Incumbent managing director Dominic Taddei will take on the role of chief executive, with Claire Taddei appointed as chief financial officer.
Gaughan previously held the role of national sales director at Countrywide Mortgage Services, where he led a UK-wide team of over 500 advisers.
Prior to that, he held a senior role at Slater Hogg and was also head of Halifax for Intermediaries.
Gaughan said: “Since joining, I have been impressed with the ambition and customer-focused attitude shown by every member of the team. We are leading the way with our technical innovation and operational processes, and I can’t wait to help drive the business forward alongside a talented senior team.”
Taddei added: “As we look forward to 2022 and the next chapter in our business, I felt the time was right to bring some fresh operational ideas.
“The changes will allow Claire and I the time to focus on further strategic opportunities, whilst continuing to work closely with Kevin and the wider management team. I wish Kevin all the best in his new role.”
