Frequently asked questions

In this section you’ll find the answers to the most frequent questions asked by advisers about NS&I

  • What is a Letter of Authority?

    A Letter of Authority (LoA) is a document for customers to give written authority to NS&I to provide information on their NS&I accounts with their specified financial advice firm. NS&I will only accept LoAs on its own template, and this is available on the NS&I Adviser Centre (nsandi-adviser.com). In most cases, the advice firm will complete and send in the LoA to NS&I on behalf of the customer, with the customer just needing to sign it.

  • What is a Terms of Business agreement?

    Our Terms of Business agreement (ToB) is a document which forms the legal relationship between NS&I and a financial advice firm. This details information which ensures and protects the relationship between NS&I, the financial advice firm and our mutual customers.

  • What is the difference between RPI and CPI (the indexes used for Index-linked Savings Certificates)?

    Both the Consumer Prices Index (CPI) and the Retail Prices Index (RPI) measure inflation. Each aims to measure the changes in the cost of buying a 'basket' of products and services, but they cover different items and there are differences in the formulas used.

    To find out more about CPI and RPI, visit the Office for National Statistics website at ons.gov.uk and search CPI All Items Index or RPI All Items Index.

  • What is the role of NS&I?

    As an Executive Agency of the Chancellor of the Exchequer, our role is to help reduce the cost to the taxpayer of government borrowing by providing the Government with cost-effective finance compared with raising funds on the wholesale market. We do this by offering savings and investments to personal savers and investors.

  • When accessing joint accounts for my customer online the Authority field is blank in some cases. Why is this?

    The Authority field will only be populated if the client is registered for the online and phone service. If they are an unregistered customer, then the Authority field will remain blank until they become registered. This will not affect how you access and view their NS&I holdings.
