As far as I'm concerned, the only qualification someone needs to give financial advice is that they give good financial advice.
That excludes a lot of "professional" financial advisers who sometimes recommend expensive investments, purely because they get kickbacks. I recall a good friend who moved all his pensions after advice from a "financial advisor". I queried the fees and was told it's just over 1% per annum. I queried if that included both the platform management fee AND the fee for the funds. I encouraged my friend to check the documentation thoroughly. He was livid when he discovered the total of fund fees and platform fees came to about 2.4% per year. Bear in mind he was over 20 years from retirement, so about 40% of his initial investment would go in fees over that period.
He moved his pension again without the hinderance of a financial advisor.
