Premium Bond prizes worth more than £95 million – and RISING - still yet to be claimed - how to check
They amount to £95.3 million in prize money and date back as far as the Fifties.
As of December 2024, the top eight prizes to go unclaimed were each worth £100,000.
In total there were 2,530,260 unclaimed Premium Bonds prizes worth £95,312,325 waiting to be claimed in March 2025, according to NS&I data.
This is up by £3 million in just three months since December 2024.
And it's an increase of £15 million since NimbleFins first reported the figures in September 2023.
NS&I hands out thousands of prizes every month ranging from £25 to £1 million.
Although bondholders are usually contacted when they win, many people forget to change their details when they move house or switch personal details. A letter can get lost in the post or emails end up in junk folders. They then may also forget to check their numbers every month, which can be done online or on the NS&I app.
Some people may have forgotten about their bonds entirely, with 13 unclaimed prizes of an average of £27 dating back to the Fifties.
That £27 would now be worth up to £1,300 in today's money, according to this inflation calculator.

In March 2025, there were two £1 million winners - from Cumbria and Cleveland. The Cleveland winner had only invested £100 in May 2023.
NimbleFins previously reported NS&I has raised the chances of winning a Premium Bond prize to its highest level in 15 years. (Read here if they are worth buying)
But the investment is not worth it if you forget about them.
How to check if you've won Premium Bond prize
The good news is there is no deadline to claim a Premium Bond prize and NS&I keep hold of the cash until it’s claimed.
As of September 2023, there were 2,300,822 unclaimed Premium Bond prizes worth £80,254,250. In March 2025, there were 2,530,260 unclaimed prizes worth £95,312,325.
The best way to avoid missing out on a prize is to have winnings automatically paid into your bank account or reinvested in more bonds, NS&I says.
You can do this online.
But if you want to check if you have unclaimed winnings, the quickest way to do this is to use the NS&I prize checker online or on its app.
You can also write to NS&I to ask for your prize history. You'll need to tell them your name, address, date of birth, NS&I number or Premium Bonds holder's number. The address is: NS&I, Sunderland SR43 2SB. Note, its Blackpool and Glasgow addresses are no longer in use.
