Tilney Bestinvest will be the new name for the business formed by the merger of Bestinvest and Deutsche Bank's UK regional wealth management business.
As the brand was announced today the firm declared its aim to double its Financial Planning team over the next two years.
It follows the announcement in February that the Permira funds, which have invested in Bestinvest, had agreed to acquire Tilney from Deutsche Bank.
Peter Hall, who will be chief executive of Tilney Bestinvest, said: "The outlook for Tilney Bestinvest is very exciting at a time when banks have retrenched from large parts of the advice market and radical reform of pension rules will create a real need for access to high quality, trusted advice.
"We therefore aim to double our Financial Planning team over the next two years to capitalise on this opportunity, as well as to enhance our investment services for financial advisers through our 'Tilney for Intermediaries' division.
"The merger will enable us to help clients across the whole of the UK."
