How do you start or transfer ComEd service when you move?

Start with the day you get your keys or your lease begins. Work backward from it. The planner below turns that one date into a list of dates you can follow. It also saves them as reminders. To begin, open ComEd's Start My Service form, which is ComEd's own page, or use the phone number above. The link ends in "flowTypw", a misspelling in ComEd's own address; it works as written.

1. Pick your power-on dayUse your key day or lease start. Do not pick the day before you can get inside
2. Apply at least 7 days aheadOnline, or by phone at 1-800-334-7661. Our rule of thumb, not a legal rule
3. ComEd answers within 2 business daysThe state rule counts from the day ComEd has all your information
4. Power turns on within 4 daysUnless you ask for a later day, which is allowed
5. Check the day before you moveMake sure the request shows the right day and someone can reach the meter

This is a guide built on public rules. It is not a quote or a bill, and ComEd decides your deposit and your dates.

The state rule lists what a utility may ask for. You do not need paper copies for most of it. Have the details ready before you start the form.

• Your service address and where to send your bills.
• A phone number, and how you want ComEd to contact you. An email is optional.
• A landlord contact, if you rent. This is optional.
• Two kinds of ID. One must be a government photo ID. The other is your pick from a list that includes a second photo ID, a Social Security number, a driver's license number, a birth certificate, a student ID, or bank information.
• Any old ComEd debt paid. If you owe a past bill at ComEd, it must be paid or put on a payment plan first.

ComEd's form says it cannot finish a request when a past balance is unpaid. It also says business accounts cannot start online. Business owners call 1-877-426-6331, the business line on ComEd's contact page.

Illinois rules define a transfer as ending service at one address and starting it at another, with the same utility, within 14 days. That helps you. You are not treated like a stranger, and you can keep your bill history and your plan choices together.

• New to ComEd: you are a new customer. Follow the steps above.
• Moving inside ComEd territory: tell ComEd both addresses, the stop day and the start day. Keep the gap under 14 days.
• Leaving ComEd territory: ask ComEd for a final read and stop the old account. The new utility starts its own account.

A deposit is not part of every start. The state rule allows one for an applicant only in these cases:

If a deposit applies, there are limits. The most ComEd can ask for a home is one-sixth of a year of estimated charges, which is about two months of bills. ComEd must send a notice first, within 45 days of your approval, and cannot bill a deposit before it. ComEd may split the deposit into three parts, a third on each of your first three bills.

Your deposit earns interest at a rate the state sets each year. You get it back on its own after 12 months in a row with fewer than 4 late payments and no disconnection for nonpayment.

Your bill has two parts. ComEd delivers the power and charges a fee for that. The supply part is the energy itself. If you pick no supplier, ComEd charges its price to compare for supply.

That price is 10.103¢ per kWh now. It has been in effect since October 1, 2026 and runs through May 31, 2027. At 700 kWh a month, the supply part is about the price times 700. The planner does the math with your number and shows it. Delivery, taxes and fees are added on top, so your bill will be higher.

Your first bill may also cover a part month. Ask ComEd for the read date on your account.

Both are legal and safe. Your power does not change either way. ComEd still delivers it and fixes outages.

On October 25, 2026, we counted 44 offers from 16 suppliers. Of the 41 fixed-price offers, 3 were priced below ComEd's price to compare. The cheapest fixed offer of 12 months or longer was 10.34¢. The median fixed offer was 11.79¢.

Our rule: stay on ComEd supply for the first month or two if you are new. Then compare. Pick a supplier only if its price is clearly lower after any monthly fee, and you can leave without a big exit fee. Put the supplier's price and fee in the planner to see the monthly difference.

See the price to compare in Illinois and our list of Illinois suppliers. If ComEd's price will change soon, the planner shows the date and sets a reminder for two weeks before.

These are the reasons we can back with ComEd's form and the Illinois rules. If none fits, call 1-800-334-7661 and ask which one stopped your request.

Call ComEd at 1-800-334-7661 the same day. ComEd says its representatives take calls 24 hours a day, 7 days a week. Say your address, the day you asked for, and the date of your request. Illinois rules give a credit when a utility is late by 2 days or more. Ask about it. If ComEd does not fix it, you can file a complaint with the Illinois Commerce Commission.

Once you are in, set up the tools for an outage. ComEd says you can report one by text message or mobile app, any hour, or by calling 1-800-334-7661. Its online self-service page also links to outage alert sign-up. Sign up on day one, not during the first storm.
