Who is my supplier?

If you have moved home, or have not looked at your bills in a while, then you may not know who your gas and electricity supplier is. Here is what you should do to find out who supplies your property, and what you should do to switch.

Find out who supplies the property: first of all, look for literature from the supplier in the post - if you have just moved in, chances are that your supplier would have sent a number of letters already with instructions on what to do to set yourself up with them. If you have been in the property for a while, then you should have been receiving bills.

Sometimes energy companies change name, too! So have a look at our handy table below - if you recognise any of the names on the left, then the current name of your supplier is on the right:

If the names in the table above do not ring a bell, then you can call the electricity distribution company in your area (see the numbers below for help) or the gas infrastructure company National Grid to find out who your gas supplier is. If you give them your address, they will tell you who your supplier is

These companies can also help if your property is currently disconnected from the grid, if the property is not yet connected or if you need to report an emergency.
