Welcome to NS&I
We've been waiting to meet you
Come on in to discover who we are and what we do here. You might have some questions, so we've got some answers at the ready. If you want to ask us anything directly, our contact details are always at the bottom of every page.
Looking after your account
The easiest way to manage your money and personal info is with our online service.
You’ll need to complete a registration form and send it to us first. This is because we need someone to witness your signature as proof of identity.
Once we have this, you’ll be able to manage your accounts online (except for Investment Account, which can only be managed by post).
Please ask a witness (anyone over 18, but not a family member) to write the following in a covering letter, which they’ll need to sign and date: "I certify that (your name) signed the enclosed form in my presence and that I am not a member of the same family".
We'll also need your witness to print their name, address and occupation in the same letter. Please send the letter to us with the completed form.
