Change the account holder to another resident

Hi,
We are a flatshare and I am about to move out soon. Can I change the account holder of this account or do I have to resign and then my flatmate subscribes again to a separate account? If yes, what are the steps?

@daniel30 there are a few ways to skin this cat, but in my opinion the best is to use the move-out wizard at https://account.bulb.co.uk/dashboard/move-home
