Seven steps to switch in Connecticut
- Find what you pay now. Your bill shows the price you pay for standard service. Write down that price and the date it will next change. It is the standard service rate on your utility bill.
- Check that you can choose. Look at your bill. If your power comes from a city utility or a cooperative, it may sit outside the choice program, so confirm before you shop.
- Compare on the official site. Start with EnergizeCT, which is run for consumers. Look at the price type, the term and the fees, not only the headline rate.
- Get the terms in writing. Ask for the price per kWh, whether it is fixed or variable, the term, every monthly fee, the early termination fee and what the price becomes at renewal.
- Sign up with the supplier. You enroll with the supplier, not with your utility. Keep the contract and any confirmation, and note how long you have to cancel.
- Watch for the start date and your first bills. Your utility handles the change. Expect a notice, and check that the supplier name, the price and the start date match what you were told.
- Mark the end of the term. Put the renewal date in your calendar. Many plans change price at the end of the term unless you choose again.
What we checked for Connecticut
These points come from the regulator or its official shopping site, or from the supplier disclosure language that its rules require. Each names where it was read.
- Connecticut law gives you a three-day rescission period after you sign up with a supplier. Source: EnergizeCT supplier offer pages.
- A supplier must wait three days before sending your enrollment to the utility, and it must submit the enrollment within seven business days of your request. Source: EnergizeCT supplier offer pages.
- At the end of a contract, you must contact the supplier to cancel or negotiate, enroll with a new supplier, or contact the utility to return to standard service. Source: EnergizeCT supplier offer pages.

What to confirm before you sign in Connecticut
We could not confirm these points from an official page, so we do not state a number for them. Ask the supplier, read the contract and check with the Connecticut Public Utilities Regulatory Authority.
- Any early termination fee and how a renewal is priced
- The current standard service rate for your utility
- The date of your next default price change, so you compare offers against the right number
What a small price gap is worth
The average Connecticut home used 704 kWh a month in 2025, or about 8,452 kWh a year. At that use, every 1 cent per kWh of difference between an offer and the standard service rate on your utility bill changes the yearly bill by about $85. A gap of 2 cents is about $169 a year, and 0.5 cents is about $42.
Those numbers shrink or grow with your own use. A monthly fee of $5 adds $60 a year, which can erase a small price gap. Run your own numbers with the electricity bill calculator, and compare fixed and variable plans with the fixed vs variable rate calculator.

Who still delivers your power
Switching does not change the company that owns the lines and the meter. In Connecticut, the largest investor-owned utilities by residential customers in 2025 were:
| Utility | Type | Homes served |
|---|---|---|
| Eversource Connecticut | Investor-owned | 1,193,581 |
| United Illuminating (UI) | Investor-owned | 314,909 |
Source: U.S. Energy Information Administration, Form EIA-861 (final 2025 data), residential customers. Call your utility for outages whichever supplier you use.
If something goes wrong
Keep your contract, your confirmation and any call notes. If you think you were switched without permission, tell your utility and your regulator right away. The Connecticut Public Utilities Regulatory Authority takes complaints about suppliers.
Be wary of anyone who says they are from your utility and says you must switch, who asks for your account number before you have seen a contract, or who will not give you the price and fees in writing.

Can I cancel after I sign in Connecticut?
Connecticut law gives you a three-day rescission period after you sign up with a supplier.
Do I still get a bill from my utility?
In most cases yes, and your utility still delivers the power, owns the meter and restores service after an outage. Some suppliers send their own bill, so read the contract.
Is a supplier cheaper than standard service?
Sometimes. It can also cost more. Compare the offer with the standard service rate on your utility bill over a full year, and include fees and the renewal price.
