change to monthly direct debit

i am in the process of joining bulb, i have prepayment meters with another provider and want to join bulb and pay a monthly direct debit - i don’t want to use the prepayment meters.
i read the help page “Can I switch to Bulb with a prepayment meter?” - but this doesn’t answer my question.

i have received a welcome email from bulb saying they will sent out my prepayment card in 2 weeks - but i would like to know how to start off with buld paying direct debit.

Can anyone help with this please?
any assistance appreciated,
many thanks
