The FOS says complaints involving advice on transferring out of Serps fell by a third.
It says: “A significant number of Serps’ complaints had been submitted in the previous year by a small handful of claim management companies. Most of those cases had no realistic chance of success, given the circumstances involved and the fact that the claim management companies had done little work themselves to look at the actual merits of the individual cases. The claim management companies involved in this area are no longer in operation.”
A quarter of all complaints were referred to the FOS by commercial claim management companies on behalf of consumers, a 40 per cent increase.
