FTB - Want to switch from Prepay to Credit Plan

SKM89

Hi everyone! 
I have just bought my first home and the property is currently on Dual Fuel via prepayment meters with Bulb. I want to chase this over to a monthly DD plan. I can find cheaper deals elsewhere but my question is, do I need to ask Bulb to change the system from Prepay to Credit BEFORE switching, or if I switch, will my new supplier automatically install and change the system over? 

So sorry if this seems like a simple question but first time I've done this! 

Thanks in advance for any help

You need to read any papers you signed that mention the supply of gas and electricity.
If you have signed nothing then you are free to switch to any supplier that will take you on.

Thank you - but with regards to switching from prepay to a credit meter, do I need to do that with the current supplier of the property or with a new supplier?
