Why NS&I is different#
Most banks now let you change your name in an app. NS&I, the government-backed savings bank behind Premium Bonds, does not: its help pages say you cannot change your name online for security reasons. Your address and contact details are the opposite, changed in a few clicks, so the two jobs are done separately.
Changing your name#
NS&I gives two routes, both on paper:
- Its change of details paper form. Download it from the personal details help page, fill it in and post it. There are separate forms for Premium Bonds, Investment Account (including a version for under-16s) and Children's Bonds.
- A letter. NS&I says you can also write to it, making sure to include your previous name with your previous signature, and your new name with your new signature.
The signatures are the check: NS&I compares the old signature with the one it holds and records the new one against the new name. Sign the letter twice, once as you used to and once as you do now. NS&I's page does not list the deed poll as something to enclose, but keep it ready in case you are asked for evidence, as any savings provider may.
Your address and contact details#
These can be changed in your online account (your profile, then your details), or, if you hold Premium Bonds, through a short online form that needs your holder's number and your previous and new details, without creating an account. NS&I says the same form can change a child's Premium Bonds details. For other accounts and investments, it says you can call or write.
Premium Bonds held for a child#
A child's bonds are managed by the parent or guardian who is the responsible person. If the child's name has changed, the change of details form for Premium Bonds is the route, and the responsible person signs it. Changing a child's name covers the deed poll itself.
Prizes and the name on your bank account#
Prizes and interest are paid into the bank account NS&I holds for you. If that account is in your new name and NS&I still has the old one, a payment can be queried, so change the two in step: the bank first, then NS&I.
