Your Energy broker will also need to support you in the agreements and contracts that you sign concerning the new suppliers arrangement with your payment of bills. Your new supplier will take care of the changes, so you should not worry yourself over the processes involved. You will only give then your bill, and they will work on the switching to ensure that the next scheduled meter reading will be done by them. Unless you have signed a contract to start at a later date, you should get the next bill from your new electricity supplier. This process normally takes a period of thirty days or less for the switching to be settled completely.
