Premium Bonds: NS&I announces August 2025 winners

Customers are given the opportunity to win up to £1million through the prize draw with other cash prizes of up to £100,000, £50,000 and £25,000 also up for grabs.

Smaller cash prizes are also available through the NS&I product, however Premium Bonds has become well known for the jackpot prize worth £1million.

Who won August’s £1million prize?

Two Premium Bonds holders have become millionaires in the latest prize draw for August, each taking home £1 million tax-free.

The first winner is from Central Bedfordshire and held £7,000 in Premium Bonds. Their winning number, 148YD123622, was purchased in December 2008.

The second winner, based overseas, had £50,000 invested. Their winning bond, 205XQ030808, was bought in May 2013.

Both prizes are entirely tax-free and were awarded through NS&I’s monthly draw.

The jackpot winners were picked by ERNIE, the Government’s Electronic Random Number Indicator Equipment, which selects prize winners each month from over 24 million Premium Bond holders.

Premium Bonds savers will see fewer high-value prizes this month as the prize fund rate has been reduced.

From the August draw, the fund rate has dropped to 3.60 per cent, down from 3.80 per cent.

While the odds of winning remain the same at 22,000 to one, the number of bigger prizes is falling. There are expected to be 75 prizes of £100,000 in August, down from 79 in June. But even as fewer large prizes are being handed out, many people could be missing out on money they’ve already won.

LATEST DEVELOPMENTS:

NS&I has confirmed the Premium Bonds winners for AUGUST 2025

Thousands of savers have recently received surprise windfalls after being reunited with forgotten Premium Bonds and old savings, according to new figures from NS&I.

However, many more could still be sitting on unclaimed cash without knowing it.

As of June 2025, over 2.5 million Premium Bond prizes remain unclaimed, worth more than £103 million.

That includes 11 prizes of £100,000, 19 worth £50,000, 38 at £25,000, and 75 prizes of £10,000, prizes that could still legally be claimed.

Some of the prizes date back decades

Some of the prizes date back decades, with many savers having moved home or changed contact details without updating NS&I.

In the 2024–25 financial year alone, more than £166 million was returned to savers who had lost touch with their accounts. NS&I said it successfully traced 52,693 accounts using its dedicated tracing service and the My Lost Account tool.
