Apfa senior technical adviser Linda Smith and senior policy adviser Clare Griffiths are leaving the trade body.
Smith is retiring this week after 16 years at Apfa and its predecessors.
Griffiths is also exiting the organisation to join the Bank of England in a banking policy role. Griffiths has been with Apfa since 2012.
Apfa has appointed James Leigh to the role of policy and administration assistant and says it will announce a further appointment to the policy team in the coming weeks.
Apfa director general Chris Hannant says: “Linda has been part of Apfa from the start. She worked for the forerunner the IFAA and has been working for advisers through all the big changes that have occurred over the last 16 years.
“Linda and Clare have been great assets to the association and profession and we will miss their knowledge and experience. We thank them both for the roles they have played.”
