Nick Cann, chief executive of the Institute of Financial Planning, has said Level 4 will not be sufficient to deliver Financial Planning to clients.
At the final day of the IFP Conference, which is held at Celtic Manor Resort in Wales, Mr Cann said Level 4 was not enough.
Level 4 is the minimum requirement by the Financial Services Authority for advising clients post-RDR.
Mr Cann said: "Level 4 won't be enough to deliver quality Financial Planning. Creating a robust Financial Planning business takes time and having the right people and support.

"It's not just about examinations, it's about having the right skills and being able to communicate that with clients and enabling them to take action."
Next year, he said, would be a "very different year for the financial services industry" and Mr Cann said he hoped the IFP would see more Financial Planners taking the CFP exam and then progressing to Accredited Financial Planning Firm status.
The role of the IFP, he said, would be encouraging these advisers to take the next step towards CFP and embrace the Paraplanning profession.
