Premium Bonds offered by the government-backed National Savings & Investments (NS&I) are the UK’s most popular savings product. Each £1 bond is entered into a monthly draw, with two lucky bondholders bagging £1m each.

However, there are a host of other prizes too, ranging in size from £25 to £100,000. In total for the September draw, more than 3.1 million prizes will be paid out, worth more than £89m. See YourMoney’s Premium Bonds guide for more information.

Alun Williams, assistant director at NS&I, said: “ERNIE, responsible for drawing the numbers that make up the three million plus prizes that are paid out every month, has made a Premium Bonds millionaire in every county now, but some have been touched by Premium Bonds joy more than others.

“This month sees just the second Northamptonshire Premium Bonds millionaire after nearly ten years, while Agent Million is getting used to the trips to Essex, with the third visit to the county since October 2017 and the second already this year.”

Unclaimed Premium Bond prizes

There are over 1.5 million unclaimed Premium Bond prizes, worth nearly £60m. In Essex, there are 40,500 unclaimed prizes dating back to February 1964 and totalling nearly £1.6m. The highest unclaimed prize is £25,000, won in May 2014. This person has £2,325 invested and the winning Bond number is 135MM985708.

In Northamptonshire, unclaimed prizes date back to October 1965. There are currently 11,000 outstanding, worth more than £400,000. The highest unclaimed prize is £5,000, waiting to be claimed by a Premium Bond holder with just £5 invested. The draw was in November 2014 and the winning Bond number is 6EL220580.

Premium Bonds prizes may go unclaimed as holders may not keep NS&I up-to-date on changes to contact details or if Premium Bonds were bought for the customer as a child and they have lost track of them.

You can check the Premium Bonds prize checker on the NS&I site or you can write to NS&I, quoting your name and address, any former names and addresses, date of birth and your Premium Bonds holder’s number (if known) and it will search to see if you’re a lucky recipient.

To keep track, you can opt to have prizes paid directly to your bank account, or to have the prizes auto-reinvested to be eligible for the next Premium Bonds draw, as long as the total is below the maximum threshold of £50,000.
