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. Your network operator maintains and operates the wires and pipes which carry electricity and gas from power stations and gas terminals, across the country and into your home. You can read more about how the energy networks operate.
If you don't have a recent energy bill, you can enter your postcode above and contact your local network operator who will be able to tell you who your electricity supplier is. You can find out who your gas supplier is by using the find my supplier website (just so you know, this website isn't operated by us).
