Frequently Asked Questions

  • How are the energy networks responding to COVID-19?

    You can read more about how we're responding to COVID-19 on our dedicated webpage.

  • Who is my gas or electricity supplier?

    Your energy supplier is the company which bills you for the energy you use. Your gas and electricity might be supplied by the same company, or you might be supplied by different companies. You can find out who your energy supplier is by looking at a recent bill.

    Your energy supplier is different from your gas or electricity network operator.
