Resolving disputes

The Financial Ombudsman Service (FOS) provides consumers with a free, independent service for resolving disputes with financial firms.

We do our utmost to resolve complaints directly, saving our customers the trouble of appealing to the ombudsman. But when a customer makes a complaint and we can't reach an agreement, the FOS can be asked to make an independent assessment.

The lower the percentage of such complaints upheld by the FOS, the better a firm's complaints-handling.

Here are the latest figures published on 6 September 2016 by the FOS for Nationwide (Period January - June 2016).

  • Overall figures
  • Banking
  • Home
  • PPI
  • Insurance
  • Retirement

FOS figures show no data in Retirement Finance category for January  – June 2016 for Nationwide. This occurs because either there were no cases or there were fewer than 30 cases and so the percentages would not be statistically meaningful.
