I signed up To smart pay as you go after many years being on this type of prepayment and it worked well for me. No bills or debt which I really liked. After the change over date I was placed into credit mode until smart meters installed this was ok for and I would money aside for the final credit bill after meters installed. Meters were installed well over a month after change over and I expected and signed up for smart pay as u go. smart meters installed were not pre payment method Meyer’s and after a few weeks of trying to get what I signed up for in a contract was told oh no we can’t change you to what you did infact believe you was getting because we don’t do that Ian your area. I am now on a credit smart deal that was not requested or indeed promised. I was totally missold this utility and left with a service I did ask for want or even agree to. I was lied to over the phone, promised call backs that I never received and still now over two months later in the dark over what can be done. I have since cancelled all my home insurance boiler etc after years of being a loyal customer and await a resolution for gas electric supply but their ignorance of this case will probably mean I need to switch suppliers again. Buyer beware and and think twice before you sign up to this company that lied and missold me this utility.
