The Ombudsman is where you take your complaint if you have already complained to a financial firm but they haven’t resolved the issue to your satisfaction.

Every six months it publishes data on which individual financial firms have attracted the most complaints.

The latest results show complaints have dropped across the board, with 191,129 new cases in the first half of this year compared to 248,801 in the second half of 2013.
