By bank transfer and standing order
You must already have Premium Bonds, and you must know your (or the child’s) holder’s number
Each investment by bank transfer or standing order must be at least £25 and each investment must be in whole pounds.
Give the following details to your bank and tell them how much to transfer and how often. You’ll normally be able to do
this online, by phone or in a branch, depending on your bank.
|| You must enter your Premium Bonds holder’s number (not your NS&I number) as the reference.
You can find your holder’s number on your Bond record or by logging into our online service.
Make sure you enter your holder's number correctly without any hyphens, spaces or full stops.
Don't add any other information in the reference field apart from your holder's number.
