How to change your card on file for ComEd

Last reviewed September 14, 2026

ComEd powers Chicago and northern Illinois — a steady monthly charge. You keep every card you carry — this just makes sure ComEd renews on the one that earns the most.

Service area: Northern Illinois & Chicago

Where to update it

In your ComEd account: My Account → Billing & Payments → AutoPay.

Step by step

Sign in at comed.com or the app.
Open Billing & Payments, then AutoPay.
Add the card Pikt recommends.
Confirm so the next bill uses it.

Heads up: Many utilities charge a convenience fee for card payments (often $1.50–$3) — check it doesn't outweigh the rewards before switching from a bank transfer.

Make your recurring payments count.

Create your Pikt account to personalize recommendations to the cards you carry and the reward preferences you set. In Subscriptions, compare those cards for recurring bills before you change a card on file. Pikt Checkout brings the same estimate to online checkout and names the card likely to earn the most. You choose the card and pay with your own card. No credit card required to sign up for beta.
