  • physical problems to do with the supply of energy to a home or small business (e.g. power cuts).

Who can complain?

You can use the service if you are a domestic or a small business customer and you are:

  • complaining about a company which provides energy to your home and which is a member of our service (a ‘member company’); or

  • having problems resulting from changing your gas or electricity supply to or from a member company; or
  • representing a customer who meets one of the conditions above and have the customer’s permission, in writing, to make the complaint.

You must have been in one of these categories when the problem you’re complaining about began.
