For the April draw, two new millionaires were made overnight in South Yorkshire and Hertfordshire. Meanwhile five people won £100,000 each from Premium Bonds they bought in the first months of 2025.
The Premium Bonds jackpot prize winners are notified by Agent Million. Other winners are told via post or email – meaning if you haven't updated your contact details you might not know you've won a prize.
All bondholders will be able to check whether they won any prizes from Wednesday 2 April.
You will only be informed of any winnings if your account information is up-to-date. If not, you could be one of the millions sitting on an unclaimed Premium Bonds prize worth up to £100,000.
If you moved abroad after buying some Premium Bonds then you are still eligible to claim prizes, so it’s worth checking for unclaimed prizes or lost bonds even if you have left the UK.
