Still on 100 amps? Get a real number from a licensed electrician.
Panel upgrades, 200-amp service, EV chargers and standby generators. One licensed Connecticut contractor calls you — your request is never sold to a list.
What Fairfield County homeowners are upgrading
Planning ranges from dated 2025–2026 sources. Not quotes — a licensed electrician prices your job after seeing it.
200-amp panel upgrade
Like-for-like swap or 100A→200A with new meter socket, mast and grounding. CT contractor ranges: about $1,800–$4,500.
What drives the price →Service upgrade
The utility side: weatherhead, service cable, meter, disconnect. Eversource and UI each have a cut-and-reconnect process your electrician files for.
How the utility step works →Level 2 EV charger
Hardwired 40–60A circuit, GFCI-protected per NEC 625. National installed range $700–$2,000 before any panel work.
EV charger guide + 2026 utility incentives →Standby generator
22–26 kW units with automatic transfer switch. Gas meter sizing and a 30-day utility form come first in most of Fairfield County.

Three things worth knowing in 2026.
The federal panel credit is gone
§25C's $600 panel credit ended for work placed in service after 12/31/2025 (P.L. 119-21). Anyone still advertising it is out of date.
What's still available →Permits are cheap; skipping one isn't
Trumbull, Stratford and Monroe charge about $5 per $100 on the first $1,000 then $10 per $1,000; Stamford $13 per $1,000. Unpermitted panel work shows up at sale and on insurance.
Town-by-town fees →Some panels are a replace-now decision
Federal Pacific Stab-Lok and Zinsco panels have documented breaker-trip failure rates, and some insurers won't write a policy with one in the house.
Check your panel brand →Questions homeowners ask
Is this a contractor or a lead-selling site?
Neither the way you'd expect. ElectricalPanelUpgrade.net is a network property run by AeqR. Your request goes to one licensed Connecticut electrical contractor assigned to this area — not auctioned to five companies. The current provider is named at the bottom of every page.
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 run roughly $60–$300 depending on the town — see the town-by-town permit guide.
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. Details in the 2026 rebates guide.
What happens after I submit?
You get a confirmation page. A licensed electrician from the assigned provider calls the number you gave to ask a few questions and set up a site visit. No estimate is final until they have seen 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.
