Switch from British Gas Prepay to Bulb monthly direct debit

My daughter has British Gas supplying gas and electric using pre-payment cards that have to be topped up at a local shop. She wants to switch to Bulb and pay by monthly direct debit. Does she need to have a new meter fitted and wil she lose any pre-paid credit on the current meter?
