The process of advising on Defined Benefit / Final Salary (DB) pension transfer is complex and specialist. It requires specific adviser qualifications and regulatory authorisations and approvals as well as the adviser and their firm being specifically indemnity insured to carry out such work. An adviser will charge a fee for such advisory work or indeed any pension transfer work.
As I am not that adviser I can’t tell you what that fee might be, however I will be happy to have you chat that over with the adviser that I know who can handle such a process for you. For absolute clarity and transparency, I have absolutely no commercial / financial interest in that advisory process as it is entirely independent from the SSAS set up process and SSAS creation is not predicated on having a pension value to transfer into it.
