If you are researching the electrical panel upgrade cost for your Atlanta-area home, here is the short answer: most homeowners pay between $1,800 and $4,500 for a straightforward panel swap, while a full service upgrade from 100 amps to 200 amps typically runs $2,500 to $6,000+. Those ranges cover the new panel, breakers, labor, permits, and inspection, but your final number depends on the age of your wiring, the location of your panel, whether Georgia Power needs to disconnect and reconnect service, and a handful of other factors we will break down below.
This guide walks you through exactly what is included in a panel upgrade, what each piece costs, how long the work takes, and how to tell whether your home actually needs one. Every dollar figure listed here is a typical Atlanta-area estimate, not a fixed quote, because every home is different.
What Is Included in a Panel Upgrade?
When electricians talk about a “panel upgrade,” they are usually referring to several coordinated tasks, not just bolting a new box to the wall. Here is what a complete electrical panel upgrade and replacement typically includes:
New Panel and Circuit Breakers
The old panel enclosure is removed, and a new, code-compliant panel is installed. This includes the main breaker, bus bars, and individual circuit breakers matched to every circuit in your home. If you are moving from a 100-amp panel to a 200-amp panel, the new enclosure will be physically larger and will accept more breaker slots, which gives you room for future additions like EV chargers, heat pumps, or home additions.
Meter Base and Service-Entrance Conductors
A service upgrade often requires a new meter base (the enclosure on the exterior of your home where Georgia Power connects) and new service-entrance conductors, which are the heavy cables that run from the meter to the panel. If you are only doing a like-for-like panel swap at the same amperage, the existing meter base and conductors may stay in place, but your electrician will inspect them to confirm they are still safe and up to code.
Grounding and Bonding
Current National Electrical Code (NEC) requirements for grounding are stricter than what many older Atlanta homes were built to. During an upgrade, your electrician will verify that the grounding electrode system, including ground rods, water pipe bonds, and the grounding electrode conductor, meets the 2023 NEC standards adopted by Georgia. Corrective work is included or quoted separately if needed.
Permit and Inspection
Fulton, DeKalb, Gwinnett, Cobb, and virtually every metro-Atlanta jurisdiction require an electrical permit for panel work. Your electrician pulls the permit, schedules the inspection with the local authority having jurisdiction (AHJ), and handles any communication with the inspector. Georgia Power will also need to schedule a disconnect and reconnect if the service-entrance conductors are being replaced.
Labeling, Circuit Mapping, and Cleanup
Once the new panel is energized and passes inspection, every breaker should be clearly labeled so you know exactly which circuit controls which part of your home. A responsible electrician also cleans up all debris, removes the old panel, and walks you through the finished work.
Electrical Panel Upgrade Cost in the Atlanta Area
Below are typical price ranges for each component. Keep in mind that these are estimates based on common Atlanta-area projects. Your price depends on your home’s age, panel location, amperage needs, local permit fees, and the condition of existing wiring.
- Permit fees: $75 to $250 (varies by county and scope of work)
- New panel, main breaker, and individual breakers: $400 to $1,200 (cost varies with brand, amperage rating, and number of spaces)
- Labor for a like-for-like panel swap (same amperage): $1,000 to $2,500
- Full service upgrade from 100A to 200A (including new meter base, service-entrance conductors, grounding updates, panel, breakers, and labor): $2,500 to $6,000+
- Panel relocation (moving the panel to a different wall or room): $1,500 to $3,500 on top of the upgrade cost, depending on distance and finish work required
- Whole-home surge protector (commonly added during an upgrade): $250 to $500 installed
These numbers do not include major rewiring. If your inspector or electrician discovers knob-and-tube wiring, aluminum branch-circuit wiring, or other serious issues behind the walls, that work will be scoped and priced separately.

100 Amp vs. 200 Amp vs. 400 Amp: Which Do You Need?
100-amp service was standard in homes built before the mid-1970s. It can handle basic lighting, a few kitchen appliances, and a single HVAC system, but it will struggle with modern electrical loads. If you have no plans for major additions and your current usage is modest, a 100-amp panel swap may suffice, but most electricians will recommend stepping up to 200 amps while the panel is already open.
200-amp service is the current standard for most single-family homes in the Atlanta metro. It comfortably supports central HVAC, an electric range, an electric dryer, a hot tub, an EV charger, and a home office without straining. If you are building new or upgrading an older home, 200 amps is almost always the right choice.
400-amp service is typically reserved for very large homes (4,000+ square feet), homes with multiple HVAC systems, full workshop setups, or properties with detached buildings that draw significant power. A 400-amp service usually involves two 200-amp panels fed by a single 400-amp meter base and disconnect. Costs start around $8,000 and can climb well above $12,000 depending on complexity.
Your electrician will perform a load calculation, following NEC Article 220, to recommend the right amperage for your household. This is not guesswork; it is a math-based process that accounts for every appliance and circuit in the home.
How Long Does an Electrical Panel Upgrade Take?
Most panel upgrades are completed in a single day, typically 6 to 10 hours of on-site work. Here is a general timeline:
- Morning: Georgia Power disconnects service (if required). The electrician removes the old panel and prepares the mounting area.
- Midday: The new panel, breakers, and wiring are installed. Grounding and bonding connections are made or updated.
- Afternoon: Circuits are tested, breakers are labeled, and the electrician requests final inspection. Georgia Power reconnects service once the inspection passes.
Your power will be off for most of the day during a full service upgrade. If only the panel is being swapped at the same amperage, the outage may be shorter. In some jurisdictions, the inspection can happen the same day; in others, it may be scheduled for the following business day, which means a brief delay before Georgia Power reconnects.
Panel relocations or projects that involve running new conduit through brick, concrete, or finished walls may extend the timeline to a day and a half or two days.
Signs You Need an Electrical Panel Upgrade
Not every home needs an upgrade right away, but the following warning signs mean you should have a licensed electrician evaluate your panel sooner rather than later:
- Frequent breaker trips even when you are not running heavy loads
- Flickering or dimming lights when appliances cycle on
- A Federal Pacific (FPE) or Zinsco panel, both of which have well-documented safety concerns
- Fuses instead of breakers, indicating a panel that is likely 50+ years old
- Double-tapped breakers or tandem breakers used beyond the panel’s rated capacity
- Burn marks, melted plastic, or a hot/burning smell coming from the panel area
- You are adding a major load such as an EV charger, heat pump, pool equipment, or home addition and your current panel does not have the capacity
If any of these apply, do not wait. Panel-related electrical failures are a leading cause of residential fires.
Frequently Asked Questions
How much does it cost to upgrade from 100 amps to 200 amps in Atlanta?
Most homeowners in the Atlanta metro pay between $2,500 and $6,000 for a complete 100-to-200-amp service upgrade, including the new panel, meter base, service-entrance conductors, permits, and inspection. Homes with difficult panel locations, long conduit runs, or outdated grounding systems will land on the higher end.
How long will my power be off during the upgrade?
Expect 6 to 10 hours without power for a full service upgrade. For a same-amperage panel swap, the outage is often shorter, around 4 to 6 hours. Plan to keep refrigerators and freezers closed, and charge devices the night before.
Do I need a permit for a panel upgrade in Georgia?
Yes. Every metro-Atlanta county requires an electrical permit for panel replacements and service upgrades. A licensed electrician handles the permit application and coordinates the inspection so you do not have to.
Can I upgrade my panel myself to save money?
Legally, Georgia homeowners can pull a homeowner’s permit for work on their own primary residence, but panel and service-entrance work involves direct contact with utility-side conductors that carry lethal current. This is not a DIY project. Improper connections can cause fires, void your homeowner’s insurance, and create code violations that surface during a future home sale.
Will upgrading my panel increase my home’s value?
A modern, properly sized panel is a positive signal to home inspectors and buyers. It will not add dollar-for-dollar value the way a kitchen remodel might, but it removes a common red flag that can stall or kill a sale, especially if the old panel was an FPE, Zinsco, or fuse box.
