I’m just another customer but from what you are saying you have a prepayment smart meter. If so then “Your old supplier will swap you over to a credit meter at midnight on the day before your switch. They’ll be able to do this remotely, so they won’t need to enter your property.”
Have you had a switch date from Bulb or do you know for a fact you have switched to Bulb.
