Tilney has hired Andy Grant to become the company's head of financial planning.
He will be tasked with growing Tilney's financial planning business, which is currently made up of 208 financial planners in 30 offices around the UK.
Chris Woodhouse, chief executive of Tilney, said: "He brings extensive experience in managing teams, business integrations, change management and driving growth and joins at a really exciting time for the business as we embark on our next phase of growth and development.
"Tilney is in great shape having invested heavily in both new technology and building our brand while also recently reporting a record year for revenues, gross new business and profitability."
He said Mr Grant would lead what is already a sizeable, UK-wide team of exceptionally high-calibre financial planners and he will play a pivotal role in helping us build our financial planning business further, including through new hires and potential acquisitions.
Mr Grant joined Tilney from the British Business Bank where he has served as chief operating officer.
Before this he was chief operating officer of Royal London where he helped prepare the provider for growth and execution of a new strategy.
At Royal London Mr Grant developed and led the plans to reposition the business under the Royal London brand across long-term savings, protection, wrap platform and asset management divisions, as well as the launch of a digital direct-to-consumer business and the integration of the insurance and asset management businesses acquired from the Co-op.
