  The more details you can give when you write to us, the more quickly we can deal with your request.

  Your personal details: name; address; date of birth. If you haven’t told us about a house move or a change in your marital status or name, please also include your previous name and address.

  Your reference numbers. Any or all of these: your NS&I number, holder’s or customer number, account number, Bond numbers, or Certificate numbers, if you know them. You’ll find these numbers on your Bond records, certificates of investment or any other letters from us.

  Details of your accounts or investments: type of investment (e.g. Premium Bonds); approximate start date; and amount, if you know them.

  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:

  www.financial-ombudsman.org.uk

  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.customer.feedback@nsandi.com
