Speaking to MoneyWeek, a spokesperson for NS&I said: “Premium Bonds prize winners receive notifications of their winnings if they have registered their contact details.
“However, sometimes customers relocate or forget to update their details with NS&I. This can lead to unclaimed prizes, especially for those who opt to receive their prizes via cheque rather than bank transfer.”
The spokesperson explained unclaimed prizes gradually accumulate every month and usually belong to Bond holders who "have not registered their details or have moved without telling us and their cheques are being returned".
They added: “We want to reunite people with their prizes, so this is a timely reminder that even for small holdings that may have been held for many years, it is worth registering your details with NS&I.”
