Legal & General's director of individual wealth products, Andy McKinnon, said: "The choice and flexibility of the pension means it can adapt over time to a customer's changing situation, without the need to transfer to another plan."
He added that the company's "product expertise, excellent service and distribution strength" would provide advisers with a chance to "choose from a broader range of competitively priced funds".
Legal & General also recently launched a new tracker mortgage through its Mortgage Club initiative.
