Leeds has enrolled 30 of its mortgage advisers and branch managers with the Society of Mortgage Professionals.
Richard Fox, chief executive officer, Society of Mortgage Professionals, said: "Leeds is the first building society to make public its commitment to professionalism in this way. Its customers and staff - indeed the whole market - will be the beneficiaries. We look forward to others following in their footsteps."
Katherine Tong, of Leeds Building Society, commented: "We decided to take this step in recognition of the tremendous commitment to professionalism that our branch managers and mortgage advisers have already shown in observing and fulfilling the rigorous requirements of our Training and Competence programme.
"It is essential to us that our customers are served by individuals at the forefront of their profession. Whilst this is in part a congratulatory gesture, we also acknowledge that the continuing professional development (CPD) will help us to encourage and maintain the highest standards of competency and integrity from our representatives."
