100 Amp to 200 Amp Upgrade Cost in 2026
Last updated: August 2026
Pricing for a 100A → 200A upgrade varies a lot depending on whether the job is mainly a panel replacement or a full electrical service upgrade. Here's what published cost guides report, what typically drives the difference, and a free calculator to compare your own quote.

100A to 200A Upgrade Cost
For a 100A → 200A upgrade, published reference pricing splits into two scopes. A panel replacement only — swapping the panel enclosure and breakers where the existing service entrance and meter can already support 200A — runs $1,300–$2,000. A full service upgrade, which also touches the meter base, service entrance conductors, and everything between the utility connection and your panel, runs $1,300–$3,000.
If you don't yet know which scope your project needs, budget toward the wider full-service range — it's the safer starting point until an electrician has looked at your existing service entrance and meter.

Panel Upgrade vs Full Service Upgrade
The single biggest factor in your final price is which of these two your project actually is.
Panel replacement only
$1,300–$2,000Your existing service entrance and meter can already support 200A — the work is limited to swapping the panel enclosure, main breaker, and branch breakers, and bringing grounding and bonding up to code.
Full service upgrade
$1,300–$3,000The actual capacity coming into your home needs to increase too — this pulls in the meter base, service entrance conductors, and possibly the mast/weatherhead and utility coordination, on top of the panel itself.
An electrician can usually tell which one applies to you from the rating on your existing meter base and service entrance — it's worth asking directly rather than assuming from the quoted panel size alone.
What Is Included in a 200 Amp Upgrade?
Commonly included in a 200A upgrade
- A new 200A-rated panel and main breaker
- New branch breakers sized to your existing circuits
- Grounding and bonding brought up to current code
- Panel labeling
- Permit filing and a final inspection sign-off
Added for a full service upgrade
- A new or upsized meter base
- New service entrance conductors sized for 200A
- Mast or weatherhead replacement, if the existing one can't support the upgrade
- Utility coordination for a temporary power disconnect/reconnect
- Panel relocation, if the new equipment doesn't fit in the existing spot
What Makes a 200 Amp Upgrade More Expensive?
- Meter work
- Replacing or upsizing the meter base — or coordinating a utility-side meter swap — adds cost beyond a simple panel swap.
- Service entrance changes
- Going to 200A often means larger conductors between the utility connection and your panel, not just a bigger box.
- Mast/weatherhead work
- If the mast or weatherhead where the service line attaches to the house isn't rated for the new capacity, it has to be replaced.
- Utility coordination
- Some upgrades require scheduling a power disconnect and reconnect with your utility company, which adds time and cost.
- Permits
- Permit fees and inspection scheduling vary by municipality and are sometimes billed separately from labor.
- Panel relocation
- Moving the panel to a new location adds conduit, wiring runs, and labor beyond an in-place replacement.
- Wiring condition
- Older or non-code-compliant wiring discovered mid-project can require extra work to bring the home up to code.
- Code upgrades
- Bringing grounding, bonding, or AFCI/GFCI protection up to current code can add scope your original quote didn't anticipate.
- Underground service
- Trenching and conduit work for underground service runs typically cost more than comparable overhead work.
How to Compare an Electrician Quote
- Get a written, itemized quote that separates labor, materials, and permit fees.
- Confirm whether the quote covers a panel replacement only or a full service upgrade.
- Ask whether permit fees and utility coordination are included or billed separately.
- Verify the electrician is licensed and insured for work in your area.
- Ask what happens — and what it costs — if wiring issues are found once work begins.
- Get at least one more quote so you have something to compare against.
Your quote may vary because of permits, utility requirements, meter work, panel location, wiring condition, code upgrades, and project complexity. Being above this reference range does not necessarily mean the quote is overpriced.
Frequently asked questions
How much does it cost to upgrade from 100 amps to 200 amps?
For a straightforward panel replacement with no meter or service-entrance changes, the reference range is $1,300–$2,000. If the project is a full service upgrade — new meter base, service entrance conductors, mast/weatherhead, and utility coordination — the reference range widens to $1,300–$3,000. These are estimated national reference ranges, not guaranteed local prices.
Is $5,000 too much for a 200 amp upgrade?
$5,000 is above our current national reference range, but that alone doesn't mean the quote is overpriced. It depends heavily on scope — a full service upgrade that includes extra work like panel relocation, underground service, or meter and code corrections can reasonably cost more than a straightforward panel swap. Use the calculator on this page with your specific details, and ask your electrician for an itemized breakdown so you can see exactly what's driving the price.
Why are 200 amp upgrade quotes so different?
Because "200 amp upgrade" can describe very different amounts of work: a panel-only replacement versus a full service upgrade involving the meter, service entrance, and utility coordination — plus factors like wiring condition, panel location, and whether service is overhead or underground. Two electricians quoting the "same" job may be pricing entirely different scopes of work.
Is a panel upgrade the same as a service upgrade?
Not necessarily. A panel upgrade can mean simply swapping the panel enclosure and breakers, while a full service upgrade also includes the meter base, service entrance conductors, and everything between the utility connection and your panel. Always confirm which one you're being quoted for.
Should I get multiple electrician quotes?
Yes. Because scope and pricing vary so much for this project, getting two or three itemized quotes — and confirming each one covers the same scope of work — is the most reliable way to know whether a price is fair.
Methodology and Sources
The reference ranges on this page are an early-stage (V1) national reference point, not a hyper-local estimate. They're informed by publicly published home-services cost guides covering electrical panel and service upgrades, cross-checked against each other rather than pulled from a single source. No ZIP-code or regional adjustment is applied yet — that's planned for a future version.
As more research is added, these ranges will be refined and expanded to cover more amperage combinations and project types — see the calculator above for which combinations currently have researched data.
