panel replacement | Replace aging, damaged or obsolete panel equipment without increasing service capacity | Usually lower than a service-capacity increase |
| Panel-focused upgrade | Install new panel equipment where the existing service arrangement can remain | Often remains in the low-to-mid-thousands range |
| 100A to 200A service upgrade | Panel plus service equipment or conductors needed to support higher capacity | Usually costs more than panel-only work |
| Panel or service-equipment relocation | Move equipment to a different location | Adds conductor, conduit, labor and possible finish work |
| Meter or service-entrance changes | Additional meter equipment, service conductors, grounding, bonding or entrance work | Can increase the project substantially |
| Underground or utility infrastructure work | Trenching, underground conductors or utility-side infrastructure changes | Can become a major project cost |
The key question is not simply what the average upgrade costs, but what work the estimate actually includes.
Why Electrical Panel Upgrade Prices Vary
A panel is only one part of the electrical service. Some projects stop largely at the panel, while others extend into the meter, service conductors, grounding and bonding system, service entrance or utility connection.
That difference explains why published prices can appear inconsistent. A contractor pricing a straightforward panel-focused project may be describing a fundamentally different job from one that includes a service-capacity increase, meter work and utility coordination.
Utility conditions can widen the gap further. PG&E, for example, currently estimates roughly $3,000–$8,000 for a full panel upgrade with overhead service in its territory and notes that some underground-service projects can reach $20,000 or more when trenching is required.
Those are PG&E-specific examples, not national averages. They show how quickly the total can rise when work extends beyond the panel itself.
Electrical Panel Cost by Amperage
Higher-capacity equipment generally costs more, but amperage alone does not determine the final project price. Existing service conditions and installation scope can matter just as much.
| Panel Capacity | Installed Cost Reference | Context |
|---|---|---|
| 100 amp | About $800–$1,500 | Common replacement range where additional service capacity is not part of the project |
| 200 amp | About $1,300–$3,000 | Panel-and-installation reference; a full 100A-to-200A service upgrade may cost more |
| 300 amp | About $1,800–$3,500 | Higher-capacity installations can require more extensive service equipment |
| 400 amp | About $2,000–$4,000 | Larger residential services can involve more complex equipment and design |
These figures are useful as installed panel references, not universal prices for complete service upgrades. A 200 amp panel installed where the existing service arrangement can remain is a different project from converting an older 100 amp service to full 200 amp capacity.
For the detailed cost breakdown of that specific project, see our 200 amp panel upgrade cost guide.
Panel Replacement vs. Capacity Upgrade
A same-capacity panel replacement and a service-capacity upgrade should not be priced as interchangeable projects.
A replacement may change aging, damaged or obsolete equipment while keeping the same service capacity. An upgrade increases available capacity and can require additional work beyond the panel.
For replacement-only pricing, see our electrical panel replacement cost guide. If you are deciding which project applies to your home, see electrical panel upgrade vs. replacement.

What Actually Increases Electrical Panel Upgrade Cost?
The largest price increases usually happen when the work extends beyond the panel itself. Service conductors, meter equipment, relocation, underground work and utility requirements can turn a relatively contained panel project into a much larger electrical-service upgrade.
Service Conductors and Service-Entrance Work
If the existing service conductors or entrance equipment cannot support the planned capacity, they may need to be replaced or modified. That adds labor, materials and coordination beyond a basic panel installation.
Meter Equipment
Meter-socket or meter-main changes can add meaningful cost. Whether existing meter equipment can remain depends on the installation, equipment rating and serving utility requirements.
Panel or Service-Equipment Relocation
Relocating equipment is usually more involved than replacing it in a suitable existing location. The work may require longer conductor runs, new conduit, structural changes and interior or exterior finish repairs.
Underground Service and Trenching
Underground service can become a major cost driver when excavation, conduit, conductor replacement or utility-side work is required. In those projects, the expensive part may be the infrastructure around the panel rather than the panel itself.
Existing Wiring and Electrical Conditions
A panel upgrade does not automatically require a whole-house rewire. Existing branch-circuit wiring can often remain when it is suitable for the circuits it serves and does not require replacement as part of the permitted work.
Additional repairs may still be required when the project exposes damaged wiring, grounding or bonding deficiencies, incompatible equipment or other conditions that must be corrected within the scope of the alteration.
If you are trying to determine whether the work stops at the panel or extends through the home’s wiring system, see our guide to panel upgrades vs. rewiring a house.
Permit, Inspection and Utility Costs
Panel and service alterations commonly involve local permits and inspections. Projects that affect the service connection may also require coordination with the serving utility.
Some contractor estimates include permit administration and inspection fees, while others list them separately. Check the estimate before comparing prices.
For a closer look at permitting expenses, see our electrical panel upgrade permit cost guide.
Utility Coordination Can Affect Cost and Timing
A service-capacity increase may require utility review, meter work, disconnect and reconnect scheduling, or changes to the service connection.
PG&E, for example, separates panel changes, added-load upgrades, meter work, underground service and disconnect/reconnect requests within its residential project process. Other utilities use their own procedures, but the example shows why apparently similar projects can require very different work outside the home.
Can You Avoid a Larger Service Upgrade?
Sometimes. If the project is being triggered by a new electrical load such as EV charging, HVAC equipment or other electrification work, the first question is whether the existing service actually lacks capacity.
A load calculation can show whether the proposed equipment can be supported without increasing the service size. In some installations, approved load-management equipment may also help control new demand.
Load management is not a substitute for every panel or service upgrade. It is an option to evaluate when capacity — rather than damaged or unsuitable equipment — is the reason for considering a larger service.
Before increasing service capacity solely for a new load, see our electrical panel load calculation guide.
Electrical Panel Tax Credits and Incentives in 2026
Older articles may still refer to the former federal tax credit for qualifying electrical panel improvements.
The federal Energy Efficient Home Improvement Credit under Section 25C is not available for qualifying property placed in service after December 31, 2025. A panel upgrade completed in 2026 therefore should not be budgeted around that former federal credit.
State, local and utility programs may still provide incentives for certain electrification projects. Eligibility depends on the program and location, so any available incentive should be verified before it is included in the project budget.

How to Compare Electrical Panel Upgrade Quotes
When two electrical panel upgrade estimates are far apart, first confirm that the contractors are pricing the same work.
One estimate may cover primarily the panel, while another includes service conductors, meter equipment, grounding and bonding work, utility coordination, permits, relocation, trenching or repairs. The totals are only directly comparable when the included scope is comparable.
Compare these items line by line:
- the exact panel or service equipment being installed;
- whether the service capacity is increasing;
- main breaker and branch breakers included;
- service-conductor work;
- meter or meter-main changes;
- grounding and bonding work;
- permit and inspection fees;
- utility disconnect and reconnect coordination;
- panel or service-equipment relocation;
- trenching, conduit or underground work;
- drywall, siding or other finish repairs;
- how additional corrective work will be priced if discovered during the project.
If an item is unclear, ask whether it is included, excluded or subject to an additional charge before accepting the estimate.
When to Use the 200 Amp Upgrade Cost Guide
If the project specifically involves increasing a home from 100 amps to 200 amps, evaluate it as a service-capacity upgrade rather than a simple panel replacement.
That work can extend beyond the panel into service conductors, meter equipment, the service entrance and utility coordination. See our 200 amp panel upgrade cost guide for the detailed pricing and scope breakdown.
Would a Subpanel Solve the Problem Instead?
A subpanel can add breaker spaces and distribute circuits to another part of the property, but it does not increase the electrical service capacity available to the home.
If the existing service has enough capacity and the problem is limited to circuit space or distribution, a subpanel may be worth evaluating. If the home lacks capacity for the planned loads, adding a subpanel does not solve that limitation.
For costs and use cases, see our electrical subpanel cost guide.
How Much Should You Budget?
Use published cost ranges as planning references, not substitutes for a project-specific estimate.
A contained panel project may remain in the low thousands, while a service-capacity increase, relocation, underground work or utility infrastructure can push the total much higher. Build the budget around the actual electrical scope rather than a single national average.
Separate the base electrical work from excluded, optional or condition-dependent items when reviewing estimates. That makes it easier to see whether a higher quote reflects more work or simply a higher price for the same scope.
Frequently Asked Questions
Is replacing an electrical panel the same as upgrading it?
No. A replacement can keep the same service capacity while changing aging, damaged or obsolete equipment. An upgrade may increase available capacity and require additional service work. See our electrical panel upgrade vs. replacement guide for the full distinction.
Does a larger electrical panel automatically mean more service capacity?
No. The panel rating alone does not establish the capacity of the incoming electrical service. The service equipment, conductors and utility connection must support the intended capacity.
Can a panel upgrade cost more than $10,000?
Yes. Major service work, relocation, underground conductors, trenching or utility infrastructure can push a project well beyond ordinary panel-focused budgets. In those cases, much of the additional cost comes from work outside the panel itself.
Should I get multiple electrical panel upgrade quotes?
For a significant panel or service project, multiple written estimates can help identify differences in scope, exclusions and utility responsibilities. Compare what each contractor is providing rather than choosing solely by the lowest total.
Bottom Line
Electrical panel upgrade cost depends largely on how far the required work extends beyond the panel. Service-capacity increases, meter work, relocation, underground service and utility infrastructure can all change the project substantially.
Define the scope first, then compare estimates based on the same panel, service, meter and utility work. That gives you a much more useful comparison than relying on a single national average.
