We've been resolving disputes between financial businesses and their customers since 2001.

The information on this page is for consumers who have a complaint about a CMC.

If you’re a CMC, you’ll find our information for CMC businesses useful. We also have separate guidance for financial services businesses on the financial ombudsman service website   and for small businesses (SMEs) that want to make a complaint.
