Who this is for
- You have a home, a business, or a light industrial property in Fairfield County on 100 amps, or an older 200-amp panel that is full.
- Breakers trip when the dryer, AC, or microwave stack.
- You want a Level 2 EV charger, a standby generator, or a service upgrade, and you want one licensed electrician to price it in writing.
- You can take a callback Mon-Fri 8-4.
Panel replacement and new circuits
The same form takes estimate requests to replace a breaker box (the electrical panel) or to add a new circuit, such as a dedicated line for an EV charger or a large appliance. Describe the work on the form. The assigned licensed contractor reviews each request and confirms whether the job fits. Panel size comes from a load calculation, not from this page: see 100A vs 200A, the cost guide and the warning signs.
Who should leave
- You want 24/7 emergency dispatch for active fire, smoke, or sparking. Call 911.
- You want five contractors bidding your phone number.
- You are shopping a lead marketplace.
What happens to your request
You fill one form. The request goes to the assigned contractor (CT Lic. ELC.0200504-E1). The assigned contractor's office calls Mon-Fri 8-4. You get a site visit and a written estimate before anyone touches the panel. Permit, town inspection, and utility coordination stay in the written scope. Your number is not shared.
Planning ranges, not a quote
These are the third-party ranges already published on this site. Connecticut contractor figures for panel and service work span about $1,800–$4,500. A licensed electrician prices the work after a site visit. *
| Work | Planning range | Where it comes from |

| Like-for-like panel swap | $1,800–$3,000 | Connecticut contractors, 2025–2026 |
| 100A to 200A with service entrance, meter socket and grounding | $2,800–$4,500 | Connecticut contractors, 2025–2026 |
| Panel alone | $1,300–$3,000 | National guides |
| Level 2 EV charger, before any panel work | $700–$2,000 | National installed range |
Underground runs, a Federal Pacific or Zinsco changeout, and long conduit push higher. Like-for-like swaps sit lower. Sources and what moves the number are in the cost guide and the EV charger guide.

- Written price before work starts
- Town permit and inspection handling
- Eversource or UI coordination when the service side needs it
- 200-amp panel upgrade, Service upgrade, EV charger, Standby generator, or Other
Still on 100 amps?
A lot of Fairfield County houses were wired for a quieter kitchen and one AC. Then you added a dryer stack, a heat pump, an EV in the garage, or a generator pad, and the panel starts telling on you. Lights dip. Breakers trip. The EV guy says the panel is full.
You do not need five "free estimate" calls from strangers. You need one licensed Connecticut electrician who will look at your panel, run the load numbers, and put a price in writing.
That is the assigned contractor. CT Lic. ELC.0200504-E1. Mon-Fri 8-4 callbacks. We do not sell your information.
Fill out the form with what you are planning (200-amp panel upgrade, Service upgrade, EV charger, Standby generator, or Other). The assigned contractor calls back Mon-Fri 8-4. If the job is real, you get a site visit and a written estimate. If you do not need an upgrade, you should hear that too.
Guides, each with its sources and dates: panel upgrade cost, 100A vs 200A, EV charger, generator, warning signs. Permit offices and local filing rules are on the town pages.
Questions homeowners ask
Who actually does the work?
ElectricalPanelUpgrade.net is operated by AEQR.ai. Requests in this area go to one assigned contractor, CT Lic. ELC.0200504-E1. Not a lead auction. Any electrical contract and work are between you and that contractor. The license number is in the disclosure at the bottom of this page.
When does a person call back?
The form can be sent any time. The assigned contractor calls back Mon-Fri 8-4 with a written estimate. The phone number on this page is answered any time by our automated assistant, which takes your details; a person calls back Mon-Fri 8-4. Calls may be recorded.
How much does a 200-amp panel upgrade cost in Connecticut?
Connecticut contractors published 2025–2026 ranges of roughly $1,800–$3,000 for a like-for-like panel swap and $2,800–$4,500 when the service entrance, meter socket and grounding are upgraded from 100A to 200A. National guides run $1,300–$3,000 for the panel alone. See the cost guide for sources and what moves the number.
Do I need a permit?
Yes. Every Connecticut town requires an electrical permit and a final inspection for a panel or service upgrade, and the work must be done by a licensed contractor unless you own and occupy the single-family home yourself (CGS §20-340). Fees on a typical panel job run roughly $35–$150 depending on the town, and scale up with job value. See the town-by-town permit guide. Your assigned contractor pulls the permit and schedules the inspection.
Will my power be off?
For a panel replacement, yes. Typically 6–10 hours, usually finished the same day. For a full service upgrade the utility (Eversource or United Illuminating) is involved in the disconnect and meter step; the electrician must file a service request in advance.
Is there a rebate or tax credit in 2026?
The federal $600 panel credit (§25C) ended for work placed in service after December 31, 2025, and the federal EV charger credit (§30C) ended June 30, 2026. Eversource and UI still pay EV managed-charging incentives, and a $1,500 charger/wiring rebate exists for income-qualified households and for addresses in designated High Poverty, Low Opportunity areas. Details in the 2026 rebates guide.
What happens after I submit?
You get a confirmation page. The assigned contractor's office calls the number you gave to ask a few questions and set up a site visit. The estimate itself is prepared by a licensed electrician after seeing the panel.
Will I get text messages?
Only if you tick the separate, optional "text me" box on the form. Submitting the form alone does not opt you in. Reply STOP at any time.
