Nonetheless the FCA has said it considers this issue to be important and has asked for specific feedback on this.
This came as the Fos revealed it has received 15,000 complaints involving pensions since the introduction of pension freedoms in 2015, with just 300 of these relating to defined benefit transfers.
Caroline Wayman, chief ombudsman at the Fos, said: "Most financial advisers I meet – and indeed most financial advisers – haven’t ever had a complaint. As long as advisers continue to treat their customers fairly, it’s likely to stay that way.
"As ever, the challenge for advisers isn’t just to know the rules, but to apply them to real lives – understanding where people are coming from, their hopes for the future, and what really matters to them. We’ll continue to share our insights from the complaints which we see."
The FCA declined to comment.
