Credit transfer?

Hi, my current house is supplied by bulb (great service by the way!) The house is due to be sold this coming friday (20th) and my bulb account is in credit, the house I am moving to (boyfriend) is already with bulb so can the credit from my account be transferred into his? If this is not possible can I recieve s cheque for my credit as the bank account where the direct debit is paid will be closed as soon as possible after the house sale is completed
