My old supplier wouldn’t let me move to bulb because of debt I thought I’d be able to and continue paying of the debt with bulb
Are you on normal meters or prepayment meters? If normal “credit” meters then you’ll need to clear your debt before switching. If on prepayment you should be able to switch if you owe less than £500.
