Halifax is expanding its on-line banking service Greenfield.co, which is being launched next Spring.
The move follows what the bank's chief executive Jim Spowart called a “complete review” of the venture.
The service will offer current account transactions, personal loan, insurance, and investment products such as Isas. There are currently no plans to offer mortgages online.
The new proposals will see a doubling of staff to 1,100.
Spowart says: “We think it will be big. Its going to be extremely ambitious, offering a range of products to fit the internet.”
