National Savings & Investments (NS&I) currently holds approximately 119.9 million pounds in unclaimed Premium Bonds prize money. This sum is distributed across approximately 2.78 million individual unclaimed prizes, according to May 2026 disclosures compiled by MoneyWeek. Critically, these prizes do not expire under NS&I's rules; a prize won in the 1950s remains claimable today by the original bondholder or their eligible heirs.
How much unclaimed prize money is held by NS&I?
The scale of unclaimed funds is substantial. NS&I, the UK government-backed savings institution, holds approximately 119.9 million pounds in unclaimed Premium Bonds prizes. This total covers approximately 2.78 million individual prizes that have yet to be claimed by their rightful bondholders. These prizes, which range from 25 pounds to 1 million pounds, are entirely tax-free in the United Kingdom, exempt from both income tax and capital gains tax. Premium Bonds operate as a non-interest-bearing savings product, where the equivalent of interest is paid out as monthly cash prizes through random draws. For example, the May 2026 draw alone distributed approximately 5.95 million tax-free prizes with a total value of approximately 376.18 million pounds, including two 1 million pound jackpots awarded to bondholders in Suffolk (bond 567VN857011, purchased January 2024) and the Highlands and Islands (bond 643SE292364, purchased September 2025).
A key regulatory provision states that Premium Bonds prizes do not expire. A prize won decades ago remains valid for claim by the original bondholder or their eligible heirs. This contrasts with other financial products where claim periods can be limited.
Where are the largest concentrations of unclaimed Premium Bonds?
Regional data reveals where these unclaimed sums are most prevalent. London accounts for the largest concentration, with approximately 475,253 unclaimed prizes valued at approximately 20.37 million pounds. That is a lot of money potentially waiting for London households.
The South East region follows, holding approximately 416,815 unclaimed prizes, with a total value of approximately 17.76 million pounds. These figures highlight specific geographic areas where individuals are statistically more likely to find an unclaimed prize.
What causes Premium Bonds prizes to go unclaimed?
Several factors contribute to prizes remaining unclaimed. A frequent cause is bondholders moving house without updating their address with NS&I. This prevents prize notification letters from reaching them. Without a current address, NS&I cannot inform winners of their success.
Inheritance also plays a role. Heirs of a deceased Premium Bond holder may be unaware of existing bonds or prizes. NS&I provides specific guidance for these bereavement claims. older paper Premium Bond certificates, issued before NS&I's electronic record system was fully in place, can become detached from modern records. These require contacting NS&I directly with the bond serial numbers to redeem them.
How can you check for unclaimed Premium Bonds prizes?
NS&I provides clear mechanisms for bondholders to check their prize status. The primary tool is the online prize checker available at nsandi.com. Users can enter their bond numbers to instantly see if any unclaimed prizes are associated with their holdings. This direct online access simplifies the process significantly.
Alternatively, the NS&I telephone service is available on 08085 007 007. This line is free to call from UK landlines and mobiles and can be used for both prize checking and initiating claims. Having both online and telephone options ensures accessibility for all bondholders.
Can you claim Premium Bonds prizes for a deceased relative?
Yes, heirs are explicitly entitled to claim any unclaimed prizes. NS&I's rules confirm that heirs of a deceased Premium Bond holder can claim prizes accrued during the holder's lifetime. NS&I publishes specific bereavement-claim guidance to navigate this process, ensuring that inherited entitlements are paid out. The process typically involves providing documentation such as the death certificate and proof of entitlement.
What should you do next?
Given the 119.9 million pounds sitting unclaimed, it is prudent for any current or former Premium Bond holder, or heir, to check their status. Start by gathering any known Premium Bond numbers or certificates. Visit the official NS&I website at nsandi.com and use their online prize checker. If you locate old paper certificates, have the serial numbers ready when you contact NS&I. For those managing the estate of a deceased relative, consult NS&I's specific bereavement guidance to ensure all entitlements are claimed. The UK Government fully backs all NS&I holdings and prize payouts, providing security beyond typical commercial bank deposit limits.
