Why can't I use my account number to sign in anymore?

We are switching our system to use e-mail addresses as the customer's sign in ID. This is an easier and more secure way to sign in since you do not need to search for your account number or use your personal identification number to sign in.

Why do you need my e-mail address?

The e-mail address you provide will be used as your sign in ID. This is an easier and more secure way to access your account.

Does this mean I will now receive e-mail promotions from National Grid?

We will use the e-mail address you provided as your sign in ID to send you important notifications and communications regarding your account, payments, reminders, and more. If you do not wish to receive notifications at the e-mail address you provided as your sign in ID, please provide a different e-mail address here.
