NS&I has increased the premium bonds prize fund rate for the second time in recent months, meaning September’s draw will include an estimated 308,000 more prizes than August’s. The change affects all 22 million people who hold the government-backed savings bonds, improving the overall odds of winning without altering how the draw itself works.
What has changed for premium bonds savers?
NS&I has confirmed it is lifting the prize fund rate, the figure used to calculate how much money is set aside each month for prizes across all bond holders. As a direct result, the total number of prizes awarded in the September draw is expected to rise sharply compared with the previous month, giving savers a statistically better chance of a payout, even though individual odds per £1 bond unit remain guided by the same prize structure used each month.
The increase applies automatically to eligible bonds already held, meaning savers do not need to take any action to benefit from the improved odds. NS&I periodically adjusts the rate in response to competition in the wider savings market and its own funding targets set by the Treasury.
Why does NS&I keep adjusting the prize fund rate?
NS&I regularly reviews its rates, including the premium bonds prize fund, to stay competitive with other savings products and to manage how much money it needs to attract from savers on behalf of the government. When interest rates or savings market conditions shift, NS&I can raise or lower the prize fund rate, which in turn changes both the average return and the number of prizes distributed each month.
Savers now have a better chance of winning than in previous months, the savings bank said.
What does this mean for the 22 million bond holders?
For the millions of people holding premium bonds, the practical effect is a higher probability of scooping a prize in the September draw, ranging from small amounts up to the two £1 million jackpots awarded monthly. While premium bonds pay no guaranteed interest, this adjustment effectively increases the pool of money returned to savers through prizes rather than fixed interest payments.
Financial commentators note that while the change is a modest positive for holders, premium bonds remain a lottery-style product rather than a guaranteed-return investment, meaning outcomes will still vary widely between individual savers regardless of the improved overall odds.
