If we can't resolve a complaint to your satisfaction, you may be able to refer it to the Financial Ombudsman Service, which is free and independent service for resolving disputes:
Alternatively, if you applied for your NS&I account or investment online, you can submit your complaint via the Online Dispute Resolution (ODR) platform. The ODR platform was set up by the European Commission to help consumers resolve disputes about goods and services bought online from a company within the European Union. The ODR platform will redirect your complaint to the Financial Ombudsman Service (FOS) in the UK, so you may prefer to contact FOS directly.
To use the ODR platform you will need to quote our email address: NS&I.email@example.com
We have an ethos of fairness and transparency. In view of this, and in line with other financial services organisations, we are publishing our complaints data on our corporate website.
