The power to settle financial complaints.

1 March 2010
According to research published by the European Commission [586-page report in PDF format] on ombudsman schemes in Europe:
There is a network of financial ombudsmen and consumer-complaints organisations across Europe. This network – which includes the UK's Financial Ombudsman Service – is called FIN-NET.
FIN-NET's job is to help synchronise communications when a consumer living in one European country has a complaint against a financial services business based in a different European country.
FIN-NET has a website to help consumers check if there is an ombudsman scheme (or other complaints-handling body) dealing with financial complaints in a particular European country.
