Before you start linking Loop to your smart meter

In order to prove that you live at the address being registered you'll need a payment card that’s registered to the address where the smart meter is or the In Home Display that was provided when your smart meter was installed. You choose which method to use. If you use a payment card, no payment is taken. It is important for us to be clear about that. 

If you don’t have a payment card registered at the address or if authentication is unsuccessful, you’ll need to have access to your smart meter's In-Home Display: this is the small electronic display you were given when the smart meter was installed. Don't worry if your display doesn't work, you'll be able to register your meter by entering a code printed on the side.
