Wow, check out that £100,000 win on £10's worth of bonds!

Bought in 1965! Wonder if it'll be claimed?!

Assuming NS&I have been kept abreast of any changes of address, wouldn't they inform the winner by post anyway?

Edit: In fact, isn't the ball firmly in NS&I's court with respect to notifying winners whatever the size of the prize? Or are holders expected to keep a constant look-out?

Mm, just checked my PB's and won £150 this month..........wander when I get the cheque/s? (Low return on 30K investment, but fun)

Removed incorrect info.

So, if someone wins £50, what happens?

Is it NS&I's responsibility to try to contact the winner, or the winner's to keep a look out?

Sorry, it seems I was wrong in that last post. From the T&Cs:

"If you're a winner we will write to you, unless you win one of the £1 million jackpots when our representative will visit you personally with the good news (always ask for identification). So it's vital that you tell us of any change of name or address."

"Everyone is contacted automatically when they win a prize. But there are occasions when people have moved and not told us. If you win a prize and we can't get in touch with you, we will hold on to the prize until you contact us. Don't worry, there's no time limit for claims."

In the second week of each month they send you your prize or prizes in the form of a cheque , even if it's £50 , OR if you had ticked the option { this is changeable } when purchasing the bonds your prize is reinvested as more bonds { unless you have the max of 30k } to go in the next draw .

Current odds are 21,000-1 per £1 unit , the prize pool has a current rate of 3.60% NET this is poor odds , although possibly worth it for 40% tax payers .
