The founding director will be involved in product development across the different areas.
Mirfin said: “This new role is about me standing back and looking at each area of the business on its own merit.
“I will also be able to engage with people and the media on far wider issues.”
Mirfin has been with the business since its origination in 1998. At the time it employed 12 staff, but now the group employs more than 300.
Colin Taylor, chief executive of KR Group, said: “With over 25 years’ experience as a mortgage, equity release, and retirement expert, Dean’s new role is central to the next stage in the growth story at Key where technical knowledge and wider reaching advice will play a major role.”
Key said they created the role partly as a response to the wider reaching options that have come about from pensions freedoms.
Mirfin added: “Pension freedoms have created massive opportunities for retirement savers but people need guiding through the improved options available, needing a wider perspective which must also include the home as well as effective estate planning.
“Key is ideally placed to help savers understand their options and to ensure they maximise retirement income.”
