Louisa Sedgwick will take up the role at the Yorkshire-based society following a period as a freelance consultant for financial services institutions.
Prior to this Sedgwick spent 19 years in the intermediary sales division at Bradford & Bingley and has also advised other suppliers on their relationship management.
Sedgwick will be tasked with appointing account managers to the mutual organisation.
“I am delighted to welcome Louisa to Leeds Building Society’s intermediary team,” said Martin Richardson, Leeds Building Society’s business development general manager.
“Her experience working with key accounts and third party suppliers, as well as her extensive industry contacts, will complement and strengthen our existing team at a time when our mortgage lending through intermediaries is continuing to grow.
“One of Louisa’s first tasks will be to commence recruitment of additional account managers, which will happen in the next few months.”
Sedgwick said: “After more than 20 years in financial services, I am enormously excited at the opportunity to be joining Leeds Building Society as it enters a new era of intermediary partnerships.”
