Welcome to NS&I

This website is a great place to find out more about us, the products we offer as well as finding answers to questions you may have.

If you would rather just ask us a question, you’ll find our contact details at the bottom of each page.

Managing your account

The easiest way to manage your money and personal information is to use our online service. You’ll need to register to use this service (you only need to do this once), when registered you’ll be able to manage your money 24/7 (online and over the phone).

If you have money in our Investment Account you’ll have to manage this by post, unless you move your money into one of our other products.

If you’ve already registered for our online and phone service since turning 16 you don’t need to do it again, just
log in.
