Premium Bonds Get a Boost, But Don't Bet the Farm Just Yet The UK's National Savings and Investments (NS&I) has increased the premium bond prize fund rate to 4. 35% from September onwards.
The move raises the number of prizes available by 308,000 compared to this month's draw, with a total prize pot increasing by around £63m to £497m.
However, the odds of winning remain low at approximately 21,000 1 per £1 bond number. To put that into perspective, you're more likely to win the lottery than snag one of these prizes.
