Moving to Delaware: utilities and your first-month checklist
Which company serves your new address depends on where in Delaware it is. Each link below goes to that company's own page for starting service. Start it two to three weeks ahead, from the day you get the keys.

Choosing a supplier
Delaware lets some customers choose who supplies their electricity. The wires and pipes stay with the utility. Compare on the state's own page before signing anything a door-to-door seller offers: official shopping page.
Help with the bills
If deposits or bills are a stretch, Delaware runs energy assistance: official assistance page. Ask the utility about deposit waivers too; many waive the deposit with a good payment letter from your old company.
Problems with a utility
The Delaware Public Service Commission regulates utilities in Delaware and takes complaints.

- Register to vote: Routes you to the official registration for the new state.
- Medicaid, if you have it: Medicaid doesn't move with you. You apply again in the new state.
- Health insurance: A permanent move can open a special enrollment period.
- Social Security: Change your address once here; Medicare gets it from Social Security.
