The current chance of each one pound unit winning is last time I looked 34,000 to 1. So if you had £34000 of premium bonds statistically you would be likely to win one prize each month. The vast majority of the prizes are the £25 prize. so statistically with average luck you could expect to win £300 a year in prizes.
The recent NS&I rate increase reduced the odds to 1 in 24,000 and our returns off maximum holdings, last month, returned us £175 which is almost twice what we were averaging over the previous 12 months. I'm hoping they continue to raise the rates on Premium Bonds and would also welcome an increase in the number you can hold
